Cardiovascular Disease and Changes in Intellectual Functioning From Middle to Old Age
Abstract
The relationship between cardiovascular disease (CVD) and intellectual functioning was investigated using a categorical division of a previously studied cross-sequential sample into groups with and without clinical cardiovascular diagnoses during the period of assessment. CVD was found to be a significant predictor of performance on several cognitive subtests, even when chronological age (cohort) was included as a factor in the statistical analysis. However, the pattern of effects was not completely consistent with a model relating CVD to intellectual decrement over time. Further breakdown of subjects into CVD subgroups (e.g., hypertension) showed the CVD effect to be specific to some subgroups, but did not fully resolve the inconsistency with the decremental model. The results also suggest CVD to be one of the factors leading to subsequent attrition from the sequential sample.

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.
