Psychobiology of sleep disturbances in posttraumatic stress disorder.
Sleep disturbances are prominent complaints of PTSD patients. Some, but not all, of the polysomnographic studies support the occurrence of sleep disruption. The main dimensions of sleep disturbance in the disorder relate to arousal regulation and REM-related functions of dreaming and memory processing. Both of these issues are relevant to the pathogenesis of PTSD and manifestations of the disorder during wake states. Studies elucidating the effects of treatment on sleep parameters are an important direction for future research.
