Prenatal And Neonatal
Neonatal and prenatal complications have been shown to occur with greater statistical frequency in persons with schizophrenia than controls. This paper provides an overview of literature relevant to this topic. Neonatal and prenatal complications related to schizophrenia are broken down into four general areas of research: family history, gestational insults, obstetric complications, and neurodevelopmental deficits. Although this research is moving forward, prospective studies have only recently been established; therefore, investigators have been hindered by the difficulties related to retroactive data assessment. This paper reveals some of the areas in which conflicting research has resulted and the attempts researchers have made to overcome these conflicts. In addition, the recent hypothesis of three etiological subgroups of schizophrenia is discussed, as well as areas of research leading from this data.
Undoubtedly, family history is the most predictive variable of schizophrenic risk. Children of mothers with schizophrenia have a sixteen percent (16%) risk of developing chronic schizophrenia, compared to a one percent (1%) risk in the general population. Chances of schizophrenia or a related spectrum disorder become even greater if both parents are diagnosed (Olin and Mednick, 1996). Numerous twin studies diagnosed with schizophrenia have been used to demonstrate the genetic link. However, twin studies have also evidenced environmental effects – for example, researchers were unable to locate matching phenotype expressions for the genetics hypothesized in twins concordant for schizophrenia (Proceedings of the Fifth International Congress on Schizophrenia Research, 1995). Such discrepancies highlight the complex, multi-determined etiology associated with this disorder.
