Abstract

fetched live from OpenAlex

AIMS: This study aimed to assess the longitudinal changes in cognitive function and associated factors in older patients with type 1 diabetes mellitus without dementia. MATERIALS AND METHODS: Older patients above 65 years of age with type 1 diabetes mellitus and without dementia were included in this study. They were assessed using the Mini-Mental State Examination and Montreal Cognitive Assessment, Japanese version, at baseline and 3 years after. Cognitive decline was defined as a reduction of two or more points in the total Montreal Cognitive Assessment score over 3 years. Baseline diabetes-related factors were compared between the cognitive decrement and non-decrement groups to identify risk factors associated with cognitive impairment. RESULTS: Twenty-eight patients aged 71.5 ± 4.0 years were included. Total scores for the Mini-Mental State Examination and the Montreal Cognitive Assessment (Japanese version) at baseline and after 3 years of follow-up showed no significant changes (P = 0.38, P = 0.26). Delayed recall sub-scores of both tests were significantly lower after 3 years compared to their corresponding levels at baseline (P = 0.007, P = 0.04); 32% experienced impaired cognition after 3 years compared to baseline examination. Decline in total Montreal Cognitive Assessment score was significantly associated with the onset age (β = 0.54, P = 0.026) and duration of type-1 diabetes mellitus (β = -4.77, P = 0.026). CONCLUSIONS: Patients with type-1 diabetes mellitus without dementia experience a progressive decline in memory over time. Long durations of type-1 diabetes mellitus are associated with cognitive decline even without dementia.

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.
