Study Arms (2)

depression

All participants will receive two one time PET scans with tracers AV1451 and PIB to detect tau and amyloid in the brain.

Drug: F 18 AV-1451 (Flortaucipir)Drug: [11C]-Pittsburgh Compound B ([11C]PiB)

control

All participants will receive two one time PET scans with tracers AV1451 and PIB to detect tau and amyloid in the brain.

Drug: F 18 AV-1451 (Flortaucipir)Drug: [11C]-Pittsburgh Compound B ([11C]PiB)

Interventions

A dosage range between 6.5 - 10.0 mCi (240-370MBq) is planned for \[18F\] AV-1451. A PET-certified medical professional will prepare and administer the \[18F\] AV-1451tracer. Prior to the administration, the dosage will be assayed in a dose calibrator. The volume of 18F-AV-1451 dose should not be adjusted by adding normal saline to the syringe. Participants will receive a maximum intravenous bolus injection of 10.0 mCi of \[18F\] AV-1451 followed by a 10 mL flush of 0.9% sodium chloride (normal saline).

Also known as: AV-1451
controldepression

A dosage range between 6.0 - 20.0 mCi (222-740 MBq) is planned for \[11C\] PIB. A PET-certified medical professional will prepare and administer the \[11C\] PIB tracer. Prior to the administration, the dosage will be assayed in a dose calibrator and diluted with 0.9% sodium chloride (normal saline) up to a total 20 mL syringe volume. Participants will receive a maximum intravenous bolus injection of 20.0 mCi of \[11C\] PIB followed by a 10 mL 0.9% sodium chloride (normal saline) flush.

Eligibility Criteria

Age65 Years+
Sexall
Age GroupsOlder Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

70 participants will create a depressed cohort in which they must be determined to have active major depressive disorder (MDD) as defined by psychiatrist, Dr. Eric Lenze. 70 participants will be cognitively normal (CDR 0) or cognitively abnormal (CDR 0.5 or 1) but will be considered control cohort.
