Brain zaps reveal how BDD patients see faces differently
NCT ID NCT05607121
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This completed study looked at how a noninvasive brain stimulation technique called TMS affects the way people with body dysmorphic disorder (BDD) process visual information. Forty adults with BDD or mild symptoms received either intermittent or continuous TMS over the parietal brain region, then had their brain activity scanned while viewing faces. The goal was to understand changes in brain connections and visual perception, not to treat the disorder.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- transcranial magnetic stimulation (TMS)
- What this could lead to
- If successful, this study could reveal how brain stimulation changes visual perception in body dysmorphic disorder, pointing toward new ways to understand or treat the condition.
- What could go wrong
- This is a small, early-stage observational study with only 40 participants. It is not designed to test a treatment, so any insights are preliminary and may not lead to direct therapies.
