Simple blood test could revolutionize Alzheimer's diagnosis

NCT ID NCT04850053

First seen Mar 26, 2026

Summary

This study is testing a new blood test called the AD-seeds-detector that looks for specific protein clumps linked to Alzheimer's disease. Researchers will compare the test results from 1,500 people aged 55-75, including those with Alzheimer's, other dementias, and healthy individuals. The goal is to see if this test can diagnose Alzheimer's more accurately than current methods.
