Brief Summary
This is a cross-sectional pilot study of Alzheimer's disease (AD) brain imaging biomarkers in Diabetes Prevention Program (DPP) outcomes study (DPPOS) participants from the New York City sites (Columbia and Einstein), comparing 10 persons originally randomized to metformin and 10 persons randomized to placebo in DPP. All study procedures will be conducted at Columbia University Irving Medical Center. Eligible participants will receive a PET scans and a brain MRI, which may be conducted in one, two, or three separate visits.

Up to 1 hour post-injection
Brain Tau SUVR
Tau (18F-MK-6240) SUVR in medial and inferior temporal lobes
Up to 1 hour post-injection

Study Arms (2)
DPPOS Exposed to Metformin
EXPERIMENTALDPPOS participants with exposure to metformin will be scanned with 18F-MK-6240 and 11C-PIB.
DPPOS Exposed to Placebo
ACTIVE COMPARATORDPPOS participants with no exposure to metformin but only placebo will be scanned with 18F-MK-6240 and 11C-PIB.
Interventions
This radiotracer will be used to detect Tau.The injected activity will equal 5 millicuries (mCi).
This radiotracer will be used to detect amyloid. Participants will be injected with an intravenous bolus of up to 5-15 mCi.
