Rock legend Ozzy Osbourne, known as the lead singer of Black Sabbath, passed away at 76 on Tuesday after battling a rare type of Parkinson’s disease. He had been candid about his health struggles in recent years, initially discussing his condition during a 2019 appearance on ABC’s “Good Morning America.”
Both Ozzy and his wife, Sharon, revealed that he was diagnosed with Rockstar PRKN-2, a genetic form of Parkinson’s typically associated with a slower progression and earlier onset of symptoms. In his words, “I’m not good at keeping secrets… I can’t hide it anymore.” He recounted experiencing a “bad fall” that required neck surgery and complicated his nerve function.
While he took a break from performing due to health issues, his last public appearance was at Black Sabbath’s “Back to the Of The” show in Birmingham, England, on July 5.
What causes Parkinson’s disease?
Dr. Brandon Crawford, a neurologist from Cedar Park, Texas, notes that Parkinson’s affects individuals differently, largely targeting the midbrain where dopamine, a crucial neurotransmitter, is produced. Dopamine has a significant influence on mood and motor function. Though only about 10% to 15% of cases are purely genetic, most stem from a mix of genetic predispositions and environmental factors.
Dr. Crawford, while not treating Osbourne, explained that substances like toxins, head injuries, sleep disruptions, and inflammation can exacerbate the condition. Symptoms can include tremors, slowed movement, and behavioral changes such as depression and lack of motivation, which highlight how deeply Parkinson’s can impact daily life.
Disease management
Currently, there’s no cure for Parkinson’s, but it can be managed with dopamine agonists and other treatments. Yet, symptoms often return once these medications lose their efficacy. Sharon previously expressed the ups and downs of living with Ozzy’s condition, saying there are “really bad days” followed by better ones.
In 2024, during his SiriusXM show “Ozzy Speaks,” he mentioned undergoing stem cell therapy, and his daughter, Kelly, remarked on his surprising recovery post-treatment, noting improvements in his mobility and strength.
Environmental factors
Experts believe that Ozzy’s heavy metal lifestyle may have contributed to his health challenges, with disruptions to natural circadian rhythms. Staying up late and exposure to artificial light can negatively affect brain function. Additionally, constant loud music and potential long-term exposure to heavy metals, like mercury and lead, typical in rock environments, might also pose risks to health.
In essence, while underlying genetic factors create a foundation for Parkinson’s, lifestyle choices and environmental exposures appear to play a substantial role in its progression. “A lot of elements combine over time,” Dr. Crawford summarized.
