Filter by:A stroke is a sudden loss of brain function. It is caused by the interruption of flow of blood to the brain (ischemic stroke) or the rupture of blood vessels in the brain (hemorrhagic stroke). This study will investigate the use of far infrared radiation for stroke rehabilitation.
Two large homocysteine-lowering B-vitamin intervention trials have been performed in Norway during the period 1998 to 2005, NORVIT and WENBIT. The main objective in these trials was to study the clinical effects of homocysteine-lowering therapy with folic acid and vitamin B12 in patients with established coronary artery disease. Follow-up was terminated for NORVIT on Marc 31st 2004 and for WENBIT October 5th 2005, and none of the two trials proved any protective effect of the B-vitamin intervention on cardiovascular outcomes. There is so far no data on possible long-term effects following years of such B-vitamin treatment. Thus, the main objective of the combinded NORVIT-WENBIT study will will be to evaluate the long-term effect of the B-vitamin intervention on incident life-style diseases including cardiovascular disease, diabetes, osteoporotic fractures and cancer. A secondary object will be the identification of risk phenotypes or genotypes, and if such risk associations are midified by the B-vitamin intervention
The main purpose of this study is to look for genetic and environmental risk factors of cervical artery dissections, a major cause of ischemic stroke in young adults, in a large multicenter case-control trial
Our primary goal is to study temporal trends in the incidence rate, causes, treatment, and outcome of stroke among a large biracial metropolitan population of 1,349,351, of whom 215,611 (15%) are black (2000 Census). Such data are critical for the planning, intervention, and evaluation of public health efforts to decrease the mortality and morbidity due to stroke in the United States. We have completed this goal for 1993-94, 1999, 2005, 2010 and 2015. We are in the process of collecting this data for 2020. In the 2020 study period we will also be ascertaining 3 year recurrence rates for all incident stroke events.
This study examines the hypothesis that 6 months of treadmill aerobic exercise training improves fibrinolysis (clot defense mechanism) and vasomotor function in chronic hemiparetic (muscular weakness or partial paralysis restricted to one side of the body) stroke patients compared to a control intervention, and that these changes are associated with reduced plasma insulin levels and improved insulin sensitivity / glucose metabolism in this population.
The aim of the study is to evaluate the effect of a group intervention programme for community dwelling elders with stroke or TIA.The intervention is inspired by a Lifestyle Redesign method developed in the USA. The study is conducted as a multi centre randomized controlled trial. Participants are recruited from five hospitals and the intervention is implemented at six to seven senior centres. The control group is offered physical activity at the senior centre once a week. The intervention group is offered the same with addition of the programme inspired by Lifestyle Redesign. The study will contribute to knowledge whether the intervention will promote social participation and thriving in daily life and prevent social isolation and depressive symptoms among community dwelling elders with stroke or TIA.
Medications for memory improvement are available but they may not actually improve the ability to do real world tasks. The purpose of this research study is to determine if a medicine used to treat memory problems donepezil(Aricept) enhances the ability to remember steps of functional tasks and the actual ability to perform tasks relevant to real-life independence. Aricept is an FDA approved medication for the treatment of Alzheimer's disease. Aricept is an investigational drug for the purposes of this study, and is not approved for this purpose.
The purpose of the study is to determine the effectiveness and safety of LMWH postoperative bridging therapy (standard of care) versus postoperative placebo bridging therapy (experimental arm)for patients with mechanical heart valves or atrial fibrillation or atrial flutter who are at high risk for stroke when warfarin is temporarily interrupted for a procedure.
Once discharged from hospital many stroke survivors deteriorate medically, physically and in their mobility function and many report their level of function and quality of life to be poor 12 months after inpatient rehabilitation. There is an identified need for follow-up examinations of community dwelling stroke survivors to monitor changes in function and it has been suggested that maintenance therapy could curtail declines in function. The purpose of this trial is to determine whether brief periods of intense client-centered rehabilitation therapy (tune-ups) provided at 6 month intervals can alter the natural progression of impairment (physical capacity), function and community reintegration following stroke.
The purpose of this research study is to learn how people distribute their visual attention when looking at objects nearby versus far away, and why vision may become distracted at near versus far distances.
