The primary aim of this study was to analyze the impact of schizophrenic disorders on pregnancy outcomes. The secondary aim was to briefly analyze the potential role of antipsychotic treatment on influencing pregnancy outcomes in expectant mothers with schizophrenia. We searched the MEDLINE, PsycINFO, and Science.gov databases for articles published in English from January 1980 to January 2019. We used the following search terms: ‘schizophrenia’, ‘motherhood’, ‘pregnancy/foetal/neonatal outcomes’, and ‘birth defects’. The reference lists of retrieved articles were also consulted to find additional pertinent studies missed in the electronic search and/or those published before 1980. Data were extracted from articles that provided primary data on the impact of maternal schizophrenia spectrum disorders on obstetrical and perinatal outcomes. After excluding duplicates, 35 articles were identified. Systematic reviews were searched on the same databases to briefly assess the effects of antipsychotics on pregnancy outcomes. The reviewed studies showed several limitations. They were published during a time range from the early 1970s to 2019. During this period, there were significant changes in the diagnostic criteria for schizophrenia. Moreover, such studies showed no homogeneity in the investigation of potential confounders. Most importantly, no research has differentiated the effects of maternal illness on pregnancy, fetal, and neonatal outcomes from those associated with antipsychotic treatments. Thus, it is not surprising that such studies show conflicting results. Despite such limitations, in managing pregnant women with schizophrenia clinicians should consider an integrated approach that includes: antipsychotic treatment, psychological treatment, optimal dietary approaches for prevention of excessive weight gain and gestational diabetes, meticulous gynecologic and obstetric surveillance, and social and occupational support.
