Exclusion Criteria

Parkinson Disease (PD) Subjects: 1.Currently taking levodopa, dopamine agonists, MAO-B inhibitors, amantadine or other PD medication. 2.Has taken levodopa, dopamine agonists, MAO-B inhibitors or amantadine within 60 days of Baseline. 3.Has taken levodopa or dopamine agonists prior to Baseline for more than a total of 60 days. 4.Received any of the following drugs that might interfere with DAT imaging: Neuroleptics, metoclopramide, alpha methyldopa, methylphenidate, reserpine, or amphetamine derivative, within 6 months of Screening. 5.Current treatment with anticoagulants (e.g., coumadin, heparin) that might preclude safe completion of the lumbar puncture. 6.Condition that precludes the safe performance of routine lumbar puncture, such as prohibitive lumbar spinal disease, bleeding diathesis, or clinically significant coagulopathy or thrombocytopenia. 7.Use of investigational drugs or devices within 60 days prior to Baseline (dietary supplements taken outside of a clinical trial are not exclusionary,e.g., coenzyme Q10). Healthy Control (HC) Subjects: 1.Current or active neurological disorder. 2.First degree relative with idiopathic PD (parent, sibling, child). 3.MoCA score = 26. 4.Received any of the following drugs that might interfere with DAT imaging: Neuroleptics, metoclopramide, alpha methyldopa, methylphenidate, reserpine, or amphetamine derivative, within 6 months of Screening. 5.Current treatment with anticoagulants (e.g., coumadin, heparin) that might preclude safe completion of the lumbar puncture. 6.Condition that precludes the safe performance of routine lumbar puncture, such as prohibitive lumbar spinal disease, bleeding diathesis, or clinically significant coagulopathy or thrombocytopenia. 7.Use of investigational drugs or devices within 60 days prior to baseline (dietary supplements taken outside of a clinical trial are not exclusionary, e.g., coenzyme Q10).
