"Rates of posttraumatic stress disorder (PTSD) are higher in U.S. military veterans than in the general U.S. population. Reported rates of PTSD in veterans who served in Vietnam, the Gulf War, and Operation Enduring Freedom/Operation Iraqi Freedom range from about 15 percent to 12 percent to 14 percent, respectively. By comparison, the lifetime prevalence of PTSD among adult Americans is estimated to be about 7 percent.
According to Thomas Mellman, M.D., a professor of psychiatry and director of the Center for Clinical and Translational Research and Stress/Sleep Studies at Howard University College of Medicine, sleep disturbances are among the most persistent symptoms of PTSD. New research findings can help to expand understanding of disturbed sleep's contribution to the onset and maintenance of psychiatric distress in veterans, said Mellman, who chaired a session on PTSD, other psychiatric disorders, and sleep at the joint annual meeting of the American Academy of Sleep Medicine and Sleep Research Society in Boston in June."
