Peggy Halliday discusses a variety of topics related to autism spectrum disorders, such as what causes autism
Host: What causes autism? Peggy Halliday: No one knows what causes autism. This is an area of a great amount of research in the medical field today. There are a number of theories that are being checked out but we really don't know what causes autism. We know that researchers agree that there is some kind of genetic link and we know that at least in some children with autism environmental factors probably play a role as well. Originally, autism was found to be caused by cold, unfeeling mothers. We know that this is absolutely untrue. Whatever the causes, we know that it is present either at birth or the likelihood to develop autism is present at a child's birth.
