Tau Levels in Donated Blood

This study uses a simple blood test to quickly detect Alzheimer's-related brain changes (amyloid plaques). It may help people with memory concerns avoid a more invasive PET scan and get answers faster.

This study is testing whether a simple blood test can help doctors diagnose Alzheimer's disease earlier and more accurately. It's for people who are having memory or thinking problems and are visiting a memory clinic.

This study looks at blood tests to help diagnose and track brain diseases (like Alzheimer's) or mental health conditions. It compares patients to healthy volunteers to find better ways to detect and monitor these illnesses.

This study looks at different fluids from the body, like blood and tears, to find better ways to diagnose and track alzheimer's and related dementias. It compares people with these conditions to healthy volunteers to see what biological markers differ.

This study is testing whether a simple blood test can help diagnose Alzheimer's disease and predict how the disease will progress. If you have memory or thinking problems that have been getting worse, you may be able to join.

This study is testing a simple blood test (p-Tau217) as a possible way to diagnose Alzheimer's disease. If it works, it might replace the need for a spinal tap. The results will be compared with the usual spinal fluid markers.
