Active clinical trials for "Stroke"

Dysphagia or swallowing difficulty is common after stroke occurring in 25-78% of stroke survivors depending on the anatomic location of the stroke and the diagnostic test used. There are no universally accepted methods for doing a screen test at the bedside in the immediate setting after stroke. This study will assess the reliability of a bedside screen in terms of reproducibility of results between 2 independent screeners and in comparison to a fiberoptic study done by a speech language pathologist.

The aim of the study is to investigate patients with acute stroke prehospital with transcranial duplex ultrasound to detect an infarct of the middle cerebral artery.

The purpose is to investigate the COVID-19 prevalence, associated morbidity and long-term cognitive deficits in consecutive patients presenting with acute neurological symptoms

In this proposal, the investigators will demonstrate the feasibility and noninferiority of telerobotic ultrasonography as compared to traditional manual acquisition in performing a limited carotid Duplex examination and in carotid plaque detection.

This proposal seeks to improve the investigators' post-stroke TOC process through developing an innovative, patient informed and guided solution aimed at addressing the investigators' deep south African American population within the UAB system. The investigators will engage participants in both urban and rural Alabama through informational interviews and work to find common themes to address so that future interventions are useful to their unique needs and desires. This goes beyond simply identifying barriers and endeavors to discovering solutions.

Acute Ischemic stroke (AIS) remains a leading cause of adult disability, cognitive impairment and mortality worldwide despite the development of revascularization therapies (intravenous Tissue Plasminogen Activator (t-PA) and endovascular therapy). Thrombosis resistance after IV t-PA therapy is frequent especially in case of AIS with proximal occlusion. In recent years, neutrophil extracellular traps (NETs) have been identified as major triggers and structural factors of various forms of thrombosis. NETs are extracellular webs primarily composed of DNA from neutrophils. A recent study shows that the NETs burden in coronary thrombi is positively correlated with the infarct size and negatively correlated with electrocardiogram (ST-segment) resolution. This later study revealed that in vitro addition of DNase I accelerated the t-PA-induced thrombolysis of coronary thrombi. NETs could, in consequence, be promising targets for improved thrombolysis in AIS. The aim of this study is to assess the impact of NETs composition of thrombi retrieved during endovascular therapy in AIS patients on IV t-PA induced thrombolysis, clinical outcome and AIS etiologies.

This is a study on how acute clinical state and final clinical outcome in patients with stroke (exclusive subarachnoid hemorrhage) relate to ICP/ABP-derived pressure waveform parameters recorded during intensive care management.

Closure of Patent Foramen Ovale with the AMPLATZER® PFO OCCLUDER in patients with at least two cryptogenic strokes due to presumed paradoxical embolism through a patent foramen ovale and who have failed conventional therapy.

The purpose of this study is to use an intravenous infusion of allogeneic human mesenchymal stem cells (Allo-hMSCs) to treat an acute ischemic stroke condition.

The main goal of this program of research is to advance our understanding of how the severely damaged brain changes over the first 12-months post stroke. The investigators will determine 'who recovers', 'who does not recover', and 'why'
