Immediate increases in plasma prolactin and neurophysin but not other hormones after electroconvulsive therapy.
Plasma prolactin, growth hormone, cortisol, luteinising-hormone-releasing hormone (LHRH), thyrotropin-releasing hormone (TRH), and nicotine and oestrogen stimulated neurophysin (NSN and ESN) were measured before and for 6 min after electroconvulsive therapy (ECT) in eight women with severe electroconvulsive therapy (ECT) in eight women with severe depression. Plasma concentrations of NSN and ESN had increased significantly (as much as 10-fold for NSN) within 1 min of the seizure, and concentrations of prolactin had increased within 2-4 min after the seizure. Whereas plasma prolactin and ESN either continued to increase or remained raised throughout the 6 min after seizure, the concentrations of NSN fell to reach a value at 6 min that was approximately 50% of the maximum. There were no increases in any of the other hormones or peptides within the 6 min period under study. Thus ECT has selective effects on hormone release which cannot be attributed simply to a generalised release of pituitary or hypothalamic hormones in response to brain stimulation and/or stress.
