Altered Dynamic Functional Network Connectivity in Post‐Stroke Aphasia
ABSTRACT Objective Previous studies examining post‐stroke aphasia (PSA) patients via resting‐state functional magnetic resonance imaging (rs‐fMRI) have predominantly focused on static functional connectivity. In contrast, the current investigation aims to elucidate the alterations in dynamic functional network connectivity (dFNC) among PSA patients ...

Cerebral Blood Flow and Migraine
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 ...

ABSTRACT Background Apolipoprotein ε4 (APOE ε4) is a potent genetic risk factor for Alzheimer's disease (AD). However, its role in cerebral small vessel disease (CSVD) remains unclear. Given the clinical and pathological similarities between CSVD and AD, this study aimed to investigate the associations of APOE ε4 gene dosage with cognitive function and

The pathogenesis of microglia in traumatic brain injury
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
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,

Multiple blood flow measurements before and after carotid artery stenting via phase-contrast magnetic resonance imaging: An observational study. [PDF]
After carotid artery stenting, the procurement of information about blood flow redistribution among brain-feeding arteries and its time trend is essential to understanding a patient's physiological background and to determine their care regimen. Cerebral

Control of Cerebral Blood Flow by Blood Gases
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 ...

ABSTRACT Mutations in myelin regulatory factor (MYRF) are linked to demyelinating disorders. We report a 38‐year‐old male who developed acute symmetric leukoencephalopathy mimicking a stroke following an influenza A virus infection. While clinical symptoms markedly improved with corticosteroids, MRI revealed persistent white matter lesions, contrasting
