Can a common drug reveal Parkinson's before symptoms start?
NCT ID NCT04386317
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether terazosin, a drug used for high blood pressure, can change heart nerve activity in people at high risk for Parkinson's disease. Researchers are studying 15 adults with REM sleep behavior disorder (a strong early sign of Parkinson's) to see if the drug affects heart scans and relates to symptom changes. The goal is to learn more about the earliest stages of Parkinson's, not to treat or cure it.
