Hypothalamic–Pituitary Function in Depressive Illness: Insensitivity to Hypoglycaemia

Abstract

The insulin tolerance test was performed in 16 severely depressed patients on admission to hospital and after treatment with electric convulsion therapy. The mean plasma cortisol response to hypoglycaemia was significantly impaired before treatment, particularly in the patients who also showed resistance to dexamethasone suppression. The results are consistent with hypo- thalamic-pituitary insensitivity to hypoglycaemia in these subjects. © 1969, British Medical Journal Publishing Group. All rights reserved.
