Can a surprise twist help erase trauma? new PTSD trial investigates

NCT ID NCT05853627

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tests whether adding an unexpected element (like singing) during memory reactivation, combined with the drug propranolol, can reduce physical stress responses to traumatic memories in people with PTSD. Eighty adults with trauma history will be randomly assigned to standard or mismatch reactivation sessions over six weeks. The goal is to see if the mismatch approach better weakens the memory and lowers heart rate and sweat responses during trauma recall.

What this could mean

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

Active substance

Propranolol

What this could lead to

If successful, this could lead to a more effective treatment for PTSD by weakening traumatic memories and reducing physical stress reactions.

What could go wrong

This is a small, early-phase study (80 participants) testing a novel approach. The mismatch technique may not improve outcomes over standard reactivation, and propranolol can cause side effects like low blood pressure or fatigue.
