  • Melissa Edler, now at Northeast Ohio Medical University and her colleagues have had the rare chance to study 20 brains from older chimpanzees, aged between 37 and 62. The team examined four areas of the chimps' neocortex and hippocampus--brain regions most commonly affected by Alzheimer's in humans. They discovered beta-amyloid plaques and early forms of tau tangles coexisting in 12 of the chimp brains and, as in humans, they saw increasingly larger volumes of plaques in the brains of a more advanced age
