Electroconvulsive therapy (ECT), also called electroshock, is a psychiatric treatment in which seizures are caused by electricity in unconscious patients to treat illness.

The process is completed by placing electrodes on the sides of the patient's head (on either both or just one side) and sending a small electric current through the brain. This lasts for about half a second. The patient is also made unconscious before the treatment for safety reasons.

It is used mainly for people suffering from depression. It is generally only used when anti-depressant drugs have had no effect.
