April 30, 2013, Kathy Fay Mahdoubi reported in Molecular Imaging how research using PET imaging is helping to better understand how neural networks compensate for Alzheimer’s Disease.  “While verbal memory decline associated with Alzheimer’s disease has been well documented, a similarly relevant area of research has gone relatively uncharted until now. Those affected by the neurodegenerative disease also suffer loss of nonverbal memory function and researchers are mapping the effects of Alzheimer’s disease on brain regions dedicated to this area of cognition and finding newly blazed trails of neural activity, according to a study published April 26 in Neurology.”
