Malcolm Young, one of the founding members of rock back AC/DC, is battling dementia.

Malcolm Young Has Dementia

Young’s diagnosis was confirmed by his family in a statement to People magazine. "Malcolm is suffering from dementia and the family thanks you for respecting their privacy," the statement read.

Back in April, it was announced that Young, who played guitar for AC/DC over the last four decades, would be taking a break from the band due to poor health.

“After forty years of life dedicated to AC/DC, guitarist and founding member Malcolm Young is taking a break from the band due to ill health,” AC/DC said in a statement on the band’s website back in April. “Malcolm would like to thank the group’s diehard legions of fans worldwide for their never-ending love and support.”

The band added, “In light of this news, AC/DC asks that Malcolm and his family’s privacy be respected during this time. The band will continue to make music.”

More recently, the band released another statement revealing that Young will not be returning to the band. In his place, his nephew Stevie Young will go on their upcoming tour.

“Earlier this year AC/DC released a statement explaining that due to illness, Malcolm would be taking a break from the band. Unfortunately, due to the nature of Malcolm’s condition, he will not be returning to the band,” the new statement reads. “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.”
