When Can We Predict the Outcome of an Electroconvulsive Therapy Course in Adolescents?: A Retrospective Study

The efficacy of electroconvulsive therapy in adolescent major depressive disorder with suicidal ideation: A propensity score-matched, retrospective cohort study

BACKGROUND

More evidence is needed to validate the use of ECT in adolescent depression. This study aims to compare the effectiveness of electroconvulsive therapy (ECT) to conventional medication therapy for adolescents with major depression with suicidal ideation.

METHODS

In this retrospective cohort study, we reviewed inpatient records from the First Affiliated Hospital of Chongqing Medical University spanning December 2016 to June 2021. We focused on adolescents diagnosed with severe depression presenting with suicidal tendencies. To equalize baseline differences between patients, we used the one-to-one propensity score matching to match patients who received ECT treatment with those who did not. Multivariate regression analysis was utilized to adjust for potential confounders, and subgroup analyses and sensitivity analyses were conducted to verify the robustness of our findings.

RESULTS

Of the 626 patients in this study, 474 underwent ECT treatment while 152 received medication treatment, all aged between 10 and 18 years. Once matched, each group contained 143 patients. The ECT group demonstrated a significantly higher response rate and greater reductions in both Hamilton Depression Rating Scale and Hamilton Anxiety Scale scores (all P < 0.001). Additionally, the ECT group was more effective in reducing suicidal ideation, with fewer individuals retaining such ideation at discharge. In the multivariable regression analysis, both ECT treatment and shorter disease duration were independently linked to enhanced antidepressant efficacy. Subgroup analyses and sensitivity analyses verified the robustness of the main study effect.

CONCLUSIONS

For adolescents with major depressive disorder and suicidal ideation, combining ECT with pharmacotherapy is more effective than pharmacotherapy alone before medications reach full effect.

Electroconvulsive therapy for adolescents with severe depressive episode and suicidality: retrospective comparison between responders and non-responders

BACKGROUND

For adolescents with major depression who exhibit suicidal tendencies, Electroconvulsive Therapy (ECT) is increasingly adopted in clinical practice. Yet, the precise mechanisms behind its effectiveness remain elusive, and studies on factors that influence treatment outcomes are scarce.

METHODS

In this retrospective comparative study, we included all adolescent severe depressive episode patients with suicidal tendencies admitted to the Psychiatry Department of the First Affiliated Hospital of Chongqing Medical University between 2017 and 2021 and received ECT treatment. By collecting data on personal history, medical history, and standard treatment features, we established demographic, disease, medication, and ECT treatment factors variables. Patients were divided into effective and ineffective groups based on the Clinical Global Impressions-Improvement (CGI-I) scale scores, and differences between outcomes were compared. Logistic regression analyses were used to identify factors independently associated with ineffectiveness.

RESULTS

A total of 494 adolescent severe depressive episode patients with suicidal behavior who received ECT were included in this study. According to CGI-I scores, the treatment was effective in 361 patients (73.1%) and ineffective in 133 patients (26.9%). Logistic regression analyses showed that 8 to 12 and 12 to 16 ECT sessions reduced the risk of ineffectiveness compared to fewer than 4 sessions. The risk of ineffectiveness decreased with age and increased with comorbidity with obsessive-compulsive disorder (OCD). Compared to sertraline, escitalopram was associated with a heightened risk of futility, whereas olanzapine and aripiprazole demonstrated a reduced risk when contrasted with quetiapine.

CONCLUSIONS

ECT's ineffectiveness in treating adolescent severe depressive episode with suicidal behavior decreases with age, and comorbidity with OCD significantly increases the risk of treatment failure. Fewer than 8 ECT sessions may hinder achieving satisfactory results.

Electroconvulsive therapy in children and adolescents: results from a population‑based study utilising the Swedish National Quality Register

Electroconvulsive therapy (ECT) is effective and safe for adults with severe depression, but less studied in adolescents. Here, we examined the indications, prevalence, practice, response and remission rates, and side effects in young people treated with ECT in Sweden. We also examined the usage of ECT in the transition to adult psychiatry. Using data from national patient registers and the Swedish National Quality Register for ECT (Q-ECT), we identified patients aged up to 19 years treated with ECT over a 5-year study period. Response and remission rates were analysed using the Clinical Global Impression (7-point scale)-Improvement (CGI-I) and Severity (CGI-S). A total of 118 individuals were identified, of which 105 were also enrolled in the Q-ECT. The most common indication for ECT was depression (68%; n = 80). Adolescents aged < 18 years were more severely ill before treatment than those aged 18 years (P < 0.01). Three of the hospitals in Sweden treated the majority of adolescents < 18 years old. The median number of sessions in each ECT series was seven. Unilateral placement of the electrodes was the most common (88%; n = 99). Fifty-seven percent (n = 54) of the patients responded (CGI-I, 1-2) to the treatment; remission (CGI-S, 1-2) was achieved by 32% (n = 30). Psychotic symptoms were associated with a higher response rate in patients with depression (P = 0.038). A deterioration of memory compared to pre-treatment was reported in six patients. ECT was associated with high response and remission rates in adolescents with severe psychiatric disorders after non-response to medication.

Response rate and safety of antidepressants combined with electroconvulsive therapy in adolescent depression: Real-world clinical application

BACKGROUND

METHODS: This study included 210 depression patients receiving antidepressants and ECT. The symptoms of depression were examined with the Hamilton Depression Scale (HAMD) and Clinical Global Impressions Scale (CGI) at baseline and the end of treatment. Response and safety were compared among adolescent and adult patients.

RESULTS

For adolescents, the response rate (much improved or very much improved) was 80.9 %, and CGI-Severity (CGI-S), HAMD, and suicide factor scores were significantly changed as compared to baseline (P < 0.001), results of which were similar to the adult group. There were no significant differences in HAMD, CGI scores between adolescent and adult depression before or after treatment (P > 0.05). Notably, adolescents expressed stronger suicidal intent than adults, and ECT observably relieved it. Side effects (memory problems, headache, nausea/vomiting, muscle soreness) in adolescents were not statistically different from those in adults (P > 0.05).

LIMITATIONS

As data were derived from a single center, the generalizability of results may be limited, and the potential factors affecting the efficacy of ECT were not further explored.

CONCLUSION

Antidepressants combined with ECT are associated with high response rate and safety for treating depression, regardless of age. A stronger expression of suicide ideation was observed in depressed adolescents, and side effects of ECT were similar to the adults.

Systematic review: Electroconvulsive therapy for treatment-resistant mood disorders in children and adolescents

Electroconvulsive therapy (ECT) is a well-established treatment for adults with mood disorders. However, its use in child and adolescent populations is less common. At the same time, approximately 60% of child and adolescent patients do not respond satisfactorily to first-line treatments for mood disorders. Given the need for effective treatments for severe mood disorders in adolescents and the low use rate of ECT, this systematic review examines the existing literature on the effectiveness and adverse effect profile of ECT when used for treatment-resistant mood disorders in children and adolescents. Searches were conducted in Medline, Embase, and PsycInfo using search terms related to (1) children and adolescents, (2) mood disorders, and (3) ECT. Searches identified 1715 unique articles. The full text of 71 selected articles were reviewed, leading to 41 studies included in the study. A standardized data extraction tool was used to collect key information from each study (i.e. author and publication year, objectives, participants and setting, design, measures, clinical outcomes, and side effects). As most of the studies found were case series, the Joanna Briggs Institute Case Series Critical Appraisal tool was used to assess quality. Studies were summarized qualitatively by comparing findings across key study parameters. Our review identified 41 studies for inclusion. Twenty were case series, two were case-control studies, and nineteen were case reports. Overall treatment response rates ranged from 51 to 92%, with patients receiving an average of 12 treatments. Among studies with n > 30, response rates were largely 70-82% for depression and 87-90% for mania. Seven studies used the Mini-Mental State Exam and found no evidence of significant post-treatment cognitive impairment. The majority of side effects were minor and transient. Tardive seizure was reported in 4 (0.6%) patients. ECT was discontinued early due to side effects in 11 (1.5%) cases. No fatalities were reported. Our data suggest that ECT is safe and effective for the treatment of mood disorders in child and adolescent populations, and should be considered in severe and treatment-refractory cases. Controlled studies with objective measures and long-term follow-up are needed to advance the evidence base.

Evaluation of Electroconvulsive Therapy in Adolescents With Major Depressive and Bipolar Disorders: A Retrospective Analysis

OBJECTIVE

This study aims to provide an evaluation of electroconvulsive therapy (ECT) in hospitalized adolescents with major depressive and bipolar disorders by examining its treatment outcomes as well as comparing it with outcomes of hospitalized patients, treated as usual (TAU).

METHODS

This is a retrospective study based on medical records documented between April 2011 and December 2017 from Beijing An Ding Hospital. Patients were diagnosed according to the International Classification of Diseases, Tenth Revision . The study included 288 inpatients, with 2 groups of 171 patients treated by ECT and 117 TAU. The primary outcome was measured using the severity subscale of Clinical Global Impression. Mann-Whitney U test, χ2 test, and linear regression with mixed models were used to analyze the data.

RESULTS

Symptom severity reduced significantly for both groups ( β = -0.62, t975.93 = -20.54, P < 0.001). The TAU group was associated with lower score on the severity subscale of Clinical Global Impression ( β = 0.28, t980.32 = 8.36, P < 0.001). The ECT group had a higher remission rate (28.65%) than the TAU group (16.24%), but the time required for remission was longer ( U [ NECT = 49, NTAU = 19] = 615, z = 2.10, P = 0.04). Adverse events of ECT were barely observed.

CONCLUSION

Electroconvulsive therapy is an efficacious and safe treatment for adolescents. However, as the superiority in efficacy was not evident in ECT group, its prescription should be prudently considered for younger patients who respond well to other treatments.

Morbidity Due to Disparity in Pediatric Electroconvulsive Therapy

Dr. Miller and colleagues recently submitted a Letter to the Editor discussing current state laws that result in disparity of electroconvulsive therapy (ECT) availability.¹ In this current letter, we present a case of treatment-resistant childhood-onset schizophrenia (COS), with morbidity due to limited access to ECT. The patient and his family presented from Kentucky to Tennessee, despite less legislative regulation in the former. The patient's family provided informed consent for this report to be published.

A retrospective case series of electroconvulsive therapy in the management of depression and suicidal symptoms in adolescents

OBJECTIVE

Major depressive disorder (MDD) with suicidal symptoms is common in adolescents. Electroconvulsive therapy (ECT) is highly effective in the treatment of MDD. We have described its use and outcome in a case series of adolescents with depression and suicidal symptoms receiving ECT.

METHODS

We analyzed 362 adolescents aged from 12 to 17 who had received ECT between year 2015 and 2021. A total of 278 subjects were found to meet the inclusion criteria, where depressive symptoms were assessed by HDRS and suicidal symptoms were assessed by HDRS item 3. Their sociodemographic, clinical, and treatment information were retrieved through these records for this study.

RESULTS

The mean ± SD age of subjects was 15.41 ± 1.50 years and male sex was 14.7% (n = 41). Comorbid diagnoses were present in 104 patients (37.4%). The ECT sessions ranged from 6 to 12 times. All the patients took antidepressants, with sertraline (n = 182; 65.5%) being the most widely used. Majority of patients also received benzodiazepines. ECT was significantly effective in adolescents with depression and suicidal symptoms in evaluation by HDRS, HDRS item 3, CGI-S (p &lt; .001) pre/post-ECT. The response rate of MDD patients was 52%, with suicidal ideation (SI) at 49%, and 54% in MDD with suicide attempt (SA). The change of CGI-S scores showed no significant differences between various subgroups of sex and comorbid (p&gt;.05), but there were significant differences between subgroups of suicidal symptoms (p &lt; .001). ECT was generally safe with subjective memory complaint (n = 189, 68.0%), headache (n = 150, 54.0%), body pain (n = 28, 10.1%), delirium (n = 95, 34.2%), and nausea (n = 31, 11.2%) as possible side effects following ECT.

CONCLUSION

In this study, ECT was found to decrease depressive and suicidal symptoms in adolescents, and the side effect was acceptable. ECT showed better outcome for MDD with SA compared to MDD with SI.

Electroconvulsive Therapy in Children and Adolescents: A Systematic Review of Current Literature and Guidelines

ABSTRACT

There is a lack of studies regarding the efficacy of electroconvulsive therapy (ECT) in children and adolescents. In this study, we aimed to assess benefits and harms of ECT in children and adolescents with major psychiatric diseases. We conducted a systematic search in PubMed, EMBASE, and PsycINFO for peer-reviewed articles written in English regarding the use of ECT as treatment for major psychiatric diseases in children and adolescents. This study consists of 192 articles, mostly case studies (n = 50), reviews and overview articles (n = 52), and retrospective studies (n = 30). We present an overview of evidence for ECT in children and adolescents with mood disorders, catatonia, schizophrenia, intellectual disability, self-injurious behavior, and other indications. This article is also a summary of international guidelines regarding the use of ECT in children and adolescents. We evaluated the overall quality of evidence by using Grading of Recommendations, Assessment, Development and Evaluations and found the overall level of evidence to be of low quality. There are no absolute contra indications for ECT in children and adolescents. Fears regarding cognitive dysfunction have not been reproduced in studies. Electroconvulsive therapy should be considered in severe, treatment-resistant mood disorders, catatonia, and schizophrenia, especially in older adolescents. High-quality studies are warranted to assess the efficacy of ECT, especially in these potentially life-threatening diseases.

The 2020 Royal Australian and New Zealand College of Psychiatrists clinical practice guidelines for mood disorders

OBJECTIVES

To provide advice and guidance regarding the management of mood disorders, derived from scientific evidence and supplemented by expert clinical consensus to formulate s that maximise clinical utility.

METHODS

Articles and information sourced from search engines including PubMed, EMBASE, MEDLINE, PsycINFO and Google Scholar were supplemented by literature known to the mood disorders committee (e.g. books, book chapters and government reports) and from published depression and bipolar disorder guidelines. Relevant information was appraised and discussed in detail by members of the mood disorders committee, with a view to formulating and developing consensus-based recommendations and clinical guidance. The guidelines were subjected to rigorous consultation and external review involving: expert and clinical advisors, key stakeholders, professional bodies and specialist groups with interest in mood disorders.

RESULTS

The Royal Australian and New Zealand College of Psychiatrists mood disorders clinical practice guidelines 2020 (MDcpg²⁰²⁰) provide up-to-date guidance regarding the management of mood disorders that is informed by evidence and clinical experience. The guideline is intended for clinical use by psychiatrists, psychologists, primary care physicians and others with an interest in mental health care.

CONCLUSION

The MDcpg²⁰²⁰ builds on the previous 2015 guidelines and maintains its joint focus on both depressive and bipolar disorders. It provides up-to-date recommendations and guidance within an evidence-based framework, supplemented by expert clinical consensus.

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

Headache is a common side effect of electroconvulsive therapy (ECT), but reports on its incidence vary widely. A broad array of treatment regimens have been proposed in the literature. The pathophysiology of post-ECT headache is unclear but a vascular origin has been suggested. A systematic literature search was executed in PubMed and Embase to identify relevant articles. Articles were screened on title, abstract, and full text according to predefined inclusion and exclusion criteria. Study characteristics and results concerning the incidence of post-ECT headache were extracted, and a weighted mean incidence was calculated. Forty-seven relevant articles were found, of which 36 reported on the incidence of post-ECT headache in patients and 9 on the incidence in sessions. The incidence of post-ECT headache varied greatly in the literature. The weighted mean incidence in patients was 32.8%, as 786 of a total population of 2399 patients experienced headache. The weighted mean incidence in sessions was between 9.4% (246 of 2604 sessions) and 12.1% (236/1958 sessions). The variation in incidences of post-ECT headache found might be due to different methods of measuring headache, different study designs, and different drugs used for anesthesia. The mean-weighted incidence of post-ECT headache in patients was 32.8% and in sessions between 9.4% and 12.1%.

Electroconvulsive therapy in an adolescent with bipolar disorder, substance use, and body dysmorphic disorder comorbidity: case report

Our case report is on the use of electroconvulsive treatment (ECT) in an adolescent with Bipolar Disorder (BPD), Substance Use Disorder (SUD) and comorbid Body Dysmorphic Disorder (BDD). In our case, ECT was not considered at the first stage, but we encountered medication noncompliance and treatment resistance. Symptoms of body dysmorphic disorder completely disappeared after ECT, which is consistent with the literature. ECT is a treatment with a low side effect profile in treatment-resistant cases. In addition, it will be useful to increase the knowledge and experience of clinicians on ECT and to provide conditions for ECT in child and adolescent psychiatric clinics.

Acute Phase Treatment Outcomes of Electroconvulsive Therapy in Adolescents and Young Adults

OBJECTIVE

Electroconvulsive therapy (ECT) is a highly efficacious, well-tolerated treatment in adults. Little is known, however, about its effectiveness in adolescents and young adults. Our objectives were to assess clinical outcomes after acute phase ECT in adolescents and young adults and determine whether screening positive or negative for a substance use disorder (SUD) is associated with differences in treatment outcomes.

METHODS

Study sample consisted of all patients 16 to 25 years old who received ECT from May 2011 to August 2016 and who completed self-reported SUD screens and the Behavior and Symptom Identification Scale-24 (BASIS-24) initially and completed the BASIS-24 again after the fifth ECT treatment. For 5 BASIS-24 domains, longitudinal changes in mean domain scores were assessed; mean changes by SUD screening status were also examined using linear mixed models.

RESULTS

One hundred ninety adolescents and young adults, with mean age 21.0 ± 2.6 years, met inclusion criteria. Electroconvulsive therapy was associated with significant clinical improvement (score decreases) in all 5 BASIS-24 domains during the acute phase treatment (P < 0.001). Sixty-four percent (122/190) screened positive for SUD. Compared with adolescents and young adults screening negative for SUD, those screening positive for co-occurring SUD had greater improvement in depression/functioning (-0.37 ± 0.14, P = 0.009), interpersonal relationships (-0.27 ± 0.13, P = 0.045), and emotional lability (-0.27 ± 0.14, P = 0.044) domains after the fifth ECT treatment.

CONCLUSIONS

Electroconvulsive therapy in adolescents and young adults was associated with significantly improved clinical outcomes during acute phase treatment. Adolescents and young adults screening positive for SUD had better acute phase ECT outcomes in self-reported depression/functioning, interpersonal relationships, and emotional lability than those screening negative. More research is needed to clarify adolescents and young adult patient characteristics that may be associated with differential ECT outcomes.

Non-suicidal self-injury and electroconvulsive therapy: Outcomes in adolescent and young adult populations

BACKGROUND

Electroconvulsive (ECT) therapy is a highly effective treatment for severe depression. Although the clear majority of patients respond to ECT, not all do, and we still lack good predictors for ECT outcome, especially in adolescents and young adults. One clinical variable that has been associated with reduced likelihood of ECT antidepressant response in adults is comorbid borderline personality disorder. As self-injurious behavior is often a feature of borderline personality disorder, we hypothesized that adolescent and young adult patients with a history of non-suicidal self-injury (NSSI), who were being treated for major depression with ECT, would have a poorer response than patients without such a history.

METHODS

We conducted a retrospective chart review of 48 patients treated with ECT for depression at The Johns Hopkins Hospital between the ages of 14 and 25.

RESULTS

Initial analyses showed that the presence of NSSI was not associated with ECT outcomes. However, sub-group analyses suggested that it was associated with response to ECT and overall remission among female patients. Specifically, the results suggested that in adolescent and young adult female ECT patients, the presence of NSSI was associated with lower odds of response (OR: 0.04; 95% CI: 0.0004, 0.81, p = 0.03) and remission (OR: 0.09; 95% CI: 0.0000, 0.81, p = 0.03), and a greater mean number of treatments (5.83; 95% CI: 0.27, 11.39, p = 0.04) compared with patients without NSSI.

CONCLUSIONS

Clearly, the finding that NSSI may be associated with poorer ECT outcomes among female patients needs to be replicated. Nonetheless, our data suggest caution when considering an adolescent or young adult woman for a course of ECT.

Use of electroconvulsive therapy in adolescents with schizophrenia in China

BACKGROUND

Electroconvulsive therapy (ECT) is an effective treatment for psychiatric disorders such as schizophrenia, major depression and bipolar disorder. However, few studies have addressed the use of ECT in adolescents with schizophrenia. The aims of our study were to investigate the frequency of ECT, and its relationship with clinical and demographic correlates among adolescents with schizophrenia in China.

METHODS

The study was a retrospective study and conducted in the Child and Adolescent Psychiatry Department of Beijing Anding Hospital, and adolescents with schizophrenia over a period of 10 years (2007-2016) were enrolled. The demographic and clinical data were collected from the electronic chart management system.

RESULTS

A total of 835 patients were included, 411/835 (49.2%) of the adolescent inpatients diagnosed with schizophrenia were in ECT group. There were significant differences in the sex, age, high risk for aggression and suicide, family history of psychiatric disorders and concomitant psychotropic medication (antidepressants and benzodiazepines) between the ECT and non-ECT groups. Multiple logistic regression analysis revealed that ECT use was independently and positively associated with sex, high risk for suicide.

CONCLUSIONS

In a major psychiatric center in China, the use of ECT was common, and reasons for the high use of ECT for adolescent patients in this hospital should warrant urgent investigations.
