No one knows the cause (or more likely, the multiple causes) of autism. Research is being conducted in many areas to determine the cause of autism or the causes of the symptoms exhibited by those who have autism.

While there is no known specific cause of autism, there is some understanding of the reasons for some of the symptoms.

Regardless of causation, we do know that autism is a neurobiological disorder – it is not caused by bad parenting or trauma. We also know that many of autism’s core symptoms can be ameliorated through education, intervention and other therapeutic programs.
