Autism is a disorder of neural development characterized by impaired social interaction and communication, and by restricted and repetitive behaviour.Autism is a developmental disorder that appears in the first 3 years of life, and affects the brain’s normal development of social and communication skills.Autism is a physical condition linked to abnormal biology and chemistry in the brain. The exact causes of these abnormalities remain unknown, but this is a very active area of research. There are probably combinations of factors that lead to autism.

People with autism have issues with non-verbal communication, a wide range of social interactions, and activities that include an element of play and/or banter.
