UAB Alzheimer's Disease Center Core Cohort - Imaging Substudy

Summary

The primary objective of this study is to measure the concentration and the regional brain distribution of pathologic amyloid deposition using the PET tracer \[C-11\]PiB in participants in the UAB Alzheimer's Disease Center cohort. Assessment of interactions between race and vascular risk factors, brain amyloid levels measured with \[C-11\]PiB-PET, and cognitive status will be the primary outcome of this imaging study.

Interventions

• [C-11]PiB-PET/MRI · DRUG

  All study participants will undergo brain imaging with \[C-11\]PiB-PET/MRI. \[C-11\]PiB is a PET imaging agent used primarily to measure the amount of abnormal protein (called beta-amyloid) in the brain. The investigator will also use this tracer to evaluate regional cerebral blood flow.

Published eligibility criteria
