Exclusion Criteria for all groups: Participants will be excluded from enrollment if they meet any of the following criteria.
1. The participant has any medical or psychiatric conditions that, in the opinion of the investigator, would compromise the participant's safety or successful participation in the study.
2. The investigators of UNICORN (IRB #842873) have determined the participant has evidence of structural abnormalities such as major stroke or mass on MRI scan within \< 6 months prior to enrollment that is likely to interfere with analysis of the PET scan.
3. The participant is unable to tolerate or have a contraindication to imaging procedures in the opinion of an investigator.
4. Females who are pregnant or breast feeding at the time of the baseline PET/CT scan will not be eligible for this study. A urine pregnancy test will be performed in women of child-bearing potential at screening and within 24 hours of any scheduled PET/CT.
5. The participant has a history of significant past or ongoing alcohol abuse or substance abuse, or dependence based on medical record review or self-reported (may be excluded at the discretion of the investigator.)
6. The participant is enrolled in a clinical trial for a disease-modifying treatment that targets the molecular pathology underlying their neurodegenerative disease.
