Ozzy Osbourne breaks silence on Parkinson's diagnosis

Black Sabbath frontman Ozzy Osbourne revealed Tuesday that he has been diagnosed with Parkinson's disease following a private battle with the neurodegenerative disorder.

In an exclusive interview with Robin Roberts on "Good Morning America," Osbourne, alongside wife and manager Sharon Osbourne, said he was first diagnosed with the disease last February after experiencing a fall while performing at a New Year's Eve show.

"It's been terribly challenging for us all," Osbourne told Roberts. "I did my last show New Year's Eve at The Forum. Then I had a bad fall. I had to have surgery on my neck, which screwed all my nerves."

Parkinson's disease is a long-term neurodegenerative disorder that affects movement, often including tremors. It progresses slowly in most people but currently has no cure.

According to the Centers for Disease Control and Prevention, it is the second most common neurodegenerative disease after Alzheimer's disease, and the Parkinson's Foundation estimates that approximately 60,000 Americans are diagnosed with the condition each year.

Sharon Osbourne maintained that the diagnosis will not hold the rocker back, adding that they plan to seek further medical advice in Switzerland after exploring various options in the United States, where they are based.

"It's not a death sentence by any stretch of the imagination," Sharon Osbourne said. "But it does affect certain nerves in your body. It's like you have a good day and then a really bad day."

Before the diagnosis, Osbourne battled rumors about his physical state, even previously denying at one point that he had Parkinson's disease.

But the heavy metal legend said that is all behind him now and he hopes that his fans will support him as he moves forward.

"I just hope they hang in there for me because I need them," Osbourne said.
