Clinical investigation of mild cognitive impairment in patients with Parkinson's disease
Bibliographic record
Abstract
Objective To describe the prevalence and neuropsychological character of mild cognitive impairment (MCI) associated with Parkinson' s disease(PD-MCI). Methods One hundred and three PD patients and a control group of 32 healthy old subjects were chosen. Psychometric assessment included the Mini Mental State Examination, the Dementia Rating Scale and a series of neuropsychol ogicaltests. The Hamilton Rating Scale of Depression was used to assess depression in PD patients. Results (1)Twenty-one (20.4%) PD patients was diagnosed with dementia, 45 (43.7%) had a MCI and only 37(35.9%) had no cognitive impairment; (2) Subjects with PD-MCI were older, had a later onset of the PD,and displayed more severe motor symptoms compared with those without cognitive impairment; (3) The prevalence and neuropsychological profile of PD-MCI were thought to correlate with the dominating side and subtype of Parkinsonian symptoms, for patients with left-sided dominant symptoms had a significantly higher chance of suffering MCI than those with right-sided dominant symptoms, the ratio being 74.2% vs 42.2%,χ<'2 =7. 589,P <0.05; The tremor-dominant group took less time than the mixed group for Stroop word test measurement ((80.8±39.9) s vs (94.4±30.0) s,t=3.332,P<0.01). Conclusion Identification of MCI is of important clinical significance, which helps to treat patients differently and thus predict the prognosis.

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.
