Mindfulness disposition is linked to stronger brain connectivity in older adults. This trait enhances the default-mode network (DMN), crucial for internal thought and emotional control.
Area of Science:
- Neuroscience
- Cognitive Psychology
- Aging Research
Background:
- The default-mode network (DMN) is vital for internal mentation and shows altered connectivity with aging.
- Reduced DMN connectivity in older adults is associated with functional declines.
Purpose of the Study:
- To investigate the relationship between DMN integrity and trait mindfulness in older adults.
- To determine if mindfulness disposition influences DMN connectivity in the elderly.
Main Methods:
- Functional magnetic resonance imaging (fMRI) was used to assess DMN connectivity.
- Questionnaires measured mindfulness disposition and overall health in 25 older adults.
Main Results:
- Mindfulness disposition was positively associated with DMN connectivity.
- Specific increases in connectivity were observed in the dorsal posterior cingulate cortex and precuneus.
Conclusions:
- Mindfulness disposition explains variance in DMN connectivity among older adults.
- Enhanced DMN connectivity through mindfulness may support cognitive and affective control in aging.
