New brain test aims to unravel language confusion in dementia

This study is testing a new cognitive assessment called the ExéSem battery, designed to help doctors tell the difference between language problems caused by memory loss versus those caused by thinking difficulties. Researchers will enroll 140 people, including those with Alzheimer's disease, vascular cognitive impairment, a specific language disorder, and healthy volunteers. Participants will complete tasks like matching words to pictures and naming objects quickly, with results used to see if the battery can accurately identify the root cause of language issues.
