What are the causes?

There is no confirmed single cause for ASD, but it is generally accepted that causes include abnormalities that may be there brain structure or function. Brain scans show differences in the shape and also a structure of the brain in children having autism compared to that in neurotypical children.

In many families, there appears to be a pattern of autism or other related disabilities, thus supporting the theory that this disorder may have a genetic basis. While no single gene has been discovered as causing autism, researchers continue to search for irregular segments of genetic code that children having autism may have inherited. It even appears that some children are born with a susceptibility to having autism, but researchers have not yet identified any “trigger” that causes autism to develop.
