Frontal Lobe Dementia at 52? Wow. I have heard of them, but never quite got into this group. There were other punk rockers at the time. They ushered in a style though.
My guess is what would be the stereotypic outcome for many rockers; He did lots of drugs years ago, and hastened his own decline.
Beastie Boys weren’t punk. They were probably the very first band to fuse rock with hip hop.
There’s tons and tons of musicians that didn’t die from disease, drugs or alcohol. We know Bowie died of Cancer, I don’t think Prince’s cause of death was released yet. Alvin Lee of Ten Years After died of complications after stomach surgery. Ronnie James Dio of Black Sabbath, Rainbow and Dio died from stomach cancer. Clive Burr of Iron Maiden died from MS. Stevie Ray Vaughan died in a helicopter crash (this after getting sober) when he was 35.
The “rock star” lifestyle is much too glorified.
I don’t really call it punk, but I think represents The Beasties at their peak -

According to http://www.healthline.com/health-slideshow/frontal-lobe-dementia-symptoms-causes-treatment#4, “Frontal lobe dementia has one known risk factor: your genes.” and “Frontal lobe dementia shortens a person’s life span. According to the Alzheimer’s Association, most people with a frontal lobe dementia disorder live an average of six to eight years after the first symptoms appear. In some cases, people live as few as two years.”
