The incidence and prevalence of neurodegenerative disorders (e.g., Alzheimer’s disease (AD), Parkinson’s disease (PD), and Huntington’s disease (HD), etc.) are growing rapidly due to increasing life expectancy. Researchers over the past two decades have focused their efforts on the development of animal models to dissect the molecular mechanisms underlying neurodegenerative disorders. Existing models, however, do not fully replicate the symptomatic and pathological features of human diseases. This chapter focuses on animal models of AD, as this disorder is the most prevalent of the brain degenerative conditions afflicting society. In particular, it briefly discusses the current leading animal models, the translational relevance of the preclinical studies using such models, and the limitations and shortcomings of using animals to model human disease. It concludes with a discussion of potential means to improve future models to better recapitulate human conditions.
