Sleep in Parkinson’s Disease: A Comparison Between Those With and Without Deep Brain Stimulation

Sleep disturbance is highly prevalent in Parkinson’s disease (PD) and can be caused by a number of factors.  Ninety-three percent of the participants of this study endorsed at least some symptoms of sleep disturbance.  Of those reporting sleep disturbance, 52% were in the mild-to-moderate to severe range. The study found that individuals who have DBS reported less night-time sleep disturbance due to motor symptoms and other PD symptoms.   Additionally, the participants who had DBS reported longer duration of consecutive hours of night-time sleep as compared to the individuals who did not have DBS. This report gives an understanding about contributing factors to sleep disturbance for individuals with PD, and practical recommendations that may help improve sleep.
