[P‐166]: Preservation of episodic and semantic musical memory in severe Alzheimer's disease
Bibliographic record
Abstract
The neural networks activated during music perception and interpretation are morphologically and functionally different from other cognitive funtions. Particularly verbal and visuospatial episodic and semantic memory have different modular networks in relation to episodic and semantic musical memory. To compare both memory system in a professional musician, piano player with Alzheimer's disease. We compared her capacity for learning and remembering verbal and written material versus auditory and visual musical memory material during 7 consecutive days. After the 4th days she was able to learn and recall new auditory music, improving by day in rhythm, melody and performance. Her mood, using Geriatric Depression Scale, and behavioral difficulties, using NPI, also showed improvement. However she showed no learning and or memory for the verbal, written or the visual musical material. The exploration of semantic and episodic musical memory in AD and related dementias may be a way to evaluate cognitive functions when other are not possible.

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.
