Background: Electroconvulsive therapy (ECT) is a highly effective treatment for schizophrenia and mood disorders; however, most evidence is derived from the adult population, with less evidence in adolescents. We sought to determine the use of ECT in adolescents in the Institute of Mental Health (IMH) and evaluate the treatment outcome.
Methods: We conducted a retrospective naturalistic analysis of ECT registry data of patients aged from 10 to 19 years from March 2017 to March 2023. Descriptive analysis was used to analyze the demographics and clinical characteristics. Paired t tests were used to compare the change in clinical outcome scores, including the Brief Psychiatric Rating Scale (BPRS), Montgomery-Asberg Depression Rating Scale (MADRS), Clinical Global Impressions Scale - Severity (CGI-S), and Montreal Cognitive Assessment (MoCA) before and after 2 weeks of ECT treatment.
Results: Fifty-five patients were included for analysis. There was a significant improvement in BPRS (P < 0.001), MADRS (P = 0.005), and CGI-S (P < 0.001), and the average CGI-I score was 2.275 (SD, 0.81), which is equivalent to "much improved" after 6 sessions of treatment. Of all patients, 48.5% showed significant clinical improvement. There was no significant change in MoCA scores (P = 0.218).
Conclusions: Our preliminary findings show that ECT is a safe, rapid, and effective treatment for psychotic and mood disorders in adolescents. Further studies with a larger sample size and specific subgroup analysis are needed to establish the effectiveness of ECT and identify predictors of response in this population.
