Electroconvulsive Therapy in Clozapine-resistant Schizophrenia

October 15, 2015 updated by: Niuvanniemi Hospital

Efficacy and Cognitive Effects of Electroconvulsive Therapy in Clozapine-Resistant Schizophrenia

Electroconvulsive therapy (ECT) is one of the oldest neuromodulation treatments still used in psychiatry. Only case reports and open label non-randomized studies have been published of ECT in clozapine-resistant schizophrenia patients. The purpose of this trial is to study the efficacy and cognitive effects of add-on ECT treatment (10-course) in schizophrenia patients taking clozapine.
