Mild Cognitive Impairment Clinical Trial
Official title:
Biodistribution of [11C]Acetoacetate/[18F]Fluorodeoxyglucose in Subjects With Varying Risk Factors for Alzheimer's Disease and Subjects on a Diet Intervention
This is a single center imaging study that will recruit 60 participants who are enrolled in the Effect of a Ketogenic Diet on Alzheimer's Disease Biomarkers and Symptoms: Brain Energy for Amyloid Transformation in AD (BEAT-AD) Study protocol. This cohort of patients will receive a maximum of 3 [11C]Acetoacetate (AcAc)/[18F]Fluorodeoxyglucose (FDG) PET scans over 18 weeks as part of this supplemental trial.
The main objective of this study is to examine the brain biodistribution of [11C]AcAc/[18F]FDG, a proxy for acetoacetate (ketone body)/glucose metabolism in 3 study groups; 1) those without identifiable risk of Alzheimer's disease, 2) asymptomatic individuals with increased risk of Alzheimer's disease (such as pre diabetes),and 3) those with early Alzheimer's disease or MCI. Secondary objectives include determining the association between adipose tissue distribution/function and biomarkers of AD pathology. ;
