抑郁症患者快动眼睡眠特征及其与抑郁水平的相关性

目的 探讨抑郁症患者多导睡眠图特征及快动眼睡眠(REM)变异度与抑郁严重程度是否存在相关性.方法 应用多导睡眠图对纳入的符合CCMD-3单项抑郁症诊断标准的患者90例进行整夜多导睡眠监测与蒙哥马利抑郁量表(MADRS)评定,并采用30例正常被试作为对照.结果 与正常对照组相比,抑郁症患者在睡眠进程方面的表现为睡眠潜伏期延长(25.5±15.25)min],睡眠效率下降(0.83±0.11)];睡眠结构方面,抑郁症患者1期睡眠百分比增加(27.7±16.38)%)],REM睡眠百分比增加(22.8±6.1)%],2期睡眠百分比降低(40.2±11.3)%)],慢波睡眠百分比降低(11.8±9.32)%)];快动眼睡眠改变明显,REM睡眠潜伏期明显缩短(79.27 ± 30.44)min],REM活动度增加(129.00±53.12)u],REM强度增加(36.7 ± 14.0)u/min],以及REM密度增加(159.2±57.2)u/min];REM睡眠参数与MADRS评分进行相关性分析未发现之间存在相关性.结论 抑郁症患者睡眠进程、睡眠结构及REM睡眠存在系列改变,REM睡眠的改变可能是特异性的,可以用来诊断抑郁症,但REM睡眠的变异度与抑郁严重程度可能不存在相关关系.

Abstract：

Objective To explore the characteristics of polysomnography (PSG) of depressed patients and the correlation between rapid eye movement (REM) and severity degree of depression. Methods Polysomnography was used to assess patients'sleep condition and Montgomery-Asberg depression scale (MADRS) was used to assess the severity degree of depression. 90 patients and 30 healthy controls were included. Results Compared to healthy controls,sleep progress of depressed patients changed as follow:prolonged sleep latency((25.2 ±15.25) minutes) ,lowered sleep efficiency(0.853 ±0.11) ;the architecture of sleep also changed:percentage of stage 1 increased( (27.7 ± 16.38) % ),percentage of REM sleep increased( (22. 8 ± 6. 1 ) % ) , percentage of stage 2 decreased ((40.2±11.3)%), percentage of slow wave sleep decreased ((11.8 ±9. 32)%); REM sleep significantly changed; decreased REM latency((79. 27 ±30. 44) minutes) , increased REM activity((129. 0 ±53. 12) u) .increased intensity of REM((36.7 ±14.0)u/min), increased REM density((159.2 ±57.2)u/min) were observed in depressed patients. There was no obvious correlation between the variance of REM and severity degree of depression. Conclusion There are a series of changes in sleep progress, architecture and REM sleep of depression and the change of REM sleep can be specified to diagnose depression. However,there is no causality between REM variance and severity of depression.
