Could “musical medicine” influence healthy aging? That is the question that researchers like Psyche Loui, Ph.D., and Julene Johnson, Ph.D., are exploring in their respective studies on the relationship between music and cognitive health. Loui, who leads the Music, Imaging, and Neural Dynamics (MIND) Lab at Northeastern University, focuses on understanding how the brain processes music and how it can potentially improve learning, memory, and emotions. Johnson, a professor at the University of California, San Francisco, investigates the impact of music on overall health and wellness.

Could “musical medicine” influence healthy aging?

Johnson, a professor at the University of California, San Francisco, investigates the impact of music on overall health and wellness.

Both Loui and Johnson have found compelling evidence that suggests music can have a positive effect on aging. Loui's research shows that our brains are wired to predict and anticipate familiar rhythms and melodies. When we listen to music that we've enjoyed throughout our lives, our auditory cortex, the part of the brain that processes sounds, becomes active and communicates with the medial prefrontal cortex, which processes memories about ourselves. This interaction between the auditory system and the medial prefrontal cortex is crucial for learning and memory functions, which tend to decline with age.

To further explore this connection, Loui and her colleagues developed an eight-week mindful music-based listening program for healthy older adults. The participants showed increased functional connectivity between the auditory system and the medial prefrontal cortex, areas that typically become less active as we age. Building on this success, Loui is now testing this intervention in older adults with memory impairments, with the hope that music can help revive their learning and memory functions.

In addition to her work on music and aging, Loui is also involved in a project called the Multimodal Musical Stimulation for Healthy Neurocognitive Aging study. This study focuses on designing and testing a device that pairs music selected by participants with rhythmic, colored LED light patterns. The inspiration for this technology comes from mouse studies where Alzheimer's disease-related brain deposits were reduced through light and sound stimuli. Loui and her team are working on prototypes to test this light and sound intervention as a potential therapy for older adults and individuals with mild cognitive impairment or dementia.

Johnson's research, on the other hand, centers around the impact of community choir participation on healthy aging. Through her Fulbright fellowship in Finland and the Community of Voices study, Johnson has found that participating in a community choir can have various positive effects on older adults. While the research did not show changes in cognitive outcomes, participants reported reduced feelings of loneliness and an increased interest in life. They also noted higher self-esteem, an enhanced sense of finding a place in society, and stronger cultural identity. Furthermore, the singers experienced physical benefits such as improved breath capacity and psychosocial effects like higher assertiveness and confidence in their voice.

The findings of both Loui and Johnson suggest that music has the potential to positively impact healthy aging. So, how can we incorporate music into our lives to reap these benefits? Here are three actionable pieces of advice:

1. Create a personalized playlist: Take some time to curate a playlist of songs that you have enjoyed throughout your life. These familiar tunes can engage your brain's reward systems and help maintain and improve cognitive functions.

2. Join a community music group: Whether it's a choir, a band, or an orchestra, participating in a community music group can provide social connections, reduce feelings of loneliness, and enhance your overall well-being.

3. Explore music-based therapies: Keep an eye out for emerging technologies like the light and sound intervention being developed by Loui and her team. These therapies may offer new ways to improve cognitive functions and enhance the aging process.

In conclusion, the research conducted by Loui and Johnson suggests that music can play a significant role in healthy aging. By understanding how our brains process music and incorporating it into our lives, we can potentially improve learning, memory, and overall well-being. So, why not turn up the volume and let the power of music guide us on our journey to healthy aging?
