Brain zapping gets personal: a new approach to treating depression and anxiety
NCT ID NCT07766291
First seen Aug 14, 2026 · Last updated Aug 14, 2026
Summary
This trial is testing whether a personalized form of brain stimulation, called accelerated intermittent theta-burst stimulation (iTBS), can improve symptoms of depression and anxiety in people with treatment-resistant depression. The approach uses brain imaging to target specific neural circuits linked to each person's symptoms. Participants will receive either personalized or standard stimulation, and researchers will measure changes in mood and anxiety levels to see if the personalized approach works better.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Personalized, accelerated intermittent theta-burst stimulation (iTBS) using a transcranial magnetic stimulation (TMS) device
- What this could lead to
- If successful, this could lead to more personalized brain stimulation treatments that effectively reduce both depression and anxiety symptoms in people who haven't responded to standard therapies.
- What could go wrong
- This is a small, early-stage trial (36 participants) focused on measuring brain changes, not a proven treatment. Results may not generalize, and TMS can cause side effects like headache or scalp discomfort.
