APOE4 and Alzheimer’s risk: what the numbers actually mean
Relative risk, absolute risk, and age of onset: how to read the scary statistics about APOE4 and Alzheimer’s, with real ranges and the hopeful part that gets buried.
Field notes for APOE4 carriers
Just found out you carry APOE4? One copy roughly triples Alzheimer’s risk and two copies raise it further, but a large share of that risk is modifiable. We turn the research, podcasts, and expert guidance into clear steps for protecting your brain and heart, with the real numbers and the honest uncertainty left in.
Free, and built for carriers by people who actually read the studies.

APOE4 does not only affect the brain. It shapes how your body handles cholesterol, which makes cardiovascular health the most concrete, trackable, and treatable lever carriers have.
APOE4 is the most common genetic risk factor for late-onset Alzheimer’s. What the gene does, what carrying one or two copies means, and the crucial things it does not mean.
