FDG-PET and Brain Insulin Resistance in Parkinson's Disease

Condition


Study Name

FDG-PET as a Biomarker for Brain Insulin Resistance in Parkinson's Disease and the Impact of Liraglutide (IRB no. 47518)


Summary

This study aims to determine the effects of a drug called liraglutide on brain glucose metabolism in Parkinson’s disease (PD) patients. The study focuses on patients diagnosed with idiopathic PD who have already agreed to participate in another study, Liraglutide in Parkinson's Disease. Researchers will utilize imaging techniques to monitor changes in glucose metabolism (the way the brain uses energy) as a result of liraglutide use in PD. A brain imaging procedure, fluorodeoxyglucose-positron emission tomography (FDG-PET) scan, will also enable researchers to better understand glucose metabolism in patients with insulin resistance and Parkinson’s disease. The use of liraglutide in this study is investigational.
