Abstract: Recent studies have found that cognitive impairment caused by Alzheimer’s disease (AD) may result from multiple mechanisms acting in concert. This article summaries the pathogenesis of cognitive impairment related to AD, including the β-amyloid hypothesis, Tau protein hypothesis, neuroinflammation hypothesis, synaptic injury, neuronal dysfunction, and neuroplasticity changes, as well as the APOE gene. And further explores the possible origins of the disease and related drug therapeutic targets. Finally, this paper proposes that future efforts need to comprehensively integrate the different pathogenic mechanisms of AD, and a multi-target therapeutic model may be a new direction for the prevention and treatment of AD-related cognitive impairment.    

Key words: cognitive impairment, Alzheimer’s disease, neurodegenerative diseases, therapeutic target
