Visual Perception Difficulties After Stroke
The goal of this observational study is to learn how well the Oxford Visual Perception Screening (OxVPS) tool can identify stroke survivors with visual perception difficulties. The main aim is to determine the accuracy and utility of the OxVPS compared to the current gold standard assessment in stroke survivors. In …
Neurofrailty: A Study of Late-onset Epilepsy and Its Associations
We don't know a great deal about why some people develop seizures in adulthood, but some researchers think that it might tell us something about the brain. A small number of people with first seizure in adulthood go on to experience problems like stroke or dementia later in life. However, …
AFLETES-MRI: A Cardiac and Cerebral Magnetic Resonance Imaging Study in Athletes With Atrial Fibrillation
Participation in exercise improves cardiovascular health. However, long-term endurance exercise may increase the risk of an irregular heart rhythm called atrial fibrillation (AF). In AF, blood flow is altered, increasing the risk of clot formation in the heart which may enter the circulation and cause a stroke. The risk of …
Evaluation of Small Vessel Disease by 3D-rotational Angiography
This study is aimed to elucidate the factors affecting the remodeling process of arteriolosclerosis under current practice recommendations. Such knowledge may improve the understanding of cerebral small vessel disease (cSVD) mechanism, define pharmacological therapy and suggest treatment target.
Influence of Brain Oscillation-Dependent TMS on Motor Function
Background When people have a stroke, they often have difficulty moving their arms and hands. Transcranial magnetic stimulation (TMS) can improve how well people with and without stroke can move their arms and hands. But the effects of TMS are minor, and it doesn t work for everyone. Researchers want …
The Origin and Role of Thromboembolism in the Pathogenesis of Ischaemic Stroke
Ischaemic stroke is usually due to occlusion of a cerebral artery by thrombus. However, it is often difficult to identify the source of thrombus, or to confirm thrombus as a cause of ischaemic stroke. Moreover, it is debated whether thrombosis plays any role in certain types of stroke such as …
Association Between Stroke and Adrenal Incidentalomas
Adrenal incidentalomas (AIs) are commonly encountered in transsection imaging which purpose not for suspected adrenal disease. However, part of AIs in patients is associated with Stroke. Stroke is a diseases which could cause of disability and death worldwide. In clinical practice, detailed information about the association between stroke and AIs …
Study of Hemodynamic Markers of Upper Extremity Motor Dysfunction in Stroke Patients Using Functional Near Infrared Spectroscopy (fNIRS)
The aim of the study was to explore potential pathways for recovery and adaptation of the motor cortex by examining cerebral blood flow characteristics and hemodynamic markers analyzed by functional near-infrared spectroscopy (fNIRS) in patients with hemiparesis after stroke. Participants in the study performed a simple stimulus-response task several times …
Diagnostic Performance Study of the EMVision Emu™ Brain Scanner in the Detection of Intracranial Hemorrhage in Suspected Stroke Patients
The purpose of this research is to evaluate a new investigational device for the diagnosis of stroke, the EMVision emu™ Brain Scanner. Stroke is the result of a blood clot stopping the normal flow of blood in the brain (ischaemic stroke) or a breakage in a blood vessel causing bleeding …
The "MyoThrombus" Study
Left ventricular thrombus is a recognised complication of acute myocardial infarction, associated with stroke, recurrent myocardial infarction and adverse cardiac remodelling. The prevention, treatment and resolution of thrombus is hampered by a lack of understanding of its initiation, propagation and dissolution. Advanced non-invasive imaging holds major promise in improving our …
