THE RELATIONSHIP BETWEEN SCHIZOPHRENIA AND IMMIGRATION - ARE THERE ALTERNATIVES TO PSYCHOSOCIAL HYPOTHESES

Several recent studies have found markedly increased rates of schizophrenia among West Indian immigrants to the UK. Almost exclusively, authors have sought psychosocial explanations for these findings. This paper hypothesises that environmental causes, notably obstetric complications and perinatal infections, provide more plausible aetiological models, especially for the raised rates of schizophrenia among second-generation West Indian immigrants.
