According to a recent study, conducted by the Centre for Cellular and Molecular Biology (CCMB) and published by the American Chemical Society, continuous use of statin drugs may cause depression.
The CCMB study discovered that statins might have a negative effect on serotonin levels in the brain. Serotonin acts as a neurotransmitter that carries messages between brain cells. It also plays an important role in regulating mood, as well as behaviour. The researchers found that long-term use of statins changes the function and structure of serotonin receptors (cells). When the researchers added cholesterol to the cells, which had been treated with statins, it restored the normal function of the receptors. They concluded that there is a strong link between statin use (which lowers cholesterol) and mood disorders, which can lead to depression in a small number of people, who are genetically inclined towards the condition. Low serotonin levels are also linked to anger, sleep loss and other problems.
However, if you look at previous studies, the link between depression and statin use is not that small or marginalised…
Earlier this year, two separate studies challenged mainstream medicine’s belief that lowering your cholesterol is always a good thing. In fact, both studies suggested that statins might affect intelligence, cause depression and even raise the risk of suicide.
One of the studies, conducted at Iowa State University, in the US, suggested that statins inhibit the vital process during which cholesterol is used to produce serotonin in the brain. According to the researchers, when brain cells are deprived of cholesterol, they are five times less effective at releasing serotonin. Their findings were published in the highly respected journal Proceedings Of The National Academy Of Sciences.
These findings are reinforced by another study, which found that men with a combination of low cholesterol and depression are seven times more likely to die prematurely from suicide, accidents and other unnatural causes than men with depression and normal cholesterol levels.
The research, lead by Dr Joseph Boscarino, of the American Geisinger Institute, followed nearly 4,500 Vietnam veterans over a 15-year period. They concluded that their disturbing findings may be due to low blood cholesterol levels reducing the brain’s ‘feel-good’ chemical messenger, serotonin.
A case in point is the implication of statin use in the suicide of London teacher Allan Woolley. After being prescribed the statin drug simvastatin, Mr. Woolley complained of blackouts, insomnia and nightmares before he killed himself by standing in front of a train, in April 2007. His family and friends said his death was completely out of character. The coroner ruled that the drug ‘was involved’ in his suicide.
Furthermore, Irish doctors have reported that cholesterol levels are significantly lower in people who have been admitted to hospital after harming themselves.
Animal studies also support these findings: studies of captive monkeys reveal that they become abnormally aggressive when put on low-fat diets, which are low in cholesterol. And studies on mice indicate that cholesterol may help the brain to suppress reckless impulses.
Hair-raising findings like these should be enough reason to rewrite the public health message, which if based on the real facts, should read: moderation in all things – including lowering cholesterol levels.
Perhaps this will prompt government agencies to reconsider their current recommendation that maximum ‘healthy’ total cholesterol levels should be less than 5.0 millimoles per litre of blood (mmol/l). Especially since research suggests that the harmful effects of too low cholesterol levels is estimated to be at the ‘danger threshold’ when just below 4.0mmol/l.Here's to keeping your heart strong and healthy
