Keeping your LDL low is good for your heart; it's also good for your brain according to a new study:
A low-density lipoprotein cholesterol (LDL-C) level below 70 mg/dL was associated with a 26% reduced risk of all-cause dementia and a 28% lower risk of Alzheimer’s disease-related dementia (ADRD), with statin use further decreasing that risk, a new study suggests.
While earlier research had suggested lower LDL levels may offer a protective advantage against dementia, these findings provide a specific target number, which investigators said could prove helpful in clinical practice.
“These findings emphasize the importance of targeted LDL-C management as part of dementia prevention strategies, with potential integration into clinical guidelines,” lead investigator Yerim Kim, MD, PhD, Department of Neurology, Kangdong Sacred Heart Hospital, Hallym University College of Medicine, Seoul, South Korea, and colleagues wrote.
Background The link between low-density lipoprotein cholesterol (LDL-C) levels and dementia risk is poorly understood, with conflicting evidence on the role of LDL-C and the impact of statin therapy on cognitive outcomes. Thus, we aimed to examine the association between low-density LDL-C levels and...
