Abstract

Catatonia is a neuropsychiatric syndrome that is an increasingly recognized cause of acute behavioural changes in children and adolescents with neurodevelopmental disorders (NDD). Literature suggests that catatonia can present differently in this population and can be missed due to diagnostic overshadowing. Catatonia is a treatable condition, and management strategies in children with NDD include benzodiazepines and electroconvulsive therapy (ECT). Untreated, it can cause significant morbidity including severe medical complications, and therefore timely recognition and management of catatonia in children and adolescents with NDD is essential. In this case series, we present three cases of children ages 7, 14, and 10, with diagnoses of autism spectrum disorder, Down syndrome, and Prader-Willi syndrome, respectively. All were admitted to a pediatric inpatient unit for acute behavioural regression. Each had symptoms consistent with catatonia, resulting in trials of benzodiazepine therapy with inadequate response, and were then treated with bilateral ECT. In all cases, marked improvement was noted after ECT, with no apparent adverse effects. The cases are used to highlight the nuances of diagnosis and management of catatonia in children and adolescents with NDD. This includes insights on how presentations of catatonia may differ in this population, challenges with the use of available diagnostic tools, and how these patients may respond differently to recommended treatments such as benzodiazepines. The case series aims to increase clinicians' awareness of pediatric catatonia when children and adolescents with NDD present with acute behavioural changes, and to encourage consideration of the full spectrum of treatments, including bilateral ECT.
