Is the title of a new RAND report that estimates nearly one in five military service members who have returned from Iraq and Afghanistan report symptoms of post traumatic stress disorder or major depression, yet only slightly more than half have sought treatment. Researchers also found about 19 percent of returning service members report experiencing a possible traumatic brain injury while deployed, with 7 percent reporting both a probable brain injury and current PTSD or major depression. In what RAND describes as a “major health crisis”, researchers estimate that PTSD and depression among returning service members will cost the nation up to $6.2 billion in the two years following deployment, including both direct medical care and costs for lost productivity and suicide. Injured veterans returning from war present unique challenges for insurers as I.I.I. president Dr. Robert Hartwig outlined in a January 2006 report: When Johnny Comes Marching Home.
