About Parkinson's DiseaseOver one million people in the US and an estimated 5 million people globally suffer from Parkinson's disease, a neurodegenerative disorder leading to diminished production of dopamine, a key neurotransmitter, resulting primarily in progressive impairment of motor function characterized by tremors, rigidity and slow movements.About Levodopa-Induced-DyskinesiaLevodopa-induced-dyskinesia occurs in most patients with Parkinson's disease (PD) after several years of treatment, generally in association with other motor response complications, such as wearing-off or "on-off" fluctuations. Dyskinesia may be as disabling as the parkinsonism itself, and current treatment options are limited and are not always effective.
