撰文丨王聪 编辑丨王多鱼 排版丨水成文 阿尔茨海默病 （AD） 是最常见的痴呆症类型，其特征是记忆和认知功能逐渐衰退。临床发现表明，细胞外的 β-淀粉样蛋白 （Aβ） 沉积和神经元内的 神经原纤 维缠结 的 形成与阿尔茨海默病 （AD） 病理生理学有关，然而，靶向这些病理特征的治疗方法，却未能阻止或逆转神经退行性病变的过程。 现在，研究人员不再仅仅关注特定的以神经元为中心的特征，而是出现了一种整体观——多种紊乱事件的复杂相互作用导致了阿尔茨海默病中神经级联反应的逐 渐失调。从这个角度来看，在易受损的神经网络中识别并靶向易感节点进行干预，有望为阿尔茨海默病 （AD） 的防治提供新机会。 2025 年 10 月 1 日，中国科学院杭州医学研究所 谭蔚泓 院士/ 邱丽萍 研究员团队在 Nature 子刊 Nature Biomedical Engineering 上发表了题为 ： Targeted clearance of extracellular Tau using aptamer-armed monocytes alleviates neuroinflammation in mice with Alzheim ...

Core Viewpoint - Novo Nordisk's GLP-1 drug, semaglutide, is being tested for its efficacy in treating Alzheimer's disease, with results expected this fall. A successful trial could revolutionize Alzheimer's treatment and potentially add $15 billion in annual sales for the company [1][2]. Group 1: Drug Development and Market Context - Semaglutide has expanded its application from obesity and diabetes to heart and liver diseases, and now Alzheimer's [1]. - The research was prompted by a finding that diabetes patients using GLP-1 drugs had a 20% lower risk of developing dementia compared to other treatments [1]. - UBS analysts estimate a 10% chance of success for Novo Nordisk in the Alzheimer's treatment space, but the potential revenue impact is significant if successful [1][2]. Group 2: Competitive Landscape and Financial Performance - Novo Nordisk has faced growth challenges, leading to two downward revisions of growth forecasts this year due to competition from cheaper alternatives and Eli Lilly's stronger GLP-1 products [2]. - The company's stock price has dropped over 58% in the past 12 months, significantly more than Eli Lilly's 23% decline [2][4]. Group 3: Mechanism of Action and Research Challenges - Semaglutide operates differently from existing Alzheimer's drugs, which primarily target amyloid-beta proteins. It mimics the GLP-1 hormone, potentially reducing inflammation and altering brain glucose metabolism [6]. - The design of the clinical trial poses challenges, as Alzheimer's is known for high failure rates in drug development. The trial will focus on mild patients with detected amyloid proteins [8]. - Even minor positive results could lead to semaglutide being used as a preventive measure for Alzheimer's [8].

Core Viewpoint - The recent study from Harvard Medical School suggests that lithium deficiency in the brain is linked to cognitive decline and the onset of Alzheimer's disease, indicating that lithium supplementation, specifically lithium orotate, may reverse memory loss and restore brain health [2][6][9]. Group 1: Alzheimer's Disease Overview - Alzheimer's disease (AD) accounts for 60%-80% of dementia cases, affecting approximately 10% of individuals over 65 years old [2]. - Current FDA-approved antibody therapies for AD have limited effectiveness and potential severe side effects, highlighting the need for alternative treatments [2]. Group 2: Lithium's Role in Cognitive Health - Historical context shows lithium was once promoted as a mood enhancer and later recognized as a standard treatment for bipolar disorder, with epidemiological studies suggesting lower dementia rates in areas with trace lithium in drinking water [5]. - The recent study confirms that lithium is naturally present in the brain and plays a crucial physiological role, with lower lithium levels found in areas affected by Alzheimer's compared to unaffected regions [6]. Group 3: Research Findings - The study found that lithium deficiency leads to increased formation of amyloid plaques in mouse models, creating a vicious cycle where lower lithium levels result in more plaque formation, further exacerbating cognitive decline [6][7]. - Lithium orotate was shown to be more effective than lithium carbonate in reversing Alzheimer's-related brain damage and memory loss in mice, potentially explaining inconsistent results in previous clinical trials [6][9]. Group 4: Implications and Future Research - The study did not find toxic effects associated with lithium supplementation, which could simplify future clinical trials for Alzheimer's treatment [9]. - The potential benefits of lithium may extend beyond Alzheimer's, as higher lithium levels were associated with better performance in memory tests among individuals without cognitive impairment [9].
