Parkinson's study probes links between perception, mood, and sleep
NCT ID NCT05483036
First seen Jun 25, 2026 · Last updated Jun 26, 2026 · Updated 1 time
Summary
This completed observational study looked at how people with Parkinson's disease perceive the world, including unusual experiences like visual hallucinations. Researchers surveyed 54 participants online to see how these perceptual experiences relate to cognition, mood, and sleepiness. The goal was to better understand these connections, not to test any treatment.
