伴快速眼球运动睡眠行为障碍的帕金森病患者临床特征

目的 评价快速眼球运动睡眠行为障碍(RBD)在帕金森病(PD)患者中的患病率以及伴发RBD的PD患者临床特征.方法 2007年连续入组124例PD患者,采用非运动症状问卷(NMSquest)第25项问答结果调查PD患者中RBD患病率;将入选患者分为RBD组(78例)和非RBD组(13例),采用统一PD评分量表(UPDRS)、Hoehn-Yahr(H-Y)分级比较2组运动症状严重程度和运动并发症发生情况;选用NMSquest量表比较2组非运动症状发生情况,选用MMSE、汉密尔顿抑郁量表(HAMD)、汉密尔顿焦虑量表(HAMA)、帕金森病睡眠量表(PDSS)和Epworth嗜睡量表(ESS)比较2组认知功能、焦虑和抑郁、夜间睡眠障碍和日间思睡程度.结果 (1)RBD的患病率为62.9%(78/124);(2)RBD组患者的病程(3.8±2.8)年]显著短于非RBD组(5.0±2.5)年,t=-1.972,P=0.048],但在性别、年龄、起病年龄、发病类型、左旋多巴等效剂量(LDE)和用药种类上2组差异没有统计学意义;(3)在运动症状中RBD与非RBD组在H-Y分级、UPDRS-Ⅱ、Ⅲ、Ⅳ评分以及运动并发症发生率方面差异无统计学意义;(4)在非运动症状中胃肠道功能、自主神经系统功能、精神和睡眠活动等方面的不良症状在RBD组的发生率显著高于非RBD组,但是认知、焦虑和抑郁、夜间睡眠障碍和日间思睡的严重程度在2组间差异没有统计学意义.结论 RBD在PD患者中的患病率较高,伴发RBD的PD患者病程较短且非运动系统受累更加广泛.

A pilot study on the clinical characteristics of Parkinson' s disease patients with rapid eye movement sleep behavior disorder

Objective To study the incidence of rapid eye movement sleep behavior disorder (RBD) and its impact on the clinical manifestations of patients with Parkinson' s disease (PD). Methods One hundred and twenty-four PD patients were included into this study and each of them was given the non motor symptoms questionnaire (NMSquest) to investigate the incidence of RBD. The PD patients were then divided into the RBD group and non RBD group, according to their answers to the NMSquest. Then the clinical differences were investigated between PD patients with and without RBD on the aspects of demographic characters, Hoehn-Yahr (H-Y) stage, the scores of Unified Parkinson Disease Rating Scale (UPDRS) sub-items, the incidence of non motor symptoms, and the dysfunctions of non motor systems (cognitive impairment, anxiety, depression and sleep disorders ). The evaluation tools of non motor functions include Mini Mental State Exam ( MMSE), Hamilton Depression Scale (HAMD), Parkins' s Disease Sleep Scale (PDSS) and Epworth Sleepiness Scale (ESS). Results ( 1 ) 62.9% (78/124) of the PD patients have been experiencing RBD. (2) The course of the disease in RBD group ( 3.8 ± 2.8 ) was significantly shorter than non RBD group (5.0 ± 2.5, t = - 1. 972, P = 0. 048 ) while the sex, age, onset age and the mode of onset, Levodopa dose equivalents (LDE) and the kinds of medicines showed no difference between the two groups. (3) H-Y stage, the scores of UPDRS sub-items and the incidence of motor complications showed no difference between RBD and non RBD group. (4) Most of the non motor symptoms, including the gastrointestinal dysfunctions, autonomic dysfunctions, mood disorders and sleep disturbances, occurred much frequently in RBD group, however, the scores of MMSE, HAMD, HAMA,PDSS and ESS showed no difference between the RBD and non RBD group. Conclusion RBD commonly occurred in PD patients, and PD patients with RBD have a tendency to suffer from dysfunction of non motor systems.
