Atypical parkinsonism and sleep disturbances

Abstract

In Parkinson disease, sleep disturbances are a common non–motor symptom and are associated with a variety of clinical factors. Sleep–related breathing disorders are a major problem in multiple system atrophy, and sleep architecture is significantly impaired in progressive supranuclear palsy. However, there has been little research conducted into sleep disturbances associated with atypical Parkinsonian syndrome, and many aspects remain unclear. Here, I will review sleep disturbances linked to atypical Parkinsonian syndrome, including their clinical implications.
