The goal of this prospective, multicenter, watch-and-measure (no experimental treatment required) cohort study is to measure the screening performance of blood-based biomarkers for Alzheimer's disease (AD) in a real-world community screening setting, and to establish the population baseline levels and reference intervals of these biomarkers in Chinese older adults. The main questions it aims to answer is: What is the clinical screening value of blood biomarkers (phosphorylated tau 217 to amyloid β 42 ratio \[pTau217/Aβ42\] and glial fibrillary acidic protein \[GFAP\]) for AD among community-dwelling older adults?

This is an observational study. You are not assigned a new experimental drug. Researchers measure what already happens in your care or in daily life.
Phase labels are FDA/ICH categories applied to the registry Phase field. They are not a finding that this study succeeded.
This listing is observational (StudyType). The registry does not assign a new experimental drug as the study intervention.
They plan to enroll about 3,000 people at 4 sites. Taking part typically means study visits and measurements plus check-ins.
