Summary

This study tests whether a gentle electrical current applied to the brain can make speech therapy more effective for people with chronic aphasia (trouble speaking or understanding language) after a stroke. About 50 adults who had a stroke at least six months ago will receive either real or fake brain stimulation during 15 speech therapy sessions. Researchers will measure improvements in picture naming and conversation skills right after treatment and again three months later.
