Validated, unified theory of Alzheimer Disease illuminates two essential research questions
Bibliographic record
Abstract
Abstract Background A 2001 unified theory of thiamine deficiency (TD) in Alzheimer Disease (AD) (1‐p.85) was validated in 2015 (2), and published in 2017 (3). Update? Method Scientific literature review on topic of thiamine and/or AD. PUBMED, elibrary.wiley.com, mspace.lib.umanitoba.ca Result 1. Thiamine supplementation can potentially correct key AD abnormalities: the cholinergic deficit (1‐p.64, 4), B‐Amyloid (1‐p. 77, 3), tau (5), neuroinflammation (4, 5,6, 7) and memory (1‐p59). 2. Limited oral thiamine supplementation trials in AD have had mixed results (1‐p49, 6). Conclusion Essential research questions: a. What causes TD in AD? (altered thiamine requirements, excretion, absorption, transport, metabolism, or diet and other factors*?) (1) b. What is the optimal treatment of TD in AD? (control for medications*, medical conditions* and dietary components affecting thiamine intake and utilization* (1‐p. 52, 1‐p.53,9). Consider advantages of intramuscular injections vs. oral treatments (8), need for other nutrients (1‐p.52), proven thiamine treatments in TD diseases. References : 1. Kennedy, A.R. (2001).

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
