Abstract
Electroconvulsive therapy (ECT) is a safe and effective treatment for catatonia with high response rates. Although empirical data suggest that tolerability and efficacy are at least as good as in adults, ECT treatment of children, adolescents, and geriatric patients seems to pose a specific challenge for many practitioners. This article intends to explore and discuss reasons hindering the use of ECT in these patient groups, give an overview on the use of ECT to treat catatonia and provide practical advice on ECT in children, adolescents, and geriatric patients for the treatment of catatonia. Classification of catatonia as a subform of schizophrenia and a diagnostic overlap with other common conditions in children, adolescents, and geriatric patients might lead to underdiagnosis of catatonia. Concerns about the mechanism of action and about a lack of controlled studies as well as general concerns about the use of ECT in children and adolescents might lead to underutilization of ECT. However, studies of ECT to treat catatonia in children, adolescents, and geriatric patients consistently show its safety and effectiveness. Administration of ECT needs to consider some specific characteristics of children, adolescents, and geriatric patients. In conclusion, ECT is a safe and highly effective treatment for catatonia across the lifespan. Existing evidence does not warrant restrictions of its use in certain age groups.

Abstract
OBJECTIVES Decisions about psychotropic medication administration before electroconvulsive therapy (ECT) are central to management of a very psychiatrically ill patient population. Given that many psychotropic medications are thought to either promote or prevent seizures, there is ongoing concern about concurrent psychotropic medication and ECT administration. This study examined the effect of psychotropic medications on seizure threshold and duration during ECT stimulus titration. METHODS The study sample consisted of 550 patients receiving ECT stimulus titration at a single site during a 27-month period. Systematic chart review provided clinical data, including patients' demographics, psychiatric diagnoses, medications administered in the 48 hours before ECT, and information on the ECT procedure. Referring psychiatrists were advised to discontinue lithium before ECT but otherwise managed psychotropic medications as clinically indicated. A fixed charge titration schedule was used to estimate seizure threshold. Electroconvulsive therapy motor seizure duration was estimated by the cuff method, and electroencephalogram seizure duration was estimated by review of a 2-lead strip. RESULTS Administration of psychotropic medications, including benzodiazepines, antiepileptics, selective serotonin reuptake inhibitors, tricyclic and tetracyclic antidepressants, bupropion, and stimulants, was not associated with seizure threshold as estimated by electrical charge eliciting a generalized seizure or duration during the initial ECT titration. Tricyclic and tetracyclic antidepressant dosage was associated with seizure threshold. CONCLUSIONS Psychotropic medications may have little effect on seizure threshold and duration during titration of electrical dose at ECT initiation. Integrating this work with other literature supports making recommendations for medication discontinuation before ECT on an individual basis.

Abstract
BACKGROUND Electroconvulsive therapy (ECT) is one of the most effective treatments for major depressive disorder (MDD), especially in cases of treatment-resistant MDD. Because of their pharmacological profiles, benzodiazepines (BZDs) are suspected to decrease the efficacy of ECT. This study investigated the effect of BZDs on ECT-induced clinical outcomes and ECT course parameters in patients with MDD. METHOD The impact of BZDs on severity of depression (Montgomery-Asberg Depression Rating Scale scores) and on ECT course parameters (seizure threshold, clinical and electroencephalographic seizure duration) was investigated in 70 patients with MDD who received an ECT course using dose-titration method (22 received concomitant BZDs). RESULTS Lower remission rates (52.0%) and smaller decreases in Montgomery-Asberg Depression Rating Scale scores were observed in the non-BZD group than in the BZD group (81.2%, P = 0.02). There were no significant differences between the 2 groups regarding seizure duration and seizure threshold. LIMITATIONS This was a retrospective study. Impact of BZDs on anxiety and cognition was not assessed. CONCLUSIONS Benzodiazepines increased the clinical efficacy of ECT when delivered using dose-titration method and bitemporal stimulation. Further studied are needed to understand the interaction between BZDs and ECT on clinical outcomes.

Abstract
OBJECTIVE The present study aimed to report the initial seizure threshold (IST) of a brief-pulse bilateral electroconvulsive therapy (BP-BL ECT) in Korean patients with schizophrenia/schizoaffective disorder and to identify IST predictors. METHODS Among 67 patients who received ECT and diagnosed with schizophrenia/schizoaffective disorder based on the criteria of the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision, we included 56 patients who received 1-millisecond BP-BL ECT after anesthesia with sodium thiopental between March 2012 and June 2018. Demographic and clinical information was gathered from electronic medical records, and a multiple regression analysis was conducted to identify predictors of the IST. RESULTS The mean age of the patients was 36.9±12.0 years and 30 (53.6%) patients were male. The mean and median IST were 105.9±54.5 and 96 millicoulombs (mC), respectively. The IST was predicted by age, gender, and dose (mg/kg) of sodium thiopental. Other physical and clinical variables were not associated with the IST. CONCLUSION The present study demonstrated that the IST of 1-ms BP-BL ECT following sodium thiopental anesthesia in Korean patients was comparable to those reported in previous literature. The IST was associated with age, gender, and dose of sodium thiopental.

Abstract
Graph theory, a popular analytic tool for resting state fMRI (rsfMRI) has provided important insights in the neurobiology of depression. We aimed to analyze the changes in the network measures of segregation and integration associated with the administration of ECT in patients with depression and to correlate with both clinical response and cognitive deficits. Changes in normalised clustering coefficient (γ), path length (λ) and small-world (σ) index were explored in 17 patients with depressive episode before 1st and after 6th brief-pulse bifrontal ECT (BFECT) sessions. Significant brain regions were then correlated with differences in clinical and cognitive scales. There was significantly increased γ and σ despite significant increase in λ in several brain regions after ECT in patients with depression. The brain areas revealing significant differences in γ before and after ECT were medial left superior frontal gyrus, left paracentral lobule, right pallidum and left inferior frontal operculum; correlating with changes in verbal fluency, HAM-D scores and delayed verbal memory (last two regions) respectively. BFECT reorganized the brain network topology in patients with depression and made it more segregated and less integrated; these correlated with clinical improvement and associated cognitive deficits.

Influence of depressed patients' expectations prior to electroconvulsive therapy on its effectiveness and tolerability (Exp-ECT): a prospective study. Eur Arch Psychiatry Clin Neurosci 2018; 268:809-817. [PMID: 28940099 DOI: 10.1007/s00406-017-0840-8] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/16/2017] [Accepted: 09/14/2017] [Indexed: 01/08/2023]
Abstract
Electroconvulsive therapy (ECT) is the most effective therapy for severe depressive disorders. Though there are known clinical predictors of response (e.g., higher age, presence of psychotic symptoms), there is a lack of knowledge concerning the impact of patients' expectations on treatment outcome and tolerability in terms of possible placebo/nocebo effects. In 31 patients with unipolar or bipolar depressive disorder, we used a questionnaire to investigate the patients' expectations of ECT effectiveness and tolerability prior to and in the course of the treatment. Additionally, the questionnaire was used after the ECT course for a final assessment. Depressive symptoms and putative side-effects were measured at each time point. General linear models were used to analyze the course of depressive symptoms and patients' expectation of ECT effectiveness and tolerability. ECT significantly reduced depressive symptoms with large effect sizes. Patients' rating of ECT effectiveness decreased in parallel: While responders' rating of ECT effectiveness remained stable on a high level, non-responders' rating decreased significantly. Group difference was significant after, but not prior to and during the treatment. Regarding tolerability, there was a (temporary) significant increase in the severity of self-rated symptoms such as headache and memory impairment. In contrast, patients' expectation and assessment of ECT tolerability remained unchanged, and their expectations prior to ECT had no impact on the occurrence of side-effects. These findings contradict the presence of relevant placebo/nocebo effects in the context of ECT when investigating a population of mostly chronic or treatment resistant patients with moderate to severe depressive disorder.

Abstract
BACKGROUND Although the dosage of electroconvulsive therapy (ECT) stimulus has a major impact on the efficacy and safety of this treatment, the method used to determine an optimal dosage remains a matter of debate. OBJECTIVE We investigated factors influencing the seizure threshold (ST) in a large-sample study and compared age-based and titration dosing methods in terms of charge. METHODS A retrospective study examined data from 503 patients across France and Canada. The patients underwent right unilateral (RUL) or bitemporal (BT) ECT during a titration session before undergoing ECT. Seizure threshold and charge differences between age-based and titration-predicted methods were derived for each RUL and BT patient and compared according to sex, age, and anesthetic agents. RESULTS Based on our results, ST is a function of electrode placement, sex, age, and anesthetic agents. Titration and age-based methods led to completely different patterns of charges for the same electrode placement, especially in elderly and in women in the RUL group. Regression models showed that differences between the age-based and titration methods varied with respect to age, sex, and anesthetic agent. Specifically, significant effects of sex and age were observed for RUL ECT and of sex and anesthetics for BT ECT. CONCLUSIONS This study revealed that several factors significantly influence the prediction of ECT dose, depending on individuals and treatment modalities. Caution should be exercised when using nonindividualized methods to calculate ST.

Abstract
OBJECTIVES To investigate the effect of delaying initiation of electroconvulsive therapy (ECT) after administration of anaesthetic agent and muscle relaxant. METHODS A retrospective cohort study utilizing a case-based analysis comparing number of re-stimulations, length of seizures, number of ECTs per series and stimulation dosage before and after introducing a new treatment regimen. In 2013, ECT was initiated approximately 60-90 seconds after administration of thiopental and succinylcholine. This interval was increased to 120 seconds in 2014. Ninety-three patients were included (40 in 2013 and 53 in 2014). Outcome measures were length of seizure, number of re-stimulations, number of ECTs per series and stimulation dosage. Regression model analyses were conducted with entering year of treatment (2013 vs. 2014), sex and age as covariates. RESULTS We showed that a lowered frequency of re-stimulation was independently associated with the 2014 treatment regimen. No effect of treatment regimen on duration of seizures as measured clinically or by EEG, on number of treatments per series or on stimulation dosage was observed. CONCLUSIONS We found an association between an increased time interval from administration of thiopental and succinylcholine to ECT and a lowered risk of re-stimulations. The current study substantially strengthens the evidence on the benefits of delaying ECT after administration of anaesthetic agent and muscle relaxant.

Abstract
OBJECTIVE It has been suggested that Electroconvulsive Therapy (ECT) might increase the risk of epilepsy but the few patient studies with retrospective data from medical records do not support the hypothesis. The aim of this study was to examine the relationship between ECT and subsequent incident epilepsy in patients with affective disorder. We also explored whether any association varied with number of ECTs and time since last treatment. METHODS All 169,457 patients with first hospital contact for an affective disorder between January 2005 and December 2015 were identified in the Danish National Patient Registry and followed for incident epilepsy from January 2005 until November 2016. The association between ECT and epilepsy was examined using Cox proportional hazard regression with adjustment for gender, age, educational level, comorbid schizophrenia, previous stroke and antidepressant and antipsychotic medication use. RESULTS A total of 5875 patients had at least one ECT and 1873 patients developed epilepsy (Incidence rate: 213 pr. 100,000 person years) during the follow-up of mean 5 years. In patients below age 40 years, ECT was associated with a higher rate of epilepsy after adjustment for covariables (Hazard Ratio (HR) = 1.84; 95% Confidence Intervals (CI) = [1.24-2.74]). In patients aged 41-60 years ECT was not associated with epilepsy, while for those above 60 treated with ECT the rate was lower (HR = 0.57; (95% CI = [0.37-0.89]). CONCLUSION In patients with affective disorders, we found a weak positive association between ECT and subsequent diagnosis of epilepsy in those younger than 40 years, and a weak negative association in patients older than 60 years. The associations might be subject to residual confounding from risk factors related to ECT.

Should Benzodiazepines and Anticonvulsants Be Used During Electroconvulsive Therapy?: A Case Study and Literature Review. J ECT 2017; 33:237-242.

Abstract
OBJECTIVE This study aims to investigate the clinical effects of benzodiazepines or anticonvulsant use during a course of electroconvulsive therapy (ECT). METHOD A case report study of a patient who received ECT with and without concomitant flurazepam and pregabalin is presented. The literature on the use of benzodiazepines and anticonvulsants during ECT is reviewed. RESULTS A woman with treatment resistant depression received a course of ECT while taking flurazepam and pregabalin, but seizures were of short duration and symptomatic improvement was minimal. After discontinuation of flurazepam and pregabalin, a course of right unilateral ultrabrief ECT was associated with adequate seizures and remission of depression and suicidal ideation. Our literature review suggests that benzodiazepines decrease seizure duration, but most evidence shows no association with increased seizure threshold. One prospective RCT and 3 large retrospective studies found that benzodiazepines compromise the efficacy of unilateral but not bilateral ECT. Regarding anticonvulsants, several studies had varied and contradictory results on their effect on seizure duration and seizure threshold. Of the 2 large retrospective studies and 3 RCTs, only 1 retrospective study showed that anticonvulsants decrease the efficacy of ECT. CONCLUSIONS Judicious assessment of all medications used in combination with ECT is recommended. Overall, published studies suggest that benzodiazepines and anticonvulsants impact the clinical outcomes of ECT less than what would be expected given their pharmacologic effects. However, there are significant gaps in the literature, including a lack of study on suprathreshold stimulation of right unilateral ECT and the possibility of a greater effect with higher medication doses.

Abstract
OBJECTIVE To analyze the relationship between seizure threshold (ST) and psychotropic drugs in patients treated with ECT. METHODS We examined clinical data from 43 patients. ST was titrated at each treatment session. We examined associations between ST and psychotropic drugs using multivariate correlation analyses. Data are presented as initial ST, the difference in ST between the first and 10th sessions (ΔST10th), and the mean difference in ST between the first and last sessions (mean ΔSTlast). RESULTS Multivariate regression analyses showed associations between initial ST and the total chlorpromazine-equivalent dose of antipsychotics (β=0.363, p<0.05). The total fluoxetine-equivalent dose of antidepressants was associated with ΔST10th (β=0.486, p<0.01) and mean ΔSTlast (β=0.472, p<0.01). CONCLUSION Our study elucidated possible effects of psychotropic drugs on ST shifts. Larger doses of antipsychotics were associated with higher initial ST, whereas higher doses of antidepressants were associated with stronger shifts in ST.
