Glen Campbell's Alzheimer's disease has progressed to the point where he needs full-time professional care. 

According to Glen Campbell's wife, Kim Campbell, doctors persuaded her earlier this spring to discontinue care at the family's home.

In an email to The Associated Press, Kim Campbell wrote "It is crushingly sad to see him afflicted with Alzheimer's but indulging those feelings does not help him. I am his wife and no one wants him home more than me but I must do what is in his best interest."

Campbell's daughter Debby told Country Weekly magazine last week that she objected to the move."He does recognize me, and it comes and goes," Debby Campbell told the magazine. "He always knows that I'm a loved one, but whether I'm his daughter or his sister, sometimes he struggles."

Debby Campbell said that she and Campbell's eldest children heard about the decision through news media reports.

Campbell, 78, was diagnosed with Alzheimer's in 2011. He issued two albums and went on a world tour following the diagnosis. Campbell first opened up about having Alzheimer's to PEOPLE in an exclusive 2011 interview. At the time Campbell told People, "I still love making music. And I still love performing for my fans. I'd like to thank them for sticking with me through thick and thin."

Glen Campbell's battle with Alzheimer's disease united his fans in support and sympathy since Campbell and his wife Kim went public with his diagnosis in 2011. Glen and Kim Campbell went public so the "Rhinestone Cowboy" could continue performing as long as possible. Campbell said he didn't want audiences wondering or worrying about him if he forgot lyrics or repeated himself in the banter between songs.

The last tour by Glen Campbell, called The "Goodbye Tour," was filmed for a documentary called "Glen Campbell ... I'll Be Me" which follows Campbell, his wife, and their three adult children - Cal, Shannon, and Ashley. The movie will make its debut Friday at the 2014 Nashville Film Festival. Campbell had to cancel the international tour dates in July 2012 due to his health.

Campbell's 61st studio album, "Ghost on the Canvas" was expected to be his last. But he put out a new collection of songs called "See You There" last December.
On March 26, Campbell was honored with the inaugural Glen Campbell Courage Award at the Alzheimer's Association's A Night at Sardi's event at the Beverly Hilton Hotel.

Campbell had a string of hit singles in the 1960s, including "Wichita Lineman," "Galveston," "By The Time I Get to Phoenix" and "Where's The Playground Susie." He opened for the Doors briefly, with just a guitar in his hand. No backup musicians. The tour didn't last long. At that point he was happier in the studio with his friends.
In 1968, Campbell was named CMA Entertainer and Male Vocalist of the Year. He was inducted into the Country Music Hall of Fame in 2005. Glen Campbell sold more than 45 million albums over the course of his career.  

Glen Campbell was a master instrumentalist. Everyone knows he was great on guitars, but he played bass for the Beach Boys, banjo at the drop of a hat and, well, bagpipes if you pushed him.
