As a result, studies have begun focusing on risk factors for AD with the goal of identifying individuals with AD at the earliest possible stage. Such studies have found that individuals with Mild Cognitive Impairment (MCI) are at increased risk for AD and other forms of dementia. This study examines the potential mediating effect of a set of prospective risk factors, smoking and ApolipoproteinE (ApoE) genotype, on the incidence of MCI and AD. Although results of this study provide some preliminary evidence of an interaction, the study models presented here fail to reach significance. Additional studies are needed to confirm the hypothesis of an ApoE mediated relationship of smoking on MCI and AD. === 2031-01-01
