Electroconvulsive therapy

Definition:

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

Alternative Names:

Shock treatment; ECT

How the test is performed:

Electroconvulsive therapy (ECT) is most often performed in a hospital's operating or recovery room under general anesthesia. A very brief shock, typically lasting several seconds, is administered to the head to induce a short seizure. Medicine is given to prevent the seizure from spreading throughout the body. Typically, ECT is given three times a week for a total of 6 to 12 sessions.

How to prepare for the test:

Because general anethesia is used for this procedure, you will be advised to not eat or drink before ECT.

Ask your health care provider whether you should take any daily medications in the morning before ECT.

How the test will feel:

Some people report mild confusion and headache following ECT. Hospital staff monitor the patient closely after the procedure to ensure complete recovery.

Why the test is performed:

ECT is a highly effective treatment for depression. It is also used to treat bipolar disorder, catatonia, and some psychotic disorders.
