...that when people who are at highest risk of Alzheimer's try to recognize a famous name, their brains activate in very different ways from those of people who aren't at risk. And scientists can actually see this difference using functional magnetic resonance imaging, or fMRI. (Read "Gingko Biloba Does Not Prevent Alzheimer...
...currently only two types of drugs have received government approval in the U.S. to slow the progression of Alzheimer's, but both offer only limited benefits - and many caregivers, desperate to better the lives of their patients, resort to such low-tech, behavior-based solutions as singing.

Reporting Nov. 18 in the Journal of the American Medical Association, Dr. Steven DeKosky, dean of the school of medicine at University of Virginia, found that taking 120 mg of gingko biloba twice a day did not prevent the development of dementia in a group of 1,545 seniors 75 years and older; there was no difference in rates of dementia among the intervention group and a similar group of 1,524 participants who took identical placebos. This was the largest and longest investigation into the effects of gingko biloba, and the first study to explore whether a supplement could...
DeKosky, who was at the University of Pittsburgh between 2000 and 2008, when the trial was conducted, decided to address the uncertainties by designing a randomized, controlled, double-blinded trial - the most rigorous study of gingko biloba to date. The end result is scientific confidence that the findings are both reliable and reproducible: At the end of six years of follow up, 523 of the more than 3,000 healthy subjects had developed dementia - 277 of those patients had taken gingko, and 246 had received the placebo. Of these cases, 92% were likely in the first phase of Alzheimer...
