40% of dementia cases could be prevented with simple lifestyle shifts
Up to 40% of dementia cases could be prevented or delayed through lifestyle changes, according to health experts. The World Health Organization (WHO) has issued guidelines to help healthcare providers support patients in reducing their risk. Simple adjustments, from diet to exercise, may make a significant difference in long-term brain health.
Regular physical activity plays a key role in lowering dementia risk. Studies show that brisk walking for 150 minutes each week can cut the likelihood of developing the condition by up to 28%. Exercise improves blood flow to the brain and supports cognitive function.
Controlling blood pressure also protects against vascular dementia. High blood pressure damages delicate blood vessels in the brain over time. Managing it through medication or lifestyle changes helps maintain brain health.
A balanced diet further reduces risk. Eating plenty of fruits, vegetables, whole grains, and lean proteins provides essential nutrients that support memory and thinking. Meanwhile, limiting alcohol prevents neurotoxic damage, while quitting smoking lowers oxidative stress on brain cells.
The WHO has expanded its support beyond prevention. Its iSupport programme offers practical advice for caregivers, helping them manage daily challenges. With global dementia care costs projected to hit $2 trillion annually by 2030, these measures aim to ease the burden on families and healthcare systems.
Adopting healthier habits could delay or prevent a large number of dementia cases. The WHO's guidelines give clear steps for individuals and caregivers to follow. Small, consistent changes in diet, exercise, and lifestyle may lead to long-term benefits for brain health.
