Stroke

A stroke is the rapid loss of brain function(s) due to disturbance in the blood supply to the brain. This can be due to ischemia (lack of blood flow) caused by blockage, or a hemorrhage. As a result, the affected area of the brain cannot function, which might result in an inability to move one or more limbs on one side of the body, inability to understand or formulate speech, or an inability to see one side of the visual field.
Stroke Stories
  • Researchers discover substance that reinforces the brain’s self-healing functions after a stroke

    The opportunities to treat a stroke have long been limited to the hours after an attack. The loss of brain function caused by the stroke has previously been regarded as permanent. Brain researchers at Lund University have now discovered a substance that opens up the possibility of treatment up to two days after a stroke.
  • Increasing triglyceride levels linked to greater stroke risk

    A study by researchers in Denmark revealed that increasing levels of non-fasting triglycerides are associated with an increased risk of ischemic stroke in men and women. Higher cholesterol levels were associated with greater stroke risk in men only.
  • Stroke medicines still unaffordable for some survivors, according to University of Michigan research

    Young, uninsured stroke survivors or those covered by the Medicare Part D drug benefit often can't afford medications — increasing the risk for future strokes or other cardiovascular disease-related events, according to research presented at the American Stroke Association's International Stroke Conference 2011.
  • University Hospitals system-approach to stroke care increases the use of tPA therapy by 13.5-fold

    University Hospitals (UH) Stroke and Cerebrovascular Center recently reported that it has increased the use of tPA or "clot busting therapy" for ischemic stroke by 13.5 times throughout UH system hospitals since implementing the System Stroke Program (SSP). Launched in 2008, SSP sought to increase access to the lifesaving treatment for acute (urgent) ischemic stroke patients in the 15 counties surrounding Cleveland.
  • New online tool predicts probability of death from stroke

    Researchers at St. Michael's Hospital and the Institute for Clinical and Evaluative Sciences (ICES) in Toronto have developed a new tool that will help doctors predict the probability of death in patients after an ischemic stroke.
  • Hope for stroke victims

    Much of the devastation of stroke and head trauma is due to damage caused the overproduction of a substance in the brain called glutamate.
  • Study shows delayed-enhancement MRI may predict, prevent strokes

    Researchers at the University of Utah's Comprehensive Arrhythmia and Research Management (CARMA) Center have found that delayed-enhancement magnetic resonance imaging (DE-MRI) holds promise for predicting the risks of strokes, the third leading cause of death in the U.S.
  • After stroke, admission to designated stroke centers linked to decreased risk of death

    Patients who had an ischemic stroke and were admitted to hospitals designated as primary stroke centers had a modestly lower risk of death at 30 days, compared to patients who were admitted to non-designated hospitals, according to a study in the January 26 issue of JAMA.
  • Culprit found for increased stroke injury with diabetes

    Strokes are a leading cause of mortality and adult disability. Those that involve intracerebral hemorrhage (bleeding in the brain) are especially deadly, and there are no effective treatments to control such bleeding.
  • New measures could improve quality of care at stroke centers

    The American Heart Association/American Stroke Association has proposed metrics that healthcare professionals can use to monitor the diagnosis and treatment of patients at stroke centers to help improve the quality of care stroke patients receive. The recommendations are published in a scientific statement in Stroke: Journal of the American Heart Association.
  • Neural stem cells maintain high levels of reactive oxygen species, UCLA study finds

    For years, the majority of research on reactive oxygen species (ROS) – ions or very small molecules that include free radicals – has focused on how they damage cell structure and their potential link to stroke, cardiovascular disease and other illnesses.
  • Consuming fried fish may increase risk of stroke

    Eating a Southern staple, fried fish, could be one reason people in Alabama and across the "stroke belt" states are more likely than other Americans to die of a stroke, according to a study published in the December 22, 2010, online issue of Neurology, the medical journal of the American Academy of Neurology (AAN).
