A cat parasite might be responsible for outbursts of anger in humans. University of Chicago researchers say toxoplasma gondii is part of their broader effort to improve diagnosis and treatment of people with recurrent bouts of extreme anger such as road rage.
Toxoplasmosis is a parasitic disease that is most commonly transmitted through the feces of infected cats, according to Scientific American. People can contract it from handling cat litter.
It can also be found in undercooked meat or contaminated water. The parasite that causes it, toxoplasma gondii, is carried by nearly 30 percent of all humans and in most cases is considered relatively harmless. The Centers for Disease Control and Prevention estimates more than 60 million people in the U.S. may have it.
However, in some people, the researchers found a link between the cat parasite and Intermittent Explosive Disorder (IED), a psychiatric disorder characterized by recurrent, impulsive, problematic outbursts of verbal or physical aggression that are disproportionate to the situations that trigger them.
