Use of electroconvulsive therapy in the treatment of catatonia

Recurrent Catatonia due to Episodic Obsessive-Compulsive Disorder

Background. Catatonia is regarded as a diverse type of motor dysregulation syndrome that includes mutism, immobility, catalepsy, negativism, stereotypies, and echo phenomena. Catatonia is known to coexist with a wide range of physical and mental health conditions, including mood disorders, schizophrenia, autoimmune disorders, and metabolic abnormalities. Albeit, the association between obsessive-compulsive disorder (OCD) and catatonia is underreported, and mechanisms are not well elucidated. Study. In this study, we present a case of a 36-year-old woman who developed episodes of catatonia during the course of her obsessive-compulsive disorder (OCD). Success rates have been recorded with both benzodiazepines and electroconvulsive therapy (ECT). Gauging the severity of her symptoms and poor drug compliance, the patient was opted for and successfully treated with ECT. She was also educated about OCD through a series of therapy sessions and exposure and response prevention (ERP) principles. She was maintained on ERP and adjunctive clonazepam upon discharge. On subsequent follow-ups, the patient seemed to be doing well and was eager to begin her job again. Conclusion. Our study shows a possible link between OCD and catatonia. Additionally, robust studies are needed in order to determine the pathophysiology of catatonia and the mechanism of ECT so that more beneficial therapeutics can be developed. A combination of ECT and antidepressants with ERP therapy for recurrent catatonia with OCD could be effective as a therapeutic modality.

The Use of Lorazepam and Electroconvulsive Therapy in the Treatment of Catatonia: Treatment Characteristics and Outcomes in 60 Patients

OBJECTIVES

Lorazepam and electroconvulsive therapy (ECT) are effective treatments for catatonia. However, systematic data on these treatments in catatonia are limited. In the present study, we aimed to investigate the clinical and treatment-related characteristics of patients with catatonia who underwent lorazepam and/or ECT.

METHODS

Between January 2012 and December 2016, we received 60 patients with catatonia hospitalized in the Gaziantep University Faculty of Medicine Clinic of Psychiatry. Lorazepam and/or ECT were used in the patients' treatment schedule. Treatment results were evaluated using the Bush-Francis Catatonia Rating Scale and Clinical Global Impression-Improvement.

RESULTS

Thirty-five patients (58.3%) in the sample were in their first catatonic episode. The most common comorbidity was mood disorder (n = 34, 56.7%), whereas the most frequent catatonic sign was mutism (n = 43, 71.7%). Moreover, 31 patients (51.7%) had some form of medical comorbidity. Cerebral abnormalities were detected in computed tomography/magnetic resonance imaging in 22 patients (36.7%). Furthermore, 95% of the patients (n = 57) fully recovered after administration of the treatment.

CONCLUSIONS

Lorazepam is a reasonable initial choice in the treatment of catatonia, with rapid consideration for ECT if there is no rapid response to lorazepam.
