Causes of autism

Features of autism
How autism can be treated

There is no single cause of autism.

Studies on autistic people, still in progress, have highlighted anomalies in brain structure, leading to the conclusion that

autism is caused by damage to normal brain development at an early stage of the fetal development.

Researchers also point to the possibility of

• genes

• environmental factors (such as viruses or chemicals)  

being contributory to the disorder.
