Sound waves to soothe PTSD? new trial tests ultrasound on the brain
NCT ID NCT06820138
First seen Jun 27, 2026 · Last updated Sep 16, 2026 · Updated 4 times
Summary
This phase 2 trial tests whether low intensity focused ultrasound, aimed at a deep brain region called the amygdala, can ease PTSD symptoms in 60 veterans. The treatment is non-invasive and uses sound waves similar to diagnostic ultrasound. Researchers will measure symptom changes and daily functioning over one month.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- low intensity focused ultrasound (Brainsonix Pulsar device)
- What this could lead to
- If it works, this could offer a new, non-invasive way to reduce PTSD symptoms and improve daily functioning for veterans.
- What could go wrong
- This is an early phase 2 trial with only 60 people, so results may not apply to everyone. The effects may be small or short-lived, and some participants may receive a sham treatment.
