Dementia reduces life expectancy by about 2 years for those diagnosed at age 85, 3 to 4 years for those diagnosed at 80, and up to 13 years with a diagnosis at 65, researchers reported in a study published Jan. 8 in The BMJ.

Learn how long men and women tend to live after a dementia diagnosis and why the time of nursing home admission is a crucial detail for researchers.

The average life expectancy figures from diagnosis varied from 2.2 years for men diagnosed in their mid-80s, to 8.9 years for women diagnosed around the age of 60. Such a broad range of outcomes could affect all kinds of decisions about life planning and future care.

A new study has revealed that dementia reduced life expectancy by about two years for people with a diagnosis at age 85, 3-4 years with a diagnosis at age 80, and up to 13 years with a diagnosis at age 65.

DEMENTIA is a devastating diagnosis, often described as robbing people of their ability to think, learn and remember. As dementia progresses, it damages the brain so much it eventually affects

The average life expectancy of people diagnosed with dementia ranges from 9 years at age 60 to 4.5 years at age 85 for women and from 6.5 to just over 2 years, respectively, in men, finds a systematic review of the latest evidence in The BMJ today.

Researchers examined all studies between 1984 and 2024 which reported on survival or nursing home admission for people with dementia. A total of 235 studies reported on survival among more than 5.5 million people and 79 studies reported on nursing home admission among 352,990 people.

Average life expectancy for patients with dementia ranges from 8.9 years after diagnosis at a mean age of 60 years for women to 2.2 years at a mean age of 85 years for men, according to a study published online Jan.
