Objective: Schizophrenia is a significant and common disorder. In neural development, it has been noted that prenatal ve perinatal disruptions result in neuropsychological deficits and these deficits might result in early-onset behavioral problems and criminal behaviors. Taking all these previously completed studies into consideration, we have designed a study to find out whether or not there would be any difference caused by previously acquired viral infections between criminal patients and non-criminal ones. On the other hand, this study compares the socio-demographic characteristics. Methods: Two groups from criminal services and acute psychiatry services participated in the study; the first group consists of 97 male schizophrenic patients with criminal acts and the second group consists of 105 male schizophrenic patients with no criminal acts. ELISA method was used to detect HSV 1-2, and CMV infections. Sociodemographic characteristics of the patients were obtained by scanning patients' files and/or consulting their relatives. Results: The present study was conducted with 202 male patients at the ages of 20 to 76 with a mean age of 40.36 +/- 11.33. A logistic regression analysis was conducted by assuming the variables observed as statistically significant or near statistically significant effects as independent variables and the crime commitment status as a dependent variable, in univariant committing crime analyses. Conclusions: These results indicate a statistical significance in some parameters among sociodemographics of schizophrenic patients with criminal acts and without criminal acts as well as non-existence of any significant association between HSV 1-2, and CMV infections and crime commitment in schizophrenic patients.
