Maintenance Electroconvulsive Therapy (ECT) Versus Aripiprazole in Clozapine-resistant Schizophrenia

Summary

The pharmacological treatment options in schizophrenia developing resistance to clozapine are limited. Few studies have found ECT as beneficial in TRS, including CRS. However, literature on the role of M-ECT in maintaining the therapeutic gains of acute ECT in CRS is lacking. The objective of the study is to compare the efficacy of M-ECT vs aripiprazole as an add-on to ongoing clozapine on the severity of symptom dimensions, cerebral perfusion, global functioning and cognitions in patients with CRS.
