Zapping the brain to help stroke survivors speak again

This study tested whether a gentle, non-invasive brain stimulation technique called tDCS could make speech therapy more effective for people with aphasia (trouble understanding or using language) after a stroke. Twenty-three adults who were at least 6 months post-stroke received speech therapy paired with either real or fake (sham) brain stimulation. The goal was to see if the real stimulation improved their ability to understand sentences better than therapy alone.
