Transcranial Direct Current Stimulation and Rehabilitation to Ameliorate Impairments in Neurocognition After Stroke

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.

Detailed Description

This is a double-blind, sham-controlled study in which subjects with cognitive impairment after stroke will undergo neuropsychological testing before and after receiving 5 semi-consecutive daily sessions of real or sham transcranial direct current stimulation (tDCS) paired with cognitive therapy. Subjects will have experienced a stroke within 3 months of enrollment and will be undergoing inpatient rehabilitation at Penn Institute for Rehabilitation Medicine. Neuropsychological testing will be repeated immediately after completion of stimulation and 3-, 12- and 24- months following completion of treatment. The investigators will examine changes in cognitive performance induced by tDCS + cognitive therapy compared to sham tDCS + cognitive therapy. This study will combine knowledge gained from our behavioral, clinical and sociodemographic data in order to determine the relative degrees to which these properties predict whether persons with post-stroke cognitive impairment will respond to intervention.
