Autism Spectrum Disorders (ASDs)
Autism – A Succinct Description
Autism is a complex developmental disability that causes problems with social interaction and communication. Symptoms usually start before age three and can cause delays or problems in many different skills that develop from infancy to adulthood.
Autism – A Spectrum Disorder
Different people with autism can have very different symptoms. Health care providers think of autism as a “spectrum” disorder, a group of disorders with similar features. One person may have mild symptoms, while another may have serious symptoms. But they both have an autism spectrum disorder. The autism spectrum disorder includes (1) the autistic disorder known as autism, (2) Asperger Syndrome, and (3) Pervasive Developmental Disorder or atypical autism. Sometimes health
Providers are using the broader term, pervasive developmental disorder, to describe autism. In that case this category (PDD) includes the autism spectrum disorders as well as something called Childhood Disintegrative Disorder and Rett syndrome. In most material autism spectrum disorder and “autism” mean the same thing.
