Transcranial Direct Current Stimulation (tDCS) With Verb Network Strengthening Treatment (VNeST) in Chronic Aphasia

The purpose of this study is to assess changes in language abilities of participants with chronic, post-stroke aphasia following an 8-week therapy period combined with brain stimulation. The investigators use a stimulation method called transcranial direct current stimulation (tDCS). The investigators cover two electrodes in damp sponges, place them on the scalp, and pass a weak electrical current between them. Some of this current passes through the brain and can change brain activity. One electrode is placed over language areas a bit above and in front of the left ear. The other is placed on the forehead above the right eye. Stimulation is provided twice a week for 8 weeks during aphasia therapy. The investigators believe that this stimulation may increase the effectiveness of therapy.
