Why is there so many conditions connected with autism/aspergers ?

Interesting question: I'm not sure there is a good answer to your question. We have been learning more and more about Autism Spectrum Disorders, but there is still a lot to learn. The diagnosis has been evolving over the years, so it's difficult to know if everyone is talking about the same thing. It is clear that vaccines are NOT the cause of ASD problems- this has been studied quite extensively.
