Writing in clear, conversational prose, Benaron (medical director, Far Northern Regional Center, Redding, CA) leads readers along a difficult path: she tries to make sense of the complicated disorder of autism. The route is confounded at many junctures: debates about labeling and classification systems; variable diagnostic evaluations; the mystery of what causes autism; lack of agreement on the part of professionals about acceptable treatments (both traditional and alternative); lack of knowledge about predicting long-term outcomes for specific individuals… Benaron manages a fair and thorough description of the disorder and the direction of the future work on it. This is an excellent library and classroom resource for those new to autism and for those looking for a recent update of knowledge on the subject. Recommended. Lower-and upper level undergraduates; general readers.'
