what needs testing

The corpus's own open questions

Every claim these papers grade short of settled, with the experiment that would settle it. 832 graded claims across 224 papers; 426 rest on established work, 406 do not, and 239 of those name the measurement that would decide them. This is the part of the account that is still owed to the reader.

Weak (predicted, untested) — Extracellular pathology, amyloid plaques included, is downstream debris of an inside-out collapse rather than an independent process.

in A Funnel Model from Upstream Etiologies to PANTHOS in Alzheimer's Disease

Would be settled by. High-resolution human pathology showing dense-core plaques forming at sites of intraneuronal collapse rather than seeding independently.

Weak (predicted, untested) — The transition between the two states has a definable trigger and a definable window in which intervention changes the outcome.

in A Unified Synthesis of Microglial Contributions to Alzheimer's Disease

Would be settled by. Identification of a state-transition marker whose manipulation moves cells between the two states in vivo.

Weak (predicted, untested) — The final step — the mode by which the affected neuron actually dies — is as this thesis specifies.

in Cell Death Modalities in Alzheimer's Disease and Their Convergence at the Perineuronal Net

Would be settled by. Direct identification of the death programme in the affected population in human tissue, rather than inference from the model systems in which each candidate programme was characterised.

Would be refuted by. The affected neurons shown to persist in a silenced but living state, which would make the terminal step a functional disconnection rather than a death.

Weak (inference, against contrary human genetics) — The APOE effect reaches dementia through tau, with amyloid-beta downstream and initially protective.

in Christopher Ramsden's ApoE-Peroxidation and ApoER2 Theory, Revisited

Would be settled by. A discriminating measurement of whether ApoER2 occlusion or intraneuronal amyloid accounts for the entorhinal vulnerability the framework's map describes.

Weak (predicted, untested) — The ordering of cellular vulnerability maps onto the three-phase temporal architecture.

in Collapse, Traced Cell Type by Cell Type

Would be refuted by. A population found to fall in an order inconsistent with the phase to which the architecture assigns it.

Weak (human tissue, against the claim) — All roads lead to the same failure — every etiology of dementia and related neurodegeneration converges on clearance breakdown, Huntington's included.

in Convergent Autophagic Collapse: Fischer's 1907 Observations and Nixon's Lysosomal Model

Would be refuted by. Already bounded by that evidence. What survives is that clearance is overtaken late in Huntington's, as a consequence of a lesion that begins elsewhere.

Weak (predicted, untested) — The point at which the continuum becomes irreversible is identifiable, and therefore treatable before it.

in Depression as Reversible Collapse

Weak (argued, not measured) — Cascade-challenging work faced differential difficulty in publication and citation.

in Disciplinary Silos in Alzheimer's Disease Research, 1950–2020

Would be settled by. A citation and acceptance analysis of cascade-challenging against cascade-consistent submissions over the period.

Weak (predicted, untested) — The compression is architectural rather than merely accelerated — the disease in Down syndrome runs the same sequence faster, with specified alterations, rather than a different sequence.

in Down Syndrome as the Disease Run in Fast-Forward

Weak (predicted, untested) — Anti-amyloid antibodies underperform because they are administered in the wrong phase, not because the target is wrong.

in Existing and Candidate Interventions Mapped onto the Convergent Collapse Framework

Would be settled by. Re-analysis of completed anti-amyloid trials with phase-stratified biomarker panels, testing whether effect size tracks phase at enrolment.

Would be refuted by. Effect size found flat across phase strata, which would mean timing is not what separates responders from non-responders.

Weak (predicted, untested) — Anti-amyloid antibodies underperform because they are administered in the wrong phase, not because the target is wrong.

in Existing and Candidate Interventions Mapped onto the Convergent Collapse Framework

Would be settled by. Re-analysis of completed anti-amyloid trials with phase-stratified biomarker panels, testing whether effect size tracks phase at enrolment.

in HOW TO FIX THE BROKEN RECYCLING SYSTEM

Would be settled by. Prospective use of an autophagy-flux marker as a prespecified stratifier in a trial powered for the interaction.

Weak (predicted, untested) — Combination therapies acting at different points of the clearance pathway will amplify benefit rather than merely add toxicity.

in HOW TO FIX THE BROKEN RECYCLING SYSTEM

Would be refuted by. A combination arm showing no benefit over the better single agent.

Weak (inference, against contrary human genetics) — Amyloid-beta secretion is initially a protective antioxidant response to peroxidised lipid, and plaques are overwhelmed protection.

in Lipid Peroxidation and ApoER2–Dab1 Disruption in Sporadic Alzheimer's Disease

Would be settled by. Direct evidence that amyloid-beta monomer at physiological concentration neutralises lipid aldehydes in the synaptic environment, and that the intraneuronal pool behaves as the framework requires.

Weak (predicted, untested) — Extracellular pathology, amyloid plaques included, is downstream debris of an inside-out collapse rather than an independent process.

in MANY CAUSES, ONE BOTTLENECK

Would be settled by. High-resolution human pathology showing dense-core plaques forming at sites of intraneuronal collapse rather than seeding independently.

Weak (predicted, untested) — Genotype-stratified anti-amyloid therapy — stratifying by APOE and cerebral amyloid angiopathy risk — will improve the benefit-to-ARIA ratio.

in Mapping the Vascular onto the Genetic Dimension (PhD)

Would be settled by. Re-analysis of completed anti-amyloid trials with ARIA rates stratified by APOE genotype and baseline vascular burden.

Weak (predicted, untested) — Vascular biomarkers — sVCAM-1, soluble PDGFR-beta, CSF claudin-5 — will stratify outcome in Collapse-programme trial designs.

in Mapping the Vascular onto the Genetic Dimension (PhD)

Would be settled by. Prospective inclusion of the three markers as prespecified stratifiers in a trial powered to detect an interaction.

Weak (human tissue, against the claim) — The same clearance lesion underlies Huntington's — the diseases differ in which cells fail rather than in how.

in ONE MECHANISM, MANY DISEASES (AD, PD, ALS, HD)

Would be refuted by. Already refuted as stated. What survives is the weaker claim that clearance is overtaken late in Huntington's, as a consequence of the illness.

Weak (predicted, untested) — Ferroptosis inhibition is the load-bearing drug class for Phase II.

in Phase II: Ferroptosis and the Oligodendrocyte Crisis

Would be settled by. A ferroptosis inhibitor trialled at the phase the account specifies, with an oligodendrocyte-injury readout rather than a cognitive endpoint alone.

Weak (predicted, untested) — MMP-9 inhibition opens a therapeutic window in Phase III specifically.

in Phase III: MMP-9 Inhibitors and the Therapeutic Window

Would be settled by. A phase-stratified trial of MMP-9 inhibition with a matrix-integrity readout alongside the cognitive endpoint.

Weak (inference, against contrary human genetics) — Amyloid-beta secretion is initially a protective antioxidant response to peroxidised lipid, and plaques are overwhelmed protection.

in RAMSDEN: WHEN OXIDATIVE DAMAGE REACHES THE SYNAPSE

Would be settled by. Direct evidence that amyloid-beta monomer at physiological concentration neutralises lipid aldehydes in the synaptic environment, and that the intraneuronal pool behaves as the framework requires.

Weak (predicted, untested) — Biomarkers of autophagic function can stratify patients for trial entry and tailor intervention to a patient's proteostatic defect or genotype.

in Restoring Autophagy in Neurodegeneration: A Therapeutic Convergence Roadmap

Would be settled by. Prospective use of an autophagy-flux marker as a prespecified stratifier in a trial powered for the interaction.

Weak (contested by the first direct measurement) — Retromer-dependent endosomal recycling is COMMON: the same failure is the operative lesion in most sporadic Alzheimer's disease.

in Scott Small's Retromer and Endosomal Theory: What Is Established, and What Just Failed

Would be settled by. An adequately powered panel of pathway-function measures across a large, longitudinally followed cohort stratified by SORL1 genotype and amyloid status, asking in what fraction of sporadic disease pathway function is measurably impaired.

Weak (predicted, untested) — Sleep interventions will act only in the preclinical and prodromal window and not on established disease.

in Sleep as the Shared Off-Line State of Every Collapse Axis

Would be refuted by. A sleep intervention showing benefit in established Alzheimer's disease.

Weak (predicted, untested) — The two bridges between phases are mechanistically as specified rather than merely temporal adjacencies.

in The 50-Year Front — The Temporal Architecture of Alzheimer's

Would be settled by. Blocking the proposed bridge mechanism in a model and showing the next phase does not begin on schedule.

Weak (predicted, untested) — A Phase I biomarker is achievable — the earliest phase is silent to current instruments rather than absent.

in The Biomarker Cascade (PhD Thesis)

Weak (predicted, untested) — Mitophagy fails earliest and most severely in locus-coeruleus and other brainstem aminergic neurons, before cortical involvement and before plaque.

in The Clearance Collapse — One Machinery, Three Failures

Would be settled by. Stage-resolved mitophagy markers in human brainstem across Braak stages 0–II.

Would be refuted by. Mitophagy markers found intact in the locus coeruleus through the decades in which this paper places the ignition.

Weak (predicted, untested) — The acidification lesion is lipid-peroxidative — v-ATPase failure tracks 4-HNE adduction of the pump.

in The Clearance Collapse — One Machinery, Three Failures

Would be settled by. Direct measurement of lysosomal pH against v-ATPase adduction in the same neurons, with lipid-peroxidation suppression as the intervention arm.

Weak (predicted, untested) — The graded catalogue of protective genes and epigenetic states is complete enough to constitute an architecture rather than a list.

in The Genes That Protect — Phenocopy the Fortunate

Would be settled by. A protective allele predicted by the architecture and then found, which is the test any structural account of a genome should be able to pass.

Weak (predicted, untested) — A phase-weighted polygenic score will predict conversion better than a conventional flat polygenic risk score.

in The Genetic Architecture of Neurodegeneration (PhD)

Would be settled by. Head-to-head comparison of a phase-weighted against a conventional polygenic score for discrimination and calibration in an existing longitudinal cohort.

Would be refuted by. A phase-weighted score performing no better than the flat score, which would mean the temporal structure carries no information the linear model does not already hold.

Weak (predicted, untested) — The assignment of specific loci to specific phases is correct in detail, not merely in outline.

in The Genetic Architecture of Neurodegeneration (PhD)

Would be settled by. Stage-resolved single-cell expression across human brain at Braak 0-VI, testing whether each locus's effector cell is transcriptionally engaged in the phase assigned to it.

Weak (predicted, untested) — A therapy defined by the pathology it leaves alone is viable in human disease.

in The Indifferent Neuron

Weak (predicted, untested) — The framework the paper builds on that conflict is necessary — that is, the conflict has no conventional resolution.

in The Load-Bearing Neuron

Would be refuted by. A conventional resolution of the serine-3 conflict, which the paper acknowledges would make its later parts redundant.

Weak (analogy) — The bacterial competition system, in which peptides such as nisin act oppositely by assembly state, is the right structural analogy.

in The Losing Axon

Weak (predicted, untested) — Alzheimer's disease is what happens when the competition signalling system loses its balance.

in The Losing Axon

Weak (analogy) — The bacterial competition system, in which peptides such as nisin act oppositely by assembly state, is the right structural analogy.

in THE LOSING AXON

Weak (predicted, untested) — Alzheimer's disease is what happens when the competition signalling system loses its balance.

in THE LOSING AXON

Weak (human tissue, against the claim) — All roads lead to the same failure — every etiology of dementia and related neurodegeneration converges on clearance breakdown, Huntington's included.

in THE MASTER THEORY: WHY ALL ROADS LEAD TO THE SAME FAILURE

Would be refuted by. Already bounded by that evidence. What survives is that clearance is overtaken late in Huntington's, as a consequence of a lesion that begins elsewhere.

Weak (predicted, untested) — The transition between the two states has a definable trigger and a definable window in which intervention changes the outcome.

in THE MICROGLIAL THESIS (DOWNLOADABLE PDF)

Would be settled by. Identification of a state-transition marker whose manipulation moves cells between the two states in vivo.

Weak (predicted, untested) — The evidence base is deepest in Alzheimer's disease, and the account will extend to Parkinson's, ALS, Huntington's and FTD on the same terms.

in The Mitochondrion as Nexus (PhD Thesis)

Weak (predicted, untested) — Combined perineuronal-net preservation and choroid-plexus interferon tone constitute a usable compound biomarker of therapeutic effect.

in THE PERIPHERAL ARM OF HOMEOSTATIC COLLAPSE

Weak (predicted, untested) — Alzheimer's disease is better understood as an immunological failure than as an organ-specific proteinopathy.

in Vaccines That May Prevent Dementia

Weak (predicted, untested) — Alzheimer's disease is better understood as an immunological failure than as an organ-specific proteinopathy.

in VACCINES THAT MAY PREVENT DEMENTIA

Weak (predicted, untested) — The added layer is load-bearing rather than descriptive — it changes what the model predicts, not only what it describes.

in WHY HMS BECOMES HMS+P

Contested (the literature itself) — Any specific virus is causally responsible rather than incidentally associated.

in Comparing Different Viral Triggers

Would be settled by. An antiviral or vaccine intervention trial against a specific organism with dementia incidence as a prespecified endpoint.

Contested (the literature itself) — Any specific virus is causally responsible rather than incidentally associated.

in COMPARING DIFFERENT VIRAL TRIGGERS

Would be settled by. An antiviral or vaccine intervention trial against a specific organism with dementia incidence as a prespecified endpoint.

Contested (the paper flags this itself) — The negative deferiprone Phase II trial in Alzheimer's disease is interpretable as a failure of the iron hypothesis.

in Iron Chelation and GPX4 Stabilization

Would be settled by. A chelation trial with a target-engagement readout showing brain iron actually moved, which the negative trial cannot establish.

Contested (the paper flags this itself) — Nicotinamide riboside and nicotinamide mononucleotide differ meaningfully in cellular bioavailability.

in NAD⁺ Restoration and CD38 Inhibition

Would be settled by. Head-to-head human pharmacokinetics with tissue-level NAD+ measurement rather than plasma metabolite inference.

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 (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 (the evidence base itself) — The protocol's reported clinical outcomes constitute evidence of efficacy.

in TESTING A POPULAR TREATMENT PROTOCOL

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.

in The Load-Bearing Neuron

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.

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) — 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 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 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) — 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 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, 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 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.

in Comparing Different Viral Triggers

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.

in COMPARING DIFFERENT VIRAL TRIGGERS

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.

in Ecce Homo: City Air

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 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 1907 OBSERVATIONS PREDICT MODERN FINDINGS

Would be settled by. Systematic comparison of all Fischer's stated claims against modern findings, counting the failures alongside the anticipations.

Moderate (inference, the paper's own claim) — Oxidative inhibition of the proton pump phenocopies the genetic defects of familial disease, producing the autophagy failure Nixon describes.

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.

in HOW TO FIX THE BROKEN RECYCLING SYSTEM

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) — 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.

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. 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.
