INFOMATAS multi-center systematic review and meta-analysis individual patient data of dynamic cerebral autoregulation in ischemic stroke

open access: yes, 2020
Rationale: Disturbances in dynamic cerebral autoregulation after ischemic stroke may have important implications for prognosis. Recent meta-analyses have been hampered by heterogeneity and small samples.

A new model-free index of dynamic cerebral blood flow autoregulation. [PDF]

open access: yesPLoS ONE, 2014
The classic dynamic autoregulatory index (ARI), proposed by Aaslid and Tiecks, is one of the most widely used methods to assess the efficiency of dynamic cerebral autoregulation. Although this index is often used in clinical research and is also included

Dynamic Cerebral Autoregulation After Carotid Endarterectomy

open access: yesJournal of Endovascular Therapy, 2023
Objective: Studies have shown that dynamic cerebral autoregulation (dCA) is impaired in patients with severe internal carotid artery (ICA) stenosis and that carotid endarterectomy (CEA) may improve dCA in these patients. However, the time course of dCA changes in patients after CEA remains unclear.

Wavelet coherence analysis of dynamic cerebral autoregulation in neonatal hypoxic–ischemic encephalopathy

open access: yesNeuroImage: Clinical, 2016
Cerebral autoregulation represents the physiological mechanisms that keep brain perfusion relatively constant in the face of changes in blood pressure and thus plays an essential role in normal brain function.

Dynamic Cerebral Autoregulation in Sick Newborn Infants [PDF]

open access: yesPediatric Research, 2000
The sick newborn infant is vulnerable to brain injury and impaired cerebral autoregulation is thought to contribute to this. Coherent averaging is a method of measuring the dynamic cerebral autoregulatory response that is particularly suitable for neonates.

Dynamic cerebral autoregulation is impaired in Veterans with Gulf War Illness: A case-control study. [PDF]

open access: yesPLoS ONE, 2018
Neurological dysfunction has been reported in Gulf War Illness (GWI), including abnormal cerebral blood flow (CBF) responses to physostigmine challenge. However, it is unclear whether the CBF response to normal physiological challenges and regulation is ...

Comparison of static and dynamic cerebral autoregulation under anesthesia influence in a controlled animal model.

open access: yesPLoS ONE, 2021
The brain's ability to maintain cerebral blood flow approximately constant despite cerebral perfusion pressure changes is known as cerebral autoregulation (CA) and is governed by vasoconstriction and vasodilation.

Non-linear models for the detection of impaired cerebral blood flow autoregulation. [PDF]

open access: yesPLoS ONE, 2018
The ability to discriminate between normal and impaired dynamic cerebral autoregulation (CA), based on measurements of spontaneous fluctuations in arterial blood pressure (BP) and cerebral blood flow (CBF), has considerable clinical relevance. We studied

METHOD FOR DETERMINING THE UPPER LIMIT OF CEREBRAL AUTOREGULATION IN RATS

open access: yesФармация и фармакология (Пятигорск), 2018
The main objective of the phenomenon of cerebral autoregulation is to maintain a constant cerebral blood flow rate with changes in systemic arterial pressure in the range of 50 mmH up to 150 Mmhg.

Detection of impaired cerebral autoregulation improves by increasing arterial blood pressure variability

open access: yes, 2013
Although the assessment of dynamic cerebral autoregulation (CA) based on measurements of spontaneous fluctuations in arterial blood pressure (ABP) and cerebral blood flow (CBF) is a convenient and much used method, there remains uncertainty about its ...
