New advice from the World Health Organization (WHO) indicates that lifestyle changes could reduce the risk of dementia by up to 50%. The report, released on July 20, 2026, emphasizes managing hearing loss, high blood pressure, diet, and sleep as key factors.
According to the WHO, addressing hearing loss in midlife could prevent up to 8% of dementia cases. Controlling high blood pressure, especially from age 40, may reduce risk by 10%. A healthy diet, regular exercise, and avoiding smoking and excessive alcohol are also recommended.
The report updates previous guidelines from 2019, adding new evidence on sleep and social engagement. The WHO stresses that these measures are most effective when started early, but benefits can occur at any age.
