Emma Heming Willis has told fans to "never lose hope" as her husband Bruce Willis continues to battle dementia.
The 44-year-old took to her Instagram Story to share the encouraging message, having earlier admitted "there is no cure" to help her husband fight the degenerative disease.
Bruce was diagnosed with frontotemporal dementia and retired from acting last year, with Emma keeping fans updated on his condition.
Sharing a picture of a beautiful white flower taken in the garden, Emma wrote: "Remember to... Never Lose Hope."
The post comes after she shared "the sad truth" about Bruce's condition.
"The sad truth is is that there is no cure for Alzheimer's or dementia. No amount of vitamin D or B is going to cure a degenerative disease," Emma said in a video.
Emma also said it is important to continue having conversations about dementia as "there is value in prevention."
"I do think that it is important for us to be having this conversation about brain health.
"You know, when I go to my doctor, my doctor is talking to me about the importance of my breast health, my heart health, but he's not having that conversation with me about my brain health."
Emma said doctors should be speaking to people in their 20s about how to look after their brains, instead of leaving it "too late".
She added: "I think we should be talking about our brain health so much more than we do."
Emma finished her video with a powerful message: "One in two people will either develop dementia, care for someone with dementia, or both. Predisposed or not, we're all at risk.
"So, I don't know if you know this, but women make up two thirds of the world's dementia patients and that's just staggering to me. I'm not sure why no one is talking to us about that.
"So, I'm just throwing it out there and I think it's so important for us to talk about dementia. I know it's not the sexiest conversation, no one wants to talk about it, but it's an important one."
