A recent Australian study found that regular music listening and playing are linked to notably lower risks of dementia and milder cognitive decline in older adults, with stronger effects when both activities are combined.
Researchers tracked more than 10,800 adults aged 70 and up over several years and asked about how often they listened to music and played instruments. The study reported that consistent music listeners had a substantially lower chance of developing dementia compared with those who rarely or never engaged with music. Playing an instrument showed similar protective associations, and doing both produced the most pronounced benefits.
Specifically, people who always listened to music showed about a 39% lower risk of dementia, while instrument players had roughly a 35% lower risk. Those engaging in both activities also scored higher on memory tests that measure everyday recall, known as episodic memory. Regular musical involvement was tied to better overall cognitive scores during the study period.
The protective effect extended beyond dementia to milder cognitive problems too, with regular music engagement linked to a 22% reduced risk of mild cognitive impairment. That suggests music might help with early-stage cognitive struggles as well as more severe decline. The results add to a body of evidence that mentally engaging hobbies can influence brain health as we age.
“With no cure currently available for dementia, the importance of identifying strategies to help prevent or delay onset of the disease is critical,” Ryan said in a statement. “Evidence suggests that brain aging is not just based on age and genetics but can be influenced by one’s own environmental and lifestyle choices,” she added.
The study also found differences by education level: the benefits of music were most noticeable among participants with higher education, defined as at least 16 years of schooling. Results were less uniform for those with moderate levels of education, which raises questions about how social and cognitive reserves interact with leisure activities. That pattern means context matters when interpreting the protective links.
Scientists cautioned that the study shows association, not proof of cause and effect, and stressed the need for further research to untangle whether music directly prevents cognitive decline. “Music activities may be an accessible strategy for maintaining cognitive health in older adults, though causation cannot be established,” the researchers noted. Observational studies like this are useful for spotting promising habits but fall short of definitive answers.
Outside experts urged a balanced reading of the findings, pointing out the broader benefits of learning and social activities. “In general, it is advised to train your brain, but the data is actually not that clear,” one specialist commented, noting mixed results across studies of music, puzzles, and new skills. He also highlighted noncognitive perks of musical life.
“There are additional benefits to playing an instrument … including increased social interactions — which has been shown to be very important as we age.” Social connection, group rehearsal, and shared concerts can all reinforce mental stimulation in ways that solo activities might not. Those combined social and cognitive advantages could help explain why music appears protective in many aging studies.
The takeaway for older adults is practical: music is low-cost, widely accessible, and enjoyable, so trying it carries few downsides. Whether through listening playlists, community choirs, or picking up a simple instrument, adding musical moments to daily life can be a pleasant way to support brain engagement. While not a guaranteed prevention, music looks like a promising piece of a larger lifestyle approach to healthy aging.
