Dame Barbara Windsor no longer recognises her own home, according to her husband of 19 years Scott Mitchell.

Mr Mitchell, 56, gave an update on the 81-year-old Dame’s health following the announcement five months ago that she had been diagnosed with Alzheimer’s four years before.

“There’s good and bad days,” he told BBC Radio 2’s Steve Wright in the Afternoon programme on Wednesday.

“The confusion does progress and that becomes a lot more stressful for her to live with and you as the carer to watch.”

Having previously revealed that the legendary actress, famous for her 22 year run as Peggy Mitchell in Eastenders, is in need of constant care and cannot be left alone, Mitchell appeared on the show to discuss his plans for running in the London Marathon in aid of the Dementia Revolution Campaign.

“I think what I’ve learnt by talking to other people is its very different for every case. It’s very simple things that used to be very easy, whether that’s signing something or writing a letter, opening something,” he said.

“At times it’s very frustrating and irritable. It gets worse at night. With Barbara it’s to do with our house. She constantly asks me over and over again at night whose house is this, are we staying here, is this the house I grew up with my mummy.”

The latest update on the Dame’s condition comes after Eastenders co-star Kellie Shirley, who plays Carly Wicks in the BBC soap, revealed Dame Barbara struggles to remember the names of her friends and former colleagues.

“A massive part of being an actor is remembering things. Your memories are such a big part of who you are. That’s why I feel for Barbara. She remembers so much about the past as clear as day yet she won’t remember my name,” she told the Daily Express.

Kellie is joining Scott in the London Marathon next month to raise money for Alzheimer’s research.

“We meet up on a Friday, run together and catch up. I find running so boring so chatting makes the time go faster,” she added.
