Toxoplasmosa Gondii Linked to Personality Changes


Toxoplasma Gondii, a parasite theorized by some to cause schizophrenia, has been found by researchers publishing in the European Journal of Personality to be linked to an increase in extroversion and a decline in conscientiousness. The parasite, which causes rodents to lose their fear of predators (resulting, in turn, in more reproduction of the parasite) has also been associated with a higher rate of traffic accidents in humans.

Article → Note from Kermit Cole, “In the News” editor:
While the theorized link between schizophrenia and T. Gondii (and it does appear to be true, according to this article, that there is a higher rate of infection among people with the diagnosis – though this could just as easily be a result of behaviors associated with the diagnosis as it may be of the parasite causing the behaiors), my interest in including this here is that; if it is true that the parasite can increase the rate of behaviors that are sometimes associated with a schizophrenia diagnosis, then it could be that the T. Gondii/Schizophrenia research has been, in essence, barking up the wrong tree (and at the wrong cat).
