APOE genotypes as a risk factor for age-dependent accumulation of cerebrovascular disease in older adults.

ABSTRACT:

Introduction

Apolipoprotein E (APOE) is a susceptibility gene for late-onset Alzheimer's disease neuropathology; less is known about the relationship between APOE and cerebrovascular disease (CVD) neuropathology.

Methods

We investigated associations of APOE status with arteriolosclerosis, macroinfarcts and microinfarcts, and atherosclerosis in 1383 adults (65.9-108.2 years at death) with and without dementia. Excluding ε2/ε4 carriers, multivariable regressions for each CVD-related neuropathology compared ε4 and ε2 carriers to ε3/ε3 carriers adjusting for confounders including age and Alzheimer's neuropathology.

Results

Three hundred forty-two individuals (24.7%; ∼87.7 years at death; 39.9% nondemented) were ε3/ε4 or ε4/ε4, and 180 (13.0%; ∼89.9 years at death; 66.6% n
