Researchers are also devoting considerable effort to the search for the roots of autism, with the goal of learning enough about the etiology to prevent some cases of autism. A new study reported in the Archives of General Psychiatry suggests that environment plays a more crucial role than previously thought and may contribute more to autism's etiology than genes do.

For an in-depth review of the etiology, diagnosis, and treatment of autism, see the Textbook of Autism Spectrum Disorders, from American Psychiatric Publishing. Information on this book is posted at http://www.appi.org/SearchCenter/Pages/SearchDetail.aspx?ItemId=62341.
