Filter by:The cerebrovascular accident (CVA) is currently the leading cause of death in Brazil and it is estimated that there are about 62 million stroke survivors worldwide. Thus, the stroke sequels are a major public health problem not only in Brazil but in the world, with existing treatments often insufficient for complete recovery. Thus this study aims to identify predictors of different responses from rehabilitation therapy through the evaluation of clinical and neurophysiological data performed before and after treatment. For the neurophysiological study will be used the association of electroencephalogram (EEG) and transcranial magnetic stimulation (TMS). This last one will be performed in the baseline and after a single Transcranial direct current stimulation (tDCS) session, aiming to leverage the ability of those technics to analyze the cerebral plasticity. As a secondary objective: 1) Identify specific features of brain plasticity involved in recovery from stroke and discuss the possible implications of these findings in the therapeutic approach; 2) Search possible electrophysiological markers that can be used as surrogate outcome of stroke of motor sequel.
The WHISH trial applies state-of-the science behavioral principles and currently available technologies to deliver a physical activity intervention without face-to-face contact to ~25,000 older U.S. women expected to consent. It includes the National Institute of Aging (NIA) Go4Life® Exercise & Physical Activity materials 3 and WHISH developed targeted materials based on Go4Life® to provide inspirational tips and recommendations about how to achieve nationally recommended levels of PA and overcome barriers to exercise, with a means for self-monitoring and setting personal goals. The intervention builds upon evidence-based behavioral science principles and intervention components that have proven to be effective in increasing PA in older women, with innovative adaptive approaches to tailoring the delivery to meet individual (personal) needs.
This study evaluates a new rehabilitation approach for stroke survivors in the chronic phase of recovery in which the combination of drug therapy (cyproheptadine) and active movement practice (AMP) is used to encourage increased voluntary muscle control and strength.
Confirm central blood pressure reduction effect of Fimasartan, Valsartan and Atenolol and compare correlation with the measured peripheral (central blood pressure, pulse wave velocity, and flow-mediated dilation) and cerebral blood flow factors (transcranial doppler findings, cerebral blood flow volume) in acute ischemic stroke patients with hypertension.
This trial will enroll patients that have been diagnosed with a transient ischemic attack (TIA) or minor stroke that has occurred within the past 12 hours. Anyone diagnosed with a minor stroke faces the possibility of long-term disability and even death, regardless of treatment. Stroke symptoms such as weakness, difficulty speaking and paralysis may improve or worsen over the hours or days immediately following a stroke. TEMPO-2 is a minor stroke trial for patients presenting within 12 hours of their symptom onset. Patients will be randomized to TNK-tPA or standard of care. In the intervention group TNK-tPA is given as a single, intravenous bolus (0.25mg/Kg) immediately upon randomization. Maximum dose 50mg. The control group will receive antiplatelet agent(s) as decided by the treating physician. Antiplatelet agent(s) choice will be at the treating physician's discretion. TEMPO-2 Coordinating Centre is located in Calgary, AB, Canada. There will be approximately 50 sites participating worldwide. Dr. Shelagh Coutts is the Principal Investigator.
There is few information about the association between supraventricular arrhythmia different from atrial fibrillation (AF) or atrial Flutter and the risk of stroke. In this study the investigators hypothesized that the presence of atrial tachycardia would lead to atrial fibrillation and recurrent stroke in patients hospitalized for cryptogenic stroke. The investigators study the association of atrial tachycardia (AT), defined as four or more consecutive premature atrial beats, and AF, recurrent stroke and cardiovascular mortality in 192 consecutive patients hospitalized because of cryptogenic stroke. The follow-up was 12 months for all population
This study is being done to see if there is a relationship between stroke, post-stroke depression, and measures of inflammatory and/or stress compounds in the blood. Brain injury, as caused by stroke, leads to an inflammatory response in the brain which in turn can influence inflammatory and stress responses in other parts of the body outside of the brain. These responses can be measured by analyzing various substances in the blood and in the white blood cells. The investigators will measure these substances (cytokines, glucocorticoids) and compare them to the absence, presence, or degree of depression that the investigators will determine by neurological and psychological testing. The investigators will be drawing blood for this study on admission, at or around day 3, at or around day 7 and at or around day 90, which is not part of routine stroke care. The investigators will be asking subjects to participate in answering question/scales on these same days, some of these questionnaires are also not part of routine stroke care. Standard stroke care is being done other than blood drawing/participating in answering questions/scales. Approximately 25 people will be enrolled over one year.
The primary objective of this study is to determine whether baseline DOC screening can add to clinical and demographic data to predict the occurrence of a composite negative outcome (any of: recurrent stroke, myocardial infarction, death, or admission to a long-term care (LTC) / complex continuing care (CCC) facility) within one year of screening, in stroke prevention clinic patients.
Stroke affects over 125,000 people each year in the UK and leaves at least 50% disabled. Treatment of stroke caused by a blockage in a blood vessel (ischaemic stroke), with clotbusting drugs improves the chances of good recovery, but must be given within 4.5 hours of onset. Currently only a small proportion of patients who arrive in hospital within 4.5 hours are treated. This is largely due to uncertainty about diagnosis and concerns about risk of bleeding associated with clotbusting medication. Patients with mild or improving symptoms in particular are often not treated because of uncertainty about relative risks and benefits. However, around one third of these patients go on to be significantly disabled. Routine CT scanning often does not show abnormalities in acute stroke (which take hours to become easily visible), and cannot show the extent or severity of blood flow changes in ischemic stroke. We wish to investigate the value of additional CT scanning that gives information on the blood vessels (angiography, CTA) and blood flow to the brain (perfusion, CTP) by undertaking a randomised trial. Extra scans are done in the same scanner and involve some extra radiation, injections of a contrast dye, and some extra time to acquire process and interpret. The extra scans may allow better treatment decisions for patients by increasing diagnostic certainty and by better assessment of stroke severity. However, we do not know whether the potential gains from better selection justify the resources and potential treatment delays that are involved. We will investigate whether the proportion of patients given clotbusting drugs differs between the two scanning protocols; and whether the outcomes differ, using standard measures of disability. We will also investigate whether use of different scanner manufacturers' software affect interpretation of scans.
Anticoagulants are generally recognized as a necessary therapy to prevent the recurrence of ischemic stroke in patients with non-valvular atrial fibrillation (NVAF), but in some patients they also cause bleedings, particularly intracranial hemorrhage. One of the independent predictors of intracerebral hemorrhage is the presence of cerebral microbleeds (CMBs); a high incidence of intracerebral hemorrhage is reported in patients with multiple CMBs. Recent study suggested that patients who had CMBs at baseline developed more new CMBs after 2 years (26%), compared with patients (12%) who did not have CMBs at baseline. However, there has been no study on the progression of CMBs in patients receiving so-called novel oral anticoagulants (NOACs). This study tests the hypothesis that the incidence of hemorrhagic stroke is lower in patients receiving NOACs (dabigatran, rivaroxaban, apixaban, and edoxaban) than in those receiving warfarin, and this difference reflects the difference in the effects of warfarin and NOACs on the progression of CMBs. Towards this goal, we enroll 200 patients with at least one CMB detected by 1.5 T MRI (T2*WI) at baseline, who treated with NOACs or warfarin for 12 months. Primary endpoint is the proportion of subjects with an increased number of CMBs at Month 12 of treatment with NOACs or warfarin. If the results of this study support the efficacy of NOACs in preventing increase of CMBs, this would be of great interest to domestic and overseas clinicians, in view of the potential therapeutic impact, including that for primary prevention of ischemic stroke.
