Presenting a comprehensive developmental approach, this book examines the origins and course of normal and pathological dissociation in children and adolescents. The volume illustrates the critical connection between pathological dissociation and trauma, and provides a clear synthesis of what is known about the psychobiology of dissociative disorders and the effects of pathological dissociation on cognition, memory, and behavior. Amply illustrated with clinical vignettes, the book describes an array of diagnostic and treatment techniques and includes reproducible copies of validated dissociation scales for all age groups.
