Throughout eight prior editions, CTP has been established as the cornerstone text in the field of psychiatry and mental health. This Ninth Edition provides a wealth of new and updated information in neural science, genetics, neuropsychiatry, psychopharmacotherapy, and other key areas. A distinguished new co-editor, Pedro Ruiz, MD, has joined Drs. Benjamin and Virginia Sadock for this edition, and over 500 contributors provide the most up-to-date information in every area of psychiatry and mental health. The book includes case histories, the most current DSM-IV-TR criteria and tables, and up-to-date comparative classification codes from ICD-10. A companion Website will offer the fully searchable text.
