(HDL levels greater than 55 milligrams)

What’s good for your heart may also keep your memory sharp. That’s what a new study on cholesterol from Columbia University suggests. Researchers found that older men and women with very high levels of high-density lipoprotein (HDL) in their blood -- 55 milligrams or more -- had a 60 percent lower risk of developing Alzheimer’s disease than those with lower levels.

Nicknamed “good cholesterol,” HDLs carry artery-clogging cholesterol out of the bloodstream and are linked with a lower risk of heart disease. Low-density lipoproteins (LDLs), on the other hand, are often called “bad cholesterol” because they allow cholesterol to build up on artery walls, increasing the risk for heart attack and stroke.

Experts speculate that HDLs protect against Alzheimer’s by clearing out specific proteins from the brain that trigger the disease’s symptoms.

For heart disease, HDL levels above 40 milligrams are considered protective. But when it comes to Alzheimer’s, “HDLs appear to protect only at these very high levels [of 55 milligrams or more],” says Dr. Christiane Reitz, the study’s lead researcher and an assistant professor of neurology at Columbia University’s Taub Institute for Research on Alzheimer’s Disease and the Aging Brain. Continue to read: wkbw.com
