| Popis: | Sleep parameters in individuals with chronic PTSD were investigated. PTSD subjects were not found to differ from age-matched controls in total number of arousals, but there was a differential distribution of arousals across the sleep period. Control subjects showed a normal arousal pattern, with decreased arousals during the first half of the sleep period reflecting the delta sleep prominent during this period, whereas PTSD subjects demonstrated an abnormal arousal pattern characterized by a relatively consistent frequency of arousals across the sleep period. Overall, PTSD subjects had a decreased percentage of slow-wave sleep relative to controls, which may explain their increased arousals during the first half of the night. In addition, electrodermal recordings indicated that PTSD subjects showed significantly less storming than controls throughout the recording period. |
