Autism is a developmental disorder of the brain that appears in early childhood. The
condition causes impairment of social interaction and communication, as well as unusual
behaviors.
What are the symptoms of autism? Symptoms vary but are
characterized by a difficulty in relating to people, objects, and events. Communication
problems may be present, such as a lack of eye contact or response when their name is called;
fixation on specific subjects or toys; difficulty with changes to routine or surroundings; and
repetitive body movements, such as head banging or hand flapping.
How is it treated? There is no established conventional
treatment for autism. Therapy generally consists of using medications, such as antidepressants, stimulants, and antipsychotics, to manage
symptoms of associated disorders, which include attention
deficit, hyperactivity, obsessions, compulsions, tics, irritability, seizures, and depression.
Dietary changes that may be helpful: Preliminary research
suggests that some autistic children may be allergic or
sensitive to certain foods and that removal of these foods from the diet has appeared to
improve some behaviors.1 As a result, one prominent doctor has recommended a trial
hypoallergenic diet.2 Such a trial
requires supervision by a doctor.
Nutritional supplements that may be helpful: Uncontrolled and
double-blind research shows that vitamin B6 can be
helpful for autistic children.3 4 5 In these trials, children
typically took between 3.5 mg and almost 100 mg of B6 for every 2.2 pounds of body weight,
with some researchers recommending 30 mg per 2.2 pounds of body weight. Although toxicity was
not reported, such amounts are widely considered to have potential toxicity that can damage
the nervous system; these amounts should only be administered by a doctor. One prominent
researcher has suggested that vitamin B6 is better supported by research than is drug
treatment in dealing with autism.6
Some researchers have added magnesium to vitamin B6,
reporting that taking both nutrients may have better effects than taking B6 alone.7
The amount of magnesium—10 to 15 mg per 2.2 pounds of body weight—is high enough
to cause diarrhea in some people and should be
administered by a doctor. Doctors will often try vitamin B6 or the combination of B6 and
magnesium for at least three months to see whether these nutrients help autistic children.
In one double-blind trial lasting ten weeks, autistic children given 1 gram vitamin C for each 20 pounds of body weight showed a reduction in
symptom severity compared with placebo.8 The authors speculate that vitamin C may
play a positive role because of its known effects on a hormone pathway typically disturbed in
children with autism.
Are there any side effects or interactions? Refer to the individual supplement for
information about any side effects or interactions.
