Glen Campbell has been moved into a care facility three years after being diagnosed with Alzheimer's disease, People.com reports.
"He was moved to an Alzheimer's facility last week," a family friend told the title. "I'm not sure what the permanent plan is for him yet. We'll know more next week."
The singer, whose "Rhinestone Cowboy" topped the charts in 1975, had been suffering from short-term memory loss in recent years. He was diagnosed with Alzheimer's disease in early 2011.
The 78-year-old Grammy winner and his wife Kim initially shared the news of his illness back in 2011 because he’d hoped to give a series of goodbye concerts, in conjunction with an album "Ghost on the Canvas,” which was released later that year.
"Ghost on the Canvas” (Surfdog), Campbell’s 61st studio album, was expected to be his last. It wasn’t. A brand new collection of recordings from the legendary singer, "See You There" (Surfdog) was released last December. With Campbell’s health apparently in decline, it’s increasingly likely the collection will be the final studio recording of the Arkansas native's career.
The latest health setback comes just days before the documentary of that final tour, titled “Glen Campbell... I'll Be Me,” gets its world premiere April 18 at the 2014 Nashville Film Festival.
Campbell was named both CMA Entertainer and Male Vocalist of the Year in 1968, and was inducted into the Country Music Hall of Fame in 2005. The veteran performer has sold more than 45 million albums over the course of his career.
