Methods Sleep behavior and all night polysomnographic recording were performed in 32 heroin addict and 21 normal controls. Results ①Compared with control group, the incidences of sleep continuity disturbance, easy wake, hypersomnia and difficulty falling asleep in patient group weer significantly increased (P < 0.05 — 0.01 ). ②REM latency was shorter in patients than that in controls; and slow wave sleep, steeper, sleep maintenance in patient group were markedly decreased (P < 0.05 — 0.01 ). While the awake dutation, arousal times, sleep stage, tate of awake/asleep were increased in patient group ( P <0.05—0.01);The average duration in Ⅲ and Ⅳ stage was [(9.1 ± 1.3)%] and the duration in Ⅰ stage was [ (14.8 ± 2.8)% ]. Conclusions It is consistent the behavioral dimmers of sleep with the physiologic dysfunction in heroin addicts, and the pathogenesis of sleep disturbance may result from the etiology of heroin addicts.
