Cholesterol levels healthy for the brain too

  • 0

Low levels of “bad” cholesterol and high levels of “good” cholesterol are associated with lower levels of the amyloid plaque deposition in the brain, which is a hallmark of Alzheimer’s disease, in a pattern that is similar to the relationship between bad and good cholesterol in cardiovascular disease, according to researchers at UC Davis.

“Unhealthy patterns of cholesterol could be directly causing the higher levels of amyloid known to contribute to Alzheimer's, in the same way that such patterns promote heart disease,” Bruce Reed, lead study author and associate director of the UC Davis Alzheimer's Disease Center, was quoted as saying.

Charles Decarli, director of the Alzheimer's Disease Center and an author of the study, believes that it is a wake-up call that, just as people can influence their late-life brain health by limiting vascular brain injury through controlling their blood pressure, the same can be said for gaining control of their serum cholesterol levels.
