Tony Bennett‘s family has revealed that the 94-year-old singer is living with Alzheimer’s disease.

In an article published in AARP The Magazine, Bennett’s wife Susan says he was diagnosed back in 2016 after he started to show signs of decline. She says although his condition has progressed, he’s “been spared the disorientation that can prompt patients to wander from home, as well as the episodes of terror, rage or depression.”

Bennett’s doctor, who diagnosed him, says that despite some cognitive problems, “He is doing so many things, at 94, that many people without dementia cannot do. He really is the symbol of hope for someone with a cognitive disorder.”

Susan, who is the singer’s third wife, says she understands the end is near and just hopes he eventually goes peacefully.
