A Case of Catatonia in a 37-Month-Old Child With MOG-Antibody–Positive Acute Disseminated Encephalomyelitis

In this Letter to the Editor, we examine a case of catatonia in a 37-month-old child with myelin oligodendrocyte glycoprotein (MOG) antibody–positive acute disseminated encephalomyelitis (ADEM). To our knowledge, this is one of the youngest cases of non–drug-related catatonia reported in the literature.1,2 We will discuss how this patient’s symptoms of catatonia responded to pharmacologic interventions and the need to screen young children for catatonic symptoms, given the high rate of morbidity and mortality associated with the condition.3 The authors used CAse REports (CARE) guidelines in writing this report (Supplement 1). The patient’s family gave written consent for the publication of this article.
