Research shows that symptoms of posttraumatic stress disorder (PTSD) are particularly high in veterans, and that trauma-related nightmares and sleep disturbances are common in veterans with PTSD. This is of concern because people with these problems will often use unhealthy ways of coping. Although trauma-related nightmares and difficulty sleeping are highly distressing, there are helpful treatments that do not involve taking medication. One of these treatments teaches specific skills to help people improve their sleep habits and to change their nightmares so that they are less upsetting. This treatment can be very helpful and research shows that people experience decreases in the frequency and severity of their nightmares, decreased symptoms of depression and PTSD, and improved sleep quality and quantity after completing treatment. However, because this treatment has only been studied with civilians, it is not clear how well this treatment works for veterans.
