What this research studies

You would have research-quality overnight polysomnograms (sleep studies) recorded, with over 300 people with REM sleep behavior disorder (RBD) and matched control participants enrolled. The same participants will have recordings twice, two years apart, while a central PSG Core standardizes scoring and analysis across sites. Your de-identified sleep signals, including REM sleep without atonia (RSWA), would be pooled and shared with researchers to define biomarker ranges and how they change over time. Participation typically involves overnight visits at a participating sleep center and allowing your sleep data to be used for future research.

Who could benefit from this research

Good fit: Ideal candidates are people diagnosed with or showing symptoms of REM sleep behavior disorder who can undergo overnight polysomnography and attend follow-up visits, along with matched healthy control participants.

Not a fit: People without RBD symptoms or those unable or unwilling to complete overnight sleep studies or follow-up visits are unlikely to receive direct benefit from this project.

Why it matters

Potential benefit: If successful, this work could help identify early sleep-based signs of Parkinson’s and related synucleinopathies, enabling earlier monitoring and future neuroprotective trials.

How similar studies have performed: Retrospective and single-site studies have shown that REM sleep without atonia (RSWA) often increases over time and can predict conversion to synucleinopathies, but large prospective multicenter validation is still relatively new.
