Summary

This study tests whether a gentle, non-invasive electrical brain stimulation (tACS) can improve working memory in people who have memory problems after a stroke. 24 participants will receive either real or fake stimulation for 40 minutes a day for 5 days, alongside cognitive therapy. Researchers will measure memory performance and brain activity before and after treatment.

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 it works, this could point toward a non-drug way to help stroke survivors regain memory and thinking skills.
What could go wrong: This is a very small, early-stage trial with only 24 people. The effect may be small or not last, and results may not apply to all stroke patients.
