Brain zaps may unlock lost words after stroke
NCT ID NCT04375722
First seen Jul 13, 2026 · Last updated Jul 14, 2026 · Updated 1 time
Summary
This study explores whether a gentle, non-invasive brain stimulation technique called transcranial alternating current stimulation (tACS) can help improve language recovery in people who have lost speech abilities after a stroke. Researchers will also test the same stimulation in healthy volunteers to understand how it affects normal language function. The goal is to see if tACS can boost performance on verbal short-term memory tasks and produce measurable changes in brain activity.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- transcranial alternating current stimulation (tACS)
- What this could lead to
- If successful, this could point toward a non-invasive way to boost language recovery in people with post-stroke aphasia.
- What could go wrong
- This is an early-stage study with only 50 participants, so results may not apply to everyone. The effects of tACS on language are still uncertain.
