Electroconvulsive therapy (ECT) shows short-term benefits for schizophrenia, especially when combined with antipsychotics. However, long-term effectiveness and optimal administration methods require further research.

Area of Science:

  • Psychiatry and Neurology
  • Clinical Neuroscience

Background:

  • Electroconvulsive therapy (ECT) is a treatment for psychiatric disorders involving induced seizures via scalp electrodes.
  • The efficacy and impact of ECT on schizophrenia symptoms and functioning remain incompletely understood.

Purpose of the Study:

  • To evaluate the clinical benefits of ECT for individuals with schizophrenia, focusing on global improvement, hospitalization rates, and functional outcomes.
  • To investigate how variations in ECT administration affect treatment results in schizophrenia.

Main Methods:

  • Systematic review and meta-analysis of randomized controlled trials (RCTs) comparing ECT with placebo, sham ECT, non-pharmacological interventions, and antipsychotics.
  • Searches included major databases (MEDLINE, EMBASE, PsycLIT) and the Cochrane Schizophrenia Group Register up to July 2004.

  • Data analysis involved calculating risk ratios (RR), confidence intervals (CI), and weighted mean differences (WMD), with intention-to-treat analysis.

    • Main Results:

    • ECT demonstrated short-term global improvement compared to sham ECT (NNT=6), with no significant difference in dropout rates.
    • ECT showed a trend towards reduced short-term relapses and increased hospital discharge rates versus sham ECT.
    • Antipsychotic medications were favored over ECT alone for improvement, but ECT combined with antipsychotics showed superior outcomes, particularly for rapid symptom reduction.

    Conclusions:

    • ECT, particularly when combined with antipsychotic drugs, may be a valuable option for schizophrenia, especially for rapid symptom control and in cases of poor medication response.
    • While initial benefits are noted, the long-term maintenance of ECT's effects requires further investigation.
    • Despite decades of use, critical questions persist regarding the optimal role and application of ECT in schizophrenia management.
