NCT ID NCT06376331
First seen Jun 25, 2026 · Last updated Jun 26, 2026 · Updated 2 times
Summary
This early study is testing whether a washed fecal transplant (WMT) can improve ADHD symptoms and related issues like sleep problems in children aged 3-17. The idea is that changing the gut bacteria might help the brain via the gut-brain axis. Fifty children will receive the transplant, and doctors will track changes in ADHD severity and sleep quality.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
washed microbiota transplantation (fecal transplant)
What this could lead to
If it works, this could point toward a new way to treat ADHD by targeting the gut-brain connection.
What could go wrong
This is a very early Phase 1 trial with only 50 children, so it is far from proven. The treatment may not work or could cause side effects.
