Use of En-Bloc Multiple Monitored Electroconvulsive Therapy in Benzodiazepine Refractory Malignant Catatonia.

ABSTRACT: We report a case of an adolescent female experiencing benzodiazepine and single-stimulation electroconvulsive (ECT)-refractory malignant catatonia, who improved with the use multiple monitored ECT (mmECT). Per the 2001 American Psychiatric Association guidelines, mmECT should be considered only in cases of intractable seizures or neuroleptic malignant syndrome. Since 2001, neuroleptic malignant syndrome and malignant catatonia have been described as occurring along the same spectrum of illness. Therefore, given the life-threatening nature of her condition, as well as the brief seizure duration she experienced from single-stimulation ECT, the patient was treated with en-bloc and 2-stimulation mmECT. The patient demonstrated a significant improvement in response to this treatment, with her Bush-Francis Catatonia Rating Scale score decreasing by 89%. At 2-year follow-up in an outpatient neurodevelopmental catatonia clinic, the patient has been able to return to school in her previous advanced placement classes and has not required maintenance ECT.

Manifestation of Catatonia in an Adolescent With 22q11.2 Syndrome.

In this Letter to the Editor, we present a case of 22q11.2 deletion syndrome that was diagnosed in an adolescent girl after the onset of acute catatonic symptoms. We discuss the challenges in diagnosing catatonia in children and patients with comorbid neurodevelopmental disorders (NDDs), especially in the setting of recent traumatic exposure. We then review treatment strategies in this patient population and conclude with our recommendations regarding genetic workup in acute catatonia. The patient and guardians have reviewed this article and provided informed consent for its publication. In addition, the authors used the CARE guidelines and checklist in writing this report (Supplement 1, available online).

Another Option for Aggression and Self-Injury, Alternative Benzodiazepines for Catatonia in Profound Autism.

Introduction: Individuals with profound autism often present for inpatient care due to aggression. Diagnostic and treatment options are limited. Agitated catatonia is a treatable comorbidity in autism, which should be considered in cases of aggression. Preliminary data report high clinical response rates of catatonia in autism when treated with electroconvulsive therapy (ECT), with poor response to lorazepam. However, access to ECT is often limited, especially in pediatric populations. Methods: We conducted a retrospective chart review to identify cases of hyperactive catatonia with partial response to lorazepam in profoundly autistic children presenting to the pediatric medical hospital. Five cases were identified, all of whom were followed by the child and adolescent psychiatry consult-liaison service during admission and treated without the use of ECT. Data from the medical record were obtained after institutional review board (IRB) approval including the following: (1) treatment course, (2) Bush-Francis Catatonia Rating Scale (BFCRS) scores, and (3) Kanner Catatonia Rating Scale (KCRS) severity scores. The Clinical Global Impressions-Improvement (CGI-I) Scale was applied retrospectively to each case. Results: All five patients demonstrated clinically significant improvements. The average CGI-I score was 1.2. The average percentage reduction in the BFCRS and KCRS severity scores was 63% and 59%, respectively. Two of five patients were first stabilized with infusions midazolam and dexmedetomidine due to the symptom severity and then transitioned to long-acting oral benzodiazepines. Overall, four of five patients were stabilized with oral clonazepam and one of five with oral diazepam. Notably, four of five patients experienced an acute worsening of aggression, self-injury, and other catatonic symptoms with escalating dosages of antipsychotic treatment, which occurred before inpatient admission. All patients experienced resolution of physical aggression toward self and/or others, experienced improvement in their communicative abilities, and were able to return home or enter residential level of care upon discharge. Conclusions: Given the limited availability of ECT and the unclear utility of lorazepam for hyperactive catatonia in autism, the use of long-acting benzodiazepines and/or midazolam infusion may offer a safe and readily available treatment alternative.

Morbidity Due to Disparity in Pediatric Electroconvulsive Therapy.

Dr. Miller and colleagues recently submitted a Letter to the Editor discussing current state laws that result in disparity of electroconvulsive therapy (ECT) availability.1 In this current letter, we present a case of treatment-resistant childhood-onset schizophrenia (COS), with morbidity due to limited access to ECT. The patient and his family presented from Kentucky to Tennessee, despite less legislative regulation in the former. The patient's family provided informed consent for this report to be published.
