The prevalence of sleep disorders in patients with Parkinson's disease. A self-reported, community-based survey.Sleep Med 2002; 3(2):147-9SM
Sleep disruption is common in patients with Parkinson's disease (PD). The goal of our survey was to gain insight into the causes of sleep disruption and into the prevalence of specific sleep disorders in PD.
A sleep questionnaire was mailed to 400 unselected PD patients. Analysis of the results was descriptive.
RESULTS AND CONCLUSION
The results of earlier performed surveys for sleep disruptive factors in PD were confirmed and a high prevalence of a possible rapid eye movement-sleep behavior disorder and restless legs syndrome in PD was found.
