Barbara’s husband Scott, 55, confirmed Barbara Windsor has been battling Alzheimer’s, the most common cause of dementia, for four years and has been taking medication.
He also revealed the 80-year-old actress broke down in tears when the doctor diagnosed her in a candid interview with The Sun.
Piers, 53, took to Twitter to pen an emotional message to the actress, in view of his six million followers.
Alongside a picture of him with Barbara from her time on his show Life Stories, he wrote: “Sending my love & support to the fabulous Dame Barbara Windsor, one of my favourite people.
“Alzheimer’s is a horrible thing. She & Scott going public about it like this is a typically gutsy decision by one of the gutsiest ladies I know. We’re all rooting for you, Babs!”

Lorraine Kelly, 58, also took to Twitter to send her wishes.
In view of her 111,000 followers, she wrote: “Such sad news about Barbara Windsor – a funny, kind, generous, big hearted woman. Alzheimer’s is a very cruel disease.
“I hope she knows how much she is loved. Thoughts with her husband Scott.”
Scott told the publication he could not hide Barbara’s condition as it has slowly progressed since her 80th birthday last August.
He explained: “I can’t protect her any longer. I’m doing this interview — and I would like to make clear that I’m not being paid for it and it’s the only one I’ll be doing — because I know that rumours are circulating in showbusiness circles.
“And, since her 80th birthday last August, a definite continual confusion has set in, so it’s becoming a lot more difficult for us to hide.

“I didn’t want someone else to dictate how or when the diagnosis came out, so that’s why I’m speaking about it now,” he added.
During the interview, Scott also said he thought Barbara was ashamed of her condition and asked if the public knew about her diagnosis.
“Unfortunately, I notice she feels a kind of shame about it,” he explained. “There’s a vulnerability there and I keep telling her, ‘Bar, no one will think you’re silly for having this’.
“I explain that if someone has cancer, no one looks at them and thinks ‘How ridiculous’. We sympathise and it’s the same with this.”
Scott revealed he has spoken out about the brain disorder to support families going through a similar situation.
He said: “I hope speaking out will help other families dealing with loved ones who have this cruel disease.
“Secondly, I want the public to know because they are naturally very drawn to Barbara and she loves talking to them.

“So rather than me living in fear she might get confused or upset, they’ll know that if her behaviour seems strange, it’s due to Alzheimer’s and accept it for what it is.”
Barbara’s showbiz career includes her appearances in several Carry On films in the 60s and 70s and her infamous role as feisty Peggy Mitchell in EastEnders.
In 2016 Barbara was appointed Dame commander of the Order of the Empire for her services to charity and entertainment.

Jeremy Hughes, Chief Executive Officer at Alzheimer’s Society, says: “We were saddened to hear that Barbara Windsor has been diagnosed with Alzheimer’s Disease – but we applaud her husband Scott’s decision to speak out about her condition.
“Stigma around dementia still exists, and many people are facing it in the shadows. ‘Babs’, a true cultural icon, is much loved, and speaking out about her experiences will no doubt shine as a beacon for others wanting to live well with dementia.
“We are here to support people like Barbara and want to reach everyone with a dementia concern or diagnosis. We would urge anyone concerned about dementia, or supporting a loved one with the condition, to contact us.”
