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. Read
about the role of environmental risk factors in Psychiatric News
at http://pn.psychiatryonline.org/content/46/16/16.2.full. 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
