Enhancing Aphasia Therapy With Anodal Transcranial Direct Current Stimulation in Chronic Stroke Patients
This is a randomized, crossover design trial that will compare how anodal transcranial
direct current stimulation (tDCS) versus sham tDCS administered during multiple sessions of
scripting therapy affects the acquisition and retention of trained scripts.

4. Fluent English speaker prior to stroke
5. Right-handed prior to stroke
6. Ability to give informed consent and understand the tasks involved.
Exclusion Criteria:

cerebral artery territory
2. Imaging unavailable
3. Large middle cerebral artery infarct involving entire inferior division
(temporo-parietal) territory
4. History of dementia prior to the stroke
5. History of seizure, prior electroconvulsive therapy, deep brain stimulators, or brain
