Maintenance Electroconvulsive Therapy Is an Essential Medical Treatment for Patients With Catatonia: A COVID-19 Related Experience

Maintenance Electroconvulsive Therapy in Catatonia: Clinical Profiles From a Case Series

OBJECTIVES

This study aims to conduct a descriptive analysis of the clinical features and treatment responses in 6 patients with catatonia who received maintenance electroconvulsive therapy (ECT).

METHODS

Our study included all patients who underwent maintenance ECT (mECT) at the Hospital Clínic de Barcelona between September 2020 and September 2022 following a catatonic episode.

RESULTS

The study cohort comprised 5 patients with schizophrenia and 1 patient with major depressive disorder. Among patients with schizophrenia, the first catatonic episode occurred several years after their initial paranoid psychotic episode, whereas the patient with depression experienced a rapid progression from the first depressive episode to catatonia. After acute ECT, 4 patients achieved complete symptomatic remission, 1 patient exhibited a partial response, and another maintained a severe catatonic state. Maintenance ECT was indicated because of the high risk of severe relapses. The mean frequency of mECT sessions was 9.83 (SD, 5.60) days. Notably, 66.67% of the patients were concurrently receiving clozapine as part of their pharmacological treatment. Among patients with schizophrenia, mECT sessions could not be extended beyond 7 to 10 days, whereas the depressed patient could space ECT sessions up to 21 days without experiencing a relapse.

CONCLUSIONS

Maintenance ECT proves to be a safe and well-tolerated strategy for preventing relapses in severe catatonic patients who have previously stabilized with acute ECT. Further research is needed to develop clinical guidelines that define optimal application strategies for mECT in catatonia.

[Electroconvulsive therapy in people with intellectual disability]

Electroconvulsive therapy (ECT) is a highly effective treatment option for severe mental illness. Although people with intellectual disability (ID) have similar prevalence rates of mental disorders in comparison to the general population their access to ECT remains challenging. A systematic literature review was carried out on treatment with ECT in patients with ID and a case report on a patient with ID who underwent ECT is presented, to highlight a typical clinical routine. A total of 100 articles with 208 different case reports were retrieved. In summary, the results underline the effectiveness of ECT in people with ID, with side effects comparable to those in the general population. The ECT is effective in the treatment of severe affective and psychotic disorders and particularly in people with catatonia. The use of ECT can improve the patient's mental health and quality of life and is often a life-saving treatment option. The prophylaxis of relapses should be included as early as possible in the planning process. Providing an easy access to ECT treatment for people with ID is corroborated by its effectiveness and is in line with the right to equal treatment in accordance with article 25 of the United Nations Convention on the Rights of Persons with Disabilities.

Catatonia and ECT across the lifespan

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

Factors Associated With Utilization of Electroconvulsive Therapy During Psychiatric Hospitalization Among Children and Adolescents in China

PURPOSE

Based on a nationally representative sample in China, we examined the demographic and clinical correlates of utilization of electroconvulsive therapy (ECT) in child and adolescent (C/A) patients younger than 18 years during psychiatric hospitalization.

METHODS

As part of a national survey, 41 provincial tertiary psychiatric hospitals in mainland China were selected. Data from 196 C/A patients who were discharged from these psychiatric hospitals from March 19 to 31, 2019, were retrieved and analyzed.

RESULTS

(1) The overall rate of ECT among C/A patients during psychiatric hospitalization was 15.6% (n = 30). (2) Between ECT and non-ECT groups, significant differences were found in sex, age, length of stay, Global Assessment of Functioning at admission, treatment outcome, and self-injurious behavior during hospitalization, and the ratio of marked improvement on discharge. (3) Multiple logistic regression analysis revealed that ECT use was independently and positively associated with an older age, male sex, lower Global Assessment of Functioning, and self-injurious behavior during hospitalization.

CONCLUSIONS

The frequency of ECT use was relatively frequent in C/A patients during psychiatric hospitalization in our nationally representative sample in China. Developing more specific and operational criteria for the use of ECT for C/A patients is needed to provide guidance for the optimal use of ECT in this patient population.

Evidence-based consensus guidelines for the management of catatonia: Recommendations from the British Association for Psychopharmacology

The British Association for Psychopharmacology developed an evidence-based consensus guideline on the management of catatonia. A group of international experts from a wide range of disciplines was assembled. Evidence was gathered from existing systematic reviews and the primary literature. Recommendations were made on the basis of this evidence and were graded in terms of their strength. The guideline initially covers the diagnosis, aetiology, clinical features and descriptive epidemiology of catatonia. Clinical assessments, including history, physical examination and investigations are then considered. Treatment with benzodiazepines, electroconvulsive therapy and other pharmacological and neuromodulatory therapies is covered. Special regard is given to periodic catatonia, malignant catatonia, neuroleptic malignant syndrome and antipsychotic-induced catatonia. There is attention to the needs of particular groups, namely children and adolescents, older adults, women in the perinatal period, people with autism spectrum disorder and those with certain medical conditions. Clinical trials were uncommon, and the recommendations in this guideline are mainly informed by small observational studies, case series and case reports, which highlights the need for randomised controlled trials and prospective cohort studies in this area.
