Filter by:Stroke is the leading cause of adult disability and the third leading cause of death in Canada. Most stroke survivors live with residual impairments that diminish independence and quality of life. This may include vascular cognitive impairment (loss of ability to plan, think and reason) which can lead to dementia and loss of mental and functional independence. The current treatment to reduce stroke induced brain tissue injury is limited to thrombolytics (clot busters), a therapy useful only if given in the first hours following stroke. One major new approach aims to reduce cell death after stroke by targeting the ongoing tissue loss initiated by the stroke. The tissue can be maintained by interfering with later neurochemical processes that are activated by stroke, potentially through activating natural substances in the brain that help survival and growth of nerve cells ("neurotrophic" factors). The recent recognition of lithium as a neurotrophic agent has generated the first studies of lithium treatment for managing brain diseases. Clinically, lithium has now been shown to increase brain gray matter volume in bipolar patients. This effect is potentially important in stroke because gray matter loss has been implicated in the development of cognitive impairment after stroke, a result of the series of brain processes that are activated by lack of oxygen due to stroke. Our primary objective is to examine the effects of lithium on total brain gray matter volume in the post-stroke population, as measured by volumetric magnetic resonance imaging (MRI) with the hope that lithium may increase gray matter volume in post-stroke patients and lead to greater cognitive and functional rehabilitation. This study will provide valuable information on the tolerability of lithium, and its effects on clinical outcomes relevant to stroke, providing the information needed for designing a large-scale clinical trial.
Currently there is a lot of literatures on stroke rehabilitation and post-discharge therapy. However, there are few evidence based guidelines on patient engagement after stroke in the post-rehabilitation community phase. There is evidence from stroke studies that stroke patients with mild to moderate disability, discharged early from an acute hospital unit can be rehabilitated in the community by an interdisciplinary stroke rehabilitation team and attain similar functional outcomes when compared to patients receiving in-patient rehabilitation. There is strong evidence that additional hospital based outpatient therapy improves short term functional outcomes compared to routine care over short term. Although meta-analyses have examined the efficacy of self management education programs, the interpretation of such reviews is limited by heterogeneity in populations and interventions and the limited range of outcomes measured. Few randomized controlled trials have found a reduction in health service utilization, such as incidences of hospitalization (in patients with chronic lung disease, heart disease, stroke and arthritis) as a direct outcome of attending an education program. For self-management support to be effective and sustainable in the community, it is postulated that initiatives simultaneously focus on supporting patients to engage in self management and equipping health care professionals with the necessary resources to assist them.
Aim of this randomized controlled study is to test if intensive polyintervention therapy including life style modifications targeting at reduction of modifiable risk factors of stroke can reduce the risk of post-stroke cognitive decline compared to a group of patients receiving standard care.
Approximately 780,000 people suffer a stroke annually in the United States; 200,000 are recurrent strokes. The 17,000 veterans who suffer a stroke yearly are at great risk for a second stroke and therefore should be targeted for stroke risk factor management and prevention interventions. Balance and fear of falling negatively impact activity and function. Decreased activity and blood pressure (BP) are important modifiable stroke risk factors. These can be addressed through a yoga exercise intervention. Yoga, like tai-chi, is old world alternative medicine that has the potential to greatly impact the lives of older adults.
Intrathoracic positive pressure may lead to a change hemodynamics, with repercussions for the intracranial compartment, thereby altering intracranial pressure (ICP) and cerebral perfusion pressure (CPP). This effect may become more intense when using high positive end expiratory pressure (PEEP) values. The aim of the present study was to measure the impact of different PEEP values on ICP, CPP and mean arterial pressure (MAP). MAP, whereas high PEEP values increase ICP, although without clinical relevance.
In Western Countries, stroke and dementia are the main causes of long-term disability, dependency, and nursing home admission. Due to demographic trends a continuous increase of patient numbers can be expected. There is growing evidence that vascular risk factors which are implicated in the etiology of stroke also play important etiologic roles in both vascular dementia and Alzheimer disease. The present project is aimed at the reduction of stroke and dementia by means of a systematic detection and subsequent treatment of vascular risk factors by the family doctor based on established guidelines.
This study aims to examine the evolution and determinants of physical fitness after stroke.
The aim of this study was to investigate the effects of gait training on ground level, combining BWS and FES in people following chronic stroke.
The aim of this study is to identify patients with problem list gaps and intervene to correct these gaps by creating clinical decision support interventions that alert providers to likely problem list gaps and offer clinicians the opportunity to correct them. The investigators will randomize the clinics that will receive the intervention and formally evaluate the study after a period of 6 months for improved problem list completeness to determine the effectiveness of our intervention.
The purpose of the study is to evaluate whether desmoteplase is safe and tolerated when given to Japanese patients with acute ischemic stroke
