Advocates call for more research on Alzheimer's disease
Washington -- A new analysis of national census data released late last month projects that at current rates, the number of Americans with Alzheimer's disease will grow by 350% by mid-century -- even higher in states with large numbers of baby boomers. Four million Americans have the disease today, but that will grow to 8 million by 2030 and 14 million by 2050.
After age 65, one in every 10 Americans has the disease, but after age 85 half do.
The only way to avoid the epidemic is to accelerate the search for a way to delay, prevent or cure the disease, research scientists say. Brain cells begin to change at least 10 years before the symptoms of Alzheimer's appear, said Steven DeKosky, MD, chair of the Alzheimer's Assn.'s Medical and Scientific Advisory Council. "We do not have enough time left to do [traditional, lengthy] five-year trials one at a time," he said. "Scientists have many more good ideas for effective treatments than they can test with current funding."
