Circulating Neuroactive Steroid Levels in a Patient With Schizophrenia Who Showed Periodic Catatonia.

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.
