Method of treating psychiatric disorders by inducing shock through drugs or electric current.

Shock was formerly induced by administering increasingly large doses of insulin until the patient was thrown into a brief coma; insulin-shock therapy was used for the treatment of schizophrenia. Electroconvulsive, or electroshock, therapy involves passing an electric current through the patient's head between two electrodes placed over the temples and thus causing a convulsive seizure; it was used for bipolar disorder and other types of depression. Both forms of shock therapy were developed in the 1930s; their use has declined since the introduction of tranquilizing drugs and antidepressants.

      method of treating certain psychiatric disorders through the use of drugs or electric current to induce shock; the therapy derived from the notion (later disproved) that epileptic convulsions and schizophrenic symptoms never occurred together. In 1933 the psychiatrist Manfred Sakel (Sakel, Manfred J.) of Vienna presented the first report of his work with insulin shock. Until the discovery of the tranquilizing drugs, variations of insulin-shock therapy (also called insulin-coma therapy) were commonly used in the treatment of schizophrenia and other psychotic conditions. With insulin-shock treatment, the patient is given increasingly large doses of insulin, which reduce the sugar content of the blood and bring on a state of coma. Usually the comatose condition is allowed to persist for about an hour, at which time it is terminated by administering warm salt solution via stomach tube or by intravenous injection of glucose. Insulin shock had its greatest effectiveness with schizophrenic patients whose illness had lasted less than two years (the rate of spontaneous recovery from schizophrenia also is highest in the first two years of the illness). Insulin-shock therapy also had more value in the treatment of paranoid and catatonic schizophrenia than in the hebephrenic types.

      Electroconvulsive, or electroshock, therapy, introduced in Rome in 1938 by U. Cerletti and L. Bini, has been widely used in treating disturbances in which severe depression is the predominant symptom. It has been particularly recommended for manic-depressive psychoses and other types of depression. The technique is essentially that of passing alternating current through the head between two electrodes placed over the temples. The passage of the current causes an immediate cessation of consciousness and the induction of a convulsive seizure. In general, electroconvulsive treatments are given three times a week for a period ranging from two to six weeks; some acutely disturbed patients, however, have been given as many as two or three treatments in a single day.

      Following a course of treatment there is usually an impairment of memory, varying from a slight tendency to forget names to a severe confusional state. The memory defect diminishes gradually over several months. Electroconvulsive therapy, like insulin shock, declined in use after the tranquilizing drugs were introduced.
