1 in 5 Iraq and Afghanistan vets have PTSD or ‘major depression.’

“Some 300,000 U.S. troops are suffering from major depression or post traumatic stress (PTSD) from serving in the wars in Iraq and Afghanistan, and 320,000 received brain injuries,” according to a study from the RAND Corporation. The study put the percentage of PTSD and depression at 18.5 percent, but only “about half have sought treatment.”
