Improving Aphasia Using Electrical Brain Stimulation

Active transcranial direct current stimulation will be delivered using a Soterix mini-CT device. Participants receiving this treatment will be administered 2 milliamperes (mA) of current for 20 minutes/session for 10 sessions.

Sham transcranial direct current stimulation will be delivered using a Soterix mini-CT device. Participants receiving this treatment will be administered 2 milliamperes (mA) of current for 1 minute to simulate the experience of tDCS, after which the current will be ramped down to zero for the remaining 19 minutes of the session. Participants in this arm will receive sham stimulation for 10 sessions.

This is a specific type of speech-language therapy that focuses on simultaneously improving auditory comprehension and behavioral attention. All study participants will receive 10 sessions of this treatment.
