Autism Spectrum Disorder

Autism Spectrum Disorder (also called Autism Spectrum Conditions) is a neurodevelopmental disorder characterized by difficulties with communication, social interaction and can be associated with unusual behavior such as very restricted interests and highly repetitive behavior (i.e. arranging objects in stacks or lines, hand flapping, body rocking). The term "spectrum" refers to the fact that symptoms can range from mild to severe, depending on each individual.

There are five types of Autism Spectrum Disorders. The three most common types include:

  • Autistic Disorder (AD) is associated with deficits in verbal and non-verbal communication and social understanding, cognitive impairments, and unusual behaviors.
  • Asperger’s Syndrome is characterized by impairments of varying severity in social interaction and understanding, as well as restricted and repetitive activities and interests. Language and cognitive development are less severely affected, and may be normal or even advanced.
  • Pervasive Developmental Disorder Not Otherwise Specified (PDD-NOS), also known as atypical autism, is characterized by varying degrees of impairment in social interaction, and/or restricted activities and interests. However, the strict criteria for autistic disorder are not met.

Recent research shows a genetic link to Autism.
