Osbourne experienced tremors for some years and linked them to his continuous drug misuse. In May 2005, he found out it was actually Parkin syndrome, a genetic condition, the symptoms of which are similar to Parkinson's disease. Osbourne will have to take daily medication for the rest of his life to combat the involuntary shudders associated with the condition. Osbourne has also shown symptoms of mild hearing loss, as depicted in the television show, "The Osbournes", where he often asks his family to repeat what they say. At the TEDMED Conference in October 2010, scientists from Knome joined Osbourne on stage to discuss their analysis of Osbourne's whole genome, which shed light on how the famously hard-living rocker has survived decades of drug misuse.
