Electroshock—the controlled induction of a grand-mal seizure for the treatment of mental illness—is given to about 100,000 people every year in the United States. Although electroshock, or electroconvulsive therapy (ECT), is successful in treating severe mental illness in instances where other therapeutic methods have failed, the technique is underutilized because of its poor public image. Modern ECT is now considered to be safe and effective for the treatment of depression, schizophrenia, mania, catatonia and delusional states. on both temples.
