The impact of blood pressure variability on neurovascular function
Intravascular pressure drives perfusion, which is critical for optimal neuronal function. High blood pressure (hypertension), however, is a risk factor for cognitive decline. Emerging evidence identifies increased blood pressure variability (IBPV), before the development of hypertension, as a strong predictor for vascular cognitive impairment and dementia. The mechanism whereby IBPV mediates cognitive decline is unknown and is the subject of this novel proposal. The myogenic response of cerebral arterioles protects the brain from blood pressure fluctuations that could cause hyper- or hypoperfusion. Mechanosensory mechanisms are essential in this process, but the impact of chronic blood…
