Veteran actor and activist Danny Glover has revealed that he is living with Alzheimer's disease, saying he is still trying to come to terms with the diagnosis.

Glover, widely known for playing the calm and dependable police officer in the Lethal Weapon film series, said he was diagnosed with the progressive brain disease three years ago.

The four-time Emmy Award nominee, who will turn 80 on July 22, shared the news in separate interviews with NBC's Today show and People magazine.

"I'm still not accepting in my mind all parts of it," Glover told People. "There are the moments that you keep remembering that validate the fact that you can remember stuff. And there are moments I'll never forget."

Alzheimer's disease is the most common form of dementia. It gradually affects memory, thinking and daily functioning. More than 6 million people in the United States and millions more worldwide are living with the condition.

Throughout his career, Glover has received four Emmy Award nominations and was honoured with an honorary Oscar in 2022. He has also been recognised by the NAACP and Black Entertainment Television, and has earned nominations from the Screen Actors Guild.

Beyond acting, Glover has been active in humanitarian work. From 1998 to 2004, he served as a goodwill ambassador for the United Nations Development Programme, supporting efforts to address poverty, disease and economic development in Africa, Latin America and the Caribbean.
