Abstract

OBJECTIVE: To assess the contribution of dementia-related neuropathologic lesions to age-related and disease-related change in cognitive function. METHODS: A total of 354 Catholic nuns, priests, and brothers had annual clinical evaluations for up to 13 years, died, and underwent brain autopsy. The clinical evaluations included detailed testing of cognitive function from which previously established composite measures of global cognition and specific cognitive functions were derived. As part of a uniform neuropathologic evaluation, the density of neurofibrillary tangles was summarized in a composite measure and the presence of Lewy bodies and gross and microscopic cerebral infarction was noted. RESULTS: During follow-up, rate of global cognitive decline was gradual at first and then more than quadrupled in the last 4 to 5 years of life consistent with the onset of progressive dementia. Neurofibrillary tangles, cerebral infarction, and neocortical Lewy bodies all contributed to gradual age-related cognitive decline and little age-related decline was evident in the absence of these lesions. Neurofibrillary tangles and neocortical Lewy bodies contributed to precipitous disease-related cognitive decline, but substantial disease-related decline was evident even in the absence of these lesions. CONCLUSION: Mild age-related decline in cognitive function is mainly due to the neuropathologic lesions traditionally associated with dementia.

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.
