After Barbara's absence from showbiz events sparked rumours about her health, Scott made the decision to speak about the diagnosis to potentially explain any unusual behaviour the acting veteran might display when she's out and about.
He also said Barbara "comes alive" whenever they go out with friends, but he "lives in constant terror" that she might have a panic attack, or "get photographed when she's not looking right". The star became a Dame in 2016 for services to showbusiness and charity.
"I asked that she have an autocue on set, just as a safety net". I'm lucky that my granny still knows who I am, for now.
The TV stalwart's condition has been slowly deteriorating since her last birthday, but her husband, Scott Mitchell, 55, revealed that she was originally diagnosed in 2014 after he and others first noticed signs of her forgetfulness in 2009.
Dame Barbara was said by Ms Moore yesterday to be "thrilled" by the public reaction to the announcement.
The actress, 80, said goodbye to her most famous role, indomitable EastEnders matriarch Peggy Mitchell, in 2016 when the character was killed off at Windsor's own request.
"If you saw the Peggy death scenes, you could see she wasn't reading it".
Barbara was diagnosed with the degenerative condition after hours of mental agility tests, followed by a brain scan and lumbar puncture.

Writing on Twitter he said: 'Very proud of Scott and Barbara for speaking openly about Barbara's diagnosis.
Praising Barbara's husband of 18 years, Pam said: "Scott is absolutely wonderful, I've got so much time for Scott".
"So I went to see him and, without giving the full situation, confided that she was really struggling to learn lines and wouldn't ever be coming back again after this".
"We walked out of the neurologist's office and it was nearly as if she chose to forget what we had just been told". Ruth and I wish the #NationalTreasure that is Dame Barbara Windsor the very best after her Alzheimer's diagnosis'.
Good Morning Britain host Piers Morgan was among the others sending messages to Dame Barbara.
