Combination therapies to tackle multiple changes in the brain may be needed to combat the growing problem of dementia in ageing societies, according to a study published this week in the open access journal PLoS Medicine. The study shows that multiple abnormal processes in the brain are often involved in cases of dementia, and that the drugs currently in development to treat individual brain pathologies may have a limited impact on the overall burden of dementia in the population. http://www.physorg.com/news177058872.html Medicine & Health Tue, 10 Nov 2009 07:50:02 EST news177058872 While minimally invasive coil treatments for those with a ruptured brain aneurysm have proved to be a more effective technique than traditional surgical operation in selected patients, the superior procedure is drastically more expensive, according to new research from the Zeenat Qureshi Stroke Research Center at University of Minnesota Medical School. http://www.physorg.com/news162822050.html Medicine & Health Fri, 29 May 2009 13:21:16 EST news162822050 In "talk and die" syndrome, people can have what seems to be a mild blow to the head appear perfectly lucid and then within hours lapse into a coma -- which is what reportedly happened to actress Natasha Richardson after she fell on a Canadian ski slope Monday. http://www.physorg.com/news156714302.html Medicine & Health Thu, 19 Mar 2009 20:46:08 EST news156714302 A University of Pennsylvania team has completed the first successful demonstration of a noninvasive optical device to monitor cerebral blood flow in patients with acute stroke, a leading cause of disability and death. http://www.physorg.com/news155227588.html Medicine & Health Mon, 02 Mar 2009 14:47:23 EST news155227588 In Alzheimer's disease the brain accumulates a molecule called A-beta that can be quite toxic to brain cells. Many researchers believe that finding ways to clear A-beta may be a key to treatment or prevention of Alzheimer's disease. http://www.physorg.com/news153992637.html Medicine & Health Mon, 16 Feb 2009 07:48:57 EST news153992637 Cocoa flavanols, the unique compounds found naturally in cocoa, may increase blood flow to the brain, according to new research published in the Neuropsychiatric Disease and Treatment journal. The researchers suggest that long-term improvements in brain blood flow could impact cognitive behavior, offering future potential for debilitating brain conditions including dementia and stroke. http://www.physorg.com/news138263930.html Medicine & Health Mon, 18 Aug 2008 07:38:50 EST news138263930
