Toxoplasmosis is a known parasite that over 90% of patients with schizophrenia test positive for. (According to research etc) My son was one of those. I took him to a ND in Mexico who gave him a prescribed compound of Gallium. Within 7 days he was better. He is no longer on any medications. I suggest you check into this. If you have any questions feel free to ask or reply but this should be some good info. Good luck and God Bless
