It sounds like something out of an old psychiatric hospital, yet it’s still being used today. Electroconvulsive therapy, or ECT, remains one of the most debated treatments in modern psychiatry, as as stated by Cambridge University. Some see it as lifesaving, while others as outdated and dangerous.
Despite the stigma, psychiatrists continue to recommend it for certain patients, especially when other treatments fail. Understanding why it’s still on the table means looking at what the procedure actually does, why it works for some, and why it sparks so much concern. Let’s go into more detail.
What is electroconvulsive therapy
Electroconvulsive therapy involves passing a controlled electric current through the brain to trigger a brief seizure. Patients are under general anesthesia, and muscle relaxants are used to minimize movement. Treatments are usually given in a hospital setting, often two or three times a week over several weeks.
ECT has been around since the 1930s, and while its methods have been refined, the core principle hasn’t changed. It’s most often used for severe depression, treatment-resistant bipolar disorder, and acute suicidal ideation. Some psychiatrists also use it for catatonia and certain cases of schizophrenia.
The procedure is controversial because of its history and its potential side effects. In the mid-20th century, ECT was often performed without anesthesia, leading to frightening images in popular culture. Even now, patients can experience memory loss, confusion, and cognitive issues after treatment. There are also risks linked to anesthesia, as well as cardiovascular strain during the seizure.
Why psychiatrists may still recommend this treatment
The main reason ECT remains in use is its effectiveness. For those with severe depression who have not responded to medications like SSRIs or SNRIs, ECT can bring rapid relief. Studies show that response rates can be higher than with antidepressants alone, sometimes offering improvement in weeks rather than months. This speed can save the lives of patients at immediate risk of suicide.
Psychiatrists also weigh its benefits against the risks of untreated illness. Severe depression or catatonia can lead to malnutrition, self-harm, or medical complications. For some, the potential for short-term memory problems may be less dangerous than the consequences of an ongoing psychiatric crisis.
That said, many clinicians remain cautious. The British Journal of Psychiatry Advances notes ongoing debates about consent, long-term outcomes, and the ethical dimension of using a treatment that carries such stigma. Critics argue that the risks to cognition are underreported, and that more investment should go into alternatives like transcranial magnetic stimulation (TMS) or advanced pharmacotherapy.
ECT is rarely a first-line treatment. Most psychiatrists will only suggest it after several courses of medication and psychotherapy have failed, or when a patient’s condition is so severe that waiting for other treatments to work is unsafe. It’s often presented as an option of last resort, not a default pathway.
In the end, ECT’s place in psychiatry reflects the complexity of treating mental illness. It highlights the tension between clinical evidence, patient experience, and public perception. For some, it represents hope when nothing else works. For others, it remains a symbol of psychiatry’s more controversial past.
