People with higher levels of cholesterol could be at an elevated risk of developing Alzheimer's disease, according to scientists.
Those with more lipids like cholesterol in their system were more likely to have amyloid plaques in their brain, according to research published in journal Neurology.
Amyloid plaques are one of the hallmarks of the neurodegenerative condition.
However, the presence of another characteristic of Alzheimer's known as tau protein was not found to be linked to cholesterol levels.
Dr Anne Corbett, research manager at the Alzheimer's Society, said: "We're often given stark warnings about the dangers of high cholesterol. This research adds further weight to the argument that it's not only bad for the heart but it's also bad for the head."
This follows news that a Cambridge-University developed Alzheimer's test could diagnose the condition in ten minutes.
The Cantab Pal can be taken on an iPad and touch screen computer, with researchers saying it could easily be taken in the doctor's office.
