This study is testing if combining transcranial direct current stimulation (tDCS) with Verb Network Strengthening Treatment (VNeST) can improve language abilities in people with chronic aphasia (difficulty with language after a stroke). tDCS involves placing two damp sponges on your scalp and passing a weak electrical current between them to change brain activity. One sponge is placed near language areas above your left ear, and the other on your forehead above your right eye. You would receive tDCS during the first 20 minutes of your twice-weekly VNeST therapy sessions for 8 weeks. The study aims to see if this combination helps you produce more correct information in your speech. They plan to enroll 30 participants, including those with post-stroke aphasia and healthy volunteers.

Study design

This is an interventional study that plans to enroll 30 participants. It compares active tDCS with sham (inactive) tDCS during speech therapy, and the therapist will not know which type of stimulation you are receiving.

What's involved

You would complete four behavioral assessments and four brain scans (MRI). Two assessments and scans happen before treatment, one immediately after, and one 8 weeks later. Therapy sessions are 60 minutes, twice weekly for 8 weeks, and you cannot receive other speech therapy during the study (about 20 weeks).

Compensation

Not stated in the trial record.

Follow-up

Your language abilities will be assessed immediately after treatment and again 8 weeks after treatment.
