The Protective Role of Flavonoid in Amnesia Final- Manscript.docx

Flavonoids, a diverse group of plant-derived polyphenolic compounds, have garnered considerable attention for their neuroprotective properties, particularly in relation to cognitive impairment and memory loss. This systematic review explores the current body of evidence on the role of flavonoids in preventing or mitigating amnesia. Drawing from preclinical and clinical studies, the review highlights the mechanisms by which flavonoids exert their protective effects, including antioxidant activity, anti-inflammatory action, modulation of signaling pathways such as ERK and PI3K/Akt, and enhancement of synaptic plasticity. The review also discusses specific flavonoid subclasses—such as flavonols, flavanones, and anthocyanins—and their sources, including fruits, vegetables, and medicinal herbs. Findings suggest that regular intake of flavonoid-rich foods or supplements may improve memory retention and reduce the progression of neurodegenerative disorders like Alzheimer’s disease. However, the review emphasizes the need for well-designed human trials to confirm these benefits and to determine optimal dosing strategies. Overall, this work consolidates the current scientific understanding of flavonoids as promising agents in the prevention and management of amnesia.

黄酮类化合物（Flavonoids）是一类结构多样的植物来源多酚类复合物，因其神经保护特性受到广泛关注，尤其与认知障碍及记忆丧失密切相关。本系统综述梳理了当前关于黄酮类化合物预防或缓解失忆症的证据体系。本综述结合临床前与临床研究，阐明了黄酮类化合物发挥保护作用的潜在机制，包括抗氧化活性、抗炎作用、对ERK及PI3K/Akt等信号通路的调控，以及对突触可塑性的增强作用。综述还讨论了特定黄酮类亚类——如黄酮醇（flavonols）、黄烷酮（flavanones）和花青素（anthocyanins）——及其食物来源，涵盖水果、蔬菜与药用草本植物。研究结果表明，定期摄入富含黄酮类化合物的食物或补充剂，或可改善记忆保留能力，并延缓阿尔茨海默病（Alzheimer’s disease）等神经退行性疾病的进展。不过，本综述强调仍需开展设计严谨的人体试验，以证实上述益处并确定最佳给药策略。总体而言，本研究整合了当前关于黄酮类化合物作为预防与管理失忆症潜在有效手段的科学认知。
