Can zapping two brain areas beat OCD?

NCT ID NCT04958096

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study is testing whether adding stimulation to the front part of the brain can improve standard deep brain stimulation (DBS) for severe obsessive-compulsive disorder (OCD). Fifteen adults with OCD that hasn't improved with other treatments will get DBS plus an extra set of electrodes in the prefrontal or cingulate cortex. Researchers will track brain signals and OCD symptoms for up to two years to see if the extra stimulation helps.

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 and cortical stimulation
What this could lead to
If successful, this could point toward a more effective brain stimulation treatment for severe OCD that doesn't respond to other therapies.
What could go wrong
This is a very early, small study with only 15 people. It's testing a new combination of brain stimulation, so it may not work better than standard DBS, and there are surgical risks from implanting extra electrodes.
