The Official Cause of Death: Cardiac Arrest and Chronic Conditions

The official documents released following his passing confirmed the primary cause of the rock legend's death. The final moments were attributed to a catastrophic cardiovascular event, but the full picture involves a cascade of long-term health issues that severely compromised his system over the last two decades of his life.

Primary Cause: Out of Hospital Cardiac Arrest

The immediate and official cause of death was listed as out of hospital cardiac arrest. This event, a sudden cessation of the heart's function, is often the final outcome of severe underlying cardiovascular disease. While the term is definitive, it points to a heart that simply could no longer sustain life, a condition aggravated by years of chronic illness.

Contributing Factors: Coronary Artery Disease and Parkinson's

Crucially, the death certificate listed two significant contributing factors that created the environment for the cardiac arrest: Coronary Artery Disease (CAD) and Parkinson's Disease.

Coronary Artery Disease is a common condition where the major blood vessels that supply the heart with blood, oxygen, and nutrients become damaged or diseased. Over time, this restricts blood flow, significantly increasing the risk of a heart attack or cardiac arrest. Given Osbourne's storied history of lifestyle choices, the presence of severe CAD is a medically recognized, if tragic, contributing factor.

The Long-Term Health Battles: PRKN-2 and Spinal Trauma

To truly understand the circumstances of Ozzy Osbourne's death, one must examine the decade-plus of intense medical challenges that preceded it. His final years were marked by a constant struggle against a rare, genetic neurological disorder and the devastating consequences of a simple fall.

1. The Rare Diagnosis: PRKN-2 Parkinsonism

Ozzy Osbourne was diagnosed with Parkinson's Disease in 2003, though he and his wife, Sharon Osbourne, did not publicly reveal the diagnosis until 2020. His specific condition was identified as a rare, genetic form known as PRKN-2 (Parkin-type Parkinsonism).

PRKN-2 is a form of early-onset Parkinson's linked to a mutation in the *PARK2* gene. While typically slower to progress than other forms, it is a debilitating neurological disorder that causes tremors, rigidity, and difficulty with balance and coordination. The constant battle against this disease was a heavy toll on his physical and mental health, severely limiting his ability to tour and perform in his final years.

2. The Catastrophic 2019 Fall and Spinal Trauma

A pivotal moment in Osbourne's declining health trajectory was a severe fall he suffered in his Los Angeles home in 2019. This accident, which occurred while he was getting into bed, aggravated injuries from a near-fatal ATV accident in 2003.

The fall dislodged metal rods that had been surgically placed in his body after the 2003 accident. This resulted in significant spinal and neck damage, plunging him into a cycle of chronic, debilitating pain and multiple corrective procedures. Over the next few years, the Prince of Darkness underwent at least four major spinal surgeries to correct the damage. His son, Jack Osbourne, and daughter, Aimée Osbourne, often spoke about the constant pain their father endured, which was separate from his Parkinson's symptoms but compounded his overall frailty.

3. The Vicious Cycle of Immobility and Frailty

The combination of PRKN-2 and the spinal trauma created a vicious cycle of immobility. The Parkinson's made movement difficult, and the surgical recovery made it excruciating. This prolonged period of reduced mobility is a high-risk factor for older adults, contributing to muscle atrophy, general frailty, and, critically, placing an increased strain on the cardiovascular system. This physical decline is considered a major factor that accelerated the progression toward the eventual cardiac arrest.

The Final Weeks and Lasting Legacy

Despite his health struggles, Ozzy Osbourne remained determined to reconnect with his fans. Just weeks before his death, in early July 2025, he managed to take the stage for an emotional final concert—a farewell show that proved to be his final bow, fulfilling a long-held wish to perform one last time.

Following his passing, the Osbourne family released a statement expressing their immeasurable sadness. The world mourned the loss of a true icon, whose influence stretched across five decades.

His life was celebrated in his hometown of Birmingham, England, with a public funeral procession. Thousands of fans lined the streets, paying tribute as the procession passed over the "Black Sabbath bridge," a poignant nod to the band he co-founded and the city that shaped him. The procession was followed by a smaller, private ceremony for family and close friends.

Ozzy Osbourne’s legacy is not just one of groundbreaking music and stage antics, but also one of incredible resilience in the face of insurmountable health challenges. He was a true survivor, battling addiction, accidents, and chronic disease, until his heart, weakened by Coronary Artery Disease and the compounding effects of PRKN-2, finally gave out. The Prince of Darkness has left the stage, but his thunderous music and indomitable spirit will forever echo through the halls of rock history.
