Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The primary objectives of this study are to characterize \[18F\]molecular neuroimaging (MNI)-1020, a positron emission tomography (PET) radioligand for imaging tau pathology, to visually and quantitatively assess and compare brain uptake and pharmacokinetics of \[18F\]MNI-1020 in participants with probable Alzheimer's disease (AD) and compare with age matched healthy participants, to evaluate the safety of a single injection of \[18F\]MNI-1020 and to compare the distribution of tau (using \[18F\]MNI-1020) and amyloid beta (using florbetapir) in participants with probable AD.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

All Participants

* Female participants must be documented by medical records or physician's note to be either surgically sterile (by means of hysterectomy, bilateral oophorectomy, or tubal ligation) or post-menopausal for at least 1 year. Male participants and their partners of childbearing potential must commit to the use of two methods of contraception, one of which is a barrier method for male participants for the study duration
* Male participants must not donate sperm during the study and for 3 months after completion

Healthy Participants

* Males and females aged greater than or equal 50 years. Healthy with no clinically relevant finding on physical examination at screening and upon reporting for the \[18F\]molecular neuroimaging (MNI)-1020 imaging visit
* Have screening \[18F\]florbetapir positron emission tomography (PET) imaging demonstrating no significant amyloid binding based on qualitative analysis (visual read)

Alzheimer Disease - Have screening \[18F\]florbetapir or prior amyloid (in the last 12 months) PET imaging demonstrating amyloid binding based on qualitative (visual read)

Exclusion Criteria

All Participants

* Prior participation in other research protocols or clinical care in the last year in addition to the radiation exposure expected from participation in this clinical study, such that radiation exposure exceeds the effective dose of 50 millisievert (mSv), which would be above the acceptable annual limit established by the United States Federal Guidelines
* Unsuitable veins for repeated venipuncture
* Implants such as implanted cardiac pacemakers or defibrillators, insulin pumps, cochlear implants, metallic ocular foreign body, implanted neural stimulators, central nervous system aneurysm clips and other medical implants that have not been certified for MRI, or history of claustrophobia in Magnetic Resonance Imaging (MRI)
