Abstract

Vascular dementia (VaD) is a history-laden disease entity that dates back to the 19th century when arteriosclerotic brain atrophy due to hardening of the arteries was perceived as the major cause of senile dementia. Its existence had been overshadowed by the emergence of Alzheimer's disease (AD) in the past century and research on AD dominated the field of dementia. Interest in VaD has been revived in recent years as vascular lesions have been shown to make great contributions to the development of dementia, particularly in the elderly. VaD has now evolved into the concept of vascular cognitive impairment (VCI), which encompasses not only VaD but also AD with cerebrovascular disorder and VCI with no dementia. The concept of VCI is intended to maximize the therapeutic potential in dementia management because the vascular component may be amenable to therapeutic intervention particularly in the early stages of cognitive impairment. Subcortical ischemic vascular dementia (SIVD) is pathologically driven by severe stenosis and the occlusion of small vessels that culminate into white matter ischemia and multiple lacunar infarctions in the subcortical structures. The relatively slow progression of symptoms and clinical manifestations associated with cholinergic deficits often make the differentiation of SIVD from AD difficult. The recent development of in vivo amyloid imaging enabled further pathological breakdown of SIVD into pure SIVD and mixed dementia with subcortical ischemia based on the absence or existence of amyloid pathology in the brain. In this article, the authors reviewed the emerging concepts of VaD/VCI and the clinical manifestations, biomarkers, treatments, and preclinical models of SIVD based on the pathophysiologic mechanisms of the disease.

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.
