So-called "good" cholesterol, known by its initials as HDL-C, plays an important role in maintaining memory in later life, according to a study published Monday.
A French-led team looked at cholesterol levels and memory deficit among 3 673 male and female civil servants, who were assessed when they reached the age of 55 and again when they reached 61.
Low levels of HDL-C (40 milligram's per decilitre or less) were associated with a greater risks of a memory gap in both assessments, when compared with high levels (60 mg/dL or more) of this lipo-protein.
How the test was doneThe paper appears in the US journal Ateriosclerosis, Thrombosis and Vascular Biology, published by the American Heart Association.
The test comprised the ability to recall the maximum number of words in a 20-word list. "HDL-C levels are potentially modifiable, and our results show that low HDL-C is associated with poor memory and decline in memory in
middle-aged adults," the study said.
Lead author is Archana Singh-Manoux of the National Institute for Health and Medical Research (INSERM).
Cholesterol is notoriously implicated in cardiovascular disease, notably when there are high levels of "bad" cholesterol, or LDL-C, compared with levels of HDL-C. – (Sapa)
