In response to a Congressional mandate, the Department of Veterans Affairs created the National Center for Post-Traumatic Stress Disorder in 1989 "to address the needs of veterans with military-related PTSD". Over the past sixteen years, the Center has created a cornucopia of helpful resources on this subject, including fact sheets, research papers, and handbooks. Many of these items are available on this site, and will be helpful to health care professionals and those who might have a friend or loved one living with PTSD. Persons with a scholarly interest in PTSD may wish to utilize the PILOTS Database, which is the largest interdisciplinary index to the worldwide literature on traumatic stress. The "Facts" area is quite good as well, as it contains a number of fact sheets and how PTSD is most effectively treated.
