The Claim
In older adults aged 65 and older without dementia, baseline low-density lipoprotein cholesterol (LDL-C) levels show no association with the risk of developing dementia, mild cognitive impairment, or cognitive decline, irrespective of statin use.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In people aged 65 and older without dementia, the level of LDL cholesterol in the blood at the start of the study does not relate to whether they later develop dementia, mild cognitive impairment, or cognitive decline, whether or not they take statins.
See the scientific wording
In older adults aged 65 and older without dementia, baseline low-density lipoprotein cholesterol (LDL-C) levels are not associated with the risk of dementia, mild cognitive impairment, or cognitive decline, regardless of statin use.
In older adults, the amount of LDL cholesterol in the blood does not trigger changes in the brain that lead to memory loss or dementia, even when cholesterol-lowering drugs are used, because brain cells do not rely on blood cholesterol to function or survive.
What the research says
1 studyStudy: Effect of Statin Therapy on Cognitive Decline and Incident Dementia in Older Adults
This study found that taking statins — pills that lower cholesterol — didn’t make older adults more or less likely to develop memory problems or dementia. That suggests that how high or low your cholesterol is at the start probably doesn’t affect your risk of memory issues later.
