What is Autism?


Autism is a spectrum disorder

Autism is a complex condition that affects brain development and results in differences in social interaction, communication, interests and behaviour.

Autism is not caused by parents or the way a child is raised. Research is being done to explore the possible causes of autism.

With support, people who have autism can develop their capabilities and enjoy success.
