![]() ![]() ![]() ![]() Health ![]() Electro-convulsive Therapy ![]() ECT is a treatment for severe depression ![]() Once a commonly used - and controversial - treatment for a variety of mental problems, ECT still bears a stigma despite advances which have made it far safer and more effective. ECT involves placing electrodes on the temples, on one or both sides of the patient's head, and delivering a small electrical current. The aim is to produce a seizure lasting up to a minute, after which the brain activity should return to normal. Patients may have more than one treatment a week, and perhaps more than a dozen treatments in total. Used to treat depression Modern ECT is used primarily in the treatment of severe depression, and psychiatrists say it has proved the most effective treatment in many cases. It is also used in some cases of schizophrenia and mania. But mental health campaigners say that, although it may work in the short term, it is unclear what its long-term effects are. Charity Mind says it is often used against people's will and it wants to see a ban on this. The first official figures for ECT to be released for eight years show 2,800 people were given the treatment in the first three months of 1999. Most were women, many aged over 65, and a quarter were detained under the Mental Health Act. Of the latter, 59% received ECT against their will. The death rate from ECT used to be quoted as 1 for every 1,000 patients, but with smaller amounts of electric current used in modern treatments, accompanied by more safety techniques, this has been reduced to as little as 4.5 in 100,000 patients. Patients are treated with short-acting anaesthetics, muscle relaxants and breathe pure oxygen. However, despite the fall in death rates, there are still side effects to the treatment. The most common are headache, stiffness, confusion and temporary memory loss on awaking from the treatment - some of these can be reduced by placing electrodes only on one side of the head. Memory loss can be permanent in a few cases, and the spasms associated with the seizure can cause fractured vertebrae and tooth damage. Patients can also experience numbness in the fingers and toes. No evidence for brain cell loss A common argument against ECT is that it destroys brain cells, with experiments conducted on animals in the 1940s often cited as evidence. However, modern studies have yet to reproduce these findings in the human brain. Some activists, however, still campaign against the widespread use of ECT in psychiatry, quoting those cases which have resulted in long-term damage or even death, whether because of the built-in chance of problems, or through errors by doctors. Experts say that given the correct staff training, and when used for the right clinical conditions, ECT can "dramatically" benefit the patient. But the Royal College of Psychiatrists admitted recently that the treatment is often administered by untrained, unsupervised junior doctors. ![]() |
