What is Autism?

autismCameron is an angelic four-year-old with tumbling black curls and gorgeous blue eyes. Because of his striking looks he attracts more than his fair share of attention from passers-by, but the majority of them come away from an encounter with Cameron with a sense of frustration. He refuses to make eye-contact, shies away from conversation, and seldom responds even to the requests of his mother.

His language skills are below par and he appears to lack the usual broad emotional range characteristic of his age. He avoids first-person pronouns in his speech: if asked does he want a cookie, Cameron will reply: "He wants a cookie". He usually resists being hugged, even by his parents and grandparents. Cameron suffers from autism.

Autism is a relatively rare disorder. Figures vary, but the American Psychiatric Association estimate about two per 1,000 births. Gender differences in the incidence of autism are marked, and depend on the IQ of the individual. For those with very low IQs, the trend is towards a higher female population. Autistic children with average-to-high IQs are typically male. There is a varying range in IQ for suffers of this disorder: about half of identified autistic children have IQs in the severe mental retardation range (<50), around a quarter have IQs in the 50 to 70 range, with the remainder in the borderline to average range (average being 100 IQ points). Naturally, those displaying lower IQ scores are more likely to be delayed in communication skills and need intensive educational and emotional support during the course of their life. Despite these grim statistics, there are autistic children who grow up to be accomplished adults, a small percentage with university degrees and productive employment. There remain, however, difficulties in social interaction.

Autistic disorder is a worldwide phenomenon, and is independent of race or culture. However, the majority of children with autism will display the unmistakable signs of the disorder by an average age of 36 months. Autism is a complex and puzzling disorder and researchers have presented numerous theories over the years to explain it.

In later articles, we will be looking at the symptoms and theories of autism, and its close cousin, Asperger's Disorder.

Thank you for this. I have a son with Asperger's Syndrome. Everyone thinks I am a terrible parent because my son looks normal but is hyperactive and throws tantrums. I suffered with my own load of guilt until his doctor reassured me that I can do nothing to stop this cycle but get professional help.

I believe that Autism is much more prevalent than indicated here. According to the Autism Society of America, Autism occurs in 1 in 166 children. This is a huge increase since my son (now almost 28 years old) began to show characteristics of the condition. When he was 3 years old, the risk was 1 in 10,000.

These figures have been quoted from the American Psychiatric Association and it's important to remember two things: the AS disorders are better understood than they were 30 years ago (in fact Asperger's as a condition did not formally exist) and, most importantly, autism and especially Asperger's have unfortunately become "buzz" conditions, much like ADHD did in the 90s. Misdiagnosis of "new" diseases, especially when drug companies release a new drug targeting the condition, invariably result in increased numbers of sufferers. The APA publishes more conservative, more accurate and better researched statistics.
