Abstract

fetched live from OpenAlex

BACKGROUND/AIMS: Delusions in Alzheimer's disease (AD) may be associated with functional impairment. No studies to date have used functional instruments sensitive to changes in frontal executive function, possibly underestimating the impact. METHODS: Patients with AD with and without delusions were administered cognitive tests and questionnaires to assess depression and quality of life. Caregivers were administered questionnaires to assess functional impairment, caregiver burden and behavioural symptoms. RESULTS: AD patients with delusions (n = 19) when compared to AD patients without delusions (n = 19) matched for age, education and global cognitive function were significantly more functionally impaired based on performance on the Disability Assessment for Dementia Scale (p < 0.005). CONCLUSION: AD patients with delusions have significantly worse functional performance.

Full frame distilled prediction

Teacher imitation

Not 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.
