The Differential Diagnosis and Treatment of Catatonia in Children and Adolescents

Hypokinetic catatonia in an adolescent with psychotic and mood disorders: A case report

OBJECTIVE

Pediatric catatonia case report and literature review.

METHODS

Retrospective chart review and provider consultation.

RESULTS

A case of pediatric catatonia is described in the setting of mood and psychotic disorders. Treatment course and outcomes are considered in the context of supporting literature review and discussion.

CONCLUSIONS

Pediatric catatonia is a debilitating and at times life threatening condition. Pediatric catatonia is historically underdiagnosed and its clinical presentation may differ from more common adult cases of catatonia. Correct identification, acute treatment, and long-term management is key to optimizing prognosis and patient outcomes.

Safe Use of Memantine in a Pediatric Patient With Catatonia

Pediatric catatonia is a complex neuropsychiatric syndrome. Benzodiazepines are standard first-line pharmacotherapy. When benzodiazepines do not provide relief of symptoms, electroconvulsive therapy (ECT) is the most proven effective therapy. However, the use of NMDA antagonists (amantadine and memantine) has been reported effective in adult patients as adjuncts and may provide an alternative treatment modality when ECT is not readily accessible. To the author's knowledge there are no prior case reports of memantine used in pediatric catatonia. This case demonstrates the safe use of memantine as an adjunctive agent in an adolescent with catatonia.

Catatonia: Back to the future of the neuropsychiatric syndrome

Catatonia is an undertreated and underdiagnosed neuropsychiatric syndrome whose prognosis is benign if treated early, thus avoiding possible complications and compromising the health of patients. The latest epidemiological studies indicate a prevalence of catatonia of 9.2%, being frequent in medical pathologies (especially neurological ones), as well as in psychiatric pathologies. The use of validated scales is recommended for its diagnosis, to be able to measure the severity and response to treatment. Once catatonia has been identified, it is necessary to perform a protocolized diagnostic study of the underlying aetiology («Catatonia Workup»). Treatment of choice is benzodiazepines and electroconvulsive therapy. In recent years, new therapeutic alternatives such as non-invasive transcranial magnetic stimulation have emerged. In this review we propose several initiatives to promote the dissemination and knowledge of catatonia in the clinical setting.

A diagnostic challenge in an unresponsive refugee child improving with neurosurgery-a case report

An unresponsive paediatric patient may present a diagnostic challenge for health professionals, as rapid identification of the cause is needed to provide proper interventions. The following report details a challenging diagnosis of unresponsiveness in a refugee child. In the migratory context, observed unresponsiveness states are frequently attributed to psychologic factors, and overlapping psychiatric classifications (resignation syndrome, functional coma and catatonia) are common. Our patient fell into an unresponsive state for 6 months after witnessing a traumatic event. Diagnostic workup for multiple medical comorbidities led to surgical intervention for tethered cord syndrome. Shortly after that, the patient’s responsiveness improved, putting to question her condition’s underlying cause. This case highlights the need for a biopsychosocial approach in such cases, reflected in thorough clinical examination and diagnostic investigations. A multidisciplinary perspective and expertise proved crucial and may help in the rehabilitation of children in similar situations.

Treatment of a Complex Case of Catatonia and Conversion Features With Electroconvulsive Therapy in a 14-Year-Old Male

Background: Pediatric catatonia is a rare and poorly understood phenomenon. The majority of reported cases have a psychiatric etiology. Because of the heterogeneous presentation and treatment issues unique to the pediatric population, identification and management can be challenging. Additionally, few definitive guidelines or practice parameters are available for pediatric patients. The first-line treatment for catatonia is pharmacologic, and when treatment fails or is inadequate, electroconvulsive therapy (ECT) has been shown to be safe and effective. Case Report: A previously healthy, 14-year-old male presented with acute onset of catatonia that resolved at 4 weeks after a short course of ECT with adjunctive lorazepam and risperidone. An interesting feature of this case was the resolution of autonomic symptoms and the emergence of conversion features. The resolution of the catatonia (negativism, mutism, and withdrawal) made it possible for the team to identify a thought disorder and initiate appropriate pharmacologic treatment for the precipitating etiology. Conclusion: ECT was a safe and effective treatment for the resolution of catatonia symptoms in this patient. Conversion and catatonia features may exist on a continuum.

Autism, Psychosis, or Both? Unraveling Complex Patient Presentations

Autism spectrum disorders (ASDs) and schizophrenia spectrum disorders co-occur at elevated rates. Although these conditions are diagnostically distinct, they share multiple clinical features and genetic risk factors. This article describes the epidemiologic features and clinical manifestations of psychosis in individuals with ASDs, while also discussing shared genetic risk factors and affected brain regions. Components of a diagnostic assessment, including a thorough developmental, behavioral, medical, and psychiatric history, will be reviewed. The authors highlight the manifestations of catatonia in this population and note the shared features between catatonia and ASDs. Finally, treatment approaches and areas for future study are suggested.

Catatonia in Down syndrome: systematic approach to diagnosis, treatment and outcome assessment based on a case series of seven patients

OBJECTIVE

The goal is to expand our knowledge of catatonia occurring in adolescents and young adults with Down syndrome (DS) by describing the first prospective, consecutive, well-characterized cohort of seven young people with DS diagnosed with catatonia and treated between 2013 and 2018, and to assess each patient's treatment responses. Longitudinal assessment of each patient's response to treatment is intended to provide clinicians and psychiatrists a firm foundation from which assess treatment efficacy.

STUDY DESIGN

Young adults with Down syndrome were consecutively enrolled in the study as they were diagnosed with catatonia. A comprehensive data set included medical, laboratory, developmental, demographic, family, social and genetic data, including query into disorders for which individuals with DS are at risk. Catatonia was diagnosed based on an unequivocal history of regression, positive Bush-Francis Catatonia Rating Scale and positive response to intravenous lorazepam. Patients' longitudinal progress was monitored using the Catatonia Impact Scale (CIS) developed for this purpose.

RESULTS

Seven consecutive DS patients, who presented with unequivocal regression were diagnosed with catatonia and treated for 2.7-6 years using standard-of-care therapies; primarily GABA agonist, lorazepam, electroconvulsive therapy (ECT) and glutamate antagonists (dextromethorphan/quinidine, memantine, minocycline). Responses to each treatment modality were assessed at clinic visits and through weekly electronic CIS reports.

CONCLUSION

Seven young adults with DS were diagnosed with catatonia; all responded to Lorazepam and/or ECT therapy with good to very good results. Though ECT most dramatically returned patients to baseline, symptoms often returned requiring additional ECT. Dextromethorphan/quinidine, not used until mid-2017, appeared to reduce the reoccurrence of symptoms following ECT. Though all seven patients improved significantly, each continues to require some form of treatment to maintain a good level of functioning. Findings of a significant number of autoimmune disorders and laboratory markers of immune activation in this population may guide new diagnostic and treatment opportunities.

Focused Medical Assessment of Pediatric Behavioral Emergencies

There is no uniformly accepted standard of care for medical clearance of pediatric patients with psychiatric complaints. Emerging data argue for a thorough history and physical examination and against routine laboratory testing. The differential diagnosis of patients presenting with psychiatric health complaints is extensive and includes both medical and psychiatric disorders. Providers should remain mindful of anchoring or diagnosis momentum bias when caring for these patients, especially patients with a psychiatric history.

Pediatric Catatonia: A Case Series-Based Review of Presentation, Evaluation, and Management

BACKGROUND

Pediatric catatonia is believed to be a rare condition, but challenges in recognition and variability in presentation may lead to underdiagnosis. Early identification and effective treatment of pediatric catatonia is critical given the significant morbidity and mortality associated with the condition. Given the widespread shortage of child and adolescent psychiatrists, at times consultation-liaison (C-L) psychiatrists without child training may be the frontline specialty providers asked to guide treatment of these pediatric patients.

OBJECTIVE

To review the literature on pediatric catatonia using clinical cases to illustrate unique aspects of its presentation, evaluation, and management.

METHODS

We describe the presentation and management of 6 adolescents with catatonia on an inpatient pediatric service at a general hospital and use these cases as a focal point for a review of the literature.

CONCLUSION

Pediatric catatonia is a potentially lethal disease entity that can be effectively treated if accurately identified early in its course. Psychiatrists working in a C-L setting may encounter this syndrome and should be aware of its presentation, evaluation, and management.
