Physically independent, ambulatory 4. Hoehn and Yahr score of I-III inclusive. 5. On stable antiparkinsonian medication for at least one month 6. Women of childbearing potential will confirm a negative pregnancy test and must practice effective contraception during the period of pilot study. In addition, male subjects who have a partner of childbearing age should practice effective contraception. Inclusion Criteria for Second Partner with No PD in Couple Pairs in Parkinson's Group 1. No clinical diagnosis of PD 2. Age 25 years old and older 3. Physically independent, ambulatory 4.

Cognitive impairment by evaluation or known score on Mini-Mental Status examination of 25 or lower. 3. Wheelchair-bound or bed-ridden, non-ambulatory. 4. Intracranial abnormalities that may complicate interpretation of the brain scans (e.g., stroke, tumor, vascular abnormality affecting the target area). 5. Diagnosis of traumatic brain injury with significant impairment. 6. Any medical disorder or physical condition that could reasonably be expected to interfere with the assessment of parkinsonian syndrome symptoms, or with any of the study assessments including the PET-MRI imaging. 7.

Subjects with evidence of a significant psychiatric disorder by history/examination that would prevent completion of the study will not be allowed to participate. 9.
