The predictive value of early cognitive assessment for cognitive function after 3-6 months in acute ischemic stroke patients
Bibliographic record
Abstract
Objective To explore the predictive value of short term cognitive assessment in the acute phase of ischemic stroke for 3-6 months after stroke. Methods The demographic data, vascular risk factors, clinical and imaging data of 254 patients with acute ischemic stroke from August 2016 to December 2017 were prospectively registered.The cognitive function was assessed by Mini-mental state examination (MMSE) and Montreal cognitive assessment (MoCA) 3 weeks after stroke onset.Comprehensive cognitive function assessment was performed after 3-6 months of stroke.Multiple factor Logistic regression was used to screen the independent risk factors of cognitive domain and overall cognitive function in 3-6 months. Results Totally 254 consecutive patients with acute ischemic stroke were enrolled.Combined with the inclusion and exclusion criteria, 161 patients completed the baseline cognitive assessment, and 138 completed the comprehensive cognitive assessment in 3-6 months after stroke.Logistic regression analysis showed that 3 weeks baseline cognitive status was an independent factor affecting memory (P<0.05, OR=62.47, 95%CI=13.00-205.00), execution (P<0.05, OR=38.29, 95%CI=8.00-170.00), language (P<0.05, OR=6.46, 95%CI=2.31-18.04) and information processing speed (P<0.05, OR=5.88, 95%CI=2.24-15.41) in 3-6 months after stroke.According to the number of impaired cognitive domains, the overall cognitive function was defined.There were 61 cases of no or mild cognitive dysfunction group and 77 cases of moderate or severe cognitive impairment group.Multifactor logistic analysis showed that baseline cognitive status was independent of the overall cognitive function of 3-6 months after apoplexy adjusting for the age and education level (P<0.05, OR=25.32, 95%CI=7.52-85.39). Conclusion Short cognitive assessment in early apoplexy can predict the short-term functional status of cognitive domains such as memory, execution, language and information processing speed after stroke, and can also predict the overall cognitive level.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
