Higher levels of 24-OHC suggest increased cholesterol metabolism occurring in the brains of participants with cerebrovascular disease prior to the onset of cognitive impairment. Measurement of oxysterols may provide information about cholesterol metabolism and brain disease over the cognitive impairment ...
"We're only at the beginning of this research on how diabetes and Alzheimer's disease could be related, but cholesterol could be a mediator," says Ferris. While investigators in other labs have suggested that raised rather than lower levels of cholesterol may be linked to brain disorders, "w...
"Cholesterol in blood and cholesterol in brain are separate 'pools,' walled off from one another by the blood brain barrier. We measured cholesterol in blood. So that is one question that needs to be answered - how do cholesterol levels in blood and in brain influence each other," Reed sa...
The strange idea that cholesterol causes atherosclerosis was revived in the 1950s when the vegetable oil industry learned that their polyunsaturated oils lowered serum cholesterol. (Many other toxins lower cholesterol, but that is never mentioned.) The industry began advertising their oils as "heart p...
Our data show that chronic simvastatin treatment decreased cholesterol levels in the brain and affected cholesterol distribution within SPM. Simvastatin significantly increased the levels of insoluble A beta(1-40) and A beta(1-42) but reduced levels of soluble A beta(1-40) in the brain. The ...

Cholesterol homeostasis is highly regulated in the nervous system; dysregulation in cholesterol trafficking and content have been involved in the pathogenesis of neurodegenerative diseases (such as Parkinson's and Alzheimer's diseases). Furthermore, low cholesterol levels during brain development are associa...
By measuring the levels of 24S-hydroxycholesterol in serum samples from the internal jugular vein and the brachial artery, a net flux could be demonstrated from the brain into the circulation. Based on measurements in eight subjects, the net flux of 24-hydroxycholesterol into the circulation was ...
a sterol, C27H46O, abundant in animal fats, brain and nerve tissue, meat, and eggs, that functions in the body as a membrane constituent and as a precursor of steroid hormones and bile acids: high blood levels are associated with arteriosclerosis and gallstones. ...
