Harris' Developmental Neuropsychiatry: The Interface with Cognitive and Social Neuroscience provides updated information to the first edition which was awarded Dewey's Medical Book of the Year. The outcome of many discussions with faculty members, residents, medical students, and nonmedical professionals over the past three decades at the Johns Hopkins Medical Institution, Harvard Medical School, and McLean Hospital, this revamped second edition provides a comprehensive summary of knowledge and literature acquired through the authors' work with children and adolescents with developmental disorders and their families. This second edition features new material including epigenetics, social and affective neuroscience, updated DSM definitions and criteria for specific disorders, as well as all the latest genetics from the past 15 years. Harris' Developmental Neurospychiatry will be an invaluable resource for medical and graduate students.
