Casey Kasem Turns 82 in Hospital Being Treated for Dementia

America's DJ Casey Kasem turned 82 on Sunday at Berkley East Convalescent Hospital, where he is being treated for advanced Parkinson's disease and dementia.

The famous former radio personality is widely known as the host of "American Top 40" and for having been the voice of Shaggy in the popular 1970s "Scooby-Doo" cartoons.

Last October, a representative for Kasem's wife Jean told TMZ that the radio icon had just a few months to live as his health had apparently been deteriorating rapidly.

In October, Jean Kasem submitted legal papers to a court in which she stated, "My husband is terminally ill and unable to leave home."

Earlier this month, Kasem's three oldest children went to court to seek conservatorship over their ailing father amid a bitter rift with stepmom Jean, who has been married to Casey for 30 years.

Mike, Kerri, and Julie Kasem, the adult children of the famed radio host and his first wife Linda Myers, claimed in court that Jean Kasem suddenly cut them off from their father in the summer of 2013 as his health worsened.

"We haven't heard anything from her yet. We're giving her a chance to respond privately, and if she doesn't, we're taking legal action," 41-year-old Kerri Kasem told the New York Daily News last October.

"We love him, and everyone knows his kids and grandkids are a source of joy for him," Kerri Kasem added. "My dad told us a long time ago we were not in the will, and we're OK with that. We've known that for years. I've never asked him for anything, nor have I asked Jean for anything."

After a court-appointed lawyer visited Kasem and found his health and daily care to be "adequate," the judge ruled that there was no need for an emergency conservatorship.

Born in Detroit to Lebanese immigrants, Kasem is a member of the Radio Hall of Fame and has a star on Hollywood's Walk of Fame. Having retired from radio in 2009, his weekly rebroadcasts of his "American Top 40" shows from the 1970s and 1980s are still aired in more than 200 radio markets across the country.
