Emma Heming Willis says that holidays remain "joyous" with her husband Bruce Willis

Emma - who has daughters Mabel, 13, and Evelyn, 11, with Bruce - told People: "It's joyous. It's just different.

"Bruce loved Christmas and we love celebrating it with him. It just looks different, so we've kind of adapted to that."

Emma knows that the festive period can be "so hard" for the families of those suffering with dementia, although she joked that people should watch her husband's 1988 action movie that takes place at Christmas.

She quipped: "I think it's important to put Die Hard on because it's a Christmas movie."

Emma continued: "You have to learn and adapt and make new memories, bring in the same traditions that you had before.

"Life goes on. It just goes on. Dementia is hard, but there is still joy in it. I think it's important that we don't paint such a negative picture around dementia. We are still laughing. There is still joy. It just looks different."

Emma revealed that she has a "very simple" life with Bruce, 70, and their children.

She said: "(Life) is very simple - it actually always has been. I think that's just being able to be present with him, that is the joy. Me being able to be his wife with him. Those are the moments."

Emma had recently lamented how she and The Sixth Sense actor were left with "no hope, no direction (and) no support" when he was diagnosed with frontotemporal dementia two years ago.

She told Yahoo!: "The day we received the diagnosis, we walked out of that appointment with nothing - no hope, no direction, no support. I wasn't really given any information other than just the nuts and bolts of FTD.

"In looking back, I just think that's so crazy. It was such a traumatic experience, like your whole life is being ripped from you in a moment.

"After that appointment, I started digging into research online to really understand: What was this diagnosis? How does it impact my husband? How does it impact our family? With FTD, those early years are so hard because you're trying to figure it all out in real time and learning things on the fly. It's a progressive disease.

"So, in the beginning, your person can still manage some things, and then slowly the needs start changing and the things that they used to be able to do they can't do anymore. You have to rev up the support."
