Actigraphic sleep monitoring in posttraumatic stress disorder (PTSD) patients

Posttraumatic stress disorder (PTSD) patients frequently complain that they suffer from sleep disturbances. To date, the polysomnographic studies that have attempted to study PTSD patients' subjective complaints of sleep difficulties have produced conflicting results. The objective of the present study was to compare PTSD patients' subjective complaints of poor sleep and objective actigraphic recordings of their sleep over a period of several consecutive nights. The results indicate that PTSD patients do not suffer from poorer sleep than a control group, based on actigraphic measures, and that their subjective sleep evaluation is inconsistent with objective sleep measures. These patients fail to correctly estimate their sleep. (C) 1997 Elsevier Science Inc.
