Rock legend Ozzy Osbourne announced this morning he’s been diagnosed with Parkinson’s disease, a nervous system disorder that affects movement.

The 71-year-old said during an interview on “Good Morning America” that aired this morning that the diagnosis came after a fall last year.

Osbourne had to cancel tour dates last year because of health troubles. Osbourne said he really wants to get well and get back to performing because he misses his fans.

His wife, Sharon Osbourne, said the diagnosis “was not a death sentence by any stretch of the imagination,” but he had good days and bad days.
