Effects of electroconvulsive therapy in adolescents with severe endogenous depression resistant to pharmacotherapy

A Multicenter Retrospective Chart Review on the Effectiveness and Tolerability of Electroconvulsive Therapy in Adolescents and Young Adults With Major Depressive Disorder or Bipolar Depression

BACKGROUND

Major depressive disorder and bipolar depression in adolescents and young adults are prevalent and major contributors to the global burden of disease, whereas effective interventions are limited. Available evidence is insufficient to assess effectiveness and tolerability of electroconvulsive therapy in depressed adolescents and young adults.

METHODS

A retrospective chart review was conducted in patients with major depressive disorder or bipolar depression who underwent electroconvulsive therapy from 2001 to 2021 in 12 centers in the Netherlands. Patients were classified as young (15-25 years) and older adults (26-80 years). Primary outcome was effectiveness, expressed as response (≥50% reduction in rating scale score compared with baseline) and remission. Rating scale scores were cross-sectionally assessed at baseline and at the end of the index course. Outcomes of remitters were included in responders. Secondary outcome was occurrence of subjective cognitive impairment and adverse events. Long-term outcomes were not available.

RESULTS

In the young (n = 57) and older adult (n = 41) group, 40.4% and 56.1% (P = 0.153) of patients achieved response and 28.1% and 39.0% (P = 0.281) remission, respectively. Subjective cognitive impairment (80.5% vs 56.3%; P = 0.001) and transient cardiac arrhythmia (14.6% vs 2.8%; P = 0.020) were reported significantly more frequently in the older adult group.

CONCLUSIONS

Despite significantly more comorbidity of personality disorders, autism spectrum disorders, and anxiety disorders, effectiveness in the young was similar to the older adults. Tolerability was even superior in the young, despite significantly more bilateral treatment. Electroconvulsive therapy could be considered a viable treatment option in depressed adolescents and young adults.

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.

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.

Resting-state functional magnetic resonance imaging-based identification of altered brain the fractional amplitude of low frequency fluctuation in adolescent major depressive disorder patients undergoing electroconvulsive therapy

PURPOSE

While electroconvulsive therapy (ECT) has been repeatedly been shown to effectively and efficiently treat the major depressive disorder (MDD), the mechanistic basis for such therapeutic efficacy remains to be firmly established. As such, further research exploring the ECT-based treatment of MDD in an adolescent population is warranted.

METHODS

This study included 30 treatment-naïve first-episode MDD patients and 30 healthy control (HC) individuals (aged 12-17 years). All participants were scanned using rs-fMRI, and the 30 MDD patients were scanned again after 2 weeks of the ECT treatment period. Intrinsic local activity in each voxel was assessed based on the fractional amplitude of low frequency fluctuation (fALFF) parameter, with all fALFF analyses being completed using the REST application. Correlations between ECT-related changes in fALFF and clinical parameters were additionally examined.

RESULTS

Relative to HCs, MDD patients exhibited increased fALFF values in the right inferior frontal gyrus (ORBinf), inferior occipital gyrus (IOG), and the left middle frontal gyrus (MFG) at baseline. Following ECT, these patients exhibited significant increases in fALFF values in the right medial superior frontal gyrus (SFGmed), dorsolateral superior frontal gyrus (SFGdor), anterior cingulate, and paracingulate gyrus (ACG), median cingulate and paracingulate gyrus (DCG), and left MFG. MDD patient HAMD scores were negatively correlated with fALFF values when analyzing pre-ECT vs. post-HCT ΔHAMD and fALFF values in the right SFGmed, SFGdor, and the left MFG.

CONCLUSION

These data suggest that ECT induced altered fALFF in some regions of the brain, suggesting that these alterations may serve as a neurobiological indicator of ECT effectiveness in MDD adolescents.

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.

[Electroconvulsive Therapy - A beneficial and well tolerated therapy in children and adolescents with schizophrenia]

We report four cases of 12- to 17-year-old patients with schizophrenia, two of them suffering from catatonia, which were treated by ECT. Under a combined treatment with either ziprasidone or clozapine, and electroconvulsive therapy (ECT), they improved markedly. Severity and course of acute schizophrenia were evaluated by the Brief Psychiatric rating Scale (BPRS), severity and course of catatonia were evaluated with the Bush-Francis Catatonia Rating Scale (BFCRS). This article underlines the benefit, the safety and the tolerability of ECT in younger patients with schizophrenic disorders.

Experience, Knowledge, and Attitudes of Child and Adolescent Psychiatrists in Belgium Toward Pediatric Electroconvulsive Therapy

OBJECTIVE

The purpose of the present study was to ascertain the experience, knowledge, and attitudes of child and adolescent psychiatrists toward the use of ECT (electroconvulsive therapy) in children and adolescents in Belgium.

METHODS

A questionnaire was mailed to all the members of the Flemish and Walloon Association of Child and Adolescent Psychiatrists.

RESULTS

Thirty-five percent (n = 151) of the psychiatrists responded to the questionnaire. Sixty-seven percent (n = 101) rated their knowledge about ECT in children and adolescents as nil or negligible. Only one percent (n = 2) estimated their knowledge to be advanced. Fifteen percent (n = 22) were aware of a minor treated with ECT. Ten (n = 16) and thirty-one percent (n = 47) believed that ECT is a safe treatment for children and adolescents, respectively. Only six percent (n = 10) would recommend ECT for a major psychiatric disorder in a child, whereas thirty-eight percent (n = 58) for an adolescent. Fifty-three percent (n = 71) regarded ECT as a treatment of last resort. A significant correlation was identified between knowledge and attitudes toward the use of ECT in minors. Respondents with some or advanced knowledge perceived ECT as a safer and a more effective treatment option than those with negligible knowledge. Most (91%, n = 138) of the child and adolescent psychiatrists are enthusiastic to learn more about the use of ECT in minors.

CONCLUSIONS

Flemish and Walloon child and adolescents psychiatrists have very little experience with using ECT in minors. They self-estimated their knowledge as negligible but are keen to learn more about this treatment option. The lack of knowledge likely explains the rare use of ECT in Belgium for children and adolescents with serious psychiatric disorders.

A review of repetitive transcranial magnetic stimulation for adolescents with treatment-resistant depression

This review examines the efficacy and safety of repetitive transcranial magnetic stimulation (rTMS) as a treatment for treatment-resistant depression in adolescents. A systematic review of six databases was conducted. Ten multi-subject trials, all uncontrolled, and five case reports met inclusion criteria. Twelve studies focused on treatment efficacy, whereas three studies focused exclusively on adverse events. All efficacy studies focused on adolescents only; 10 of these studies indicated that rTMS may demonstrate some benefit. Improvement within 2-8 weeks was reported in most studies, with a few studies indicating potential long-term benefits. A variety of adverse events occurred including scalp pain, which was the most common, as well as seizures. Controlled studies of rTMS are warranted to further examine whether this treatment is a potential option for adolescents with treatment-resistant depression.

Electroconvulsive therapy use in adolescents: a systematic review

BACKGROUND

Considered as a moment of psychological vulnerability, adolescence is remarkably a risky period for the development of psychopathologies, when the choice of the correct therapeutic approach is crucial for achieving remission. One of the researched therapies in this case is electroconvulsive therapy (ECT). The present study reviews the recent and classical aspects regarding ECT use in adolescents.

METHODS

Systematic review, performed in November 2012, conformed to the PRISMA statement.

RESULTS

From the 212 retrieved articles, only 39 were included in the final sample. The reviewed studies bring indications of ECT use in adolescents, evaluate the efficiency of this therapy regarding remission, and explore the potential risks and complications of the procedure.

CONCLUSIONS

ECT use in adolescents is considered a highly efficient option for treating several psychiatric disorders, achieving high remission rates, and presenting few and relatively benign adverse effects. Risks can be mitigated by the correct use of the technique and are considered minimal when compared to the efficiency of ECT in treating psychopathologies.

Treatment resistant adolescent depression with upper airway resistance syndrome treated with rapid palatal expansion: a case report

Introduction

To the best of our knowledge, this is the first report of a case of treatment-resistant depression in which the patient was evaluated for sleep disordered breathing as the cause and in which rapid palatal expansion to permanently treat the sleep disordered breathing produced a prolonged symptom-free period off medication.

Case presentation

An 18-year-old Caucasian man presented to our sleep disorders center with chronic severe depression that was no longer responsive to medication but that had recently responded to electroconvulsive therapy. Ancillary, persistent symptoms included mild insomnia, moderate to severe fatigue, mild sleepiness and severe anxiety treated with medication. Our patient had no history of snoring or witnessed apnea, but polysomnography was consistent with upper airway resistance syndrome. Although our patient did not have an orthodontic indication for rapid palatal expansion, rapid palatal expansion was performed as a treatment of his upper airway resistance syndrome. Following rapid palatal expansion, our patient experienced a marked improvement of his sleep quality, anxiety, fatigue and sleepiness. His improvement has been maintained off all psychotropic medication and his depression has remained in remission for approximately two years following his electroconvulsive therapy.

Conclusions

This case report introduces the possibility that unrecognized sleep disordered breathing may play a role in adolescent treatment-resistant depression. The symptoms of upper airway resistance syndrome are non-specific enough that every adolescent with depression, even those responding to medication, may have underlying sleep disordered breathing. In such patients, rapid palatal expansion, by widening the upper airway and improving airflow during sleep, may produce a prolonged improvement of symptoms and a tapering of medication. Psychiatrists treating adolescents may benefit from having another treatment option for treatment-resistant depression.

Treatment-resistant depression in adolescents: review and updates on clinical management

Treatment-resistant depression (TRD) in adolescents is prevalent and impairing. We here review the definition, prevalence, clinical significance, risk factors, and management of TRD in adolescents. Risk factors associated with TRD include characteristics of depression (severity, level of hopelessness, and suicidal ideation), psychiatric and medical comorbidities, environmental factors (family conflict, maternal depression, and history of abuse), and pharmacokinetics and other biomarkers. Management options include review of the adequacy of the initial treatment, re-assessment for the above-noted factors that might predispose to treatment resistance, switching antidepressants, and augmentation with medication or psychotherapy. Other modalities, such as electroconvulsive therapy, vagal nerve stimulation, and repetitive transcranial magnetic stimulation, are also reviewed.

Electroconvulsive therapy in adolescents with the catatonia syndrome: efficacy and ethics

OBJECTIVES

In child and adolescent psychiatry, catatonia is infrequent, but it is one of the most severe syndromes, characterized by the coexistence of psychic and motor symptoms. In this report, we explore the therapeutic experience with electroconvulsive therapy (ECT) in adolescents with catatonia.

METHODS

We review the literature (1985-2009) to clarify issues related to the use of ECT in child and adolescent patients with catatonia.

RESULTS

Electroconvulsive therapy is used as second-line management after high-dose benzodiazepine trials. Electroconvulsive therapy is an effective, safe, and useful procedure in the treatment of catatonic youngsters as reported in 59 patients. Ethical issues regarding the use of ECT are analyzed and their implications briefly discussed in the light of general medical ethics.

CONCLUSIONS

Electroconvulsive therapy is a safe and effective treatment for catatonia in children and adolescents.

Moderate clinical improvement with maintenance ECT in a 17-year-old boy with intractable catatonic schizophrenia

The use of electro-convulsive therapy (ECT) in adolescents is controversial, and few studies have been conducted to assess its efficacy and safety in this population. We report the case of a 19-year-old boy who received two series of ECT, one at 15 and another at 16, for intractable catatonic schizophrenia. Since the age of 17, he has required treatment combining clozapine and maintenance ECT. The course showed a sustained moderate improvement. The treatment permitted the patient to regain some autonomy with moderate adverse effects. ECT remains an uncommon treatment in adolescents, and the current case supports the view that it should not be banned in young people.

The antidepressant effect of Gastrodia elata Bl. on the forced-swimming test in rats

Depression is a common psychiatric disorder with a high morbidity and mortality rate. The pharmacotherapy used in clinic today is not suitable for all patients and causes certain side-effects. Thus, looking for alternative treatments with antidepressant effect and minimal side-effect is important. Gastrodia elata Bl. is a famous Chinese traditional medicine used for centuries. The aim of this study is to test the antidepressant effect of Gastrodia elata Bl. extract (GE) using forced-swimming test (FST). Sprague-Dawley rats were assigned to control, GE, and fluoxetine groups, treated with 10 ml/kg bw (body weight) water, 1 g/kg bw of GE, and 15 mg/kg bw of fluoxetine, respectively. Those samples were administered by gavage to rats 23.5, 4.5 and 1 hour prior to the test session of FST. After FST, the animals were sacrificed and their brains were collected for monoamines analysis. The results indicated that the duration of immobility was significantly decreased in GE group compared to the control (p < 0.05). The concentration of serotonin (5-HT), 5-hydroxyindoleacetic acid (5-HIAA), and the ratio of 5-HIAA/5-HT in frontal cortex, amygdala, and hippocampus were not significantly different between GE and the control groups. However, administration of GE significantly increased the dopamine (DA) concentration (p < 0.05) and decreased the concentration of 3,4-dihydroxyphenylacetic acid (DOPAC) (p < 0.01) and DA turnover (p < 0.05) in striatum compared to the control. The results of this study show that Gastrodia elata Bl. extract modulates the turnover of DA in rats, and thus probably possesses antidepressant effect in rats.

Texas Children's Medication Algorithm Project: update from Texas Consensus Conference Panel on Medication Treatment of Childhood Major Depressive Disorder

OBJECTIVE

To revise and update consensus guidelines for medication treatment algorithms for childhood major depressive disorder based on new scientific evidence and expert clinical consensus when evidence is lacking.

METHOD

A consensus conference was held January 13-14, 2005, that included academic clinicians and researchers, practicing clinicians, administrators, consumers, and families. The focus was to review, update, and incorporate the most current data to inform and recommend specific pharmacological approaches and clinical guidance for treatment of major depressive disorder in children and adolescents.

RESULTS

Consensually agreed on medication algorithms for major depression (with and without psychosis) and comorbid attention-deficit disorders were updated. These revised algorithms also incorporated approaches to address issues of suicidality, aggression, and irritability. Stages 1, 2, and 3 of the algorithm consist of selective serotonin reuptake inhibitor and norepinephrine serotonin reuptake inhibitor medications whose use is supported by controlled, acute clinical trials and clinical experience. Recent studies provide support that selective serotonin reuptake inhibitors in addition to fluoxetine are still encouraged as first-line interventions. The need for additional assessments, precautions, and monitoring is emphasized, as well as continuation and maintenance treatment.

CONCLUSIONS

Evidence and expert clinical consensus support the use of selected antidepressants in the treatment of depression in youths. The use of the recommended antidepressant medications requires appropriate monitoring of suicidality and potential adverse effects and consideration of other evidence-based treatment alternatives such as cognitive behavioral therapies.

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.

ECT and The Youth: Catatonia in Context

Electroconvulsive therapy (ECT) has been in psychiatric practice for well over half a century, but it continues to incite controversy. However, it is regarded amongst psychiatrists as a safe and effective treatment and at times even a lifesaver. It offers a fairly swift but a time-limited response, opening up opportunities for initiation of more longer lasting treatments. The use of ECT in the youth is limited, and as such good studies are few and far between. The recent Practice Parameters by the American Academy of Child and Adolescent Psychiatry, specifically addressing ECT in adolescents, is indeed a welcome addition. Electrocovulsive therapy is as effective in the youth as it is in the adults, and the indications and contraindication are the same. The administration of ECT follows the same general principles in all age groups. One particular indication is of the use in catatonia, a motor syndrome that could occur with affective disorders, schizophrenia or medical conditions, in which it is considered to be extremely effective. The association between catatonia and autism and spectrum disorders has been noted, and in this situation, ECT is considered by some to be effective. Ethical considerations and that of capacity and informed consent are of paramount importance as are the human rights. Working in partnership with the parents/carers all the way is a must. The lack of information leaflets on ECT especially designed for young patients and their parents has to be rectified soon. Registers based on geographical health regions for those below the age of 18 will assist tremendously in epidemiological studies as well as pave the way toward more evidence-based studies that are essential.

Practice parameter for use of electroconvulsive therapy with adolescents

Electroconvulsive therapy (ECT) may be an effective treatment for adolescents with severe mood disorders and other Axis I psychiatric disorders when more conservative treatments have been unsuccessful. ECT may be considered when there is a lack of response to two or more trials of pharmacotherapy or when the severity of symptoms precludes waiting for a response to pharmacological treatment. The literature on ECT in adolescents, including studies and case reports, was reviewed and then integrated into clinically relevant guidelines for practitioners. Mood disorders have a high rate of response to ECT (75%-100%), whereas psychotic disorders have a lower response rate (50%-60%). Consent of the adolescent's legal guardian is mandatory, and the patient's consent or assent should be obtained. State legal guidelines and institutional guidelines must be followed. ECT techniques associated with the fewest adverse effects and greatest efficacy should be used. The presence of comorbid psychiatric disorder is not a contraindication. Systematic pretreatment and posttreatment evaluation, including symptom and cognitive assessment, is recommended.

A practical guide to using ratings of depression and anxiety in child psychiatric practice

The objective of this paper is to provide pragmatic information on commonly used rating scales of depression and anxiety disorders with established psychometric properties. A comprehensive Medline search on the rating scales of depression and anxiety was conducted. Relevant research findings were further synthesized where possible, with the information on clinical use of the scales from manuals. Research findings replicating original studies, strengths, weaknesses, and scoring information were summarized for each scale, and psychometric properties were tabulated. Several rating scales are available for screening, determining the severity, as well as estimating treatment effects in depression and anxiety. It is prudent to use more than two scales, especially a combination of self-rating scale and a clinician rating scale. It is recommended that the depression and anxiety scales are used in concert to aid in differentiating these two disorders. Several new and improved scales are available, although they await further replication.

Somatic treatment for depressive illnesses in children and adolescents

Numerous somatic interventions have been studied as potential treatments of depressive disorders in children and adolescents. These include antidepressant medications, light therapy, electro-convulsive therapy, and alternative therapies. The available evidence suggests that several somatic interventions hold promise as potentially safe and effective treatments for depressed youths; however, there is still much to be learned about these interventions. This article reviews what is known and what needs to be learned about the somatic treatment of pediatric depression.

Failure of Repeated Electroconvulsive Shock Treatment on 5-HT4-Receptor-Mediated Depolarization Due To Protein Kinase A System in Young Rat Hippocampal CA1 Neurons

We previously demonstrated that repeated electroconvulsive shock (ECS) treatment enhanced serotonin (5-HT)(1A)- and 5-HT(3)-receptor-mediated responses in hippocampal CA1 pyramidal neurons. The electrophysiological studies were performed to elucidate the effects of ECS treatment on depolarization, which was an additional response induced by 5-HT, and the second messenger system involved in this depolarization of hippocampal CA1 neurons. Both application of 5-HT (100 microM) induced depolarization of the membrane potential in the presence of 5-HT(1A)-receptor antagonists. This depolarization was mimicked by 5-HT(4)-receptor agonists, RS 67506 (1-30 microM) and RS 67333 (0.1-30 microM), in a concentration-dependent manner. 5-HT- and RS 67333-induced depolarization was attenuated by concomitant application of RS 39604, a 5-HT(4)-receptor antagonist. H-89, a protein kinase A (PKA) inhibitor, inhibited 5-HT-, RS 67506-, and RS 67333-induced depolarizations, while forskolin (10 microM), an activator of adenylate cyclase, induced depolarization. Furthermore, RS 67333-induced depolarization was not significantly different between hippocampal slices prepared from rats administered ECS once a day for 14 days and those from sham-treated rats. These findings suggest that 5-HT(4)-receptor-mediated depolarization is caused via the cAMP-PKA system. In addition, repeated ECS-treatment did not modify 5-HT(4)-receptor functions in contrast to 5-HT(1A)- and 5-HT(3)-receptor functions.

Tratamiento electroconvulsivo en niños y adolescentes

It is well-known that electroconvulsive therapy (ECT) is a safe and effective treatment for some mental disorders in adults. However, its use in children and adolescents is still the cause of some fears which may not be justified. The aim of this article is to clarify and to present the state of this question by reviewing the literature about ECT in children and adolescents, with emphasis on efficacy, indications, adverse effects and limitations. Results from studies in this population group show similar safety and efficacy data as those observed in adults. There exists a misinformation about the ECT technique among child psychologists and psychiatrists. Large follow-up studies are needed.

How fixed are child psychiatrists' views about ECT in the young?

The experience, knowledge, and attitudes of Australian and New Zealand child psychiatrists in relation to ECT in the young were surveyed in 2000 to ascertain whether their views had changed since a similar survey was conducted in 1996. Fifty-four percent (n = 129) of the original sample answered a mailed questionnaire. Psychiatrists in 2000 had greater self-rated level of knowledge on the subject and were less likely to base that knowledge on adult ECT data. Psychiatrists in 2000 were also more likely than in 1996 to approve the use of ECT in adolescents. The finding that the views of child psychiatrists can change is reassuring, given emerging data showing ECT in young persons to be an effective and safe treatment, and the requirement in various countries that child psychiatrists participate in the decision to administer the treatment. It is possible that a number of publications and presentations on the topic after the first survey contributed to the change in views. Nevertheless, there remain gaps in child psychiatrists' knowledge about ECT in the young that need to be addressed. The study findings should not be over interpreted because of the reduced response rate in the follow-up survey.

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

OBJECTIVE

To investigate whether there were changes in the practice and outcome of electroconvulsive therapy (ECT) in adolescents in a whole population over a decade.

METHOD

All persons younger than 19 years who received ECT in the state of New South Wales, Australia, in the period from 1990 to 1999 were identified. Detailed information about diagnosis, treatment and outcome were then obtained.

RESULTS

Seventy-two patients aged 14-18 years underwent a total of 84 courses of ECT (1.53/100,000 adolescents were treated with ECT per year). In 1996 to 1999 compared with 1990 to 1995, there was an increase in ECT among females hospitalized involuntarily, EEG monitoring, stimulus dosing, bilateral ECT, and use of thiopentone. Overall, mood disorders derived most benefit from ECT while comorbid personality disorder predicted poorer short term outcome. Side effects were minor and transient.

CONCLUSIONS

The changes in ECT practice are consistent with changes in ECT practice generally over the survey period. The overall data on effectiveness and safety further support the treatment's use in young people.

Clinical relevance of electroconvulsive therapy (ECT) in adolescents with severe mood disorder: evidence from a follow-up study

Given the limited knowledge on the long-term outcome of adolescents who receive electroconvulsive therapy (ECT), the study aimed to follow-up adolescents treated with ECT for severe mood disorder. Eleven subjects treated during adolescence with bilateral ECT for psychotic depression (n = 6) or mania (n = 5), and ten psychiatric controls matched for sex, age, school level, and clinical diagnosis, completed at least 1 year after treatment a clinical and social evaluation. Mean duration between time of index episode and time of follow-up evaluation was 5.2 years (range 2-9 years). At follow-up: (1) all patients except two in the control group received a diagnosis of bipolar disorder. (2) Fifteen patients had had more than one episode of mood disorder. (3) The two groups did not differ in social functioning nor school achievement. (4) Impact on school achievement was related to the severity of the mood disorder rather than ECT treatment. The results suggest that adolescents given ECT for bipolar disorder, depressed or manic, do not differ in subsequent school and social functioning from carefully matched controls.

Ten-year review of rating scales. II: Scales for internalizing disorders

OBJECTIVE

This article, the second in the Journal's series of 10-year updates on rating scales, summarizes scales assessing internalizing disorders.

METHOD

The authors sampled articles on mood and anxiety disorders over the past 25 years, selected scales with multiple citations over many years, and reviewed their properties. Those with adequate psychometric properties, plus continued wide literature citations or a current special niche, are presented here.

RESULTS

Rating scales for depression were developed and/or examined in the 1980s. Despite generally strong properties, they lack clear construct validity. Most have parent-report forms that broaden their suitability with youths. Anxiety scales were developed bimodally. Those developed in the 1960s to 1970s were downward modifications of adult scales. They have been criticized for unclear constructs and unsuitability for youths. Newer scales developed in the 1990s have addressed these problems and have parent-report forms. However, their utility is still being determined.

CONCLUSIONS

Rating scales can reliably, validly, and efficiently measure youths' internalizing psychopathology. They have great utility in research, treatment planning, and accountability in practice. However, the user must define the goals of measurement, consider the construct the scale measures, and use the scale within its defined capabilities. The use of more than one scale for a task is recommended.

Electroconvulsive therapy in adolescents: similarities to and differences from adults

OBJECTIVE

Information on the indications, technique, and effectiveness of electroconvulsive therapy (ECT) in adolescent patients is scarce. The recommendations for the use of ECT in this age group are similar to those in adults. This study compares the experience with ECT in the two age groups in the same community psychiatric institution, which adheres to the accepted protocols for diagnosis and treatment.

METHOD

The files of 24 consecutive adolescent patients treated in an ECT unit located in the center of Israel in the years 1991-1995 were retrospectively examined, and the findings were compared with those in 33 adult patients who started their ECT course on the same day. The technique for applying ECT was essentially the same in the two age groups.

RESULTS

ECT was equally effective for adolescents and adults (58% in each group achieved remission). The main difference was the diagnosis for which patients were referred: most of the adolescents were in the "psychotic spectrum, whereas most of the adults were in the "affective spectrum."

CONCLUSIONS

The findings support the current medical recommendations for the use of ECT in adolescents. Possible explanations for the differences in diagnosis between the two age groups are discussed.

Electroconvulsive therapy in adolescents with mood disorder: patients' and parents' attitudes

The aim of the study was to assess retrospectively patients' and parents' experiences and attitudes towards the use of electroconvulsive therapy (ECT) in adolescence. The experiences of subjects (n=10) who were administered ECT in adolescence for a severe mood disorder and their parents (n=18) were assessed using a semi-structured interview after a mean of 4.5 years (range, 19 months to 9 years). Their attitudes were mostly positive and ECT was considered a helpful treatment. Concerns were frequently expressed, probably because ECT was not fully understood by the patients and their families. Most complaints were of transitory memory impairment. The parents were satisfied with the consent procedure, while all but one patient did not remember the consent procedure. We concluded that, despite negative views about ECT in public opinion, adolescent recipients and their parents shared overall positive attitudes towards the use of ECT in this age range.

Potentiation of 5-HT(3) receptor functions in the hippocampal CA1 region of rats following repeated electroconvulsive shock treatments

Modulation of serotonin (5-HT)(3)-receptor function by repeated electroconvulsive shock (ECS) treatment was investigated to elucidate the mechanism underlying the effectiveness of electroconvulsive therapy (ECT) which is clinically used for drug-resistant depression. ECS (100 V, 1 s) was applied once a day for 14 days via an electrode placed on the ears of rats (ECS group). For controls, rats were handled similar to the ECS-treated group except for the stimulation. Hippocampal slices (thickness, 450 microm) were prepared 24 h after the final ECS treatment when rats were 5-6 weeks old. Intracellular recordings were made from the neurons in the CA1 pyramidal cell layer. Activation of 5-HT(3) receptors increased spontaneous postsynaptic potentials (sPSP). Increased sPSP was mainly mediated by GABA. The 5-HT(3) receptor mediated increase in sPSP was potentiated in the ECS group compared with the control group. These findings suggest that the 5-HT(3) receptor function is potentiated by repeated ECS.

Electroconvulsive therapy for minors: experiences and attitudes of child psychiatrists and psychologists

OBJECTIVE

To estimate knowledge, experience, and attitudes towards the use of electroconvulsive treatment in minors (patients < 18 years of age), among child and adolescent psychiatrists and psychologists.

METHOD

1,600 questionnaires were mailed to a group of child and adolescent psychiatrists and psychologists.

RESULT

There were 625 (39%) respondents. 329 (53.8%) of the respondents stated that they possessed minimal knowledge about the use of ECT in children and adolescents. Lack of confidence in providing a second opinion was common and reported by 75%. Compared with those with minimal knowledge, respondents with advanced knowledge reported a higher perception of safety and efficacy. The majority (70%) of the respondents regarded ECT as a treatment of last resort.

CONCLUSION

Many child and adolescent psychiatrists and psychologists have very little knowledge, training, or experience in this treatment. They seem to be ill equipped to appropriately consider or advise patients and families about ECT. Clinical and research implications of these findings are discussed.

Somatic treatment of psychotic depression: review and recommendations for practice

The diagnosis, classification, and course of psychotic major depression (PMD) is considered with regard to its status as a distinct syndrome. Several factors, especially biological markers, suggest, although as yet do not confirm, that PMD is distinct from nonpsychotic major depression (NPMD), particularly for the purposes of treatment. This article provides a critical review of somatic treatments for PMD, with attention to problems of inadequate treatment, as well as underused and more recently introduced treatments. The somatic treatment options reviewed include (1) combined antidepressant (AD) and antipsychotic (AP) therapy with tricyclic antidepressants (TCAs) and typical APs; (2) electroconvulsive therapy (ECT); (3) amoxapine; (4) selective serotonin reuptake inhibitors (SSRIs), alone and in combination; (5) several atypical APs, alone and in combination; (6) mood stabilizers and anticonvulsants; and (7) some experimental treatments and surgery. A comprehensive treatment algorithm (heuristic) is presented, which draws on some previous guidelines and the critical review. This heuristic is conservative in its aims, but forward-looking in its recommendations. The status of the TCA plus typical AP regime is challenged as the default first-line treatment, and preferable alternatives are discussed. ECT has been shown to be at least as effective in short-term treatment and should be considered more frequently, especially in severe presentations and as a maintenance treatment. Some single compounds should be considered as first-line monotherapies in less severe cases. For cases in which combined AD+AP regimes are instituted, SSRIs and atypical APs should be used before older classes of drugs are considered. These recommendations aim to minimize the number of treatments used and unwanted effects experienced.

Evaluation of newer treatment interventions for psychotic depression

Psychotic depression is characterized by greater severity, higher rate of recurrence, greater incapacitation, more frequent hospitalization, and longer episodes than nonpsychotic depression. The use of combined tricyclic antidepressants (TCAs) and neuroleptic therapy, as well as electroconvulsive therapy, has proven effectiveness in the treatment of psychotic depression. Although it is limited, evidence for efficacy of selective serontonin reuptake inhibitors both alone and in combination with antipsychotics in psychotic depression suggests that these strategies may provide a desirable alternative to the traditional TCA- neuroleptic therapy. These treatments, in addition to the continual introduction of new psychotropic agents suggest that the prospect of future research in this area is promising.

The Texas Children's Medication Algorithm Project: report of the Texas Consensus Conference Panel on Medication Treatment of Childhood Major Depressive Disorder

OBJECTIVES

To develop consensus guidelines for medication treatment algorithms for childhood major depressive disorder (MDD) based on scientific evidence and clinical opinion when science is lacking. The ultimate goal of this approach is to synthesize research and clinical experience for the practitioner and to increase the uniformity of preferred treatment for childhood MDD. A final goal is to develop an approach that can be tested as to whether it improves clinical outcomes for children and adolescents with MDD.

METHOD

A consensus conference was held. Participants included academic clinicians and researchers, practicing clinicians, administrators, consumers, and families. The focus was to review and use clinical evidence to recommend specific pharmacological approaches for treatment of MDD in children and adolescents. After a series of presentations of current research evidence and panel discussion, the consensus panel met, agreed on assumptions, and drafted the algorithms. The process initially addressed strategies of treatment and then tactics to implement the strategies.

RESULTS

Consensually agreed-upon algorithms for major depressions (with and without psychosis) and comorbid attention deficit disorders were developed. Treatment strategies emphasized the use of selective serotonin reuptake inhibitors. The algorithm consists of systematic strategies for treatment interventions and recommended tactics for implementation of the strategies, including medication augmentation and medication combinations. Participants recommended prospective evaluation of the algorithms in various public sector settings, and many volunteered as sites for such an evaluation.

CONCLUSIONS

Using scientific and clinical experience, consensus-derived algorithms for children and adolescents with MDD can be developed.

Bipolar disorder in children and adolescents

Bipolar disorder is an affective or mood disorder that affects children and adolescents as well as adults. Originally thought to be rare in childhood, this disorder is now diagnosed even in the prepubertal age group. With pediatricians providing health care for the majority of children and adolescents, these physicians will see the children early in their presentation with affective disorder. This review focuses on the early recognition of children with bipolar disorder or children who are at increased risk of developing mania. Early recognition can lead to early treatment and reduce both short- and long-term morbidity and mortality. This review covers the definition, epidemiology, presentation and differential diagnosis, comorbid diagnoses, precipitants, risk factors, treatment, and outcome.

Electroconvulsive therapy in adolescents: experience, knowledge, and attitudes of recipients

OBJECTIVE

To ascertain the experience, knowledge, and attitudes regarding electroconvulsive therapy (ECT) of persons who received the treatment in adolescence.

METHOD

A 53-item survey was administered by telephone to persons who received ECT before the age of 19 years in the Australian state of New South Wales between 1990 and 1998.

RESULTS

Twenty-six patients were interviewed. Experiences and opinions about ECT were generally positive. Fifty percent stated ECT had been helpful. Approximately three quarters believed their illness was worse than either ECT or pharmacotherapy. Frequencies of recalled side effects with ECT and medication were similar. Some patients perceived deficiencies in the consent process. A slight majority had attempted to conceal the history of ECT treatment. The vast majority considered ECT a legitimate treatment and, if medically indicated, would have ECT again and would recommend it to others.

CONCLUSIONS

The findings are consistent with and complement evidence showing ECT to be an effective and safe treatment for seriously ill adolescents. The mostly favorable experiences and attitudes reported by interviewees will be reassuring to adolescent patients, their families, and treating health professionals when ECT is being considered.
