It is widely accepted, however, that the various phenotypes of the illness arise from multiple factors, including genetic susceptibility and environmental influences.2,8, One explanation for the development of schizophrenia is that the disorder begins in utero.6 Obstetric complications, including bleeding during pregnancy, gestational diabetes, emergency cesarean section, asphyxia, and low birth weight, have been associated with schizophrenia later in life.2 Fetal disturbances during the second trimester—a key stage in fetal neurodevelopment—have been of particular interest to researchers.3 Infections and excess stress levels during this period have been linked to a doubling of the risk of offspring developing schizophrenia.3, Scientific evidence supports the idea that genetic factors play an important role in the causation of schizophrenia; 2 studies have shown that the risk of illness is approximately 10% for a first-degree relative and 3% for a second-degree relative.9 In the case of monozygotic twins, the risk of one twin having schizophrenia is 48% if the other has the disorder, whereas the risk is 12% to 14% in dizygotic twins.9 If both parents have schizophrenia, the risk that they will produce a child with schizophrenia is approximately 40%.9, Studies of adopted children have been conducted to determine whether the risk of schizophrenia comes from the biological parents or from the environment in which the child is raised.
