The findings are consistent with the broader understanding that some dementia risk factors are modifiable. Updated global guidance from the World Health Organization has highlighted the potential to prevent or delay a substantial proportion of dementia cases by addressing factors such as high blood pressure, diabetes, smoking, physical inactivity and air pollution. Doctors emphasise the importance of starting prevention early, including controlling blood pressure and blood sugar, avoiding smoking and excessive alcohol, maintaining a healthy weight, staying physically active and managing cholesterol.
