Electroconvulsive therapy (ECT) is a medical treatment used primarily for severe depression and certain other mental health conditions. It involves sending small electrical currents through the brain to induce a brief seizure. This process is believed to help reset brain chemistry and improve mood. ECT is typically administered under anesthesia and is closely monitored by healthcare professionals. The treatment usually requires multiple sessions over a few weeks. While ECT can be effective for many patients, it may also have side effects, such as temporary memory loss. It is often considered when other treatments, like medication or therapy, have not provided sufficient relief.
