In this paper, we give an overview of the diagnostic categories of autism and other pervasive developmental disorders (PDDs) and discuss the changes in the DSM classification system over the past 20 years. We describe each subtype of PDD, along with comorbid psychiatric conditions, assessment guidelines, and tools for diagnosis. The epidemiology of autism has generated much discussion and research; we report the most recent data, as well as recent findings about controversial issues purporting…

It is proposed that a close working relationship between neurobiologists and clinicians is necessary in order to identify etiologically based diagnostic schemas that would complement, rather than replace, the clinical diagnosis of autism.

The prevalence of autism.

The findings of a survey that found a rate of 34 per 10000 for autism spectrum disorders (ASDs) among 3to 10-year-old children in metropolitan Atlanta suggest that these differences might reflect new diagnostic criteria for autism and increased availability of developmental disability services for children with autism in the 1990s.

Comorbid association of autism and schizophrenia.

It does not appear that the two conditions are more commonly observed together than would be expected on a chance basis; therefore, the current (DSM-III-R) approach to dual diagnosis of these conditions appears reasonable.

Prevalence of Childhood Disintegrative Disorder

The conclusion is that CDD is very rare and its prevalence is 60 times less than that for autistic disorder, assuming a prevalence of 10 per 10,000 for autism.
