As soldiers and combat veterans have returned from the wars in Iraq and Afghanistan traumatic brain injury (TBI) has been identified as the signature injury of those wars. This new edition of Textbook of Traumatic Brain Injury has been thoroughly revised and updated from the 2005 first edition to reflect the exponential expansion of research and clinical data amassed in the intervening years. Each chapter was written and reviewed by the foremost authorities in neuropsychiatry, neurology, rehabilitation medicine, and the other specialties who assess, diagnose, and treat these patients. This textbook addresses epidemiology and pathophysiology; neuropsychiatric disorders; neuropsychiatric symptomatologies; special populations and issues; and treatment. Many of the foremost scholars and clinicians who contributed to the previous edition are back with revisions of their chapters, and the volume also features five new chapters on such timely and critical topics as posttraumatic stress disorder, TBI in the context of war, and epidemiology in military and civilian populations. Textbook of Traumatic Brain Injury has been crafted to be both comprehensive and readable and to serve as a primary resource for clinicians understanding, assessment, and treatment of patients and their families who suffer from TBI.
