Listening to music most days could guard against dementia, study suggests

Music may be more powerful for the ageing brain than we realise. A large Australian study has found that older adults who regularly listen to or play music are far less likely to develop dementia. The findings, drawn from more than ten thousand people over the age of seventy, suggest that keeping music in your life could be a simple way to help protect your memory and thinking as you age. The research was part of the ASPREE project, which follows healthy older adults over many years. None of the participants had dementia when the study began. They were asked how often they listened to music or played an instrument, and their thinking skills were tested over time. After several years, the researchers looked at who had gone on to develop dementia or mild cognitive problems. Those who said they always listened to music had around a forty percent lower risk of developing dementia compared to those who rarely or never did. Regular music listeners also showed a modestly lower risk of general cognitive decline. People who played an instrument often or always enjoyed a similar drop in dementia risk, and those who both listened to and played music had the lowest risk of all. Music seemed to do more than protect against illness. Those who listened regularly performed better on memory and overall thinking tests as the years went by. However, not every type of thinking was affected equally—skills like reasoning or attention showed less change. Interestingly, the benefits were strongest in people with more years of formal education. That might mean that education helps the brain make better use of musical stimulation, or it could simply reflect a lifetime of habits that support mental sharpness. Either way, the link between music and brain health was clear. The study cannot prove that music itself prevents dementia. People who are already healthier or more socially active may also be the ones who enjoy music most often. Yet even allowing for that, the pattern suggests that music could be an important piece of the puzzle. There are many reasons why music might help the brain. Listening or playing involves several areas at once—hearing, movement, memory, and emotion. It can lift mood, reduce stress, and bring people together socially. These effects may all combine to build resilience in the ageing brain. For most of us, this is encouraging news. You do not need to be a lifelong musician or a concert-goer to benefit. Simply making music part of daily life—listening to favourite songs, singing along, tapping out rhythms, or taking up a simple instrument—might help keep the mind active and connected. The message is both hopeful and practical: keep the music on. It may not be a cure, but it is an easy, enjoyable way to give your brain a workout and perhaps lower your risk of dementia as you grow older.
