How Parkinson's disease (PD) impacts people’s lives

More than 1 million people in the U.S. and an estimated 4 to 6 million people worldwide suffer from PD. The European Parkinson's disease Association estimates that 1.2 million people have PD in the European Union. 

PD is a chronic, progressive neurodegenerative disease characterized by motor symptoms, including tremor at rest, rigidity and impaired movement, as well as significant non-motor symptoms, including cognitive impairment and mood disorders. It is the second most common neurodegenerative disease behind Alzheimer’s disease, and PD’s prevalence is increasing with the aging of the population.3 OFF episodes are a complication of the disease. Up to 40% of all people with PD whose symptoms are otherwise managed with ongoing drug therapy experience OFF episodes at least once daily and up to six times daily, with each episode typically lasting between 30 and 120 minutes.1,2
