Electrophysiological and Hormonal Responses to Three Types of Electroconvulsive Therapy

Patients were treated with three different types of electroconvulsive therapy in random order in the first three sessions of their courses. Anaesthetic and muscle relaxants were administered in standard doses, and treatment applied a set time after bolus injection. Electroencephalographic recordings were undertaken before, during, and after treatment, and hormonal measures before and after. The responses to treatment differed between the three types of current in both EEG and prolactin measures. It is suggested that the quality of the convulsive response varies with different currents.
