Active clinical trials for "Stroke"

This multinational registry (3 USA, 2 European centers) will capture in the ED continuous non invasive hemodynamic monitoring (using Nexfin finger cuff technology) of patients presenting with acute heart failure, stroke syndromes and systemic infection. Patients will be observed after their Emergency Department (ED) disposition to determine clinical outcomes (length of stay in the hospital, the development of any organ dysfunction, mortality and need for unscheduled medical care within the ensuing 30 days). It is anticipated that specific ED hemodynamic profiles will be predictive of better clinical outcomes than others. This information will provide the outcome data needed to design future therapeutic trials that will evaluate the effect of ED hemodynamic manipulations on overall patient management and outcomes.

The purpose of this research is to utilize functional magnetic resonance imaging (fMRI) to investigate brain reorganization for language behavior in stroke patients with aphasia. A primary focus of the study is on recovery of nonfluent propositional speech and naming in chronic aphasia patients. The fMRI technique is used to examine activation in the left hemisphere (LH) and right hemisphere (RH), during recovery of specific language behaviors in chronic nonfluent aphasia patients.

This study will test the hypothesis whether patients with unclear-onset stroke (UnCLOS) treated with thrombolysis could achieve a prespecified rate of good clinical outcome. The secondary hypothesis is that the efficacy outcomes in UnCLOS group would be superior to those in historical UnCLOS group from prospective stroke registries.

The objective of this trial is to guarantee a follow-up of all stroke and transient ischemic attack (TIA) patients. With this follow-up assessment long term effects of therapy and prevention measures can be detected and monitored. It is part of quality assurance.

Prospective observational multicenter study to evaluate copeptin as a prognostic marker in patients with an acute cerebrovascular event. It includes four groups of patients, mainly depending on type of initial therapy (intra-arterial thrombolysis, intravenous thrombolysis, conservative treatment, TIA). The study takes place at the Emergency and neurological Department of the University of Bern, Switzerland; Department of Neurology, Goethe University of Frankfurt a.M. (Germany). Further participating centers are under discussion

Patients with blockage of the blood vessels that supply blood to the back of the brain, known as vertebrobasilar disease (VBD), are at risk of having a stroke or temporary symptoms of a stroke known as transient ischemic attack (TIA). The risk of repeated stroke associated with VBD may be affected by several risk factors, including the degree to which the blockage reduces the blood flow to the brain. Patients with VBD have different levels of blockage ranging from partial blockage to complete blockage, which can affect the blood flow to the brain by variable amounts. The purpose of this research is to determine if patients with symptomatic VBD who demonstrate low blood flow to the back of the brain on magnetic resonance (MR)imaging are at higher risk of developing another stroke or TIA than patients with normal blood flow.

In an observational multi-centre study (HEROS), the effects of starting treatment with rosuvastatin were assessed, on low-density lipoprotein cholesterol (LDL-C) goal achievement, in patients with a dissimilar high-risk profile who had not been treated with cholesterol lowering drugs at least in the past three months. Also set-up costs of rosuvastatin treatment and proportional changes in LDL-C and high-density lipoprotein cholesterol (HDL-C) were studied.

About 50% of stroke survivors have limitations in their activities of daily living on return to the community. Family caregivers provide invaluable support to these individuals during their recovery and rehabilitation. Unfortunately, there is no standard clinical practice to prepare caregivers for this role and, as a result, many experience stress and poor health that can compromise stroke survivor recovery and threaten the sustainability of the care needed to thrive in their home. To address this gap, the investigators have developed the Timing it Right Stroke Family Support Program that aims to meet the evolving needs of caregivers. The objective of this multi-province randomized controlled trial is to determine if this program delivered across the stroke care continuum improves caregivers' sense of being supported and emotional well-being. Ultimately this program could be used by stroke care programs from across Canada.

The purpose of this study is to evaluate the utility of measuring coagulation factor activities in the setting of acute ischemic stroke, as potential markers of inherited thrombotic risk. The investigators will determine if relationships exist between coagulation factors, including factor VIII, factor IX, and factor XI and clinical diagnosis, classification, and outcome. The investigators will determine if any significant elevations of these factor activities are independent thrombotic risk factors. Null Hypothesis: There is no statistical difference between coagulation factors, including factors VIII, IX, or XI activity levels in patients having acute ischemic stroke as compared to acute stroke mimics.

The purpose of this study is to determine whether injections of botulinum toxin (commonly known as BOTOX®) into the affected hand of Stroke patients, while targeting the muscles controlling the hand, will lead to improved use of the hand when compared to injections of placebo (a substance that looks similar to the study drug but contains no active study medication).
