Dementia in Denmark

The exact prevalence of dementia in Denmark is unknown but according to the Government Agency for Health Data 35,100 elderly Danes (65+ years of age) are registered with a diagnosis of dementia in the National Patient Registry. Dementia may, however, be underdiagnosed in Denmark. Combining meta-analyzed estimates of dementia prevalence rates based on Western European epidemiological studies presented in World Alzheimer Report 2015 with population figures from Statistics Denmark the prevalence of elderly (60+ years of age) with dementia can be estimated to approximately 87,000 persons in 2017.

Due to a steady increase in average life expectancy and longevity the number of Danes with dementia is expected to increase over the next decades. In the future the number of people suffering from dementia will grow and consequently the socio-economic burden will continue to increase.

By 2040 there will be approximately:

  • 150,000 Danes with dementia

By 2050 there will be approximately:

  • 18.66 million Europeans with dementia
  • 131.45 million people in the world with dementia

Prevalence of dementia in Denmark

The exact prevalence of dementia in Denmark is unknown but according to the Government Agency for Health Data 35,100 elderly Danes (65+ years of age) are registered with a diagnosis of dementia in the National Patient Registry. According to the Danish Health Authority a further 3,000 ‘young’ Danes (less than 65 years of age) are registered with a diagnosis of dementia increasing the total registry-based ‘prevalence’ to approximately 38,100 Danes.

Registry-based prevalence of dementia in 2014:

Age range Women Men Total
65-69 1,200 1,500 2,700
70-74 2,000 2,100 4,100
75-79 3,500 2,700 6,200
80-84 5,100 3,000 8,100
85-89 5,800 2,400 8,200

Incidence of dementia in Denmark

The exact incidence of dementia in Denmark is also not known but according to the Danish Health Authority approximately 7,200 Danes are newly registered with a diagnosis of dementia per year (annual average for 2010-2012).

Estimated dementia prevalence

Dementia may, however, be underdiagnosed in Denmark. Combining meta-analyzed estimates of dementia prevalence rates based on Western European epidemiological studies presented in World Alzheimer Report 2015 with population figures from Statistics Denmark the prevalence of elderly (60+ years of age) with dementia can be estimated to approximately 87,000 persons in 2017.

As dementia prevalence is strongly associated with age and as the elderly population will be steadily increasing according to projections provided by Statistics Denmark a significant growth in numbers of people with dementia should be expected over the next decades.

Year Projection of the elderly
population (aged 60+)
Estimate of elderly
with dementia (aged 60+)
2017 1,435,346 87,319
2020 1,504,341 93,506
2025 1,638,715 106,877
2030 1,766,528 122,738
2035 1,850,019 138,097
2040 1,888,297 149,882

Source: Population projections provided by Statistics Denmark (2017). Prevalence estimates calculated by the DDRC.

We expect the prevalence of dementia in Denmark to increase by 50% in 2030 and perhaps 70% in 2040 – unless effective risk reduction strategies or curative treatments are implemented in the meantime.
