Dementia Risk Can Be Reduced: WHO Issues Recommendations

The World Health Organization (WHO) is now explicitly recommending social engagement and mentally stimulating activities as key strategies to lower the risk of dementia. This updated guidance acknowledges growing evidence that an active social life, alongside physical exercise and a healthy diet, plays a crucial role in cognitive health. The organization now explicitly advises people to maintain social connections and participate in activities like reading, storytelling, and playing games.

Previously, in 2019, the WHO stated there was insufficient scientific evidence to confirm that social interaction reduced dementia risk. However, the organization now recognizes that up to 45% of dementia risk is attributable to modifiable factors. Measures that improve overall health, such as managing high blood pressure, diabetes, obesity, sleep disorders, and depression, also contribute to protecting against dementia, the WHO emphasized.

Furthermore, the WHO has updated its stance on hearing loss, now finding clear evidence that hearing aids can help prevent cognitive decline in individuals with hearing impairments. The benefits of cleaner air, both indoors and outdoors, and reduced exposure to fine particle pollution are also highlighted. Conversely, the WHO remains cautious about the effectiveness of supplements like Vitamin B, Vitamin E, omega-3, or multivitamins in preventing dementia, unless a specific deficiency is present, citing insufficient supporting evidence.

Globally, approximately 57 million people currently live with dementia, a figure projected to rise significantly. There is no known cure for the disease, making prevention and risk reduction strategies increasingly vital.
