Electroconvulsive Therapy in First-Episode Schizophrenia

Abstract

Knowledge about the efficacy of electroconvulsive therapy (ECT) on schizophrenia comes from chronic patients and little known on young, first-episode patients. The aim of this study is to evaluate short-term and long-term efficacy of ECT in patients with first-episode schizophrenia. In the first phase of the study, 90 hospitalized, first-episode patients with schizophrenia were enrolled; psychopathology was evaluated with Brief Psychiatric Research Scale (BPRS), Scale for the Assessment of Positive Symptoms (SAPS), and Scale for the Assessment of Negative Symptoms (SANS) on admission and discharge. Antipsychotics were first-line treatment for most of the patients, but medication for nonrespondent catatonic patients and patients who had violent behaviors were treated with ECT. The patients who met the remission criteria were intended to a 1-year follow-up after discharge. BPRS, SAPS, and SANS were monthly recorded during the follow-up. Differences in clinical characteristics, relapse, and rehospitalization rates were analyzed in patients with or without ECT treatment. Thirteen patients were treated with ECT. They were low educated and were more likely nonparanoid subtypes (catatonic, disorganized). The ECT group had higher BPRS scores on admission and their hospitalization period was longer than the antipsychotic group. On the contrary, BPRS and SAPS scores of the ECT group were lower at discharge. The ECT group presented shorter follow-up duration than the antipsychotic group during the follow-up period. In conclusion, the efficacy of ECT was very satisfactory in acute term in first-episode schizophrenia, but the same efficacy was not continuous during the 1-year follow-up.
