Unmasking the Enigma: A Case Report of Catatonia Unveiled As Munchausen by Proxy.

Catatonia is a behavioral syndrome characterized by a variety of symptoms such as mutism, stupor, rigidity, negativism, and verbigeration. It can be caused by various psychiatric and general medical conditions. While the diagnosis in the pediatric population is relatively uncommon, emerging literature supports a higher prevalence of catatonia in children. We present a 12-year-old girl with a complex medical and psychosocial history, including a functional neurological disorder and concerns for child abuse and Munchausen syndrome by proxy imposed by her mother. The patient was initially admitted for medical management of vomiting and refusal to eat. Child psychiatry was consulted for further assessment and noted multiple catatonic symptoms with a Busch-Francis catatonia rating scale (BFCRS) score of 22. A subsequent 1 mg IV lorazepam challenge test showed improvement in the patient's symptoms with a repeat BFCRS score of 10. This case supports emerging literature suggesting a higher prevalence of catatonia in children and the importance of recognizing this syndrome and its wide array of underlying causes.
