The effects of stress on hypothalamic-pituitary-adrenal (HPA) axis function in subjects with schizophrenia

Over the last few decades, evidence has been emerging that the pathogenesis of psychiatric disorders such as schizophrenia can involve perturbations of the hypothalamic-pituitary-adrenal (HPA) axis. Variations in the manifestation of these effects could be related to the differences in clinical symptoms between affected individuals as well as to differences in treatment response. Such effects can also arise from the complex interaction between genes and environmental factors. Here, we review the effects of maternal stress on abnormalities in HPA axis regulation and the development of psychiatric disorders including schizophrenia. Studies in this area may prove critical for increasing our understanding of the multi-dimensional nature of schizophrenia. Further research in this area could ultimately lead to the development of improved diagnostics and novel therapeutic approaches for treating this debilitating psychiatric condition.
