Feasibility study of the Montreal cognitive assessment in detecting subcortcial vascular cognitive impairment-no dementia
Bibliographic record
Abstract
Objective To explore feasibility study of the Montreal cognitive assessment (MoCA) in detecting subcortcial vascular cognitive impairment-no dementia(VaCIND-S). Methods Seventy-five Chinese Han were assessed by the MoCA and MMSE.40 met criteria for VaCIND -S and 35 were considered cognitively normal. ROC curve analyses were performed to determine optimal sensitivity and specificity. Results No differences were found between groups on age, gender, education degrees.According to their MoCA scores, cognitive impairments including memory, visuospatial, executive function, attention, language, and orientation sub-scores in VaCIND-S ((0.43±1.01), (2.21±1.19), (2.11±1.13), (4.66±1.48), (4.42±1.31), (4.86±1.12)) significantly decreased compared with those in controls((2.93±1.36), (3.29±1.06), (3.53±0.93), (5.94±0.24), (5.44±0.71), (5.80±0.48)) (P<0.05). The MMSE scale was insensitive to cognitive impairment as compared with MoCA scale. Using cut-off score of 23.5, the MoCA exhibited excellent sensitivity (0.971) and specificity (0.789). Conclusion MoCA is a more sensitive instrument than the MMSE for the detection of VaCIND-S and warrants further investigation regarding its applicability in large and varying ethnic population.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
