About Autism

What is autism?

This deceptively simple question is a huge part of the problem. Today, “autistic disorder” is considered a psychiatric diagnosis in the Diagnostic and Statistical Manual of Mental Disorders (“DSM-IV”), the standard reference for the classification. The diagnostic criteria, included below, include (1) impairments in social interaction, (2) impairments in verbal and non-verbal communication, and (3) stereotypical restricted or repetitive patterns of behavior and interests. There are no universally accepted biomarkers such as physical characteristics or blood or urine tests. The three domains of diagnostic criteria for autistic disorder cover a wide spectrum, from individuals with no language, almost no social interaction and severe behavioral problems, to extremely high-functioning individuals with intense interests and quirky personalities. The range of autism spectrum disorders formally includes autism, Rett’s Disorder, Childhood Disintegrative Disorder, Asperger’s Syndrome, and Pervasive Development Disorder Not Otherwise Specified (PDD-NOS).
