Transcranial Direct Current Stimulation and Rehabilitation to Ameliorate Impairments in Neurocognition After Stroke
Sponsor: University of Pennsylvania
Summary
The purpose of this study is to determine whether a non-invasive brain stimulation technique, transcranial direct current stimulation (tDCS), combined with traditional cognitive therapy will improve cognitive function in patients with subacute stroke.

tDCS
tDCS is a type of non-invasive brain stimulation in which small electrical currents are applied to the scalp via 2 electrodes. During sham stimulation, the current, 2 mA, will be delivered for a short amount of time and then turn-off. To deliver the current, electrodes that are placed in saline soaked sponges. They will be attached to the left side of your head; they will be held in place with an elastic cap. For both real and sham stimulation the electrodes will be placed on the scalp. Most people cannot tell the difference between real and sham stimulation.

Cognitive Therapy
During both the treatment and the sham intervention, participants will undero cognitive therapy training by performing the NBack task. In this sequential letter memory exercise participants are presented with sequential stimuli in the form of a series of letters. For each new stimulus they are asked to indicate if the current stimulus matches the stimulus from 2 trials prior. This exercise stimulates cognitive demand in working memory, executive function and attention and is correlated with dorsolateral prefrontal cortex activity.
