Neuroimaging may shed light on how Alzheimer's disease develops

Current Alzheimer's disease research indicates that accumulation of amyloid-beta (AB) protein plaques in the brain is central to the development of AD. While previously presence of these plaques could only be confirmed at autopsy. Positron emission tomography provides researchers with an opportunity to test the amyloid hypothesis as it occurs in living patients. A new study summarizes the results of experiments using the AB tracer Pittsburgh Compound-B.
