Abstract

BACKGROUND: No previous autopsy-controlled, prospective, and population-based studies are available on the prevalence of AD in very elderly people. OBJECTIVE: To study the point prevalence of neuropathologically defined AD in a population of people at least 85 years of age, stratified according to their APOE genotype. METHODS: A population-based sample of 532 (of a total population of 601) elderly Finnish individuals, aged 85 years or more, were clinically tested for dementia in 1991 (with follow-up studies of the survivors in 1994, 1996, and 1999) and genotyped for APOE. An autopsy involving neuropathologic diagnosis of AD according to modified consensus criteria was performed in 118 of 198 deceased subjects who had been demented on April 1, 1991, and in 62 of 201 nondemented individuals. RESULTS: The prevalence of neuropathologically defined AD was 33%, whereas the prevalence of clinically diagnosed AD was 16%. There was a highly significant (p < 0.001) association between the APOE epsilon4 allele and AD: Sixty-three percent of APOE epsilon4 carriers and 20% of noncarriers had neuropathologic AD. The respective figures in subjects aged 90 years or more were 71 and 22%. CONCLUSIONS: The prevalence of neuropathologically defined AD is higher than that reported in most previous studies based on clinical diagnosis. The discrepancy between the neuropathologic and clinical diagnoses of AD in very elderly subjects may affect the results of population-based studies. The APOE genotype has a strong effect on the prevalence of neuropathologically defined AD, even after 90 years of age.

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.
