Confirmation from imaging core that screening dopamine transporter SPECT scan is read as eligible (see below). About 80 subjects will have a range of DAT deficit similar to subjects with early PD (mild to moderate DAT deficit). About 20 subjects will be selected with no DAT deficit or minimal DAT deficit similar in age, gender, and risk profile to those with mild to moderate DAT deficit. 4.2.7.3.

Willing and able to comply with scheduled visits, required study procedures and laboratory tests. 4.2.7.5. Women may not be pregnant, lactating or planning pregnancy during the course of the study. Includes a negative urine pregnancy test on day of screening scan prior to injection (DaTSCAN).

Exclusion Criteria (Prodromal Subjects)

1. Current or active clinically significant neurological disorder or psychiatric disorder (in the opinion of the Investigator).
2. GDS score greater than or equal to 10 (GDS score of 5 - 9 requires Investigator discretion to enter study).
3. STAI Form Y-1 greater than or equal to 54 requires Investigator discretion to enter study.
4. A clinical diagnosis of dementia63 as determined by the investigator (Appendix 1).
5. A clinical diagnosis of Parkinson disease at the Screening visit as determined by the Investigator.
