World Brain Day is a global initiative led by the World Federation of Neurology to raise awareness about neurological health and encourage actions that protect the brain throughout life. It is observed annually on July 22nd. The 2026 theme, “Brain Health: Access for All,” reminds us that everyone deserves the opportunity to prevent neurological disease, access timely care, and live with the best possible brain health regardless of where they live or their circumstances.
This year’s theme also aligns with findings from the report of the 2024 Lancet Standing Commission on Dementia Prevention, Intervention and Care. After reviewing the latest scientific evidence, the Commission concluded that up to 45% of dementia cases worldwide could potentially be delayed or prevented by addressing fourteen modifiable risk factors across the life course. As we mark World Brain Day, this article explores the Lancet Commission’s findings and highlights practical steps each of us can take to support lifelong brain health.
The 14 Modifiable Risk Factors: Key Messages for Protecting Your Brain The Lancet Commission groups the risk factors according to the stages of life when they have the greatest impact. Together, they remind us that protecting brain health is a lifelong journey that begins in childhood and continues well into older age. Early Life: Build a Strong Brain Foundation 1.
Education Education during childhood lays the foundation for lifelong brain health. Learning strengthens the brain by building what scientists call cognitive reserve – the brain’s ability to cope with ageing and disease. Investing in education is therefore not only an investment in knowledge and future careers, but also in reducing the risk of dementia later in life.
Midlife: Protect the Brain by Protecting the Body The Commission highlights that many of the conditions affecting the heart and blood vessels also affect the brain. Looking after your physical health during midlife is one of the most effective ways to reduce dementia risk. Hearing Loss Untreated hearing loss reduces the amount of sound stimulation reaching the brain and may also lead people to withdraw from conversations and social activities.
Early hearing assessment and the appropriate use of hearing aids can help maintain communication, social engagement and cognitive function. High LDL (“Bad”) Cholesterol High levels of LDL c…
