NCT ID NCT06127056

First seen Jul 22, 2026 · Last updated Jul 23, 2026 · Updated 1 time

Summary

This trial tests whether a non-invasive brain stimulation technique called HD-tACS can reduce urges and behaviors linked to non-suicidal self-injury in adolescents aged 12 to 18. Participants receive either real or sham stimulation over several sessions, and researchers track changes in self-harm frequency, impulsivity, and mood using questionnaires and brain scans. The goal is to see if this approach offers a safe, drug-free way to help teens who struggle with self-harm.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
high-definition transcranial alternating current stimulation (HD-tACS) delivered via scalp electrodes
What this could lead to
If it works, this could point toward a non-drug, brain-based treatment for reducing self-harm urges in adolescents.
What could go wrong
This is a small, early-stage trial with only 40 participants, so results may not apply broadly. The sham control means some may not receive active stimulation, and individual responses can vary.
