Cerebral Autoregulation in Subarachnoid Hemorrhage [PDF]
Frontiers in Neurology, 2021 Subarachnoid hemorrhage (SAH) is a devastating stroke subtype with a high rate of mortality and morbidity. The poor clinical outcome can be attributed to the biphasic course of the disease: even if the patient survives the initial bleeding emergency ...

BJA Open, 2022 Background: Cerebral autoregulation actively maintains cerebral blood flow over a range of MAPs. During general anaesthesia, this mechanism may not compensate for reductions in MAP leading to brain hypoperfusion.

Sport-Related Concussion Alters Indices of Dynamic Cerebral Autoregulation [PDF]
Frontiers in Neurology, 2018 Sport-related concussion is known to affect a variety of brain functions. However, the impact of this brain injury on cerebral autoregulation (CA) is poorly understood. Thus, the goal of the current study was to determine the acute and cumulative effects

Frontiers in Neurology, 2021 The autoregulation of cerebral blood flow protects against brain injury from transient fluctuations in arterial blood pressure. Impaired autoregulation may contribute to hypoperfusion injury in neonates and infants.

Modeling of Cerebral Blood Flow Autoregulation Using Mathematical Control Theory
Mathematics, 2022 A mathematical model of cerebral blood flow in the form of a dynamical system is studied. The cerebral blood flow autoregulation modeling problem is treated as a nonlinear control problem and the potential and applicability of the nonlinear control ...

Differentiating Dynamic Cerebral Autoregulation Across Vascular Territories
Frontiers in Neurology, 2021 Objective: Transcranial Doppler is commonly used to calculate cerebral autoregulation, but measurements are typically restricted to a single cerebral artery.

Neonatal cerebrovascular autoregulation [PDF]
Pediatric Research, 2018 Cerebrovascular pressure autoregulation is the physiologic mechanism that holds cerebral blood flow (CBF) relatively constant across changes in cerebral perfusion pressure (CPP). Cerebral vasoreactivity refers to the vasoconstriction and vasodilation that occur during fluctuations in arterial blood pressure (ABP) to maintain autoregulation.
