A perplexing medical paradox now has an explanation according to research undertaken at Barts and The London School of Medicine and Dentistry and published in the current issue of the Public Library of Science ONE. The paradox is that taking folic acid, a B vitamin, lowers homocysteine in the blood which, epidemiological evidence indicates, should lower the risk of heart attack, but clinical trials of folic acid have not shown the expected benefit. http://phys.org/news215890268.html Medicine & Health Wed, 02 Feb 2011 17:31:41 EST news215890268 Researchers have identified a gene that appears to increase a person's risk of developing late-onset Alzheimer's disease, the most common type of Alzheimer's disease. The research will be presented as part of the late-breaking science program at the American Academy of Neurology's 62nd Annual Meeting in Toronto, April 10 - 17, 2010.
