Quantitative analysis of systemic perfusion and cerebral blood flow in the modeling of aging and orthostatic hypotension

Frontiers in Physiology
Introduction: Orthostatic hypotension (OH) is common among the older population. The mechanism hypothesized by OH as a risk factor for cognitive decline and dementia is repeated transient cerebral blood flow deficiency.

Cerebral Blood Flow and Migraine

Pediatric Neurology Briefs, 2008
Blood flow in the basilar and internal carotid arteries and diameters of middle meningeal, carotid, and cerebral arteries were measured using 3Tesla magnetic resonance angiography, at baseline, during infusion of nitroglycerin or placebo, and during a ...

Vestibular Effects on Cerebral Blood Flow [PDF]

, 2011
Background: Humans demonstrate a number of unique adaptations that allow for the maintenance of blood pressure and brain blood flow when upright. While several physiological systems, including cerebral autoregulation, are involved in this adaptation the ...

Effects of Biological Sex and Age on Cerebrospinal Fluid Markers—A Retrospective Observational Study

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Cerebrospinal fluid (CSF) analysis is a key diagnostic tool for neurological diseases. To date, only a few studies have investigated in larger cohorts the effect of age and biological sex on diagnostic markers extracted from CSF. Methods For this retrospective observational study, 4163 CSF findings (2012–2020) were evaluated.

The pathogenesis of microglia in traumatic brain injury

Chinese Journal of Contemporary Neurology and Neurosurgery
The mechanism of secondary injury after tramatic brain injury (TBI) is related to inflammation reation, oxidative stress, inflammasome, and so on, and microglia are closely related to it. Microglia, as macrophage in the nervous system, participate in the

ASYMMETRY OF THE BRAIN AT ADAPTATION TO HYPOXIA

Medična Informatika ta Inženerìâ, 2012
Association between cerebral blood flow and higher nervous activity in people at different stages of adaptation to the midlands was studied. Investigation were performed before, during and after a three-week stay in the mountains at an altitude of 2100 m,

Control of Cerebral Blood Flow by Blood Gases

Frontiers in Physiology, 2021
Cerebrovascular reactivity can be measured as the cerebrovascular flow response to a hypercapnic challenge. The many faceted responses of cerebral blood flow to combinations of blood gas challenges are mediated by its vasculature’s smooth muscle and can ...

Moderate hyperventilation during intravenous anesthesia increases net cerebral lactate efflux [PDF]

, 2014
BACKGROUND:: Hyperventilation is known to decrease cerebral blood flow (CBF) and to impair cerebral metabolism, but the threshold in patients undergoing intravenous anesthesia is unknown. The authors hypothesized that reduced CBF associated with moderate

Spinal Cord Infarction Versus Idiopathic Transverse Myelitis: Clinical, Radiological, and Functional Insights From a Retrospective Cohort Study

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Introduction Spinal cord infarction (SCI) is a rare but devastating myelopathy, characterized by a high disability rate and an unfavorable prognosis. It has often been underdiagnosed and misdiagnosed as idiopathic transverse myelitis (ITM). This study aimed to describe the clinical features, radiological biomarkers, treatments, and functional ...

Pulmonary consequences of experimentally induced stroke: differences between global and focal cerebral ischemia

Frontiers in Physiology
IntroductionCerebral ischemia leads to multiple organ dysfunctions, with the lungs among the most severely affected. Although adverse pulmonary consequences contribute significantly to reduced life expectancy after stroke, the impact of global or focal ...
