Demi Moore is reportedly making her ex-husband Bruce Willis' 'peace and comfort' her 'central mission' as he continues his battle with frontotemporal dementia

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.
