'Good' cholesterol may help to prevent Alzheimer's disease in the brain

Dr. Hussein Yassine, one of the study's co-authors, said, "This is the first time that tiny HDL particles in the brain have been counted."

Medicine costs, doctor's fees, and lab testing are all covered for $299 each month.

Yassine and his colleagues looked studied the contents of high-density lipoproteins (HDL), also known as "good cholesterol,".

A higher quantity of tiny HDL particles in cerebral fluid was connected to two crucial markers .

They might protect against Alzheimer's disease, according to the study.

Better performance on memory and thinking (or "cognitive") abilities tests is one indicator.
