Convenient APOE4 dementia genetic test
15-min online consultation with a dementia specialist
Access to our online dementia prevention center
The APOE4 gene is the most reliable genetic marker for dementia risk, backed by decades of research and thousands of studies. It’s directly linked to amyloid plaque buildup, tau tangles, and brain inflammation—key drivers of Alzheimer’s. Found in up to 25% of the population, its strong association with cognitive decline (up to a 20x higher risk) makes it the gold standard for genetic dementia testing.
Getting genetic results can feel overwhelming—but with BetterBrain, a dementia specialist is here to help you make sense of them. You'll receive your results in a personalized online consultation, where they’ll clearly explain what your results mean, what they imply for your brain health, and what your best next steps are.

Schedule a blood draw from 1 of our 2,000 partner labs, or choose an at-home blood draw for extra comfort.
Your results will be available within 5 days and will be personally explained to you by a dementia specialist who will help you understand the results & implications.
Uncovering high pTau levels doesn't mean you're powerless. Join BetterBrain's prevention program to take back control and reduce your overall risk.
While a specialist will go over your results with you in detail, here’s how the APOE test works to assess your risk.
