Five researchers in Italy have proposed a comprehensive hypothesis for the etiology of the autism epidemic.
First, I want to tell readers why I think the incidence of autism is actually increasing and that the increased incidence is not just due to better recognition. Autism is not a subtle disease; it is not easily missed. The children usually do not speak or have impaired verbal communication. They rarely have a single friend. They frequently perform repetitive behaviors, and they often fly into rages over a little change in their routine. There is nothing subtle about autism.
