Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Experimental F 18 T807
Participants will undergo a PET scan using the flortaucipir imaging tracer
F 18 T807
Participants will receive a single intravenous bolus injection of approximately 6.5-10mCi (240-370MBq) of F 18 T807. For those who cannot tolerate the full exam, participants will receive single intravenous bolus injection of approximately 6.5-10mCi (240-370MBq) of F 18 T807.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
2. Cognitively normal, or with mild dementia, as assessed clinically
3. Participant is able and willing to undergo testing (MRI or CT, PET, radioactive tracer injection, LP; for those unable to undergo an MRI, CT will be used to generate regions-of-interest).
4. Pre-menopausal women will undergo a urine pregnancy test within 24 hours of drug administration.
Exclusion Criteria
2. Is deemed likely unable to perform the imaging procedures for any reason.
3. Has a high risk for Torsades de Pointes or is taking medications known to prolong QT interval.
4. Has hypersensitivity to F 18 T807 or any of its excipients.
5. Contraindications to PET, PET-CT or MR (e.g. electronic medical devices, inability to lie still for long periods) that make it unsafe for the individual to participate.
6. Severe claustrophobia.
7. Currently pregnant or breast-feeding.
8. For those electing to undergo the optional lumbar puncture: currently on anticoagulant of any form -
