In Dr. Robert Rowen's e-alert today, he discusses the role of cholesterol and cognitive function. He references "Neurobiology of Aging, Sept. 19, 2007." Does anyone know how to access this study?

One paragraph from the e-alert:

"Researchers recently performed a study on 1,181 subjects over the age of 64. They found that low levels of cholesterol significantly lower general cognitive abilities. They also found that low cholesterol reduces your brain's processing speed. The authors agreed that lower total cholesterol is a strong marker for predicting lower cognitive function in those over 64."
