A Brain Parasite Might Be Making Us Angrier - Newsy

153 ratings | 10809 views
Transcript: More and more studies are hinting that our brains might not be completely our own. The parasite Toxoplasma gondii, Toxo for short, may be changing human behavior — perhaps even making us angrier and more aggressive. Toxo is one of those frightening parasites capable of controlling its hosts. It reproduces in the stomachs of cats, and it's always trying to get back inside one. So when an animal, usually a mouse or rat, becomes infected through contact with cat poop, the parasite gets into the rodent's brain and literally rewires it. Basically, it makes its host fall in love with cats so it'll go find one and get eaten. Humans can contract the parasite, too, through eating unwashed vegetables or undercooked meat. And, obviously, through cat poop. But while it can pose problems for pregnant women or people with weakened immune systems, it's generally not considered a threat to human health. That's lucky because Toxo is incredibly common. Around a third of people in the world and more than 1 in 5 in the U.S. are infected, and the vast majority never suffer any ill effects. At least, that's what we thought. Over the past decade, studies have linked Toxo to higher rates of schizophrenia, bipolar disorder, depression, suicide attempts, risk taking, impulsiveness and now, aggression. A recent study found people with the parasite score higher on anger and aggression tests, and people with anger disorders are twice as likely to have the parasite than you'd expect from chance alone. What does all of this mean? Well, it's too early to say. None of the studies so far are considered proof that Toxo is driving changes in human behavior. Its effects might be overhyped due to its creepiness. But because it's so common, if infection really does raise the risk of mental illness even slightly, that could translate to tens of millions of cases.

The truth is humans have many parasites on our skin, in the intestinal tract, in the nasal cavity sorry to say we are just animals too.
I thought it did the opposite since it rose dopamine and reduced fear.

How do they get there? Ets?

That’s another hit to the idea that we think we have ‘free will’ You just find out, your brain is simply a host to other organisms that manipulates, effects hormones, adrenaline and other processes that effect your behavior. To what lengths is it subconscious and you’re not aware ought to worry you. Who can say there are not extremely more powerful strains, that have evolved for millions of years that could overwhelm your bodies defenses like other viruses and bacteria?

It's too bad members of the US Federal government aren't more aware of this problem. Solving it could reduce wreckless driving and violent conflict such as school shootings. A viable vaccine could save countless lives, prevent a large percentage of mental illness and protect everyone's feline companions. Pharmaceutical companies could make billions by preventing the many horrible things caused by T. gondii as opposed to marketing ineffective medications to treat chronic conditions.
No, it won't stop school shootings, but it will definitely stop more car accidents since toxoplasmosis is also said to reduce response times.

The most accurate video on Toxoplasma that I've seen.

Would be nice if psychiatry took things like this into consideration instead of JUST focusing on neurotransmitters & emotions. Head trauma, infections, inflammation & many other biological processes can contribute to mental illness but are largely ignored.

It's right in front of their noses. Toxo eats GABA, the brain's inhibitory neurotransmitter. My phone even knows gaba, auto-corrects to all caps. It's like, psychiatry 101. The fact they ignore T. Gondii is spooky. Unless they have it too.

Chris Courtney It's not only in cats tho. The turn crazy cat lady came about because they have so many cats.

Garlic is a good expeller of parasites and the like. Apparently the liberals have toxo in their tofu

Its not only involved with cats, its everywhere for example chickens will eat the same things as mice.

A cat is only infectious for 2 weeks. Other sources are much more likely.

I kill cats, no matter if I'm serious or not. You cat lovers enjoy raging at me.
Kelly J (7 months ago)
You have problems. Get help.
MsNooneinparticular (8 months ago)
I hope you're trolling. Killing innocent animals is a crime & you're a psychopath if you do it.

What the hell are these sickos doing with cats to contract this!

"Colleagues at John's Hopkins University have estimated that every square foot of soil in the United States contains from 1 to 400 oocysts" We're doomed.
MsNooneinparticular (8 months ago)
Oh, I dunno. "Sick" stuff like changing litter boxes or simply living with cats indoors who walk across surfaces after stepping in their litter box... People don't realize how easy it is to ingest feces. Human feces is on nearly every surface in public places. It's how norovirus & other stomach bugs are spread. Those 'wash your hands' signs aren't just a fun suggestion. If you live with cats, you're bound to come in contact with their feces & urine at some point....even if it's only microscopic amounts. Same with most other animals.
coming in contact with their shit that's what they're doing

straight from the tap or the box? if from the box, at the very least use chop sticks, we must remain civil.

1/3rd of the human population has it, so you're not alone.

Me too. I studied it casually for about a year, via google alert.

ok scare the crap out of us with out telling us what to do about it

Olive leaf extract daily, Colloidal silver, Apple cider vinegar, a shot a day, reduction in meat consumption and acidic foods, reduction or removal of alcohol, drugs, and fast food. Stress less exercises such as TACFIT, 3 liters minimum of water a day. Focused Breathing exercises for 15 minutes a day, one car space between you and the one to the front to reduce cortisol spikes while driving. Removal of cats and the cleaning of rugs. Washing your fruit and veggies clean, use Garden of Life products instead. All of these things combined will make your corporeal shell rather hardened against Toxo. However, if you have Toxo, it will likely interfere with your ability to take these steps, and instead will cause you to ridicule them and call them quacky. I have helped others fix their toxo issue, but it helped that they knew me in person, and see how I live. Toxo is not in the brain so to say, but it does influence it. Its primary impulse is upon the R-Complex brain, and interfering with signals to the Neo-cortex. Its by way of chemical inhibitors. If you structure the lifestyle I said above, it will not be able to remain in you as a host, because it requires an acidic environment, and a poor immune system. For increased fighting of it, an extra step is semen retention, which in 7 days, becomes recycled increasing testo in men by %47 percent. Men with low testo and passive demeanor, tend to have toxo. Well, there you have it, a solution toxo pretty much prevents from activating because it is living contrary to the dictates of toxo, which aims to make you a aggressive/pascified, self destructive/ or risk taking, depressed and inactive, neuroticsuicidal animal.
