ABSTRACT— Data from studies of dementia prevalence between 1945 to 1985 were analyzed statistically. Prevalence rates were found to vary as a function of methodological differences between studies. However, despite these differences, the relationship between prevalence and age was found to be consistent across studies, with rates doubling every 5.1 years. Across studies, Alzheimer's disease (AD) was found to be more common in women, with a tendency for multi‐infarct dementia (MID) to be more…

TLDR
The effect of age on the rates of dementia prevalence was pronounced, up to 90 years of age, and methodological advances were found, specially regarding the homogeneity of diagnostic criteria.

TLDR
The Canadian Study of Health and Aging is reviewed in the context of studies published between January 1986 and June 1993 that documented dementia and Alzheimer's disease prevalence, finding important variability in the definition of the functional consequences of cognitive impairment in the elderly.
A diagnostic study of dementia in a London electoral ward
Estimates of the prevalence rate of dementia in those aged over 65 and living in the community vary widely, from 0.5% to 6.3% for mild dementia, and from 1% to 7.4% for moderate or severe dementia.
The incidence of dementia
TLDR
The incidence of dementia rises exponentially up to the age of 90 years, with no sign of leveling off, and incidence is lower in East Asia than in Europe.
The prevalence of dementia in 95 year olds
TLDR
The authors determined the prevalence of dementia in 338 95-year-old persons, living in Göteborg, Sweden, and compared the result with a previously examined population sample of 85 year olds, finding the prevalence was higher in women than in men at age 95.
Prevalence of dementia in Latin America: a collaborative study of population-based cohorts
TLDR
Compared with studies from developed countries, the global prevalence of dementia in LA proved similar, although a higher prevalence in relatively young subjects was evidenced, which may be related to the association between low educational level and lower cognitive reserve, causing earlier emergence of clinical signs of dementiaIn the LA elderly population.
