'Good' cholesterol and Alzheimer's disease

Researchers from Columbia University in New York have been looking into the links between 'good' cholesterol - high-density lipoprotein (HDL) - and Alzheimer's disease. They studied 1,130 adults in northern Manhattan none of whom had dementia or cognitive impairment at the start of the study. As the participants were followed over time there were 101 new cases of Alzheimer's disease. Having higher levels of HDL cholesterol was associated with a decreased risk of developing Alzheimer's even after adjusting for vascular (blood vessel) risk factors and cholesterol-lowering treatments. Being Hispanic and having diabetes at the start of the study both increased the risk of developing Alzheimer's.
