First seen Nov 01, 2025 · Last updated May 15, 2026 · Updated 22 times

Summary

This study looks at whether using a CPAP machine (commonly used for sleep apnea) can lower high blood pressure when lying down at night and help with dizziness upon standing in people with autonomic failure. About 59 adults aged 40-80 with conditions like Parkinson's disease or multiple system atrophy will spend 3-5 days in a research center. They will receive both active and sham CPAP during daytime and overnight sessions to measure blood pressure changes.
