Study links low HDL levels to memory loss

In a new study of nearly 3,700 adults, doctors recited a list of 20 words and asked participants to write down what they could remember.

People with low HDL performed 27 percent worse on the test at age 55. By age 60, the performance gap widened by 60 percent.

Currently there are no approved drugs to boost HDL for memory. Researchers recommend eliminating trans fat from diets, eating healthy fats and getting regular exercise.

The American Heart Association has more on this research.
