Disentangling the Contribution of Tau to Aging, Dementia, and Neurodegeneration

The purpose of this study is to determine the presence of the protein Tau in the brain in a variety of populations, ranging from healthy adults to those diagnosed with a neurodegenerative disease. It will take up to 6 visits to complete this study.  Over the course of these visits, you will be asked to have 1 MRI scan, 1 T807 PET scan, 1 PiB PET scan, 1 fasting blood draw, and 2 cognitive testing sessions. You may also participate in an optional substudy for lumbar puncture.
