Glen Campbell has been moved into a health care facility following a three-year battle with Alzheimer's disease.
"He was moved to an Alzheimer's facility last week," a family friend told the magazine. "I'm not sure what the permanent plan is for him yet. We'll know more next week."
The 78-year-old Country Music Hall of Fame member confirmed his diagnosis in 2011 and embarked on a farewell tour that ended in 2012. He released a new album, See You There, in December.
In announcing the diagnosis, Campbell and his wife wanted fans to understand his medical condition before the tour began. Despite occasional problems reading the song lyrics from an onstage video monitor, the shows were spirited and upbeat, and he was in excellent form as a guitarist.
He and his family were recently honored with the Alzheimer's Association first-ever Glen Campbell Courage Award during ceremonies in Los Angeles. The award recognizes their personal bravery for sharing their story with the public and calling attention to the disease.
His final tour was filmed for Glen Campbell ... I'll Be Me, a documentary debuting today (April 18) at the 2014 Nashville Film Festival. The film features footage of Campbell, his wife and their three adult children as they dealt with the effects of the disease while traveling together.
