Can a smart algorithm keep depression from returning?
NCT ID NCT07779330
First seen Aug 21, 2026 · Last updated Sep 03, 2026 · Updated 2 times
Summary
This trial tests a personalized approach to maintaining improvement in people with treatment-resistant depression. Participants who previously responded to a type of brain stimulation called iTBS will receive maintenance stimulation scheduled by a symptom-based algorithm, along with wearable sensors to detect early signs of relapse. The goal is to see if this combination can keep depression at bay and reduce the chance of it coming back.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Individualized brain stimulation (iTBS) guided by brain scans, plus a symptom-based algorithm to schedule retreatment
- What this could lead to
- If successful, this approach could help people with hard-to-treat depression stay well longer and catch relapses early, reducing the need for frequent hospital visits.
- What could go wrong
- This is a small, early-stage study without a comparison group, so results may not apply broadly. Brain stimulation can cause side effects like headache or discomfort, and the algorithm may not work for everyone.
