Stroke is the sudden onset of a neurological impairment, sometimes of crippling intensity. It is usually caused by occlusion of an artery that supplies the brain or spontaneous bleeding in the brain.
Stroke Community Forum
Support for patients with stroke, its warning signs, risk factors, prevention, complications. Discussions among patients, families, caregivers and professionals on topics related to diagnosis, treatment, and activities of daily living.
Applying new cholesterol guidelines to a patient population reduces heart attacks, strokes
Aug 19, 2014
A study by UT Southwestern researchers identified Dallas Heart Study participants in the 30- to 65-year rage range who would have newly qualified for statin use under the cholesterol guidelines introduced in 2013 by the American College of Cardiology and the American Heart Association. They found that the recently introduced cholesterol guidelines would significantly reduce new cardiovascular events when compared to treatment based on previous cholesterol guidelines.
Experiencing atrial fibrillation while hospitalized for surgery linked with increased risk of stroke
Aug 13, 2014
In a study that included 1.7 million patients undergoing inpatient surgery, experiencing atrial fibrillation while hospitalized was associated with an increased long-term risk of ischemic stroke, especially following noncardiac surgery, according to a study in the August 13 issue of JAMA.
Monitoring pulse after stroke may prevent a second stroke
Jul 24, 2014
New research suggests that regularly monitoring your pulse after a stroke or the pulse of a loved one who has experienced a stroke may be a simple and effective first step in detecting irregular heartbeat, a major cause of having a second stroke. The study is published in Neurology®.
Incidence of stroke in the elderly has dropped by 40% over the last 20 years
Jul 18, 2014
A new analysis of data from 1988-2008 has revealed a 40% decrease in the incidence of stroke in Medicare patients 65 years of age and older. This decline is greater than anticipated considering this population's risk factors for stroke, and applies to both ischemic and hemorrhagic strokes. Their findings are published in the July issue of The American Journal of Medicine.
Electrical stimulation of fastigial nucleus and cellular apoptosis in injured region
Jul 08, 2014
Previous studies have indicated that electrical stimulation of the cerebellar fastigial nucleus in rats may reduce brain infarct size, increase the expression of Ku70 in cerebral ischemia/reperfusion region, and decrease the number of apoptotic neurons. A new study finds anti-apoptotic activity of Ku70 in cytoplasm of rats subjected to electrical stimulation of cerebellar fastigial nucleus is related to colocalization of Ku70 with Bax.
Blocking key enzyme minimizes stroke injury
Jun 26, 2014
A drug that blocks the action of the enzyme Cdk5 could substantially reduce brain damage if administered shortly after a stroke, UT Southwestern Medical Center research suggests. The findings, reported in the June 11 issue of the Journal of Neuroscience, determined in rodent models that aberrant Cdk5 activity causes nerve cell death during stroke.
Migrating stem cells possible new focus for stroke treatment
May 27, 2014
A research group at Lund University in Sweden has revealed that stem cells known as pericytes, which are located in the outer blood vessel wall, appear to be involved in the brain reaction following a stroke. The findings show that the cells drop out from the blood vessel, proliferate, and migrate to the damaged brain area where they are converted into microglia cells, the brain's inflammatory cells.
Predicting which stroke patients will be helped—or harmed—by clot-busting treatment
May 20, 2014
Johns Hopkins researchers say they have developed a technique, which uses standard MRI scans to measure damage to the blood-brain barrier, that can predict—with 95% accuracy—which stroke victims will benefit from intravenous, clot-busting drugs and which will suffer dangerous and potentially lethal bleeding in the brain.
