Electroconvulsive therapy of endogenous depression

Abstract

Most patients with endogenous depression who receive electroconvulsive treatment (E.C.T.) recover completely or improve considerably. However, it is evident that the effect of E.C.T. varies in different individuals. In some cases more treatments are necessary than in others and sometimes the final result is unsatisfactory even after a great number of treatments. Many attempts have been made to explain these variations.
