Correlation analysis of cognitive dysfunction and ischemic leukodystrophy in elderly patients
Bibliographic record
Abstract
Objective To study and analyze the correlation between cognitive dysfunction and ischemic leukodystrophy in elderly patients. Methods Eighty-eight elderly patients with ischemic leukodystrophy hospitalized in Pingmei Shenma Medical Group General Hospital from March 2016 to October 2017 were selected as research group. In addition, 30 healthy elderly patients who underwent physical examination in the same hospital were selscted as control group. The scores of the Montreal cognitive assessment (MoCA) of the two groups were analyzed and compared, and the relationship between the severity of disease and scores of MoCA scale was analyzed. Patients in research group were divided into cognitive dysfunction group (54 cases) and non-cognitive dysfunction group (34 cases), according to cognitive dysfunction development, for comparison on the basic data by multivariate Logistic regression analysis. Results The total score, visual space and executive function, attention, calculation, language, delayed recall and directional score of research group were lower than those of control group, and the differences were statistically significant (all P<0.05). The total score, delayed recall, directional score all showed a trend of gradually reduction in mild group, moderate group and medium group, contrast differences between groups were statistically significant (all P<0.05). The age, proportion of hypertension and diabetes in cognitive dysfunction group was higher than those in non-cognitive impairment group, and the difference was statistically significant (all P<0.05). Multivariate logistic regression analysis revealed that age, hypertension and diabetes were the independent risk factors of cognitive dysfunction in elderly patients with ischemic leukodystrophy (all P<0.05). Conclusions Cognitive dysfunction in the elderly is closely related to ischemic leukodystrophy, and with the increase of the severity of ischemic leukodystrophy, the more obvious the cognitive dysfunction is. Key words: Ischemic leukodystrophy; Cognitive dysfunction; Elderly; Correlation analysis

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.
