Summary

This study tests whether a mild electrical current applied to the scalp (tDCS) can improve naming ability in people who have trouble speaking after a recent stroke. Twenty-eight adults with aphasia will receive either real or sham stimulation over five days. The goal is to see if the treatment helps them name pictures more accurately and quickly.

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)
What this could lead to: If it works, this could point toward a simple, non-invasive way to improve language recovery soon after a stroke.
What could go wrong: This is a small, early-phase trial with only 28 people, so results may not apply widely. Previous studies have been mixed, and any improvements may be short-lived.
