Can your Brain's expectations fool you? Parkinson's hallucination study seeks answers
NCT ID NCT07427498
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This observational study will examine whether prior expectations increase false perceptions in Parkinson's patients who experience visual hallucinations. About 60 participants, including patients with and without hallucinations and healthy volunteers, will complete a computer-based face detection task and cognitive tests. The goal is to better understand the mechanisms behind hallucinations in Parkinson's disease.
