Cholesterol is a necessary fatty substance that is both manufactured by the liver and obtained through dietary intake.Elevated cholesterol levels have the potential to lead to various health issues, such as coronary heart disease.A recent study indicates that older adults may face a higher risk of dementia due to changing cholesterol levels.The researchers propose that monitoring cholesterol levels annually could help evaluate the likelihood of dementia and cognitive decline in elderly individuals.Cholesterol, a waxy substance akin to fat, is synthesized by the liver and plays a crucial role in forming cell membranes, certain hormones, and bile salts necessary for the digestion of fats.It is also found in a variety of foods such as meat, seafood, poultry, eggs, and dairy products. The Centers for Disease Control and Prevention (CDC) recommend limiting the consumption of foods high in cholesterol to prevent potential health issues like heart attacks and strokes.Elevated cholesterol levels can be influenced by dietary choices and lifestyle habits or may also be attributed to genetic predisposition, specific health conditions, and certain medications. According to the CDC Trusted Source, approximately 25 million adults in the United States have elevated cholesterol levels, measuring 240 milligrams per deciliter (mg/dL) or higher.Two distinct types of cholesterol, each with varying effects on health, are present.Recent research indicates that not just high cholesterol, but also varying levels of cholesterol, could impact one’s health.During the American Heart Association’s Scientific Sessions 2024, a study was presented indicating that changes in cholesterol levels each year could potentially raise the likelihood of dementia and cognitive decline in older adults. Please note that the study has not yet been peer-reviewed.Emer MacSweeney, MD, a consultant neuroradiologist at Re:Cognition Health, offered insights on why such changes might have an impact, despite not being part of the research team.She mentioned to Medical News Today that:Changes in cholesterol levels, especially LDL cholesterol, could potentially elevate the risk of developing dementia by affecting the stability of atherosclerotic plaques. The destabilization of plaque may result in a heightened risk of plaque rupture and reduced blood flow, impacting brain function.
