Effect of Stimulation of the Prefrontal Cortex on Language Production in Aphasic Patients

NCT02840370 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 19

No results posted yet for this study

Summary

The purpose of this study is to investigate whether transcranial direct current stimulation (tDCS) of the prefrontal cortex (PFC) influences lexical access and language production. The experimental paradigm will assess the impact of prefrontal stimulation by tDCS versus sham tDCS (S-tDCS) over the PFC of patients with chronic post-stroke aphasia during three language production tasks and a nonverbal executive functions task.

Conditions

  • Aphasia

Interventions

DEVICE

transcranial direct current stimulation

In tDCS, the prefrontal cortex is stimulated during 20minutes through a weak constant electric current (1-2 mA) through two electrodes in a non-invasive and painless manner.

DEVICE

Sham tDCS

S-tDCS refers to a control condition in which the subject will receive a brief current in the beginning in order to induce a similar sensation on the scalp as in tDCS, and then the stimulator remains off for the rest of the stimulation time.
