Willis' family announced in 2023 that the "Die Hard" actor was diagnosed with the "cruel disease" frontotemporal dementia.
"While this is painful, it is a relief to finally have a clear diagnosis," the family said on the Association for Frontotemporal Degeneration website.
"FTD is a cruel disease that many of us have never heard of and can strike anyone. For people under 60, FTD is the most common form of dementia, and because getting the diagnosis can take years, FTD is likely much more prevalent than we know," they continued.
The disease, which can alter personality, has no cure.
According to the Mayo Clinic, symptoms of FTD vary from person to person and usually get worse over time.
Early symptoms can include a change in behavior, difficulty staying organized, changes in speech, and lack of interest, often called apathy.
FTD is often misdiagnosed as Alzheimer's, though it usually is found in younger patients.
Bruce Willis' Mental Health is Waning
Three years after his diagnosis, Willis has reportedly "declined a lot mentally" and is "living in his own world."
"Sometimes he looks like a baby who is staring at an object with curiosity, just taking it in," a source told the Daily Mail Sunday. "But if you look at him, he appears like a healthy middle-aged man."
The inside source added that the Hollywood actor is unaware of his waning mental health.
"He knows his life is different, but he doesn't think it is that different," the individual claimed. "He doesn't talk about it or even complain much. [Willis] senses something is off, but he doesn't have a full grasp of it."
Willis' wife, Emma Heming Willis, has previously spoken about the emotional challenges of watching her husband's condition progress.
In September, she described the "constant state of grief" she experiences while caring for the actor.
"It's natural — we all want our loved ones to be healthy, full of life and [be] the person they always were," she said in an interview. "But FTD is a devastating illness that steals things from you very slowly."
