Catatonia and Maintenance Electroconvulsive Therapy in a 15-Year-Old Patient With MED13L Haploinsufficiency Syndrome in the Context of Epilepsy Diathesis.

This is the first report of pediatric catatonia syndrome in MED13L haploinsufficiency syndrome. This report describes unique challenges in diagnosis and management of catatonia in rare genetic conditions. The case also illustrates the use of electroconvulsive therapy in patients with epilepsy, epileptic encephalopathy, or other epileptic diathesis and the clinical conundrum in determining the course of maintenance electroconvulsive therapy.

Catatonia in Preadolescent Children.

Objective: The aim of the study is to describe prepubescent catatonia in very young children, which is poorly documented in the current literature and, as a result, overlooked in medical settings.

Methods: We examined a convenience sample of 10 patients at an academic center who were younger than 12 years and met criteria for catatonia. After institutional review board approval, we extracted from the electronic medical records demographic and diagnostic information, comorbidity, developmental history, and laboratory testing.
