Abstract

BACKGROUND: The epsilon 4 allele of apolipoprotein E has been associated with an increased risk of late-onset Alzheimer's disease. In a cohort of elderly subjects we prospectively investigated the relation between the apolipoprotein E genotype, dementia, and the accumulation of beta-amyloid protein in the cerebral cortex. METHODS: Autopsy involving neuropathological analysis and DNA analysis of frozen blood samples were performed in 92 of 271 persons who were at least 85 years of age, who had been living in Vantaa, Finland, on April 1, 1991, and who had died between that time and the end of 1993. All subjects had been tested for dementia. Apolipoprotein E genotyping was done with a solid-phase minisequencing technique. The percentage of the cortex occupied by methenamine silver-stained plaques was used as an estimate of the extent of beta-amyloid protein deposition. RESULTS: The frequency of the epsilon 4 allele was significantly higher in the subjects with Alzheimer's disease than in the subjects without dementia (30 percent vs. 8 percent, P < 0.001). There was a greater accumulation of beta-amyloid protein in the brain and more neurofibrillary tangles in the subjects with the epsilon 4 allele than in those without it (P < 0.001). The deposition of beta-amyloid protein varied according to the genotype in both the subjects with dementia and those without dementia: it was lowest in those with the epsilon 2/epsilon 3 genotype, intermediate in those with the epsilon 3/epsilon 3 genotype, and highest in those with the epsilon 3/epsilon 4 genotype. A single subject had the epsilon 4/epsilon 4 genotype and had dementia. CONCLUSIONS: The epsilon 4 allele of apolipoprotein E is significantly associated with Alzheimer's disease. Even in elderly subjects without dementia, the apolipoprotein E genotype is related to the degree of deposition of beta-amyloid protein in the cerebral cortex.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
