The Surprising Link Between High 'Good' Cholesterol and Dementia

High levels of HDL cholesterol, often referred to as "good" cholesterol, may increase the risk of dementia, according to a study by Boston University. The research, which followed 185,000 participants over nearly a decade, found that those with the highest levels of HDL cholesterol had a 15% higher risk of dementia compared to those with average levels. The study did not find a similar link between low-density lipoprotein (LDL) cholesterol, known as "bad" cholesterol, and dementia risk. The findings challenge the traditional belief that higher HDL cholesterol levels are always beneficial and highlight the complex relationship between cholesterol and dementia.
