Elevated awakening thresholds in sleep stage 3-4 in war-related post-traumatic stress disorder.
Awakening thresholds from sleep stage 3/4 were investigated in 19 DSM-III-defined, war-related post-traumatic stress disorder (PTSD) patients compared with 6 normal controls. Patients had significantly higher awakening thresholds and significantly longer latencies to an arousal response than controls. These results are interpreted to suggest modifications in the depth of sleep as one of the long-term sequelae of traumatic events.
