Electroconvulsive therapy involves inducing a seizure through electrodes attached to the temples by passing electrical current. It is increasingly administered on an outpatient basis to seniors for depression. A muscle relaxant is given to minimize seizure activity and prevent bone damage. A typical course is 6-12 treatments over 2-3 weeks, with maintenance therapy monthly to prevent relapse. It is used for treatment-resistant cases of major depression, bipolar disorder, and schizophrenia, as well as in emergency situations involving suicide risk. Potential side effects include confusion, memory loss, and fractures.
