The goal of this observational study is to learn about neuroimage and biomarkers in the Alzheimer's continuum. The main questions it aims to answer are:
* How is the neurovascular coupling during AD pathogenesis?
* How is the pattern/mapping of alterations in AD biomarkers? Participants will be observed and visit the research center annually to perform multi-modal MRI, PET, neuropsychological tests, and blood tests.
