Brief Summary:
Parkinson's disease (PD) is a neurodegenerative brain disorder that impairs the ability to perform functions such as grooming, dressing, cooking, and other activities of daily living. PD affected between 4.1 and 4.6 million people worldwide in 2005, and it is projected that up to 9.3 million people will be affected by 2030. Although current pharmacological therapies provide beneficial effects on motor symptoms of the disease (tremor, rigidity, and bradykinesia), intolerable disability eventually develops in most patients. A disease-modifying therapy that slows disease progression is a major unmet medical need in PD. Numerous agents have neuroprotective effects in pre-clinical laboratory models, but none have been shown to have indisputable disease-modifying effects in clinical trials for patients with PD.
The purpose of this research study is to investigate how the brain and motor behavior changes in PD over time in response to rasagiline which is a monoamine oxidase-B(MAO-B) inhibitor. The drug rasagiline will be tested in this study as the MAO-B inhibitor. Rasagiline has been prescribed for many years to treat symptomatic Parkinson's disease. It is FDA approved for the treatment of Parkinson's disease but has not been shown to slow disease progression. The outcome and impact of this study will provide the first evaluation of MAO-B inhibitors at slowing the progression of the nigrostriatal pathway using advanced Magnetic Resonance Imaging (MRI) and functional Magnetic Resonance Imaging (fMRI) methods in PD.
Detailed Description:
Participants will receive baseline testing to confirm a diagnosis of Parkinsonism and to determine eligibility in the research study. Half of the participants in this study will be in a group that will receive the study drug (rasagiline), and half will be in a group that will receive a placebo. A placebo is a pill that is made to look like the study drug, but it does not contain any active ingredients. A computer algorithm will randomly decide group assignment (like the flip of a coin). The study drug will be provided at the end of the first visit. The participants will not know which study drug is received, placebo or rasagiline.
During the research study the following test may occur: (1) questionnaires about quality of life and depression; (2) tests to measure strength and motor function; (3) tests to measure cognition; (4) orientation session to learn a precision gripping task; (5) functional MRI scan of the brain; (6) structural MRI scan of the brain.
