Do forgive my lack of blogging for the past couple of days. I’d be tempted to pass the blame off onto Christmas and all that, but then, that would just be lazy. Which is, in fact, the primary reason for my lack of posting. So, to compensate, here is my longest blog post to date. There.
As you can surmise by this post’s title, this is a rather intriguing subject I’m writing about, here. A reader with whom I’ve been having an interesting discussion regarding pedophilia, morality, and the likes, has brought my attention to a couple of stories on how neurological impairment (aka brain damage) and its effects on those who have it, specifically regarding impulses, inhibitions, and sexuality. These cases bring up very intriguing questions on the neurology of morality, and the nature of free will.
The first case is one of the most peculiar stories you’ll ever hear in the realms of neurology and psychology. Imagine a perfectly normal middle-aged man who has a career and a family, a man who has normal interests in sex and shows no signs of any deviancies. Then, virtually overnight, he becomes addicted to sex (a condition known as “hypersexuality”) and becomes entrenched in child pornography. He even tries to molest a prepubescent girl, despite having shown absolutely no sexual interest in children for the first four decades of his life. In other words: a perfectly normal 40-year-old man suddenly turned into a pedophile and a would-be child molester, for no apparent reason (at least at first).
Now, people don’t just become slaves to hyperactive sex drives and start groping children after having lived what is arguably the first half of their lives without having shown the slightest impulses to do so. Yet, this is what happened to the man who is the subject of this first story. However, this is only a partial medical mystery, for neurologists have identified the precise cause of his behavioral issues: a tumor in his prefrontal cortex, the part of the brain responsible for controlling one’s impulses and inhibitions (ie. self-restraint).
CHARLOTTESVILLE, VA -- He was a schoolteacher, a husband, a father. Then he became a pedophile preoccupied with sex.
Doctors who treated him at the University of Virginia hospital in 2000 believe that the man's powerful sex addiction was caused by an egg-sized tumor in his brain.
"It turned out he was a guy who had made it into his 40s without having any problem with this," said Dr. Russell Swerdlow, a UVa associate professor of neurology. "He had a brain tumor that was damaging the part of the brain that controls impulse."
