Contested (the paper flags this itself) — CD38 inhibition translates from preclinical NAD+ restoration to clinical benefit.
in NAD⁺ Restoration and CD38 Inhibition
Would be settled by. A CD38 inhibitor trial reporting both tissue NAD+ and a functional endpoint.
Contested (declared conflict) — The regrading is independent of the interests of the programme performing it.
in One Hundred and Fifty Theories of Alzheimer's Disease, Graded on Evidence Not Idea
Contested (a question of definition as much as evidence) — Alzheimer's disease is the far tail of lawful brain ageing rather than a disease.
in Pavel Kalvach's Case That Alzheimer's Is Not a Disease, Graded
Would be settled by. A discontinuity — a threshold or bimodality in the population distribution — which would make it a disease in the ordinary sense rather than a tail.
Contested (evidence running the other way) — A developmental tau configuration is the origin of the pathological species.
in Prenatally Generated Immature Neurons and the Cellular Origin of Alzheimer's Disease
Contested — Presenilin 1 is required for v-ATPase V0a1 maturation and lysosomal acidification
in Ralph Nixon's Endosomal–Autophagic–Lysosomal Framework of Alzheimer's Disease, Graded

in The Bredesen Protocol Compared Against the Convergent Collapse Framework
Would be settled by. A randomised controlled trial of the protocol as delivered, with a prespecified cognitive endpoint.
Contested (the paper builds on this) — The directional conflict at cofilin serine 3 in Alzheimer's disease is unresolved in the primary literature.
Would be settled by. A human measurement that states and resolves the direction of cofilin serine-3 phosphorylation in affected neurons.
Contested (the paper flags this itself) — Mitochondrial failure is genuinely upstream of proteinopathy rather than bidirectionally coupled with it.
in The Mitochondrion as Nexus (PhD Thesis)
Would be settled by. An intervention that corrects the mitochondrial lesion alone, in a model where proteinopathy is already established, and either does or does not arrest it.
Contested (the linkage itself) — TOMM40 carries risk independently of APOE.
in The Narrow Gate Every Mitochondrial Protein Must Pass
Would be settled by. Populations with recombination breaking the APOE-TOMM40 haplotype, or functional work showing a TOMM40 variant altering channel function with a phenotype.
Contested (co-occurrence under a pharmacological treatment) — Disruption of the perineuronal net causes mature neurons to revert to an immature molecular phenotype.
in The Perineuronal Matrix and Cortical Layer Two: Why Net Failure Is the Wrong Account
Would be settled by. Section 11.4, with birth-dating to exclude the reservoir as the source.
Contested (the field itself) — The modest effect sizes reflect wrong timing rather than a wrong target.
Contested — Aggregated amyloid-β is a direct neurotoxin in vivo
in Todd Golde's Amyloid Cascade, Read for What It Adds: The Organ-Failure Reframe
Would be settled by. A reproducible in vivo demonstration at physiological exposure
Moderate (inference, the paper's own claim) — Neuronal death in this disease runs on a spectrum between an intrinsic pole — quality-control failure — and an extrinsic pole — assault after loss of protection — rather than by one mode.
in A Cell-Type-Resolved Map of Death Modalities Across the Progression of Alzheimer's
Would be settled by. Assigning individual dying neurons in human tissue to positions on the spectrum, rather than inferring the spectrum from the two poles.
Moderate (inference, the paper's own claim) — Diverse upstream insults — familial mutations, viral infection, environmental toxins — are mechanistically unified by converging on the autophagy-lysosomal system.
in A Funnel Model from Upstream Etiologies to PANTHOS in Alzheimer's Disease
Would be settled by. Blocking the bottleneck downstream of two unrelated upstream insults and showing both are arrested to the same degree.
Moderate (inference, the paper's own claim) — A temporal, cellular and ecological architecture explains those three features together, where single-molecule cascades explain them separately or not at all.
in A Graded Synthesis of the Temporal, Cellular and Ecological Mechanisms of Alzheimer's
Moderate (inference) — Amyloid occupies a bounded place in the architecture rather than a primary one, with the boundary conditions stated.
in A Graded Synthesis of the Temporal, Cellular and Ecological Mechanisms of Alzheimer's
Moderate (inference, the paper's own claim) — The attack and failure models are not rivals but sequential states of one trajectory, so the apparent incompatibility dissolves once time is added.
in A Unified Synthesis of Microglial Contributions to Alzheimer's Disease
Would be settled by. Longitudinal or pseudotemporal single-cell trajectories in human tissue showing the attacking state as a precursor of the exhausted one rather than a parallel lineage.
Would be refuted by. Attacking and exhausted populations shown to arise from separate precursors, which would make them genuinely different cells rather than different moments.
Moderate (inference, the paper's own claim) — The trilogy's treatment of the neuronal substrate as a fixed population is an oversimplification that the adult-born neuron corrects.
in Adult Hippocampal Neurogenesis and the Substrate of Cognitive Reserve
Moderate (inference, the corpus's own frame) — These states are post-homeostatic trajectories from a Butovsky-defined baseline rather than independent populations.
in Aleksandra Deczkowska's DAM Program and the Matrix-Degrading Arm: MMP-2/9 and PNN Erosion
Would be settled by. Lineage tracing or live longitudinal imaging showing the transition occurring in individual cells.
Moderate (inference, the programme's own claim) — The disease is best read as a stereotyped process in time — a fifty-year front crossing the brain — rather than as a contest between primary molecules.
in Alzheimer's Disease — A Process in Time
Would be settled by. A longitudinal cohort staged across brainstem, hippocampal and cortical markers showing the stated order in the same individuals.
Moderate (inference, the entry's own claim) — Applying that instinct one level down — reading a chemical state as a process with a history rather than a static fact — is the right move for the synapse.
in Alzheimer's Disease as a Failure of Proteolytic Timing, Read Out at Cofilin Serine 3
Moderate (inference, the corpus's own claim) — That afferent traffic couples the peripheral immunometabolic state to the earliest phase of the disease.
in Anatomy of a Neurodegenerative Conduit — The Vagal Interface
Would be settled by. Vagal manipulation in a model with a brainstem-specific readout rather than a general inflammatory one.
Moderate (inference, the programme's own claim) — Memory formation runs as a two-stage process — candidate generation, then selection — and the gate between the stages is that membrane domain.
in Ari Rappoport's Lipid-Raft Theory of Plasticity, Revisited: The Symmetry Problem
Would be settled by. Manipulating domain assembly and showing candidate generation and selection dissociate as the two-stage account requires.
Moderate (inference, the paper's own claim) — Astrocytes are the hidden drivers of clearance — a principal determinant rather than a supporting one.
in Astrocytes: The Hidden Drivers of Brain Waste Clearance
Would be settled by. Selective impairment of astrocytic clearance with neuronal and microglial capacity intact, and measurement of the resulting burden.
Moderate (inference, the paper's own claim) — Astrocytes are the hidden drivers of clearance — a principal determinant rather than a supporting one.
in ASTROCYTES: THE HIDDEN DRIVERS OF BRAIN WASTE CLEARANCE
Would be settled by. Selective impairment of astrocytic clearance with neuronal and microglial capacity intact, and measurement of the resulting burden.
Moderate (inference, the paper's own claim) — Where the genes that cause a disease encode parts of the clearance apparatus — the endosomal arm of Alzheimer's via APP, PSEN1 and SORL1; progranulin-deficient frontotemporal dementia; GBA1-associated Parkinson's — clearance failure is causal and early.
in Autophagic Failure as the Convergent Endpoint in Alzheimer's, Parkinson's, ALS and Huntington's
Would be settled by. A clearance lesion introduced into different vulnerable populations, reproducing each disease's phenotype in turn.
Moderate (inference, the paper's own claim) — The decline of autophagic flux with age is a causative driver of senescence rather than a passive correlate of it.
in Autophagy as the Driver of System-Wide Aging
Would be settled by. Restoring flux alone in an otherwise ageing system and showing the senescent phenotype is delayed rather than merely accompanied.
Moderate (inference, the paper's own claim) — Those two facts together indicate the extracellular deposit is not the driver, and a timeline of plaque formation must start inside the cell.
in Autophagy Failure Mechanisms in Neurodegeneration, and the Timeline of Plaque Formation
Would be settled by. Anti-amyloid therapy given presymptomatically with a cognitive endpoint, which separates wrong-target from wrong-time.
Moderate (inference, the paper's own claim) — Decline is threshold-like rather than gradual — a system that compensates until it cannot, then fails quickly.
in Autophagy-Lysosomal Choke Points and Bistable Decline in Neurodegeneration
Would be settled by. Longitudinal measurement of clearance capacity alongside function in the same subjects, testing for a knee in the curve rather than a slope.
Would be refuted by. Clearance capacity and function found to decline proportionally, which would make the process gradual after all.
Moderate (inference, the paper's own claim) — Withdrawal of that subsidy is a cause of synapse loss rather than a consequence of having fewer synapses to support.
in BDNF and the Trophic Failure of the Synapse in Alzheimer's Disease
Would be settled by. Restoring BDNF signalling alone in a model with established pathology and measuring whether synapse loss halts.
Moderate (inference, the corpus's own frame) — Complement pruning is the principal destructive output of post-homeostatic microglia rather than one of several.
in Beth Stevens's Complement-Pruning Program: C1q, C3, CR3 and the SORL1–Lysosomal Axis
Would be settled by. Blocking each output arm separately in the same model and comparing the synaptic loss prevented.
Moderate (inference, the paper's own claim) — That diagnostic blind spot causes systematic misattribution between vascular and degenerative dementia.
in Biomarkers of Vascular Dementia and Their Overlap with Alzheimer's Disease
Would be settled by. Autopsy-confirmed comparison of clinical diagnosis against pathology in a consecutive series, quantifying the misattribution rather than inferring it.
Moderate (inference) — Disrupting the amyloid-ABAD interaction is a therapeutically meaningful intervention rather than only a useful experimental manipulation.
in Blocking the Aβ–ABAD Complex — A Pharmacology
Would be settled by. A brain-penetrant analogue with acceptable selectivity tested against a disease endpoint.
Moderate (inference) — The reelin variant is the cause of that protection rather than a coincident finding.
in Can a Drug Copy the Luckiest Mutation?
Would be settled by. A second independent carrier of the same variant with a comparable delay, or a model reproducing the protection.
Moderate (inference, the paper's own claim) — The effect runs through two mechanisms at once — removal of a specific neurotropic pathogen, and non-specific trained immunity with epigenetic reprogramming of myeloid cells.
in Can Vaccines Protect Against Dementia?
Would be settled by. Comparing dementia incidence after a vaccine that induces trained immunity without targeting a neurotropic virus, against one that does both.
Moderate (inference, the paper's own claim) — The effect runs through two mechanisms at once — removal of a specific neurotropic pathogen, and non-specific trained immunity with epigenetic reprogramming of myeloid cells.
in CAN VACCINES PROTECT AGAINST DEMENTIA?
Would be settled by. Comparing dementia incidence after a vaccine that induces trained immunity without targeting a neurotropic virus, against one that does both.
Moderate (inference) — Synapse elimination in this disease has a neuron-intrinsic arm requiring no microglion.
in Carla Shatz's Synaptic Restraint System and the C4d–LilrB2 Result
Moderate (inference) — The theory's spatial topography claim — that pathology should radiate from the sites where immature neurons are found — is testable against existing staging data.
in Carlo Abbate's Adult Neurogenesis Theory of Alzheimer's Disease, Critically Evaluated
Moderate (inference, the corpus's own claim) — These components form a single coherent cascade in the stated order.
in Cell Death Modalities in Alzheimer's Disease and Their Convergence at the Perineuronal Net
Moderate (inference, the paper's own claim) — The therapeutic inference that ceramide should therefore be lowered is wrong, because ceramide is load-bearing as well as damaging.
in Ceramide as a Structural and Signalling Node in Alzheimer's Disease
Would be settled by. A dose-ranging intervention showing a therapeutic window with harm at the low end, rather than monotonic benefit.
Would be refuted by. Monotonic benefit from ceramide reduction across the achievable range, which would vindicate the simple inference.
Moderate (inference, the paper's own claim) — The failures reflect the wrong half of the molecule being delivered rather than choline being irrelevant.
in Choline, Phosphatidylcholine and APOE4 in Alzheimer's Disease: A Saturation Asymmetry
Would be settled by. A trial delivering the species the account specifies, with a target-engagement readout showing it reached brain.
Would be refuted by. That trial failing with engagement demonstrated, which would indict choline itself rather than its delivery.
Moderate (inference, the programme's own claim) — The cysteine difference matters through lipid peroxidation chemistry — a bond that ApoE4 cannot make.
in Christopher Ramsden's ApoE-Peroxidation and ApoER2 Theory, Revisited
Would be settled by. A human measurement tying peroxidation adduct burden to genotype and to outcome in the same subjects.
Moderate (inference) — The contested residue is nonetheless the right place to look — the conflict is substantive rather than technical.
in Cofilin Serine 3 in Alzheimer's Disease: Four Laboratories, Two Opposite Signs
Moderate (inference, the paper's own claim) — A specific tyrosine phosphorylation licenses the switch between those activities, and its dysregulation is where the disease acts on the spine.
in Cofilin Serine 3: Two Opposed Transducers Activated and Condemned by One Phosphorylation
Would be settled by. Blocking the phosphorylation alone and showing spine loss is prevented under an otherwise disease-competent insult.
Moderate (inference, the paper's own claim) — The census — which cells and how many, cell type by cell type and synapse class by synapse class — resolves the disease in cellular space as its companion resolves it in time.
in Collapse, Traced Cell Type by Cell Type
Would be settled by. A single cohort counted across all the populations in the census with one method, testing whether the relative ordering survives.
Moderate (inference, the paper's own claim) — The competing viral hypotheses can be compared on a common mechanistic footing rather than treated as rival camps.
Moderate (inference, the paper's own claim) — The competing viral hypotheses can be compared on a common mechanistic footing rather than treated as rival camps.
Moderate (inference, the corpus's own claim) — The four substrates are co-extensive and held by a TGF-beta/SMAD loop gated by an APOE/LRP1 lipid-availability axis, so resilience lies in their joint preservation.
in Containment, Not Clearance, as the Variable That Changes First in the Ageing Brain
Would be settled by. Preserving three substrates while ablating the fourth and testing whether resilience is lost, which the joint-preservation claim requires.
Moderate (inference, the paper's own claim) — Where the genes that cause a disease encode parts of the clearance apparatus, clearance breakdown is the common road: the endosomal arm of Alzheimer's, progranulin-deficient frontotemporal dementia, GBA1-associated Parkinson's.
in Convergent Autophagic Collapse: Fischer's 1907 Observations and Nixon's Lysosomal Model
Would be settled by. An etiology of this kind shown to produce the disease phenotype without passing through clearance failure, which would bound the convergence.
Moderate (inference, the paper's own claim) — Depression and Alzheimer's disease lie on one continuum, differing in the reversibility of the same axis failures rather than in their identity.
in Depression as Reversible Collapse
Would be settled by. Longitudinal measurement of the five axes across subjects moving from depressive to neurodegenerative phenotype, testing whether the axes are shared and the difference is in reversibility.
Would be refuted by. An axis found engaged in one condition and demonstrably absent in the other.
Moderate (inference) — Strain identity is what distinguishes the human tauopathies from one another.
in Different Tau Strains Cause Different Diseases
Would be settled by. Strain typing of human cases against clinical phenotype in a series large enough to test whether strain predicts syndrome independently of the other differences.
Moderate (inference) — Strain identity is what distinguishes the human tauopathies from one another.
in DIFFERENT TAU STRAINS CAUSE DIFFERENT DISEASES
Would be settled by. Strain typing of human cases against clinical phenotype in a series large enough to test whether strain predicts syndrome independently of the other differences.
Moderate (inference, the paper's own claim) — Disciplinary siloing, rather than absence of evidence, is why assembly took seventy years.
in Disciplinary Silos in Alzheimer's Disease Research, 1950–2020
Would be settled by. Comparison against a matched field in which components were assembled faster, holding funding concentration constant.
Moderate (inference, the paper's own claim) — The single-sentence account — extra APP, more amyloid, earlier disease — is a profound under-reading of what trisomy 21 does.
in Down Syndrome as the Disease Run in Fast-Forward
Would be settled by. Isolating APP dosage from the rest of trisomy 21 — as partial trisomies and APP-normalised models allow — and asking how much of the phenotype survives.
Moderate (judgement, not evidence) — That absence is a defect in the account rather than an appropriate division of labour between mechanism and experience.
Moderate (inference, the paper's own claim) — The epigenetic layer lies upstream of the senescent state and is what the corpus's use of the word ageing ultimately refers to.
in Epigenetic Erosion as the Reversible Information Layer of Alzheimer's Disease
Would be settled by. Manipulating the epigenetic layer alone and showing the senescent state follows rather than accompanies.
Moderate (inference, the programme's own claim) — Failure to clear that signal — leaving the platform assembled — is a mechanism of disease rather than a consequence of it.
in Estela Area-Gómez's MAM Theory: C99 as a Cholesterol Signal That Is Never Cleared
Would be settled by. Restoring signal clearance alone in a disease model and showing the downstream phenotype resolves.
Moderate (inference) — The corpus's own model is weaker than it has admitted in three places, including that its perineuronal-net arm is largely animal and post-mortem.
in Excitatory–Inhibitory Balance in Alzheimer's: Insufficiency Against Terminal Disinhibition
Moderate (inference, the paper's own claim) — Therapeutics should be matched to disease phase, because an intervention correct for one phase can be inert or harmful in another.
in Existing and Candidate Interventions Mapped onto the Convergent Collapse Framework
Moderate (inference, the paper's own claim) — Therapeutics should be matched to disease phase, because an intervention correct for one phase can be inert or harmful in another.
in Existing and Candidate Interventions Mapped onto the Convergent Collapse Framework
Moderate (inference, the corpus's own claim) — Matrix integrity constitutes a seventh convergence axis, distinct from the six the earlier framework named.
Moderate (inference) — Fischer's marginalisation was substantially a product of institutional power and circumstance rather than of the quality of his work.
in Fischer's Sidelining: A Biographical–Intellectual History
Moderate (inference, the corpus's own reading) — Entrainment works, where it works, by restoring interneuron function and the metabolic support of the circuit rather than by clearing amyloid directly.
in Forty-Hertz Sensory Entrainment as a Candidate Disease-Modifying Therapy in Alzheimer's
Moderate (inference, the paper's own claim) — The opposite effects are explained by when the drug is given — the same agent acting on a different phase of the disease.
in From Gut Ecology to the Failed Antidepressant Trial: One Continuous Mechanism
Would be settled by. An SSRI trial stratified by disease stage with both amyloid-kinetic and cognitive endpoints.
Would be refuted by. Cognitive worsening found in presymptomatic subjects too, which would make the effect stage-independent and the prescription unsafe rather than mistimed.
Moderate (inference, the paper's own claim) — Cumulative synaptic subtraction is what carries a neuron to death, rather than death arriving by a separate mechanism.
in From Synapse Loss to Neuronal Death in Alzheimer's Disease
Would be settled by. Preventing synapse removal alone and showing the neuron survives an otherwise lethal course.
Would be refuted by. Neuronal death proceeding on schedule with synapse removal blocked, which would make subtraction a parallel process rather than the route.
Moderate (inference, the paper's own claim) — Extracellular clearance failure completes the intracellular account of the companion volume — one clearance failure at two scales.
in Glymphatic Clearance Failure in Alzheimer's Disease and the Noradrenergic Switch
Moderate (inference) — The plaque is therefore a consequence of intraneuronal accumulation and neuronal death rather than an independent extracellular process.
in Gouras: Intraneuronal Aβ and the Inside-Out Paradigm
Would be settled by. Lineage or high-resolution longitudinal pathology tying individual deposits to individual dead neurons.
Moderate (inference) — The plaque is therefore a consequence of intraneuronal accumulation and neuronal death rather than an independent extracellular process.
in GOURAS: INTRANEURONAL AΒ AND THE INSIDE-OUT PARADIGM
Would be settled by. Lineage or high-resolution longitudinal pathology tying individual deposits to individual dead neurons.
Moderate (inference, the paper's own claim) — Because it is the same machine, amyloid production and synaptic maintenance cannot be separated — anything that loads the machine degrades the synapse.
in Gunnar Gouras's Intraneuronal Amyloid and the Synaptic Endosome, Twenty-Eight Years On
Would be settled by. Increasing amyloid production without loading the recycling compartments, and asking whether synaptic function is spared.
Moderate (inference, the paper's own claim) — The attack and failure models are not rivals but sequential states of one trajectory, so the apparent incompatibility dissolves once time is added.
in HOMEOSTATIC MICROGLIAL COLLAPSE
Would be settled by. Longitudinal or pseudotemporal single-cell trajectories in human tissue showing the attacking state as a precursor of the exhausted one rather than a parallel lineage.
Would be refuted by. Attacking and exhausted populations shown to arise from separate precursors, which would make them genuinely different cells rather than different moments.
Moderate (inference, the paper's own claim) — Fischer's 1907 observations anticipate modern findings that the field arrived at independently a century later.

in HOW FREE RADICALS DISABLE THE RECYCLING SYSTEM
Would be settled by. Measurement of pump adduction against lysosomal pH in sporadic human tissue, with familial cases as the comparison.
Moderate (inference, the paper's own claim) — Those two facts together indicate the extracellular deposit is not the driver, and a timeline of plaque formation must start inside the cell.
in HOW PLAQUES ACTUALLY FORM: A TIMELINE
Would be settled by. Anti-amyloid therapy given presymptomatically with a cognitive endpoint, which separates wrong-target from wrong-time.
Moderate (inference, the programme's own claim) — The same receptor that clears pathology also carries it — LRP1 mediates uptake and spread of tau, turning a clearance route into a highway.
in HOW THE BRAIN'S CLEARANCE SYSTEM BECOMES THE DISEASE'S HIGHWAY
Would be settled by. Selective LRP1 blockade in a spreading model, measuring propagation rather than uptake.
Moderate (inference, the paper's own claim) — The vagus-to-coeruleus connection is a multi-synaptic relay with specifiable anatomy rather than the single arrow the companion volumes drew.
in How the Gut Nerve Reaches the Brainstem
Would be settled by. Tract-specific manipulation at each relay in turn, measuring coerulean response.
Moderate (inference, the paper's own claim) — A therapeutic convergence approach — addressing the shared autophagic collapse across dementia subtypes at once — would shift treatment paradigms.
Moderate (inference) — That persistence contributes causally to chronic neurodegenerative conditions rather than being an incidental accompaniment.
in HOW VIRUSES ENTER AND HIDE IN THE BRAIN
Would be settled by. Antiviral intervention against a specific organism with a neurodegenerative endpoint.
Moderate (inference, the paper's own claim) — That subversion is a plausible etiological trigger for chronic proteinopathy, not only for acute encephalitis.
in HOW VIRUSES SABOTAGE BRAIN CLEANUP
Would be settled by. Longitudinal cohorts with documented CNS infection and later proteinopathy incidence, with the autophagy readout measured in between.
Moderate (inference) — The anatomical route of spread in human Parkinson's disease follows connectivity as the model predicts.
in HOW Α-SYNUCLEIN SPREADS THROUGH THE BRAIN
Would be settled by. Longitudinal human imaging of spread along tracts, rather than inference from cross-sectional staging.
Moderate (inference, the paper's own claim) — That subversion is a plausible etiological trigger for chronic proteinopathy, not only for acute encephalitis.
in HSV-1 Suppression of Neuronal Autophagy as a Viral Route into Alzheimer's Disease
Would be settled by. Longitudinal cohorts with documented CNS infection and later proteinopathy incidence, with the autophagy readout measured in between.
Moderate (inference) — Those failures are explained by amyloid's physiological role — removing it removes something the brain needs as well as something it does not.
in HUANG: AΒ AS A TWO-FACED MOLECULE
Would be settled by. A trial in which amyloid is reduced to a defined intermediate rather than a minimum, testing for a U-shaped rather than monotonic response.
Moderate (inference, the paper's own claim) — The ER-mitochondria contact site is the real driver — upstream of amyloid rather than downstream of it.
in IS THE ER–MITOCHONDRIA CONTACT SITE THE REAL DRIVER?
Would be settled by. Contact-site correction alone preventing amyloid pathology downstream, in a system where the reverse manipulation does not prevent contact-site abnormality.
Moderate (inference, the paper's own claim) — The calcium hypothesis and the acidification account are the same account seen from two sides — calcium dysregulation and acidification failure are mechanistically coupled.
in Khachaturian: Calcium × Autolysosomal Acidification
Would be settled by. Correcting acidification alone and measuring whether calcium handling normalises, or the reverse.
Moderate (inference, the paper's own claim) — The calcium hypothesis and the acidification account are the same account seen from two sides — calcium dysregulation and acidification failure are mechanistically coupled.
in KHACHATURIAN: CALCIUM × AUTOLYSOSOMAL ACIDIFICATION
Would be settled by. Correcting acidification alone and measuring whether calcium handling normalises, or the reverse.
Moderate (inference) — Calcium dysregulation is a systems failure that sits upstream of the proteinopathies rather than beside them.
in KHACHATURIAN: THE CALCIUM HYPOTHESIS & SYSTEMS FAILURE
Would be settled by. Correcting calcium handling alone in a model and showing proteinopathy is prevented rather than merely reduced.
Moderate (inference, the programme's own claim) — Lipid peroxidation, not amyloid, is the primary driver — with amyloid and tau appearing downstream of ApoER2 crosslinking and signalling failure.
in Lipid Peroxidation and ApoER2–Dab1 Disruption in Sporadic Alzheimer's Disease
Would be settled by. An intervention that blocks peroxidation-driven crosslinking specifically, showing amyloid and tau pathology are prevented downstream.
Moderate (inference) — Amyloid deposition in human disease is, at least in part, an antimicrobial response rather than a purely pathological accumulation.
in LL-37, Innate Immunity and Autophagic Collapse in Alzheimer's Disease
Would be settled by. Demonstration that deposition in human brain tracks microbial burden rather than the other risk structure of the disease.
Moderate (inference, the programme's own claim) — The same receptor that clears pathology also carries it — LRP1 mediates uptake and spread of tau, turning a clearance route into a highway.
in LRP1 and the Templated Spread of Misfolded Protein: Guojun Bu's Discovery
Would be settled by. Selective LRP1 blockade in a spreading model, measuring propagation rather than uptake.

Would be settled by. Measuring assembly state and chaperone availability in affected human neurons alongside lysosomal pH.

in MANY CAUSES, ONE BOTTLENECK
Would be settled by. Blocking the bottleneck downstream of two unrelated upstream insults and showing both are arrested to the same degree.
Moderate (inference) — Fischer's terms map onto modern molecular categories closely enough for the mapping to be informative rather than merely suggestive.
Moderate (inference) — Fischer's terms map onto modern molecular categories closely enough for the mapping to be informative rather than merely suggestive.
in Mapping Fischer's 1907 Histopathological Terms onto Modern Autophagy Science
Moderate (inference, the paper's own claim) — A vascular Phase 0 precedes bioenergetic ignition, so the Phase I-III architecture is incomplete without it.
in Mapping the Vascular onto the Genetic Dimension (PhD)
Would be settled by. A cohort with both vascular integrity measures and brainstem tau imaging, showing which becomes abnormal first in the same individuals.
Would be refuted by. Vascular measures found normal in subjects already carrying locus-coeruleus pathology, which would place the vascular layer downstream rather than prior.
Moderate (inference) — The Phase 0 genome is largely orthogonal to the Phase I-III genome, converging on it through three integrative nodes — APOE, TREM2 and the matrix.
Moderate (inference, the programme's own claim) — Synapses are dismantled from within by a regulated proteostatic programme rather than destroyed from without.
in Margolis: How Synapses Are Dismantled from Within

Would be settled by. Removing the proposed restraint in an otherwise resilient brain or model and showing the cognitive phenotype appears.
Moderate (inference, the programme's own claim) — MAM dysfunction is upstream in Alzheimer's disease rather than a consequence of it.
in Mitochondria-Associated ER Membranes and Ceramide in Alzheimer's Disease
Would be settled by. Selective disruption of the tether in an otherwise healthy system, and whether the disease phenotype follows.
Moderate (inference, the paper's own claim) — Mitochondrial and autophagy-lysosomal quality control is the machinery that the earlier theses invoked loosely as 'metabolic fitness'.
in Mitochondrial, Autophagy-Lysosomal and Metabolic Quality Control in Alzheimer's Disease
Would be settled by. Manipulating quality-control capacity alone and showing the metabolic-fitness phenotype follows.
Moderate (inference, the programme's own claim) — Chronic excitatory insufficiency is the root cause — the network is tipped toward inhibition and amyloid and tau are compensatory sensitisers rather than toxins.
in Moosmann & Sohre: NMDA Failure as the Root Cause
Would be settled by. Direct measurement of net excitatory-inhibitory balance in early human disease, rather than inference from downstream phenomena.
Moderate (inference, the programme's own claim) — Chronic excitatory insufficiency is the root cause — the network is tipped toward inhibition and amyloid and tau are compensatory sensitisers rather than toxins.
in MOOSMANN & SOHRE: NMDA FAILURE AS THE ROOT CAUSE

in Neurotropic Viral Invasion of the Central Nervous System
Would be settled by. Antiviral intervention against a specific organism with a neurodegenerative endpoint.
Moderate (inference, the paper's own claim) — The nine accounts are descriptions of one failure seen from nine positions, not nine competing mechanisms.
in Nine Accounts of the Failing Synapse, and the One Lesion They Describe
Would be settled by. An intervention against one programme's mechanism producing the phenotype another programme predicts, which would show the mechanisms are coupled rather than parallel.
Would be refuted by. Two of the nine mechanisms shown to be independently sufficient for synapse loss in the same preparation, which would make them alternatives rather than aspects.
Moderate (inference, the paper's own claim) — Ketamine's effects present a paradox for the corpus's account — an NMDA antagonist helping where the account predicts excitatory insufficiency should be worsened.
in NMDA Receptor Blockade, Perineuronal Net Dynamics and Cell Death Modalities in Alzheimer's
Would be settled by. Cell-type-resolved measurement of ketamine's effect on parvalbumin versus pyramidal populations in an Alzheimer model.
Moderate — chronic norepinephrine excess over-activates glycogen-synthase-kinase-3β and drives tau, constituting the second arm
Moderate — matrix metalloproteinase-9 degrades the lectican perineuronal net in the brain
Moderate — to-plausible — norepinephrine induces matrix metalloproteinase-9 in the brain through β-adrenergic receptors on microglia and astrocytes (the first arm's receptor joint)
Moderate — the noradrenergic output rises, not falls, during the pathogenic window (the excess the pincer requires)

in The Innate-Immune Sensor That Converts the Disease
Would be settled by. Inflammasome ablation in a model with established proteinopathy, showing the phenotype is arrested rather than merely dampened.
Would be refuted by. Ablation leaving the disease course substantially unchanged, which would return the inflammasome to the status of amplifier.

Would be settled by. A longitudinal cohort staged on all three substrates, entering them in the stated order.
Moderate (inference, the paper's own claim) — Vascular pathology phases with the parenchymal sequence rather than accumulating independently alongside it.
in The Vascular Phasing (PhD Thesis)
Would be settled by. Vascular and parenchymal markers measured together longitudinally, testing for coupling rather than co-occurrence.
Moderate (inference, the paper's own claim) — Apathy and weight loss in the prodrome are consequences of mesolimbic dopamine loss — the price of effort rising.
in The Ventral Tegmental Area in Alzheimer's Disease: Vulnerability, Trajectory, Disinhibition
Would be settled by. Dopaminergic imaging of the VTA against prodromal apathy measures in the same subjects.
Moderate (inference, the entry's own claim) — The shared structure indicates a systematic error — subtraction of an excess that is compensatory rather than causal.
in Three Subtractive Alzheimer's Trials That Engaged Their Target and Left Patients Worse
Would be settled by. A fourth subtraction trial, prospectively predicted by the account to fail, doing so with target engagement demonstrated.
Would be refuted by. A subtraction trial succeeding, which the account holds should not happen for a compensatory excess.
Moderate (inference, the paper's own claim) — The partition of tryptophan between branches is a shared metabolic node at which several axes of the disease meet.
in Tryptophan Allocation Across the Kynurenine, NAD⁺ and Serotonergic Branches
Would be settled by. Shifting the partition experimentally and measuring the downstream axes together, testing whether they move in concert.
Moderate (inference, the paper's own claim) — The consistency across different vaccines points to a shared non-specific mechanism — trained immunity — rather than to any one pathogen.
Moderate (inference, the paper's own claim) — The consistency across different vaccines points to a shared non-specific mechanism — trained immunity — rather than to any one pathogen.
Moderate (inference, the paper's own claim) — The trilogy's parenchymal account is incomplete without the vascular dimension, which contributes actively rather than consequentially.
in Vascular Pathology as a Substrate Across Phases
Would be settled by. Vascular and parenchymal measures taken together longitudinally, establishing which moves first in the same subjects.
Moderate — the reset is implemented by the alternation the somatostatin cell schedules
in Wandering in Alzheimer's Disease: A Search Program on a Map That Cannot Be Reset
Moderate — the deficit in getting lost is in the reset rather than the metric
in Wandering in Alzheimer's Disease: A Search Program on a Map That Cannot Be Reset
Moderate — cholinergic denervation degrades both the metric and the switch
in Wandering in Alzheimer's Disease: A Search Program on a Map That Cannot Be Reset
Moderate — sundowning reflects circadian phase delay
in Wandering in Alzheimer's Disease: A Search Program on a Map That Cannot Be Reset
Moderate (inference, the paper's own claim) — Failure of oligodendrocyte maintenance is an upstream contributor rather than a consequence of neuronal loss.
in WHEN MYELIN'S CARETAKERS FAIL
Would be settled by. Selective disruption of oligodendrocyte maintenance in an otherwise intact system, and whether neuronal loss follows.
Moderate (inference, the paper's own claim) — That diagnostic blind spot causes systematic misattribution between vascular and degenerative dementia.
in WHEN POOR BLOOD FLOW CAUSES DEMENTIA
Would be settled by. Autopsy-confirmed comparison of clinical diagnosis against pathology in a consecutive series, quantifying the misattribution rather than inferring it.
Moderate (inference) — Microglial autophagic failure is what turns a protective immune cell into a damaging one.
in WHEN THE BRAIN'S IMMUNE CELLS TURN TOXIC
Would be settled by. Restoring autophagic capacity in microglia alone and showing the damaging phenotype reverses.
Moderate (inference, the programme's own claim) — The microbial ecosystem is the most upstream and most modifiable variable in the chain ending at the disease.
in When the Gut Writes the First Depression
Would be settled by. A microbiome intervention with a downstream neurodegenerative endpoint, rather than a composition-outcome association.
Moderate (inference, the paper's own claim) — The major neurodegenerative diseases are therefore one disease, differing in which protein templates and which cells are vulnerable.
in WHY ALL MAJOR NEURODEGENERATIVE DISEASES ARE THE SAME DISEASE
Would be settled by. A shared intervention against templating that alters the course of more than one of these diseases.
Moderate (inference, the programme's own claim) — The neuron dies from the inside out — internal proteostatic failure — rather than from external assault by aggregates.
in WHY DAMAGED MITOCHONDRIA CAN'T BE CLEARED
Would be settled by. Preventing intraneuronal accumulation while leaving extracellular deposition intact, and asking whether the neuron survives.
Moderate (inference, the paper's own claim) — Decline is threshold-like rather than gradual — a system that compensates until it cannot, then fails quickly.
in WHY DECLINE HAPPENS SUDDENLY, NOT GRADUALLY
Would be settled by. Longitudinal measurement of clearance capacity alongside function in the same subjects, testing for a knee in the curve rather than a slope.
Would be refuted by. Clearance capacity and function found to decline proportionally, which would make the process gradual after all.
Moderate — physical activity attenuates the coupling of amyloid burden to cognitive decline in the preclinical brain
Moderate — a multidomain lifestyle intervention including exercise slows cognitive decline in at-risk, non-demented elders
Moderate (inference, the paper's own claim) — The HMS model as currently drawn is incomplete and requires a fourth layer.
Would be settled by. A case in which the three-layer model makes a wrong prediction that the four-layer model makes correctly.
Moderate (inference, the paper's own claim) — Structural, assembly and chaperone defects of the V-ATPase are a principal route by which neuronal clearance fails in disease.
in WHY THE CELL'S RECYCLING SYSTEM BREAKS
Would be settled by. Measuring assembly state and chaperone availability in affected human neurons alongside lysosomal pH.
Moderate (inference) — Those failures are explained by amyloid's physiological role — removing it removes something the brain needs as well as something it does not.
in Zhen Huang's Competitive Synaptic Plasticity and the Amyloid-β Monomer Depletion Model
Would be settled by. A trial in which amyloid is reduced to a defined intermediate rather than a minimum, testing for a U-shaped rather than monotonic response.
Moderate (inference) — The anatomical route of spread in human Parkinson's disease follows connectivity as the model predicts.
in α-Synuclein Templating and Synucleinopathy Propagation: Lee and Trojanowski Evaluated
Would be settled by. Longitudinal human imaging of spread along tracts, rather than inference from cross-sectional staging.
