The Department of Veteran Affairs has made available something called the Iraq War Clinicians Guide, 2nd Edition, intended to help healthcare practitioners recognize and diagnose Post-Traumatic Stress Disorder ("PTSD") in their patients. Although the material is intended for mental health care providers, in reality, it's probably useful information for most clinicians to have handy. A link to the guide's contents is here.
(The Iraq War Clinicians Guide was developed by members of the National Center for PTSD and the Department of Defense, and it was developed specifically for clinicians and addresses the unique needs of veterans of the Iraq war.)
If you have the latest version of Adobe Acrobat Reader, you can download the entire guide, or you can download specific chapters of interest. Kudos to the VA for making this information available on the Web.
