Age and gender distribution in dementia

The proportion of the elderly population diagnosed with dementia increases markedly with age: from approx. 0.7 % in the 65-69 years age group to 11 % in the 85+ years age group. Women have a higher life expectancy than men, and women account for just over 60 % of the registered dementia cases.

Young-onset dementia

Approx. 3,000 people under the age of 65 are registered with a diagnosis of dementia, but the validity of the diagnosis in this age group is compromised. In the younger age groups, the numbers of younger men and women are diagnosed with dementia are roughly equal.
