People with low LDL cholesterol levels are much less likely to be diagnosed with dementia and Alzheimer’s disease, according to new research.
Keeping your LDL or bad cholesterol level in check may help reduce your risk of dementia and Alzheimer’s disease.
A new study finds people with low levels of low-density lipoprotein cholesterol or LDL-C are much less likely to be diagnosed with both brain conditions.
Researchers analyzed data from 570,000 neurologically healthy adults who were followed for at least 180 days after cholesterol testing.
About one-third of the participants had low LDL blood levels — less than 70 milligrams per deciliter. The remainder had high levels — more than 130 milligrams per deciliter.
Those below the 70- milligram mark had a 26% reduced risk of all-cause dementia and a 28% reduced risk of Alzheimer’s disease, according to the results. People with low LDL cholesterol who used statins saw an even bigger benefit.
The authors say, “These findings underscore the crucial role of managing LDL-C in lowering dementia risk.”
Prior investigations have shown low LDL-C also protects against heart attack and other cardiovascular events.
