Clinical study on cognitive function and event-related potential N400 in the patients with mild cognitive impairment
Bibliographic record
Abstract
Objective To explore the cognitive function and event-related potential N400 in patients with mild cognitive impairment(MCI).Methods Twenty patients with MCI(MCI group) and 23 normal controls(control group) were investigated.All subjects were assessed with mini-mental state examination(MMSE) and Montreal cognitive assessment score(MoCA) and event-related potential N400 measurement.The correlation between cognition and event-related potential N400 was analyzed and its diagnostic value for MCI was evaluated.Results The scores of MMSE and MoCA were significantly lower in MCI group than in control group(P0.05,P0.01).N400 latency was significantly longer in MCI group than in control group(P0.05,P0.01).N400 amplitude was significantly lower in MCI group than in control group(P0.05).The latency and amplitude of N400 significantly correlated to the scores of MMSE and MoCA.Conclusion The findings suggest that MCI patients have impairment in their cognitive function and N400. Event-related potential N400 is valuable in the diagnosis of MCI.

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.
