Maintaining optimal cholesterol levels is not only important for cardiovascular health – it can also significantly reduce the risk of dementia. A large-scale study published in Journal of Neurology, Neurosurgery & Psychiatry analysed data from over 570,000 adults in South Korea. The results were striking: individuals with LDL-cholesterol levels under 70 mg/dl had a
• 26 % lower risk of developing dementia from any cause
• 28 % lower risk of developing Alzheimer’s disease
In addition, the study found that among individuals with low LDL-cholesterol levels, the use of statins was associated with an additional 13 % reduction in dementia risk.
The experts suggest that elevated LDL-C may contribute to inflammation and oxidative stress, both of which are involved in cognitive decline and neurodegeneration.
Practical conclusion:
Incorporating heart-healthy habits — such as a balanced diet rich in fruits, vegetables, whole grains and healthy fats — together with regular physical activity supports both cardiovascular and cognitive longevity. If you aim to reduce your risk of dementia, it’s time to review your lipid profile.
