  1. This is a new model, offering a new idea about Alzheimer disease. Maybe we can use a natural pathology to understand the disease in humans.

  2. We need more reports of the neuropathology of aging members of exotic mammalian species. Here is an example that deserves some further investigation as a model of AD. These Chilean "degus" are more closely related to guinea pigs than to lab mice or rats (Huchon and Douzery, 2001).
