许多研究已经证明了正常的年龄相关的神经结构，功能和认知能力的下降。初步证据表明，冥想可以减少特定认知领域和大脑结构的下降。在这里，我们扩展了这项研究，调查年龄和流体智力和静息状态脑功能网络架构之间的关系，使用图论，在中年瑜伽和冥想练习者，并匹配控制。瑜伽练习者和冥想者的流体智力下降速度比对照组慢。瑜伽练习者和冥想者的静息状态功能网络相结合，比对照组更完整，更能抵御损伤。此外，正念与流体智力，弹性和全球网络效率呈正相关。这些发现揭示了增加弹性和减缓流体智力和大脑功能结构下降的可能性，并表明正念在这种保护中起着机械作用。
Numerous studies have documented the normal age-related decline of neural structure, function, and cognitive performance. Preliminary evidence suggests that meditation may reduce decline in specific cognitive domains and in brain structure. Here we extended this research by investigating the relation between age and fluid intelligence and resting state brain functional network architecture using graph theory, in middle-aged yoga and meditation practitioners, and matched controls. Fluid intelligence declined slower in yoga practitioners and meditators combined than in controls. Resting state functional networks of yoga practitioners and meditators combined were more integrated and more resilient to damage than those of controls. Furthermore, mindfulness was positively correlated with fluid intelligence, resilience, and global network efficiency. These findings reveal the possibility to increase resilience and to slow the decline of fluid intelligence and brain functional architecture and suggest that mindfulness plays a mechanistic role in this preservation.
