Explore the utility of MoCA in the US-residing Chinese-speaking population Lead Investigator: Clara Li Institution : Mount Sinai E-Mail : clara.li@mssm.edu Proposal ID : 1588 Proposal Description: 1. Explore the optimal cutoff scores to detect MCI and AD in US-residing Chinese-speaking individuals using ROC analysis and compare the results to those in other racial/ethnic groups, including non-overseas-residing Chinese. 2. Explore if the MoCA subtests maintain the proposed structure in the Chinese-speaking population using principle component analysis. 3. Explore if MoCA total score and/or subtest scores are predictive of disease progression (i.e., new onset of MCI/AD and MCI converting to AD)
