I'd Google it for some facts before I'd judge it.
Here's a little about what I've found:
"The number of patients undergoing electroconvulsive therapy, as it's formally called, has tripled to 100,000 a year, according to the National Mental Health Association.
During an ECT treatment, doctors jolt the unconscious patient's brain with an electrical charge, which triggers a grand mal seizure. It's considered by many psychiatrists to be the most effective way to treat depression especially in patients who haven't responded to antidepressants. One 2006 study at Wake Forest University School of Medicine in North Carolina found that ECT improved the quality of life for nearly 80 percent of patients.
"It's the definitive treatment for depression," says Dr. Kenneth Melman, a psychiatrist at Swedish Medical Center in Seattle who practices ECT. "There aren't any other treatments for depression that have been found to be superior to ECT." ".
Apparently anti depressive drugs do not work for %30 of depression patients.
