WHO Updates Dementia Prevention Guidelines

The World Health Organization released updated guidelines aiming to reduce the global impact of dementia, asserting that 45 percent of cases could be delayed or prevented by addressing modifiable risk factors. Over 57 million people worldwide currently live with dementia, and nearly 10 million new cases emerge annually, with Alzheimer’s disease accounting for 60 to 70 percent of all cases.

The WHO recommends regular physical activity, avoiding tobacco and excessive alcohol, a healthy diet, cognitive training, and social engagement. New to these guidelines is a recommendation to reduce exposure to air pollution and the potential benefit of hearing aids.

The agency cautioned against using vitamin B, E, omega-3 fatty acids, or multivitamins specifically to prevent dementia without a diagnosed deficiency. Dementia currently costs the global economy approximately $1.3 trillion each year, with unpaid family care constituting half of that expense. The WHO hopes integrating dementia prevention into existing health services will improve outcomes and quality of life for those at risk.
