This landmark book is the first comprehensive edited volume on body dysmorphic disorder (BDD), a common and severe disorder. People with BDD are preoccupied with distressing or impairing preoccupations with non-existent or slight defects in their physical appearance. People with BDD think thatthey look ugly - even monstrous - although they look normal to others. BDD often derails sufferers' lives and can lead to suicide.BDD has been described around the world since the 1800s but was virtually unknown and unstudied until only several decades ago. Since then, research on BDD has dramatically increased understanding of this often-debilitating condition. Only recently, BDD was considered untreatable, but today, mostsufferers can be successfully treated.This is the only book that provides comprehensive, in-depth, up-to-date information on BDD's clinical features, history, classification, epidemiology, morbidity, features in special populations, diagnosis and assessment, etiology and pathophysiology, treatment, and relationship to other disorders.Numerous chapters focus on cosmetic treatment, because it is frequently received but usually ineffective for BDD, which can lead to legal action and even violence toward treating clinicians. The book includes numerous clinical cases, which illustrate BDD's clinical features, its often-profoundconsequences, and recommended treatment approaches.This volume's contributors are the leading researchers and clinicians in this rapidly expanding field. Editor Katharine A. Phillips, head of the DSM-V committee on BDD, has done pioneering research on many aspects of this disorder, including its treatment.This book will be of interest to all clinicians who provide mental health treatment and to researchers in BDD, anxiety disorders, eating disorders, and other obsessive-compulsive and related disorders. It will be indispensable to surgeons, dermatologists, and other clinicians who provide cosmetictreatment. Students and trainees with an interest in psychology and mental health will also be interested in this book.This book fills a major gap in the literature by providing clinicians and researchers with cutting-edge, indispensable information on all aspects of BDD and its treatment.
