Summary
Research in the United States indicates that the proportion of elderly people (aged over 65) with dementia has declined from 11.6% in 2000 to 8.8% in 2012.
Previously expected future growth rates for the burden of dementia may not be as dramatic as projected earlier, possibly due to higher levels of education and improved physical health in the population at large.
