Electroconvulsive therapy is a treatment for depression that uses electricity to induce a seizure.

How the Test is Performed    Return to top

Electroconvulsive therapy (ECT) is most often performed in a hospital's operating or recovery room under general anesthesia. Electricity is delivered to the brain for several seconds to cause seizure activity. Medicine is given to prevent the seizure from spreading throughout the body. Typically, ECT is given 3 times a week for a total of 6 to 12 sessions.
