Comment on Amplitude Titration Study in Neuropsychopharmacology

 Out on PubMed, from authors in Minnesota, is this commentary:


Advances in precision neuromodulation: electroconvulsive therapy amplitude titration.

Croarkin PE, Opitz A.Neuropsychopharmacology. 2024 Jan 9. doi: 10.1038/s41386-024-01797-3. Online ahead of print.PMID: 38195909


The article is here.

And here.



So here is a commentary about the Abbott et al. article I discussed yesterday on the blog. It nicely summarizes the study, as well as its limitations.
To simplify, standard ECT is too powerful for some patients, so it is helpful to be able to offer less powerful treatments to other patients.
E-field may be a good measure of "strength," or "power," but at present can only be crudely estimated, or require complicated additional investigations for better estimates. Is electrical dosing analogous to milligram dosing with pharmaceuticals? To a certain extent, yes. With drugs, most patients get the same dose in a pill; only when drugs are given IV are they sometimes tailored to the individual by weight. While this may not be optimal or "personalized," it works well for most.
From a slightly different perspective, the strength of ECT is its remarkable strength; many ECT patients are desperately ill and need full strength treatment. It would be great to have both power and optimized tolerability, which is the aim of the described research. Until that goal is achieved, lets remember that efficacy tops (valid) concerns about transient cognitive effects.

Out on PubMed, from investigators in the US, is this study: Ketamine versus  ECT   for Nonpsychotic Treatment-Resistant Major Depression. Anand A, Mathew SJ, Sanacora G, Murrough JW, Goes FS, Altinay M, Aloysi AS, Asghar-Ali AA, Barnett BS, Chang LC, Collins KA, Costi S, Iqbal S, Jha MK, Krishnan K, Malone DA, Nikayin S, Nissen SE, Ostroff RB, Reti IM, Wilkinson ST, Wolski K, Hu B. N Engl J Med. 2023 May 24. doi: 10.1056/NEJMoa2302399. Online ahead of print. PMID:  37224232 The abstract is copied below: Background:  Electroconvulsive therapy (ECT) and subanesthetic intravenous ketamine are both currently used for treatment-resistant major depression, but the comparative effectiveness of the two treatments remains uncertain. Methods:  We conducted an open-label, randomized, noninferiority trial involving patients referred to ECT clinics for treatment-resistant major depression . Patients with treatment-resistant major depression without psychosis were recruited and assigned in a 1:1 rat

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

Image
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

ECT For Children at a University Hospital: New Study in JECT

Image
 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.
