Tau PET Imaging and Cognition


This study will use the new radioactive tracer 18F-MK-6240 in positron emission tomography (PET) scanning to detect tau pathology in older adults who are cognitively healthy and mildly cognitively impaired.

Tau is a protein that accumulates abnormally in the brains of people with Alzheimer's disease and other dementias. In this study researchers will examine the interactions between tau levels and performance on cognitive tasks, functional magnetic resonance imaging neural activation patterns, and other cognitive and behavioral measures. The study also aims to examine how the presence of tau may contribute to the risk of subsequent cognitive decline, neurodegeneration, and dementia.
