The family of AC/DC's founding member Malcolm Young has confirmed the rocker is being treated for dementia, which has forced him to leave the band.
"Malcolm is suffering from dementia and the family thanks you for respecting their privacy," Young's family said in a statement, according to People.
Last April, the band announced Young's break from the AC/DC and said they would be recording their 17th studio album, "Rock or Bust", without him. Young's nephew, Stevie Young, replaced Malcolm on the album. He will also be filling in for Malcom during AC/DC's 2015 world tour.
Our thoughts are with the Young family. We wish Malcolm all the best and would like to thank him for following his dreams, which led him to create one of the most influential and bad-ass rock bands of all time. His contribution and legacy has inspired, and always will inspire, hoards of musicians to keep rock alive.
