What is the A05 Study?

This is a cross-sectional and longitudinal study that to evaluate imaging characteristics of 18F-AV-1451 in cognitively healthy volunteers, mild cognitive impairment (MCI) and Alzheimer's disease (AD) subjects.

What is the Purpose of A16?

Tau is a protein that accumulates, forming “tangles” within the brains of patients with Alzheimer’s disease. The tangles damage the way brain cells are able to communicate which eventually leads to death of these cells. Until recently, researchers were unable to determine tau accumulation in the brains of living people. With the development of new PET scan technology using the radioactive tracer 18F-AV-1451, researchers are now able to see tau in the living brain.


The study is ongoing at the Memory and Aging Clinic at Butler Hospital, but is no longer enrolling subjects.
