Sleep Variability in Military-related PTSD: A Comparison to Primary Insomnia and Health Controls

There were 45 Operation Enduring Freedom, Iraqi Freedom, and Operation New Dawn (OEF/OIF/OND) Veterans seeking treatment for posttraumatic stress disorder (PTSD) and sleep problems that were compared to 25 patients with primary insomnia and 27 healthy controls to examine differences in sleep patterns. Sleep symptoms in Veterans with PTSD were more variable across nights and less consistent across patients relative to sleep symptoms in insomnia patients without PTSD.
