Alzheimer's Risk Isn't Just Family History

Most people think about Alzheimer's risk in terms of family history — did a parent or grandparent have it. That's part of the picture, but it's incomplete. Genetics and blood biomarkers can flag elevated risk decades before any symptoms appear, independent of what you know about your family.

The Sur Alzheimer's Risk Assessment Panel looks at both. It includes ApoE genetic testing, which identifies whether you carry one of the gene variants most strongly linked to late-onset Alzheimer's risk. Carrying one copy of ApoE4 is associated with roughly 2 to 3 times the lifetime risk; carrying two copies raises that to roughly 8 to 12 times. The panel also includes advanced blood biomarkers tied to early amyloid and tau changes, the same processes underlying the plaques and tangles associated with Alzheimer's disease.

None of this is a diagnosis. Elevated genetic or biomarker risk doesn't mean Alzheimer's is inevitable, and a clean result doesn't mean zero risk. What it does is give you and your physician real information, years or decades earlier than symptoms would appear, to have an actual conversation about prevention — cardiovascular risk management, metabolic health, sleep, and the modifiable factors research increasingly ties to cognitive decline.

For patients who take a proactive, longevity-focused approach to their health, this is often where that conversation starts. It's not about living with anxiety over a number. It's about having enough lead time to actually do something with the information.
