Brain zapping showdown: which target tames tremors best?
NCT ID NCT07526155
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested two different spots in the brain for deep brain stimulation (DBS) to control essential tremor. Eleven people who did not get relief from medication had electrodes placed in both the usual target (VIM) and a newer one (PSA). The goal was to see if the newer spot works just as well while using less energy and causing fewer side effects.
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 (DBS) device
- What this could lead to
- If PSA stimulation proves non-inferior, it could offer a more energy-efficient and safer option for controlling essential tremor with DBS.
- What could go wrong
- This is a very small trial (11 people) comparing two established targets, so results may not apply widely. The study is completed but not yet published, so real-world benefits remain uncertain.
