Effects of a Combination of Transcranial Direct Stimulation (tDCS) and Behavioral Intervention in Non-fluent Aphasia
In Brief
A clinical study evaluating Transcranial direct current stimulation for Aphasia. Completed, enrolled 3 participants across 1 site.
Detailed Summary
We hypothesize patients who have difficulty with word recall (naming pictures) due to a stroke will experience greater benefit in word recall after receiving a combination of transcranial direct current stimulation (tDCS) and traditional behavioral treatment. This study will investigate the effects of the timing of tDCS in relationship to the behavioral treatment to determine the most optimal protocol. Transcranial direct current stimulation involves placing two electrodes on your scalp and sending a very small electrical current to excite the brain cells of the target site.

Timeline
Interventions
Transcranial direct current stimulation (tDCS) is a non-invasive neuromodulation tool that presents a low current that induces bi-directional polarity-dependent changes in the cortex to facilitate focal, prolonged shifts in cortical excitability at or around the time stimulation is provided. Anodal tDCS (a-tDCS), in which the positively charged electrode is placed over the targeted cortical region, has been shown to increase cortical excitability (upregulation), similar to long-term potentiation (LTP). Combining a-tDCS with behavioral-based approaches has been suggested to enhance the learning process and increase the likelihood of retention.
