Mortality from dementia
Dementia disorders are fatal. On average, a person with a dementia disorder lives 5 to 8 years after the diagnosis.
Dementia disorders evolve gradually and are ultimately fatal. However, some people live for many years with dementia. It is believed that dementia is the fourth most common cause of death in Denmark with cancer, heart diseases and respiratory diseases being more frequent causes of death.
The table displays 1- and 5-years survival rates for women and men aged 65-69 years and 90+ years.
| Women | Men | |||
| 65-69 y | 90+ y | 65-69 y | 90+y | |
| 1-year survival | 90 % | 60 % | 88 % | 50% |
| 5-year survival | 62% | 10 % | 54 % | 5 % |
