Inside the brain: scientists probe reward signals in Parkinson's patients
NCT ID NCT07409207
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 2 times
Summary
This study aims to learn more about the brain activity behind risk-taking and reward-seeking behaviors in people with Parkinson's disease. Researchers will record brain signals during deep brain stimulation surgery while participants play a gambling task. The goal is to understand how certain brain areas communicate and how stimulation affects decision-making. Up to 75 adults scheduled for this surgery will take part.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could help doctors better understand why some people with Parkinson's take risks, potentially guiding future treatments for these behaviors.
- What could go wrong
- This is a small, early-stage observational study focused on measuring brain activity, not testing a treatment. It may not lead to direct clinical changes.

Not a phased trial
Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.
