Can a gentle Head-Zap ease ADHD symptoms in kids?
NCT ID NCT06974136
First seen Aug 04, 2026 · Last updated Aug 05, 2026 · Updated 1 time
Summary
This trial tests whether a non-invasive technique called transcranial electrical stimulation (tES) can help reduce ADHD symptoms and improve thinking skills in children and teenagers aged 7 to 18. The approach uses low-intensity electrical currents applied to the scalp to gently modulate brain activity. Researchers will compare two forms of stimulation—tDCS and tACS—and measure changes in ADHD symptoms, executive function, and brain activity using EEG.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- transcranial electrical stimulation (tES), including transcranial direct current stimulation (tDCS) and transcranial alternating current stimulation (tACS)
- What this could lead to
- If effective, this could offer a non-drug, low-side-effect option to help children with ADHD manage symptoms and improve focus and thinking.
- What could go wrong
- This is a small, early-stage trial, so results may not apply broadly. The stimulation is generally safe but may cause mild tingling or itching, and its long-term benefits are not yet proven.
