(Medical Xpress)—A limited time window to administer therapy for ischemic stroke means every second counts. Now doctors may be able to slow down the hands of time in this critical time frame by using hypothermia - cooling the body to halt reperfusion injury of brain tissue. http://medicalxpress.com/news/2013-02-cooling-treatment-acute-ischemic-preliminary.html Cardiology Thu, 21 Feb 2013 08:50:01 EST news280657922 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 critical question shortly after a brain cancer patient starts treatment: how well is it working?

Their study is published in the current issue of Cell Transplantation (21:6), now freely available on-line. http://medicalxpress.com/news/2012-10-therapeutic-window-important-factor-cord.html Medical research Mon, 01 Oct 2012 12:01:59 EST news268311707 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 A new class of drug developed at Northwestern University Feinberg School of Medicine shows early promise of being a one-size-fits-all therapy for Alzheimer's disease, Parkinson's disease, multiple sclerosis and traumatic brain injury by reducing inflammation in the brain. http://medicalxpress.com/news/2012-07-drug-alzheimer-multiple-sclerosis-brain.html Neuroscience Tue, 24 Jul 2012 17:09:11 EST news262368535 Activity lingers longer in certain areas of the brain in those with Alzheimer's than it does in healthy people, Mayo Clinic researchers who created a map of the brain found. The results suggest varying brain activity may reduce the risk of Alzheimer's disease. The study, "Non-stationarity in the "Resting Brain's" Modular Architecture," was presented at the Alzheimer's Association International Conference and recently published in the journal PLoS One. http://medicalxpress.com/news/2012-07-mayo-clinic-brain-alzheimer-patients.html Alzheimer's disease & dementia Mon, 16 Jul 2012 11:34:06 EST news261657235 (HealthDay) -- The costs of the obesity epidemic to the United States and the economic value of curbing it are not captured fully by current methods, according to a new report. http://medicalxpress.com/news/2012-03-underestimates-long-term-obesity-experts.html Health Wed, 21 Mar 2012 16:11:24 EST news251564960 Thromboembolic stroke, caused by a blood clot in the brain, results in damage to the parts of the brain starved of oxygen. Breaking up the clot with tissue plasminogen activator (tPA) reduces the amount of damage, however, there is a very short time window when the value of the treatment outweighs the side effects. New research published in BioMed Central's open access journal Experimental & Translational Stroke Medicine shows that, during the first 24 hours after a stroke, mild hypothermia (34C) can reduce the side effects of tPA and potentially increase the window of opportunity for tPA treatment. http://medicalxpress.com/news/2012-03-hypothermia-brain.html Neuroscience Tue, 06 Mar 2012 19:00:02 EST news250274756 When a motor nerve is severely damaged, people rarely recover full muscle strength and function. Neuroscientists from Children's Hospital Boston, combining patient data with observations in a mouse model, now show why. It's not that motor nerve fibers don't regrow -- they can -- but they don't grow fast enough. By the time they get to the muscle fibers, they can no longer communicate with them. http://medicalxpress.com/news/2011-10-reversing-motor-nerve-essence.html Medical research Mon, 03 Oct 2011 12:00:05 EST news236861754
