Study Summary

The purpose of this research study is to evaluate adult children of parents with and without Alzheimer's disease which represent an ideal population for investigating the biological changes that precede the clinical onset of AD. The investigators will be imaging the brain to detect the presence of amyloid deposits (plaques in the brain). Amyloid is a protein that may be related to dementia of Alzheimer's disease (DAT).

Primary Outcome

the annual rate of CDR progression will accelerate due to the aging of the ACS cohort., and estimate that among \~375 ACS participants who either remain CDR 0 currently and will continue to be clinically assessed or will be the new future enrollees, a total of 45 individuals will progress to CDR\>0 by the end of next funding cycle.
