|Mild Cognitive Impairment Aging||Drug: 18F-MK-6240|
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.
|Study Type :||Observational|
|Estimated Enrollment :||65 participants|
|Official Title:||Tau Positron Emission Tomography (PET) in Imaging and Cognition|
|Actual Study Start Date :||June 1, 2018|
|Estimated Primary Completion Date :||January 2023|
|Estimated Study Completion Date :||December 2023|
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.
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
- 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.
