Abstract

Introduction: This study aimed to compare the infection of ToxoplasmaGondii and aggression in autism and normal children.
Methods: The research method was causal-comparative while it is considered as an applied research. The participants included (N=100) 50 autistic children and 50 normal children ranging from 3 to 12 years old; they were homogenous in terms of age, socio-economic status, the severity of the disorder, lack of physical and mental illness, and other criteria considered in this research. Then the researchers divided them randomly into two groups as experimental and control. Of each group, 5ml blood samples were collected to assess the prevalence of toxoplasma. To investigate the hypothesis, non-parametric Kai-Dwo test, Mann-Whitney U test, and Kruskal-Wallis test were used to analyze the data. The instruments were preschool aggression scale (Vahedi et al, 1387), and Elisa reder to essay the blood sample test.
Results: The results showed that children with autism had more pollution to Toxoplasma Gondii in comparison with the normal group.
Conclusion: Children with autism who had parasites were more aggressive than non-infected children who had autism (P=0/05).
