The World Health Organization (WHO) has published updated global guidance on dementia prevention, emphasizing that millions of future cases could be avoided or postponed by reducing known risk factors. The organization highlights dementia as one of the fastest-growing public health challenges worldwide, affecting millions of people and placing increasing pressure on families and healthcare systems.
According to WHO, important preventive measures include controlling high blood pressure and diabetes, avoiding tobacco use, limiting harmful alcohol consumption, staying physically active, maintaining a healthy diet, protecting hearing, reducing air pollution exposure where possible, and remaining socially and mentally engaged throughout life. The organization stresses that prevention should begin as early as possible and continue across all stages of life.
Health experts say the new recommendations reinforce growing scientific evidence that brain health is closely linked to overall cardiovascular and lifestyle health. Governments are encouraged to strengthen public awareness campaigns, improve access to routine health screening, and integrate dementia prevention into primary healthcare services.
Public health specialists describe the guidelines as a major step toward reducing the future global burden of dementia. With populations ageing rapidly across many countries, early prevention strategies could improve quality of life for millions of people while reducing healthcare costs and easing pressure on long-term care systems.
