This seventh edition of Basic Child Psychiatry has been thoroughly revised to take account of advances in a rapidly changing area of medicine. An increased understanding of the role of genetic factors and the use of new diagnostic techniques, including modern brain imaging procedures, are providing new information about the aetiology of child psychiatric disorders. These, and new developments in epidemiology and treatment methods are fully reflected in this new edition. As in previous editions, extensive references are provided so that readers can readily obtain access to additional information. Like earlier editions, this one is a model of clear, uncluttered writing and will be of value to all who have a professional interest in the psychiatric disorders of childhood and adolescence.
