Cholesterol in the blood could cause dementia

Except that this dire warning doesn't include the information this earlier reference did. That cholesterol does not cross the blood-brain barrier and other information that 25% of the cholesterol in your body is in your brain. What does your doctor have to say about these competing ideas?

Cholesterol could cause dementia, research warns.

Scientists found a link between the fatty substance in the blood and ­amyloid-beta protein — a key player in the onset of Alzheimer’s disease.

They discovered that cholesterol in the brain is a trigger for the formation of clusters of amyloid-beta. They eventually lead to the formation of amyloid plaques in a toxic chain reaction that results in the death of brain cells.

An international team led by Cambridge University researchers said the identification of a new “pathway” in the brain where amyloid-beta sticks together, or aggregates, could represent a fresh target for potential treatments.

“We’re not saying that cholesterol is the only trigger for the aggregation process, but it’s certainly one of them.”
