Abstract: Alzheimer's disease (AD) is the most common neurodegenerative disease that causes dementia among elderly people. The pathogenesis of AD is still unclear, and currently approved drugs only provide symptomatic benefits and do not prevent or delay progressive neurodegeneration. Meanwhile, potential drugs in development are facing great challenges in clinical translation. Therefore, finding effective treatment for the unmet clinical needs of AD is of great economic value and social significance. In this review, we will summarize the current models and pharmacodynamics evaluation methods of anti-AD drug based on the recent studies at home and abroad, and provide reference for drug development in AD at nonclinical stage.
