High cholesterol linked to dementia development, study reveals

A study by The Lancet Commission identifies high cholesterol and vision loss as key factors in dementia development, alongside 14 modifiable risks that could prevent or delay nearly 50% of cases. The research highlights that addressing these risks, including smoking cessation and improving education, could reduce dementia likelihood by up to 45%. Global dementia cases are projected to nearly triple by 2050, with costs exceeding $1 trillion annually.
