Fetal Cerebral Blood Flow (Dys)autoregulation [PDF]

Diagnostics
Background: As an extremely sensitive organ, particularly during in utero development, the brain has intrinsic systems to reduce the risk of cerebral damage in cases of insult, such as energy deprivation, due to a mechanism of positive balance in ...

Regulation of Cerebral Blood Flow [PDF]

International Journal of Vascular Medicine, 2011
The control of cerebral blood flow is complex, and only beginning to be elucidated. Studies have identified three key regulatory paradigms. The first is cerebral pressure autoregulation, which maintains a constant flow in the face of changing cerebral ...

Phase contrast-derived cerebral blood flow is associated with neurodegeneration and cerebrovascular injury in older adults [PDF]

Frontiers in Neuroscience
Global cerebral blood flow and the local delivery of blood through the vascular network are essential to maintain brain and cognitive health throughout the lifespan.

Understanding Cerebral Blood Flow Dynamics for Alzheimer's Disease Prevention Through Acute Exercise (flADex): Protocol for a Randomized Crossover Trial [PDF]

Brain and Behavior
Introduction Alzheimer's disease (AD) is a leading cause of disability worldwide. Alterations in cerebral blood flow (CBF) and AD blood biomarkers are fundamental at early stages of AD.

Nimodipine augments cerebrovascular reactivity in aging but runs the risk of local perfusion reduction in acute cerebral ischemia

Frontiers in Aging Neuroscience, 2023
IntroductionThe efficacy of cerebrovascular reactivity (CVR) is taken as an indicator of cerebrovascular health.Methods and ResultsWe found that CVR tested with the inhalation of 10 % CO2 declined in the parietal cortex of 18-20-month-old rats.

Cerebral blood flow velocity is associated with endothelial function in men [PDF]

Journal of Men's Health, 2021
Background and objective: Reduction in cerebral blood flow with aging leads to cognitive decline and brain atrophy. Cerebrovascular hemodynamics are associated with vascular function.

Integrative cerebral blood flow regulation in ischemic stroke

Journal of Cerebral Blood Flow and Metabolism, 2021
Optimizing cerebral perfusion is key to rescuing salvageable ischemic brain tissue. Despite being an important determinant of cerebral perfusion, there are no effective guidelines for blood pressure (BP) management in acute stroke.

Modeling of intracranial vessels and Simulation of cerebral blood flow [PDF]

E3S Web of Conferences, 2020
The stable regulation of cerebral blood flow plays an important role in the normal operation of brain function. The disturbance of cerebral blood flow automatic regulation will lead to brain injury and lead to cerebrovascular disease. Therefore, it is of

Comparison of cerebral blood flow in subjects with and without chronic obstructive pulmonary disease from the population-based Rotterdam Study

BMJ Open, 2021
Objectives Patients with chronic obstructive pulmonary disease (COPD) are at increased risk of cerebrovascular disease, which might be associated with decreases in cerebral blood flow. Since studies examining cerebral blood flow in COPD remain scarce and

On the Normalization of Cerebral Blood Flow [PDF]

Journal of Cerebral Blood Flow & Metabolism, 2013
Cerebral blood flow (CBF) is the most common parameter for the quantification of brain's function. Literature data indicate a widespread dispersion of values that might be related to some differences in the measurement conditions that are not properly taken into account in CBF evaluation.
