Across the world, 57 million people are living with dementia — a number expected to reach 139 million by 2050 — and researchers at Curtin University are asking whether we have been looking for answers in the wrong place. Published in The Lancet Public Health, their work examining 61 modifiable risk factors suggests that brain health is less a personal achievement than a public outcome, shaped by the neighbourhoods we inhabit, the education we can access, and the air we breathe. The question of prevention, it turns out, may belong less to the individual and more to the systems that govern how a

Households may face increased healthcare costs and demand for aged care services as dementia prevalence grows. Lower-income consumers with limited access to education, quality housing, and healthcare face higher dementia risk, potentially widening health inequalities and increasing out-of-pocket expenses for vulnerable populations.
Governments may need to increase public investment in preventive healthcare infrastructure, affordable housing, education access, and environmental quality. This could drive policy shifts toward integrated social-health programs, increased healthcare budgets, and urban planning reforms prioritizing neighborhood safety and accessibility.
