The U.S. Army and the U.S. Marine Corps continue seeking ways to deal with PTSD (Post Traumatic Stress Disorder). One of the latest efforts is a marine program that uses a civilian program called Mind Fitness. This is a series of mental exercises developed to reverse the ill effects of stress. When the marines came across Mind Fitness, the program had already treated 35,000 people, with an 85 percent success rate. Initial tests with marines showed a similar rate of effectiveness. Now the marines are rolling out the program (20 hours of training spread over two months) on a wider scale, and the other services are looking into it.
