WHO Dementia Risk Guidelines: Up to 45% of Cases Could Be Prevented or Delayed
The WHO Dementia Risk Guidelines say up to 45% of dementia cases could be prevented or delayed. The World Health Organization urges people to reduce tobacco and alcohol use, stay active, and control health conditions. In addition, the guidance highlights the importance of reducing air pollution and avoiding social isolation. Experts believe these steps can protect brain health throughout life.
Dementia affects memory, thinking, and daily activities. More than 57 million people currently live with the condition worldwide. Around 10 million new cases appear every year. Alzheimer’s disease remains the most common type and accounts for most diagnosed cases. Therefore, WHO encourages countries to act early and support healthier lifestyles.
Healthy Habits Protect Brain Health
WHO says healthy daily choices can lower dementia risk. Regular physical activity supports both the body and the brain. Likewise, eating a balanced diet and limiting alcohol intake can improve long-term health. People should also quit smoking because tobacco harms blood vessels and brain function.
Experts also recommend cognitive training and mental activities. Reading, learning new skills, and solving puzzles can keep the brain active. Furthermore, spending time with family and friends helps reduce loneliness and supports cognitive health.
Managing Health Conditions Matters
WHO advises people to manage high blood pressure, diabetes, and high cholesterol with proper medical care. These conditions increase the risk of cognitive decline if left untreated. As a result, regular health checkups become an important part of prevention.
The updated guidance also recommends reducing exposure to air pollution whenever possible. In addition, hearing aids may help people with hearing loss as part of dementia risk reduction. WHO Director-General Dr. Tedros Adhanom Ghebreyesus said countries now have clear, evidence-based recommendations to protect cognitive health. Overall, early awareness, healthier habits, and timely treatment can help people lower dementia risk and enjoy better brain health for many years ahead.
