Johns Hopkins latest research on the causes of autism

This is an interesting article about a possible cause of autism. As the article states, maternal antibodies have been linked to autistic babies, but are likely not the direct cause of autism. I find this kind of research so fascinating, because there has been so much research into the causes of autism and still no real answers.
