Has the practice and outcome of ECT in adolescents changed? findings from a whole-population study

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.

Acceptability, safety and tolerability of antidepressant repetitive transcranial magnetic stimulation for adolescents: A mixed-methods investigation

OBJECTIVE

Major depressive disorder (MDD) is relatively common in adolescence, with far-reaching impacts. Current treatments frequently fail to alleviate depression severity for a substantial portion of adolescents. Repetitive transcranial magnetic stimulation (rTMS) may assist with this unmet clinical need. However, little is known about adverse events (AEs) experienced by adolescents receiving rTMS, subjective treatment experiences of adolescents and their parents, or treatment acceptability.

METHODS

Fourteen adolescents (16.5 years ± 1.2; 71.4% female) with MDD received 20 sessions of either high-frequency (10 Hz; n = 7) left dorsolateral prefrontal cortex (DLPFC) or low-frequency (1 Hz; n = 7) right DLPFC rTMS. AEs were monitored at baseline and at weekly intervals via New York State Psychiatric Institute Side Effects Form for Children and Adolescents. Eight adolescents and nine parents participated in interviews regarding subjective treatment experience, analysed via content analysis.

RESULTS

Drowsiness and lethargy were common AEs, reported by 92.3% of participants in week one. Number of AEs decreased throughout treatment course (after 5 treatments: M = 11.23, SD = 5.00; after 20 treatments: M = 8.92, SD = 5.95). Thirty-five AEs emerged during treatment, most commonly transient dizziness. Frequency, severity, and number of AEs reported were equivalent between treatment groups. Treatment adherence and satisfaction were high. Qualitative findings identified three themes relating to rTMS experience: Preparation and connection; Physical experience of treatment; and Perceived role of treatment.

LIMITATIONS

Sample size was small, therefore findings are preliminary.

CONCLUSIONS

rTMS was an acceptable treatment for adolescent MDD, from both adolescents' and parents' perspectives, and was safe and well-tolerated, as AE frequency and type did not differ from rTMS treatment courses in adults.

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.

Royal Australian and New Zealand College of Psychiatrists professional practice guidelines for the administration of electroconvulsive therapy

OBJECTIVES

To provide guidance for the optimal administration of electroconvulsive therapy, in particular maintaining the high efficacy of electroconvulsive therapy while minimising cognitive side-effects, based on scientific evidence and supplemented by expert clinical consensus.

METHODS

Articles and information were sourced from existing guidelines and the published literature. Information was revised and discussed by members of the working group of the Royal Australian and New Zealand College of Psychiatrists' Section for Electroconvulsive Therapy and Neurostimulation, and findings were then formulated into consensus-based recommendations and guidance. The guidelines were subjected to rigorous successive consultation and external review within the Royal Australian and New Zealand College of Psychiatrists, involving the full Section for Electroconvulsive Therapy and Neurostimulation membership, and expert and clinical advisors and professional bodies with an interest in electroconvulsive therapy administration.

RESULTS

The Royal Australian and New Zealand College of Psychiatrists' professional practice guidelines for the administration of electroconvulsive therapy provide up-to-date advice regarding the use of electroconvulsive therapy in clinical practice and are informed by evidence and clinical experience. The guidelines are intended for use by psychiatrists and also others with an interest in the administration of electroconvulsive therapy. The guidelines are not intended as a directive about clinical practice or instructions as to what must be done for a given patient, but provide guidance to facilitate best practice to help optimise outcomes for patients. The outcome is guidelines that strive to find the appropriate balance between promoting best evidence-based practice and acknowledging that electroconvulsive therapy is a continually evolving practice.

CONCLUSION

The guidelines provide up-to-date advice for psychiatrists to promote optimal standards of electroconvulsive therapy practice.

The emerging role for repetitive transcranial magnetic stimulation in optimizing the treatment of adolescent depression

Major depressive disorder (MDD) in adolescents is a common illness and significant public health problem. Treatment is challenging because of recurrences and limited modalities. Selective serotonin reuptake inhibitors and cognitive behavioral therapy are considered the standard of care in severe or treatment-resistant MDD in this age group. However, responses to these interventions are often suboptimal. A growing body of research supports the efficacy of repetitive transcranial magnetic stimulation (rTMS) for the treatment of MDD in adults. Induced seizures are a primary safety concern, although this is rare with appropriate precautions. There is, however, limited experience with rTMS as a therapeutic intervention for adolescent psychiatric disturbances. This review will summarize the rTMS efficacy and safety data in adults and describe all published experience with adolescent MDD. Applications in other adolescent psychiatric illnesses such as schizophrenia and attention-deficit/hyperactivity disorder are reviewed. Safety and ethical issues are paramount with investigational treatments in adolescent psychiatric illnesses. However, further research with rTMS in adolescent MDD is imperative to establish standards for optimal stimulation site, treatment parameters, and its role in treatment algorithms. These may diverge from adult data. Early intervention with neuromodulation could also hold the promise of addressing the developmental course of dysfunctional neurocircuitry.

The management of individuals with bipolar disorder: a review of the evidence and its integration into clinical practice

Bipolar disorder is a common, debilitating, chronic illness that emerges early in life and has serious consequences such as long-term unemployment and suicide. It confers considerable functional disability to the individual, their family and society as a whole and yet it is often undetected, misdiagnosed and treated poorly. In the past decade, many new treatment strategies have been trialled in the management of bipolar disorder with variable success. The emerging evidence, for pharmacological agents in particular, is promising but when considered alone does not directly translate to real-world clinical populations of bipolar disorder. Data from drug trials are largely based on findings that identify differences between groups determined in a time-limited manner, whereas clinical management concerns the treatment of individuals over the life-long course of the illness. Considering the findings in the context of the individual and their particular needs perhaps best bridges the gap between the evidence from research studies and their application in clinical practice. Specifically, only lithium and valproate have moderate or strong evidence for use across all three phases of bipolar disorder. Anticonvulsants, such as lamotrigine, have strong evidence in maintenance; whereas antipsychotics largely have strong evidence in acute mania, with the exception of quetiapine, which has strong evidence in bipolar depression. Maintenance data for antipsychotics is emerging but at present remains weak. Combinations have strong evidence in acute phases of illness but maintenance data is urgently needed. Conventional antidepressants only have weak evidence in bipolar depression and do not have a role in maintenance therapy. Therefore, this paper summarizes the efficacy data for treating bipolar disorder and also applies clinical considerations to these data when formulating recommendations for the management of bipolar disorder.

Managing Psychotic Illness in Young People: A Practical Overview

  The management of early onset psychosis poses a significant challenge to professionals working in Child and Adolescent Mental Health Services. Young people with psychotic illness often present with a mixed clinical picture and a wide variety of attendant issues. Over the last decade there has been accumulating research, mainly based on work with adults, regarding the efficacy and effectiveness of medical and psychosocial interventions for patients with schizoaffective spectrum disorders. This article takes a symptoms-based approach, collating and summarising recent evidence, where it exists, regarding best practice when managing young people affected by schizophrenia, schizoaffective or bipolar affective disorder.

Electroconvulsive therapy and transcranial magnetic stimulation: can they be considered valid modalities in the treatment of pediatric mood disorders?

Depression in children and adolescents is a severe and debilitating disorder and can be life-endangering. Even when it is not life-endangering, however, it has a grave impact on the quality of life of youngsters and their families, and interferes with normal growth and development. In recent years, the field of child psychiatry has become more aware of the limited applicability of data from the adult literature to children and adolescents and the limited resources that child psychiatrists have in treating depression. This awareness substantiates the need to define the place of electroconvulsive therapy and transcranial magnetic stimulation in the treatment of pediatric depression.

Electroconvulsive therapy practice in Western Australia

OBJECTIVES

Despite the continued wide use of electroconvulsive therapy (ECT), there is little empirical research documenting numbers and characteristics of recipients of ECT, or the number of ECT administrations in various jurisdictions. This study aimed to further develop an Australian perspective on the practice of ECT, with particular emphasis on its use with children and older adults.

METHODS

The Mental Health Information System of Western Australia (WA) and records from State psychiatric hospitals were examined for data on ECT use over the period from 1997 to 2001.

RESULTS

Most Western Australia recipients of ECT were adult women who were diagnosed with affective disorders. Although the number of ECT recipients rose dramatically each year, ECT usage appeared to be a constant proportion of the psychiatric population in WA during a 5-year period in association with increased numbers of psychiatric patients.

CONCLUSIONS

Use of ECT in WA was at a lower rate than previously reported for Victoria, and notably lower than for older adults in NSW. As in most recent surveys, affective disorders were the most common diagnosis among recipients of ECT. The creation of a more comprehensive State ECT register is recommended to allow more accurate estimations of the frequency of ECT administrations in future, and facilitate more effective and efficient monitoring of ECT practice.

Transcranial magnetic stimulation in persons younger than the age of 18

OBJECTIVES

To review the use of transcranial magnetic stimulation (single-pulse TMS, paired TMS, and repetitive TMS [rTMS]) in persons younger than the age of 18 years. I discuss the technical differences, as well as the diagnostic, therapeutic, and psychiatric uses of TMS/rTMS in this age group.

METHODS

I evaluated English-language studies from 1993 to August 2004 on nonconvulsive single-pulse, paired, and rTMS that supported a possible role for the use of TMS in persons younger than 18. Articles reviewed were retrieved from the MEDLINE database and Clinical Scientific index.

RESULTS

The 48 studies reviewed involved a total of 1034 children ages 2 weeks to 18 years; 35 of the studies used single-pulse TMS (980 children), 3 studies used paired TMS (20 children), and 7 studies used rTMS (34 children). Three studies used both single and rTMS. However, the number of subjects involved was not reported.

CONCLUSIONS

Single-pulse TMS, paired TMS, and rTMS in persons younger than 18 has been used to examine the maturation/activity of the neurons of various central nervous system tracts, plasticity of neurons in epilepsy, other aspects of epilepsy, multiple sclerosis, myoclonus, transcallosal inhibition, and motor cortex functioning with no reported seizure risk. rTMS has been applied to psychiatric disorders such as ADHD, ADHD with Tourette's, and depression. Adult studies support an antidepressant effect from repetitive TMS, but there is only one study that has been reported on 7 patients that used rTMS to the left dorsal prefrontal cortex on children/adolescents with depression (5 of the 7 subjects treated responded). Although there are limited studies using rTMS (in 34 children), these studies did not report significant adverse effects or seizures. Repetitive TMS safety, ethical, and neurotoxicity concerns also are discussed.
