Brain & gene clues could unlock aphasia recovery mystery
NCT ID NCT06471127
First seen Jun 27, 2026 · Last updated Jul 08, 2026 · Updated 2 times
Summary
This study looks at how genes and brain scans can help predict recovery from aphasia, a language disorder that often follows a stroke. Researchers will enroll 90 adults aged 40-90 who have had a stroke and have trouble speaking or understanding language. By understanding these biological markers, the goal is to better forecast recovery and find new ways to treat aphasia in the future.
