High levels of ‘good’ cholesterol could lower risk of Alzheimer’s disease, study claims
Published 14 December 2010
High levels of high-density lipoprotein (HDL), or ‘good’ cholesterol, could lessen the chances of developing Alzheimer’s disease in older adults, claims a study.
US researchers studied 1,130 older adults to explore the links between fat levels in the blood and Alzheimer's disease. Higher levels of HDL cholesterol were linked with a decreased risk of developing Alzheimer's disease, even when allowing for vascular dementia risk factors and treatments to lower blood fat levels.
Alzheimer's Society comment:
'This large study links 'good' cholesterol (HDL) with a lower risk of developing Alzheimer's disease. This is interesting because until now, researchers have focused on the associations between 'good' cholesterol and vascular dementia. The best way to reduce your risk of dementia is to get your blood pressure and cholesterol checked, eat a healthy Mediterranean-style diet and watch your weight.
'More research is now needed to fully understand the link between HDL cholesterol and the processes that lead to Alzheimer's disease. Yet the government invests eight times less in dementia research than cancer research. If we want to see the same advancements in dementia care as we have for cancer we must invest more.'
