Glen Campbell has recently moved into a special care facility. The 78-year-old country music legend has been suffering from Alzheimer's for over three years.
A friend tells PEOPLE.com, "He was moved to an Alzhemier's facility last week. I'm not sure what the permanent plan is for him yet. We'll know more next week."
The "Rhinestone Cowboy" first opened up about having Alzheimer's in 2011.
Campbell and his fourth wife, Kim Woolen, wanted his fans to be aware of his condition in case he forgot lyrics or flubbed a song during his a final farewell live tour.
The "Goodbye Tour" tour was filmed for a documentary called "Glen Campbell … I'll Be Me", which will make its debut Friday at the 2014 Nashville Film Festival. The documentary follows Campbell, his wife, and their three adult children – Cal, Shannon, and Ashley – as they deal with the various stages of the disease and perform on the road together.
