Small-caliber cerebral vessels change their diameters in response to alterations of key
metabolite concentrations such as carbon dioxide or oxygen. This phenomenon, termed the …

BACKGROUND AND OBJECTIVE: Vasomotor reactivity (VMR) represents the
autoregulatory capacity of cerebral vessels and its clinical significance has been reported in …

Background. Recent studies have shown that cerebral vascularity may be impaired in
Alzheimer's disease. Cerebral vasomotor reactivity could be an important biomarker for this …

Cerebrovascular reactivity (CVR) magnetic resonance imaging (MRI) probes cerebral
haemodynamic changes in response to a vasodilatory stimulus. CVR closely relates to the …

The regulation of cerebral blood flow (CBF) is a complex and tightly controlled function
ensuring delivery of oxygen and nutrients and removal of metabolic wastes from brain …

vasomotor reactivity and dementia after ischemic stroke. Acta Neurol Scand: 2010: 122: 383 …

ABSTRACT Background and Purpose. The relationships between cerebral vasomotor
reactivity (CVR) and white matter lesions (WMLs) were investigated mainly in patients with …

Background Reduced cerebral blood flow and microvascular abnormalities have been
suggested as the vascular pathogenesis of Alzheimer's disease (AD). Transcranial Doppler …

Cerebral vasomotor reactivity (CVR) represents the capability of cerebral vessels to modify
their caliber in response to a stimulus. Impaired CVR is associated with an increased risk for …

Vascular smooth muscle cells (VSMCs) are the key moderators of cerebrovascular dynamics
in response to the brain's oxygen and nutrient demands. Crucially, VSMCs may provide a …
