Could a brain ZAP boost OCD therapy? small study hopes to find out
NCT ID NCT06840951
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This small pilot study tests whether giving a brief, non-invasive brain stimulation (rTMS) before cognitive behavioral therapy (CBT) can help people with obsessive-compulsive disorder (OCD) get better results. Ten adults with OCD will receive rTMS to improve thinking skills like flexibility, then complete CBT. The goal is to see if this combination reduces OCD symptoms more than CBT alone.
