In interviews reported by both outlets, Willis describes how aspects of his character have shifted over time, focusing on changes she has observed in his demeanor and behavior. The Independent quotes Rumer discussing his earlier personality, describing him as having been “this kind of macho dude,” while indicating that the diagnosis has brought differences from how he was before. The Mirror similarly reports that Rumer has offered insight into the effects of the condition following the announcement of the dementia diagnosis. The coverage does not present new medical details beyond the earlier diagnosis timeframe, but rather centers on her account of day-to-day changes. Together, the reports present a consistent theme: since the February 2023 diagnosis of frontotemporal dementia, Rumer has observed and discusses changes in Bruce Willis’s personality.
