Treatment of military-related posttraumatic stress disorder is a major public health care concern. Since 2001 over 2.5 million troops have been deployed to Iraq or Afghanistan, many of whom have experienced direct combat and sustained threat. Estimates of PTSD rates related to these wars range from 8% to over 20%, or 192,000 to 480,000 individuals. Already, nearly 250,000 service members of Operations Enduring Freedom, Iraqi Freedom, and New Dawn have sought VA health care services for PTSD. This recent increased need (...) for mental health services comes in addition to the ongoing needs of Vietnam-era and other veterans who continue to suffer from PTSD. PTSD is related to high co-morbidities of other mental health difficulties, poorer physical health status, and increased medical care utilization. Such high demand for services is an important contributor to the large cost associated with combat-related PTSD. Accordingly, promoting successful, cost-effective treatment strategies for PTSD is a chief public health care priority. (shrink)

There are a number of considerations, including ethical and clinical or diagnostic factors, in utilizing the diagnosis of posttraumatic stress disorder in criminal proceedings. The reliability and validity of the diagnosis may be questioned. Legal precedent may consider extant diagnostic criteria for PTSD and comorbid diagnoses. However, these diagnostic criteria are often in flux considering new research findings. For example, the introduction of the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders, published by the American Psychiatric Association, (...) includes some changes in the PTSD diagnostic criteria. How will this affect interpretation of past legal judgments? Moreover, PTSD has significant psychiatric comorbidity, e.g., substance abuse, which in itself may influence violent behavior and its consequences. Some of these comorbid diagnoses also have changes in their diagnostic criteria. The introduction of biological tests in the assessment of PTSD will likely facilitate more objective diagnosis.
