Electroconvulsive Therapy (ECT)
ECT (also known as shock therapy) is a type of biomedical therapy in which a brief electric current is sent through the brain of a patient in order to produce a chemical change. This treatment, although not practiced commonly, is most often used to treat severely depressed people, and has been shown to work quite effectively. ECT fell out of favor and was perceived as cruel and inhuman, but in recent years has regained some popularity.
