Summary

This study looks at sleep problems in people with Parkinson's disease and those with a sleep disorder called REM sleep behavior disorder (iRBD). Researchers will compare sleep quality among these groups and healthy volunteers using overnight sleep tests. The goal is to better understand how sleep is affected in these conditions.
