Alzheimer's Society comment on the link between high density lipoprotein and dementia
Published 1 July 2008
One of the functions of High Density Lipoprotein (HDL) is to transport cholesterol from the arteries back to the liver to be degraded.
It is clearly important to have enough of this transporter available. This study shows that if there is not enough High Density Lipoprotein to transport cholesterol and other lipids around the body, it can not only increase your risk of heart disease but also affect your memory and may increase your risk of getting Alzheimer's disease.
We know that controlling cholesterol in midlife is important if you are to reduce your risk of developing vascular dementia later and this may also be important for the development of Alzheimer's disease. People should eat a healthy diet, low in salt and saturated fat and take regular exercise.
If you have high cholesterol you should also actively seek treatment from your GP to ensure you are doing everything possible to reduce your risk of dementia in later life.

Comment on "Low HDL Cholesterol Is a Risk Factor for Deficit and Decline in Memory in Midlife" The Whitehall II Study. Authors Archana Singh-Manoux, David Gimeno, Mika Kivimaki, Eric Brunner, Michael G. Marmot. The link between high density lipoprotein (HDL) - or "good" cholesterol - and dementia emerged from a study of 3,673 civil servants. Scientists found that participants with low levels of HDL were more likely to suffer memory decline by the age of 60.
