Listening to Music Daily May Lower Dementia Risk by Nearly 40%, Study Finds

Older adults who regularly listen to or play music experience a significantly lower risk of developing dementia compared to those who sometimes, rarely or never engage with music, according to a study conducted by researchers at Monash University in Australia.

Researchers at Monash University recently examined health data from more than 10,800 adults over the age of 70 to understand the long-term cognitive impacts of everyday musical engagement. The study found that people who tuned into music on most days had a 39% decreased chance of developing dementia relative to individuals who engaged with music occasionally, seldom, or never at all. Furthermore, those frequent listeners showed a 17% lower incidence of cognitive impairment, higher overall cognitive scores, and better episodic memory, which governs the recall of everyday personal experiences.

Beyond passive listening, active participation yielded notable advantages. Playing a musical instrument, including singing, was associated with a 35% reduction in dementia risk. Participants who both listened to and played music on a regular basis experienced a 33% reduced risk of dementia and a 22% lower risk of cognitive impairment. With dementia affecting 7 million people—a figure becoming more common as life expectancy increases—these findings offer a low-effort way to ease anxiety.

In Plain English: The Clinical Takeaway

• Full-Brain Activation: Listening to music engages multiple brain areas at once, acting like a full-brain workout that improves processing speed, language, memory, and coordination.
• Active vs. Passive Benefits: Playing an instrument, including singing, was associated with a 35% reduction in dementia risk.
• Episodic Memory Protection: Regular musical habits support better episodic memory, used when we recall specific, everyday events.
• Social Integration: Musical hobbies often involve socializing with others, which helps protect brain health.

Unpacking the Neurological Mechanism of Action

Emma Jaffa, a biomedical science Monash honors student who co-authored the study alongside Joanne Ryan, a professor of biological neuropsychiatry at Monash, noted the broad neurological footprint of musical engagement. “We know that listening to music engages multiple brain areas at once, acting like a full-brain workout,” Jaffa stated.

Previous studies show it improves processing speed, language, memory and coordination. Jaffa said the question she gets most often about the study is, “Are some genres of music more beneficial than others?” While she doesn’t have the answer (participants weren’t asked about what they were listening to), she said it’s definitely something she wants to explore in future research.

Despite these promising correlations, researchers acknowledge several methodological boundaries in the Monash study. Participants were not surveyed regarding specific music genres. In addition, the study concentrated solely on individuals aged 70 and up, meaning further investigation will be necessary to ascertain whether musical engagement has any impact on mitigating cognitive decline risks for people under 70.

Global Public Health Context and Institutional Guidance

Given how devastating dementia symptoms can be, it comes as no surprise that investigators like Ryan and Jaffa are delving into this subject. People with the condition may develop speech difficulties, memory loss, mood changes and trouble completing everyday tasks. A separate recent study, featured in October within the American Journal of Geriatric Psychiatry, concluded that maintaining a sense of purpose may serve as a safeguard against dementia.

Musical Engagement Habit	Observed Dementia Risk Reduction	Cognitive Impairment Reduction
Frequent Listening (Most Days)	39% lower risk	17% lower incidence
Playing an Instrument / Singing	35% lower risk	Not separately isolated
Both Listening and Playing	33% lower risk	22% lower incidence

Contraindications & When to Consult a Doctor

While engaging with music is an activity for older adults, patients and caregivers must distinguish between normal age-related forgetfulness and pathological cognitive decline requiring clinical intervention. Individuals experiencing memory loss, mood changes, or trouble completing everyday tasks should schedule a formal evaluation with a healthcare professional.
