Keep Cholesterol In Check To Ward Off Dementia

The national study shows that not only high cholesterol, but also borderline high cholesterol, is associated with dementia.  

Researchers noted that studies have shown that treatment with a cholesterol-lowering statin drug may lower the risk of dementia.   “What’s good for the heart may be good for the mind,” says Jesse Slome, executive director of the American Association for Long-Term Care Insurance.  Alzheimer’s disease is one of the nation’s leading causes of need for costly long-term care. 

The study, published in the journal Dementia and Geriatric Cognitive Disorders, involved 9,844 men and women whose cholesterol levels were determined between 1964 and 1973 when they were 40 to 45 years old. 

Between 1994 and 2007, a review of their medical records showed that 469 had Alzheimer’s disease and 127 had vascular dementia, the second most common form of dementia after Alzheimer’s disease, which is caused by clogged blood vessels and other conditions affecting the blood supply to the brain. 

Compared to people with desirable cholesterol levels below 200 milligrams per deciliter of blood (mg/dL) in midlife, the risk of Alzheimer’s disease three decades later was 57 percent higher in people with high midlife cholesterol levels of 240 mg/dL and above. 

Borderline high cholesterol (200 to 239 mg/dL) tended to increase the risk of Alzheimer’s disease as well, but the results were not statistically significant.  However, midlife borderline high cholesterol increased the risk of vascular dementia by 50 percent. High midlife cholesterol also tended to increase the risk of this type of dementia.
