Bruce Willis’ daughter Rumer shares how dementia battle has changed actor’s ‘macho dude’ personality

The actor’s 37-year-old daughter also accepted that until her father’s diagnosis of frontotemporal dementia (FTD), she “had no idea” how “prevalent” the neurological condition is. “It’s wild to me. So many people come up to me now and they say, ‘My uncle had FTD. My dad had this’,” she added.

In November 2025, Rumer had given an update on her father’s health, revealing that he was different but still had a “spark” in him. “The truth is that anybody with FTD is not doing great. But he’s doing okay in terms of somebody who’s dealing with frontotemporal dementia, you know what I mean?” she said, during an Q&A session on Instagram.

Bruce Willis dementia diagnosis

Bruce Willis has been avoiding the limelight since his frontotemporal dementia (FTD) diagnosis. In 2022, the 71-year-old’s family confirmed his aphasia diagnosis. It is a language disorder caused by brain damage. A year later, the family opened up about his frontotemporal dementia. “While this is painful, it is a relief to finally have a clear diagnosis,” their post on social media read.

Last year, during an interview with Diane Sawyer, his wife Emma Heming Willis had said, “Bruce is still very mobile. Bruce is in really great health overall, you know. It’s just his brain that is failing him… The language is going, and, you know, we’ve learned to adapt. And we have a way of communicating with him, which is just a… different way.”
