According to the report, researchers conducted two separate studies in 2026 focused on dementia prevention. The first study, published in The Lancet Healthy Longevity, found that public awareness campaigns by themselves rarely produce long-term changes in behavior. The second study, published in Clinical Nutrition, revealed that individuals with low muscle strength combined with excess body fat had a substantially higher risk of developing dementia.

Mario Siervo, Professor at the School of Population Health at Curtin University, explained that up to 45% of dementia cases are associated with modifiable risk factors, including lifestyle choices, health conditions, and environmental influences. However, he emphasized that simply informing people about these risks is often insufficient to drive meaningful behavioral change.

Researchers reviewed dementia prevention initiatives across eight countries and found that personalized, community-based interventions were considerably more successful in encouraging healthier lifestyle choices than awareness campaigns alone.

Why Muscle Health Matters for Brain Health

The second study tracked nearly 500,000 adults over more than ten years and found that individuals with both low muscle strength and excess body fat—a condition known as sarcopenic obesity—faced a significantly greater risk of developing dementia.

Interestingly, obesity by itself was not associated with an increased dementia risk when muscle strength was maintained, highlighting the protective role of preserving muscle function as people age.

Co-author Blossom Stephan noted that many people still view dementia as an unavoidable consequence of aging, despite growing evidence showing that a considerable number of cases may be delayed or prevented through healthier lifestyle choices.

A Brain-Healthy Habit Many Men Already Practice

Many men engage in exercise primarily to build muscle or maintain a healthy body composition. This research provides another compelling reason to prioritize physical fitness.

Strength training, regular physical activity, a nutritious diet, and maintaining healthy blood pressure levels may not completely eliminate the risk of dementia, but they are among the lifestyle factors with the strongest evidence for supporting long-term brain and physical health. As people age, investing in these habits can provide significant benefits for both body and mind.
