1223 – Executive Functions, Visuoconstructive Ability And Memory In Institutionalized Elderly
Bibliographic record
Abstract
Introduction Executive functions (EF) are associated to frontal lobes and cognitive decline (CD) with worse results on EF tests. Objectives/aims Analyze if the Frontal Assessment Battery/FAB assessing EF discriminates elders with CD (vs. with no CD; Montreal Cognitive Assessment/MoCA), and if the results obtained with the Rey Osterreith Complex Figure Test/ROCF (copy's quality, immediate, and delayed memory) are associated with the CD presence/absence. Moreover, we wanted to assess if copy's quality and 3 minutes memory test are associated with FAB results, since these two tests are supposedly associated with EF and with frontal lobes assessed by the FAB, contrarily to the 20 minutes memory (supposedly related to the temporal area). Methodology 556 institutionalized elders (age: M ± SD =80.2 ± 5.23; range=60-100) filled in voluntarily a sociodemographic questionnaire, ROCF, MoCA and FAB. Results FAB and all ROCF tests were associated with the absence/presence of CD. Regarding variables stratified by age and education, FAB was associated with immediate memory but not with copy's quality nor with delayed memory. With no stratified ROCF and FAB, correlations confirmed the previous associations, but also between FAB and copy's quality. Conclusions Results follow the literature regarding the association between immediate memory and EF (associated to frontal lobes), in contrast to the long-term memory which is associated with the temporal area and that was not associated with FAB. Results concerning copy's quality (ROCF) are not consensual.

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.
