What is autism?

Autism spectrum disorder (ASD) is a condition that affects social interaction, communication, interests and behaviour. It includes Asperger syndrome and childhood autism.

What causes autism?

The causes of ASD can be described in two ways:

• Primary ASD (also known as idiopathic ASD) ? where no underlying factors can be identified to explain why ASD has developed.
• Secondary ASD ? where an underlying medical condition or environmental factor thought to increase the risk of ASD is identified.

Should the causes’ of autism be studied in order for people to have a better understanding of why, either themselves or their child has the disorder?

Is there enough support for people who have autism?
