Study Notes
Electroconvulsive Therapy (ECT) and Psychosis
- ECT augmentation of antipsychotic medication can be beneficial for persistent positive symptoms in schizophrenia.
- ECT is particularly helpful for medication-resistant schizophrenia.
- ECT, in comparison to placebo or sham ECT, has been shown to improve symptoms and reduce relapses in the short term.
- Combining ECT with continuing antipsychotic medication is a valid treatment option for schizophrenia, especially when rapid improvement is desired and medication alone hasn't been effective.
- A study of over 2,000 patients with schizophrenia showed that those receiving ECT had a lower rate of psychiatric hospitalization compared to controls.
- The effectiveness of ECT was stronger among those treated with clozapine or taking higher doses of antipsychotics.
Treatment-Refractory Schizophrenia (TRS)
- ECT augmentation for TRS has demonstrated a positive effect on medium-term clinical response, but more high-quality evidence is needed.
- ECT coupled with antipsychotic medication has resulted in significant symptom reduction in TRS.
- ECT combined with non-clozapine antipsychotics is superior to antipsychotic monotherapy in terms of symptom improvement, response, and remission rate.
- ECT augmentation of clozapine may be at least as effective as other antipsychotic augmentations.
ECT Augmentation of Clozapine Treatment
- A retrospective study found that ECT augmentation of clozapine resulted in improvement in about three-quarters of patients.
- ECT augmentation of clozapine led to a significant reduction of psychotic symptoms in half of patients, whereas none improved with clozapine alone.
Systematic Review and Meta-Analysis
- More robust controlled studies are needed to fully assess the efficacy of ECT augmentation of clozapine.
Adverse Effects of ECT Augmentation
- ECT augmentation is generally well-tolerated.
- Potential adverse effects include transient amnesia, headaches, nausea, increased blood pressure, and prolonged seizures (uncommon).
- Cognitive side effects are typically mild and temporary.
Summary
- ECT augmentation of clozapine therapy shows promise, particularly in treating TRS.
- More controlled trials are essential to fully evaluate the long-term risks and benefits of this treatment strategy.
