Electroconvulsive therapy (ECT) is now a widely accepted treatment for severe depression, psychosis, and catatonia.

With the use of muscle relaxants and anesthesia, patients waken and wonder whether they've had the treatment yet.

It has been approved by the National Institute of Mental Health, the American Medical Association, and the U.S. Surgeon General.

ECT will not be as common as medication for depression because it is more costly and complex to administer.
