Abstract

fetched live from OpenAlex

BACKGROUND: Conflicting results have been reported about the status of diabetes mellitus as a risk for Alzheimer's disease. We investigated the relationship between diabetes and incident dementia (including Alzheimer's disease and vascular cognitive impairment) in a 5-year longitudinal study. METHODS: Secondary analysis of the Canadian Study of Health and Aging, a representative cohort study of dementia in older Canadians. RESULTS: 5,574 subjects without cognitive impairment at baseline participated in 5-year follow-up. Diabetes mellitus at baseline was associated with incident vascular cognitive impairment (RR: 1.62; 95% CI: 1.12-2.33) and its subtypes, vascular dementia (RR: 2.03; 95% CI: 1.15-3.57), and vascular cognitive impairment not dementia (RR: 1.68; 95% CI: 1.01-2.78). Diabetes was not associated with mixed Alzheimer's/vascular dementia (RR: 0.87; 95% CI: 0.34-2.21), incident Alzheimer's disease (RR: 1.30; 95% CI: 0.83-2.03) or all dementias (RR: 1.26; 95% CI: 0.90-1.76). CONCLUSIONS: Despite increased recognition of the role of vascular factors in Alzheimer's disease, we did not find an association between diabetes and incident Alzheimer's disease, even though diabetes was associated with incident vascular cognitive impairment.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
