Alzheimer's Polygenic Risk Score

Alzheimer's disease is the most common cause of dementia. Age and the APOE gene are its strongest risk factors, and this score adds many other common variants.

A risk score adds up many common variants, each with a small effect, into an estimate of genetic predisposition. It is not a diagnosis.
