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…

TLDR
Differences in the presence and degree of basic clinical characteristics represent the spectrum of autism disorders.
What’s new in autism?
This review on autism spectrum disorder (ASD) focusses on recent insights in the clinical picture, such as continuity of the phenotype and the concept of broader phenotype, on epidemiology and on

TLDR
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.
Examination of Group Differences using the Autism Spectrum Disorders-Diagnostic for Children (ASD-DC)
The diagnosis of autism spectrum disorders (ASD) has become more critical with the recognition that early and ongoing treatment is essential. Furthermore, differentiating severity of symptoms within
Factor Structure of the Autism Spectrum Disorders-Diagnostic for Children (ASD-DC)
This investigation consisted of two studies designed to look at the underlying structure of the Autism Spectrum Disorders-Diagnostic for Children (ASD-DC). Study 1 was a factor analysis of the
Using the Childhood Autism Rating Scale to Diagnose Autism Spectrum Disorders
TLDR
Results confirm the utility of the CARS in distinguishing autistic disorder from PDD-NOS, and distinguishing ASD from other developmental disorders and typical development and suggest that an ASD cutoff around 25, which is in common clinical use, is valid.

TLDR
Specific detailed recommendations for each level have been established in this document, which are intended to improve the rate of early suspicion and diagnosis of, and therefore early intervention for, autism.

TLDR
The factors that influence the presence of depression in persons with autism, such as the level of intelligence, age, gender, associated medical conditions, and the role of genetic factors and life events are examined.

TLDR
The historical development of the classification of PDD is reviewed, recent empirical data on issues of reliability and validity are summarized, and a new approach to classification and understanding is suggested.
Epilepsy in autism
The prevalence of autism.
TLDR
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.
TLDR
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.

TLDR
It is concluded from the review of the evidence that, in the absence of additional, more compelling data, the clinical usefulness of existing screening instruments remains questionable.
Prevalence of Childhood Disintegrative Disorder
TLDR
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.
