A recent review by Hermundur Sigmundsson, Ph.D., a professor of psychology at the Norwegian University of Science and Technology, delves into the interplay between passion, physical activity, and social engagement, suggesting these factors might hold the key to cognitive health. The article indicates that these elements could provide protection against cognitive decline, which often manifests as impaired motor function, antisocial behavior, depression, and anhedonia in neurodegenerative and psychiatric disorders, as well as through the natural aging process.
The researchers found compelling evidence that passion, physical activity, and social engagement can buffer against cognitive decline. Physical activity specifically enhances functionality in brain regions associated with attention control and daily life activities. It also contributes to building a cognitive reserve—a mechanism acting as a safeguard against age-related cognitive deterioration.
“The animal literature suggests a number of brain changes associated with physical activity, including new neurons in brain regions that support memory, more connections among neurons (called synapses), and increases in vascular structure. Increases in neurotransmitters and nerve growth factors (among other changes) have also been associated with increases in physical activity in animal models.” – Art Kramer, Ph.D.
Passion is highlighted as a motivational force capable of driving individuals to engage in activities such as learning a second language, thereby strengthening gray matter, neural cells, and connections. Dr. Sigmundsson emphasizes the significance of passion:
“From our research, we have found that passion- or strong interest- may be a key motivational factor for achievement and well-being as it sets the direction of the arrow,” – Hermundur Sigmundsson, Ph.D.
“Therefore, we say: Find your passion and develop it! Grit, or perseverance, is the size and strength of the arrow. Find your interest area and focus on the process. Be ready to take challenges! Challenges are key for development!” – Hermundur Sigmundsson, Ph.D.
Social engagement also plays a critical role in maintaining cognitive health. Dr. Art Kramer from the University of Illinois Urbana-Champaign discussed the research findings with Dr. Sigmundsson. While his exact words were not disclosed, Dr. Kramer contributed insights on how these factors could be personalized for maximum benefit.
“There are a number of limitations, including how best to personalize these factors to enhance cognitive and brain function in individuals as well as how best to combine intellectual engagement, physical activity and social interactions to maximize their benefits across the lifespan and with non-patients and patients alike.” – Dr. Kramer
While the review provides promising insights, it emphasizes the need for intervention studies to further affirm these hypotheses.
