Consortium to Alleviate PTSD researchers report in JAMA Network Open that treatment for combat-related PTSD, which affects hundreds of thousands of U.S. military personnel and veterans, can be both fast and effective for a majority of patients. Their study showed clinically significant reductions in PTSD symptoms in over 60 percent of patients and long-term remission of diagnosis in more than 50 percent after three weeks of outpatient Prolonged Exposure (PE) therapy. Study participants similarly showed significant improvements in related disability and daily functioning.
