Bruce Willis' wife says it's 'hard to know' if he understands dementia diagnosis amid recent public appearances

Bruce Willis has been diagnosed with frontotemporal dementia, a degenerative brain disease affecting behavior, language, and movement.
His wife Emma Heming Willis described the challenges of dementia for both Willis and their family in a tearful interview.
It's unclear if Willis comprehends his diagnosis, as dementia can impede self-awareness.
Willis retired from acting in 2022 and was recently spotted out in public for the first time since his diagnosis was announced.
His family aims to raise awareness about dementia and provide support for other families facing it.
