Catatonia is an abnormal psychological and behavioral state related to stress. The treatment strategy suggests the involvement of neuroactive steroids in its pathophysiology. We report a hospitalized patient with schizophrenia in whom a catatonic state occurred 7 times in 5.5 years. Blood levels of steroid hormones and adrenocorticotropic hormone (ACTH) were measured during the catatonic state and in the intervals between catatonic states (non-catatonic states). Cortisol and dehydroepiandrosterone sulfate (DHEAS) were significantly higher during catatonia than in the non-catatonic state. Cortisol significantly correlated with the ACTH level, whereas blood DHEAS and progesterone correlated only during the non-catatonic state. In addition, the cortisol to DHEAS ratios did not differ between catatonic and non-catatonic states. Although the correlating elevations of ACTH and cortisol implied activation of the hypothalamic-pituitary-adrenal axis (HPA-axis) in the catatonic state, DHEAS levels did not seem to increase in a manner dependent on the HPA-axis or the production of progesterone. The results suggest that the catatonic state was a neuroendocrinological state of HPA-axis activation with comparable increases in DHEAS levels.
