Abstract

Increasing evidence recognizes Alzheimer's disease (AD) as a multifactorial and heterogeneous disease with multiple contributors to its pathophysiology, including vascular dysfunction. The recently updated AD Research Framework put forth by the National Institute on Aging–Alzheimer's Association describes a biomarker‐based pathologic definition of AD focused on amyloid, tau, and neuronal injury. In response to this article, here we first discussed evidence that vascular dysfunction is an important early event in AD pathophysiology. Next, we examined various imaging sequences that could be easily implemented to evaluate different types of vascular dysfunction associated with, and/or contributing to, AD pathophysiology, including changes in blood‐brain barrier integrity and cerebral blood flow. Vascular imaging biomarkers of small vessel disease of the brain, which is responsible for >50% of dementia worldwide, including AD, are already established, well characterized, and easy to recognize. We suggest that these vascular biomarkers should be incorporated into the AD Research Framework to gain a better understanding of AD pathophysiology and aid in treatment efforts.

  • The two-hit vascular hypothesis proposes that cerebrovascular dysfunction plays an important role in the progression of AD.

    “Accordingly, cerebrovascular dysfunction has been put forward three decades ago, and two‐hit vascular hypothesis was proposed to demonstrate the important role of cerebrovascular dysfunction in the progression of AD.[ 5 ]”

    From Multifunctional Nanostructure RAP‐RL Rescues Alzheimer's Cognitive Deficits through Remodeling the Neurovascular Unit (2021) · cites this paper as [5]

    The section “Vascular dysfunction and vascular biomarkers in AD” says cerebrovascular dysfunction is prominent in AD and describes vascular factors acting with amyloid burden to promote cognitive decline. This supports the claimed importance of vascular dysfunction, but our copy does not identify a “two-hit vascular hypothesis” or substantiate the sentence’s “three decades ago” dating.

  • Clinical distinctions between Alzheimer's and vascular dementias are often blurred by frequent co-association.

    “It is no wonder then that the clinical distinctions between Alzheimer’s and the vascular dementias often is blurred by their frequent co-association (102).”

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.
