Electroconvulsive therapy (ECT) is a procedure, done under general anesthesia, in which small electric currents are passed through the brain, intentionally triggering a brief seizure. ECT seems to cause changes in brain chemistry that can quickly reverse symptoms of certain mental health conditions. ECT often works when other treatments are unsuccessful and when the full course of treatment is completed, but it may not work for everyone.

What are the side effects of ECT?
Here is a list of the most common side effects: 1 Disorientation (usually lasts between a few minutes to a few hours after an ECT session) 2 Aches, fatigue and nausea are other short-term side effects from ECT 3 Memory loss: Memory loss is the biggest issue with ECT and a common side effect. Some people lose memories of events that took place months before they had ECT treatment and some are left with permanent gaps in memory. Most depressed patients say that the ECT treatment was worth losing a few memories over, but others report that they have lost precious memories, for example, the memory of a family trip or even their wedding day. The memory loss is usually worse shortly after the ECT treatment and then gradually improves with time. A minority of ECT patients report memory problems that remain for months or years. Unfortunately, there is currently no way to tell who will be affected by memory problems, which means that memory loss is a risk for everyone who decides to go through ECT treatment.#N#Worth noting is that concentration difficulties and memory problems are a common symptom of severe depression. In some cases where ECT treatment has been successful and these symptoms have disappeared, patients have actually experienced that ECT improved their memory functions. 4 Difficulty in forming new memories: Another side effect of ECT is having difficulties creating new memories. This side effect is temporary and usually disappears a few weeks after ECT treatment.
