Who is prone to dementia?

Dementia mainly affects people over the age of 65 (one in 14 people in this age group have dementia), and the likelihood of developing dementia increases significantly with age. However, dementia can affect younger people too.

Who is most at risk for dementia?

The greatest known risk factor for Alzheimer’s and other dementias is increasing age, but these disorders are not a normal part of aging. While age increases risk, it is not a direct cause of Alzheimer’s. Most individuals with the disease are 65 and older. After age 65, the risk of Alzheimer’s doubles every five years.

Does dementia run in families?

The majority of dementia is not inherited by children and grandchildren. In rarer types of dementia there may be a strong genetic link, but these are only a tiny proportion of overall cases of dementia.

What is the average lifespan of a person with dementia?

Worldwide, women with dementia outnumber men 2 to 1. Brain scans tell us that the rate at which brain cells are dying in the brain is faster in women than in men. Women are more likely to live longer than men. However, although risk increases with age, dementia is caused by diseases of the brain not age alone.
