Autism spectrum disorders (ASDs) are complex neurodevelopmental disorders characterized by qualitative impairments in three domains: social interaction, communication, and repetitive, stereotyped behaviour. ASDs can have a negative impact on the well-being of affected individuals*. These symptoms often begin by the age of three years, and persist throughout the life span.
Autism is often referred to as a “spectrum disorder,” meaning that its symptoms and characteristics can present themselves in a variety of combinations, ranging from mild to quite severe.
The phrase “Autism Spectrum Disorders (ASD)” refers to a broad definition of autism including the classical form of the disorder as well as Pervasive Developmental Disorder Not Otherwise Specified (PDDNOS), Rett syndrome, Asperger syndrome, and Childhood Disintegrative Disorder.
Autism Facts & Statistics*
- Autism now affects 1 in 88 children.
- Boys are four times more likely to have autism than girls.
