What is the life expectancy of a person with Alzheimer's at age 60?

According to a 2025 review of dementia studies, women diagnosed with dementia at age 60 lived an additional 8.9 years on average, while men lived 6.5 years. The life expectancy of a person with Alzheimer's at age 60, part of the 'early-onset' category, can differ significantly based on the individual's overall health and the disease's progression.
