Dementia prevalence will continue to grow over the next 20 years,
with the oldest groups becoming increasingly important

Dementia_prevalence‌ ‌

Ageing societies present new challenges, such as the rising prevalence of age-related conditions like dementia. The likelihood of having dementia is strongly correlated with age. Dementia remains relatively rare in working age adults, with between 2% and 10% of cases starting before the age of 65 (World Health Organization, 2012a). However, after the age of 80, prevalence increases steeply and nearly half of all Europeans over the age of 95 have dementia.

Ageing populations therefore mean more cases of dementia. If age-specific prevalence rates are assumed to remain constant, demographic change has led to a 50% increase in overall prevalence in Europe over the last 20 years and we should expect a similar increase in the next 20 years. There will be a particularly rapid increase in the number of people over 95 with dementia.

Source: OECD analysis of data from Alzheimer's Europe and the United Nations; assumes age-specific prevalence rates are constant over time.
