am_ta.gifImages in the upper row are representative PET examples performed in an Alzheimer’s diasease patient. Those in the bottom row are from the control subject. These transaxial images were taken at the level of the hippocampus, and they show:

  1. decreased glucose metabolic rate in the temporal lobe (middle collumn)
  2. significantly decreased serotonin 1A receptor density as a result of cell loss (right collumn)
  3. increased presence of plaques and neurofibrillary tangles (left collumn)
