There is no animal good model for Alzheimers. You raise a very good point which is almost all the animal models we have are terrible models for human disease that is supposedly being studied. Cancer models of cancer are just as bad. Interestingly the only good model of human cancer are spontaneous cancers in human pet dogs [1]. Of course we hardly use this models despite most dog owners being willing to volunteer their pets for study. 1. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3130881/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3130881/
