Understanding the Nature of Autism and Asperger's Disorder is 'a consultation with Prof. Ritvo' - a thoroughly accessible introduction for professionals, families, spouses and individuals with autism and Asperger's Disorder. Prof. Ritvo traces the historical development of understanding about autism and Asperger's Disorder, from the centuries of misdiagnoses and the first recognition of the characteristics of the disorders to his own highly-regarded methods for making a diagnosis. Drawing on case histories from forty years' of clinical practice, he explains their basic nature, what the causes are, what is different in the brain, treatments that work (and those that don't), what a child with a diagnosis might be like when he or she grows up, and what future research may hold.

This book will be an absolute must-read for anyone with an interest in autism and Asperger's Disorder, whether a practitioner, a parent, a student, or an affected individual.
