Is this trial a fit for you?

Likely a good fit

Ideal candidates include right-handed adults aged 18 and older who have been diagnosed with a left hemisphere stroke and are fluent in English.

Probably not a fit

Patients with severe cognitive impairments, unstable psychiatric conditions, or certain medical implants may not benefit from this study.

What this trial studies

This study investigates the impact of Transcranial Magnetic Stimulation (TMS) on individuals who have experienced a stroke and suffer from aphasia, as well as healthy participants. It employs a randomized, within-subject design to assess the effects of TMS on semantic and phonological language processes, both in isolation and in interaction with other cognitive functions. The study aims to identify how TMS can influence language processing by targeting specific brain regions associated with these functions, based on prior neuroimaging and neuropsychological research.

Why it matters

Potential benefit: If successful, this study could lead to improved therapeutic strategies for enhancing language recovery in stroke survivors with aphasia.

How similar studies have gone: Previous studies using TMS for language processing have shown promising results, suggesting that this approach may be effective in enhancing language recovery.
