Scientists probe brain circuits to unlock Dystonia's secrets
NCT ID NCT06716983
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study aims to understand how deep brain stimulation (DBS) changes brain activity in people with dystonia, a movement disorder. Researchers will use brain scans and electrical recordings from 15 participants who already have DBS implants. The goal is to learn more about the disease and potentially improve future treatments, not to test a new therapy.

Who is studied
The investigators will enroll 15 consecutive patients with idiopathic or genetic dystonia who have already undergone DBS surgery of the globus pallidus internus with a neurostimulator capable of chronically recording LFPs and which is fully compatible with magnetic fields up to 3 Tesla.
