“Demitri and Janice Papolos have broken important new ground by taking on the challenging problem of bipolar (manic-depressive) disorder in children and adolescents. The disorder is much more prevalent than has traditionally been accepted by many mental health professionals, frequently undiagnosed or misdiagnosed, and improperly treated. This new book reviews what is known about this long overlooked, but rather common, pediatric disorder, balancing scientific and clinical knowledge with moving personal accounts of experiences of real families who have known the problems all too well, typically with too little appropriate help. Their efforts are welcome, and should help to open up a much-needed, wider consideration of pediatric bipolar disorder, its distinction from behavioral and attention disorders of youth, and the need for redoubled efforts at serious scientific study as well as clinical efforts to improve its timely recognition and long-term treatment. This book has major public health significance.”
