Aside from the recognized indications, ECT was found to be of decisive help in conversion depressions, a syndrome in which somatic, chiefly visceral autonomic features mask the phasic depressive core. Similarly favorable responses were achieved in pseudoneurotic depressive equivalents, conditions that possess the same phasic depressive core as the conversion depressions, whereas the outward symptoms may mimic anxiety states, compulsive-obsessive or neurasthenic syndromes. In anorexia nervosa, ECT breaks up the conditioned behavior pattern and facilitates psychotherapy. Schizoids with superimposed disabling symptomatology of qualitatively neurotic nature, but quantitatively psychotic degree, showed the most gratifying responses inasmuch as the disabling behavior patterns were broken up by ECT. Improvement of anxiety also was observed. Cases of true compulsive-obsessive neurosis never responded. In narcotic addiction, ECT is a highly valuable tool as far as management of the withdrawal period is concerned. The fact that results were obtained in vastly different conditions by the same standard method creates hesitation as to recent tendencies to assign different modes of electro-therapy to different diagnostic categories.Abstract Teaser
