4 Allele Increases the Odds of Chronic Cerebral Infection Detected at Autopsy in Older Persons
4 allele to clinical stroke and to vascular changes on magnetic resonance imaging have been conflicting. Little data are available regarding the relation of apoE 4 to cerebral infarctions documented on postmortem examination.4 allele in 214 deceased members of the Religious Orders Study, a longitudinal clinical-pathologic study of aging and Alzheimer disease. The apoE genotype was determined using DNA from lymphocytes. Brains were removed a median of 5 hours (interquartile range, 5.5) after death. At postmortem examination, age, location, and size of macroscopic chronic cerebral infarctions were recorded from 1-cm coronal slabs after paraformaldehyde fixation. We also examined 20-µm paraffin-embedded sections of midfrontal and calcarine cortex for amyloid angiopathy on a scale of 1 to 4.4 allele and 76 (35.5%) exhibited cerebral infarctions. More than 74% of the subjects exhibited amyloid angiopathy with a mean score of 1.4±1.2. After controlling for age and sex, apoE 4 increased the odds of cerebral infarction by 2.3-fold (95% CI, 1.2 to 4.2). apoE 4 increased the odds of cortical 3.2-fold (95% CI, 1.3 to 7.7) and subcortical infarctions 2.3-fold (95% CI, 1.2 to 4.5). The effect was unchanged after accounting for amyloid angiopathy.4 increases the odds of chronic cerebral infarction detected at autopsy in older persons.
