The traditional neurodevelopmental hypothesis of schizophrenia emphasizes the interaction among genetic susceptibility, early environmental insults (e.g., obstetric complications), and psychosocial factors. Recently, in addition to the development of neuroscience and genetics, psychosocial factors drew particular attention, and some experts extended the neurodevelopmental model with a social developmental component. In this paper, the author reviews recent findings regarding the link among schizophrenia, childhood and adolescent trauma, and immigration. Beyond some current epidemiological results, the author also outlines the models integrating attachment theory and neurocognition and the revised version of the neurodevelopmental hypothesis.
