NCT ID NCT07238049
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study is testing whether simple blood tests can accurately diagnose dementia in everyday clinic settings. Over 3,000 people aged 45 and older with memory problems will give blood samples and answer questionnaires. Researchers will check how reliable and acceptable these blood tests are compared to standard methods like spinal taps or brain scans.
