Preface<br />
<strong>Behavioral</strong> science is an extremely high-yield, yet often overlooked, subject on the<br />
USMLE Step 1. Understanding important behavioral science concepts and being able<br />
to apply them to test questions can significantly increase your score. Deja Review:<br />
<strong>Behavioral</strong> <strong>Science</strong>s is the perfect format to study behavioral science material; it helps<br />
you rapidly review material you know as well as fill-in gaps in your knowledge.<br />
In this second edition of Deja Review: <strong>Behavioral</strong> <strong>Science</strong>s I have highlighted high-yield<br />
concepts such as psychiatric disorders and developmental milestones while still keeping<br />
the content comprehensive enough to use during your preclinical course and clerkship.<br />
Epidemiology and biostatistics are often tested on the USMLE—this new edition has<br />
fully revised and expanded sections on these subjects that will review and teach you<br />
core concepts needed to work through epidemiology questions on the USMLE. With a<br />
little bit of work and Deja Review: <strong>Behavioral</strong> <strong>Science</strong>s, you’ll be well-prepared for the<br />
multitude of behavioral science questions on the USMLE.<br />
ORGANIZATION<br />
All concepts are presented in a question and answer “flashcard” format that covers key<br />
facts on commonly tested topics in behavioral medicine. <strong>Behavioral</strong> science is often<br />
conceptual, and questions are designed to review and teach these concepts instead of<br />
simply memorizing material.<br />
The question and answer format has several important advantages:<br />
• It provides a rapid, straightforward way for you to assess your strengths and<br />
weaknesses.<br />
• It serves as a quick, last-minute review of high-yield facts.<br />
• It allows you to efficiently review and commit to memory a large body of<br />
information.<br />
At the end of each chapter, you will find clinical vignettes that expose you to the type<br />
of questions classically tested on the USMLE Step 1. These board-style questions put<br />
the basic science into a clinical context, allowing you apply the facts you have just<br />
reviewed in a clinical scenario and make the diagnosis.<br />
HOW TO USE THIS BOOK<br />
This text was assembled with the intent to represent the core topics tested on course<br />
examinations and USMLE Step 1. Remember, this text is not intended to replace comprehensive<br />
textbooks, course packs, or lectures. However, it may serve as a supplement
xiv<br />
Preface<br />
to your studies during your coursework and Step 1 preparation. You may use the book<br />
to quiz yourself or classmates on topics covered in recent lectures and clinical case discussions.<br />
A bookmark is included so that you can easily cover up the answers as you<br />
work through each chapter. The compact, condensed design of the book is conducive<br />
to studying on the go, especially during any downtime throughout your busy day.<br />
However you choose to study, I hope you find this resource helpful throughout your<br />
preparation. Good luck and good studying!<br />

CLINICAL VIGNETTES<br />
A woman who delivered a healthy baby boy 4 days ago comes into your clinic. She<br />
states that she has been having mood swings—sometimes laughing, sometimes<br />
crying. She feels it is impacting her care of her baby.<br />
What is the most likely diagnosis?<br />
Postpartum blues<br />
What should your treatment be?<br />
You should screen her for postpartum depression and stay vigilant for this<br />
diagnosis—but reassure her that her symptoms are normal and will likely resolve<br />
within a couple of weeks. Also, recommend that she have someone help her with<br />
child care. Be sure to distinguish this from postpartum depression—a common<br />
disorder with more severe symptoms that should be treated more aggressively.<br />
A 58-year-old woman complains of less interest in sex over the last few years. She<br />
says it is a combination of less desire and pain with intercourse. What is the most<br />
likely cause of the patient’s symptoms?<br />
Postmenopausal women have a significant decrease in estrogen, leading to vaginal<br />
atrophy, dryness, and sexual dysfunction. Topical vaginal estrogen preparations<br />
may help, as can lubricants.<br />
A 32-year-old married woman develops hallucination and delusions 2 weeks after<br />

What is the difference between<br />
bereavement and major depression?<br />
How long does bereavement last?<br />
Bereavement tends to be less severe<br />
in symptoms and less pervasive<br />
(ie, centers only around the loss).<br />
It is also self-limited and has a shorter<br />
duration.<br />
However, major depressive episodes<br />
may be superimposed onto, or<br />
precipitated by a major loss with<br />
bereavement.<br />
Normal bereavement should begin to<br />
resolve within a few months, though<br />
some grief may never go away.<br />
A DSM-IV-TR diagnosis of major<br />
depression should not be made within<br />
the first 2 months after a loss.<br />

How is the expression of the id<br />

1. Topographic theory of the mind<br />
(includes three parts):<br />
a. Conscious<br />
b. Preconscious<br />
c. Unconscious<br />
2. Structural theory of the mind<br />
(also known as the tripartite<br />
theory):<br />
a. Ego<br />
b. Superego<br />
c. Id<br />
Preconscious<br />
The conscious—this part of the mind has<br />
no access to the unconscious. The<br />
unconscious includes what we are not<br />
aware of such as sexual drives,<br />
aggressive drives, impulses, or<br />
fantasies.<br />
The ego exerts the learned rules of the<br />
world over the id to control its overt<br />
expression of primitive drives, such as<br />
sexual urges and aggression. The ego<br />
manages and negotiates the drives from<br />
the id as well as moral restrictions (from<br />
the superego).<br />

The superego (our conscience)<br />
Defense mechanisms<br />
It is associated with pleasure and<br />
instincts. This process does not involve<br />
logic or time and may not be linear.<br />
The id—this is not influenced by reality<br />
and focuses on pleasure and instinct<br />
(primary processes).<br />
A treatment technique. This treatment<br />
ranges from strengthening useful ego<br />
defenses (in supportive therapy) to<br />
challenging detrimental ego defenses<br />
and uncovering unconscious conflicts<br />
(in expressive and analytic<br />
psychotherapy), improving self-esteem,<br />
and improving relationships.<br />
To improve functionality. It helps to<br />
support defenses and functioning,<br />

conflicts, improve coping skills, have<br />
healthier relationships, and enhance<br />

8 years<br />
• Psychotherapy: 1 hour,<br />
1 to 2 × per week for 2 to<br />

Level of therapist’s participation:<br />
• Psychoanalysis: The therapist mainly<br />
listens to the patient who lies on the<br />
couch and helps guide the patient,<br />
clarify, question, gently confront,<br />
encourage, interpret, analyze,<br />
and so forth.<br />
• Psychodynamic: The therapist<br />
is more interactive while both<br />
he or she and the patient sit in chairs<br />
facing each other, though the<br />
therapist still plays a guiding role.

In displacement, the object or person<br />
receiving the negative attention is<br />
“more tolerable” to the individual<br />
(kick dog instead of boss), while in<br />
sublimation, the negative attention<br />
is channeled into an activity that is<br />
socially acceptable (vigorous<br />
exercise to relieve stress caused<br />
by boss).<br />
Humor<br />
Obsessive-compulsive personality<br />

Intellectualization (focus on facts about<br />
painful things instead of the painful<br />
things—eg, learning about treatments<br />
for cancer when diagnosed rather than<br />
feeling grief over the diagnosis.)<br />
Rationalization (making excuses that<br />
seem like a reasonable explanation—eg,<br />
I failed out of medical school because<br />
I didn’t really like biology anyway.)<br />
Isolation of affect (eg, I refuse to have<br />
emotions about this topic because<br />
emotions are too difficult.)<br />
Reaction formation (eg, I can’t deal with<br />
the fact that I hate you so I’ll give you a<br />
gift instead.)<br />
Rationalization occurs when a person<br />
uses excuses to explain an uncomfortable<br />
feeling related to an event or person.<br />
Intellectualization is when a person<br />

Which defense mechanism leads a<br />
patient to deal with an uncomfortable<br />
situation by “placing it on the back<br />
burner”?<br />
How does repression differ from<br />
suppression?<br />
Which defense mechanism is associated<br />
with a person dealing with stressful<br />
situations in a childlike manner?<br />
In which personality disorder is<br />
repression, regression, and<br />
somatization used the most?<br />
Which defense mechanism allows us to<br />
place our bad feelings about ourselves<br />
onto others?<br />
How does displacement differ from<br />
projection?<br />
Which defense mechanism causes us<br />
to take on the positive and negative<br />
behaviors of others?<br />
Which personality disorders use<br />
projection and denial as their primary<br />
defense mechanisms?<br />
How does denial differ from splitting?<br />
Suppression<br />
Repression is an immature defense<br />
mechanism that occurs when the<br />
unconscious causes us to “forget”<br />
painful information while suppression<br />
is a mature defense mechanism that<br />
allows us to consciously put off painful<br />
information and “deal with it later” in<br />
order to maintain our composure.<br />
Regression<br />
Histrionic<br />
Projection<br />
Displacement allows us to place our<br />
negative emotion about someone else<br />
onto another target, while projection<br />
allows us to place our negative<br />
emotions about ourselves onto another<br />
target.<br />
Identification<br />
Paranoid personality disorder<br />
Schizotypal personality disorder<br />
Antisocial personality disorder<br />
Borderline personality disorder<br />
In denial, patients ignore all the bad<br />
aspects about something entirely (Bob’s<br />
dog died but he is still feeding him<br />
every night). This is not a conscious<br />
action. With splitting, patients cannot<br />
see the positive and the negative at the<br />
same time (their doctors are either<br />
“horrible” or “wonderful” but never<br />
“so-so”).

Transference. It occurs when patients<br />
unconsciously reexperience relationships<br />
from their past in their current<br />
relationship. This can occur in any<br />
relationship (not just with therapists or<br />
physicians). It can be a useful tool in<br />
therapy.<br />
Countertransference. It has two parts:<br />
1. Feelings the physician has toward<br />
the patient that are related to their<br />
own past (like transference).<br />
2. Feelings that a physician has toward<br />
the patient that resembles how the<br />
patient causes most people to feel<br />
(patient specific).<br />
The physician’s countertransference can<br />
influence the way the patient is treated.<br />
It is also a useful insight in psychotherapy<br />
to recognize how the patient makes<br />
others feel about them.

CHAPTER 5<br />
Learning Theory<br />
What is behaviorism?<br />
It is a learning theory based on the idea<br />
that behavior is a product of learning<br />
through association or reinforcement.<br />
ASSOCIATIVE LEARNING VS NONASSOCIATIVE LEARNING<br />
What is associative learning?<br />
What are associative learning processes?<br />
What is nonassociative learning?<br />
What are nonassociative learning<br />
processes?<br />
Learning that occurs when a connection<br />
or pairing is made between a particular<br />
stimulus and a particular response<br />
Classical conditioning<br />
Operant conditioning<br />
Nonassociative learning describes<br />
behavior change as a result of<br />
presentation of one stimulus repeatedly.<br />
It also describes learning which has no<br />
association with an end stimulus (such<br />
as a reward or punishment).<br />
Observational learning<br />
Habituation<br />
Sensitization<br />
Associative Learning<br />
Imprinting<br />
What is imprinting?<br />
Imprinting describes learning that<br />
happens at a specific (usually early)<br />
developmental stage. It is usually rapid<br />
and is unrelated to the consequences of<br />
the behavior being learned. During this<br />
time, the animal or person imitates the<br />
behavior of another stimulus.<br />
35
36 Deja Review: <strong>Behavioral</strong> <strong>Science</strong><br />
What is an example of imprinting?<br />
When birds follow the first thing they<br />
see moving after they hatch. The critical<br />
time period is the few moments after<br />
birth and the association is made so<br />
quickly that the first object that they<br />
see suitably moving is what they will<br />
follow.<br />
Classical Conditioning<br />
What is classical conditioning?<br />
Classical conditioning is a way of<br />
pairing a stimulus and response. As<br />
demonstrated by Pavlov, a novel<br />
stimulus (a ringing bell) can be paired<br />
with an unconditioned stimulus (food)<br />
to elicit an unconditioned or natural<br />
response (salivation).<br />
Thus, if a bell (novel stimulus) is<br />
rung every time food (unconditioned<br />
stimulus) is presented to the dog,<br />
it will be conditioned to associate<br />
the bell with food and will learn to<br />
salivate (natural response) at the<br />
sound of the bell. This is the<br />
conditioned response.<br />

What is the term describing a similar<br />
stimulus to the conditioned stimulus<br />
eliciting the same response?<br />
What is a medical example of classical<br />
conditioning?<br />
What is extinction?<br />
Is it possible for the conditioned<br />
response to be paired with the<br />
conditioned stimulus after extinction<br />
has taken place?<br />
What does learned helplessness mean?<br />
What mood disorder may be explained<br />
by the theory of learned helplessness?<br />
Stimulus generalization. The classic<br />
example was “Little Albert” who was<br />
conditioned to fear a white rat and was<br />
subsequently afraid of other white<br />
fuzzy things.<br />
Phobias are believed to be results of<br />
classical conditioning. For example,<br />
Mary had a frightening experience on a<br />
ship. She may generalize that fear so that<br />
even the sight of a ship causes her<br />
anxiety.<br />
It is the disappearance of the conditioned<br />
response if the conditioned and<br />
unconditioned stimuli are no longer<br />
presented together.<br />
Yes, this is called spontaneous recovery.<br />
The effect of repeatedly pairing an<br />
adverse stimulus to the inability to<br />
escape, leading to thoughts that no<br />
efforts will be successful<br />
It has been thought that this theory may<br />
explain depression in humans. In this<br />
theory, a person has tried repeatedly but<br />
unsuccessfully to control external events.<br />
The person then pairs any adverse event<br />
to the inability to do anything about<br />
them. The person then becomes hopeless,<br />
depressed, and apathetic.<br />
Operant Conditioning<br />
What is operant conditioning?<br />
What are the different consequences<br />
in operant conditioning?<br />
It is the idea that a behavior is learned<br />
because of the reward or punishment<br />
associated with it.<br />
Positive reinforcement<br />

What is shaping?<br />
When is shaping used?<br />
What is the definition of punishment?<br />
What is the definition of extinction<br />
in operant conditioning?<br />
What is an example of extinction?<br />
Any event or stimulus that increases the<br />
likelihood of the behavior occurring<br />
again<br />
Presentation of a rewarding stimulus<br />
after a certain behavior is performed.<br />
For example, parents may reward their<br />
children with ice cream (positive<br />
reinforcer) when their rooms are clean,<br />
thus increasing the likelihood that the<br />
children will clean their rooms.<br />
Removal of an aversive stimulus after a<br />
certain behavior is performed. For<br />
example, parents may exempt the<br />
children that clean their rooms from<br />
having to take out the trash, thus<br />
increasing the likelihood that the<br />
children will clean their rooms.<br />
Positive and negative reinforcement<br />
Punishment (note the contrast between<br />
negative reinforcement and punishment)<br />
Shaping is learning that occurs when a<br />
person is rewarded for a behavior<br />
which is similar to a desired behavior.<br />
Subsequently, only behavior which is<br />
more and more similar to the particular<br />
desired behavior is rewarded.<br />
It is a progressive modification of<br />
behavior which occurs by reinforcement<br />
of behavior which is close to the desired<br />
outcome.<br />
Presentation of an aversive stimulus to<br />
reduce the likelihood of an unwanted<br />
behavior occurring<br />
Extinction is the disappearance of a<br />
certain behavior when the reinforcement<br />
is no longer present.<br />
A rat that is initially trained to press a<br />
bar if rewarded with food will quickly<br />
cease to press the bar if food is no<br />
longer obtained by the behavior.
Learning Theory 39<br />
What are the different schedules of<br />
reinforcement?<br />
Which reinforcement shows the fastest<br />
extinction when reinforcement is<br />
taken away?<br />
What is variable ratio reinforcement?<br />
What is the difference between<br />
classical and operant conditioning?<br />
There are five types of reinforcement<br />
schedules:<br />
1. Continuous: every time behavior is<br />
performed<br />
2. Fixed ratio: set number of times<br />
3. Variable ratio: random number of<br />
times<br />
4. Fixed interval: set amount of time<br />
5. Variable interval: random amount of<br />
time<br />
Continuous<br />
Reinforcement is given at a variable<br />
time interval after the behavior is<br />
performed. This type of reinforcement<br />
shows the slowest extinction when the<br />
reinforcement is taken away. Slot<br />
machines are an example of variable<br />
ratio reinforcement.<br />
Classical conditioning refers to behaviors<br />
learned by association of stimuli and<br />
responses whereas operant conditioning<br />
refers to behaviors learned by the<br />
reward and reinforcement associated<br />
with them.<br />
NON-ASSOCIATIVE LEARNING<br />
What is observational learning?<br />
If a person observes others and then<br />
imitates their behavior, what is that<br />
behavior called?<br />
What four aspects are needed in order<br />
for a person to be able to model?<br />
In observational learning, the observer’s<br />
behaviors change based upon observing<br />
the model’s behaviors. The consequences<br />
of the model’s behaviors, whether they<br />
are positive or negative, have an effect<br />
on the observer’s behaviors.<br />
Modeling. Modeling is a type of<br />
observational learning. Compared to<br />
operant learning it is a more efficient<br />
and faster type of learning. Modeling is<br />
useful in acquiring new skills.<br />

2. Retention of details<br />

What is an example of flooding?<br />
How do you describe systematic<br />
desensitization?<br />
The common saying, “see one, do one,<br />
teach one,” is a description of modeling<br />
in learning how to do medical<br />
procedures.<br />
Yes. Modeling may occur when a child<br />
models the actions of a parent with a<br />
particular phobia and hence also acquires<br />
the same phobia or perpetuation of<br />
abuse by an abused person.<br />
Yes. Modeling may involve other<br />
types of learning, eg, seeing a role<br />
model/mentor’s behavior achieve<br />
a positive result would then act as<br />
a positive reinforcer (which would<br />
be an example of operant<br />
conditioning).<br />
Habituation occurs when stimulus<br />
presentation results in decreased<br />
responsiveness.<br />
You may notice the hum of the air<br />
conditioner when it first comes on,<br />
but due to habituation, your<br />
awareness of that continual hum<br />
will decrease and you can focus<br />
on your studies.<br />
Habituation is used to overcome<br />
phobias. Some of the specific techniques<br />
using habituation are flooding and<br />
systemic desensitization.<br />
It is excessive presentation of the<br />
stimulus to achieve quick habituation<br />
by preventing escape and forcing<br />
a reduction in the associated<br />
behavior.<br />
One could force an individual with<br />
an obsession about germs to touch<br />
a toilet.<br />
In systematic desensitization, the<br />
patient is gradually exposed to<br />
anxiety-producing situations while<br />
simultaneously teaching relaxation or<br />
anxiety-reducing techniques.

Beta waves. These are of highest<br />

They are found over the frontal lobes in<br />
a person who is awake with their eyes<br />
open. These are associated with a<br />
person who is alert and actively<br />
concentrating. In a person who is awake<br />
with their eyes closed, alpha waves are<br />
seen typically over the occipital and<br />
posterior parietal lobes.<br />
Stage 1 (light sleep) is associated with<br />
theta waves and Stage 2 (deeper sleep)<br />
is associated with sleep spindles and<br />
K-complexes.<br />

other physiologic changes occur in<br />
REM sleep?<br />
How is this different from the<br />
physiologic changes in NREM sleep?<br />
Which neurotransmitter usually<br />
initiates sleep?<br />
REM latency is the length of time after<br />
falling asleep before REM sleep occurs.<br />
REM latency in an adult is approximately<br />
90 minutes. The REM sleep cycle then<br />
repeats itself approximately every<br />
90 minutes thereafter.<br />
Pulse, respiration, blood pressure, and<br />
brain oxygen use increase. There is<br />
penile/clitoral erection, dreaming, and<br />
decreased skeletal muscle tone.<br />
In NREM, blood pressure, pulse, and<br />
respiration are slow. There may also be<br />
intermittent limb movements.<br />
Tip: This makes sense—if your blood<br />
pressure (BP) and pulse are up and<br />
your genitals are aroused, NREM sleep<br />
wouldn’t be very restful!<br />
Serotonin. It is released from the dorsal<br />
raphe nucleus and is a derivative of<br />
tryptophan. It increases total sleep time<br />
and slow wave activity.<br />

is why you get sleepy after a big<br />

Sleep <strong>Science</strong> and Disorders 45<br />
Which neurotransmitters are involved<br />
in REM sleep?<br />
How does REM change with age?<br />
What effect does dopamine have on the<br />
sleep cycle?<br />
Acetylcholine (ACh) from the basal<br />
forebrain and norepinephrine (NE) from<br />
the locus ceruleus. ACh increases REM<br />
sleep and NE decreases it.<br />
Time spent in REM decreases with age.<br />
Dopamine increases wakefulness. Thus,<br />
antipsychotics, which block dopamine,<br />
can result in increased sedation.<br />

dopamine, promote wakefulness.<br />

Sleep disturbances that arise from<br />
endogenous sources, not from substance<br />

psychiatric problems. Primary sleep<br />
disorders are divided into two major<br />
categories:<br />
1. Parasomnias<br />
2. Dyssomnias<br />
Dyssomnias are due to dysfunctional<br />
sleep regulation characterized by<br />
problems initiating or maintaining<br />
sleep, or excessive daytime sleepiness.<br />
Parasomnias involve abnormal behaviors<br />
or physiologic events during sleep,<br />
rather than abnormal functioning of the<br />
usual mechanisms of sleep. These include<br />
sleep terror disorder, sleepwalking<br />

to treat narcolepsy?<br />
Why are people with breathing-related<br />
sleeping disorder chronically sleepy<br />
during the day?<br />
What is the most common cause<br />

and how is it treated?<br />
In a patient with excessive fatigue,<br />
what might the patients’ bed partner<br />
tell you about their sleep that might<br />
lead you to suspect obstructive sleep<br />
apnea (OSA)?<br />
What are the complications from<br />
untreated OSA?<br />
Set a regular bedtime, abstain from<br />
caffeine and alcohol, use the bed only<br />
for sleep and sex, and avoid daytime<br />
naps and strenuous exercise or large<br />
meals just before bedtime. Collectively,<br />
this is referred to as sleep hygiene.<br />
Kleine-Levin syndrome<br />
Cataplexy: sudden loss of muscle<br />
tone associated with strong emotions<br />
Hypnagogic and hypnopompic<br />
hallucinations: REM intrusions that<br />
occur during the transition period<br />
between sleep and wakefulness<br />
(Hypnagogic symptoms occur when<br />
going to sleep and hypnopompic occur<br />
while waking up.)<br />
Sleep paralysis: inability to move just<br />
before going to sleep or awakening<br />
Stimulants, eg, Ritalin<br />
During the night they frequently stop<br />
breathing and then are awoken by<br />
hypoxia. These frequent arousals<br />
prevent the patients from getting deep,<br />
restful sleep.<br />
Obstructive sleep apnea (OSA)<br />
Treatment: continuous positive airway<br />
pressure (CPAP) and possibly removal<br />
of tonsils and adenoids (ideally weight<br />
loss would be primary intervention<br />
in the obese.)<br />
Loud snoring and periods of time<br />
where the patient appears to stop<br />
breathing<br />
Hypertension, pulmonary hypertension,<br />
and increased all-cause mortality,<br />
cardiovascular disease, and<br />
cerebrovascular disease

benzodiazepines?<br />
What are the three most common causes<br />
of a circadian rhythm sleep disorder?<br />
During which phase of sleep would<br />
you expect nightmares to occur in?<br />
What are the similarities between sleep<br />
terrors and sleepwalking?<br />
How could you clinically differentiate<br />
sleep terror from sleepwalking?<br />
What is the treatment of sleep terrors<br />
and sleepwalking?<br />
You risk further compromising the<br />
patient’s ventilation by respiratory<br />
depression.<br />
1. Delayed sleep phase—“night owls,”<br />
more common in adolescents and<br />
tends to improve with age<br />
2. Jet lag—typically resolves over<br />
several days<br />
3. Shift work—eg, working the<br />
night shift<br />
REM<br />
Both are more common in children and<br />
may involve semicomplex to complex<br />
motor behaviors. Patients tend to be<br />
amnestic for both and in adulthood they<br />
are equally prevalent in men and<br />
women (1% prevalence of sleep terrors<br />
and 2% prevalence of sleepwalking).<br />
Both occur in slow wave sleep.<br />
Sleep terror has strong component of<br />
autonomic arousal and fear, often<br />
beginning with a terrified scream, and a<br />
lesser element of semipurposeful motor<br />
behaviors. Sleepwalking has minimal<br />
autonomic arousal/fear and motor<br />
behaviors are usually more complex.<br />
Children will usually grow out of them.<br />
Benzodiazepines can be helpful for<br />
adults, as can scheduled awakenings<br />
and environmental control.<br />
OTHER SLEEP CHANGES<br />
What polysomnogram (PSG) findings<br />
are characteristic of major depression?<br />
Reduced slow wave sleep (less delta<br />
waves), frequent nighttime awakenings,<br />
increased sleep latency (time until<br />
falling asleep), short REM latency<br />
(REM cycle starts sooner than normal<br />
90 minutes onset), and early morning<br />
waking.<br />
Tip: Low serotonin is associated with<br />
depression; therefore you would expect<br />
reduced total sleep and slow wave sleep.

CLINICAL VIGNETTES<br />
A 51-year-old obese man presents to your clinic because of fatigue. He states that<br />
he is sleepy all the time and will often fall asleep at inopportune times—at<br />
meetings, during lunch, and even behind the wheel. He says that he goes to bed at<br />
10 PM and wakes up at 6 AM every morning. He denies any substance use. What<br />
should he be screened for?<br />
Sleep apnea. Obese patients are at increased risk for this and can often present as<br />
daytime sleepiness as sleep is not restorative. He should be evaluated with a sleep<br />
study. First-line treatment is CPAP.<br />
A 32-year-old woman is being evaluated because of strange “spells”. She often<br />
seems to “pass out” when she is startled or when she laughs quite hard. What<br />
sleep disorder is she most likely suffering from?<br />
Narcolepsy. The described phenomenon is cataplexy.<br />
An 83-year-old woman presents to your office because she feels as though she is<br />
spending less time getting a restful sleep at night. She has heard from her friends<br />
that there are changes in sleep that occur with aging. What stages of sleep tend to<br />
decrease with age?<br />
Both REM and later stage deep sleep (3 and 4) decrease in the elderly, as well as a<br />
decrease in overall quantity of sleep.

CLINICAL VIGNETTES<br />
A family who has newly immigrated to the United States comes to your family<br />
practice to establish care. The son in the family has been suffering from a chronic<br />
cough and the parents are worried. Upon examination you find well-demarcated,<br />
circular, purpuric lesions on his back. They don’t look accidental. What should you<br />
do?<br />
Ask the family about their cultural practices. This could represent a cultural<br />
healing technique such as “cupping” used to heal the boy’s cough. It is important<br />
to distinguish this from child abuse.<br />
A 21-year-old female college student decides to go on a date with her boyfriend of<br />
2 years. She consumes a large volume of alcohol while out. When they return to<br />
her dorm room, the boyfriend tries to coerce her into having sex with him. She<br />
passes out without agreeing. Since they’ve had had sex before, he cites their longterm<br />
relationship as proof of consent. Would this incident be considered sexual<br />
assault?<br />
Yes—a long-term relationship (or even marriage) does not substitute or replace<br />
consent. Even if the woman agreed to intercourse, an intoxicated person is unable<br />
to give consent and the act would still be considered sexual assault.

CHAPTER 9<br />
Suicide<br />
SUICIDE<br />
What is important to keep in mind<br />
when approaching the topic of suicide<br />
on the United States Medical Licensing<br />
Exam (USMLE) Step 1?<br />
Where does suicide rank as a cause of<br />
death in the United States?<br />
What are risk factors for committing<br />
suicide?<br />
Who commits suicide more frequently,<br />
men or women?<br />
There is only a limited amount of<br />
information that you will be asked<br />
regarding suicide. Always think safety<br />
first when given a question regarding a<br />
psychiatric disorder. Statistics,<br />
demographics, and risk factors, and<br />
comorbid medical disorders will<br />
probably be the focus of the exam<br />
content. Many of the questions will<br />
come in the form of a case scenario<br />
written to ascertain if you know the<br />
correlation between suicide and<br />
comorbid mental health diagnoses such<br />
as depression, bipolar disorder, and/or<br />
chemical dependence.<br />
As of 2002, suicide ranks 10th as the<br />
leading cause of death.<br />
White male, >65 years old<br />
Gun in the house or easy access to<br />
firearms<br />
Comorbid depression, substance abuse,<br />
and/or other psychiatric illness<br />
Recent loss or stressor<br />
Serious medical illness<br />
Feelings of hopelessness and<br />
impulsivity<br />
Men are four times more likely to<br />
complete suicide, though women are<br />
more likely to attempt suicide.<br />
65
66 Deja Review: <strong>Behavioral</strong> <strong>Science</strong><br />
What accounts for this difference?<br />
What age group has the highest<br />
suicide rate?<br />
Men tend to use more lethal means<br />
(firearms, hanging) and women less<br />
lethal (pill overdose).<br />
• The elderly (65 and older). Despite<br />
being only 14% of the population,<br />
they comprise about 18% to 25%<br />
of the total suicide percentage.<br />
• The elderly suicide rate is 40 per<br />
100,000 persons in comparison to the<br />
national US rate of 12 per 100,000.<br />
What has happened to the suicide rate It has risen significantly over the last<br />
in child and adolescent groups over 40 years with a mortality rate of 12%,<br />
the last 40 years? though declined since 1990.<br />
What is the most significant risk factor<br />
of suicide?<br />
What are other risk factors for suicide<br />
(in decreasing order)?<br />
How is suicide most commonly<br />
committed or attempted?<br />
Is there racial disparity among those<br />
who commit suicide?<br />
What are the most common comorbid<br />
medical disorders associated<br />
with suicide?<br />
A previous attempt.<br />
You should become extremely cautious<br />
if the attempt is recent (eg, within<br />
3 months) and if the nature of the<br />
attempt is well-thought out and<br />
deliberate.<br />
1. Persons >45 years<br />
2. Alcohol dependence<br />
3. History of violence or aggression<br />
4. Male gender<br />
Firearms are the number one method<br />
for completed suicide, regardless of<br />
gender.<br />
Other common methods include<br />
jumping, hanging, overdose,<br />
and drowning.<br />
Yes, whites commit suicide more than<br />
any other group. However, the suicide<br />
rate among young black males is slowly<br />
increasing.<br />

Suicide 67<br />
At what stage, in treated major<br />
depression, is suicide attempted?<br />
Are there special concerns about<br />
children and adolescents treated<br />
for depression?<br />
When do you assess for suicidality?<br />
What is the difference between active<br />
and passive suicidal ideation?<br />
Can suicide attempts be predicted?<br />
How can suicidal ideation be managed?<br />
What antidepressant would be the first<br />
choice in a suicidal patient?<br />
For adults, suicide is most attempted<br />
after pharmacologic treatment has<br />
begun. The patient has more energy and<br />
is better able to function but low mood<br />
and hopelessness may persist.<br />
There is FDA black box<br />
warning for all antidepressants that<br />
use in children and adults younger than<br />
25 may increase suicidal thoughts and<br />
behaviors. When starting such a<br />
medication in this population, frequent<br />
and close monitoring for suicidality is<br />
important.<br />
At every follow-up assess for:<br />
• Ideation<br />
• Plan (possibility and practicality)<br />
• Intent to carry out the plan<br />
• Access to firearms<br />
Passive: Patient would like to be dead<br />
(eg, “I wish I were dead!”)<br />
Active: Patient actually wants to harm<br />
him/herself (eg, “I am going to shoot<br />
myself with a gun.”)<br />
There is no reliable means to predict<br />
suicide attempts with a reasonable<br />
degree of specificity and sensitivity.<br />
If suicide risk is imminent, the patient<br />
must be detained and the appropriate<br />
mental health care sought.<br />
If suicide risk is not imminent,<br />
assessment and defusing risks is<br />
important (eg, removing firearms from<br />
house, involving family members<br />
if possible).<br />
Antidepressant medication should be<br />
started and the patient should be<br />
followed closely and seen frequently.<br />
Aggressive SSRI (selective serotonin<br />
reuptake inhibitor) therapy is the best<br />
choice—avoid monoamine oxidase<br />
(MAO) inhibitors and tricyclics in a<br />
patient with active suicidal ideation as<br />
they can be lethal in an overdose.
68 Deja Review: <strong>Behavioral</strong> <strong>Science</strong><br />
What are protective factors from<br />
suicide?<br />
• Marriage: Single persons that are<br />
divorced, have never married, or<br />
widowed have higher suicide rates<br />
than married persons. Living alone<br />
and limited social and family support<br />
are also risk factors.<br />
• Employment: Persons who are<br />
unemployed have higher suicide<br />
rates. However, among employed US<br />
citizens, those working in professional<br />
roles (doctors, lawyers, and in law<br />
enforcement) have higher suicide<br />
rates than nonprofessional persons.<br />
• No family history of a completed<br />
suicide or an attempted suicide is<br />
protective because once suicide<br />
occurs, it seemingly decreases the<br />
social “taboo” of suicide in the family.<br />
CLINICAL VIGNETTES<br />
A patient in your outpatient clinic presents with suicidal ideation, but no current<br />
intent to harm himself. You would like to decrease the probability of him<br />
committing suicide and so prescribe him a high-dose SSRI. Will this eliminate his<br />
suicide risk?<br />
Though aggressive treatment is indicated and untreated depression carries a high<br />
risk of suicide, treatment with SSRI alone will not necessarily eliminate risk of<br />
suicide. Screening for associated risk factors such as access to firearms and other<br />
lethal means is also indicated.

Psychotic Disorders<br />
INTRODUCTION<br />
What is the most used book of criteria<br />
for the diagnosis of psychiatric<br />
disorders?<br />
What are the five axes used in the<br />
DSM-IV-TR?<br />
What is an important criterion<br />
of most DSM-IV-TR disorders?<br />
What strategy will help when learning<br />
the different types of disorders?<br />
DSM-IV-TR<br />
1. Axis I: Major psychiatric disorder<br />
2. Axis II: Personality disorders and<br />
mental retardation<br />
3. Axis III: Medical conditions<br />
4. Axis IV: Environmental factors<br />
5. Axis V: Global assessment of<br />
functioning (0-100)<br />
The symptoms cause significant<br />
social or functional impairment.<br />
This distinguishes a disorder from<br />
a normal variant.<br />
Try to focus on differences between<br />
similar disorders—they may have to<br />
do with duration, severity, or subtle<br />
features present or absent in a disorder.<br />
DISORDERS<br />
What is psychosis?<br />
What are the clinical hallmarks<br />
of psychosis?<br />
Significant impairment in reality<br />
testing (ability to distinguish real<br />
from imaginary)<br />
Delusions: fixed false beliefs, despite<br />
evidence to the contrary<br />
Hallucinations—usually auditory<br />
Disorganized speech (thought disorder)<br />
Grossly disorganized or catatonic<br />
(stupor and bizarre posturing) behavior<br />

What is the difference between<br />
a hallucination and an illusion?<br />
Name the six major primary psychotic<br />
disorders.<br />
Other than primary psychotic disorders,<br />
what other types of psychiatric illness<br />
often manifest psychotic symptoms?<br />
An illusion is the misperception of<br />
an actual sensory stimulus (eg, seeing<br />
a pool of water on the road ahead<br />
during a hot summer day),<br />
whereas hallucinations are<br />
perceptions in the absence of<br />
an external stimulus.<br />
1. Brief psychotic disorder (6 months of<br />
symptoms)<br />
4. Schizoaffective disorder<br />
5. Delusional disorder<br />
6. Shared psychotic disorder<br />
• Mood disorders: Major depression or<br />
manic episodes may include psychotic<br />
symptoms, but only during a mood<br />
disturbance.<br />
• Substance use: Acute intoxication<br />
(especially with cocaine, lysergic acid<br />
diethylamide [LSD], phencyclidine<br />
[PCP], and amphetamines) or<br />
withdrawal (especially alcohol).<br />
Anytime a patient has tactile<br />
hallucinations, you should think<br />
about drugs.<br />
• Personality disorders: May be<br />
associated with brief (not sustained)<br />
periods of psychosis.<br />
• Cognitive disorders: Both delirium<br />
and dementia demonstrate psychosis.<br />
Often delirium will have visual<br />
hallucinations in addition to clouded<br />
sensorium.<br />
• Psychosis due to a general medical<br />
conditions such as Vitamin B 12<br />
deficiency, Multiple Sclerosis (MS),<br />
Systemic Lupus Erythematosus (SLE),<br />
uremia, etc.<br />
• Narcolepsy: May have<br />
hypnagogic and hypnopompic<br />
hallucinations.
Psychotic Disorders 87<br />
Schizophrenia<br />
Which of the primary psychotic<br />
disorders is the most common?<br />
What are the DSM-IV-TR criteria<br />
for Schizophrenia?<br />
What are negative symptoms?<br />
What are considered the positive<br />
symptoms of schizophrenia?<br />
What is a “first-rank” symptom?<br />
How does the criterion of<br />
disorganized speech, (also referred<br />
to as thought disorder) manifest<br />
in schizophrenia?<br />
Schizophrenia. The incidence<br />
in the adult population is<br />
around 1%.<br />
Two or more characteristic symptoms:<br />
• Delusions<br />
• Hallucinations<br />
• Disorganized speech<br />
• Grossly disorganized behavior<br />
• Negative symptoms<br />
And social/occupational dysfunction<br />
And disturbance lasting 6+ months<br />
(including any prodrome or<br />
residual)<br />
And not due to Schizoaffective disorder<br />
or General Medical Condition or<br />
substance use<br />
Negative symptoms (think deficits) include<br />
affective flattening, alienation (social<br />
withdrawal), alogia (poverty of<br />
speech), and avolition (lack of<br />
motivation).<br />
Usually this refers to the hallucinations,<br />
delusions, bizarre behavior, and thought<br />
disorder.<br />
A particularly bizarre delusion, or<br />
hallucinations consisting of either a<br />
voice running commentary on the<br />
patient’s activities or two voices<br />
conversing. A first-rank symptom<br />
may satisfy both symptom<br />
requirements of the DSM-IV-TR<br />
criteria above.<br />
Abnormalities in thought processes and<br />
thought formation
88 Deja Review: <strong>Behavioral</strong> <strong>Science</strong><br />
Give at least two examples of abnormal<br />
thought formation.<br />
• Word salad: Words and phrases are<br />
combined together in incoherent<br />
manner.<br />
• Neologisms: Creation of new words.<br />
• Echolalia: Repeating the same word<br />
over and over (almost like a mental<br />
stutter).<br />
• Loose associations: Illogical shifting<br />
between unrelated or obliquely<br />
related topics.<br />
• Thought blocking.<br />
• Circumstantial and tangential<br />
thought: Circumstantial thought<br />
eventually gets to the point;<br />
tangential never does.<br />

What is meant by the prodromal and<br />
residual phases of schizophrenia?<br />
How long must you have symptoms for<br />
before schizophrenia can be diagnosed?<br />
How does schizophreniform disorder<br />
differ from schizophrenia?<br />
These are periods of time before and<br />
after active psychotic periods,<br />
respectively. These periods are<br />
generally characterized by attenuated<br />
symptoms of the active phase, eg, social<br />
withdrawal, peculiar behavior, or odd<br />
affect.<br />
During these periods a person would<br />
seem strange but would not necessarily<br />
meet criteria for psychotic.<br />
At least 6 months including prodromal<br />
and residual phases, but they must have<br />
at least 1 month of active characteristic<br />
symptoms (above), as well as decline in<br />
function.<br />

Does gender affect the development<br />
of schizophrenia?<br />
What other epidemiological factors<br />
are correlated with increased risk<br />
of schizophrenia?<br />
What is downward drift?<br />
What is the dopamine hypothesis?<br />
Are there any structural brain changes<br />
associated with schizophrenia?<br />
What are the five major subtypes<br />
of schizophrenia?<br />
Which form tends to have the best<br />
social functioning?<br />
Which form is the least common?<br />
There is no difference in the prevalence<br />
of schizophrenia between men and<br />
women; however, the age of onset is<br />
affected. Men tend to develop it<br />
between 15 and 25 years of age and<br />
women between 25 and 35 years of age.<br />
Having a first degree relative with<br />
schizophrenia increases a patients’ risk<br />
of schizophrenia tenfold. Being born in<br />
the cold winter months or in an area of<br />
high population density have also been<br />
associated with increased risk (though<br />
less so).<br />
This is the tendency of schizophrenics<br />
to be of lower socioeconomic status.<br />
It is generally thought that this is due<br />
to inability to function well in society,<br />
causing a “drift” into lower<br />
socioeconomic classes.<br />
This is the classic understanding of<br />
schizophrenia, which attributes the<br />
symptoms of schizophrenia to<br />
hyperactivity of the dopaminergic<br />
system. Many other theories have<br />
been postulated, however, especially<br />
involvement of Glutamate.<br />
Increase in size in the lateral and<br />
third ventricles, generalized atrophy<br />
of the cortex, and frontal lobe<br />
abnormalities are often associated<br />
with schizophrenia.<br />
1. Paranoid<br />
2. Residual<br />
3. Catatonic<br />
4. Disorganized<br />
5. Undifferentiated<br />
Paranoid. They also tend to be slightly<br />
older at onset, and have prominent<br />
hallucinations and delusions, with a<br />
lesser component of disorganization.<br />
Catatonic. Prior to the development<br />
of antipsychotics, this form was<br />
more common.

What is catalepsy and waxy flexibility?<br />
What is the most predictive of overall<br />
prognosis in schizophrenia?<br />
Overall, schizophrenia is associated<br />
with repeated psychotic episodes, and<br />
a chronic downhill course. What<br />
features are associated with a somewhat<br />
better prognosis?<br />
Are patients with schizophrenia at risk<br />
of suicide?<br />
What is the primary treatment for<br />
schizophrenia?<br />
What is the difference between typical<br />
and atypical antipsychotics?<br />
What is EPS?<br />
How do you treat EPS?<br />
What is tardive dyskinesia?<br />
How do you treat tardive dyskinesia?<br />
Catalepsy is the ability of a catatonic<br />
patient to hold a seemingly uncomfortable<br />
position for extended periods of time.<br />
Waxy flexibility is the slight resistance<br />
given to moving the limbs, after which<br />
the patient will often hold the new<br />
position given.<br />
Level of premorbid function<br />
Abrupt onset, female gender, presence<br />
of mood symptoms, and old age at onset<br />
Yes! Over half of schizophrenics<br />
will attempt suicide at some point in<br />
their lives, and 10% will die from it.<br />
Antipsychotics.<br />
Typical antipsychotics are older and<br />
tend to work by antagonizing dopamine.<br />
Comparatively they have higher rates<br />
of extrapyramidal symptoms (EPS) and<br />
tardive dyskinesia (TD).<br />
Atypical antipsychotics are newer, have<br />
complex mechanisms, have less EPS<br />
and TD, are more expensive, and have<br />
more metabolic side effects.<br />
This includes tremor, rigidity, akathisia<br />
(inner restlessness), and acute dystonias<br />
(muscle spasm).<br />
Anticholinergics (eg, diphenhydramine<br />
and benztropine)<br />
Abnormal movements of the face,<br />
trunk, extremities, and mouth that<br />
may happen after prolonged exposure<br />
to antipsychotic medications.<br />
Early identification and removal<br />
of the offending antipsychotic drug.<br />
With early recognition, remission rates<br />
are reasonably high. Benzodiazepines<br />
can be used for mild persistent cases.
Psychotic Disorders 91<br />
What are some differences between<br />
EPS and TD to remember?<br />
What is a potentially fatal side effect<br />
of antipsychotic treatment?<br />
How does NMS present?<br />
What is the first thing you should do<br />
if a patient presents to the ER<br />
with NMS?<br />
EPS can develop quite quickly, whereas<br />
TD tends to come on after prolonged<br />
exposure to medicines—months to years.<br />
TD is not helped by anticholinergics<br />
and may become worse. TD is also<br />
more often permanent.<br />
Neuroleptic malignant syndrome<br />
(NMS). This is an idiosyncratic<br />
reaction that is more common in<br />
young men, usually after recently<br />
starting a new antipsychotic.<br />
Mortality is nearly 20%.<br />
Fever, muscle rigidity, altered mental<br />
status, and autonomic instability<br />
Stop the antipsychotic! Then care is<br />
primarily supportive.<br />
Other Psychotic Disorders<br />
What is the DSM-IV-TR criteria<br />
for Schizoaffective Disorder?<br />
What are the two types of<br />
schizoaffective disorder?<br />
How could you differentiate<br />
between a mood disorder with<br />
psychotic symptoms (eg, major<br />
depressive disorder [MDD] with<br />
psychosis or Bipolar Mania) from<br />
schizoaffective disorder?<br />
Must meet criteria for either a major<br />
depressive episode, a manic episode,<br />
or a mixed episode at the same time<br />
as meeting characteristic symptoms of<br />
schizophrenia. The schizophrenic<br />
symptoms must persist in the<br />
absence of mood symptoms.<br />
1. Bipolar<br />
2. Depressed<br />
A person that has a mood disorder with<br />
psychotic symptoms will not have<br />
psychosis without a mood disturbance.<br />
Schizoaffective patients have psychosis<br />
at some point even when they are not<br />
experiencing an affective disturbance.<br />
Tip: Look at the names! For example, in<br />
schizoaffective disorder, the emphasis is<br />
on the schizo. The primary problem is a<br />
psychotic disorder that sometimes has<br />
a mood component, whereas in MDD<br />
with psychosis, the emphasis is on<br />
MDD. The main problem is a mood<br />
disorder that when severe, may have<br />
a component of psychosis.

What is a delusional disorder?<br />
What are some types of delusions<br />
that may occur in this disorder?<br />
What is a shared psychotic disorder?<br />
Patients with delusional disorder tend<br />
to have an isolated, fixed, nonbizarre<br />
delusion (eg, the Internal Revenue<br />
Service [IRS] is after them, or their partner<br />
is cheating). Even if the delusion is<br />
unfounded, it is plausible. They are not<br />
disorganized in thoughts or affect, and<br />
patients do not meet criteria for<br />
schizophrenia.<br />
1. Erotomanic: Someone is in love with<br />
patient.<br />
2. Somatic.<br />
3. Grandiose.<br />
4. Jealous: Wife/husband is cheating.<br />
5. Persecutory: Patient is being<br />
mistreated.<br />
A rare disorder where the patient<br />
believes the delusions of another person<br />
with a primary psychotic disorder.<br />
CLINICAL VIGNETTES<br />
A 27-year-old male presents to your clinic with a 4-year history of hallucinations<br />
and delusions for which he has been intermittently managed with antipsychotics.<br />
He is currently untreated. He also complains of 4 months of depressed mood,<br />
weight loss, insomnia, fatigue, and loss of interest in activities. He denies using<br />
any illicit substances or having any other medical conditions. What is the most<br />
likely diagnosis?<br />
Schizoaffective Disorder. Note that there have been psychotic symptoms without<br />
affective symptoms present, but now also meets criteria for a depressive episode.<br />
A 76-year-old man presents with 1 year of worsening depressive symptoms. He has<br />
trouble falling asleep, feels worthless, cannot concentrate, and has thoughts of<br />
death. Over 3 years ago his wife passed away from cancer. For 6 months now he<br />
has adamantly stated that the cancer was his fault and that he was the one that<br />
killed his wife, despite all evidence to the contrary. He also often hears her voice<br />
scolding him when no one is around. What is the most likely diagnosis?<br />
Depression with Psychotic Features. Note the mood-congruent delusion in the<br />
setting of depression and psychotic symptoms that only appear during affective<br />
episode. Also remember schizophrenia rarely presents in this advanced age.

What type of psychotherapy is used<br />
to treat depression?<br />
Amitriptyline, desipramine, imipramine,<br />
and nortriptyline<br />
Yes, the monoamine oxidase inhibitors<br />
(MAOIs), considered third-line option.<br />
MAOIs are rarely used any more.<br />
The main reason for not using them<br />
is due to the drug-drug interactions<br />
and diet restrictions. If these are not<br />
strictly followed, they may cause<br />
serotonin syndrome and<br />
hypertensive crisis.<br />
A clinical entity that consists of<br />
hyperthermia, muscle rigidity, and<br />
altered mental status. This syndrome<br />
is seen when MAOIs are combined<br />
with SSRIs (mostly), Demerol,<br />
pseudoephedrine, and other<br />
medications that can increase<br />
serotonin and norepinephrine.<br />
Hypertensive crisis originates when<br />
patients who are on MAOIs ingest food<br />
rich in tyramine, like wine and cheese,<br />
or take medications such as<br />
sympathomimetics, bronchodilators,<br />
DOPA, etc.<br />

than mania.<br />
A 1-week or longer period in which<br />
criteria for both manic and major<br />

The patient has one or more manic or<br />
mixed episodes. Usually there is also a<br />
depressive episode, but this is not<br />
required for the diagnosis.

Mood Disorders 101<br />
How do you diagnose Bipolar II<br />
Disorder?<br />
Are there any drugs that induce mania?<br />
What is cyclothymic disorder?<br />
What is the prevalence of bipolar<br />
disorder?<br />
The patient has one or more major<br />
depressive episodes, plus one or more<br />
hypomanic episodes (but never any<br />
manic episodes).<br />
Yes, steroids and appetite suppressants<br />
are the main culprits. Cocaine (crack)<br />
and amphetamines may also induce it.<br />
Previously undiagnosed bipolar<br />
patients who have only been treated<br />
for a major depression may have their<br />
manic episodes precipitated by<br />
treatment with antidepressants.<br />
Cyclothymic patients meet criteria for<br />
dysthymic disorder and experience<br />
hypomanic episodes.<br />
Bipolar I has a lifetime prevalence of<br />
0.5% to 1% and a male to female ratio<br />
of 1:1. While, bipolar II has a lifetime<br />
prevalence of 0.5% and is more common<br />
in women than in men.<br />
CLINICAL VIGNETTES<br />
You are the third-year medical student on the psychiatry consult service. You and<br />
your resident are called to the ER for a patient who was recently admitted to the<br />
inpatient psychiatry service for depression and suicidal ideation. While in the<br />
hospital, he complained of having trouble sleeping and was given a medication to<br />
help both his depression and sleep problems. The patient also received a<br />
prescription for this medication when he was discharged. He now presents to the<br />
ER with a 3-hour history of a painful erection. What drug was the patient most<br />
likely given?<br />
Trazodone<br />
A patient you have been treating for depression with SSRIs comes to you for a<br />
checkup. When you ask how he is he says “The last 3 days have been fantastic!”<br />
and launches into a very long and tangential story about what he has been doing.<br />
The patient has been very productive at work, though that might have to do more<br />
with the small amount of sleep that he has been getting, but he claims that he is<br />
far too strong to need sleep. What is your new diagnosis?<br />
Bipolar, type II. This meets criteria for a hypomanic episode, but because of the<br />
lack of psychosis or need for hospitalization it is not yet mania. He is also very<br />
functional during this time.
102 Deja Review: <strong>Behavioral</strong> <strong>Science</strong><br />
A 29-year-old woman comes to the ER worried about a new rash. She has never<br />
had a rash like this before. She has no risk factors that you can identify and hasn’t<br />
been hiking in any areas with poison oak. She says she has just started therapy<br />
with an anticonvulsant drug to treat her bipolar disorder. She has no allergies that<br />
she knows of.<br />
What drug is she likely taking?<br />
Lamotrigine, a maintenance therapy for bipolar disorder. She is experiencing a<br />
drug rash, which is common with this drug.<br />
What should you do at this point?<br />
Stop the medication<br />
What is the serious complication you would like to avoid?<br />
Stevens-Johnson Syndrome. Though rash is common, rarely some patients will<br />
progress to Stevens-Johnson Syndrome.

course, it doesn’t help that she can’t concentrate anyway. What is the most likely<br />
diagnosis?<br />
Generalized Anxiety Disorder<br />
A 32-year-old man was involved in an industrial accident that killed his best<br />
friend. He was right next to him when it happened, and he remembers every bit of<br />
it. In fact, sometimes he feels like he relives it. He has recurrent nightmares about<br />
the event, can’t seem to get to sleep, and can’t face going back to work.<br />

CHAPTER 15<br />
Cognitive Disorders<br />
Name the three major categories<br />
of cognitive disorders.<br />
1. Delirium<br />
2. Dementia<br />
3. Amnestic disorders<br />
DELIRIUM<br />
What is delirium?<br />
What causes delirium?<br />
While most substances of abuse can<br />
cause delirium with acute intoxication,<br />
which three are most likely to cause<br />
delirium related to withdrawal?<br />
What factors predispose to delirium?<br />
Delirium is a disturbance of consciousness<br />
and attention that usually develops over<br />
a short period of time. The confusion<br />
and memory impairment is not better<br />
accounted for by a preexisting dementia.<br />
Any disorder that causes a disruption<br />
of brain physiology, most commonly a<br />
medical or surgical condition, medication.<br />
The cause is often multifactorial. Elderly<br />
patients and those with underlying<br />
dementia are at higher risk.<br />
Alcohol (delirium tremens),<br />
benzodiazepines, and barbiturates<br />
Acute medical illness<br />
Age: elderly and young children<br />
Preexisting brain damage: dementia,<br />
cerebrovascular disease, tumor<br />
A history of delirium<br />
Advanced Cancer<br />
What are some medications physicians<br />
give patients that contribute<br />
to delirium?<br />

A long list, including:<br />
Anticholinergics (including Benadryl)<br />
Benzodiazepines<br />
Levodopa and other dopaminergics<br />
Opioids<br />
Cardiac medications, eg, Beta-Blockers<br />
Many antibiotics

How common is delirium?<br />
Clinically, what is the hallmark<br />
of delirium?<br />
In addition to alterations in<br />
consciousness, what other features<br />
are often found in a patient<br />
with delirium?<br />
How do you test for delirium?<br />
How do you treat delirium?<br />
While treating the cause of a delirium,<br />
how do you manage a delirious<br />
patient?<br />
Very common. Roughly 15% to 20% of<br />
general hospital patients will have an<br />
episode of delirium. In patients over the<br />
age of 65, the prevalence can be as high<br />
as 30%!<br />
Altered level of consciousness<br />
(especially attention and level of<br />
arousal). It typically develops over a<br />
period of hours to days and mental<br />
status alterations wax and wane during<br />
the day, with periods of lucidity.<br />
Altered sleep-wake cycle<br />
Perceptual disturbance<br />
Impaired memory and orientation<br />
Nocturnal worsening of symptoms<br />
Psychomotor agitation<br />
Though there is no lab test for delirium,<br />
a good cognitive tool like the minimental<br />
status examination can help<br />
identify delirium. Cognitive disturbance<br />
from delirium tends to fluctuate.<br />
Treat any medical cause, stop medications<br />
that may be contributing (if possible),<br />
orient the patient frequently, and place<br />
in a well-lit room during the day.<br />
Low doses of antipsychotics, like<br />
haloperidol or an atypical antipsychotic<br />
can be helpful for agitation and<br />
hallucinations.<br />
DEMENTIA<br />
What is the core symptom of dementia?<br />
In order to diagnose dementia, what<br />
must be present in addition to memory<br />
impairment?<br />
Memory impairment<br />
At least one of the following:<br />
Aphasia (language and naming problems)<br />
Apraxia (impaired ability to do learned<br />
motor tasks, like using objects)<br />
Agnosia (difficulty recognizing or<br />
identifying objects)<br />
Disturbance of executive function (the<br />
ability to plan, organize, and carry out<br />
tasks, judgment)
Cognitive Disorders 113<br />
How does dementia differ from the<br />
normal memory changes of aging?<br />
When diagnosing dementia, what other<br />
disorders in your differential are key<br />
to rule out?<br />
What is the prevalence of dementia?<br />
What is the most common type<br />
of dementia?<br />
What is the classical clinical course<br />
for Alzheimer disease?<br />
How does this differ from the course<br />
of vascular dementia?<br />
As we age, we are less able to learn new<br />
information, and we process information<br />
at a slower speed.<br />
However, these changes do not normally<br />
interfere with the basic functioning.<br />
It is crucial that you do not miss a<br />
delirium or a depression. In the elderly,<br />
it is not uncommon for them to report<br />
multiple memory complaints. If you<br />
misdiagnose this as dementia, you will<br />
miss a potentially reversible cause of<br />
memory impairment. Likewise, if you<br />
miss a delirium, you may miss a<br />
potentially serious medical problem.<br />
Additionally, there are several potentially<br />
reversible causes of dementia that you<br />
should look for, including: neurosyphilis,<br />
vitamin B 12 , thiamine, and folate<br />
deficiencies, and normal pressure<br />
hydrocephalus.<br />
Incidence/prevalence increases with<br />
age. The prevalence is approximately<br />
1.5 % in those over 65 years of age. The<br />
prevalence increases to 20% after age 85.<br />
Alzheimer Disease (AD) represents<br />
about 50% to 60% of dementias. The<br />
second most common form is vascular<br />
dementia (formerly multi-infarct<br />
dementia)<br />
Others include front temporal (Pick<br />
and Creutzfeldt-Jakob), Parkinson,<br />
Huntington, and human<br />
immunodeficiency virus (HIV)<br />
dementias.<br />
Slow, gradual onset of memory loss<br />
and cognitive impairment (often there<br />
are problems with judgment, mood<br />
symptoms, and behavioral disturbances<br />
as well). The disease is progressive and<br />
death usually occurs within 3 years<br />
after diagnosis.<br />
Vascular dementia classically has a<br />
stepwise decline, as opposed to the slow<br />
and steady decline in Alzheimer. Onset<br />
of deficits may be abrupt, and with good<br />
control of cardiovascular risk factors the<br />
course may remain relatively stable.

of the nucleus basalis of Meynert.<br />
Cholinesterase inhibitors such as<br />
donepezil, rivastigmine, and<br />

CLINICAL VIGNETTES<br />
A 79-year-old African American woman has dementia. Her son has heard about the<br />
genetic basis for Alzheimer disease and is worried about his risk of developing the<br />
disease. Looking over her chart you see that she was high functioning 10 years prior<br />
and then first suddenly became rather mildly cognitively impaired about 7 years<br />
ago. She continued at that level until 5 years ago when she developed significant<br />
memory problems and needed some part-time help at home. Two years ago she<br />
again got worse and required assisted living. What do you tell her son about his<br />
risks of Alzheimer disease?<br />
His risk is the same as the normal population. The patient’s history with a<br />
“stepwise decline” is suggestive of vascular dementia, not AD.<br />
You are on the psychiatric consult service and called to see a psychotic patient in<br />
the ICU. The resident there tells you that the patient—a 57-year-old woman with<br />
no prior psychiatric history—is having new-onset schizophrenia. She seemed fine<br />
this morning, but this evening she has hallucinations and is yelling at the nursing<br />
staff. What is the likely diagnosis in this patient? What can be done to help, aside<br />
from medications?<br />
This patient most likely has delirium and almost absolutely does not have<br />
schizophrenia. You should be wary of diagnosing an older individual with a newonset<br />
psychotic disorder, especially when underlying medical illness is actively<br />
involved. Delirium is so common in acutely sick patients that it is called “ICU<br />
psychosis.” First and foremost, trying to alleviate the medical condition (or stopping<br />
the offending medication) which has precipitated the delirium is the first course<br />
of action. Environmental factors may help, such as cues to help orient patients to<br />
time, date, and place.

A 57-year-old man with a history of end-stage liver disease and peptic ulcers<br />
underwent surgery to repair a perforated ulcer 2 days ago. He is agitated, confused,<br />
and he believes bugs are crawling on him. He appears floridly delirious and you<br />
begin his workup. His blood work reveals no evidence of infection, his blood<br />
pressure is becoming more labile, and heart rate is increasing. Your attending<br />
physician shows up and is very concerned that he may seize. What is the most<br />

Somatoform Disorders<br />
What are the primary types<br />
of somatoform disorders?<br />
What is factitious disorder?<br />
What is malingering?<br />
What is the primary difference between<br />
somatoform disorders and factitious<br />
disorder or malingering?<br />
Somatization disorder<br />
Conversion disorder<br />
Hypochondriasis<br />
Body dysmorphic disorder<br />
Pain disorder<br />
A disease in which the patient<br />
intentionally feigns illness to assume<br />
the sick role, but with no other obvious<br />
motivation (aka Munchausen<br />
syndrome)<br />
Intentional feigning of illness for the<br />
purpose of gaining a conscious reward<br />
Somatoform disorders are unconscious<br />
behaviors, whereas behaviors in<br />
factitious disorders and malingering<br />
are consciously derived by the patient.<br />
Table 16.1<br />
Conscious Behavior?<br />
Motivation Apparent?<br />
Somatoform No No<br />
Conversion No Yes<br />
Factitious Yes No<br />
Malingering Yes Yes<br />
Are there any physical examination<br />
findings which are common<br />
in somatoform disorders?<br />
No. Disease etiology must be ruled out<br />
in these patients; however, there is no<br />
medical condition that can account for<br />
their symptoms.<br />

What is a good way to frame<br />
the possibility of a lack of general<br />
medical problem?<br />
What is a good statement to make<br />
when discussing the possibility<br />
of psychiatric treatment with a patient?<br />
SLE, Multiple Sclerosis, Myasthenia<br />
gravis, Hyperparathyroidism, Thyroid<br />
disturbance, Porphyria, Malignancy<br />
No. Supportive treatment with<br />
suggestions that psychotherapy may<br />
alleviate their distress is associated with<br />
a better prognosis. Remember that pain<br />
is a subjective experience.<br />
Reassurance that there is no serious<br />
underlying medical cause, but without<br />
dismissing their symptoms—this may<br />
alleviate some anxiety.<br />

SOMATIZATION DISORDER<br />
What are the diagnostic criteria<br />
of complaints seen in somatization<br />
disorder?<br />
Patients must manifest four pain,<br />
two gastrointestinal, one sexual, and<br />
one neurologic symptoms, all of which<br />
cannot be fully explained by medical<br />
etiology.<br />

0.2% to 2% in women and
Somatoform Disorders 119<br />
What is the treatment for somatization<br />
disorders?<br />
Regular brief appointments with the<br />
primary care provider are often useful<br />
in reassuring these patients. Unnecessary<br />
laboratory tests or procedures should not<br />
be performed. In addition, psychotherapy<br />
may be used.<br />
CONVERSION DISORDER<br />

examination of these patients?<br />
What is a common association<br />
with the onset or exacerbation<br />
of symptoms?<br />
What medical disorder can present<br />
similarly to a conversion disorder?<br />
Neurologic (motor and/or sensory)<br />
Sudden onset of blindness<br />
Paralysis<br />
Paresthesias<br />
Seizures<br />
Dramatic onset of symptoms that are<br />
often physiologically impossible<br />
Abnormalities do not have anatomical<br />
distribution and neurologic examination<br />
is normal.<br />
Often stressful life events precede the<br />
development of symptoms.<br />
Multiple sclerosis<br />
What percentage of individuals Very few—approximately 4%<br />
diagnosed with a conversion disorder<br />
in fact have a true neurological<br />
condition?<br />
Do patients with true conversion<br />
disorders sustain injury as a result<br />
of their condition?<br />
Are patients with conversion disorder<br />
distressed over their condition?<br />
No. Patients with sudden onset of<br />
blindness do not run into objects,<br />
and those with paralysis may still<br />
inadvertently move when distracted.<br />
No. These patients are often calm<br />
regarding their pseudoneurologic<br />
deficits, termed la belle indifference.<br />
Note: This is not diagnostic of conversion<br />
disorder.

intentionally derive any gain from<br />
their symptoms?<br />
What is the prognosis and duration<br />
of symptoms seen in conversion<br />
disorders?<br />
What is the treatment for conversion<br />
disorders?<br />
No<br />
Symptoms typically remit within 2 weeks,<br />
with favorable prognosis seen in paralysis<br />
and blindness, and a poor prognosis<br />
associated with seizures.<br />
Reassurance that the symptoms will<br />
improve usually results in resolution of<br />

Yes, however, the symptoms are<br />
misinterpreted by the patient as being<br />
of a greater significance.<br />
Nausea<br />
Abdominal pain<br />
Chest pain<br />
Palpitations<br />
No, men and women are equally<br />
affected.<br />
Often the person has experienced<br />
serious illness in childhood or knows<br />
someone who has died or suffered<br />
through a serious medical condition.<br />
Doctor shopping is common, as these<br />
patients are resistant to suggestions that<br />
there is no significant medical etiology<br />

Personality disorders occur when<br />
a particular feature or trait of an<br />
individual’s personality becomes<br />
inflexible or maladaptive and impairs<br />
social, occupational, or personal<br />
functioning.<br />
The patterns are pervasive and<br />

What are the three important<br />
observations about withdrawal<br />
that Himmelsbach made?<br />
What are the four central tenets<br />
that must be addressed in order<br />
to successfully treat drug dependence?<br />
How should withdrawal symptoms<br />
be prevented/treated during<br />
detoxification?<br />
1. There is a common association<br />
between tolerance and a specific<br />
withdrawal syndrome.<br />
2. The nature of the withdrawal<br />
syndrome is opposite to the<br />
acute effects of the drug.<br />
3. The withdrawal syndrome is most<br />
intense when the drug leaves the<br />
brain rapidly.<br />
1. The positive reinforcements/reward<br />
effects of the drug must be reduced.<br />
2. The negative reinforcements<br />
(withdrawal symptoms) must be<br />
treated, either by giving a substitute<br />
drug or by symptomatically treating<br />
the effects of drug removal.<br />
3. Detoxification—complete removal<br />
of the drug of dependence from the<br />
patient’s system.<br />
4. Relapse prevention by reducing the<br />
desire for the drug or by reducing<br />
cravings for the drug.<br />
Withdrawal symptoms may be<br />
prevented/treated by administering<br />
a substitute drug with a similar effect<br />
(eg, methadone for heroin,<br />
benzodiazepines for EtOH), or treating<br />
the withdrawal symptomatically<br />
(eg, treating diarrhea and<br />
GI symptoms).

How can the positive reinforcement<br />
effects of drugs be reduced?<br />
How does disulfiram work?<br />
What side effect of opiate antagonists<br />
may result in compliance problems?<br />
What are the three major ways<br />
of reducing withdrawal?<br />
What criteria should be used when<br />
selecting a substitute drug for treating<br />
withdrawal?<br />
Giving specific receptor antagonists<br />
to prevent the binding of receptors<br />
by the drug of dependence; therefore,<br />
precipitating withdrawal and preventing<br />
the effects of the drug (eg, naloxone or<br />
naltrexone treatment for opiates)<br />
Converting reward to punishment (eg,<br />
the use of disulfiram [Antabuse] for<br />
alcohol dependence)<br />
Giving dopamine or opiate antagonists<br />
to cause general inhibition of the<br />
reward pathways<br />
Negative discriminative stimuli (eg, telling<br />
the patients that their drug of choice<br />
will be ineffective; therefore, they avoid it)<br />
Disulfiram inhibits aldehyde<br />
dehydrogenase in the liver. Alcohol is<br />
then unable to be fully metabolized,<br />
leading to flushing, headache, and<br />
nausea from accumulation of the<br />
aldehyde intermediate.<br />
Anhedonia<br />
1. Substitute drugs that act as agonists<br />
for the same receptor, and therefore,<br />
prevent severe withdrawal (ie, using<br />
methadone to treat heroin or opiate<br />
dependence)<br />
2. Substitution by partial agonist for the<br />
same receptor, thereby, preventing<br />
severe withdrawal and counteracting<br />
the effects of the drug if it is taken<br />
3. Substitution of a different route of<br />
administration to prevent some of<br />
the adverse effects of the drug itself<br />
while still preventing withdrawal (ie,<br />
using the nicotine patch for smoking<br />
cessation)<br />
Substitute drugs should be:<br />
Less rewarding<br />
Less damaging<br />
More manageable<br />
Able to allow the patient to be more<br />
functional (eg, methadone)

What are some of the medical effects<br />

To use positive reinforcement<br />
treatments, the patient must undergo<br />
detoxification first.<br />
Negative reinforcement treatments<br />
may lead to polydrug abuse,<br />
especially if substitution methods<br />
are used.<br />
Detoxification uses the principle of<br />
substitution with a drug of crossdependence<br />
or different route of<br />
administration to allow for safer,<br />
slower withdrawal from the drug<br />
of dependence. It should not be<br />
used to precipitate withdrawal.<br />
75%—most within the first year<br />
Joining self-help groups → providing<br />
a different type of peer pressure and<br />
reinforcement<br />
Cognitive therapy → helps develop<br />
new and different coping skills<br />
Cravings is the most common reason<br />
for relapse. Cravings are caused by<br />
memories of the positive rewards of<br />
drug use or by conditioning cues that<br />
are endogenous or exogenous.<br />
Cravings may be treated by reducing<br />
the desire for the drug, providing a<br />
substitute for the drug reward, reducing<br />
endogenous cues for cravings (ie, by<br />
using anxiolytics or antidepressants),<br />
reducing the conditional anticipation<br />
of the reward (ie, giving naltrexone<br />
to an alcoholic), or by reducing<br />
pseudowithdrawal symptoms.<br />

1. Mu<br />
2. Kappa<br />

Mu<br />
Enkephalins act on mu and delta<br />
receptors, main actions are at delta<br />
receptors.<br />
Beta-endorphins act on mu and delta<br />
receptors equally.<br />
Dynorphins act on kappa receptors.<br />
Opioid receptors are G protein–coupled<br />
receptors with seven membranespanning<br />
segments. Activation of the<br />
receptors causes changes in cyclic<br />
adenosine monophosphate (cAMP),<br />
Ca 2+ , etc, leading to inhibition of<br />
neuronal excitation.<br />
Strong agonists have high affinity<br />
for the receptor and produce a<br />
conformational change that activates<br />
the receptor.<br />
Antagonists have high affinity for the<br />
receptor and do not activate the receptor.

What drug can be used as a narcotic<br />

Which opioids/opiates are metabolized<br />
by CYP2D6?<br />
Both strong and partial agonists have<br />
high affinity for the receptor; but unlike<br />
strong agonists, partial agonists have<br />
low efficacy to activate the receptor<br />
resulting in a weak effect. Because of<br />
this high affinity/low efficacy, they can<br />
antagonize/block the effects of a<br />
stronger agonist.<br />
Opiates are derived from the<br />
opium poppy, while opioids<br />
are synthetic or semisynthetic<br />
derivatives of opiates.<br />
The difference between kappa receptors<br />
and mu receptors is that activation of<br />
kappa receptors produces less analgesia,<br />
less respiratory depression/asphyxia<br />
(floor effect), and produce dysphoria<br />

What is the physiologic effect of<br />
ethanol’s action on glutamate receptors?<br />
In drugs that are metabolized by<br />
CYP2D6, the active metabolite is<br />
morphine.<br />
Loperamide, which works by reducing<br />
GI tract motility<br />
Methadone is used to treat withdrawal<br />
from heroin while acting to decrease<br />
cravings and risk from associated<br />
lifestyle (legal, HIV, hepatitis, etc).<br />
In narcotic overdoses, CO 2 drive is<br />
reduced resulting in respiratory<br />
depression and cyanosis and<br />
diminished mental status/coma.<br />
The very low molecular weight as<br />
well as its water and lipid solubility<br />
allow for rapid absorption of ethanol<br />
from the GI tract and entry into the<br />
brain.<br />
Absorption of ethanol is limited only<br />
by the surface area of the stomach.<br />
Its water solubility allows absorbed<br />
ethanol to be distributed throughout<br />
the body water.<br />
Ethanol’s mechanism is not completely<br />
known, but likely has to do with<br />
alteration of membrane fluidity as<br />
well as actions on GABA receptors,<br />
glutamate NMDA receptors, and<br />
the serotonin system.<br />
GABA is the major inhibitory<br />
transmitter in the brain, and ethanol<br />
potentiation of GABA causes anxiolysis<br />
and possibly the reward effects by<br />
increasing dopamine release from<br />
the nucleus accumbens.<br />
Glutamate is a major excitatory<br />
transmitter in the brain, and ethanol<br />
inhibits glutamate causing amnesia and<br />
anesthetic effects and possibly reward<br />
effects.

How is ethanol metabolized in<br />
the liver?<br />
What is zero-order elimination<br />
of a drug?<br />
Ninety-five percent of the ethanol<br />
ingested is metabolized in the liver.<br />
Alcohol metabolism is a zero-order<br />
process in which alcohol is converted<br />
by alcohol dehydrogenase to aldehydes,<br />
and then the aldehydes are converted<br />
by aldehyde dehydrogenase<br />
to acetate.<br />
Zero-order elimination occurs when a<br />
constant amount of drug is eliminated<br />
from the body per unit of time,<br />
regardless of the drug dose or<br />
serum concentration.<br />

What is the limiting factor in ethanol<br />
metabolism by the liver?<br />
Which metabolic process is responsible<br />
for the toxic effects of alcohol?<br />
What are the chronic effects<br />
of alcohol ingestion?<br />
What are the three types of tolerance?<br />
The limiting factor in alcohol<br />
metabolism is the availability of<br />
nicotinamide adenine dinucleotide<br />
(NAD) and nicotinamide adenine<br />
dinucleotide plus hydrogen (NADH),<br />
which is used by aldehyde<br />
dehydrogenase.<br />
The toxic effects of alcohol are related to<br />
metabolism of alcohol to aldehydes, the<br />
buildup of which causes liver and tissue<br />
damage, flushing, nausea, and<br />
headache.<br />
Development of tolerance<br />
Psychological dependence<br />
Physiologic dependence (this includes<br />
tolerance and withdrawal)<br />
Huge host of medical problems,<br />
including liver disease, cancer, etc<br />
1. Metabolic tolerance: allows for<br />
more rapid metabolism and<br />
excretion<br />
2. <strong>Behavioral</strong> tolerance: involves<br />
learning to perform a task while<br />
intoxicated as if the person is not<br />
intoxicated<br />
3. Neuroadaptation: involves the<br />
evolution of alterations in the brain<br />
that help to overcome the effects of<br />
the drug

A 48-year-old man comes in for an elective surgery. His operation is a great success<br />
and there are no major complications. Three days after his surgery he becomes<br />
very disoriented, and yells nonsense at the nurses. His HR is 110, his BP is 154/92,<br />
and he is febrile. His family asks you if there is anything they can do. What is a<br />
key piece of history you could ask the family about?<br />
Ask about his drinking habits. He may be in alcohol withdrawal since he has<br />
likely not had a drink since surgery.<br />
A 26-year-old woman just had her third DUI arrest. She gets drunk every night<br />
with her friends and has never had any regrets about doing it. She has lost four<br />
jobs because she is unable to show up on time in the morning. She claims she<br />
doesn’t have a problem because it only takes her 5 beers to get drunk—the same<br />
amount as when she started drinking 5 years ago. She now spends most of her day<br />
doing odd jobs so that she can afford to go out drinking. Her doctor told her that<br />
her liver is suffering, but she continues to drink. What is her likely diagnosis?<br />
She meets criteria for substance dependence, despite her lack of tolerance. She spends<br />
most of her time involved in substance-seeking behavior, has had occupational<br />
impairment, and has had a physical impact from use as well. She cannot be<br />
diagnosed with substance abuse as dependence takes precedence.<br />

friends say there has been a lot of drinking at the party as well as some pills.<br />
What drugs has the patient most likely ingested?<br />
Alcohol and opiates (note pinpoint pupils)<br />
What drug should be administered immediately after this patient arrives in the ER?<br />

What is Eating Disorder Not Otherwise<br />
Specified (NOS)?<br />
A grab-bag of disordered eating that<br />
does not meet criteria for Anorexia or<br />
Bulimia. This includes:<br />
• Purging behavior without true binge<br />
eating<br />
• Anorexia criteria without amenorrhea<br />
• Restricting type anorexia without<br />
significant weight loss (ie, no binge<br />
eating/purging to meet bulimia<br />
criteria)<br />
• Bulimia criteria except at a lower<br />
frequency than required for<br />
diagnosis<br />
• Chewing and spitting out large<br />
amounts of food<br />
• Binge eating without purging<br />
behavior<br />

A 17-year-old woman comes to your office complaining of fatigue. Upon careful<br />
examination you see erosion of the enamel on her molars. You check an electrolyte<br />
panel and find her to be hypokalemic.<br />
What are the possible psychiatric disorders that may be present?<br />
This patient may have anorexia nervosa, bulimia nervosa, or eating disorder NOS.<br />
How do you distinguish anorexia nervosa and bulimia nervosa?<br />
To distinguish these disorders you would need to know her body weight vs her<br />
ideal body weight.<br />
What is the likely cause of her hypokalemia? If you took an arterial blood gas,<br />
what would you expect the pH to be?<br />
Her hypokalemia is likely due to recurrent vomiting—this will also cause a<br />
metabolic alkalosis (think loss of stomach H + ), so you would expect her pH to be<br />
high (alkalemic).

Benzodiazepines target the GABA A<br />
(γ-aminobutyric acid A) chloride channel<br />
receptor, resulting in an increase in the<br />
receptor’s affinity for and causing the<br />
ion channels to open more frequently, thus<br />
allowing more chloride ions to pass<br />
through.<br />
Benzodiazepines can cross the placenta,<br />

CLINICAL VIGNETTES<br />
An unresponsive young woman is brought to the ER by her college roommate.<br />
Her roommate states that she had confided in her that she was being treated for<br />
depression for quite some time with little success. She found an empty pill bottle<br />
by the patient as well, but didn’t bring it in. On examination the patient has<br />
widely dilated pupils, a dry mouth, and tachycardia.<br />
What was likely in that bottle of pills taken by the patient?<br />
She likely is suffering from tricyclic antidepressant overdose. Note the anticholinergic<br />
symptoms and the limited success of treatment (perhaps necessitating a few different<br />
medication trials).<br />
What diagnostic test would you order? What result do you expect on that test?<br />
You should order an ECG, on which you would likely see a prolonged PR interval,<br />
a widened QRS, and a long QT interval.<br />
What is the appropriate management of the patient?<br />
Of course you would start with ABCs, but intravenous bicarbonate is a specific<br />
treatment for TCA overdose.<br />
A 62-year-old patient with schizophrenia comes in to inquire about new treatment<br />
options. He has been on haloperidol which has controlled his symptoms well. His<br />
past medical history includes pre-diabetes, obesity (though he’s trying to lose<br />
weight), hypertension, and a family history of coronary artery disease. He says that<br />
he has heard that some of the new atypical antipsychotics are more effective than<br />
his old agent.<br />
What should you advise him?<br />
Atypical medications are no more effective than typical agents, with the notable<br />
exception of clozapine. The main advantage of atypical agents is a more favorable<br />
side-effect profile with less EPS and tardive dyskinesia than typical agents.<br />
What side-effects might you worry about in this patient?<br />
Prominent metabolic effects and weight gain are side effects of atypical agents,<br />
which would be especially detrimental to this patient.<br />
If he was treatment resistant, would this change your thinking?<br />
Patients who have failed multiple other antipsychotic medications may benefit<br />
from clozapine—though the risk of agranulocytosis and subsequent FDAmandated<br />
laboratory monitoring limit its widespread use.

CHAPTER 23<br />
Clinical Practice and<br />
Difficult Situations<br />
The USMLE sometimes gives “quote” questions asking you to pick something to<br />
say in a provider-patient interaction. In general, it’s usually a good idea to get more<br />
information, respect the patient’s autonomy, keep information confidential, and<br />
never lie.<br />
What is the importance of rapport?<br />
What are the most important<br />
things to do if a medical error<br />
is committed?<br />
What should you do if a patient tries<br />
to give you a gift?<br />
When is it appropriate to refer a patient<br />
to another physician?<br />
What would you say to a patient with<br />
a terminal illness who wants to die?<br />
The relationship and trust built between<br />
the doctor and patient greatly enhance<br />
the effectiveness of care.<br />
Admit the mistake and apologize for it.<br />
Never try to cover up an error.<br />
You should thank the patient for their<br />
thoughtfulness, but not accept it. Gift<br />
giving may be misinterpreted as<br />
“buying better care”—equal care should<br />
be given to all.<br />
Only when the problem cannot be<br />
handled by yourself. This is rarely the<br />
answer on the USMLE—it is<br />
inappropriate to refer a patient to a<br />
psychiatrist just because they have a<br />
difficult situation to be dealt with!<br />
Get more information about why they<br />
feel this way. Commonly, they are<br />
afraid of dying in pain; they may<br />
have seen a loved one die painfully.<br />
Reassure them that you will stick with<br />
them and that their symptoms will<br />
be well controlled. Also assess for<br />
untreated depression.<br />

What if the patient starts to cry?<br />
What are the steps to giving bad news?<br />
Yes. It’s unethical to endanger patient<br />
care with a possibly impaired physician.<br />
No. You must have formal permission<br />
from the patient to share their health<br />
information with anyone other than<br />
them.<br />
No. This is a violation of the Health<br />
Insurance Portability and Accountability<br />
Act (HIPPA). You should be careful<br />
where and with whom you discuss<br />
any patient information.<br />
No. It is never ethical to have a<br />
romantic relationship with a patient,<br />
former or current.<br />
If the patient tells you they don’t want<br />
to know. It must be the patient that<br />
indicates this—not a family member.<br />
No, you do not need to do anything nor<br />
treat anyone that would compromise<br />
your beliefs. However, you should refer<br />
the patient to someone who will treat<br />
them, as well as provide support in the<br />
meantime.<br />
Label and validate their emotions, then<br />
offer support. Eg: “You sound like you<br />
are scared—I don’t blame you, it’s OK<br />
to be scared about this procedure.”<br />
Let them cry. Try to be comfortable with<br />
silence when appropriate. Offering a<br />

knows about their illness (no 2). It’s<br />
always good to get information first so<br />
you can frame the discussion.<br />
Speak to the patient, not the interpreter.<br />
Speak clearly, being sure to pause<br />
intermittently to allow the interpreter<br />
to convey information to the patient.<br />
No, not if it can be helped. Even if the<br />
family member is fluent, it is good to at<br />
least offer to get an interpreter for the<br />
patient. Family members may also have<br />
their own agenda that may unduly<br />
influence the patient.<br />

Complicated medical regimens<br />
Poor physician-patient rapport<br />
Lack of patient involvement in the<br />
treatment plan<br />
Infrequent appointments<br />
Poor support structure/inadequate help<br />

The treatment plan can be simplified by<br />
limiting:<br />
• The number of medications the<br />
patient is taking<br />
• The number of times the medications<br />
is taken per day<br />
• The number of changes made at each<br />
visit<br />
A question that is intentionally left<br />
broad, such that the patient can say<br />
what is really on their mind—“What<br />
brings you into the clinic today?” or<br />
“Tell me about your stomach pain.”<br />
A very specific question with a discrete<br />
answer. Used to get more detail—<br />
“Did you have nausea?” “How<br />
frequently do you have pain?”<br />

A 79-year-old woman came into the hospital complaining of shortness of breath.<br />
After an extensive workup, you find that she has metastatic lung cancer. Her son<br />
finds you in the hallway and states “In our culture our elders do not like to know<br />
about serious illnesses. It is my duty as a son to take care of my mother.” You are<br />
unclear about what cultural practices are appropriate to the patient. How do you<br />
approach this situation?<br />
It may very well be that there is a cultural aspect to discussions of terminal illness<br />
that is appropriate to consider in this case. If available in your institution, a “cultural<br />
consult” may be appropriate with someone more versed than you in these issues. If<br />
not, it would be inappropriate to withhold information based solely on what the son<br />
of the patient says. The best case would be to sit down with the patient and ask her<br />
about her cultural beliefs around illness—“Some members of your culture prefer<br />
not to talk about their illnesses, but instead allow their children to make medical<br />
decisions for them. How do you feel about the discussion of illness?”<br />
A patient with known sickle cell disease comes into the ER. He states he is in 10/10<br />
pain and requests 15 mg of morphine. The nurse says he is a “frequent flier” and<br />
worries that he is an addict. He doesn’t look like he’s is in any pain. What should<br />
you do?<br />
Treat his pain. With known disease it is more important that he does not suffer<br />
than to distinguish his symptoms from malingering. Remember, sickle cell crisis<br />
can be extremely painful even without outward signs of pain.<br />
You call a family meeting for a chronically ill patient whom you just found out has<br />
leukemia. Everyone is comfortably sitting in your office. What do you say next?<br />
“What do you know about your illness?” It is important to be open-ended and see<br />
what the patient’s thoughts are. Most likely he has been thinking about this much<br />
more than you and probably is very well informed; or he may have completely<br />
unrealistic views that would be good to learn about before the conversation. Probe<br />
a bit to understand this, and then to ascertain how much he wants to know before<br />
delivering the news.

What is the principle of double-effect?<br />
What is the classic example of<br />
double-effect?<br />
Is malpractice a crime?<br />
1. Patient Autonomy<br />
2. Beneficence<br />
3. Nonmaleficence<br />
4. Justice<br />
The patient has the right to make their<br />
own decisions regarding their care.<br />
The principle that physicians should be<br />
of benefit to their patients.<br />
Do no harm.<br />
The allocation of resources in a fair and<br />
just manner, including equal treatment.<br />
Patient Autonomy<br />
When an action that has a primarily<br />
good effect may also cause an<br />
unintended bad effect, but is still<br />
permissible.<br />
Giving morphine to relieve the pain of a<br />
dying patient, even if it causes respiratory<br />
depression hastening the patient’s<br />
death. As long as the primary intent<br />
of the treatment is to reduce pain and<br />
not to kill the patient, it is ethically<br />
permissible so long as there is pain<br />
to be relieved.<br />
No—malpractice is a civil court matter.<br />

The jury makes this determination based<br />
upon testimony of one or more expert<br />
witnesses who testify as to the standard<br />

Keep current with standards of care.<br />
When clinical judgment is affected by<br />

• Physical illness<br />
• Mental illness<br />
• Substance abuse<br />
No. It is the ethical duty of a physician<br />
to report an impaired health-care<br />
provider to the proper authorities.<br />
Under the American Medical Association<br />
(AMA) ethical guidelines, an HIV<br />
physician should not engage in any<br />
activity that would put a patient at risk<br />
of contracting HIV (eg, an HIV-positive<br />
surgeon may be precluded from<br />
practicing surgery. Some states require<br />
that an HIV-positive physician disclose,<br />
as part of the informed consent process,<br />
his or her HIV status before engaging in<br />
an invasive procedure that would put<br />
the patient at risk).

What happens if a patient lacks<br />
the capacity to make, understand, or<br />

decisions and has not named a healthcare<br />
agent under a durable power<br />

What is an advance directive?<br />
What is a durable power of attorney<br />
for health care?<br />
The patient only unless:<br />
• It is an emergency, delay puts the<br />
patient’s life at risk, and there is no<br />
one available to give consent on the<br />
patient’s behalf.<br />
• The patient is legally incompetent<br />
(depending upon state law, the<br />
legally appointed guardian, or the<br />
agent named in a durable power of<br />
attorney for health care gives<br />
consent).<br />
• The patient lacks the capacity to<br />
make, understand, or communicate<br />
his or her health-care decisions (a<br />
surrogate decision-maker gives<br />
consent as provided by state law,<br />
usually in the following order of<br />
priority: health-care agent, spouse, an<br />
adult child, parent, an adult sibling,<br />
or a grandparent).<br />
• The patient is a nonemancipated<br />
minor (parent or legal guardian gives<br />
consent, and in some states, someone<br />
standing in the place of a parent may<br />
also give consent).<br />
A surrogate decision-maker may give<br />
consent on the patient’s behalf and<br />
should make a good-faith effort to make<br />
decisions based upon what the patient<br />
would have chosen. State law designates<br />
a list of surrogate decision-makers,<br />
usually in the following order of priority<br />
(in the absence of a health-care agent or<br />
legal guardian): spouse, adult child,<br />
parent, adult sibling, or a grandparent.<br />
State laws may differ.<br />
A decision made by a patient about<br />
what type of medical care he or she<br />
wishes to receive in case that he or<br />
she is not able to make decisions in the<br />
future.<br />
A durable power of attorney for health<br />
care (or health-care proxy) is a legal<br />
document that allows the patient to<br />
designate a health-care agent to make<br />
health-care decisions on behalf of the<br />
patient when and if the patient is unable<br />
to do so. It is an advance directive.
Medical Ethics and Legal Issues 185<br />
What is a living will?<br />
What is a DNR (do not resuscitate) order?<br />
Do DNR orders mean no interventions<br />
are done on a patient?<br />
When does a judge consent for medical<br />
treatment of a minor?<br />
Does this apply to a fetus?<br />
Under what circumstances can a<br />
nonemancipated minor receive<br />
treatment without the consent<br />
of his or her parent or legal guardian?<br />
A living will is a legal document that<br />
allows a patient to decide, in advance,<br />
whether he or she wants to be kept<br />
alive by artificial means if two doctors<br />
diagnose that the patient is (1) terminally<br />
and incurably ill, (2) in a persistent<br />
vegetative state, or (3) in an irreversible<br />
coma. State laws may differ as to<br />
conditions under which a living will<br />
may be honored.<br />
A DNR order is an order written<br />
by a physician, after determining<br />
whether the patient is a candidate<br />
for nonresuscitation and obtaining the<br />
appropriate consent that directs medical<br />
personnel not to resuscitate a patient in<br />
the event of cardiopulmonary arrest.<br />
No. Patients may choose to still have<br />
antibiotics, fluids and nutrition, or other<br />
“non-heroic” means depending on their<br />
wishes.<br />
When a parent or legal guardian refuses<br />
to consent to medical treatment on the<br />
minor’s behalf, and the physician<br />
believes that the treatment is medically<br />
necessary and justifies court intervention.<br />
A court is more likely to intervene when<br />
the proposed treatment carries a low<br />
risk and high benefit or when the<br />
minor’s life is threatened.<br />
No. The competent pregnant mother, in<br />
most circumstances, has a right to refuse<br />
any intervention on the part of the fetus<br />
even if it compromises her own or the<br />
fetus’ life. In some states, courts have<br />
intervened on behalf of a viable fetus.<br />
Although the answer is state dependent,<br />
most states allow minors to consent for<br />
treatment involving sexually transmitted<br />
diseases (STDs), contraception and<br />
pregnancy, and alcohol or illegal<br />
substance use. Some states also allow<br />
minors to consent for an abortion.<br />
Other states allow a minor to consent<br />
to an abortion, but require parental<br />
notification or a court order waiving<br />
parental notification.

When can a patient refuse treatment<br />
even though refusal is life threatening?<br />
Does this include artificial<br />
life support?<br />
Is removing artificial life support the<br />
same as physician-assisted suicide?<br />
When can a physician decide to remove<br />
life support without the consent of the<br />
patient or patient’s decision-maker?<br />
Is palliative care of the terminal patient<br />
the same as euthanasia?<br />
What is an informed consent?<br />
Does consent have to be written?<br />
Anytime, as long as they have the<br />
capacity to refuse the treatment, and<br />
the refusal is an informed refusal.<br />
Yes<br />
No. Removing artificial life support is a<br />
decision that the competent, informed<br />
patient is allowed to make. It does not<br />
accelerate the natural course of the<br />
patient’s disease process. Physicianassisted<br />
suicide is illegal in most states<br />
because it purposely accelerates<br />
death.<br />
A physician may remove life support<br />
without consent if the patient is legally<br />
dead. The patient must be “brain dead”<br />
in order to be declared legally dead in<br />
the United States, which includes global<br />
dysfunction of the brain (coma) and<br />
absent brainstem reflexes.<br />
No. Palliative care is not done with the<br />
intention of accelerating death. It is<br />
done with the intention of making the<br />
patient comfortable through the natural<br />
end point of a terminal illness. However,<br />
palliative care may unintentionally<br />
accelerate death as a side effect.<br />
Informed consent is required if the<br />
proposed treatment or procedure<br />
involves a material risk to the patient.<br />
An informed consent includes the<br />
voluntary agreement by a patient to<br />
proceed with treatment after the<br />
physician has discussed the procedure,<br />
risks, benefits, and outcome of the<br />
procedure or treatment, alternative<br />
treatments (including no treatment),<br />
and the risk, benefits, and outcomes<br />
of those alternatives.<br />
No. Basic consent (eg, consent to<br />
touching contact during a physical<br />
examination) need not be in writing and<br />
is often implied. An informed consent<br />
should be in writing and documented<br />
in the chart.

Can a physician refuse to treat patients<br />
based on race, financial status, and<br />
presence of mental illness or<br />
HIV status?<br />
If a patient is homicidal, is a physician<br />
allowed to break patient confidentiality?<br />
In what other circumstances is a<br />
physician required to break patient<br />
confidentiality by law?<br />
Generally, a physician may refuse to<br />
treat a patient as long as the reasons for<br />
refusal are not illegal. Illegal reasons to<br />
refuse treatment include race, national<br />
origin, gender, religion, and disability<br />
(which include mental illness and<br />
HIV status). Except in emergency<br />
situations, a physician may refuse to<br />
treat a patient based upon inability<br />
to pay.<br />
Yes. In almost all states, the Tarasoff<br />
decision applies, which requires a<br />
physician to warn the person in severe<br />
danger and notify law enforcement. In<br />
states such as Georgia, Tarasoff has not<br />
been adopted. Instead, the physician<br />
has a duty to prevent harm by the<br />
patient if there is a right to control. In<br />
other words, if a physician has the<br />
legal right to initiate involuntarily<br />
commitment proceedings and fails to<br />
exercise this right, the physician may be<br />
held liable for harm done by the patient<br />
to third parties if the harm was<br />
foreseeable. Georgia has not specifically<br />
recognized a duty to warn, and<br />
thus, a physician may be breaching<br />
confidentiality in warning an<br />
intended victim.<br />

If the patient signs a written authorization,<br />

authorization. State law may also<br />
authorize a physician to share private<br />
health information with specified people<br />
who are at risk for contracting HIV from<br />
a patient. Disclosure of this information<br />
is controlled by state law, and physicians<br />
must proceed carefully because if state<br />
law does not authorize disclosing<br />
HIV/AIDS information, the physician<br />
may be guilty of violating Health<br />

crisis, then the patient needs involuntary<br />
inpatient treatment.<br />
No. Even an involuntarily committed<br />
patient has the right to refuse medical<br />
treatment.<br />
A judge can order the administration<br />
of treatment if the patient is found<br />
incompetent to refuse treatment. Also,<br />
if the patient is violent and posing an<br />
immediate, severe danger to himself or<br />
herself or others, this is considered a<br />
medical emergency and the physician<br />
may administer treatment without the<br />
patient’s consent.<br />

It may be very difficult to qualify for<br />

can also be prohibitively expensive.<br />
Insurance companies make money by<br />
having the average premium of their<br />
insured group be less than the total<br />
amount they pay out for that same<br />
group. Each person has a certain<br />
amount of “risk” for developing<br />
disease. Combining the risk to each<br />
person in a group is “pooling risk.”<br />

An HMO has arrangements with<br />

“network.” The providers give the<br />
HMO a discounted rate in exchange for<br />
receiving health plan referrals. Members<br />
may only see physicians in this network,<br />
otherwise the costs are not be covered<br />
by the plan. Members select a primary<br />
care physician (PCP), often called a<br />
“gatekeeper,” who provides, arranges,<br />
coordinates, and authorizes all aspects<br />
of the member’s health care.<br />
Often the primary care physician (PCP)<br />
in an HMO plan must approve specialist<br />
and ancillary service referrals as well as<br />
coordinate the member’s care.<br />
PPOs are similar to HMOs in that they<br />
have arrangements with a “provider<br />
network.” Unlike an HMO, members<br />
may choose a doctor outside of this<br />
network, but their coverage will be at a<br />

Since she has a preexisting condition of rheumatoid arthritis for which she takes<br />
expensive medication, an individual plan may be difficult for her to obtain. As<br />
such, employer-sponsored health insurance would be best. The best way to keep<br />
her own doctor would likely be through a PPO, where she could go out of the<br />

High prevalence of disease will increase<br />
the PPV and decrease the NPV of a test.<br />
Low prevalence will decrease the PPV<br />

A prospective cohort study evaluates a<br />
cohort of individuals after they have<br />
experienced the risk factor/exposure,<br />
but before development of disease/<br />

evaluate whether children exposed to<br />
secondhand smoke at birth will be more<br />
susceptible to lung cancer than those<br />
children not exposed, started when<br />
children are 5 years old).<br />
A retrospective cohort study evaluates a<br />
cohort of individuals after both the risk<br />
factor/exposure and the disease/outcome<br />
have happened. (Eg, a study of if children<br />
exposed to secondhand smoke at birth<br />

What is relative risk (RR)?<br />
How is RR calculated?<br />
RR is a measure of the likelihood of<br />
disease in exposed subjects compared<br />
to unexposed. It is expressed as a ratio,<br />
so an RR = 1.0 is the risk of the<br />
unexposed subjects.<br />
It is the incidence of disease in the<br />
exposed group divided by the incidence<br />
of disease in the unexposed group.<br />
RR = [a/(a + b)]/[c/(c + d)]<br />

CLINICAL VIGNETTES<br />
How have advances in antiretroviral therapies influenced the prevalence of HIV,<br />
assuming incidence of HIV has remained constant?<br />
HIV has an increased prevalence due to the lengthening of life expectancy of<br />
infected patients. Using P = I × D, and assuming the medications have little effect<br />
on incidence, as duration is increased, so is prevalence. (Note that HAART does<br />
significantly decrease the transmission of HIV.)<br />
If you are told that almost all children with chickenpox have a fever, but that fever<br />
can be a feature of many illnesses. How would you describe fever in terms of<br />
sensitivity and specificity in regards to chickenpox?<br />
Sensitivity would be high (someone without fever would be unlikely to have<br />
chickenpox), specificity would be low (fever could be from many diseases).
Epidemiology and Research Design 207<br />
Two groups of male patients are looked at over a 10-year period, ones that like to<br />
go to the doctor regularly for checkups and ones that don’t get much care at all. It<br />
is found that the group which goes to the doctor regularly has a longer survival<br />
time after diagnosis of prostate cancer than the ones who don’t get much care.<br />
What type of study design is this? What type of measure of risk would you use to<br />
compare the groups? What is a likely potential type of bias in this study?<br />
This is a cohort study—it separates groups based on the risk factor/exposure of<br />
health-care utilization and then monitors for the development of disease and<br />
death. Cohort studies use relative risk measures (as opposed to case-control<br />
studies which use odds ratios). This study likely suffers from lead time bias as the<br />
survival time after diagnosis is directly dependent on how early a patient is<br />
screened for disease—likely more often for those going to the doctor regularly.<br />
A new laboratory test for depression is developed. Nearly 2500 patients are tested,<br />
800 with depression and 1700 without depression. There are 720 true positives,<br />
1500 true negatives, 80 false negatives, and 200 false positives. What is the<br />
sensitivity of test? What is the specificity of the test? If a patient from this same<br />
population tests positive for depression, how certain are you that the patient<br />
actually has depression? How about if the same patient tested negative—how sure<br />
are you that he/she doesn’t have depression?<br />
First off, make a four-box diagram, as done below. You should start with this every<br />
time. The bold numbers are row and column totals. Remember that a is true<br />
positives, b is false positives, c is false negatives, and d is true negatives.<br />

For the first two questions, plug in numbers. Sensitivity = 720/(80 + 720) = 90%.<br />
Specificity = 1500/(1500 + 200) = 88%. The second two questions are really asking<br />
you to calculate the positive predictive value and negative predictive value,<br />
respectively. PPV = 720/(720 + 200) = 78%. NPV = 1500/(1500 + 1580) = 95%.

effect in your research study?<br />
Which would be true if there were an<br />
effect in your research study?<br />
What is a type I (α) error?<br />
What is a type II (β) error?<br />
What is power?<br />
The idea that, by default, there are no<br />
relationships between variables. Research<br />
must then be done to disprove this—<br />
called “rejecting the null.”<br />
A hypothesis stating that there is no<br />
difference between an experimental<br />
and control group. (ie, variables are<br />
unrelated)<br />
A hypothesis stating a relationship<br />
between variables, or an effect on an<br />
experimental group different than the<br />
control group. If this was true, you<br />
would “reject the null.”<br />
You would accept the null hypothesis.<br />
You would reject the null hypothesis.<br />
A type I error rejects the null when the<br />
null is actually correct—this type of<br />
error says there is an effect when there<br />
actually is not. A “False-Positive.”<br />
Related to p-value.<br />
A type II error does not reject the null<br />
when the alternative hypothesis is<br />
actually correct—this type of error does<br />
not detect an effect when there actually<br />
is one. A “False-Negative.”<br />
It is the probability of rejecting the null<br />
hypothesis when it is indeed incorrect.<br />
This is the study’s ability to detect an<br />
effect, if present.

That the probability of an observed<br />
effect being due solely to chance is low<br />
enough that the effect is likely true.<br />
It is the percent chance that an effect<br />
seen between variables or in an<br />
experimental group was due to chance<br />
alone. For example, if p = 0.25, there is a<br />
