Diabetes mellitus and risk of Alzheimer disease and decline in cognitive function

Abstract

BACKGROUND: Few prospective studies have assessed diabetes mellitus as a risk factor for incident Alzheimer disease (AD) and decline in cognitive function. OBJECTIVE: To evaluate the association of diabetes mellitus with risk of AD and change in different cognitive systems. DESIGN: Longitudinal cohort study. PARTICIPANTS: For up to 9 years, 824 older (those >55 years) Catholic nuns, priests, and brothers underwent detailed annual clinical evaluations. MAIN OUTCOME MEASURES: Clinically diagnosed AD and change in global and specific measures of cognitive function. RESULTS: Diabetes mellitus was present in 127 (15.4%) of the participants. During a mean of 5.5 years of observation, 151 persons developed AD. In a proportional hazards model adjusted for age, sex, and educational level, those with diabetes mellitus had a 65% increase in the risk of developing AD compared with those without diabetes mellitus (hazard ratio, 1.65; 95% confidence interval, 1.10-2.47). In random effects models, diabetes mellitus was associated with lower levels of global cognition, episodic memory, semantic memory, working memory, and visuospatial ability at baseline. Diabetes mellitus was associated with a 44% greater rate of decline in perceptual speed (P =.02), but not in other cognitive systems. CONCLUSIONS: Diabetes mellitus may be associated with an increased risk of developing AD and may affect cognitive systems differentially.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Diabetes is associated with increased risk for Alzheimer disease.

    “and increased risk for Alzheimer disease89,90, are observed.”

    From Sleep Deprivation and Circadian Disruption (2015) · cites this paper as [89]

  • Eight studies reported a variety of other cognitive tests, most of them reporting greater or equal cognitive change for the diabetic participants, and some but not all of the tests detected a significant difference between the groups with and without diabetes.

    “Eight studies reported a variety of other cognitive tests, most of them reporting greater or equal cognitive change for the diabetic participants (Table 1) [46, 49, 51, 58, 63, 66, 69, 70]. Some, but not all of the tests detected a significant difference between the groups with and without diabetes.”

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.
