Uncovering the impact of the cardiovascular system on cerebrovascular health using MRI

Experimental Physiology, EarlyView.
Abstract Human cerebrovasculature is finely tuned to enable local changes in blood flow to meet the brain's demands, whilst protecting the brain from systemic changes in blood pressure, both acutely during a heartbeat and chronically over time. This review summarises cerebrovascular structure and function, their role in disease and neurodegeneration ...

Impaired Windkessel function and proximal aortic stiffness: Linking vascular ageing to cognitive decline

Experimental Physiology, EarlyView.
Abstract Central arterial stiffening, particularly of the proximal aorta, is increasingly recognised as a pivotal contributor to cardiovascular disease, dementia, and mild cognitive impairment. Loss of Windkessel function amplifies pulsatile pressure, reduces diastolic perfusion and accelerates microvascular damage in the brain.

Lower cerebral blood flow but not cerebrovascular response in elastin haploinsufficient mice

Experimental Physiology, EarlyView.
Abstract Elastin insufficiency is associated with structural differences in the large elastic arteries and cerebral artery dysfunction. However, previous studies have not assessed potential sex differences in cerebrovascular function. We measured cerebral blood flow (CBF) using arterial spin labeling MRI at rest and in response to hypercapnia challenge

Effect of a single exercise bout on fasting cerebral blood flow and brain insulin sensitivity in middle‐aged to older adults

Experimental Physiology, EarlyView.
Abstract Reductions in brain insulin sensitivity and cerebral blood flow (CBF) have emerged as potential factors contributing to Alzheimer's disease and related dementia. However, no work has tested whether a single bout of exercise can raise brain insulin sensitivity in at‐risk adults. The aim of the study was to test whether a single bout of exercise
