Common Cholesterol-Lowering Drugs May Reduce Dementia Risk
A major international study led by the University of Bristol, published in Alzheimer’s & Dementia, found that lower cholesterol levels may play a key role in protecting against dementia.
Researchers drew on data from over one million people and found that individuals with genetic traits that naturally reduce cholesterol were less likely to develop dementia.
Cholesterol control could also benefit brain health and potentially prevent cognitive decline.
Excessive cholesterol levels can cause blockages that limit blood flow and increase dementia risk, but cholesterol also contributes to brain and vascular health.
