TL;DR
  • Understanding the ECT process reduces anxiety and uncertainty. If you or someone you know is considering electroconvulsive therapy, knowing exactly what happens during treatment alleviates fear and helps with informed consent.
  • ECT occurs under general anesthesia. You're completely asleep during the procedure. Anesthesia ensures you feel no pain and have no awareness of the treatment itself.
  • The procedure itself lasts only minutes. After anesthesia takes effect, the actual electrical stimulation lasts seconds. The induced therapeutic seizure is brief and controlled.
  • Recovery occurs in a monitored setting. You wake in a recovery area where medical staff monitor you as anesthesia wears off. Most people are ready to leave within an hour or two.
  • The step-by-step process is highly standardized. Modern ECT follows strict protocols: pre-treatment preparation, anesthesia induction, electrode placement, brief electrical stimulation, controlled seizure, and monitored recovery. Understanding each step demystifies the treatment.

If you or someone you know is considering electroconvulsive therapy (ECT), understanding exactly what happens during treatment can alleviate anxiety and uncertainty.

Here’s a simple step-by-step breakdown:

Step 1: Arrival and preparation

You'll arrive at a hospital or psychiatric clinic and meet your treatment team—typically including a psychiatrist, anaesthesiologist, and nurse.

Step 2: General anaesthesia

You’ll lie down on a hospital bed and receive general anaesthesia, ensuring you're asleep and pain-free during the procedure.

Step 3: Muscle relaxant

A muscle relaxant is administered to prevent physical movement during the seizure.

Step 4: Placing electrodes

Medical professionals place electrodes on your scalp, usually targeting the temporal cortex. Placement may be bilateral (both sides) or unilateral (one side), with unilateral placement causing fewer side effects.

Step 5: Administering the electrical current

A controlled electrical current (500-900 milliampere, lasting 1-6 seconds) is delivered, inducing a brief, controlled seizure lasting less than 60 seconds.

Step 6: Recovery begins

As the anaesthesia and relaxants wear off, you'll wake up in a recovery room. Initial confusion or mild disorientation is common but temporary.

Step 7: Post-treatment

Within an hour, most patients resume normal activities. Multiple sessions (usually 6-12) are typically needed for optimal results.

This structured process ensures ECT remains safe, controlled, and highly effective for treating severe depression.
