Uncovering the impact of the cardiovascular system on cerebrovascular health using MRI

Experimental Physiology, EarlyView.
Abstract Human cerebrovasculature is finely tuned to enable local changes in blood flow to meet the brain's demands, whilst protecting the brain from systemic changes in blood pressure, both acutely during a heartbeat and chronically over time. This review summarises cerebrovascular structure and function, their role in disease and neurodegeneration ...

S-Nitrosoglutathione reduces asymptomatic embolization after carotid angioplasty [PDF]

, 2002
Background: The major complication of carotid angioplasty is embolic stroke, which may occur after balloon inflation and deflation or in the early postintervention period.

Identification and Quantification of Patent Foramen Ovale-Mediated Shunts: Echocardiography and Transcranial Doppler.

Interventional Cardiology Clinics, 2017
Once deemed benign, patent foramen ovale (PFO)-mediated right-to-left shunting has now been linked to stroke, migraine, and hypoxemia. Contrast transesophageal echocardiography is considered the standard technique for identifying a PFO, allowing ...

Individuals with persisting post‐concussion symptoms with physiological subtype demonstrate altered cardiovascular and autonomic responses to face cooling

Experimental Physiology, EarlyView.
Abstract Individuals with persisting post‐concussion symptoms with physiological subtype (PPCS‐P) demonstrate exercise intolerance due to exacerbation of concussion‐like symptoms during incremental exercise. We tested the hypothesis that individuals with PPCS‐P (n = 12) would have a blunted cardiac autonomic response to face cooling compared to healthy

Robot-assisted image-guided transcranial magnetic stimulation for somatotopic mapping of the motor cortex: a clinical pilot study. [PDF]

, 2009
Shape and exact location of motor cortical areas varies among individuals. The exact knowledge of these locations is crucial for planning of neurosurgical procedures.

Optimizing cerebrovascular endothelial health through shear stress modulation

Experimental Physiology, EarlyView.
Abstract The endothelium plays a pivotal role in regulating cerebrovascular blood flow, and its dysfunction increases the risk of cerebrovascular disease. Endothelial shear stress, a primary mechanical stimulus for endothelial nitric oxide production, is a key modulator of vascular adaptation.

Genetic, laboratory and clinical risk factors in the development of overt ischemic stroke in children with sickle cell disease

Hematology, Transfusion and Cell Therapy, 2018
Cerebrovascular disease, particularly stroke, is one of the most severe clinical complications associated with sickle cell disease and is a significant cause of morbidity in both children and adults.

Heparin and air filters reduce embolic events caused by intra-arterial cerebral angiography - A prospective, randomized trial [PDF]

, 2004
Background-Intra-arterial cerebral angiography is associated with a low risk for neurological complications, but clinically silent ischemic events after angiography have been seen in a substantial number of patients.Methods and Results-In a prospective ...

Linking dynamic cerebral autoregulation and inhibitory executive function: Role of modifiable behaviours

Experimental Physiology, EarlyView.
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 ...

Role of transcranial Doppler in neuroradiological treatment of intracranial vasospasm.

, 1993
BACKGROUND AND PURPOSE: The expanded role of interventional neuroradiological treatment for post-subarachnoid hemorrhage vasospasm has highlighted the diagnostic utility of transcranial Doppler studies in this condition.
