Researchers from the University of Copenhagen have made a groundbreaking discovery about Parkinson’s disease, revealing that the most common form of the disease may be caused by a problem in how cells manage their energy.
This finding could lead to new ways to treat or even prevent the disease in the future, bringing hope to the 7 to 10 million people worldwide affected by Parkinson’s, the second most common brain disease in older adults and the number one cause of movement problems.
The researchers found that a normal cellular pathway that helps clean up damaged mitochondria becomes blocked. Mitochondria are tiny parts inside cells that produce energy. When they are damaged, the cell is supposed to remove or repair them. But in people with Parkinson’s, this cleanup process doesn’t work properly.
The cause of most cases has been a mystery—until now.
