A? and Tau seeds have the potential to serve as biomarkers for AD. The AD-seeds-detector could detect small quantities of A? and Tau seeds by taking advantage of their ability to nucleate and enhance aggregation, enabling a very high amplification of the signal. This study examines the effectiveness of using the AD-seeds-detector as a novel technique for discriminating AD from cognitively normal control and non-AD dementia by detecting small A? and Tau seeds in plasma. This will be an observational study aiming at using the AD-seeds-detector to detect minute amounts of A? and Tau seeds in plasma as novel biomarkers with high sensitivity and specificity for the accurate diagnosis of AD. To achieve this goal, the investigators will conduct two studies using the AD-seeds-detector to detect the A? and Tau seeds in the plasma samples. Study one: A single-center cohort that consists of well-characterized AD patients (n=150), cognitively normal controls (n=100) and non-AD dementia patients (n=50). Study two: A multi-center cohort with well-characterized AD patients (n=400), cognitively normal controls (n=400) and non-AD dementia patients (n=400).
