WHO Reveals How Lifestyle Changes Could Prevent 40% of Dementia Cases

Dementia affects nearly 50 million people across the globe, with almost 10 million new cases reported each year. Experts now say that up to 40% of these cases could be prevented or delayed through simple lifestyle changes. On May 14, 2019, the World Health Organization (WHO) released guidelines to help reduce cognitive decline. The recommendations include regular physical activity, such as brisk walking for 150 minutes a week, which can lower dementia risk by up to 28%. Quitting smoking, cutting back on alcohol, and eating a balanced diet rich in fruits, vegetables, whole grains, and lean proteins also play a key role.

A healthy lifestyle helps protect brain health by managing blood pressure, cholesterol, and blood sugar levels. These factors, if left uncontrolled, can damage blood vessels in the brain over time. The WHO also introduced *iSupport*, an online training programme designed to assist caregivers of people living with dementia. Without intervention, the financial burden of dementia care is expected to rise sharply. By 2030, global costs could reach $2 trillion annually.

Adopting healthier habits could significantly cut the number of dementia cases worldwide. The WHO’s guidelines highlight practical steps, from diet and exercise to better health management, that may help delay or prevent cognitive decline. These measures could ease the growing economic and social impact of the condition.
