本期AMA节目中，Peter深入探讨了大脑健康，重点关注阿尔茨海默病的诊断、血基生物标志物的重要性，以及APOE基因变异对患病风险的影响。节目还讨论了预防阿尔茨海默病和神经退行性疾病的策略，包括运动、营养补充、血脂管理、脑力游戏、桑拿、口腔健康和听力损失等。Peter详细分析了这些因素对大脑健康的潜在影响，并提供了相关的数据和建议，帮助听众更好地了解和维护大脑健康。

🧠 诊断阿尔茨海默病：Peter首先介绍了阿尔茨海默病的诊断方法，包括临床评估和生物标志物检测。他强调了早期诊断的重要性，以便及时采取干预措施。

🩸 血液生物标志物：节目深入探讨了血液生物标志物在阿尔茨海默病诊断中的作用，特别是C2N测试等。Peter解释了这些生物标志物如何帮助医生更准确地评估患者的病情。

🧬 APOE基因与风险：Peter详细解释了APOE基因的不同变异对阿尔茨海默病风险的影响。他强调了了解个人APOE基因状态的重要性，以便更好地进行风险管理。

🍎 营养与大脑健康：Peter讨论了营养对大脑健康的影响，包括不同饮食方式与阿尔茨海默病发病率的关系。他提到了EPA和DHA、维生素D、B族维生素等补充剂，以及姜黄素、可可黄烷醇和L-苏糖酸镁等补充剂。

🏋️‍♀️ 运动与脑力游戏：Peter探讨了运动对大脑健康的积极影响，并介绍了有效的运动类型和最低有效剂量。此外，他还讨论了脑力游戏对神经退行性疾病的影响。

🧖‍♀️ 桑拿、口腔健康与听力：节目还涉及了桑拿、口腔健康和听力损失与大脑健康的关系。Peter介绍了这些因素对神经退行性疾病的潜在影响，并提供了相关的建议。

In this “Ask Me Anything” (AMA) episode, Peter goes into depth on the topic of brain health, starting with how Alzheimer's disease is diagnosed, the significance of blood-based biomarkers in diagnosis, and what the various APOE gene variants mean in terms of a person's risk of developing Alzheimer's disease. Next, Peter discusses the various strategies for preventing Alzheimer's disease and neurodegeneration. He touches briefly on exercise as a potent tool, but focuses more on lesser-known factors that could impact brain health, such as nutrition supplementation, lipid management, brain games, sauna, oral health, hearing loss, and more.
