Susan Crow on Husband Tony Bennett's Alzheimer: 'He Doesn't Know He Has It'

Tony Bennett is one of the most famous voices in the world, and even at the age of 95, he hasn't lost the talent that made him the legend that he is today.

However, the singer's mind is not what it used to be, and during a recent interview with Anderson Cooper, Susan Crow, Bennett's wife, claimed he is not aware that he has Alzheimer's.

According to Crow, her husband, whom she describes as "very sweet," recognizes her as well as his children, and she believes that they are "blessed in a lot of ways."

A SECRET WELL-KEPT

The singer's family first revealed that he suffered from Alzheimer's' back in February, but that they learned of the diagnosis in 2016, adding that he is "incapable of understanding the disease."

When asked by Cooper if his last show was a "sad story," Gaga said that it was not sad but it was emotional.

WHAT ARE THE SYMPTOMS

Alzheimer's, which can lead to dementia, is often characterized by memory loss, but it can also cause those who suffer from it to lose the ability to recognize loved ones, speak to them, or even understand them.

Not only that, but Alzheimer's patients can often experience episodes of rage, terror, and depression but, thankfully, Bennett has been spared such symptoms.

According to Dr. Gaytari Devi, who diagnosed Bennett with the disease, the star knows who he is and how he has to behave, a memory that is deeply connected to his musical talent. She added:

"That's an area of the brain that's just so an innately hardwired part of his brain. And it's also an area of his brain that gives them real meaning and purpose in his life..."

STILL GOT IT

During the "60 Minutes" talk, the 95-year-old performed a song with his pianist without the need for a music sheet or have the lyrics in front of him.

Despite his advanced age, Bennett performed one last time in August at New York's Radio City Music Hall alongside friend and frequent collaborator Lady Gaga.

When asked by Cooper if his last show was a "sad story," Gaga said it was not sad but it was emotional, in the sense that it is hard to watch someone change:

"I think what's been beautiful about this, and what's been challenging, is to see how it affects him in some ways, but to see how it doesn't affect his talent."

The pop star also described their final collaboration as a "gift," which she will hold in her heart until her last breath, stating that the time she spent with Bennett has changed her forever.
