The wealth of information now available on depression is enormous, but has not been summarized into a comprehensive encyclopedia until now.The entries in this book include: behavioral treatment, cognitive theories, cognitive therapy, epidemiology, heredity, personality disorders, double depression, and prevention. In summarizing the vast amount of information on depression, ""The International Encyclopedia of Depression"" serves as an important resource for researchers, patients, students, and educated laypeople. This book presents holistic, interdisciplinary coverage of an important but misunderstood medical disorder.
