Increasing prevalence of dementia among very old people
Background : it is unknown whether the age-specific prevalence of dementia among the very old changes over time. Methods : this study compares the prevalence of dementia in two population-based cross-sectional samples of very old people in northern Sweden in 2000–02 and in 2005–07. In total, 430 ind...

In total, 430 individuals aged 85 and older (mean age 89.5 years, 71.4% women) were evaluated for dementia in the first cross-section and 465 individuals (mean age 90.2 years, 70.9% women) in the second.
