Heavy metal rocker Ozzy Osbourne died this week at 76, just weeks after his farewell show and about five years after announcing he had Parkinson's disease.
Here's what to know about the disease:
Parkinson’s is a neurologic disease that robs people of control over their movements. It typically starts with tremors and is characterized by slow movement, a shuffling gait, stiff limbs, balance problems and slurred speech.
About 1 million Americans are living with Parkinson’s, and 10 million people worldwide, the Parkinson’s Foundation. estimates. It usually appears after age 60, although sometimes it can develop before age 50.
The exact cause isn’t known, but Parkinson’s develops when cells that produce one of the brain’s chemical messengers, called dopamine, begin to deteriorate and die.
Dopamine transports signals to parts of the brain that control movement. Parkinson’s symptoms appear after enough dopamine-producing cells die that there’s too little of this neurotransmitter in the brain.
According to the foundation, most experts believe genetic and environmental factors are behind the disease. Dozens of gene mutations linked to Parkinson's have been discovered and genetics account for 10% to 15% of all cases. Other factors suspected of increasing the risk include head injuries, exposure to pesticides and herbicides and where you live.
There is no cure but there are treatments, including medications that affect dopamine levels and a surgically implanted tremor-blocking device. Patients also can benefit from physical and occupational therapy.
Symptoms worsen over time, usually slowly. The severity of symptoms and how quickly they progress varies widely between patients. In advanced cases, people may be unable to walk or care for themselves. They also can suffer from depression as well as memory and thinking problems.
While Parkinson’s itself isn’t considered fatal, people can die from complications of the disease, including lung problems as muscle weakness impedes the ability to cough and to swallow.

BOSTON (AP) — Marat Khusnutdinov and Viktor Arvidsson scored in the first 3:45 of the game, and the Boston Bruins held on to beat the Seattle Kraken 4-2 on Thursday night after raising Zdeno Chara's No. 33 to the rafters.
Mark Kastelic added a short-handed goal in the second period, and Jeremy Swayman stopped 26 shots for Boston, which swept a five-game homestand for the first time since 2019 and won for the seventh time in eight games. David Pastrnak scored an empty-netter with 15 seconds left after the Kraken picked up back-to-back penalties, then pulled the goalie to play five-on-four.
Chandler Stephenson and Eeli Tolvanen scored, and Joey Daccord made 20 saves for the Kraken, who have lost four of their last five games.
The Bruins began the night by honoring Chara, the Hall of Fame defenseman who was the captain of their 2011 Stanley Cup championship team. Hall of Famers Bobby Orr and current Bruins president Cam Neely were among those who took part in the ceremony, which ended with Chara's children raising his number to the TD Garden rafters.
Khusnutdinov took a long pass from Charlie McAvoy, skated in on Daccord and slipped in a backhand to make it 1-0 54 seconds into the game. Less than three minutes later, Arvidsson tried to center the puck to Casey Mittelstadt, but it was deflected into the net by Seattle's Jordan Eberle.
The Kraken called an early timeout, leaving them without one when they might have needed it down two players in the final minute.
After Stephenson made it a one-goal game, Kastelic poked the puck away from Kraken forward Matty Beniers and skated in on Daccord for the short-handed goal that made it 3-1.
The Kraken visit Utah on Saturday.
The Bruins visit Chicago on Saturday.
