Zap to talk: brain stimulation tried for aphasia after stroke
NCT ID NCT02101398
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study tested whether a gentle electrical current applied to the scalp (tDCS) during speech therapy could help stroke survivors with aphasia name objects better. Only 5 people took part, and the study was stopped early, so the results are not reliable enough to draw conclusions.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- transcranial direct current stimulation (tDCS) device
- What this could lead to
- If it had succeeded, this could point toward a way to boost speech therapy for people with aphasia after a stroke.
- What could go wrong
- The study was very small (only 5 participants) and was terminated early, so we cannot draw reliable conclusions. It also only included French-speaking, right-handed patients, so results may not apply to others.
