The current study aims to examine information processing during sleep in non-insomniac individuals with high vulnerability (HV) to stress-related sleep disturbances.\r\n\r\n\r\nMethods\r\n\r\n\r\nTwenty-seven non-insomniac individuals were recruited, 14 with low vulnerability and 13 with HV. After passing a screening interview and polysomnographic recording, subjects came to the sleep laboratory for 2 nights (a baseline night and a stress-inducing night) for event-related potentials recordings.\r\n\r\n\r\nResults\r\n\r\n\r\nThe HV group demonstrated shorter P2 latency during the first 5 min of stage 2 sleep and higher P900 amplitudes under the stress condition during slow-wave sleep, which indicates an increased level of inhibitory processes. In addition, they had shorter N1 latencies during slow-wave sleep that could indicate an elevated level of attention processing during deep sleep.\r\n\r\n\r\nConclusions\r\n\r\n\r\nUnlike patients with chronic insomnia, individuals with high sleep vulnerability to stress show a compensatory process that may prevent external stimulation from interfering with their sleep. This may be one of the factors preventing their acute sleep disturbances from becoming chronic problems. | 關聯: | Psychiatry and Clinical Neurosciences,69(2),84-92 10.1111/pcn.12206 |
