New Effort to Treat Stroke More Effectively
Just a small fraction of patients who have a stroke receive the only drug � TPA � available to treat the condition. Now doctors and scientists at the University of Rochester Medical Center have developed a potential new treatment that will reach a milestone in the next few months, when the experimental treatment is tested for the first time in people who have suffered a stroke or �brain attack.�

REGARDS Study: Stroke Symptoms Common Among General Population
As many as 18 percent of adults who have no history of stroke report having had at least one symptom of stroke, according to results of a large national study published in the October 9 issue of Archives of Internal Medicine, one of the JAMA/Archives journals. Using brain imaging to screen individuals without a history of stroke reveals that many have had an undiagnosed or silent stroke, according to background information in the article. One previous study found that 11 percent of individuals age 55 to 64, 22 percent of those ages 65 to 69 and 43 percent of those older than 85 years show evidence of stroke despite never having been diagnosed with the condition. Because awareness of stroke symptoms is low, it is possible that these individuals had symptoms but did not recognize them or that the symptoms did not reach the threshold necessary for a stroke diagnosis.

Internal body clock dictates timing of different types of stroke
The internal body clock, or circadian rhythm, seems to influence the timing of different types of stroke, suggests research published ahead of print in the Journal of Neurology Neurosurgery and Psychiatry. The research team analysed data from almost 13,000 patients who had had one of three types of stroke for the first time, diagnosed by brain scan. These patients' data had been collected on a stroke register, showing that cerebral infarction, where blood flow to brain arteries is restricted, was the most common type of stroke. The rate was 89 per 100,000 of the population.

SPARCL Trial: Atorvastatin reduces recurrent stroke risk

Wingspan Intra-Cranial Stent, Alternative to Brain Surgery?
New technologies, delivered to the brain via the bloodstream and guided by more powerful brain scans, are making it easier to clear up clogged blood vessels inside our heads, or shore up weakened ones. It�s brain surgery without the surgery, also called minimally invasive, or endovascular treatment. And according to University of Michigan Health System doctors who perform such procedures on hundreds of patients a year, it�s allowing many patients to reduce their risk of a stroke � including those who wouldn�t be able to withstand a brain operation. One of the newest options is the first device designed to help doctors open up clogged blood vessels in the brain. Called the Wingspan intracranial stent, it�s a tiny wire mesh tube that can be fed into the body through an incision in the leg, threaded up through the blood vessels in the chest and neck, and inserted into the brain.

Lower doses of clot-busting drug tissue plasminogen activator (tPA) safer for stroke patients
A Johns Hopkins study has shown that patients treated for a type of stroke caused by bleeding in the brain, or intracerebral hemorrhage, survived more often if given 1 milligram instead of the previously studied 3 milligram dose of the clot-busting drug tissue plasminogen activator (tPA). In the study, Daniel Hanley, M.D., a professor and neurologist at The Johns Hopkins University School of Medicine, demonstrated that rates of continued bleeding and subsequent death can be reduced if the tPA dosage is lowered to 1 mg.

WASID trial - Identifying patients most at-risk for a secondary stroke
Among patients who have suffered a single stroke, researchers at the University of Pennsylvania School of Medicine, along with colleagues at other institutions, have found that severe stenosis, or narrowing, of the arteries in the head represents a major risk factor for the development of a subsequent stroke. Patients with recent symptoms were also at high risk. Further, women faced a greater risk of subsequent stroke than men. Their work lays the foundation for further studies into effective therapies to prevent secondary strokes.

Measuring Risk For Recurrent Ischemic Stroke with NT-proBNP and sVCAM-1 Biomarkers
Measurement of two biomarker levels in stroke survivors may provide predictive information for recurrent ischemic stroke beyond traditional risk factors, according to a study published online today by the Archives of Neurology, one of the JAMA/Archives journals. The study will be published in the January print edition of the journal. The two biomarkers are soluble vascular cell adhesion molecule 1 (sVCAM-1) and N-terminal pro-B-type natruiretic peptide (NT-proBNP). These biomarkers along with C-reactive protein, homocysteine, renin (an enzyme from the kidneys that affects blood pressure) and lipids and lipoprotein particle concentration and size were measured in 252 participants with cerebrovascular disease, a sub-group, of the Perindopril Protection Against Recurrent Stroke Study (PROGRESS). These participants had experienced ischemic stroke during the follow-up period of the study and were matched to control patients who did not have a stroke. PROGRESS was a placebo-controlled trial of a perindopril erbumine-based, blood pressure-lowering regimen (a medication) that reduced ischemic stroke risk by 24 percent among individuals with previous stroke or transient ischemic attack. Ischemic stroke is the most common kind of stroke caused by an interruption of blood flowing to the brain.

Carotid Endarterectomy Beneficial for Stroke Prevention in Patients with Moderate to Severe Stenosis
Stroke affects more than 700,000 people in the United States per year. A blockage of a blood vessel is responsible for about 80 percent of strokes. Carotid endarterectomy is the most frequently performed operation to prevent stroke. There is scientific evidence to support its use to prevent future stroke, according to a clinical practice guideline published in the September 27, 2005 issue of Neurology, the scientific journal of the American Academy of Neurology (AAN). The guideline updates the 1990 AAN statement on carotid endarterectomy.
