Plasmalogen Deficit: A New and Testable Hypothesis for the Etiology of Alzheimer’s Disease
Bibliographic record
Abstract
Alzheimer’s disease (AD) is a complex cognitive disorder for which the single greatest risk factor is age. The pathophysiological basis for AD is still a matter of debate with no current hypothesis explaining all of the complex pathological changes observed. These include neurofibrillary tangles, amyloid plaques, neuroinflammation, hypomyelination, neuronal shrinkage (eg. Nbasalis cholinergic neurons, resulting in a dramatic cholinergic deficit), ocular pathology, microvascular pathology and liver peroxisomal dysfunction. The hypothesis that we are presenting, namely peroxisomal dysfunction resulting in decreased supply of critical ethanolamine plasmalogens to the brain, eye and vascular endothelium, is the first hypothesis that can potentially explain all of these complex pathologies in AD. The value of this hypothesis is that it is imminently testable via resupply of critical ether lipid precursors of plasmalogens. PPI-1011 is such a drug candidate and will be presented after a review of the basis of this hypothesis.

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.
