Filter by:Noninvasive brain stimulations (NIBS) will be used in chronic stroke patients to improve motor learning. Functional magnetic resonance imaging will be used to evaluate the mechanisms underlying motor learning in healthy volunteers and in chronic stroke patients.
The purpose of this study is to evaluate the safety and efficacy of autologous peripheral hematopoietic stem cell transplantation in ischemic stroke.
Stroke is the leading cause of disability worldwide and the leading cause of death in Brazil. It is estimated that about 18 million people will have a stroke in 2015 and approximately one third of these resulting in death. The factors most important modifiable risk for stroke include high blood pressure (hypertension), diabetes, smoking, dyslipidemia, sedentary lifestyle and obesity. Acting on these risk factors can be reduced by 88% the risk of another stroke. Healthy eating is among the changes in lifestyle that are recommended for prevention and treatment of one of the main risk factors for stroke. Studies show that the adoption of the DASH diet can significantly reduce blood pressure and the result is even more significant in hypertensive patients, making this diet a new alternative in the prevention and treatment of hypertension and consequently stroke. Compliance therapy is a determining factor for success in the treatment of chronic diseases. Adherence to long-term treatment in developed countries is around 50% and in developing countries the rates are even lower. The aim of this study is to evaluate the effectiveness of nutritional counseling in an adapted DASH style diet on body weight, glycemic control, blood pressure values and improved lipid profile compared to the usual diet without nutritional counseling in patients with stroke within the last 3 months. The hypothesis is that nutritional counseling with an adapted DASH style diet reduces cardiovascular risk factors compared with the usual diet without nutritional counseling in patients with stroke within 3 months. The stroke patients will be selected in the hospitalization or in the outpatient clinic of Hospital de Clínicas de Porto Alegre in a period up to 3 months after ischemic stroke. The patients will be randomized to one of the 2 groups. In the first visit they will be submitted to a social class and international physical activity questionnaire and they will be submitted to a food frequency questionnaire, measures of weight, height, waist circumference, hip and neck, blood pressure and cholesterol and glucose measurements at the baseline, 30 days and 3, 6, 9 and 12 months. The main endpoints will be the change in the body weight, blood glucose, blood pressure values and lipid profile.
In this study the investigators will examine the efficacy of navigated excitatory repetitive transcranial magnetic stimulation (nerTMS) for the treatment of post stroke aphasia. The investigators expect that this new types of rehabilitation (nerTMS) will help patients with aphasia return to their lives as they were prior to the stroke.
The purpose of this study is to examine the effects of a combination of "Botulinum Toxin (BT) and Upper Limb (UL) rehabilitation" compared to "BT only" on UL motor function in adults with spasticity after stroke using a pre-post design. The research question is whether combination of BT and UL rehabilitation compared to BT only is more effective in improving the UL function, range of motion and pain.
The investigators would like to conduct a double blind placebo-controlled prospective study to show the impact of a treatment combining a specific cognitive rehabilitation program and acetylcholinesterase inhibitors on executive function of young patients 3 months after a first symptomatic stroke. The secondary objectives will be to assess cognitive changes performance (executive but also non trained functions such as memory) before and after treatments and treatment effect on activity of daily living and on quality of life. The main objective of this study is to show the impact of this combined treatment on brain activation maps in VCI-ND patients in the post-acute phase (3 months) after a stroke. Treatment effect will be assessed by functional MRI (fMRI) while patients will be performing a specific executive task. The investigators hypothesize that the specific rehabilitation associated with acetylcholinestrase inhibitors treatment will focalize cerebral activation observed in fMRI, improve executive functions specifically, improve non trained cognitive functions (generalization effect).
The experience of a stroke event may result in a disruption to the survivor's daily life. Patients with stroke have reported fears of permanent disability and major concerns over their ability to recover and be productive and engaged with family, friends and coworkers. To enhance recovery from stroke, the investigators designed a stroke self-management program and have pilot tested the program among Veterans recovering from stroke/TIA. The study is a three-site, randomized controlled trial designed to test the efficacy of a stroke self-management program. The intervention program includes 6 bi-weekly sessions over months 1-3 followed by monthly telephone calls as the investigators administered in the investigators' pilot study during months 4-6 for a total length of program duration of 6 months. The investigators have added 3 monthly group support sessions during months 4-6 for additional peer support. Thus, participants will receive bi-monthly support during months 4-6. The three intervention sites include the Jesse Brown VAMC in Chicago, the Roudebush VAMC in Indianapolis, and the IU Health Methodist Hospital in Indianapolis, Indiana. The three hospitals represent facilities with a small, moderate, and large volume of acute stroke care, respectively. Additionally, Methodist Hospital includes a greater proportion of women which enables us to study the patterns and preferences of women with stroke/TIA and tailor the investigators' future programs to prepare for the increasing female Veteran population.
Noninvasive brain stimulations will be used in acute and chronic stroke patients to improve a variety of functions.
Stroke is the second leading cause of death and the leading cause of adult disability worldwide. This investigation will address the safety and feasibility of directed, intra-arterial Magnesium measurement and therapy, through endovascular access, in acute stroke patients. The proposal represents the first study to directly quantify levels of a systemically administered neuroprotectant in the region of cerebral ischemia. It also establishes a novel endovascular platform for direct delivery of neuroprotective agents to ischemic cerebral tissue distal to an occlusive thrombus. This research seeks to improve patient care by establishing a novel delivery mechanism for the rescue of threatened brain parenchyma that can be administered rapidly following acute stroke. If successful, this selective distribution will allow delivery to "at risk" tissue in a rapid manner. Salvage of viable, but threatened, penumbral tissue could afford stroke patients an increased probability of favorable long term outcome. The investigators hypothesize that endovascular, intra-arterial, Magnesium administration will deliver high concentration of this neuroprotective agent to otherwise inaccessible cerebral territories, while limiting systemic concentrations. The proposed investigation will evaluate the safety and feasibility of this novel treatment technique
This investigation will address the safety and feasibility of distal, intra-arterial sampling through endovascular access, in acute stroke patients. Levels of Magnesium will be measured in the region of infarct in patients who had been treated with intravenous Magnesium therapy following an acute stroke. This study attempts to address whether the traditional intravenous means of neuroprotectant administration achieves adequate concentration of the therapeutic agent in the area of diseased tissue.
