Mind-Altering Cat Parasite Linked To Schizophrenia in Largest Study Yet (sciencealert.com)

Scientists claim they have found new evidence of a link between infection with the protozoan parasite, Toxoplasma gondii, and schizophrenia, in what is described as the largest study of its kind. From a report: T. gondii, a brain-dwelling parasite estimated to be hosted by at least 2 billion people around the world, doesn't create symptoms in most people who become infected -- but acute cases of toxoplasmosis can be dangerous. Healthy adults are generally thought to not be at risk from T. gondii infections, but children or people with suppressed immune systems can develop severe flu-like symptoms, in addition to blurred vision and brain inflammation.

Pregnant women need to be careful too, as the parasite can cause foetal abnormalities or even miscarriage. Aside from the known physiological dangers, however, the stranger and more ambiguous risks associated with the parasite remain largely hypothetical -- although a huge body of research suggests something weird is going on. Causation remains very much disputable, but the brain-dwelling parasite -- commonly carried by cats and present in their faeces -- has been linked to a huge host of behaviour-altering effects.

Virtually all warm-blooded animals are capable of being infected, and when T. gondii gets inside them, unusual things happen. In rodents, animals seemingly lose their inhibitions, becoming more exploratory and losing their aversion to cat odours.

    Since it's psychoactive, it's not surprising that it has such effects on humans.

    This is similar to the rabies virus, which causes dogs to bite anything and everything (the virus is present in saliva) and actually has the same effect on humans. In humans, the end result is hallucinations, confusion, and aggression - probably what dogs are going through before they die of rabies.

    The active infection is fairly easy to treat, but there is no known way yet to eradicate the latent, encysted infection.

    Psychiatric researchers have known about this problem for a while, and they've even done a few controlled trials to see if schizophrenics etc. improve when given anti-toxoplasma agents. The trials were all failures. As more than one reviewer has pointed out, the failures were not surprising, because the anti-toxo agents are known to be ineffective against latent infection.

    >> In rodents, animals seemingly lose their inhibitions, becoming more exploratory and losing their aversion to cat odours.

    Huh.. One can see how adaptive evolution would favor cats who can put the parasite out there without being affected by it themselves. Cats benefit when rodents get daring in their presence. More significantly, it also makes humans crave their presence and care for them, if only in a very basic sense. Now that's an effective adaptation!
