NCT07758660

Brief Summary

The purpose of this study is to further engage and characterize Alzheimer's Disease Research Center (ADRC) participants through additional research opportunities, particularly PET imaging. Amyloid and Tau PET imaging will be collected in 24 participants per year, for a total of 120 participants over five years. All participants will be followed longitudinally, including through potential transitions from normal aging to mild cognitive impairment (MCI) and Alzheimer's disease and related dementias (ADRD).

Outcome Measures

Primary Outcomes (2)

  • 18F-FBB Standardized Uptake Value Ratio

    The standardized uptake value ratio is the concentration of radioactivity measured from the 18F-FBB PET scan in the cortex compared to the uptake in the cerebellum (pseudo-reference region).

    Up to 12 months

  • 18F-MK6240 Standardized Uptake Value Ratio

    The standardized uptake value ratio is the concentration of radioactivity measured from the 18F-MK6240 PET scan in the cortex compared to the uptake in the cerebellum (pseudo-reference region).

    Up to 12 months

Study Arms (2)

Cognitive impairment

EXPERIMENTAL

Participants with Alzheimer's disease and related disorders, including but not limited to: Frontotemporal dementia, Lewy Body dementia, Creutzfeldt-Jakob disease, other dementias, and subjective or objective features of mild cognitive change.

Drug: 18F-MK6240Drug: 18F-Florbetaben (FBB)

No cognitive impairment

ACTIVE COMPARATOR

Healthy elderly controls and nonpatient volunteers with subjective or objective features of normal aging.

Drug: 18F-MK6240Drug: 18F-Florbetaben (FBB)

Interventions

MK-6240 is experimental but has been used in several human studies before and has been proven to accurately measure tau in the brain.

Also known as: [18F-MK6240]
Cognitive impairmentNo cognitive impairment

Florbetaben has been approved by the FDA to help diagnose Alzheimer's disease. Florbetaben measures amyloid in the brain.

Also known as: [18F] Florbetaben
Cognitive impairmentNo cognitive impairment

Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Enrolled in the Alzheimer's Disease Resource Center (ADRC)
  • With or without memory problems or impairment
  • Able to participate in all scheduled evaluations and to complete all required tests and procedures in either English or Spanish.
  • In the opinion of the PI, the participant must be considered likely to comply with the study protocol and to have a high probability of completing the study.

You may not qualify if:

  • Conditions precluding entry into the scanners (e.g., morbid obesity, claustrophobia, etc.)
  • Pregnant and/or breastfeeding
  • In the opinion of the PI, the subject has been determined unlikely to complete all procedures.
