Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 and older who have experienced a left hemisphere stroke and are fluent in English.

Probably not a fit

Patients with severe cognitive impairments, major psychiatric diseases, or contraindications to brain stimulation methods will not benefit from this study.

What this trial studies

This study investigates the effects of high-definition transcranial alternating current stimulation (HD-tACS) on language recovery in stroke survivors suffering from aphasia. Aphasia, often resulting from left hemisphere stroke, impairs communication abilities, and current treatments offer limited benefits. The study employs a double-blinded, sham-controlled design, combining HD-tACS with targeted language therapy to enhance phonological short-term memory. By restoring neural oscillatory activity and improving brain connectivity, the study aims to provide a novel approach to aphasia rehabilitation.

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 gone: While the use of tACS is relatively novel, preliminary studies suggest potential benefits in enhancing cognitive functions, indicating a promising avenue for aphasia treatment.
