Abstrakt: Question of the Study The self-reported prevalence of daytime fatigue and sleep disorders in patients with Parkinson's disease (PD) was to be estimated, and their correlation to each other was to be examined. Furthermore, the patients' attributions concerning their symptoms and the symptoms' correlation with the amount of daytime sleep are presented. Patients and Methods A questionnaire assessing sleep disorders, sleep behaviour, daytime fatigue, etc., was sent to 12 000 PD patients. With a return rate of 63%, data from 6620 patients could be analysed. Results The prevalence of daytime fatigue (35% vs. 71%) and sleep disorders (23% vs. 76%) was significantly increased when compared to before the onset of PD (P < 0.001). In addition, both symptoms (P < 0.001) as well as their changes (P < 0.001) were highly correlated with each other. Consistently, patients named disturbed night-time sleep as the most frequent cause of daytime fatigue (19%), which was mainly attributed to nocturia (20%). Fifty-three per cent of the patients who were currently not suffering from sleep disorders still complained of daytime fatigue, compared to 27% before the disease. Conclusions The disturbed night-time sleep in PD is associated with increased subjective daytime fatigue. However, additional factors such as medication, duration, and severity of disease are responsible for the occurrence of daytime fatigue. [ABSTRACT FROM AUTHOR]
