High good and low bad cholesterol are not just good for the heart but also the brain, suggests new research published in JAMA Neurology.
Study leader Bruce Reed, a professor of neurology at the University of California (UC) Davis, and associate director of its Alzheimer's Disease Center, says:
"Our study shows that both higher levels of HDL - good - and lower levels of LDL - bad - cholesterol in the bloodstream are associated with lower levels of amyloid plaque deposits in the brain."
He explains that while we already have long-standing evidence of raised cholesterol linked to a higher risk of developing Alzheimer's, their study is the first to link it to amyloid plaques in the brains of living people.
Prof. Reed says:
"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."
