Tau PET in Imaging and Cognition: Healthy Adults From 55-90
This study uses a brain scan tracer called 18F-MK-6240 to look for tau, a protein that builds up in Alzheimer's, in healthy older adults and people with mild cognitive impairment. Researchers will compare tau levels with memory tests and brain activity scans. The phase is unspecified. It is an imaging study, not a test of a treatment.
