Estimate Risk for AD Dementia based on

Computes 5-year risk of developing early symptoms of AD dementia based on demographic factors associated with AD (age, gender, family history, and education).

These estimates are for research or education purposes only. More research is needed before they can be used for clinical practice.

Demographic Risk Factors:

Estimated risk will be computed and displayed here after you answer the questions

Factors used


The greatest risk factor for AD dementia is being older. The older you are, the higher the chance you may develop AD dementia. About 1 in 3 (33%) older adults has AD dementia by the age of 85.back to questions


Women are more likely than men to get AD dementia. About 2 in 3 (or 66%) Americans with AD dementia are women. This difference is partly because women live longer than men, and older age is the greatest risk factor for developing AD dementia.back to questions

Family History

Your risk of AD dementia is higher if family members have had it, especially a parent, sister, or brother. However, even if your parent had AD dementia, this does not mean that you will develop AD dementia.back to questions


In the United States, access to healthcare, housing, food, education and employment impacts people’s health. Not having equal access to these necessities increases the risk of getting many diseases, including AD dementia. Social determinants of health (SDOH) play a role in explaining health differences between groups of people. Education is the most studied SDOH in AD research studies, so we include it in the risk estimate.back to questions
