In this new, thoroughly revised and updated edition an international, interdisciplinary team of mental health experts draw together the latest findings in the psychopathology of depression in young people. Combining theory and practice, the psychological, neurochemical and genetic causes are discussed and an account of the clinical characteristics and frequency of the condition is given. The key questions are fully addressed: the importance of life events and difficulties in the onset and continuation of depression; the efficacy of current psychological therapies and the role of medication; how depressed young people progress into adult life, and how depression arises and the effects it may exert on brain and behaviour during this crucial developmental period. This book will appeal to child psychiatrists and psychologists, developmental psychologists, neuroscientists and mental health professionals in clinical services.
