Abstract

This study was designed to survey the prevalence and distribution of non-motor symptoms (NMS) in Parkinson's disease (PD) patients in Shanghai, China, and to investigate the association between NMS and health-related quality of life (HRQoL). One hundred fifty-five PD patients were evaluated using the NMS Questionnaire 30 (NMSQuest), Unified Parkinson's Disease Rating Scale (UPDRS) and Parkinson's Disease Questionnaire-39 (PDQ-39). These data were compared with an international cross-sectional study, and the associations of motor and non-motor measures with HRQoL were estimated. Predictors of HRQoL were sought through multiple linear regression analyses. Each PD patient had eight different individual NMS on average. The problems of memory (65.82%), constipation (64.56%) and nocturia (61.39%) were the most frequent complaints. NMS prevalence in PD patients in Shanghai was consistent with that in the international study, although the composition proportions were different. There was a significant association of PDQ-39 score with NMSQuest score (rs=0.433, p=0.000), UPDRS III score (rs=0.473, p=0.000), Hoehn and Yahr (H-Y) stage (rs=0.567, p=0.000), disease duration (rs=0.220, p=0.005), and levodopa equivalent dosage (rs=0.263, p=0.001). H-Y stage (disease severity) and NMS score were the strongest predictors for PDQ-39 score. This study confirmed that NMS are common in PD, occurring across all disease stages and have a great impact on quality of life. NMS progression contributes significantly to HRQoL decline, and should be well recognized and treated.
