We know that anabolic-androgenic steroids can cause heart problems, but how to they affect your brain? Here’s the science.
The general public usually thinks of steroid users as monosyllabic knuckleheads. They’re handy friends to have around when you need help moving your sofa, but not the guys you want on your team during trivia night.
Well, I know plenty of chemically augmented folks who defy this stereotype, but science has hinted for years that anabolic-androgenic steroid use CAN negatively affect the brain.
One previous study discovered that heavy steroid customers reported extra reminiscence issues and points with “govt functioning” – the psychological processes that show you how to to concentrate, plan and execute duties, and coordinate information. However that was a examine utilizing on-line surveys, which could be iffy.
Now, researchers have studied this extra carefully. What they discovered is alarming.
The New Examine
Researchers rounded up 85 previous and current steroid-using men along with 64 non-steroid users to act as controls. They shoved them all into an MRI machine, scanned their brains, and gave them a comprehensive neuropsychological battery of tests.
Along with measuring the regional cortical thickness and arealization of their brains, the scientists studied the participants’ fine motor speed, speed of processing, learning ability, working memory, executive functioning, and problem-solving skills.
The steroid users were indeed monosyllabic knuckleheads.
Okay, not quite. But they did perform worse in several cognitive domains, like speed of processing, working memory, and problem solving. Generally, their cerebral cortexes weren’t as thick. (Thickness in this brain area is associated with intelligence in other studies.)
Also, the longer the person had been using steroids, the worse his memory seemed to be. Short-term users still had issues, but they faired better than long-term users.
Summary: Prolonged use of high-dose anabolic steroids does seem to lead to poor brain health and handicapped cognition. So, add this to the list of drawbacks.
How To Use This Data
A lot of people think that steroids are dangerous, society-wrecking drugs on par with heroin and meth. Those people are wrong. But so are the folks who say that steroids, when “used wisely,” are perfectly safe.
They’re not, at least when it comes to bodybuilding dosages used for prolonged periods. Your heart doesn’t prefer it, and, apparently, neither does your mind.
