Scientific Reasons to Believe in Vampires, Werewolves & Zombies

To celebrate our new “Team Edvard” shirt, we’re re-running some of our favorite vampire stories this week.

Vampires

vampiresOne dark and stormy evening, Spanish neurologist Juan Gomez-Alonso was watching a vampire movie when he realized something strange; he noticed that vampires behave an awful lot like people with rabies. The virus attacks the central nervous system, altering the moods and behaviors of those infected. Sufferers become agitated and demented, and, much like vampires, their moods can turn violent.

Rabies has several more vampire-like symptoms. It can cause insomnia, which explains the nocturnal portion of the legend. People with rabies also suffer from muscular spasms, which can lead them to spit up blood. What’s stunning is the fact that these spasms are triggered by bright lights, water, mirrors, and strong smells, such as the scent of garlic. (Sound familiar?) After watching the Dracula movies a few more times, Dr. Gomez-Alonso felt compelled to continue studying vampire folklore and the medical history of rabies. Eventually, he discovered an even more profound connection between the two phenomena: Vampire stories became prominent in Europe at exactly the same time certain areas were experiencing rabies outbreaks. This was particularly true in Hungary between 1721 and 1728, when an epidemic plagued dogs, wolves, and humans and left the country in ruins. Gomez-Alonso theorized that rabies actually inspired the vampire legend, and his research was published by the distinguished medical journal Neurology in 1998.

The Madness of King George
Dr. Gomez-Alonso wasn’t the first scientist who tried to pin vampirism to a real illness. In 1985, Canadian biochemist David Dolphin proposed a link between vampires and porphyria—a rare, chronic blood disorder characterized by the irregular production of heme, an iron-rich pigment found in blood. The disorder can cause seizures, trances, and hallucinations that last for days or weeks.

As a result, people with porphyria often go insane. (Britain’s King George III, the one who inspired our founding fathers to start their own country, is thought to have suffered from it.) Porphyria sufferers also experience extreme sensitivity to light, suffering blisters and burns when their skin is exposed to the sun. Another symptom of porphyria is an intolerance to sulfur in foods. Which food contains
a lot of sulfur? That’s right, garlic.

Werewolves

teen-wolf-300In addition to explaining away vampires, medicine also has some answers for werewolves. In The Werewolf Delusion (1979), Ian Woodward explains that rabies may have also inspired the werewolf myth.

Rabies is transmitted through biting, and the dementia and aggression of late-stage rabies can make people behave like wild animals. Now, imagine that you are living in a village in medieval Europe and you see your friend get bitten by a wolf. A few weeks later, he starts foaming at the mouth, howling at the moon, and biting other villagers. Suddenly, that story your grandmother told you about the Wolfman sounds like a decent explanation for what’s going on.

Zombies

thriller.jpgZombies may also be creatures of science, at least according to Costas J. Efthimiou, a physicist at the University of Central Florida. In 2006, he attempted to explain the mysterious case of Wilfred Doricent, a teenager who died and was buried in Haiti, only to reappear in his village more than a year later, looking and behaving like a zombie. Efthimiou concluded that Wilfred was not the victim of a curse, but of poisoning. In the waters of Haiti, there is a species of puffer fish whose liver can be made into a powder, which has the ability to make a person appear dead without actually killing him. Wilfred may have been poisoned with the powder and then buried alive.

According to one of Dr. Efthimiou’s theories, once underground, Wilfred suffered from oxygen deprivation that damaged his brain. When the poison wore off and Wilfred woke up, he clawed his way out of the grave. (Graves tend to be shallow in Haiti.) Brain-damaged, he wandered the countryside for months until he ended up back in his village.

After Dr. Efthimiou published his explanation of the case, Dr. Roger Mallory, a neurologist at the Haitian Medical Society did an MRI scan of Wilfred’s brain. Although the results were nonconclusive, he found that Wilfred’s brain was damaged in a way that was consistent with oxygen deprivation. It would seem that zombification is nothing more than skillful poisoning.

  1. In an “Anthropology of Death” course, a guest lecturer told of his years-long stay in Haiti; he claimed that there were mob-like organizations that would deliberately poison people who disobeyed them or otherwise misbehaved, then retrieve them from their graves after they had suffered sufficient oxygen deprivation to make them compliant, if slow-moving, laborers. Therefore, Haitians will often barricade the graves of their loved ones, to prevent them from coming back.

  2. Nowadays people with porphyria are not likely to go insane. The standard treatment is keep a close eye on the iron levels in your blood, and when they are too high, you have blood drawn (comparable to a blood donation). You may have to limit your diet by not eating a lot of iron rich foods at one time, and you do have to limit your exposure to sun, but you can just wear a hat and not hang out at the beach. It’s really not that bad.

  3. In no way related to the science of the post, I just wanted to post: “THERE’S A TEEN WOLF ON THE COURT!!!”

    That is all.

  4. One of my Biology teachers in college was a snake digestive physiologist. As a grad student he was doing an experiment to try to find out why constrictor snakes have a cecum is they’re carnivores. During the course of this study, he discovered that after a large meal, snakes (and some other reptiles) can release large amounts of flammable gasses.
    He thought this might be a historic precursor to the widespread mythology surrounding dragons.

  5. …cecum if* they’re carnivores…

    sry

  6. There is also a form of anemia that causes vampire-like symptoms including sensitivity to sunlight; cravings for blood, dirt, and paper; sharp incisors, and more.

  7. both Wade Davis and Zora Neale Hurston wrote numerous books on the scientific explanation of zombies. click on my name to read more about them.
