Studies have listed several causes for the disorder and have found abnormalities in several parts of the brain that are believed to have occurred during foetal development. The problem may be centered in the parts of the brain responsible for processing language and information from senses. There also appears to be a strong genetic basis for Autism. Family studies have shown that identical twins are more likely to be diagnosed with autism than twins who are fraternal (not genetically identical).
