Brief summary
This study evaluates the effect of rasagiline on balance in Parkinson's disease. Participants taking study medication which is rasagiline or sugar pill will undergo a computerized balance test on and off medication. Participants will stand on a platform which which moves slightly and a computer will measure their body sway and provide a balance score.
Detailed description
The study will test the hypothesis that therapy with rasagiline improves balance in PD patients as measured by computerized dynamic posturography. 5 subjects will be randomized to rasagiline or placebo and 5 further subjects will be randomized to rasagiline as adjuvant therapy versus placebo. Subjects will be analyzed by computerized dynamic posturography testing. The device measures body sway under varying visual and vestibular cues and is used for assessment of balance
Interventions
Patients in each arm will have computerized dynamic posturography performed at baseline prior to taking first tablet as well as at 4 weeks and 8 weeks. In the adjuvant therapy arm, subjects will be evaluated on rasagiline but in a functional OFF state for their other Parkinson disease medications.
Rasagiline 1 mg oral tablet daily will be administered to study participants.
Placebo 1 mg oral tablet daily will be administered to study participants.

Eligibility
Inclusion criteria
1. 18 years old or above 2. Clinical diagnosis of Parkinson disease by verified by movement disorders expert at the initial study visit with at least two cardinal signs of the disease (rest tremor, bradykinesia, rigidity, and postural instability). 3. For the monotherapy arm, patients must not be on amantadine, dopamine agonists, or levodopa. For the adjuvant therapy arm: Patients must be on a stable dose of their current medication for treatment of Parkinson disease which may include any combination of the following: amantadine, trihexiphenydil, dopamine agonist, and/or levodopa. 4. Patients may continue their stable dose of tricyclic, selective serotonin reuptake inhibitor, or serotonin norepinephrine reuptake inhibitor if they are on these medications at randomization.
Exclusion criteria
1. Catechol-O-Methyltransferase (COMT) inhibitor therapy use 30 days prior to start of study (both study arms). 2. Dopamine receptor blocker use (such as quetiapine) one week prior to taking study drug 3. For both monotherapy and adjuvant therapy arms: use of MAO inhibitor therapy including selegiline or rasagiline within 30 days prior to taking study drug and first posturography evaluation.
