Senior Health Stroke Stroke Rates Have Dropped 40% for People 65+ By article A new analysis of data from 1988-2008 by researchers at the University of California San Francisco School of Medicine has revealed a 40% decrease in the incidence of stroke in Medicare patients 65 years of age and older. The decline is greater than anticipated considering this population's risk factors for stroke. Not only that, but the drop applies to both ischemic and hemorrhagic strokes. The team also found that deaths resulting from stroke declined during the same period. The findings are published in the July 2014 issue of The American Journal of Medicine.
