Brain stimulation for Parkinson's linked to weight gain – study investigates why
NCT ID NCT00221793
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at why people with Parkinson's disease often gain weight after deep brain stimulation of the subthalamic nucleus. Researchers measured energy use and metabolism in 20 patients before and after treatment. The goal was to understand if weight gain is due to changes in energy balance.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- deep brain stimulation
- What this could lead to
- If successful, this could help doctors understand and manage weight changes in Parkinson's patients after brain stimulation.
- What could go wrong
- This is a small, completed observational study with only 20 participants, so findings may not apply to all patients. It does not test a new treatment.
