The Two New Factors Raise the Total to 14
Cholesterol May Affect the Brain Through Blood Vessels
Eye Care May Help Preserve Daily Engagement
The Risk Is Modifiable, Not Inevitable

Dementia risk is often discussed through familiar warnings: age, family history, smoking, blood pressure, diabetes, and inactivity. But researchers are now drawing attention to two additional factors that many people may not immediately connect to brain health: untreated vision loss and high LDL cholesterol.
The point is not to make people panic or treat dementia as fully preventable in every case. The stronger message is more practical: some risks can be noticed earlier, discussed with a doctor, and managed before they quietly affect long-term health. The 2024 Lancet Commission added these two factors to its dementia prevention model, estimating that around 45% of dementia cases could potentially be delayed or reduced by addressing 14 modifiable risk factors across life.
