Convergent Verdict — 80% Confidence
Amyloid-beta is correlative in sporadic Alzheimer's, not the primary causal agent. Tau pathology, neuroinflammation, and metabolic dysfunction are the primary drivers of neurodegeneration.
All 8 worldviews agree: amyloid can initiate in familial cases (APP/PSEN mutations, Down syndrome) but the cascade becomes independent. Sporadic AD — 95% of cases — is driven by tau, inflammation, and metabolic factors. $40B and 30 years were spent optimizing the wrong target.

The Genetics Problem
APP/PSEN mutations prove amyloid CAN initiate — but the cascade becomes independent
Familial AD (APP, PSEN1, PSEN2 mutations, Down syndrome trisomy 21) accounts for <5% of cases. All converge on amyloid overproduction. But sporadic AD — 95% of cases — does not. GWAS hits point to microglial function and lipid metabolism. Clearing amyloid after tau becomes self-sustaining is extinguishing the match after the house is on fire.
Field Failure — Why the Hypothesis Survived 30 Years
Paradigm Lock
Funding capture + publication bias + career incentives = 30 years of misallocation
~70% of NIH AD funding went to amyloid research. Pharmaceutical companies invested $40B+ in amyloid-targeting drugs. Journals favored positive amyloid results; negative results went unpublished. Early-career researchers who proposed alternatives faced professional marginalization. When a hypothesis becomes an institution, the self-correcting nature of science fails.

What Was Not Pursued
Tau-targeting therapies lagged decades behind despite Braak staging evidence. TREM2/microglial therapeutics remain early-stage despite being top GWAS hits. Brain insulin resistance ("Type 3 diabetes") was proposed 15+ years ago but metabolic AD trials are scarce. Vascular health, blood-brain barrier integrity, and the glymphatic system were overshadowed.
The Lesne Scandal
Data Integrity Crisis
Lesne 2006: Ab*56 paper cited 2,300+ times, flagged for image manipulation in 2022
This Nature paper became foundational to the oligomeric amyloid hypothesis and influenced billions in drug development targeting oligomeric amyloid. The broader publication bias cycle (only amyloid-positive results got published and funded) created a self-reinforcing evidence distortion that extended far beyond a single paper.
Research Priorities
Tau Pathology
Tau misfolding inhibitors, trans-synaptic spread prevention, tau-specific PET tracers for early diagnosis.
Neuroinflammation / TREM2
Microglial modulation, TREM2 therapeutics, disease-associated microglia targeting.
Metabolic Dysfunction
Brain insulin resistance, glucose metabolism, vascular health, glymphatic clearance.
Combination Therapies
Multi-target trials: amyloid (early) + tau + anti-inflammatory + metabolic support.
Methodology: Two-phase adversarial AI synthesis. Phase 1: Convergence Engine — 100,000 perspectives across 8 worldviews (neuroinflammation, tau biology, synaptic biology, metabolic neurology, infectious hypothesis, genetics, clinical trials, neuropathology) through 4 lenses (amyloid verdict, primary mechanism, field failure, overlooked angles). 125 batches per worldview. Phase 2: The Crucible — 4 attack (amyloid causality) vs 6 defense (amyloid as biomarker) worldviews across 3 escalating rounds (core mechanism, Lesne scandal, clinical reality). Defense won at 75% confidence. Total runtime: 47.1 minutes, 600 API calls. This is scientific synthesis, not original laboratory research. All findings should be validated against primary literature.
The amyloid hypothesis survived 30 years not because the science supported it, but because the institutions did.
