Isolated transient vertigo: posterior circulation ischemia or benign origin?

BMC Neurology, 2017
Background Isolated transient vertigo can be the only symptom of posterior circulation ischemia. Thus, it is important to differentiate isolated vertigo of a cerebrovascular origin from that of more benign origins, as patients with cerebral ischemia have

Wavelet Autoregulation Monitoring Identifies Blood Pressures Associated With Brain Injury in Neonatal Hypoxic-Ischemic Encephalopathy

Frontiers in Neurology, 2021
Dysfunctional cerebrovascular autoregulation may contribute to neurologic injury in neonatal hypoxic-ischemic encephalopathy (HIE). Identifying the optimal mean arterial blood pressure (MAPopt) that best supports autoregulation could help identify ...

The translational potential of experimental pharmacology for cerebrovascular disorders

Анналы клинической и экспериментальной неврологии, 2019
The efficacy of reperfusion therapy to restore cerebral blood supply in patients with ischaemic cerebrovascular disorders is well recognized. Medications with proven cerebrovascular activity, such as oxymethylethylpyridine succinate (Mexidol), nicotinoyl-

Quantitative Analysis of Brain CT Perfusion in Healthy Beagle Dogs: A Pilot Study

Veterinary Sciences, 2023
Brain computed tomography (CT) perfusion is a technique that allows for the fast evaluation of cerebral hemodynamics. However, quantitative studies of brain CT perfusion in veterinary medicine are lacking. The purpose of this study was to investigate the

Cerebrovascular Variants in Posterior Circulation [PDF]

Circulation Research, 2016
Ever since the identification of hypertension around 150 years ago, researchers have struggled to find its cause(s) with only minor successes.1 Essential, or primary, or idiopathic hypertension is historically defined as a rise in blood pressure (BP) without any known causes, which still accounts for ≈95% of all hypertension.2 Whereas multiple risk ...

Circulating Endothelial Progenitor Cells in Cerebrovascular Disease [PDF]

Journal of Clinical Neurology, 2008
Stroke is associated with high disability and mortality burdens worldwide, but there are few effective and widely available therapies. There is therefore a need to develop treatments that promote the repair and regeneration of ischemic brain tissue. In this regard, a population of adult stem cells-called endothelial progenitor cells (EPCs)-has been ...

The collaterome: A novel conceptual framework of systems biology in cerebrovascular disorders

Brain Circulation, 2015
The collaterome is the elaborate neurovascular architecture within the brain that regulates and determines the compensatory ability, response, and outcome of cerebrovascular pathophysiology.

Closed cranial window rodent model for investigating hemodynamic response to elevated intracranial pressure

Animal Models and Experimental Medicine, 2021
Background Elevated intracranial pressure (ICP) occurs in several physiological and pathological conditions, yet long‐term sequellae are not common, which implies that blood flow is preserved above ischemic thresholds.

Genetic Risk, Vascular Function, and Subjective Cognitive Complaints Predict Objective Cognitive Function in Healthy Older Adults: Results From the Brain in Motion Study

Frontiers in Integrative Neuroscience, 2020
Aging is associated with subjective memory complaints. Approximately half of those with subjective memory complaints have objective cognitive impairment.
