Using brain stimulation to improve language recovery in stroke patients with aphasia

Exogenous Tuning of Neural Oscillations as a Mode of Treatment in Post-stroke Aphasia

Not applicable Interventional Medical College of Wisconsin · NCT04375722

This study is testing if a new brain stimulation technique can help stroke patients with aphasia recover their language skills better than regular therapy alone.

What this trial studies

This study investigates the effects of transcranial alternating current stimulation (tACS) on language recovery in individuals with post-stroke aphasia. Aphasia, a communication disorder resulting from brain damage, affects language production and comprehension. The study aims to enhance traditional speech and language therapies by applying high-definition tACS to restore neural activity and improve connectivity in the brain's language network. Participants include both stroke patients with aphasia and healthy controls, with the goal of assessing the efficacy of tACS in facilitating language recovery.

Who should consider this trial

Good fit: Ideal candidates include right-handed adults aged 18 and older who are fluent in English and have been diagnosed with post-stroke aphasia.

Not a fit: Patients with severe cognitive impairments, major psychiatric disorders, or contraindications to tACS or MRI may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly enhance language recovery and communication abilities in stroke patients with aphasia.

How similar studies have performed: Other studies have shown promising results with brain stimulation techniques in improving language functions, suggesting potential for success in this novel approach.
