Changes to cognitive function during the aging process are related to the brain’s white and gray matter volume. Gray matter consists of biological structures, including neuronal cell bodies, synapses, and capillaries, whereas white matter consists of myelinated axons, through which signals are carried between neurons.
Gray matter volume steadily declines at around 10 years of age. Research suggests that medically and cognitively healthier individuals experience less brain atrophy than less healthy individuals. They have better overall health, which contributes to this difference.
Studies also show that regular exercise, strong relationships, and passion are key to maintaining a healthy brain during the aging process. The researchers found that these factors are crucial for brain health, and it is essential to incorporate them into daily life.
In a recent paper, the researchers performed a thorough review of the extensive body of literature available on the link between brain physiology development, and physical activity, social relationships, and passion. The report indicates that increased passion for an area or skill leads to more physical activity, more social relationships, and better well-being.
Hermundur Sigmundsson, Ph.D., professor of psychology at the Norwegian University of Science and Technology, the lead author, stated that passion may be a key motivational factor for achievement and well-being. He emphasized the importance of finding one’s passion and developing it, as it sets the direction for achievement and well-being.
Exercise and Brain Health
Observational studies indicate that an active lifestyle is helpful for maintaining cognitive and neurological health across age groups — especially in higher order processes such as switching between tasks, working memory, and cognitive inhibition. This is evident in the fact that older adults who underwent 1 hour of aerobic training 3 times per week for 6 months had increased gray and white matter volume compared to controls, which can be linked to brain health benefits.
Other research shows that physical activity increases functionality in brain areas linked to attention and attention control, daily life activities, and cognitive reserve, a reserve of thinking abilities that acts as a buffer against age-related cognitive decline. The team found that physical activity has a positive impact on cognitive function and overall brain health.
Social Interactions and Brain Health
The researchers noted in their paper that intervention studies had confirmed these findings, and that maintaining social ties enhances cognitive reserve through cognitive strategies, greater neural growth, and synaptic density, which protect against pathological processes. It is essential to maintain social interactions to support brain health, as they have a positive impact on cognitive function.
Imaging studies have demonstrated that larger social networks are linked to a larger orbitofrontal cortex — involved in decision-making — and amygdala volume. The researchers concluded that social interactions are vital for maintaining brain health and cognitive function.
Passion and Brain Health
The researchers defined passion as “a strong feeling toward a personally important value/preference that motivates intentions and behaviors to express that value/preference.” They found that passion is related to more deliberate practice and better well-being, which can be beneficial for overall health, including liver health and other organs.
According to the report, passion might be important for maintaining neural plasticity. The researchers emphasized the need for further studies to fully understand the relationship between passion, physical activity, and social interactions and their impact on brain health.
More research is needed to fully understand the relationship between these factors and brain health, but the current evidence suggests that incorporating physical exercise, social interactions, and passion into daily life may have a positive impact on cognitive function and overall brain health.
