Association between plasma homocysteine and cognitive dysfunction in patients with Parkinson's disease
Bibliographic record
Abstract
Objective To study the association between the level of plasma homocysteine(Hcy) and the cognitive dysfunction in patients with Parkinson's disease(PD).Methods Total 156 subjects were enrolled, including 50 unrelated healthy controls and 106 patients with PD. The basic information, disease situation and cognitive function of patients with PD were investigated and the plasma concentrations of Hcy, folic acid and vitamin B12 were detected in each subject. The relationship between plasma Hcy levels and the cognitive function was assessed.Results The plasma Hcy concentrations of cognitive dysfunction group were higher than those of normal cognitive group [(21.5±5.1)μmmol/L vs(14.7±4.7)μmmol/L, P 0.05] and there were no differences in plasma concentrations of folic acid and vitamin B12 among the groups. The scores of the Mini-mental state examination(MMSE) and Montreal cognitive assessment(MoCA) all showed significant correlations with plasma Hcy in patients with PD.Conclusion The elevated plasma Hcy level is significantly associated with the cognitive dysfunction.The increase of plasma Hcy maybe one of the main important risk factors of cognitive dysfunction in PD patients.

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.
