This latter affects 700,000 in the USA, 1.2 million in Europe and 6.3 million people worldwide(1).
It is the second most-frequent neurodegenerative disorder after Alzheimer's disease.

The disease's chronic effects are due to the progressive breakdown of certain nerve cells in the brain.
The efficacy of the most frequently used treatments diminishes over time. When that occurs, patients may start experiencing "off episodes", that is, a period when the symptoms of difficult or impossible ("freezing") movement return.
