Fact check: What was Ozzy Osbourne's condition before his death?

1. Summary of the results

Based on the analyses provided, Ozzy Osbourne had Parkinson's disease as his primary medical condition before his death. Multiple sources confirm he was diagnosed with this progressive neurodegenerative disorder, with one source specifically noting he announced his diagnosis about five years before his death ^[1]. Another source indicates he was diagnosed with Parkinson's disease in 2020 ^[2].

The analyses reveal that Osbourne suffered from a rare form of Parkinson's disease ^{[3] [4]} and had been open about his condition for several years before his death ^[3]. Beyond Parkinson's, he experienced various health complications including limited mobility ^[5], a severe upper respiratory infection, and spinal surgeries ^[2]. His condition also affected his voice, with sources noting his ailing voice during his final performances ^[6].

2. Missing context/alternative viewpoints

The original question assumes Ozzy Osbourne's death as a fact, but the analyses don't provide clear confirmation of when or if he actually died. Several sources mention his retirement from touring and farewell tour ^{[7] [8]}, suggesting he may have been transitioning away from live performance due to his health conditions rather than having passed away.

The analyses also reveal important context about his final concert being described as "an emotional display of defiance" ^[6], indicating he continued performing despite his deteriorating health. One source mentions his "biggest fear" in relation to his farewell tour ^[7], though the specific details aren't provided in the analysis.

3. Potential misinformation/bias in the original statement

The original question contains a significant factual assumption by stating "before his death" as if Ozzy Osbourne's death is an established fact. However, the analyses provided don't confirm his death occurred, instead focusing on his health struggles and retirement from touring. This represents a fundamental error in the premise of the question.

The question also lacks specificity about what type of "condition" is being asked about - whether medical, physical, mental, or general health status. The analyses primarily focus on his Parkinson's disease diagnosis and related health complications, but don't provide a comprehensive picture of his overall condition in his final period of public activity.
