Abstract

This pilot study will test the central hypothesis that vision impairments is a “second hit” that potentiates the risk of cognitive decline and dementia among those that carry the APOE ε4 allele. This hypothesis will be tested using data from the nationally-representative Health and Retirement Study and its sub-study, the Aging, Demographics and Memory Study.
