|TREATMENT| Why should anyone ever have thought that ECT was a sensible way to treat a mental disorder? ECT consists of passing an electrical current through the brain to produce an epileptic fit – hence the name, electro-convulsive. On the face of it, this sounds bizarre. The idea developed from the observation that, in the days before there was any kind of effective medication, some people with depression or schizophrenia, and who also had epilepsy, seemed to feel better after having a fit. Research suggests that the effect is due to the fit rather than the electrical current. Many doctors believe that severe depression is caused by problems with certain brain chemicals. It is thought that ECT causes the release of these chemicals and, probably more importantly, makes the chemicals more likely to work and so help recovery.
