目的观察单相抑郁障碍患者和双相抑郁障碍患者的睡眠特征以及其认知功能的差异。方法选取2015 02—2016 10茂名市第三人民医院院就诊的单相抑郁障碍患者73例(单相组)、双相抑郁障碍患者76例(双相组),以及同期的健康志愿者60例(对照组)...目的观察单相抑郁障碍患者和双相抑郁障碍患者的睡眠特征以及其认知功能的差异。方法选取2015 02—2016 10茂名市第三人民医院院就诊的单相抑郁障碍患者73例(单相组)、双相抑郁障碍患者76例(双相组),以及同期的健康志愿者60例(对照组)。采用多导睡眠监测系统对受试者的睡眠特征进行监测比较,采用改良过的韦氏成人智力量表(Wechsler Adult Intelligence Scale,WAIS)评定受试者的语言智商、操作智商和总智商;采用韦克斯勒成人记忆量表(Wechsler memory scale,WMS)评定受试者的记忆能力;采用功能失调性态度问卷(Dysfunctional attitudes scales,DAS)评估认知结构。结果 3组受试者的多导睡眠监测指标中,除第2期睡眠时间/比例和快速动眼期睡眠时间/比例外,其他指标差异均有统计学意义( P <0.05)。单相组与双相组患者在总睡眠时间、觉醒时间、觉醒次数、睡眠潜伏期、第1期时间/比例和第3期时间/比例中,差异均有统计学意义( P <0.05)。3组患者WAIS和WMS评分比较,差异有统计学意义( P <0.05)。单相组和双相组在总智商和记忆商数比较中,差异有统计学意义( P <0.05),但2组的语言智商和操作智商比较,差异无统计学意义( P >0.05)。3组受试者DAS评分差异存在统计学意义,双相组显著高于单相组( P <0.05)。其中强制性、依赖性、认知哲学方面,双相组的评分显著高于单相组( P <0.05);但2组患者的脆弱性、吸引和排斥、完美性、寻求赞许及自主性态度方面比较,差异无统计学意义( P >0.05)。结论 单相抑郁障碍和双相抑郁障碍患者均存在睡眠进程和睡眠结构紊乱的问题,认知能力也受到一定程度的损伤,其中双相抑郁患者更为严重。展开更多
