Ruijin Neurobank of Alzheimer's Disease and Dementia

Summary

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.
