Amyloid PET scans provide in-vivo evidence of Alzheimer’s disease (AD) pathology. However, due to their high cost and limited insurance coverage, they are not widely used in clinical settings outside of the VA Healthcare System. A special form of electroencephalograms (a test that measures electrical activity in the brain) referred to as event-related potentials (ERPs), measures electrical activity that reflects both sensory and cognitive responses to stimuli.
