This comprehensive textbook of autism spectrum disorders is designed to meet the growing need for cutting-edge research and treatment information for clinicians who encounter patients and clients with these disorders in their practice psychiatrists, psychologists, social workers, speech therapists, and educators and for parents who seek to understand their children s disorders and treatment options. The editors have assembled foremost clinical experts in autism spectrum disorders, as well as in genetics, pharmacology, pathophysiology, neurology, neuroimaging, and other fields that contribute to our understanding of these complex disorders.

By so doing, the editors hope to establish a benchmark for understanding autism on a number of levels, with knowledge that is both broad and deep. More patients are diagnosed with autism spectrum disorders, and at earlier ages, than ever before, and these patients and their families receive services in increasingly diverse settings. Destined to become a classic, Textbook of Autism Spectrum Disorders is the volume for which patients, families, and clinicians have been waiting.
