Abstract
Objective To study the application of Montreal cognitive assessment (MoCA) in vascular cognitive impairment (VCI) ,and make a benchmark for a cutoff score.Methods 60 healthy elderly controls and 50 patients meeting the clinical criteria for VCI were tested by MoCA and mini-mental state examination(MMSE) .The validities of MoCA and MMSE were compared.The age,sex,education and nature of the work in the two groups were stratified and analyzed.Results Education and nature of the work had statistical differences between MoCA and MMSE.In persons whose educa-tion level was below junior high school,the cutoff score for MoCA was ≥22,and the sensitivity was 83.3% ,which was higher than that for MMSE sensitivity (46.7% ) ; in those whose education level was above junior high school,the cutoff score for MoCA was ≥25,the sensitivity was 85% ,which was higher than that for MMSE (50% ) .Conclusion MoCA has a higher screening sensitivity for VCI than MMSE do.Adjustment in the cutoff scores would improve the detection of VCI by reducing false negativity.MoCA scores should be used to identify current cognitive difficulties but not be used to make formal diagnosis.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
