Scientists have discovered your cholesterol levels could be significantly linked to your risk of developing dementia. And it’s not just high cholesterol that matters: fluctuating levels over several years could increase your chances of the disease by 60 per cent, suggests a new study of 10,000 people.

The research also suggests that, even if you don’t develop dementia, a large cholesterol variability – swinging from high to low levels – is linked to an increased risk of general cognitive decline by 23 per cent.
