ClinConnect Summary

This clinical trial is exploring the effects of combining a type of brain stimulation called transcranial Direct Current Stimulation (tDCS) with traditional speech therapy for people recovering from a specific type of language difficulty known as Broca's Aphasia, which often occurs after a stroke. The goal is to see if this combination can help the brain adapt and improve communication skills better than speech therapy alone. Researchers will use imaging techniques like MRI to monitor changes in the brain during the study.

To participate, individuals must be between the ages of 65 and 74, have had a single stroke affecting the left side of the brain, and be right-handed Cantonese speakers. They should also be able to understand instructions for tasks. Unfortunately, those with other neurological conditions, specific types of aphasia, or certain medical devices or conditions will not be eligible. Participants can expect to receive both tDCS and speech therapy while contributing to valuable research that may improve treatment for aphasia in the future.
