Brain zaps may curb self-harm in teens
NCT ID NCT07152925
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study tests whether a gentle, non-invasive brain stimulation technique called tACS can help teenagers who hurt themselves without wanting to die. Sixty teens aged 12-18 will receive either real or fake stimulation for 7 days. Researchers will measure changes in self-harm behavior, impulsivity, and depression.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- transcranial alternating current stimulation (tACS)
- What this could lead to
- If it works, this could point toward a safe, non-drug way to help teens with self-harm urges.
- What could go wrong
- This is a small, early-stage trial with no phase, so results may not be conclusive. The effect may be small or no better than sham stimulation.
