Cholesterol & Brain Health

by Berkeley Wellness  

Desirable blood cholesterol levels may be as important for brain health as for heart health.The latest evidence comes from a recent study published in JAMA Neurology, in which researchers from UC Davis, UC Berkeley, and UCLA did brain scans of people ages 70 or older. They used the scans to measure deposits of amyloid plaque, which are the hallmark of Alzheimer’s disease; they also measured blood cholesterol.

High levels of HDL (“good”) cholesterol and low levels of LDL (“bad”) cholesterol were found to be correlated with lower levels of amyloid in the brain. Previous lab research, observational studies and autopsy reports have linked cholesterol with dementia risk, but this is “the first human experimental evidence of a direct relationship between cholesterol fractions in the blood and amyloid deposition in the brain,” the authors said.
