Summary

This study tests whether a gentle, non-invasive brain stimulation technique called tDCS can help people recover language abilities after a stroke that causes aphasia. Participants receive 14 sessions of tDCS over 7 days combined with speech therapy. Researchers measure language improvements and use brain scans to understand how the stimulation works.

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), a non-invasive brain stimulation technique that applies a weak direct current to the scalp to regulate neuronal activity
What this could lead to
If effective, tDCS could become a safe, low-cost add-on to speech therapy for people recovering language after a stroke.
What could go wrong
This is a small, early-stage study with only 40 participants, so results may not apply broadly. The benefit over speech therapy alone is uncertain.
