Willis was diagnosed first with aphasia -- a condition where the brain's ability to understand or express language is impaired, according to the National Institutes of Health -- in 2022 before receiving an additional diagnosis of frontotemporal dementia in 2023, according to his family.

In what’s believed to be his first public sighting since retiring from acting, Bruce Willis made sure to thank first responders battling the blazes in Los Angeles.

Bruce Willis’ wife Emma Heming shared a new video of the actor thanking first responders amid the wildfires in Los Angeles, marking his first appearance since dementia diagnosis. Spencer Pratt and Heidi Montag have lost everything after their Pacific Palisades home burned down in the California fires last week.

Last month, Bruce's ex-wife, Demi Moore, gave an update on his well-being amid his battle with dementia. In an interview with CNN, the 62-year-old actress explained that the actor is "in a very stable place," but it hasn't been easy watching him struggle.

In an Instagram post shared by his wife Emma Heming Willis on Thursday, Willis can be seen shaking hands with a Los Angeles police officer.

Bruce Willis retired from acting in 2022 and was then diagnosed with frontotemporal dementia. He's rarely been seen in public since then.
