"A study of older adults found that those who always listened to music had a 39% lower risk of dementia than people who listened less often."
Verdict

Confidence
HighSummary
The Instagram post refers to a real study by Emma Jaffa and colleagues at Monash University, published in the International Journal of Geriatric Psychiatry in 2025. It analyzed roughly 10,893 Australians aged 70 and older from the ASPREE cohort and found that participants who reported "always" listening to music had about a 39% lower risk of a dementia diagnosis compared with those who listened never, rarely, or sometimes. The 39% figure is accurate, and the post correctly notes that this is an association rather than proof that music prevents dementia. The main caveats are that this was an observational study with no randomization, meaning causation cannot be established, and reverse causation (early cognitive decline reducing music engagement) is plausible. Some of the mechanisms the post lists, such as effects on memory and reward networks, are general background and were not directly measured in this study.

Why this verdict
Evidence
The referenced study exists and is correctly attributed. "What Is the Association Between Music-Related Leisure Activities and Dementia Risk? A Cohort Study" by Emma Jaffa et al. was published in the International Journal of Geriatric Psychiatry.
The study, led by Monash honors student Emma Jaffa and Professor Joanne Ryan, looked at people aged over 70 and found that always listening to music, compared with never/rarely/sometimes listening to music, was associated with a 39% decreased risk of dementia. Playing an instrument was associated with a 35% reduction in dementia risk.
Always listening to music was linked to a 39% reduced dementia risk (95% CI = 0.45, 0.82, p = 0.001) and a 17% lower risk of cognitive impairment no dementia (CIND).
Findings
✓ What's accurate 5
- The study exists, was led by Emma Jaffa at Monash University, and was published in the International Journal of Geriatric Psychiatry.
- The 39% figure is accurate as a relative risk reduction in the "always" listeners group.
- The claim correctly frames the finding as an association, not proof of causation.
- The reference group is people who listened less often, which matches the source's "never/rarely/sometimes" combined comparator.
- The National Institute on Aging is a legitimate secondary source on dementia and cognitive aging.
≈ What's misleading 2
- Minor simplification: the reference group in the study is "never/rarely/sometimes" combined, not simply "people who listened less often." Adults who reported listening "often" were treated separately and did not show the same magnitude of effect. The post's phrasing slightly blurs this distinction, but it does not materially change the meaning.
- The post's bulleted mechanisms (memory, attention, emotion and reward networks; cognitive reserve) are general background claims and are not specific findings of this study. They are presented adjacent to the study result in a way that could imply the study demonstrated them, when in fact the study measured self-reported music engagement and dementia diagnosis rates, not brain network activity.
? What's uncertain 4
- Causality cannot be established from this observational design. Reverse causation is plausible: people in early, undiagnosed cognitive decline may reduce leisure activities including music listening, which can inflate the apparent protective association.
- Residual confounding by education, socioeconomic status, hearing ability, social engagement, and general activity levels is possible even after statistical adjustment.
- Generalizability beyond community-dwelling, relatively healthy Australians aged 70 and older is not established.
- The exact wording of the survey question categorizing music listening frequency was not retrieved in this investigation.
