Study finds Electroconvulsive therapy (ECT) is safe

Electroconvulsive therapy (ECT) is a highly effective treatment for severe depression and other mental disorders, but the procedure is feared by many. A recent study headed by researchers from Aarhus University in Denmark documents that this fear is unfounded.

There is no shortage of frightening images of electroconvulsive therapy (ECT) in movies – most notably in “One flew Over the Cuckoo’s Nest”, in which the main character Randle McMurphy (Jack Nicholson) is given electroconvulsive therapy (ECT) at a psychiatric hospital in Oregon, USA in the 1970s.

It has turned out to be difficult to move on from the associations between ECT and pain, the exercise of power and danger. Even though “One flew Over the Cuckoo’s Nest” is 43 years old, the negative image of ECT remains intact for many people. This is emphasised by the fact that every fifth respondent to a British survey expressed a fear of dying from ECT. This is an unfortunate statistic according to Associate Professor Søren D. Østergaard from Aarhus University Hospital – Risskov, which is part of the Department of Clinical Medicine at Aarhus University in Denmark.

“In the psychiatric field we have had a clear impression that the fear of dying due to ECT was unfounded, but we have lacked a large-scale study on the topic. We have therefore conducted a systematic review of the literature that contains information about so-called ECT-related deaths, that is deaths where ECT represents the most likely cause of death,” explains Søren D. Østergaard.

Søren D. Østergaard is senior author of the article “The mortality rate of Electroconvulsive Therapy (ECT): A systematic review and pooled analysis”, which was recently published in the journal Acta Psychiatrica Scandinavica. The most significant result in the article is that only one ECT-related death has been reported for the 414.747 ECT treatments that are registered in studies published after 2001.

“The risk is very small and even many elderly patients with comorbid medical illnesses can be safely treated with ECT,” says Søren D. Østergaard.

The systematic review covered 15 studies with data from 32 countries published in the period from 1976 to 2014. For this entire period, the ECT-related mortality was estimated at 2.1 per 100,000 treatments. By comparison, the number of death caused by surgery under general anaesthesia was recently estimated at 3.4 per 100,000 surgeries.

“The idea of an electric current running through the head is unpleasant, and some patients find it difficult to forget the frightening portrayals of ECT from movies. But these have little resemblance with reality,” says Søren D. Østergaard.

“One Flew Over the Cuckoo’s Nest is a great movie, but it has been detrimental to psychiatry, because ECT was shown as being a form of punishment. That could hardly be farther from reality,” explains Søren D. Østergaard.

ECT is still portrayed very negatively in movies. This was the main conclusion in the review “Based on a true story? The Portrayal of ECT in International Movies” from 2016. For instance, ECT is often portrayed as a treatment that is given without anaesthesia, despite the fact that ECT treatment is only carried out under general anaesthesia in developed countries and with the use of muscle relaxants, so that the convulsions are minimal.

“These frightening images cause great harm because in addition to being a very safe procedure, ECT is a highly effective treatment for many patients suffering from severe psychosis, mania or depression,” says Søren D. Østergaard. He describes how extremely tormented patients can – during the course of just 2-3 treatments over a week – go from being in the deepest depression, being unable to take care of themselves, to gradually become their old selves again. Most often 8-12 treatments are required before a patient gets well.

“Typically, you can see the improvement caused by ECT in the patient’s eyes, facial expression and posture already before talking to him or her about the mood. Prior to the treatment these individuals are often not able to eat or take a shower because they are so extremely ill, and then a couple of weeks later they sit in front of you with their chin up and a completely different intensity in their eyes. That leaves a great positive impression on you,” says Søren D. Østergaard.

As with most forms of treatments, ECT has side effects. Some of the most common are headache and nausea, but memory impairment is probably the most feared side effect of ECT.

“Memory impairment is a side effect for some patients, but for the majority the impairment is temporary. In addition, it is essential to weigh the side effects against the highly beneficial effects of ECT on the mental disorder being treated. Patients receiving ECT are often so ill that they do not want to live anymore. For these individuals, ECT can be life saving,” says Søren D. Østergaard.

“Close to 800,000 people die from suicide every year. I strongly believe that many of these suicides could have been prevented had these individuals received ECT in due time,” says Søren D. Østergaard.

  1. I developed dementia fro ECT in my 20s and my doctors refused to recognize my severe disability for almost a decade. I very nearly killed myself BECAUSE of my injury and denial of help and recognition. This is the standard response doctors have to people disabled by ECT. Thanks to articles like yours, the majority of non medical people think ECT is safe and ethical and those of us injured by it are crazy or lying and those desperately depressed are encouraged to have ECT.

  2. SEVERE SEVERE memory loss after ECT is real. It has been 15 months and I’m still not right cognition wise. The main point of this article is true ECT is relatively “safe” as far as immediate death, bodily injury, or physical pain is concerned. This does not mean that it is free from SERIOUS risks in terms of cognitive (definitely short term and sometimes long term/ indefinite) side effects.

  3. I was given ECT in 1971 after being sectioned, my ‘mental illness’ being described as ‘catatonic depression’ (a meaningless diagnosis) when my main problem was grief – and I was given ECT as a punishment, for not cooperating with the psychiatrist.
    Since ECT, for the last more than 45 years, on an often daily at least weekly basis, I have been plagued by the whole host of ECT after-effects recorded in survey after survey of ECT survivors – memory loss (I had to relearn the numbers, times table, the names of my parents and siblings etc etc), sudden mood swings, perpetual suicidal thoughts (not experienced before ECT), loss of identity (who I am), social isolation, nervous tics, unaccountable weeping fits, fear of travel (although I did VSO in my youth) etc etc
    I’d suggest that anyone about to be given ECT, and/or their family, friend, advocate, go to ECT survival groups and read the practical testimony of survivors (including those given ‘modern’ ECT very recently) as well as reading theoretical articles like the one above – otherwise ‘informed consent’ is a joke, and they’ll realise too late that ECT is an experiment, just as it was when used by the Nazis on concentration camp victims.

  4. You are a monster of a human being.
    6 years later.
    My brain is not as it was.
    You have basically given me a lobotomy.
    I will end my life due to this and the suffering it causes.

    You are making people suffer long term.
    From the depth of my soul just DIE and listen to what people are saying about what they experience long term after ect.

    Looking into someone’s eyes straight after is not Science you f***head.
