Brief Summary
Study participants who have been clinically diagnosed with Parkinson disease will receive no treatment, treatment with either levodopa, or treatment with Mirapex for a period of 12 weeks. Over the course of the study subjects will travel to the Institute for Neurodegenerative Disorders (IND) in New Haven, Connecticut for brain imaging.
