Transcranial Direct Current Stimulation Investigations of Language Processing in Aphasia

NCT04041986 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 25

Summary

This study proposes to use transcranial direct current stimulation (tDCS) in patients with chronic strokes and aphasia in order to characterize and enhance the mechanisms of language recovery following injury. Prior to enrollment subjects will undergo six "site-finding' sessions involving various placements of positively charged (anodal), negatively charged (cathodal), and sham stimulation over the damaged and intact hemispheres of the brain, along with standard tests of language. Subjects who are found to experience a transient improvement in language ability in this initial experiment will participate in an incomplete cross-over design study to determine if 10 sessions of tDCS stimulation lead to prolonged language benefit when delivered to the hemisphere and at the polarity shown previously to respond best to stimulation.

  • Aphasia

Interventions

DEVICE

Transcranial Direct Current Stimulation (tDCS)

Transcranial direct current stimulation (tDCS) is a form of non-invasive neuromodulation that uses constant, low (1-2mA), direct current delivered via electrodes on the head.
