New World Health Organization (WHO) guidelines suggest up to 45% of dementia risk could be prevented or delayed by addressing modifiable factors like smoking, excessive alcohol consumption, lack of exercise, diabetes, and high blood pressure. The guidelines emphasize lifestyle changes such as a healthy diet, physical activity, mental engagement, and reducing exposure to air pollution. They explicitly advise against using vitamin and mineral supplements, including B and E vitamins, omega-3s, and multivitamins, to prevent dementia. Additionally, the guidelines conditionally recommend against menopausal hormone therapy (MHT) for women over 65 to reduce dementia risk, though there is limited evidence regarding its use for younger women with certain conditions.
