Semantic Recognition Task (SRT) in Alzheimer Disease

This study is testing a new memory assessment tool called the Semantic Recognition Task (SRT) — a test that measures how well a person recognizes and understands word meanings — in people who have already undergone biomarker testing for Alzheimer's disease. The goal is to see whether the SRT can help detect Alzheimer's disease or track its progression, and whether it performs differently in people whose biomarker tests were positive versus negative. **You may be eligible if...** - You have already had biomarker testing for Alzheimer's disease (whether the result was positive or negative) - You are able to read **You may NOT be eligible if...** - You are unable to read (illiteracy is an exclusion criterion, as the task requires reading) Talk to your doctor to see if this trial is right for you.
