Abstract

Age and APOE are the most robust risk factors for dementia and cognitive decline, but the underlying neurobiology remains unclear. We examined the extent to which the hallmark pathologies of Alzheimer's disease, Lewy body disease, and cerebrovascular diseases account for the association of age and APOE with decline in episodic memory versus nonepisodic cognitive abilities. Up to 20 waves of longitudinal cognitive data were collected from 858 autopsied participants in 2 ongoing clinical-pathologic cohort studies of aging. Neuropathologic examinations quantified measures of beta amyloid (Aβ) plaque, mesial temporal and neocortical neurofibrillary tangles, macro- and microinfarcts, and neocortical Lewy bodies. Random coefficient models estimated person-specific slopes of decline in episodic memory and nonepisodic cognition. Path analysis examined the relation of age, APOE, and the 6 pathologic indices to the slopes of cognitive decline. The effect of age on decline in episodic memory was mediated by Aβ, mesial temporal and neocortical tau tangles, and macroscopic infarcts; age on decline in nonepisodic cognition was mediated by Aβ, neocortical tangles, and macroscopic infarcts. The effect of APOE on decline in episodic memory was mediated by Aβ, mesial temporal and neocortical tangles, and neocortical Lewy bodies; APOE on nonepisodic cognition was mediated by Aβ, neocortical tangles, and neocortical Lewy bodies. There were no direct effects of age and APOE on decline after accounting for these pathologic pathways.

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.
