Brief Summary:
The goal of this study is to demonstrate the feasibility of mapping tau pathology in subjects with Primary Progressive Aphasia, using PET protocol with F-AV-1451 (trade name AV-1451) and to systematically document the extent and location of tau pathology in PPA patients in vivo using the same techniques.

Condition or disease Intervention/treatment Phase
