Impaired Cerebral Autoregulation in Children. [PDF]
Pediatr NeurolManaging acute brain injury involves protecting the brain from secondary injury by addressing the mismatch between metabolic demand and cerebral perfusion. Observational studies have associated impaired cerebral autoregulation, a physiological process governing the regulation of cerebral blood flow, with unfavorable neurological outcomes in both ...

Cerebrovascular Impedance as a Function of Cerebral Perfusion Pressure
IEEE Open Journal of Engineering in Medicine and Biology, 2023 Goal: Cerebrovascular impedance is modulated by a vasoactive autoregulative mechanism in response to changes in cerebral perfusion pressure. Characterization of impedance and the limits of autoregulation are important biomarkers of cerebral health.

Cerebral autoregulation in Alzheimer's disease [PDF]
Journal of Cerebral Blood Flow & Metabolism, 2011 Cerebral autoregulation aims to stabilize blood flow to the brain during variations in perfusion pressure, thus protecting the brain against the risks of low or high systemic blood pressure. This vital mechanism is severely impaired in the transgenic mouse model of Alzheimer's disease (AD) that abundantly produces amyloid-β peptide β1-42.

Temporal Course of Cerebral Autoregulation in Patients With Narcolepsy Type 1: Two Case Reports
Frontiers in Neurology, 2019 Cerebral autoregulation is the mechanism by which constant cerebral blood flow is maintained despite changes in arterial blood pressure. In the two presented cases, cerebral autoregulation was impaired in patients with narcolepsy type 1, and both ...

Cerebral autoregulation, brain injury, and the transitioning premature infant [PDF]
, 2017 Improvements in clinical management of the preterm infant have reduced the rates of the two most common forms of brain injury, such as severe intraventricular hemorrhage and white matter injury, both of which are contributory factors in the development ...

BMC Neurology, 2020 Background Venous sinus stenosis (VSS) is a type of cerebral venous vascular disease. Cerebral autoregulation is an indicator of cerebral arterial function. The cerebral circulatory system is composed of the venous system and arterial system.

A stochastic delay differential model of cerebral autoregulation [PDF]
, 2015 Mathematical models of the cardiovascular system and of cerebral autoregulation (CAR) have been employed for several years in order to describe the time course of pressures and flows changes subsequent to postural changes. The assessment of the degree of
