Overview
- Rumer Willis announced on Monday that she took an APOE genetic test through a partnership with Function and disclosed the result publicly on August 24.
- She reported an average-risk genotype described as "three-four," saying it indicates some increased Alzheimer’s risk but is not determinative.
- Rumer said she is grieving a changed relationship with her father, adding that she "really misses" the earlier version of Bruce Willis and is trying to be present with him now.
- Her father, Bruce Willis, first stepped away from acting after an aphasia diagnosis in 2022 and the family confirmed it progressed to frontotemporal dementia in February 2023.
- Rumer framed testing as practical preparation, noting APOE assesses Alzheimer’s risk rather than frontotemporal dementia, most dementias are not strictly inherited, and she plans to use the data to inform prevention and clinical conversations.
