Abstract

Multifactorial mechanisms underlying late-onset Alzheimer’s disease (LOAD) are poorly characterized from an integrative perspective. Here spatiotemporal alterations in brain amyloid-β deposition, metabolism, vascular, functional activity at rest, structural properties, cognitive integrity and peripheral proteins levels are characterized in relation to LOAD progression. We analyse over 7,700 brain images and tens of plasma and cerebrospinal fluid biomarkers from the Alzheimer’s Disease Neuroimaging Initiative (ADNI). Through a multifactorial data-driven analysis, we obtain dynamic LOAD–abnormality indices for all biomarkers, and a tentative temporal ordering of disease progression. Imaging results suggest that intra-brain vascular dysregulation is an early pathological event during disease development. Cognitive decline is noticeable from initial LOAD stages, suggesting early memory deficit associated with the primary disease factors. High abnormality levels are also observed for specific proteins associated with the vascular system’s integrity. Although still subjected to the sensitivity of the algorithms and biomarkers employed, our results might contribute to the development of preventive therapeutic interventions.

  • Vascular alterations such as cerebrovascular resistance and hypoperfusion may precede amyloid deposition and are predictive of future disease progression.

    “In support of this hypothesis, recent evidence from neuroimaging studies suggests that vascular alterations such as cerebrovascular resistance and hypoperfusion may precede amyloid deposition and are predictive of future disease progression (Iturria-Medina et al., 2016; Yew et al., 2017).”

    From White matter diffusion alterations precede symptom onset in autosomal dominant Alzheimer’s disease (2018) · cites this paper as Iturria-Medina et al., 2016

    The Discussion (page unavailable) says the modeled vascular abnormalities appear earlier than amyloid-β deposition, and the Methods describe cerebral blood-flow imaging. But the paper does not establish cerebrovascular resistance as an early marker or show that these alterations predict an individual’s future disease progression; its Discussion describes prediction as a potential use of the model.

  • Age-related vascular changes may influence disease progression in late-onset Alzheimer's disease, including the development of white matter alterations, which is less likely to be captured in autosomal dominant Alzheimer's disease where dementia symptoms typically emerge between 30 and 50 years of age.

    “Age-related vascular changes may influence disease progression in late-onset Alzheimer’s disease, including the development of white matter alterations (Iturria-Medina et al., 2016), which is less likely to be captured in autosomal dominant Alzheimer’s disease where dementia symptoms typically emerge between 30 and 50 years of age.”

  • WMHs often occur prior to the presence of amyloid-β plaques in preclinical AD.

    “findings from previous studies have also shown that WMHs often occur prior to the presence of amyloid-β plaques in preclinical AD [19,20,21]”

    From Amyloid-PET and White Matter Hyperintensities Have Independent Effects on Baseline Cognitive Function and Synergistic Effects on Longitudinal Executive Function (2023) · cites this paper as [20]

    The Results (Multifactorial biomarker ordering in LOAD progression) place vascular dysregulation before Aβ deposition. But the Discussion says the analysis did not evaluate white-matter alterations, so it does not establish that WMHs specifically precede amyloid plaques in preclinical AD or that this often occurs. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • Some studies have suggested that during preclinical stages, vascular dysfunction is among the first detectable biomarker changes reported before symptomatic onset and before changes in other standard AD biomarkers, including amyloid deposition and CSF Aβ42, phosphorylated tau, and total tau.

    “Some studies have suggested that during preclinical stages, vascular dysfunction is among the first detectable biomarker changes reported before symptomatic onset and before changes in other standard AD biomarkers, including amyloid deposition and CSF A 𝛃 42, phosphorylated tau (pTau), and total tau (285, 421).”

    From Blood-Brain Barrier: From Physiology to Disease and Back (2019) · cites this paper as [285]

    The Results (‘Multifactorial biomarker ordering in LOAD progression’; page unavailable) place vascular dysregulation ahead of amyloid deposition in abnormality magnitude and compare it with CSF Aβ1–42, tau and ptau. But they report memory-impairment symptoms from very early disease stages; the paper does not establish that vascular changes were detected before symptomatic onset. (LLM, conf=0.86)

  • AD risk factors such as aging, hypertension, diabetes, and apolipoprotein E4 genotype lead to cerebrovascular damage, inducing blood-brain barrier damage and brain perfusion reduction.

    “Hit one, the AD risk factors such as aging, hypertension, diabetes, and apolipoprotein E4 (ApoE4) genotype lead to cerebrovascular damage, inducing blood‐brain barrier (BBB) damage and brain perfusion reduction.[ 4 , 6 ]”

    From Multifunctional Nanostructure RAP‐RL Rescues Alzheimer's Cognitive Deficits through Remodeling the Neurovascular Unit (2021) · cites this paper as [4]

    The Discussion (page unavailable) reports age-dependent blood–brain barrier breakdown, and the Results discuss insulin-related and oxidative-stress pathways that may affect the barrier. The paper also studies cerebral blood flow as a measure of vascular dysregulation. It does not establish that hypertension, diabetes, and ApoE4 each cause cerebrovascular damage, nor that such damage causes both barrier damage and reduced perfusion; the Discussion explicitly cautions that its analysis does not reveal direct causal relationships.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
