Medical College of Wisconsin

This study will assess the effects of transcranial alternating current stimulation (tACS) on language recovery after stroke.
Description
Aphasia is a debilitating disorder, typically resulting from damage to the left hemisphere, that can impair a range of communication abilities, including language production and comprehension, reading, and writing. Approximately 180,000 new cases of aphasia are identified per year, and approximately 1 million or 1 in 250 are living with aphasia in the United States.
