This paper presents the history of ECT in the treatment of schizophrenia and its evolution, from it's discovery in the 20th century, which is an example of empiricism with a sequence of "" therapies. Following this discovery, the use ECT in schizophrenia has been in expansion during several decades, in a context of lack of efficacy of the treatment in schizophrenia. Then, after World War II and the derivative use of ECT in Germany, the use of ECT has decline during several decades. However, in the last decades, the use of ECT in schizophrenia has reemerged. Indeed, among patients in schizophrenia, rates of resistance to treatment have always been and still are high. In 2017, the concept of "" was defined when clozapine was tried and failed; and ECT, that had been long since abandoned in the treatment of schizophrenia until recent renewed interest, has emerged especially concerning the add-on of ECT to clozapine.
