Double brain zapping: could two stimulation methods beat depression?
NCT ID NCT05725239
First seen Jul 13, 2026 · Last updated Aug 13, 2026 · Updated 3 times
Summary
This study tests whether combining two types of stimulation—one that targets a nerve in the ear (or a surgically implanted neck device) and another that uses magnetic pulses on the scalp—can better relieve symptoms of treatment-resistant depression. Participants attend six treatment sessions, receiving each type alone or both together, to see which combination works best. The goal is to find a more effective option for people whose depression hasn't improved with standard treatments.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Vagus nerve stimulation (VNS) and transcranial magnetic stimulation (TMS)
- What this could lead to
- If it works, this combined approach could offer a new treatment option for people with depression that hasn't responded to standard therapies.
- What could go wrong
- This is a small, early-phase study with only 24 participants, so results may not apply broadly. The treatment may cause side effects or not improve symptoms significantly.
