Enhancing speech-language treatment for stroke patients with aphasia using brain stimulation

Targeted Transcranial Direct Current Stimulation to Enhance Speech-Language Treatment Outcome in Persons With Chronic Post-Stroke Aphasia

Not applicable Interventional University of New Mexico · NCT04432883

This study is testing if adding brain stimulation to speech therapy can help stroke survivors with aphasia improve their language skills better than just therapy alone.

What this trial studies

This study aims to recruit 62 patients who are at least one year post-stroke and have developed aphasia as a result. Participants will undergo four assessment sessions and 15 treatment sessions involving targeted transcranial direct current stimulation (tDCS) to the right Inferior Frontal Gyrus, combined with a specific language therapy. The study will compare the effectiveness of active tDCS versus sham stimulation in improving language outcomes. Assessments will be conducted before treatment, immediately after, and at a three-month follow-up to evaluate the impact of the intervention.

Who should consider this trial

Good fit: Ideal candidates are adults aged 25-85 who are more than six months post-stroke and have a diagnosis of aphasia.

Not a fit: Patients with comorbid neurological diseases or significant mood disorders may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly improve communication abilities in patients with chronic post-stroke aphasia.

How similar studies have performed: Other studies have shown promise in using brain stimulation to enhance language therapy outcomes, suggesting this approach may be effective.
