Bruce Willis' wife is sharing new insights into her husband's dementia battle.

Emma Heming Willis, the wife of the "Die Hard" actor, opened up about his frontotemporal dementia diagnosis in a new interview on the "Conversations with Cam" podcast, released Wednesday, Jan. 28.

Heming Willis, 47, shared on the podcast that he is not aware that he has dementia.

"There's this neurological condition that comes with FTD, and other types of dementia as well, called anosognosia, where your brain can't identify what is happening to it," she explained. "So where people think this might be denial – like they don't want to go to the doctor, because they're like 'I'm fine, I'm fine' – actually, this is the anosognosia that comes into play."

She continued, "I think that's the blessing and the curse of this. Bruce never tapped in. He never connected the dots that he had this disease, and I'm really happy about that. I'm really happy that he doesn't know about it."
