Nearly half a million elderly Americans likely died from Alzheimer's disease in 2010, a figure almost six times higher than previous estimates of annual deaths, according to a new study released on Wednesday.
Alzheimer's Deaths more Common
The Centers for Disease Control and Prevention has estimated that approximately 5 million people are living with Alzheimer's disease in the United States, and that 83,000 die from the condition each year.
They analyzed data from two existing studies that followed people age 65 and older, starting at a time when they did not have Alzheimer's. The participants were tracked for an average of eight years, with annual checkups and brain donation in the case of death.
One study followed religious orders of nuns and priests and the other followed people in retirement communities and senior housing facilities. In all, the studies tracked 2,566 people.
