In addition to total cholesterol, the study tracked triglycerides, a type of fat that comes from butter and oils; low-density lipoprotein cholesterol, also known as LDL or “bad” cholesterol; and high-density lipoprotein cholesterol, known as HDL or ‘good’ cholesterol. In the Neurology study, variations in LDL and HDL cholesterol weren’t associated with higher risk for Alzheimer’s disease or related dementias. Lipids and neurodegenerative diseaseThe authors found a link, but not a causal relationship, between fluctuating levels of cholesterol and triglycerides and risk of Alzheimer’s disease and related dementias. Exactly how varying lipid levels and risk for Alzheimer’s or related dementias are related remains unclear, Bielinski said. “Always consult your doctor or healthcare provider if you are concerned about your cardiovascular health, cholesterol levels, or cognitive decline,” Weber said via email.
