Introduction: In spite of recent advances in schizophrenia treatment, 30% of patients still do not respond properly to antipsychotic therapy. These patients are considered treatment-resistant or refractory, and the best choice for them is clozapine. However, even supported by the literature as the best known antipsychotic in terms of efficacy and rates of response, a considerable number of patients will still not respond to this treatment, remaining symptomatic and dysfunctional. These patients are classified as super-refractory (clozapine-resistent). In these cases, augmenting strategies are necessary, and some have been in use: typical and atypical antipsychotics, mood stabilizers, antidepressants and electroconvulsive therapy (ECT). Some studies have favored ECT, but no definitive conclusion has been drawn.
