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.

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.

The iconic actor, in the midst of a dementia diagnosis, took time to visit first responders battling the Los Angeles wildfires in a rare new video.
