Read on to learn more about dementia life expectancy, the stages of the condition, and the outlook for a few common dementia subtypes.
Dementia life expectancy
According to a
- 4.6–5.1 years after diagnosis for females
- 4.1–4.3 years after diagnosis for males
However, as the researchers note, many factors can influence life expectancy, including the age at the time of diagnosis and the type of dementia.
Stages of dementia
Dementia can be broken down into
Early stage dementia
Symptoms can be subtle in the earliest stage. A person may experience symptoms

Eventually, people with late stage dementia lose the ability to walk and talk. Some people with dementia die of dementia-related complications. Others may die due to another condition, such as heart disease or cancer.

Vascular dementia outlook
The average life expectancy for vascular dementia is also lower than it is for Alzheimer’s disease. Researchers estimate that females live
Because acute events like a stroke can cause vascular dementia, the symptoms

Your care team may also recommend a variety of
- eating a balanced diet full of fruits and vegetables
- getting regular physical activity
- getting enough high quality sleep
