Prevalence and profile of nocturnal disturbances in Chinese patients with advanced-stage Parkinson’s disease: a cross-sectional epidemiology study

BACKGROUND: The impact of nocturnal disturbance (ND) in Parkinson’s disease on quality of life of patients in Western Countries is increasingly understood. Our study aimed to investigate ND prevalence and its quality of life impact in patients with advanced Parkinson’s disease in China. METHODS: In...

Sumario:BACKGROUND: The impact of nocturnal disturbance (ND) in Parkinson’s disease on quality of life of patients in Western Countries is increasingly understood. Our study aimed to investigate ND prevalence and its quality of life impact in patients with advanced Parkinson’s disease in China. METHODS: In a multicenter, tertiary-care hospital, outpatient-based, cross-sectional study, patients with advanced Parkinson’s disease (Modified Hoehn & Yahr [H&Y] Stage II–IV with ≥3 h awake “off” time/day) from 10 tertiary hospitals throughout China completed the Parkinson’s Disease Sleep Scale-2 (PDSS-2) and Parkinson’s Disease Questionnaire-39 (PDQ-39). The primary endpoint was the percentage of patients with significant ND (PDSS-2 total score ≥ 15). Additional endpoints were demographic and clinical characteristics, PDSS-2 and PDQ-39 total and subscale scores, correlation between PDSS-2 and PDQ-39, and risk factors for ND and higher PDSS-2 or PDQ-39 scores. RESULTS: Of 448 patients analyzed (mean age 63.5 years, 47.3% female), 70.92% (95% confidence interval: 66.71, 75.13) had significant ND. Presence of ND and higher PDSS-2 scores were associated with longer disease duration and higher H&Y stage. Presence of ND was also associated with more awake “off” time/day and female sex. PDQ-39 scores were significantly worse for patients with ND versus those without ND; worse scores were associated with more awake “off” time/day, female sex, and higher H&Y stage. PDSS-2 and PDQ-39 total scores were associated: Pearson correlation coefficient 0.62 (p < 0.001). CONCLUSIONS: In China, ND was highly prevalent in patients with advanced Parkinson’s disease and adversely impacted quality of life. This study highlights the importance of early diagnosis and optimized management of ND in patients with Parkinson’s disease in China.
