Research by an Iowa State University scientist due to be published this month in the journal Proceedings of the National Academy of Sciences indicates that cholesterol-lowering drugs (statins) may lessen brain function.
The results of the study show that drugs that inhibit the liver from making cholesterol may also keep the brain from making cholesterol, which is vital to efficient brain function.
“If you deprive cholesterol from the brain, then you directly affect the machinery that triggers the release of neurotransmitters,”, said Yeon-Kyun Shin, the lead researcher. “Neurotransmitters affect the data-processing and memory functions. In other words – how smart you are and how well you remember things.”
Cholesterol is abundant in the tissue of the brain and nervous system. Myelin, which covers nerve axons to help conduct the electrical impulses that make movement, sensation, thinking, learning, and remembering possible, is over one fifth cholesterol by weight. Even though the brain only makes up 2% of the body’s weight, it contains 25% of its cholesterol.
We now know that the formation of synapses, or connections between neurons, is directly dependent on the availability of cholesterol.
“If you try to lower the cholesterol by taking medicine that is attacking the machinery of cholesterol synthesis in the liver, that medicine goes to the brain too. And then it reduces the synthesis of cholesterol which is necessary in the brain,” said Shin.
This study is yet another strike against statin drugs, which have numerous side effects and are not effective in reducing mortality for the vast majority of the population. Please see my recent article, The Truth About Statin Drugs, for more on why statins are probably not a good idea for you and your loved ones.
