澳大利亚埃迪斯科文大学精准健康中心的研究团队发现，aquaporin-4（AQP4）基因变异与睡眠习惯之间存在相互作用，可能会影响阿尔茨海默病相关的脑部变化。[1]该研究于2026年7月31日发表在《阿尔茨海默病与痴呆症》期刊上，分析了13种常见的AQP4基因变异。[1]
研究团队发现，携带特定AQP4基因变异的个体在睡眠时间较短时，表现出更快的灰质萎缩。[1]研究负责人Dr. Ayeisha Milligan Armstrong指出，"个体携带的AQP4变异在报告睡眠时间短时，显示灰质萎缩更快"。[1]这一发现说明不同基因变异的人对睡眠不足的反应存在差异。Armstrong进一步强调，"这不仅仅是你携带的基因，而是这些基因如何与周围世界相互作用"。[1]
研究人员表示，未来的阿尔茨海默病预防策略需要更加个性化，建议进行融合遗传信息的临床试验，而非直接推荐遗传检测。[1]
Researchers at Australia's Edith Cowan University's Centre for Precision Health have identified a genetic mechanism that explains why poor sleep affects some people's brains more severely than others.[1] The study, published on July 31, 2026, in Alzheimer's & Dementia, examined thirteen common variations of the aquaporin-4 (AQP4) gene and found that individuals carrying specific AQP4 variants experience faster gray matter loss when they report shorter sleep durations.[1]
The research reveals that genetic predisposition and sleep habits work in tandem to influence brain changes associated with Alzheimer's disease. According to Dr. Ayeisha Milligan Armstrong, individuals carrying certain AQP4 variants showed accelerated gray matter shrinkage when reporting short sleep times.[1] Armstrong further noted: "It is not simply the genes you carry, but how these genes interact with your surrounding environment."[1]
Rather than recommending direct genetic screening, researchers suggest conducting clinical trials that incorporate genetic information to develop more personalized interventions for Alzheimer's prevention.[1]
