AC/DC guitarist Malcolm Young is not returning to the band he co-founded due to his declining health, the musician's family confirms.
"Malcolm is suffering from dementia and the family thanks you for respecting their privacy," a statement to People magazine reads.
The unfortunate news comes six months after it was announced the 61-year-old would be taking a break from music due to illness.
"Malcolm would like to thank the group's diehard legions of fans worldwide for their never-ending love and support," the rock group wrote on their website at the time.
The band, which formed in 1973, is preparing to release its 17th studio album, Rock or Bust, this December, the first without Malcolm in more than four decades.
"AC/DC will undertake a world tour in support of Rock or Bust in 2015. Stevie Young, nephew of founding members Angus and Malcolm Young, plays rhythm guitar on Rock or Bust and will accompany the band on tour," a statement from the group revealed.
Back in July, AC/DC frontman Brain Johnson told Classic Rock, "We miss Malcolm, obviously. He's a fighter. He's in [the] hospital, but he's a fighter. We've got our fingers crossed that he'll get strong again...Stevie, Malcolm's nephew, was magnificent, but when you're recording with this thing hanging over you and your work mate isn't well, it's difficult. But I'm sure [Malcolm] was rooting for us."
People was the first to confirm news of Malcolm's illness.
