2013: The prevalence of dementia in Europe
Alzheimer Europe estimates the number of people with dementia in Portugal in 2012 as being 182,526. This represents 1.71% of the total population of 10,699,333. The number of people with dementia as a percentage of the population is somewhat higher than the EU average of 1.55%. The following table shows the estimated number of people with dementia between 30 and 59 and for every 5-year age group thereafter.
