Zapping the brain to boost recovery after head injury
NCT ID NCT05327829
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a safe, non-invasive technique called transcranial alternating current stimulation (TACS) to see if it can improve cognitive flexibility and decision-making in people who have had a mild to moderate traumatic brain injury (TBI). Researchers will enroll 30 adults (including healthy volunteers) to check if the approach is feasible and well-tolerated. The goal is to help the brain recover thinking skills after injury.
