The Impact of Electroconvulsive Therapy on Negative Symptoms in Schizophrenia and Their Association with Clinical Outcomes

Evaluating the use of electroconvulsive therapy in low-middle income countries: A narrative review

BACKGROUND

Electroconvulsive therapy (ECT) is a well-accepted intervention for treatment-resistant, serious mental illnesses. Its acceptability, efficacy, and tolerability are well documented in high-income settings, but less so in lower- and middle-income countries (LMICs). This report is a narrative review of ECT practice in the latter setting.

METHODS

A literature search was conducted using Medline and PubMed. Initial results yielded 81 publications in English. Following the screening, 19 papers were included to evaluate the information on ECT practice and perceptions.

RESULTS

Reports from LMICs on efficacy, tolerability, and perceptions of ECT were relatively sparse. In general, they confirm its use mostly for treatment-resistant major mental illnesses (i.e., depression, schizophrenia, bipolar disorder). Both modified and unmodified forms of ECT are used and considered equally effective, although the former is better tolerated. Use of unmodified ECT remains significant in LMICs due to its low cost and limited resource requirements. In general, there is satisfaction with ECT and its outcomes. The education of patients and families, content process, and research have been noted as areas to improve.

CONCLUSIONS

ECT is perceived as an effective intervention in LMICs, but use of unmodified ECT remains controversial. There is a need for the development and use of global guidelines to improve clinician training, knowledge sharing with patients and their families, and outcome research.
