Abstract
this research addressed the question: is musical memory preserved in dementia, specifically, dementia of the Alzheimer type (AD)? Six tests involving different aspects of melody and language processing were administered to each of five groups of participants: 50 younger adults, 100 older adults, and 50 AD older adults classified into three levels of AD severity—mild, moderate and severe. No test was immune to, but not all tests were equally sensitive to, the presence of dementia. Long-term familiarity for melody was preserved across levels of AD, even at the severe stage for a few individuals. Detecting pitch distortions in melodies was possible for mild and some of the moderate AD participants. The ability to sing a melody when prompted by its lyrics was retained at the mild stage and was retained by a few individuals through the severe stages of AD. Long-term familiarity with the lyrics of familiar melodies was also found across levels of AD. In contrast, detection of grammatical distortions in the lyrics of familiar melodies and the ability to complete familiar proverbs were affected even at the mild stage of AD. We conclude that musical semantic memory may be spared through the mild and moderate stages of AD and may be preserved even in some individuals at the severe stage.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
