It may be that dementia is claiming another giant, this time a musical one.

AC/DC co-founder, guitarist and songwriter Malcolm Young, whose retirement from the band was announced on Wednesday, has been moved into full-time care in a nursing home facility in Sydney's eastern suburbs specialising in dementia, sources connected to the Young family have said.

The home is understood to be Lulworth House in Elizabeth Bay, the same facility that is home to Gough Whitlam and, until his recent death, Neville Wran, who was afflicted with dementia in his last years.
