Could pain be an early warning sign for Parkinson's?
NCT ID NCT07365566
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at pain in people with idiopathic REM sleep behavior disorder (iRBD), a condition that strongly increases the risk of developing Parkinson's disease. Researchers will compare pain levels and patterns between 24 participants with iRBD and a control group with narcolepsy and RBD. The goal is to see if pain could be an early clue for Parkinson's, helping with earlier diagnosis and treatment.
