Autism is a lifelong development condition characterised by difficulties in social interaction, communication, restricted and repetitive interests and behaviours, and sensory sensitivities.

​

These behaviours often manifest in an intense and focused interest in a particular subject matter; stereotyped body movements like hand flapping and spinning; and an unusual and heightened sensitivity to everyday sounds or textures.

​

People on the autism spectrum experience difficulties with social interaction and impaired and unusual verbal and non-verbal communication.
