| Description | Research on psychoses, especially schizophrenia, has been focusing on the period before and just after its onset. An interesting topic of research has recently become the influence of stress and dysregulation of the hypothalamic-pituitary-adrenal axis, which seems to play an important role in the etiopathogenesis of schizophrenia. The researchers are focused mainly on the role of cortisol, but the results are different. However, most studies suggest an increased basal cortisol level in patients with first episode of psychosis or people with a very high risk of developing psychosis, but on the other hand, a dynamic cortisol response to stress is reduced. Another hormone, aldosterone, which has been considered as mineralocorticoid without any function in the brain, appears to affect also psychological functions. There are studies showing the association of aldosterone levels related to clinical status (severity, course and outcome) in depressive disorder. In schizophrenia, there is a pilot study that has a different association with the severity of psychopathology of schizophrenia than in the case of depressive disorder, namely aldosterone serum levels were higher in patients with longer duration of schizophrenia and lower severity of psychopathology, as well as aldosterone / cortisol ratio. Because of lack of knowledge, further studies are needed to clarify the role of hypothalamic-pituitary-adrenal axis, cortisol and aldosterone as potential biomarkers in psychotic disorders, especially schizophrenia. |
