Parkinson's disease develops due to the slow depletion of dopamine-producing neurons in a part of the brain called the substantia nigra.

This region of the brain plays an important role in movement, so symptoms include shaking, tremor, and rigidity.

Some believe that we are approaching a Parkinson's pandemic; globally, between 1990–2015, the number of Parkinson's cases has doubled to more than 6 million.

Some predict the number to double again to 12 million by 2040.

Although researchers have studied the disease for decades, they still have many questions about how and why brain cells are destroyed.
