Neuroplasticity in REM Sleep Behavior Disorder


REM sleep behavior disorder may predict the eventual symptom development of Parkinson’s disease, dementia with Lewy bodies, or multiple system atrophy. This occurs over years to decades and the sleep disorder may hide other typical symptoms and result in a delay in diagnosis. We are studying the changes in the brain over two years. We will do high field MRI’s (7T) and other tests of neurological function of people who have REM sleep disorder and people who don’t have this disorder (matched for age and sex).
