About this trial

The CROWN-I Study is an observational study to learn about molecular features of Alzheimer's disease (AD) and mild cognitive impairment (MCI). The primary objective is to identify the molecular and genetic modules that differentiate patient subtypes and predict progression of AD. Participants will visit clinical sites to donate samples multiple times and perform virtual and in-person clinical assessments.
