NEW DEVELOPMENTS IN PHARMACOTHERAPY FOR AUTISM<br />

by Dr. James O’Hanlon, Psychopharmacologist<br />

Research for developing safer and more<br />

effective treatments for developmental<br />

disorders is a constant, ongoing process.<br />

Current treatments were mainly developed<br />

to minimize disruptive symptoms<br />

but in the future a better understanding<br />

of innate deficits should lead to treatments<br />

that increase individual abilities.<br />

Emerging trends in research for achieving<br />

this goal are apparent in the list of ongoing clinical trials provided by<br />

National Institutes of Health (NIH) at their website, www.Clinical<strong>Tri</strong>als.<br />

gov. The list, stratified by sponsor, disorder and intervention, includes<br />

all federally funded clinical trials and most supported privately in the<br />

USA with a smattering of those in progress elsewhere. <strong>Tri</strong>als concerned<br />

with autism have quadrupled over the last five years until now, 132 are<br />

in progress or completed but not yet reported. Most (74%) deal with<br />

testing the efficacy of particular treatments:<br />

• Pharmacological (42%)<br />

• Behavioral (10%)<br />

• Dietary restrictions or supplements (8%)<br />

• Acupuncture/acupressure (5%)<br />

• Hyperbaric oxygen (4%)<br />

• Other (5%)<br />

Pharmacological trials may be further divided between the majority<br />

dealing with well-established drugs like Risperdal and Prozac and a<br />

minority concerning novel agents that have shown promise in preliminary<br />

studies. Some among the latter may emerge as pharmacotherapy<br />

of the future and are discussed here for that reason.<br />

SOME INNOVATIVE STRATEGIES<br />

MINOCYCLINE<br />

There is evidence that an innate neuroimmune<br />

reaction causes chronic inflammation in the<br />

autistic brain. Investigators at National Institute<br />

of Mental Health (NIMH) are currently testing<br />

the effects of minocycline, an antibiotic with<br />

strong anti-inflammatory properties, in children<br />

with autism with the hope of achieving<br />

global behavioral improvement.<br />

INTRANASAL OXYTOCIN<br />

Intranasal oxytocin is being administered to<br />

children with autism in a trial at Mount Sinai<br />

School of Medicine. Oxytocin is a naturally<br />

occurring brain hormone that promotes social<br />

bonding in all mammalian species and a<br />

pilot study suggested that it might have the<br />

same effect in autism.<br />

D-CYCLOSERINE<br />

D-cycloserine was developed for treating<br />

tuberculosis. Then it was discovered that the<br />

drug attenuates excitatory neurotransmission<br />

in the brain. Preliminary studies have shown<br />

its benefit in schizophrenia and also autism<br />

where it reduced social withdrawal. Two trials<br />

with d-cycloserine, led by world-class experts<br />

in autism, Drs. David Posey and Chris Mc-<br />

Dougle, are underway at Indiana University.<br />

N-ACETYLCYSTEINE<br />

Posey and McDougle are also conducting<br />

a study with N-acetylcysteine (NAC), which<br />

increases glutathione, the body’s primary<br />

defense against toxic free radicals (‘oxidative<br />

stress’). The causes, effects and extent of<br />

oxidative stress in the autistic population are<br />

a matter of hot debate but there is reasonable<br />

evidence that it causes immune abnormalities,<br />

associated with deficient glutathione, in<br />

a sizable proportion.<br />

ARICEPT, RAZADYNE AND EXELON<br />

Drugs that increase the acetylcholine neurotransmission in the brain by inhibiting the enzyme<br />

that inactivates the transmitter – Aricept, Razadyne and Exelon – are 1st-line therapy for Alzheimer’s<br />

disease. Small scale studies with each of the drugs have provided an indication that they improve<br />

receptive and expressive language in children with either autism or Down syndrome. The<br />

manufacturer of Aricept has now launched an extensive trial series with the apparent purpose of<br />

registering the drug for the indication of cognitive dysfunction in children with Down syndrome.<br />

Controlled trials with Aricept and Razadyne for autism are also being conducted at NIMH and the<br />

University of Medicine, New Jersey, respectively.<br />

PERSON CENTERED THINKING<br />

TRAINING<br />

“Introduction to Person Centered<br />

Thinking” is a 10-hour training that<br />

teaches a set of ideas, skills and<br />

strategies to assist individuals who<br />

use services to achieve greater control<br />

and influence over their lives leading<br />

to positive community participation<br />

and value. There are several upcoming<br />

opportunities to attend this<br />

training. Trainings are hosted by<br />

different agencies and all trainers use<br />

a standard curriculum that has been<br />

approved by the Learning Community<br />

for Person Centered Practices.<br />
