NCT ID NCT06270290
First seen Jun 06, 2026 · Last updated Jun 23, 2026 · Updated 2 times
Summary
This study is investigating whether people with REM sleep behavior disorder (RBD) have a higher history of concussions or contact sports compared to those without RBD. Researchers will interview 140 participants (70 with RBD and 70 without) about their past head injuries and sports activities. The goal is to see if these factors are more common in RBD, which could help understand the disorder's causes.
