Cat Parasite May Increase Risk of Suicide In Humans

An anonymous reader writes "Researchers at the University of Maryland analyzing meticulous data collected by Danish authorities have identified a positive correlation between suicides among women with infection with the fairly common parasite T. gondii. Carriers were 53 percent more likely to commit suicide in a sample of 45,000 Danish women monitored for over a decade (researchers believe that the same correlation likely exists for men). Increased susceptibility to schizophrenia and bipolar disorder was also discovered. The physiological mechanism has not been determined, although some speculation centers around changes to dopamine levels. Two intriguing aspects were noted: 1) human infection often (but not always) begins by exposure to cats carrying the parasite, for example, by changing an infected animal's litter; and 2) the parasite spreads itself by infecting the nervous system of rodents, causing them to become suicidally attracted to feline odors which will increase the likelihood of their hosts being eaten by cats, whose digestive tracts provide the preferred environment for parasite reproduction."

      The article is about human infections, so you might want to avoid eating humans. If you get infected, it will lower the dopamine level in your brain, and then you will get hungry for . . . another human brain . . .

      I have actually eaten cat. Many years ago, I was in the red light district of Panama City (Fourth of July Street) with some fellow jarheads, and some guy had a "monkey" roasting on a spit. So we each bought a slice. We were eating as we walked along, and I noticed a young woman laughing at us. I asked her what was so funny.
      She smiled asked "Do you know what you are eating?"
      "Monkey meat."
      "Nope. It's an alley cat."
      Anyway, it tasted like chicken.

      Wash your hands.

      If you are a cat owner, and you can't handle the simple fact that you are dealing with feces and vomit every day without a proper hygiene protocol, something has already gone wrong.

      I've got cats and I don't handle their feces every day. I let my neighbourds do that when the cats go and crap in their rosebeds.

    Do the crazy cat ladies have cats because they are crazy, or are they crazy because they have cats?

    The parasite also causes decreased sexual inhibition. Translation: It makes women sluttier. No corresponding effect was found in men. Of course, this effect isn't as widely documented for obvious political reasons...

    That is because in men there is no sexual inhibition to effect.
