Rumer Willis undergoes genetic test for Alzheimer risk amid father's dementia fight

Rumer Willis, 38, collaborated with the health service Function to complete an APOE genetic screening aimed at measuring her likelihood of developing Alzheimer’s disease, motivated by her father Bruce Willis’s frontotemporal dementia. She posted on Instagram that the test felt terrifying but important, and later shared with People that the outcome showed a "pretty average" risk. Willis highlighted the emotional difficulty of caring for her dad while confronting her own health concerns.

She noted a family history that also includes breast cancer and other conditions. The actress stressed that having information empowers her to act early and potentially avoid severe health declines later in life. Her sisters Tallulah and Scout have also spoken publicly about their father's condition.
