Neuroimaging may shed light on how Alzheimer's disease develops

Current Alzheimer's disease (AD) research indicates that accumulation of amyloid-beta (Aß) protein plaques in the brain is central to the development of AD. Unfortunately, presence of these plaques is typically confirmed only at autopsy. In a special issue of the journal Behavioural Neurology, researchers review the evidence that Positron Emission Tomography (PET) can image these plaques during life. This exciting new technique provides researchers with an opportunity to test the amyloid hypothesis as it occurs in living patients. more
