Toxoplasmosis… or maybe other parasites. Probably related to the reason why antiparasitics / antibiotics / antivirals sometimes help people with psychosis.


“Up to half of the world’s population is infected by toxoplasmosis, but have no symptoms.[7] In the United States, approximately 11% of people are infected, while in some areas of the world this is more than 60%.[3] Approximately 200,000 cases of congenital toxoplasmosis occur a year.[6] ” Wikipedia


*Study suggests small correlation between outdoor cat ownership in childhood and an increased risk of psychosis in males. There are so many other possible factors here with such a limited questionnaire that I find it a bit difficult to take anything from this study other than speculative coincidence.


This has been kicked for years… still nothing conclusive. The article itself said 30% of the population is infected…. So…. What are the base rates vs psychosis and have they changed over the years?


Headline suggests that it’s really toxoplasma gondii infection manifesting in males.
