A new study suggests a surprising link between musical engagement and cognitive health in older adults. Researchers found that individuals who regularly listened to music experienced a significant reduction in their risk of developing dementia.
The study, conducted by Monash University in Australia, followed over 10,893 Australians aged 70 or older residing in retirement communities. Participants were assessed for dementia diagnoses at the start of the study and monitored for at least three years. They were also asked about their music habits – whether they listened to music frequently and if they played instruments.
The results revealed a compelling connection between music engagement and cognitive well-being:
-
People who consistently listened to music had a 39 percent lower risk of developing dementia compared to those who rarely or never did. They also exhibited a 17 percent reduced likelihood of experiencing milder cognitive impairments. Notably, they performed better on tests measuring general cognitive function and episodic memory – the ability to recall everyday events.
-
Those who regularly played music, such as an instrument, were 35 percent less likely to develop dementia. While this group didn’t show significant improvement in other cognitive areas compared to non-players, it still points towards a protective effect against dementia specifically.
- The most significant benefit appeared for individuals who engaged with both listening and playing music. This combination was linked to a 33 percent reduction in dementia risk and a 22 percent reduction in other cognitive impairments.
Interestingly, education level seemed to influence the strength of these benefits, with higher levels of education (16+ years) correlating with stronger positive effects from music engagement. The researchers note that while this study suggests a strong association, further investigation is needed to establish a definitive cause-and-effect relationship.
“Music activities may be an accessible strategy for maintaining cognitive health in older adults,” explains Emma Jaffa, lead author of the study. However, she emphasizes, “causation cannot be established.”
While we can’t definitively say that listening to music prevents dementia, there is compelling evidence to support its positive impact on brain health. Hearing loss is already recognized as a risk factor for dementia, and research shows hearing aids can mitigate cognitive decline.
As Joanne Ryan, senior author of the study, explains: “Listening to music activates a whole range of regions across your brain, giving you that cognitive stimulation which is beneficial to help reduce your risk of dementia.”
Keeping those favorite tunes playing might just be one more reason to enjoy your music – a potential safeguard for sharper thinking in the years ahead.
