The hypothesis that ECT produces selective effects on hypothalamic-pituitary activity was investigated by determining the effect of ECT on pituitary hormone release in nine depressed patients. After ECT there were massive and rapid increases in the plasma concentrations of nicotine- and oestrogen-stimulated neurophysin (NSN and ESN), prolactin (PRL) and adrenocorticotropin (ACTH), smaller increases in plasma luteinizing hormone (LH) and cortisol, a significant decrease in plasma growth hormone (GH) concentration but no change in plasma thyrotropin (TSH). There was significant attenuation of PRL responses with repeated ECT. The hormonal responses to ECT cannot simply be attributed to stress, since a similar pattern of increases in plasma hormone concentrations did not occur in psychologically normal patients in whom plasma hormone concentrations were measured during induction of anaesthesia and abdominal incision for cholecystectomy. Analysis of these hormonal responses in terms of the knowledge available on the neurotransmitter control of pituitary hormone release suggests that some of these hormonal responses to ECT may be mediated by the activation of serotonergic neurones, while others are probably due to direct stimulation of the neuroendocrine neurones themselves.

Reliable observation of ECT-induced hormone release requires that other processes that affect hormone levels remain constant and not obscure it. This article reviews principles and pitfalls in making such observations. Clinical applicability and limitations of measurements of prolactin, cortisol, oxytocin, vasopressin, and other hormones are described. Applications include elucidation of ECT physiology and seizure quality, comparison of ECT techniques, and description of illness severity. Accounting for each of these different effects can be needed to characterize any of them. An important but unrealized application of neuroendocrine measurement is prediction of the stability of individual ECT response.
