Dr. Alejandro Iranzo, a neurologist at the Hospital Clínic of Barcelona, says that REM sleep behavior disorder can give the first signs of Parkinson's.

“Sleep is important for living, but it is little known: we do not know very precisely how it works and if it does not work, what importance it may have for the patient's quality of life,” he points out. The director of the UB-Adsalutem Sleep Chair assures that good or bad rest gives clues about health.
