WHO Reveals How Lifestyle Changes Can Slash Dementia Risk by 40%

Dementia affects 50 million people globally, with nearly 10 million new cases reported each year. To tackle this growing issue, the World Health Organization (WHO) released guidelines on 14 May 2019 aimed at preventing cognitive decline through lifestyle changes. The WHO’s report highlights that up to 40% of dementia cases could be prevented or delayed by addressing modifiable risk factors. Key recommendations include avoiding smoking, limiting alcohol intake, and following a balanced diet rich in fruits, vegetables, whole grains, and lean proteins.

Regular physical activity, such as 150 minutes of brisk walking per week, can reduce dementia risk by up to 28%. The guidelines also stress the importance of managing blood pressure, cholesterol, and blood sugar—factors that protect both heart and brain health. Controlling blood pressure is particularly crucial, as it prevents damage to blood vessels in the brain, a major contributor to vascular dementia. The WHO’s message is clear: what benefits the heart also benefits the brain, reinforcing the link between cardiovascular and cognitive well-being.

Adopting a healthier lifestyle could significantly cut the risk of dementia. The WHO’s guidelines provide actionable steps, from diet and exercise to managing chronic conditions. These measures offer a practical way to protect cognitive health as people age.
