Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The overall goal of the study is to evaluate how research participants in Parkinson Disease studies that include brain imaging with a dopamine transporter ligand choose to receive the imaging data and what is the impact of the imaging data information on the management of their symptoms.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Research participants who previously underwent ß-CIT imaging will be contacted by the staff at IND to enquire whether they would like to receive their ß-CIT scan data. After signing a Research Participant Information and Consent Form, all research participants will be asked to complete a questionnaire prior to receipt of their imaging data. Those research participants requesting imaging data will be sent their data by IND and may review their data with IND (by phone) and/ or with their study investigator. All research participants will be asked to respond to a second questionnaire after receiving their imaging data and to a third study questionnaire approximately six weeks following receipt of their imaging data.
