Parkinson's disease is a complex neurodegenerative disease characterized by degeneration of dopaminergic neurons of the substantia nigra and the presence of Lewy bodies and Lewy neurites. Between 1990 and 2015, the prevalence of Parkinson's disease more than doubled, and 6.2 million individuals are currently affected by the disease. Moreover, population forecasts suggest that up to 14.2 million individuals will be diagnosed with Parkinson's disease by 2040. The disease causes progressive disability, which can be slowed but not entirely stopped by treatment. Timely diagnosis is important for improving outcomes in patients with Parkinson's disease. Often, nonmotor symptoms precede motor symptoms early in the disease course.
