Objectives: In patients with catatonia, it has been discovered that benzodiazepines (BZD) have a remarkable impact. However, there is not much evidence reflecting the long-term treatment with only BZDs before considering electroconvulsive therapy. Materials and Methods: One-year retrospective data of patients obtained from the health management information system (HMIS) portal and records of the department of psychiatry with the diagnosis of catatonia. This data was then analyzed for adequate history, presenting complaints, treatment taken, substance use, and was organized into five groups depending on the primary diagnosis as per the Diagnostic and Statistical Manual of Mental. The scores of Bush-Francis Catatonia Rating Scales of day 1 and subsequent follow-ups were secured. Categorical variables were analyzed with the Chi-squared test. The response overtime for all the groups and its correlation with the number of visits was compared using repeated measures analysis of variance. ...
Idiopathic Recurrent Catatonia Needs Maintenance Lorazepam: Case Report and Review
Australian & New Zealand Journal of Psychiatry, 2007
Objectives: Catatonia as a phenomenon has been well described with either a schizophrenic illness, severe mood disorders or periodic catatonia disorder. We aim to report a patient who had recurrent catatonia that responded to and required lorazepam for maintenance. Methods: We describe the case of a 28 year old woman who had a history of recurrent catatonia that was unresponsive to most anti-psychotics, but who responded to high doses of lorazepam and needed long-term lorazepam for maintenance. Results and Conclusion: Our patient met the criteria for a diagnosis of idiopathic catatonic disorder. Response to lorazepam suggests that a certain group of patients may require long-term treatment with lorazepam, especially those who may have down-regulation of GABA-A receptors.
Synergism of lorazepam and electroconvulsive therapy in the treatment of catatonia
Biological Psychiatry, 1997
Electroconvulsive therapy (ECT) and lorazepam are effective treatments ,for catatonia. ECT combined with benzodiazepines has been associated with reduced efficacy and efficiency and therefore is not recommended in the routine practice of ECT. We report 5 prospectively identified cases of catatonia treated either sequentially or concurrently with lorazepam and ECT. In each case, the combination of lorazepam with ECT was superior to monotherapy. This apparent synergism, its possible mechanisms, and its implications for treating catatonia are discussed.

Benzodiazepine withdrawal symptoms vary from mild anxiety to life-threatening delirium or seizures. In susceptible individuals, such as those with mood disorders, benzodiazepine withdrawal may also precipitate catatonia. A 26-year-old man with schizoaffective disorder (depressed type with catatonia) ran out of lorazepam and presented with catatonia, delirium, and seizures. He was taking olanzapine, venlafaxine, and trazodone for schizoaffective disorder. Lorazepam 2 mg twice daily kept him free of catatonia for 6 months. Besides catatonia and delirium, lorazepam withdrawal also triggered convulsive seizures and nonconvulsive status epilepticus. He was admitted to the intensive care unit where he underwent continuous video-EEG monitoring. Catatonia resolved with lorazepam on day 2. Seizures stopped with levetiracetam, lacosamide, and propofol on day 4. His mental status was normal when he was discharged on day 6. If not immediately recognized and treated, catatonia and delirium can l...
Catatonia: Clinical Overview of the Diagnosis, Treatment, and Clinical Challenges
Neurology International, 2021
Catatonia is a syndrome that has been associated with several mental illness disorders but that has also presented as a result of other medical conditions. Schizophrenia and other psychiatric disorders such as mania and depression are known to be associated with catatonia; however, several case reports have been published of certain medical conditions inducing catatonia, including hyponatremia, cerebral venous sinus thrombosis, and liver transplantation. Neuroleptic Malignant Syndrome and anti-NMDA receptor encephalitis are also prominent causes of catatonia. Patients taking benzodiazepines or clozapine are also at risk of developing catatonia following the withdrawal of these medications—it is speculated that the prolonged use of these medications increases gamma-aminobutyric acid (GABA) activity and that discontinuation may increase excitatory neurotransmission, leading to catatonia. The treatment of catatonia often involves the use of benzodiazepines, such as lorazepam, that can ...
Systematic review of catatonia treatment
Neuropsychiatric Disease and Treatment, 2018
Objective: To investigate the evidence-based treatment of catatonia in adults. The secondary aim is to develop a treatment protocol. Materials and methods: A systematic review of published treatment articles (case series, cohort or randomized controlled studies) which examined the effects of particular interventions for catatonia and/or catatonic symptoms in adult populations and used valid outcome measures was performed. The articles for this review were selected by searching the electronic databases of the Cochrane Library, MEDLINE, EMBASE and PSYCHINFO. Results: Thirty-one articles met the inclusion criteria. Lorazepam and electroconvulsive therapy (ECT) proved to be the most investigated treatment interventions. The response percentages in Western studies varied between 66% and 100% for studies with lorazepam, while in Asian and Indian studies, they were 0% and 100%. For ECT, the response percentages are 59%-100%. There does not seem to be evidence for the use of antipsychotics in catatonic patients without any underlying psychotic disorder. Conclusion: Lorazepam and ECT are effective treatments for which clinical evidence is found in the literature. It is not possible to develop a treatment protocol because the evidence for catatonia management on the basis of the articles reviewed is limited. Stringent treatment studies on catatonia are warranted.

Sleep variables and psychiatric symptoms during benzodiazepine (BZD) hypnotic therapy and during zopiclone (ZPC) treatment were investigated in 6 male chronic schizophrenics. The amount of stage 1 was smaller and that of stage 2 was larger during treatment with ZPC than BZDs. However, no significant difference was shown in the amount of slow-wave sleep (SWS) between the treatments. Both the total and negativesymptom scores in the Brief Psychiatric Rating Scale (BPRS) were lower, and the soundness of sleep in the subjective sleep assessments was better evaluated during treatment with ZPC than BZDs. These results suggest that ZPC may be more beneficial in treating schizophrenic insomnia than BZDs. creased total sleep time and sleep efficiency, fragmentation of sleep, reduced slow-wave sleep (SWS), decreased or increased amounts of REM sleep, prolonged sleep latency, and shortened REM latency.

Malignant catatonia responsive to low doses of lorazepam: case report
Sao Paulo Medical Journal, 2015
CONTEXT: Catatonia can be divided into non-malignant or malignant. The latter is characterized by autonomic instability, exhibiting high fever, tachycardia and hypertension, and is regarded as a fulminant and rapidly progressive subtype. CASE REPORT: This article reports a case of malignant catatonia in a 43-year-old patient who had been presenting psychiatric disorders for the last three years. The patient was stable, maintaining mutism, immobility and autonomic abnormalities. Oral lorazepam (1 mg every eight hours) was introduced and, in a few hours, the patient became afebrile. Two days later, the patient was already responding to verbal commands. CONCLUSIONS: Early intervention with lorazepam reduced the evolution of this patient to a fatal complication. Therefore, this case report sought to show that early diagnosis and intervention reduced the occurrence of serious and irreversible clinical outcomes.
