Brain Tests For OZZY?

Britain's Daily Record is reporting in its October 15 online edition that OZZY OSBOURNE is undergoing tests for Parkinson's disease.

The ex-BLACK SABBATH frontman has been seen shaking throughout the MTV hit reality show "The Osbournes".

Former heavy-duty drug abuser Ozzy, 54, is allegedly having checks for the brain disease in a Boston hospital. A source told the paper: "He's worried about his shaking and wants to know what's causing it."
