Abstract:
ObjectiveTo analyze the clinical features of sleep disorder in Parkinson’s disease patients and their association with the quality of life. MethodsThe sleep-related problems, clinical features, and quality of life of 86 Parkinson’s disease patients were analyzed using the Parkinson Disease Sleep Scale (PDSS) and the 39-item Parkinson′s Disease Questionnaire (PDQ39). The relationship between the results of PDSS and PDQ39 was analyzed using the descriptive correlation study. ResultsThe incidence of sleep disorder was 91.86% (79 patients), where fragmented sleep (75.6%) and EDS (74.4%) were the most common problems. The severity of sleep disorder was negatively correlated with the quality of life (P<0.05). ConclusionsThe incidence of fragmented sleep and EDS are the highest in Parkinson’s disease patients with sleep disorder. The severity of sleep disorder is directly correlated with the diminishing of quality of life.
