In psychological analysis, schizophrenia is termed as a disorder to represent those who have failed to establish the integrity of their ego processes necessary to resolve conflict between the id and the demanding superego. Historically, the disease had affected many in the past and unfortunately in some cultures, victims were considered weak or possessed by evil spirits. Thus, they were treated with harmful methods. The heterogeneity of schizophrenic manifestations also makes the disease mistakenly known to be other forms of psychotic disorder. However, with several studies the disease is better understood but its prevalence is still massive to date (Bhugra, 2005) affecting more than 24 millions globally. Although, previous studies linked the disease with low socioeconomic status, Bhugra revealed that both genders of any status are afflicted with a proportion of 4 is to1, 000. While studies on its prevalence contributes to a better diagnosis and treatment of schizophrenia, in depth discussion of its causes and symptoms provides a more rounded knowledge of the behavior of schizophrenics.

The role of genetic factor in schizophrenia has started with the extensive studies of Franz Kallman involving twins in which he found out that the disorder is likely to occur in another twin if it existed with the other. Such finding accounts for more than 85% among monozygotic twins. Several succeeding researches also had proven the same findings employing sophisticated analysis (Kolb, 1977). It is further posited that children with schizophrenia in their family are 15 percent at risk of the disease than those without cases of schizophrenia in their families. In other studies, children with schizoid parents who were given for adoption show a higher incidence of schizophrenia.
