Brief Summary:
The investigators aim to use the new PET radioligand, 18F-MK-6240, to detect tau pathology in cognitive healthy and mild cognitive impairment (MCI) elders. The investigators will then examine the interactions between differential tau burden and performance on cognitive tasks, functional magnetic resonance imaging (fMRI) neural activation patterns, and other cognitive and behavioral measures. By investigating these relationships, the investigators hope to understand the cognitive and behavioral outcomes of tau deposition found in specific brain regions in cognitively normal/mildly cognitively impaired adults. Furthermore, the study aims to examine how the presence of tau may contribute to the risk of subsequent cognitive decline, neurodegeneration, and dementia.

Condition or disease Intervention/treatment
Mild Cognitive Impairment Aging Drug: 18F-MK-6240

Detailed Description:

Many cognitively healthy older adults have, upon post mortem evaluations, been found to have varying amounts of neurofibrillary tangles (tau) and beta-amyloid plaque deposits, which are the hallmark brain pathologies known to be associated with Alzheimer's disease and various other dementias. While some with these pathologies may not clinically express cognitive decline or dementia in their lifetime, human post-mortem studies suggest that increasing neurofibrillary tangle density correlates with neurodegeneration and cognitive impairment.

Imaging tauopathy in-vivo provides an opportunity to examine neurocognitive correlates of differential levels of tauopathy in the brain, allowing to further qualify pre-clinical states of cognitive impairment. The investigators aim to investigate possible protective mechanisms, such as cognitive reserve, that may modulate the relationship between tauopathy and cognitive decline.

Group/Cohort Intervention/treatment
Non-demented elders
Participants aged 55-90 that are cognitively normal or have mild cognitive impairment will receive 18F-MK-6240 to identify the presence of tau protein in the brain.
Drug: 18F-MK-6240
Results of the 18F-MK-6240 PET scan will be correlated with other observations.
Other Name: 6-[18F]Fluoro-3-(1H-pyrrolo[2,3-c]pyridin-1-yl)isoquinolin-5-amine

Primary Outcome Measures :
  1. Total number of individuals with tau present [ Time Frame: Up to 5 years ]
    Based on the scans, the total number of subjects with identifiable tau in their scans will be measured.

  2. Cognition [ Time Frame: Up to 5 years ]
    Relation of Tau PET to measures of cognition such as memory and reasoning

  3. Functional imaging (fMRI) [ Time Frame: Up to 5 years ]
    Relation of Tau PET to imaging acquired during task performance

Biospecimen Retention:   Samples With DNA
Plasma, serum and cells will be retained
