When it comes to cholesterol, it’s typically categorized into “good” and “bad” types based on its impact on heart health, but new research suggests that “good” cholesterol may come with other health risks. It has been shown that there is a sex. .
this is high density lipoprotein New research has linked too much cholesterol (HDL-C) to an increased risk of dementia in older adults. For those over 75, the risk increased by 42 percent, the analysis showed.
The study, led by a team at Monash University, looked at data from 18,668 adults aged 65 and over in Australia and the US. Overall, those diagnosed with high HDL-C levels had an average increased risk of dementia of 27% and were followed for an average of 6.3 years.
“This is the most comprehensive study reporting high HDL-C and risk of dementia in older adults,” the researchers wrote in their paper. published papers. “Study results showed that high HDL-C is associated with dementia risk, and that risk increases with age.”
Most of the cholesterol in our bodies is of the low-density lipoprotein (LDL) or “bad” type, and high amounts of cholesterol in the blood can clog arteries and increase the risk of heart disease and stroke. The main benefits of HDL-C are: Maintain LDL-C levels Checking in progress.
Normal levels of HDL-C in the blood are considered to be 40 to 50 milligrams per deciliter (or mg/dL) for men and 50 to 60 mg/dL, or approximately 40 to 60 ppt, for women. It is being Almost 15 percent of participants (2,709 people) had what was considered high HDL-C levels (80 mg/dL or higher) at the start of the study.
The increase in risk was a significant jump, and the association remained significant even after adjusting for factors such as age, gender, education, alcohol consumption, and daily exercise. However, this does not prove that cholesterol is responsible for the increase in dementia, there is only evidence of an association.
“We know that HDL cholesterol is important for cardiovascular health, but this study suggests that further research is needed to understand the role of very high HDL cholesterol in brain health. Masu.” To tell Monira Hussain, an epidemiologist at Monash University.
The researchers did not delve into possible biological mechanisms linking high HDL-C and dementia, which could be considered in future studies. What we do know is that everything in our bodies is closely linked, including the heart and brain.
Experts still don’t know exactly how dementia begins, so finding a link like this can help steer research in the right direction. Furthermore, in the future, it may help develop preventive treatments and treatments, and recognize who is likely to develop dementia and who is not.
“It may be useful to consider very high HDL cholesterol levels in dementia risk prediction algorithms.” To tell Hussein.
