Dame Barbara Windsor's husband has seen "many changes" in her since she was diagnosed with dementia but he loves that she still has her "humour and wit."
The former 'EastEnders' star's spouse Scott Mitchell announced earlier this year that the 81-year-old actress had been battling the disease - a brain syndrome which affects memory, thinking, behaviour and emotion - for a few years in silence and, although it's been heartbreaking for him to watch her deteriorate, he can still see so much of his wife there because she still has her "humour."
He explained: "The last few years have been really hard for both Barbara and me as we got used to the profound effect dementia has had on our lives.
"I have seen many changes in Barbara since her diagnosis and at times its effects can be stronger than others.
"Despite all the changes in Barbara, there is still so much of her there. Her humour, wit and care for others for example. It is her humour I love the most."
However, Scott - who married the 'Carry On' star in 2000 - still has to remind the legendary star that everyone knows about her battle with dementia now.
He said: "We kept her diagnosis quiet for so long and we were really nervous about going public with the news - but when we did, there was such an incredible reaction of love and support.
"Sometimes Barbara still thinks no one knows about her condition and makes a big thing of keeping it a secret when we see people we know or meet people."
Scott is now planning to run the 2019 Virgin Money London Marathon for his wife and the millions of people around the world who suffer from dementia.
Speaking in a video, filmed at their home, he said: "I don't know how fast I will run it, but for me it is more about completing the marathon, no matter what the time, to show my support for Barbara and all the other people living with dementia."
Barbara also urged people to take part in the marathon to help make a "stand" against dementia and change the attitudes towards the brain condition.
She said: "I'm asking you to make a stand against dementia.
"Taking part will support ground-breaking research to find a cure for a condition that affects so many people, like me. With your help we can and will end dementia with research."
