Summary
AI-generated from the abstractFluid intelligence declines slower in middle-aged yoga and meditation practitioners than in matched controls. Resting state functional brain networks of practitioners are more integrated and resilient to damage. Mindfulness correlates positively with fluid intelligence, network resilience, and global network efficiency. The findings suggest that mindfulness may play a mechanistic role in preserving cognitive and brain function during aging.

Abstract
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.
