Former EastEnders star Dame Barbara Windsor, 82, who is widely known for starring as Peggy Mitchell on the BBC soap, was diagnosed with Alzheimer’s five years ago, but Scott only spoke out about the news last year.
The actress’ husband Scott Mitchell, 56, has now revealed Barbara’s “memory comes back” when she sings.
Speaking to The Mirror, he said: “It’s a very common thing, music. Music triggers the brain.
“It’s really heartening to see as she taps into a place that has strong memory and evokes happiness.”
Scott has previously said that while his spouse needs 24-hour care, this doesn’t stop her from enjoying nights out.
“Dementia is a progressive illness, and you know you are heading in one direction, but she still has her wonderful sense of humour and we still laugh and have a giggle.” he added to the publication.
Earlier this week, Dame Barbara Windsor posed for pictures during a rare night out to see Les Miserables.
After the performance, the Carry On star went backstage to meet the stars of the show Matt Lucas and Michael Ball.
Matt took to his Instagram to share a picture of the trio beaming for the cameras.
In view of his 76,000 followers, he wrote: “Another day, another superstar in the audience at Les Mis.”
Many of the actor’s social media fans flocked to his page to comment on the post.
One user wrote: “Lovely photo of three lovely people,” while another added: “Now there is a photo to treasure xx.”
“Ah Bless Her, National Treasure,” a third penned.
Elsewhere this week, Barbara’s former co-star Kellie Shirley discussed Barbara’s progress with stand-in host Christine Lampard on Lorraine.
The actress said she had recently visited Barbara with her children.
Sharing details about their day, she said: “We all went out for a lovely little cream tea thing.
“She was on form. She’s got such a sparky, fun personality. She’s so infectious to be around.
“She puts on a performance I suppose when she’s with all of us.”
Earlier this year, Kellie took on the Memory Walk Half-Marathon to help raise money for the Alzheimer’s Society.
Virgin Radio presenter Chris Evans, along with 50 fellow marathon runners, also took part in the Amsterdam marathon for Dementia Revolution this year.
Speaking of his involvement, Scott said: ”I want to say a massive thank you to Chris Evans and all the victorious bidders for standing with Dementia Revolution.
“What an incredible amount they have raised to help fund life-changing research and help people like Barbara.
“Without Chris and each of the 50 bidders we would not have reached the milestone £4 million to make the Dementia Revolution the most successful Charity of the Year ever for Virgin Money London Marathon.”
