Cholesterol levels linked to Alzheimer’s

Unhealthy cholesterol levels are linked to one of the key brain signatures of Alzheimer’s disease, scientists have learned.

Relative amounts of “good” and “bad” cholesterol in the blood influence the build-up of harmful protein deposits in the brain called beta amyloid plaques, a study found.

The discovery may explain the well-known correlation between raised cholesterol and an increased risk of Alzheimer’s.
