Seniors whose cholesterol levels spike and plummet year-to-year could be at increased risk of dementia and failing brain health, a new study suggests.

Could changes in cholesterol be a warning sign of dementia? A new study suggests that older adults whose cholesterol fluctuates significantly over time are more likely to develop dementia than those with stable levels.

A new study reveals that seniors with fluctuating cholesterol levels face a 60 per cent higher risk of dementia and a 23 per cent increased risk of mild cognitive impairment. Researchers suggest that monitoring cholesterol variability could help identify people at risk.

Changes to a person's cholesterol over time might have a surprising impact on their risk of dementia, a new study found.
