The Incidence of Post-Electroconvulsive Therapy Headache: A Systematic Review

Electroconvulsive Therapy in Children and Adolescents in Germany-A Case Series From 3 University Hospitals

OBJECTIVE

Electroconvulsive therapy (ECT) is a well-established, safe, and efficacious treatment for severe psychiatric disorders. In children and adolescents, it is used much less frequently than in adults, likely because of a lack of knowledge.

METHODS

We retrospectively analyzed all patients aged 12 to 17 years who completed a course of ECT at 3 psychiatric university hospitals in Germany between 2010 and 2020. Clinical Global Impression Severity (CGI-S) scores were assessed based on electronic medical records. Changes in CGI-S scores were assessed using a paired samples t test. Predictors for response and remission were assessed using binomial logistic regression.

RESULTS

We included 32 patients. The CGI-S scores improved significantly from before to after ECT treatment (6.9 vs 3.9, t = 10.0, P < 0.01). A total of 40.6% of patients responded (CGI ≤ 3) and 21.9% remitted (CGI ≤ 2). The number of ineffective medication trials in the 6 months before ECT treatment was significantly associated with response (odds ratio, 0.54; P = 0.028) and remission (odds ratio, 0.31; P = 0.048). Five patients reported subjective cognitive adverse effects, 2 patients exhibited a prolonged seizure, 1 patient reported headaches, and 1 patient experienced a mild allergic reaction after anesthesia with etomidate. A total of 65.6% of patients experienced no adverse effects at all.

CONCLUSIONS

This retrospective analysis found ECT to be effective and safe in children and adolescents irrespective of their main diagnosis. The reported data point to the importance of an early use of ECT for severe psychiatric diseases in child and adolescent psychiatry.

Fronto-medial electrode placement for electroconvulsive treatment of depression

Electroconvulsive therapy (ECT) is the most effective treatment for severe treatment-resistant depression but concern about cognitive side-effects, particularly memory loss, limits its use. Recent observational studies on large groups of patients who have received ECT report that cognitive side-effects were associated with electric field (EF) induced increases in hippocampal volume, whereas therapeutic efficacy was associated with EF induced increases in sagittal brain structures. The aim in the present study was to determine whether a novel fronto-medial (FM) ECT electrode placement would minimize electric fields in bilateral hippocampi (HIP) whilst maximizing electric fields in dorsal sagittal cortical regions. An anatomically detailed computational head model was used with finite element analysis, to calculate ECT-induced electric fields in specific brain regions identified by translational neuroimaging studies of treatment-resistant depressive illness, for a range of electrode placements. As hypothesized, compared to traditional bitemporal (BT) electrode placement, a specific FM electrode placement reduced bilateral hippocampal electric fields two-to-three-fold, whilst the electric fields in the dorsal anterior cingulate (dAC) were increased by approximately the same amount. We highlight the clinical relevance of this specific FM electrode placement for ECT, which may significantly reduce cognitive and non-cognitive side-effects and suggest a clinical trial is indicated.

Efficacy and safety of electroconvulsive therapy plus medication versus medication alone in acute mania: A meta-analysis of randomized controlled trials

Although some studies have reported the potential efficacy of electroconvulsive therapy (ECT) in the treatment of acute mania, there is no consensus on the matter. Therefore, we performed a meta-analysis to determine the efficacy and safety of ECT combination with medication (ECT-combo) vs. medication alone (Med-alone) in the treatment of acute mania. Randomized controlled trials (RCTs) of ECT-combo versus Med-alone in acute mania were searched in Chinese databases and English databases from their inceptions up to February 2020. Twelve RCTs (including 863 patients, n=863) met our criteria and were included into meta-analysis. The pooled results found that ECT-combo outperformed Med-alone in reducing manic symptoms from baseline to endpoint with a standardized mean difference of -3.50 (95% CI: -4.57, -2.44, p<0.00001). The significant difference occurred after 3-5 treatments or after a 1-week treatment. ECT-combo had significantly increased memory impairment compared to Med-alone. Apart from increased memory impairment in ECT-combo group (SMD=8.33; 95% CI: 2.73 to 25.45, p= 0.0002), no other statistically significant differences in side effects or drop-out rates were found between groups. The results of this meta-analysis suggest that ECT-combo was significantly superior to Med-alone in efficacy and well-tolerated as Med-alone in the acute treatment of mania. However, larger studies with randomized, double-blind design, and standardized treatment regimens are still warranted due to the high heterogeneity of studies included in the present meta-analysis.

[Use of electroconvulsive therapy in adolescents - A retrospective survey on 12- to 17-year-old patients at three university hospitals in Germany]

Use of electroconvulsive therapy in adolescents - A retrospective survey on 12- to 17-year-old patients at three university hospitals in Germany Abstract. Abstract. Background: Electroconvulsive therapy (ECT) is a highly effective and well-researched therapy in adult psychiatry and has been successfully used especially as a treatment for severe depressive, catatonic, and psychotic disorders. Although severe disease progressions also occur in child and adolescent psychiatry, ECT is used much less frequently there. This may be because hardly any data have been collected on the use, effectiveness, and tolerability of ECT in child and adolescent psychiatric patients. This article outlines the application, effectiveness, and tolerability of ECT when applied to young adolescents in Germany. Methods: A retrospective survey on ECT in 29 patients under 18 years of age was conducted at three German university centers. All documented cases were recorded and evaluated for effectiveness and tolerability. In addition, a comprehensive PubMed-based database search was carried out. Results and conclusions: Internationally, there are no meta-analyses or randomized controlled studies and hardly any published cases on electroconvulsive therapy in German child and adolescent psychiatry. Our data on ECT show high efficacy in previously treatment-resistant and severely ill patients. Side effects occurred rarely. There was no evidence of differences between adults and adolescents in indication (depression, catatonia, schizophrenia), effectiveness, tolerability, and negative predictors of response to ECT. The results also suggest that the use of ECT in adolescents should be considered earlier in the treatment course.
