Lead Sponsor:

Institute for Neurodegenerative Disorders

Conditions:

Parkinson Disease

Eligibility:

All Genders

18-90 years

Phase:

PHASE1

Brief Summary

The purpose of this study is to assess MK-9470 Positron Emission Tomography (PET) imaging as a tool to evaluate the activity of the CB-1 receptor in the brain.

Detailed Description

The underlying goal of this study is to assess MK-9470 PET imaging as a tool to evaluate the activity of the CB-1 receptor in the brain of Parkinson's Disease (PD) research participants.
