Background: A significant proportion of patients with a depressive disorder show resistance to pharmacological and psychotherapeutic antidepressant treatments. Electroconvulsive therapy (ECT) is still one of the most effective treatment methods, especially in the acute phase. In everyday clinical practice, this usually accompanies pharmacological treatment. It has been shown that pharmacological treatment following acute ECT treatment reduces the rate of relapses. However, the effect of various antidepressants (ADs) and antipsychotics (APs) on the effect during the course of ECT has rarely been investigated.

Methods: In this retrospective chart review study, the data of 104 depressive patients treated with ECT were examined. We analyzed the influence of concomitant administration of AD and AP or no psychotropic medication on the effect of ECT using the Montgomery-Åsberg Depression Rating Scale (MADRS). We further analyzed the influence of the ADs Bupropion, Venlafaxine, and Sertraline or no AD and the influence of augmentation with Aripiprazole or Quetiapine or Olanzapine.

Results/discussion: Psychotropic medication did not have an impact on antidepressant efficacy of ECT as measured with the MADRS scores. In addition, the comparison between the antidepressant or antipsychotic medications themselves did not show any significant difference. However, we found a significantly different seizure duration depending on the antidepressant substance that patients received during ECT (p = .008). ECT treatment itself led to a highly significant reduction of 13.3 points in the MADRS (p <.001).

Conclusion: Taken together, our study underlines that concomitant psychotropic medication while doing electroconvulsive therapy does not bare the risk of prolonged seizure duration or does it reduce the effectiveness of ECT. To the best of our knowledge, this study is the first to examine the effect of treatment with antidepressants in combination with antipsychotics while doing ECT. In light of our results, this combination therapy is safe and effective. Bearing in mind the delay in onset of antidepressant action of medication and the importance of antidepressant medication for relapse prevention, this study further supports the recommendation that psychotropic medication should be given in adjunction to ECT.

And from the text:










Here's a good retrospective dataset showing little effect of concomitant antidepressant and/or antipsychotic medication on ECT outcome or seizure duration. One interesting tidbit is the slight decrease of seizure duration, rather than the expected increase, with bupropion, further supporting safe concomitant use.
Kudos to these authors for contributing their useful retrospective dataset to the ECT evidence base.

RUL ECT vs Low Amplitude Seizure Therapy (LAP-ST)

Out on PubMed, from the team in Augusta, Georgia, is this study: Double-Blinded Randomized Pilot Clinical Trial Comparing Cognitive Side Effects of Standard Ultra-Brief Right Unilateral ECT to 0.5 A Low Amplitude Seizure Therapy (LAP-ST). Youssef NA, McCall WV, Ravilla D, McCloud L, Rosenquist PB. Brain Sci. 2020 Dec 13;10(12):E979. doi: 10.3390/brainsci10120979. PMID:  33322138 The pdf is here . And from the Introduction : In theory, LAP-ST can be helpful because of the direct effect of lower electric current, but the principal reason is that LAP-ST has a more focal electric field (EF) [ 34 , 35 ]. The current amplitude is the primary factor that drives the EF into brain regions located deeper in the brain and is responsible for cognition and memory such as the hippocampus and temporal lobe [ 33 , 35 ]. This extra focality of the EF can minimize or avoid high EF stimulation to the deeper hippocampal and temporal lobe regions [ 33 , 35 ]. Minimization of deeper stimulation by using LAP

 Out on PubMed, from authors at Vanderbilt and Mass General,, is this article: Use of   ECT   for Children With and Without Catatonia: A Single-Site Retrospective Analysis. Smith JR, Baldwin I, Termini KA, McGonigle T, Vandekar S, Luccarelli J. J ECT. 2024 Jan 25. doi: 10.1097/YCT.0000000000000993. Online ahead of print. PMID:  38265759 The abstract is copied below: Objectives: The objective study was to investigate the safety and efficacy of electroconvulsive therapy (ECT) in a retrospective cohort of pediatric patients. Methods: A single-site retrospective analysis was conducted of patients aged younger than 18 years who received ECT in a private university hospital from January 28, 2012 to April 8, 2023. Treatment efficacy and adverse events were determined retrospectively through review of the medical record. Results: A total of 36 pediatric patients met the inclusion criteria. Catatonia was the most common presenting indication for ECT, followed by psychosis and suicidal ideation.
