Rumer Willis shares another heartbreaking update about his father, Bruce Willis.

The “Die Hard” star now has frontotemporal dementia, a progressive brain disorder, after being diagnosed with aphasia for the first time in 2022. His eldest daughter struggled on Friday to describe how her father was doing.

“People always ask me this question,” he said in an Instagram Q&A. “And I think it’s a little difficult to answer, because the truth is that anyone with FTD doesn’t do very well. But they do well in terms of someone who is dealing with frontotemporal dementia, you know what I mean?”

The 37-year-old noted that she could simply say, “You’re doing great,” but explained that “those parameters don’t work anymore.” She gave more details in a separate Instagram story on Friday.

“The answer I would give is that I am very happy and grateful to be able to go hug him,” she said. “I’m so grateful that when I go there and give him a hug, whether he recognizes me or not, he can feel the love that I’ve given him and I can feel it back.”

Willis married fellow actress Demi Moore in 1987 and welcomed Rumer and her sisters Scout and Tallulah before the couple finalized their divorce in 2000. He has since had two more children with his second wife, Emma Heming Willis, whom he married in 2009.

Heming Willis revealed earlier this year that her husband’s brain is “failing him” and that “language is failing.”

FTD is the result of neuronal damage in the frontal and temporal lobes of the brain. It can cause unusual behaviors, communication problems and emotional problems, according to the National Institute on Aging. There is no cure, says the Association for Frontotemporal Degeneration.

Rumer Willis, who welcomed her first daughter, Louetta Isley Thomas Willis, in 2023, finally ended on a note of gratitude on Friday, saying, “I still see a spark of him and he can feel the love that I’m giving him, and that feels really nice.”

She continued, “I feel grateful that I get to go there with Lou and spend time with him. And I can feel the love that he has for me and that he gives me, and I get to love him and be with him.”
