A new study shows a parasite found in cast may cause impulsive aggression in humans.
The parasite is called toxoplasma gondii. The parasite lurks around in its host’s brain and is most commonly transmitted through the feces of infected cats.
People are exposed to the parasite through changing a cat’s litter box, eating undercooked meat, or drinking contaminated water.
The parasite can be found in almost 30 percent of humans, but doctors say it is relatively harmless.
However, some research published in the Journal of Clinical Psychiatry said there is a link between the parasite and (IED) Intermittent Explosive Disorder.
Some signs of IED usually include sudden outbursts, verbal or physical aggression, and anger that doesn’t fit the situation.
The study showed people with IED were more than twice as likely to test for the cat parasite.
