Noninvasive Optical Measurements of Dynamic Cerebral Autoregulation by Inducing Oscillatory Cerebral Hemodynamics [PDF]

Frontiers in Neurology, 2021
Objective: Cerebral autoregulation limits the variability of cerebral blood flow (CBF) in the presence of systemic arterial blood pressure (ABP) changes.

Dynamic Cerebral Autoregulation Post Endovascular Thrombectomy in Acute Ischemic Stroke

Brain Sciences, 2020
The development of the endovascular thrombectomy (EVT) technique has revolutionized acute stroke management for patients with large vessel occlusions (LVOs). The impact of successful recanalization using an EVT on autoregulatory profiles is unknown.

Dynamic cerebral autoregulation after intracerebral hemorrhage: A case-control study [PDF]

BMC Neurology, 2011
Background Dynamic cerebral autoregulation after intracerebral hemorrhage (ICH) remains poorly understood. We performed a case-control study to compare dynamic autoregulation between ICH patients and healthy controls. Methods Twenty-one patients (66 ± 15

Assessment of control and performance of biomedical systems [PDF]

, 2010
Introduction: In biomedical systems repeated measurements are often collected, thus presenting a statistical challenge due to high temporal correlation. This research investigates the potential utility of two distinct statistical methodologies in their ...

Linking dynamic cerebral autoregulation and inhibitory executive function: Role of modifiable behaviours. [PDF]

Exp Physiol
Abstract Dynamic cerebral autoregulation (dCA) stabilises cerebral blood flow (CBF) against rapid fluctuations in perfusion pressure and may serve as a key physiological mediator of cognitive function. Inhibitory executive function, a core domain essential for goal‐directed behaviour, is influenced by modifiable lifestyle factors such as physical ...

Sex differences in dynamic cerebral autoregulation responses to resistance and endurance training in humans. [PDF]

Exp Physiol
Abstract Exercise maintains brain health and reduces the risk of cerebrovascular diseases, such as stroke and dementia. The benefits of different ‘modalities’ of exercise on male and female cerebral autoregulation are unclear. In this study, we compared adaptations in dynamic cerebral autoregulation (dCA) during spontaneous and forced oscillations in ...

The consistency of invasive and non-invasive arterial blood pressure for the assessment of dynamic cerebral autoregulation in NICU patients

Frontiers in Neurology, 2022
BackgroundStudies of the clinical application of dynamic cerebral autoregulation show considerable variations, and differences in blood pressure devices may be one of the reasons for this variation.

Changes in cerebral autoregulation and vasoreactivity after surgical aortic valve replacement: a prospective study

Experimental Physiology, 2023
Surgical aortic valve replacement (SAVR) alters the natural course of severe aortic stenosis (AS). In this study, we aimed to determine the effects of the disease on dynamic cerebral autoregulation and vasoreactivity (VR) and to assess their changes ...
