Over one million children and adolescents in the US suffer from Obsessive-Compulsive Disorder (OCD), a baffling illness that can be debilitating for the child in school, with friends, and with family. Help is now available! Cognitive-Behavioral Therapy (CBT) is the gold standard of treatment for OCD and offers youngsters and their families the path to mastery over OCD. In this uniquely creative and heart-warming book, Dr. Wagner, an internationally recognized expert in the treatment of childhood OCD, uses the powerful real-life metaphor of the Worry Hill to describe OCD and its treatment clearly and simply through the eyes of a child. Children and adults will identify with Casey's struggle with OCD, his sense of hope when he learns about treatment, his relief that neither he nor his parents are to blame, and eventually, his victory over OCD. Parents and Professionals can use this book alone or together with the companion book, What to do when your Child has Obsessive-Compulsive Disorder. This is the only children's OCD book that has a companion book for parents.
