It seems like we’re learning more every day about the delicate relationship between the body and the brain. Here’s something to add to the list of surprising findings: Drugs prescribed to lower cholesterol, called statins, seem to have an effect on a patient’s level of aggression, which depends, fascinatingly, on the sex of the patient. Women tend to become more aggressive, while men grow milder. Scientists hypothesize that this has something to do with the delicate balance between blood cholesterol, testosterone and serotonin. Since, according to a pharmaceutical survey organization more than 15 million Americans now take statin drugs, chances are you or someone you know is among them. Have you noticed a mood-altering effect? Do you find the connection between cholesterol drugs and aggression fascinating, or worrying? Share your thoughts in the comments.
