Alzheimer's Life Expectancy Calculator

Select the current GDS stage. Stage 4 is when Alzheimer's dementia is typically first diagnosed.
Age when Alzheimer's was officially diagnosed. Younger age at diagnosis generally correlates with longer survival.

Women with Alzheimer's tend to live about 18% longer than men on average, based on large cohort studies.
Comorbidities such as diabetes, heart disease, stroke history, and cancer significantly shorten survival in Alzheimer's patients.

Current stage: Moderate cognitive decline (mild dementia). Estimated median survival: 6.3 years.

  • The median survival estimate is 6.3 years from this stage, with a likely range of 3.1 to 8.4 years.
  • Age at diagnosis is one of the strongest predictors: people diagnosed at 75 have a longer-than-average expected course compared with this model's reference age of 78.
  • Among women, published cohort studies report a median survival of approximately 5.1 years from the point of diagnosis (all stages combined).
