Healthy test subjects with amyloid plaque were also found to have hypometabolism indicating a potential Alzheimer’s precursor

Alzheimer’s disease has been linked in many studies to amyloid plaque buildup in the brain, but new research is finding a common thread between amyloid burden and lower energy levels, or metabolism, of neurons in certain areas of the brain associated with Alzheimer’s disease—even for people with no sign of cognitive decline. This is a new development in the understanding of Alzheimer’s pathology, say neuroscientists unveiling the research at the Society of Nuclear Medicine and Molecular Imaging’s 2013 Annual Meeting.
