What this trial studies

This study aims to enhance language rehabilitation outcomes for individuals with post-stroke aphasia by combining traditional speech-language therapy with transcranial direct current stimulation (tDCS). The research focuses on individuals who have experienced a left hemisphere stroke and are at least six months post-stroke. By applying excitatory brain stimulation during anomia treatment, the study seeks to improve word retrieval abilities and investigate the underlying brain connectivity changes associated with recovery. The ultimate goal is to optimize therapeutic approaches for better language processing in patients with aphasia.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 80 who have post-stroke aphasia resulting from a single left hemisphere stroke and can speak English as their native language.

Not a fit: Patients with severe auditory comprehension deficits or those with co-occurring neurological or major mental health disorders may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly improve language recovery and quality of life for patients with post-stroke aphasia.

How similar studies have performed: While the use of tDCS in conjunction with language therapy is a relatively novel approach, preliminary studies have shown promising results in enhancing rehabilitation outcomes for similar conditions.
