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 ...

Nitrite supplementation alleviates cerebrovascular dysfunction in chronically stressed mice, but cognitive decline remains

Experimental Physiology, EarlyView.
Abstract This study aimed to determine whether sodium nitrite supplementation prevented chronic stress‐induced cerebrovascular dysfunction and cognitive decline. We hypothesize that nitrite supplementation will prevent the oxidative environment and cerebrovascular dysfunction associated with chronic stress and maintain cognitive health.

The acute effect of two exercise modalities on neurocognitive responses in postmenopausal women: A randomized controlled trial

Experimental Physiology, EarlyView.
Abstract Menopause‐related cognitive decline, often worsened by vasomotor symptoms (VMS), might be mitigated by high cardiorespiratory fitness (CRF). Although acute exercise supports neurocognitive function, its effects vary by exercise and individual characteristics.

Individuals with persisting post‐concussion symptoms with physiological subtype demonstrate altered cardiovascular and autonomic responses to face cooling

Experimental Physiology, EarlyView.
Abstract Individuals with persisting post‐concussion symptoms with physiological subtype (PPCS‐P) demonstrate exercise intolerance due to exacerbation of concussion‐like symptoms during incremental exercise. We tested the hypothesis that individuals with PPCS‐P (n = 12) would have a blunted cardiac autonomic response to face cooling compared to healthy

Optimizing cerebrovascular endothelial health through shear stress modulation

Experimental Physiology, EarlyView.
Abstract The endothelium plays a pivotal role in regulating cerebrovascular blood flow, and its dysfunction increases the risk of cerebrovascular disease. Endothelial shear stress, a primary mechanical stimulus for endothelial nitric oxide production, is a key modulator of vascular adaptation.

Modulation of cerebral blood flow and cognition by hyperthermia and hypoxia: An electroencephalographic event‐related potentials perspective

Experimental Physiology, EarlyView.
Abstract Cerebral blood flow (CBF) is essential for sustaining neuronal metabolism and cognitive performance; however, the precise relationship between perfusion and cognition remains unclear. Although ageing and disease are associated with progressive declines in CBF and cognitive impairment, the acute effects of altered CBF under environmental ...
