Electroconvulsive Therapy: Not What You Think
Mental illness is very common. One in five Australians aged 16-85 experience a mental illness every year. The most common causes are depression, anxiety and substance abuse or a combination of all three.
One successful treatment that’s available for people is electroconvulsive therapy, or ECT. This therapy is reserved for people with severe depressive disorders who are very unwell and have not responded to other treatments. And it’s also widely misunderstood by the general public, clouded in myths.
When a patient has an ECT they are lightly anaesthetised. The patient is asleep during the electrical stimulation. This stimulation does induce a seizure which lasts for 20-30 seconds and then the patient spontaneously wakes up. A patient receives one electrical stimulation per session.
Treatment plans vary patient to patient and depend on their particular circumstances. But typically a patient may receive eight to nine treatments with an average of three per week. There is no limit to the number of ECT treatments a patient can have.
There are a number of myths around ECT. The facts are a long way from many peoples’ perceptions.
- The patient isn’t awake during treatment
- The treatment is not painful as the patient is anaesthetised and they also take a muscle relaxant prior
- No medically recognised links to dementia
- There are no changes to a patients personality following treatment
- ECT does not cause any long term memory loss
Dr Wong confirmed “That while there may be some patchy short term memory loss following treatment, it’s not long standing. In fact, often cognitive thinking can improve as depression deteriorates a patients thinking capabilities. The other good news is there is an 80-90% success rate and psychiatrists believe it is the most effective treatment for severe depression.”
ECT can only be administered by a specialised and trained psychiatrist. Epworth HealthCare has a dedicated ECT team at their mental health clinic in Camberwell.
While severe depression requires clinical treatment, Dr Wong believes there are some common practices that everyone can use to maintain positive mental health:
- Maintain a good diet
- Get regular exercise
- Conduct basic stress management
- Maintain strong, supportive and healthy relationships with friends and family
- Ask people for help

Getting an x-ray is not the frightening concept it once might have been. We know so much about all types of scans and the potential hazards and how to avoid them, and technology is rapidly advancing. Some hospitals even boast an EOS now, which allows them to complete scans with 6-9 times less radiation than typical x-rays.
It’s rarely contested that being around nature has benefits for your health. It ensures you’re spending more time outdoors, gives you a sense of connectedness with the world, and has been found to lower stress and reduce the symptoms of depression and anxiety. The best news is that even in the city there are many places to get in touch with nature. Here are five of them:
