We tend to trust that doctors are on top of this whole "getting sick" phenomenon -- when we visit the hospital, we know that someone is going to be able to tell us what's wrong with us and how to fix it. But then there are some particularly unusual diseases out there that have medical professionals throwing up their arms and declaring "Shit, we guess it's witchcraft." Things like ...
5 The Sleeping Sickness
Imagine your spouse comes down with what you assume is a bad cold. But after getting worse over the next few days, she suddenly freezes like a statue, eyes blank and vacant, mouth contorted in a silent scream. She just lies like this, motionless, in a hospital bed. Then finally she wakes up, and acts like she's possessed by a goddamned alien body snatcher -- she's emotionless and distant at first, then starts gouging at her eyes and/or violently sexually assaulting people.
"I told you not to mix NyQuil and Ambien!"
It's not the first act of a horror movie, but a real, baffling disease that had doctors puzzled at the beginning of the 20th century. It's called encephalitis lethargica, or the sleeping sickness, and it struck the world as an epidemic just after the Spanish flu died down. Nobody has any idea where it came from or where it went.
It began with victims complaining of a sore throat, right before it escalated into a goddamned living nightmare, the victims afflicted with hallucinations and madness before their bodies ultimately locked up. While sufferers appeared to be asleep, they were actually fully conscious but unable to move. Many died during this stage, but for those who recovered, the nightmare was far from over.
"After discussing what a pain in the ass recovery will be, his father and I have decided to pull the plug."
Survivors of the sleeping disease suffered horrifying behavioral problems for the rest of their lives, becoming excessively violent and -- regardless of gender -- somewhat rapey. On top of all this, they became emotionally indifferent, unable to recognize, for example, the beauty of art. Ten years after the epidemic struck, new cases suddenly stopped appearing, its only legacy being the alien clones it left behind.
Nearly a century later, doctors still don't know what the hell was going on there, although they realize it was some kind of brain thing. One hypothesis is that the bacteria that caused the sore throat triggered an immune response that also destroyed parts of the brain, but many scientists still think a virus is the more likely culprit.
Seems a little lazy, Science.
In the meantime, the occasional case still crops up, to the scratching of many heads. Now try not to think about this the next time you get a cold, you poor bastard.
4 Jumping Frenchmen of Maine
Due to either a healthy sense of humor or an absolute lack of imagination, neurologists have settled on "Jumping Frenchmen of Maine disorder" to describe the bizarre condition first documented in the northern parts of Maine by George Miller Beard in 1878. That's when Beard noticed that a lot of the French Canadian lumberjacks of the region were, uncharacteristically, jumping and screaming like little girls at the slightest provocation.
"Here's where the t- HOLY PANTS-SHITTING CHRIST!"
And even weirder, victims dealing with Jumping Frenchmen aren't just easily spooked -- sufferers will enact basically any simple command, as long as you shout it at them suddenly, like "throw that beer" or "kick that stool" or even "punch that guy." It's apparently due to some heightened state of suggestibility, combined with an overactive startle reflex that turns victims into short-term robot slaves. And no, this is not a good thing to have when you are frequently found holding a giant axe.
The absurdly specific disease appears endemic to parts of northern Maine, and is largely restricted to those French Canadian lumberjacks, which suggests that it may be genetic, or else it's environmental, or somehow psychological, which all together rule out practically nothing. Some victims also display signs of echolalia (automatically repeating sounds they hear), which led some to believe that they suffered from either a form of Tourette's or being a giant parrot in a human-skin suit, but investigations show it doesn't appear related to either condition.
