Recent research indicates that older adults who play musical instruments tend to have healthier brains.
One investigation examined the impacts of decades of music practice, while another focused on learning new instruments later in life.
In both studies, engaging in music was linked to better brain health and a decrease in age-related cognitive decline.
The first study was published in PLOS Biology and involved collaboration between Canadian and Chinese researchers. They recruited 50 adults with an average age of 65, half of whom had been playing instruments for at least 32 years, while the others had no musical experience.
Additionally, they included 24 young adults with an average age of 23 who had no musical training.
The researchers utilized magnetic resonance imaging (MRI) to assess blood flow in the brains of the participants.
During the scans, participants listened to a recording of speakers amid background noise, where 50 other voices were present, and were tasked with identifying what the main speaker was saying.
The scans revealed that older musicians’ brains responded to challenges similarly to those of the younger participants.
Nonetheless, older adults showed signs of cognitive decline. Specifically, musicians exhibited strong neural connections on the right side of the brain that non-musicians lacked, which could place additional strain on their brain.
“The brains of older musicians remain finely tuned due to years of training, so they don’t need to play well-tuned instruments at high volumes,” stated co-author Dr. Yi from the Chinese Academy of Sciences.
“Our findings suggest that musical experience helps mitigate the additional cognitive strain typically associated with age-related challenges, particularly in noisy environments.”
As individuals age, cognitive functions such as memory, learning, and perception often deteriorate, eventually contributing to dementia.
However, researchers posit that cognitive reserve—the brain’s capability to manage damage and decline—can enhance resilience against this deterioration.
The precise mechanisms remain unclear, as noted by Morten Scheibye-Knudsen, Associate Professor of Aging at the University of Copenhagen, Denmark, in an interview with BBC Science Focus.
Some studies suggest that “exercising” the brain through activities like playing instruments, learning new languages, and solving puzzles can improve brain health, but results from other research have been inconsistent.
“Overall, we advocate for brain training, but the evidence is not conclusive,” Scheibye-Knudsen remarked.
Conversely, another recent study, published in Imaging Neuroscience, indicated that musical practice can enhance brain health, even when individuals start playing in later life.
Researchers at Kyoto University in Japan continued previous studies that included 53 elderly individuals (average age 73) who took music lessons for four months. Initial findings indicated no significant differences in brain health among participants.
Four years later, the same participants underwent MRI scans (13 of whom had maintained their music practice).
Those who ceased playing their newly learned instruments showed declines in memory performance, with a noticeable reduction in the volume of the putamen—a brain region associated with motor function, learning, and memory.
However, those who continued playing music over the four years exhibited no cognitive decline.
Scheibye-Knudsen noted that the study demonstrates that “playing an instrument not only helps preserve cognitive function as we age, but it may also directly contribute to maintaining the structural integrity of the brain.”
He added, “Engaging in music beyond what this study covered offers additional advantages, such as enhanced social interaction.”
“I encourage people to start making music; it’s never too late to learn.”
