The Impact of Good Cholesterol Levels on Dementia Risk

High levels of HDL-C, or "good cholesterol," may be associated with an increased risk of dementia in older adults, according to a new study. The study found that very high levels of HDL-C, which were uncommon and not related to diet, were more likely to indicate a metabolic disorder. Researchers suggest that HDL cholesterol behaves differently in the brain compared to the rest of the body, potentially increasing the risk of stroke and causing pro-inflammatory changes that may be related to certain forms of dementia. However, more research is needed to fully understand the association between HDL-C and dementia risk.
