Поведенческие реакции больных инсомнией и полисомнографическая структура сна
The aim of the study was to reveal relationship between behavioral reaction in patients with chronic insomnia and polysomnographic sleep structure. There was hypothesized that sleep hygiene disturbances and passivity (self-restricting behavior) are related to worsen objective sleep. 62 patients with psychophysiological insomnia participated in neurological, psychological observations and polysomnography during the night. Sleep hygiene disturbances were found in 61,3% of patients, self-restricting behavior - 43,5%. Only two patients used active coping strategies during the day. Sleep hygiene disturbances were not related to the illness duration and subjective sleep appraisals but were related to the difficulties of sleep maintenance (more awakes). Self-restrictive behavior was related to longer illness duration and decrease in the portion of delta-sleep in the sleep structure.
