Midlife cholesterol levels linked to dementia

eggs and bacon clip artSan Francisco Chronicle (August 4, 2009) -- You might want to think twice about that plate of steak and eggs.

A new study that looked at Kaiser Permanente Northern California members over a four-decade period found that even borderline to moderately high cholesterol levels in your 40s can significantly raise the chances of developing dementia later in life.

The study, published today in the journal Dementia & Geriatrics Cognitive Disorders, found the risk for developing Alzheimer's disease increased by as much as 66 percent among people with high cholesterol in midlife, a level defined as 240 or higher milligrams per deciliter (1.75 pints) of blood.

For those with just moderately high cholesterol - between 200 and 239 milligrams per deciliter - the risk of developing vascular dementia, the second-most common form of dementia after Alzheimer's, increased by 52 percent.
