ECT — electroconvulsive therapy — is wrapped in more mythology than any other procedure in psychiatry. The image from One Flew Over the Cuckoo's Nest is glued to the word, even though the actual procedure today looks and works nothing like that.
This piece isn't about whether "a psychologist is better." It's about which situations ECT is genuinely indicated for, which it isn't, and what questions to ask if the choice has landed on you or someone close to you.
What ECT is (without the myths)
ECT is a procedure in which, under general anaesthesia and muscle relaxants, a brief electrical pulse is passed through the brain to trigger a controlled seizure. The whole thing takes about 5–10 minutes; the seizure itself is under a minute, and because of the muscle relaxants, visible convulsions are minimal.
The exact mechanism isn't fully understood. The leading theory is that a series of these seizures rebalances neurotransmitter systems and plasticity in mood-related regions. It's one of the most effective treatments in psychiatry for certain conditions — a major meta-analysis in The Lancet found that for severe depression, ECT works faster and more powerfully than antidepressants.
Effectiveness isn't an argument for using it on everyone. It's an argument for not crossing it off the list when it's genuinely needed.
When ECT is genuinely indicated
By the clinical guidelines of NICE and the Royal College of Psychiatrists, ECT is considered for a fairly narrow set of situations:
- Severe depression with a direct threat to life — when someone isn't eating or drinking, and waiting weeks for antidepressants to kick in is simply dangerous.
- Catatonia — a state with immobility, refusal to eat and speak, seen in severe depression, schizophrenia, and certain physical illnesses. ECT often lifts catatonia within a few sessions.
- Severe mania that hasn't responded to medication.
- Treatment-resistant depression — when two or more courses of antidepressants at adequate doses, plus psychotherapy, haven't produced a result.
- Psychotic depression — depression with delusions or hallucinations.
- Severe depression during pregnancy, when antidepressants pose a greater risk to the foetus than the procedure itself.
The shared logic: ECT is a last-line tool that steps forward when either time is critical or standard treatment has already failed.
If the situation is acute and there are thoughts of suicide or self-harm, don't wait and don't try to weigh the options alone — there are helplines that operate around the clock and anonymously.
When ECT isn't the first step
The "not indicated" list is much longer than the "indicated" one. In clinical guidelines, ECT is not considered first-line for:
- mild and moderate depression,
- anxiety disorders without severe depression,
- panic disorder,
- PTSD,
- personality disorders,
- difficult life circumstances without a clinical diagnosis (grief, divorce, burnout).
For all of these, other things work: psychotherapy (especially CBT, interpersonal therapy, schema therapy), antidepressants for moderate and severe depression, and for panic — short techniques like 4-7-8 breathing or 5-4-3-2-1 grounding in the moment, plus therapy over the longer arc.
"A psychologist is better than ECT" isn't a contest. It's a question of which tool fits your specific situation.
What it actually looks like
For the decision to be informed, it helps to know what the procedure looks like from the inside:
- Preparation: assessment, ECG, sometimes MRI. An anaesthetist reviews the risks.
- The session itself: general anaesthesia (about 5–10 minutes), a muscle relaxant, electrodes on the head, a brief pulse. You feel nothing.
- Afterwards: 20–60 minutes of observation; mild disorientation and headache are common but short-lived side effects.
- The course: 6–12 sessions, typically 2–3 times per week. Many people notice improvement by the 3rd–4th session.
- Memory: the most discussed side effect. Most often it's memory for events around the treatment period that's affected. For most people it recovers within weeks to months; for some, fragments don't come back. Modern techniques (right unilateral placement, ultra-brief pulse) noticeably reduce this effect but don't eliminate it.
- After the course: maintenance treatment is usually arranged — antidepressants, psychotherapy, or occasional maintenance ECT sessions — otherwise the chance of relapse is high.
What to ask the doctor if the choice is in front of you
If a doctor is offering ECT — for you or for someone close — it's reasonable to take a pause and ask questions. A good psychiatrist will answer them calmly:
- Why ECT specifically in my situation? What alternatives were considered and why were they set aside?
- Which technique will be used (bilateral / unilateral, pulse duration)?
- How many sessions are planned and how will you track the effect?
- What side effects are possible in my specific case given my age and condition?
- What happens after the course to hold the result?
- What happens if I decline ECT — what are the fallback options?
If you'd like to sort through your emotions and questions calmly before the conversation with the psychiatrist, a psychologist can help — that's not a substitute for the medical decision, but a way to walk into it with a clearer head.
