What role infectious agents play in the causation of psychotic disorders? To investigate this area, we have aimed to investigate the relationship between Toxoplasma gondii and psychotic disorders. A hospital-based cross-sectional study is designed. IgM and IgG antibodies to T. gondii in patients with psychotic disorders will be measured and presented in result. Seropositivity rates will be compared with first-degree relatives and healthy volunteers. Also, types of psychotic disorders and seropositivity rate will be compared. Here, we are presenting the study protocol with implications toward a brain-based diagnostic system and novel treatment approaches.
Keywords: Toxoplasma gondii; diagnostic system; psychotic disorders; seropositivity rate.
