Could a treatment meant to help actually be causing more harm than good? Electroconvulsive therapy (ECT), often used as a last resort for severe depression, may have a far darker side than we previously thought. A new study is raising serious questions about the safety and long-term effects of this controversial procedure, suggesting it might be time to hit pause until we know more.
For years, we've known that ECT, which involves sending electrical currents through the brain to induce seizures, can lead to memory loss. But this new research reveals a laundry list of additional potential side effects that are frankly alarming.
The study, published in the International Journal of Mental Health, surveyed 747 ECT patients and 201 of their loved ones. Now, it's important to note that this type of survey can only suggest possibilities, not prove them definitively. But given how difficult it is to study ECT, these findings could be crucial. The study highlights 25 concerning side effects beyond memory loss, including:
- Cardiovascular problems: Nearly a quarter of participants (22.9%) reported heart issues like arrhythmia after ECT.
- Recurring headaches: A staggering 53.9% experienced persistent headaches.
- Emotional blunting: More than three-quarters (76.4%) reported feeling emotionally numb or detached.
And this is the part most people miss: some side effects are subtle but devastating, stemming from memory loss and affecting relationships, navigation skills, and even vocabulary.
Professor John Read, the study's author at the University of East London, doesn't mince words. "Given that we still don’t know if ECT is more effective than placebo, these startling new findings make it even more urgent that it be suspended pending a thorough investigation into both safety and efficacy." He even goes so far as to say that if ECT were a new treatment seeking approval today, it wouldn't stand a chance with regulatory bodies like the MHRA in the UK or the FDA in the USA.
Sue Cunliffe's story is a stark example of the potential consequences. After receiving ECT for severe depression in 2004, she describes her life as "completely wrecked." She's been left with slurred speech, shaking hands, impaired balance, and struggles with basic tasks like recognizing faces, counting money, and reading. Before ECT, she was active and creative; now, she battles constant brain fog and fatigue, preventing her from working as a doctor.
ECT is typically administered to around 2,500 people in the UK each year, primarily for treatment-resistant depression, but also for conditions like schizophrenia, bipolar disorder, and catatonia. It's often seen as a last resort, especially when other treatments have failed. The process involves inducing seizures under general anesthesia, usually over a course of 6 to 12 treatments.
But here's where it gets controversial... ECT remains a deeply divisive topic within the mental health community.
While some professionals swear by its effectiveness, others are deeply skeptical. Professor Tania Gergel, director of research at Bipolar UK, argues that there's "no evidence to substantiate claims that modern ECT carries any major risk to physical health or that it causes long-term brain damage and permanent deterioration of cognitive functioning." She acknowledges that memory loss can occur but emphasizes that ECT can be a vital tool for managing acute symptoms and enabling people to engage with other therapies. Professor Gergel herself relies on ECT to manage her treatment-resistant bipolar disorder.
Professor George Kirov from Cardiff University echoes this sentiment, calling ECT "highly effective" and "life-changing" for people with severe depression, with around 60% experiencing symptom improvement. He believes that stigma has led to its underutilization in the UK, while it's more common in other northern European countries.
However, Lucy Johnstone, a clinical psychologist and member of the UK ECT Improving Standards Campaign Group, raises a different concern. She points out that many people are unaware that ECT is still used and that it's disproportionately given to older women, with a significant number receiving it against their will. Johnstone also suggests that a significant proportion of ECT patients are victims of domestic abuse, an issue that may not be adequately addressed by mental health professionals.
The National Institute for Health and Care Excellence (NICE) guidelines state that ECT should only be considered for severe, life-threatening depression when a rapid response is needed, when it aligns with the patient's past positive experience, or when other treatments have failed. NICE also emphasizes the importance of informing patients about the risks and benefits and ensuring that clinics are properly accredited.
Ultimately, the question remains: Is ECT truly a safe and effective treatment, or are we potentially causing more harm than good? This new research demands a serious reevaluation of ECT's risks and benefits.
