Shock therapy, or electroconvulsive therapy (ECT), is a medical procedure used to treat severe depression and other mental health conditions. It involves administering electrical currents to induce controlled seizures in the brain. ECT has shown efficacy in relieving symptoms of depression, but it also has potential side effects such as temporary confusion and memory loss. It has been controversial due to historical misuse, but strict ethical guidelines now ensure responsible use. Patient experiences vary, and alternative treatments are available.
