Research Progress in Animal Model of Alzheimer's Disease

Abstract

Alzheimer's disease (AD) is one of the most common neurodegenerative diseases, which seriously affects the health of the elderly people. The drugs currently approved for the treatment of AD can only reduce the symptoms severity of AD, but can't cure AD or prevent the deterioration of AD. Over the past 40 years, there have been numerous treatments for AD, including compounds that prevent amyloid deposition in the brain or remove existing amyloid plaques, but their clinical curative effects are not significant. Therefore, more basic and clinical studies are needed to improve our understanding of the biological mechanism of AD. Experimental animal models are very important not only for the study of the pathogenesis of AD, but also for the development of AD drugs. This paper reviewed the main histopathological characteristics, genetic factors, the current animal models and model evaluation of AD.
