80岁以上的超级Agers显示,由于健康的大脑环境,与可能防止记忆衰减的生活方式因素相关联,大脑细胞增长幅度更大。 SuperAgers over 80 show greater brain cell growth due to healthy brain environments, linked to lifestyle factors that may prevent memory decline.

“自然”的一项新研究发现,由于CA1神经元和天体细胞的扶助性细胞环境,超级Agers — — 超过80岁、记忆超强的人 — — 在河马庄园中生成的年轻神经元远远多于健康老年人或老年痴呆症患者。 A new study in Nature finds that SuperAgers—people over 80 with exceptional memory—produce significantly more young neurons in the hippocampus than healthy older adults or those with Alzheimer’s, thanks to a supportive cellular environment involving CA1 neurons and astrocytes. 这种强化的神经发源和合成信号可保持大脑的可塑性和认知功能。 This enhanced neurogenesis and synaptic signaling may preserve brain plasticity and cognitive function. 虽然遗传学可能有所助益,但运动、饮食、睡眠和血管健康等生活方式因素与更好的大脑结构和减少老年痴呆症的标记相关联,从而证明老龄化的大脑可以保持耐受性和适应性。 While genetics may contribute, lifestyle factors like exercise, diet, sleep, and vascular health are linked to better brain structure and reduced Alzheimer’s markers, offering evidence that the aging brain can remain resilient and adaptable.
