Schizophrenia and Its Genetic Basis: A Review Study

Background: Schizophrenia is a devastating mental illness that interferes with the patient’s social and occupational functioning and impairs the patient’s life. Methods: The research method is a Review Study based on library, documentary and field studies. Results: Studies indicate the bio-genetic basis in the etiology of schizophrenia disorder; however, the mystery of the formation of this disease is still somewhat unknown. Parents’ age is considered as an effective index on incidence of children to psychotic disorders. Studies show that parents’ higher age is associated with having children with schizophrenia and mostly parents, who have children with schizophrenia under the legal age, do not live with their child. Conclusion: This study was a review study, the results of which can be useful in planning preventive interventions.
