Neuroplasticity in REM Sleep Behavior Disorder

REM sleep behavior disorder (RBD) is a condition in which people physically act out their dreams while sleeping. Some people with RBD may later develop neurological conditions such as Parkinson's disease or related disorders. This study will examine changes in the brain over a two-year period using advanced brain imaging (7T MRI) and other neurological tests. Researchers will compare people with RBD to people without the disorder to better understand how the brain changes over time and identify potential early signs of neurological disease.
