African-Americans know the signs of stroke, but concerns about medical cost, ambulance response time and unfamiliarity with the need for prompt hospital care impacted whether they called 9-1-1 immediately. http://medicalxpress.com/news/2013-05-impacts-african-americans-immediately.html Cardiology Tue, 14 May 2013 16:00:03 EST news287758285 Millions of Americans take aspirin or other drugs every day to reduce their risk of heart attacks or other problems caused by blood clots. http://medicalxpress.com/news/2013-03-blood-thinners-treatment-danger.html Cardiology Wed, 13 Mar 2013 10:10:33 EST news282388225 Every 30-minute delay in breaking up a blood clot from a stroke was associated with a 10 percent decrease in the probability of a good outcome, regardless of other factors such as stroke severity, according to late-breaking research presented at the American Stroke Association's International Stroke Conference 2013. http://medicalxpress.com/news/2013-02-blood-clots-worse-outcome.html Cardiology Mon, 11 Feb 2013 06:20:01 EST news279785415 Adding endovascular therapy to clot-busting therapy for stroke did not significantly improve stroke recovery at three months, according to a study presented in a special symposium at the American Stroke Association's International Stroke Conference 2013. http://medicalxpress.com/news/2013-02-adding-endovascular-therapy-tpa-didnt.html Cardiology Fri, 08 Feb 2013 05:50:01 EST news279524104 The first outcome-based guidelines for interventional treatment of acute ischemic stroke—providing recommendations for rapid treatment—will benefit individuals suffering from brain attacks, often caused by artery-blocking blood clots. Representatives from the Society of Interventional Radiology and seven other medical societies created a multispecialty and international consensus on the metrics and benchmarks for processes of care and technical and clinical outcomes for stroke patients. http://medicalxpress.com/news/2013-01-medical-societies-patient-centered-nonsurgical-interventions.html Cardiology Tue, 29 Jan 2013 10:02:54 EST news278676108 A new survey of stroke survivors has shown that those with post-traumatic stress disorder (PTSD) are less likely to adhere to treatment regimens that reduce the risk of an additional stroke. Researchers found that 65 percent of stroke survivors with PTSD failed to adhere to treatment, compared with 33 percent of those without PTSD. The survey also suggests that nonadherence in PTSD patients is partly explained by increased ambivalence toward medication. Among stroke survivors with PTSD, approximately one in three (38 percent) had concerns about their medications. Results of the study, led by Columbia University Medical Center researchers, are published today in the British Journal of Health Psychology. http://medicalxpress.com/news/2013-01-survivors-ptsd-treatment.html Psychology & Psychiatry Fri, 18 Jan 2013 00:00:01 EST news277661759 Telestroke networks that enable the remote and rapid diagnosis and treatment of stroke can improve the bottom line of patients and hospitals, researchers report. http://medicalxpress.com/news/2012-12-telestroke-networks-cost-effective-hospitals-good.html Cardiology Mon, 17 Dec 2012 11:00:58 EST news274964445 A small molecule known to regulate white blood cells has a surprising second role in protecting brain cells from the deleterious effects of stroke, Johns Hopkins researchers report. The molecule, microRNA-223, affects how cells respond to the temporary loss of blood supply brought on by stroke—and thus the cells' likelihood of suffering permanent damage. http://medicalxpress.com/news/2012-11-duty-immune-brain-effects.html Immunology Wed, 28 Nov 2012 14:48:07 EST news273336473 A process developed to increase efficiency and productivity in Japanese car factories has helped improve stroke treatment at Barnes-Jewish Hospital, report researchers at Washington University School of Medicine in St. Louis. http://medicalxpress.com/news/2012-10-patients-benefit-carmaker-efficiency.html Cardiology Thu, 18 Oct 2012 16:00:07 EST news269786421 Researchers at the University of Geneva (UNIGE), in collaboration with UK company Proteome Sciences plc (PS) describe a simple blood test that could substantially increase the number of patients eligible for highly effective ischaemic stroke therapy in a paper "Blood Glutathione S-Transferase-pi (GSTP) as a Time Indicator of Stroke Onset", published last week in the journal PLoS ONE. http://medicalxpress.com/news/2012-09-blood-effective-treatment-five-fold.html Cardiology Thu, 20 Sep 2012 06:22:44 EST news267340957 Investigators at the Stanford University School of Medicine have shown that removing a matched set of molecules that typically help to regulate the brain's capacity for forming and eliminating connections between nerve cells could substantially aid recovery from stroke even days after the event. In experiments with mice, the scientists demonstrated that when these molecules are not present, the mice's ability to recover from induced strokes improved significantly. http://medicalxpress.com/news/2012-03-drug-recovery.html Neuroscience Wed, 21 Mar 2012 13:15:33 EST news251554444 Scientists at the Toronto Western Research Institute (TWRI), Krembil Neuroscience Center, have developed a drug that protects the brain against the damaging effects of a stroke in a lab setting. This drug has been in development for a few years. At this point, it has reached the most advanced stage of development among drugs created to reduce the brain's vulnerability to stroke damage (termed a "neuroprotectant"). Over 1000 attempts to develop such drugs by scientists worldwide have failed to be translated to a stage where they can be used in humans, leaving a major unmet need for stroke treatment. The drug developed by the TWRI team is the first to achieve a neuroprotective effect in the complex brain of primates, in settings that simulate those of human strokes. ischemic stroke. http://medicalxpress.com/news/2012-02-scientists-world-advanced-drug-brain.html Medical research Wed, 29 Feb 2012 13:54:13 EST news249746047 The Newcastle team who helped develop the FAST system to identify a stroke are now piloting an app to ensure the best treatment for stroke patients. http://medicalxpress.com/news/2012-02-dash-app-treatment.html Health Fri, 17 Feb 2012 11:14:37 EST news248699666 The University of Kentucky will be the first site in the state and one of a select few in the entire country participating in the first stages of a groundbreaking study to investigate the effects of MultiStem, a human adult stem cell product, on patients with acute ischemic stroke.

A study led by Raymond A. Swanson, MD, chief of the neurology and rehabilitation service at the San Francisco VA Medical Center, provides a possible reason: high blood sugar fuels the formation of superoxide, a toxic form of oxygen, which in turn damages tissues, weakens blood vessels and promotes excess bleeding. http://medicalxpress.com/news/2011-10-clue-brain-treatment.html Neuroscience Mon, 17 Oct 2011 09:26:22 EST news238062360 Stroke patients who need emergency care should be taken to the nearest certified primary stroke center, which acts as a central point for stroke treatment, according to recommendations from the Brain Attack Coalition (BAC), a group representing medical, scientific, nonprofit and government leaders in the field of stroke. The recommendations, which reflect advances in stroke treatment over the past decade, are published online in the September issue of the journal Stroke. http://medicalxpress.com/news/2011-08-brain-coalition-primary-centers.html Cardiology Fri, 26 Aug 2011 09:58:40 EST news233571506 African-Americans are less likely than whites to receive critical stroke treatment primarily because they do not get to a hospital soon enough for time-sensitive treatment and because of preexisting medical conditions.
