ELECTROCONVULSIVE THERAPY AS A SECOND-LINE TREATMENT FOR BIPOLAR MANIA

Introduction and Objective: Bipolar disorder affects approximately 2-4% of the global population, with acute mania representing a significant clinical challenge. While pharmacological interventions remain first-line treatments, 20-30% of patients experience inadequate response or intolerable side effects. This review evaluates the efficacy, safety, and clinical implementation of electroconvulsive therapy (ECT) as a second-line intervention for treatment-resistant bipolar mania. Material and Methods: A comprehensive analysis of contemporary literature was conducted, examining controlled trials, meta-analyses, systematic reviews, and clinical guidelines published between 1988 and 2024. The review focused on clinical response rates, comparative efficacy studies, adverse effect profiles, technical parameters, and integration with pharmacotherapy. Results: Evidence consistently demonstrates high efficacy rates (80-90%) for ECT in treatment-resistant mania, with rapid symptom resolution often occurring within the first week of treatment. Modern ECT techniques have substantially mitigated historical concerns regarding cognitive side effects. Bilateral electrode placement traditionally yields faster response in acute mania, though high-dose right unilateral placement may offer comparable efficacy with reduced cognitive impact. Integration with appropriate pharmacotherapy enhances long-term outcomes. Special populations, including pregnant women, elderly patients, and those with medical comorbidities, may particularly benefit from ECT when properly administered with population-specific modifications. Conclusions: ECT represents an effective, relatively safe, and rapid-acting intervention for treatment-resistant bipolar mania that should be considered earlier in treatment algorithms rather than as a last resort. Individualized approaches to electrode placement, stimulus dosing, and maintenance strategies optimize outcomes while minimizing adverse effects. Future research directions include parameter optimization, identification of predictive biomarkers, and development of cognitive remediation strategies.
