Abstract

Hypertension in the elderly substantially increases both the risk of vascular cognitive impairment (VCI) and Alzheimer's disease (AD); however, the underlying mechanisms are not completely understood. This review discusses the effects of hypertension on structural and functional integrity of cerebral microcirculation, including hypertension-induced alterations in neurovascular coupling responses, cellular and molecular mechanisms involved in microvascular damage (capillary rarefaction, blood-brain barrier disruption), and the genesis of cerebral microhemorrhages and their potential role in exacerbation of cognitive decline associated with AD. Understanding and targeting the hypertension-induced cerebromicrovascular alterations that are involved in the onset and progression of AD and contribute to cognitive impairment are expected to have a major role in preserving brain health in high-risk older individuals.

  • Aging-induced dysregulation of microvascular endothelial function and phenotype critically contributes to the pathogenesis of both vascular cognitive impairment (VCI) and Alzheimer's disease (AD).

    “There is strong evidence that aging-induced dysregulation of microvascular endothelial function and phenotype critically contributes to the pathogenesis of both vascular cognitive impairment (VCI) and Alzheimer ' s disease (AD)”

    From Single-cell RNA sequencing identifies senescent cerebromicrovascular endothelial cells in the aged mouse brain (2020) · cites this paper as Csiszar et al. 2017

    The Introduction (page not available) states that old age promotes microvascular endothelial dysfunction and is associated with dysregulated endothelial angiogenesis. It links these changes to microvascular injury in older patients with AD, but frames that link as likely and does not establish that aging-induced endothelial changes critically cause both VCI and AD. The paper’s emphasis is on hypertension and its interaction with aging and AD. (LLM, conf=0.83)

  • Aging decreases capillary density (microvascular rarefaction) in the brain.

    “Aging decreases capillary density (known as ' microvascular rarefaction ' ) (Csiszar et al. 2017; Tarantini et al. 2016; Tucsek et al. 2014a; Ungvari et al. 2013a; Banki et al. 2015; Toth et al. 2017)”

    From Single-cell RNA sequencing identifies senescent cerebromicrovascular endothelial cells in the aged mouse brain (2020) · cites this paper as Csiszar et al. 2017

    The Introduction defines cerebromicrovascular rarefaction as a decline in brain capillarization and says that old age significantly exacerbates hypertension-induced rarefaction. It does not state that aging alone decreases brain capillary density, so the claim omits an important condition. (LLM, conf=0.86)

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.
