of string or cloth may festoon jackets or shirts. Patients may<br />

cut off their eyebrows or make deep gashes in their arms or<br />

legs. Some seem almost analgesic: one patient bit out part of<br />

his biceps muscle; another eviscerated himself, ‘just to see’<br />

what was inside. In some cases the bizarre behavior may be<br />

in response to delusions, as, for example, when a patient<br />

wrapped his legs in aluminum foil to ‘keep the bugs off’.<br />

NEGATIVE SYMPTOMS<br />

‘Negative’, or ‘defect’, symptoms (Andreasen 1982;<br />

Andreasen and Olson 1982; Andreasen et al. 1990a)<br />

include flattening of affect, poverty of thought or speech,<br />

and avolition.<br />

Flattening of affect, also known as mere ‘blunting’ of<br />

affect when less severe, is, as discussed further in Section<br />

4.25, characterized by a lifeless and wooden facial expression<br />

accompanied by a corresponding dearth or diminution<br />

of all feelings.<br />

Poverty of speech and poverty of thought are often<br />

referred to collectively as ‘alogia’. Poverty of speech is said<br />

to be present when patients, although speaking a normal<br />

amount, seem to ‘say’ very little; there is a dearth of meaningful<br />

content and speech is often composed of stock<br />

phrases. In poverty of thought, by contrast, patients speak<br />

little, essentially because there is a wide-ranging and farreaching<br />

impoverishment of their entire thinking; patients<br />

may complain that their heads are ‘empty’ and that, simply,<br />

nothing comes to mind; there are no stirrings.<br />

Avolition, referred to by Kraepelin as ‘annihilation of<br />

the will’, is allied to poverty of thought in that avolitional<br />

patients simply do not experience any impulses, desires,<br />

stirrings or inclinations; if left undisturbed they may spend<br />

hours or days in quietude, doing nothing.<br />

MISCELLANEOUS SYMPTOMS<br />

Of the miscellaneous symptoms seen in schizophrenia, perhaps<br />

the most important are transient disturbances of<br />

mood, which may tend toward depression, mania, or anxiety.<br />

Patients may complain of depressive symptoms, such as<br />

feeling depressed, being tired or having trouble sleeping;<br />

some may demonstrate some euphoria and increased energy<br />

and talkativeness, whereas others may complain of feeling<br />

anxious and tremulous. Indeed, at first glance these symptoms<br />

may seem to dominate the clinical picture; however,<br />

on a closer and wider look one finds that they are transient,<br />

lasting only hours or days, are mild overall, and, relative to<br />

other symptoms, such as hallucinations and delusions, play<br />

only a very minor role in the overall clinical picture.<br />

Agitation may also be seen, and this may occur either as a<br />

non-specific part of an exacerbation of the disease or as a<br />

reaction to delusions of persecution or threatening voices.<br />

SUBTYPES<br />

Classifying patients as to subtype is useful not only because<br />

the various subtypes pursue different courses with different<br />

20.1 Schizophrenia 609<br />

prognoses, as noted further below, but also because knowledge<br />

of a patient’s subtype diagnosis may allow the clinician<br />

to predict how the patient will act in any given situation.<br />

After discussing the paranoid, catatonic, disorganized,<br />

simple, and undifferentiated subtypes of schizophrenia,<br />

some comments will also be offered on an alternative<br />

mode of subdividing schizophrenia, namely into ‘reactive’<br />

and ‘process’ types.<br />

Paranoid schizophrenia tends to have a somewhat later<br />

onset, sometimes as late as in middle years, and is characterized<br />

primarily by hallucinations and delusions; disorganized<br />

speech, catatonic or bizarre behavior, and<br />

negative symptoms are either absent or relatively minor.<br />

Hallucinations are generally auditory and delusions are<br />

generally of persecution and reference. In paranoid schizophrenia,<br />

more so than in any other subtype, the delusions<br />

tend to be systematized and, on first glance, even plausible.<br />

Voices may warn patients that their supervisors are plotting<br />

against them. Patients may begin to suspect that people are<br />

talking about them, perhaps laughing at them behind their<br />

backs. Newspaper headlines pertain to them; the CIA may<br />

be involved or perhaps the FBI. At times patients may<br />

appeal to the authorities for help, but often they suffer their<br />

persecutions in rigid silence; occasionally they may try to<br />

escape, perhaps by moving to another area, or they may<br />

turn on their supposed attackers, sometimes violently.<br />

Often, allied with delusions of persecution, there may also<br />

be delusions of grandeur. Patients believe that they are<br />

being persecuted not for some trivial reason; they suspect<br />

that others know that they have developed great inventions.<br />

Rarely, grandiose delusions may be more prominent than<br />

persecutory ones, and they may even dominate the clinical<br />

picture. One patient believed himself to be the anointed of<br />

God; he heard trumpets proclaiming his advent and was<br />

prepared to announce himself to the world.<br />

Catatonic schizophrenia, as the name obviously indicates,<br />

is dominated by catatonic symptoms. As described in<br />

Section 3.11, catatonia occurs in both stuporous and<br />

excited forms and, although some patients with catatonic<br />

schizophrenia may demonstrate only one form throughout<br />

the course of the illness, in most cases, as noted earlier,<br />

these two forms are seen to alternate in the same patient.<br />

The duration of these forms is quite variable, ranging from<br />

hours on one extreme to months or years on the other. The<br />

transition from one form to another may be quite unpredictable<br />

and, at times, quite sudden; in one case a chronically<br />

stuporous patient, without any warning, suddenly<br />

jumped from his bed, screamed incoherently, and paced<br />

agitatedly from one wall to another, only to lapse into<br />

immobility and muteness an hour later.<br />

Disorganized schizophrenia, also known classically as<br />

hebephrenic schizophrenia, tends to have an earlier onset<br />

than the other subtypes and to develop very slowly.<br />

Although hallucinations and delusions are present, they<br />

generally play a minor role and the clinical picture is dominated<br />

by disorganized speech and bizarre behavior. Overall,<br />

the behavior of these patients seems at times to represent a
