A relationship between Toxoplasma gondii infection in womean and self-destructive behavior was found in a study of 45,788 Danish women between 1992-1995. Toxoplasma- specific IgG antibodies were measured in connection with childbirth, and Pedersen and colleagues concluded that mothers with T gondii infection had an increased relative risk of self-directed violence compared with noninfected mothers (1.53 vs 1.85; 95% confidence interval, 1.27-1.85). Increasing IgG antibody levels appeared to indicate increased risk. [101]
