Sleep disorders in Parkinson disease

Abstract

Sleep is affected in a large number of patients with Parkinson disease. The mechanisms by which this occurs and the different types of sleep disorders that a patient with Parkinson disease may suffer (insufficient or fragmented sleep, persistent excessive daytime sleepiness, sudden onset of sleep episodes, obstructive sleep apnea (OSA), rapid eye movement sleep behavior disorder, and restless legs syndrome) will be reviewed in this study, as well as their relationship with the dopaminergic system. Finally, the most effective treatments will be proposed.
