A case of schizophrenia with relapsed catatonia successfully treated with blonanserin transdermal patch.

BACKGROUND: Catatonia is a syndrome that may present with stupor, immobility, and postural retention, and appears in various primary disorders including schizophrenia, depressive disorders, and neurodevelopmental disorders. CASE PRESENTATION: In this report, we describe a 34-year-old female patient with schizophrenia, who had previously been treated with antipsychotic agents to improve psychotic symptoms with delusional symptoms and catatonia. However, she relapsed with catatonic symptoms around 1 year after she voluntarily discontinued the prescribed antipsychotic medications by herself. Her catatonia was successfully improved using the transdermal blonanserin patch, a drug formulation globally first approved in Japan in 2019. DISCUSSION: Although benzodiazepines or electroconvulsive therapy have been recommended as the first-line treatment of catatonic manifestation observed in psychiatric patients, this patient responded well to antipsychotic blonanserin. From the differential drug responses, catatonia may be the complex of heterogeneous conditions with different pathophysiologies.

Co-Occurring Catatonia and COVID-19 Diagnoses Among Hospitalized Individuals in 2020: A National Inpatient Sample Analysis.

BACKGROUND: COVID-19 is associated with a range of neuropsychiatric manifestations. While case reports and case series have reported catatonia in the setting of COVID-19 infection, its rate has been poorly characterized. OBJECTIVE: This study reports the co-occurrence of catatonia and COVID-19 diagnoses among acute care hospital discharges in the United States in 2020. METHODS: The National Inpatient Sample, an all-payors database of acute care hospital discharges, was queried for patients of any age discharged with a diagnosis of catatonia and COVID-19 in 2020. RESULTS: Among 32,355,827 hospitalizations in the 2020 National Inpatient Sample, an estimated 15,965 (95% confidence interval: 14,992-16,938) involved a diagnosis of catatonia without COVID-19 infection, 1,678,385 (95% confidence interval: 1,644,738-1,712,022) involved a diagnosis of COVID-19 without a co-occurring catatonia diagnosis, and 610 (95% confidence interval: 578-642) involved both catatonia and COVID-19 infection. In an adjusted model, a diagnosis of COVID-19, but not a diagnosis of catatonia or the combination of catatonia and COVID-19, was associated with increased mortality. Patients with catatonia and COVID-19 were frequently diagnosed with encephalopathy and delirium codes. CONCLUSIONS: Catatonia and COVID-19 were rarely co-diagnosed in 2020, and catatonia diagnosis was not associated with increased mortality in patients with COVID-19. Further research is needed to better characterize the phenomenology of catatonia in the setting of COVID-19 infection and its optimal treatment.

Covid-19 Induced Catatonia: A Review Of This Rare Phenomenon.

BACKGROUND: Catatonia is a psychomotor syndrome characterized by numerous clinical features, a few being stupors which is the most common sign, posturing, forced grasping, echopraxia, etc. There have been cases documented in the literature of Catatonia occurring with COVID-19. This article will focus on the complete and brief overview of catatonia observed in patients with COVID-19 infection. METHODS: We outline the evidence of the pathophysiology of COVID-19 in the CNS system, the effect of the virus in inducing catatonia, and its outcome. The literature used in the article is mostly case reports from different parts of the world thus; we have generalized our review taking into consideration multiple factors. RESULTS: In patients with COVID-19, neuropsychiatric manifestations are very commonly appreciated. Catatonia has been documented in many patients along with respiratory symptoms such as fever, shortness of breath, and cough. There are multiple etiologies associated with this presentation which have been discussed in detail in this article. In many patients, there was no history of any psychiatric illness. The timing of presenting with catatonic features was also different for different individuals. CONCLUSIONS: COVID-19 has been believed to contribute to the presentation of catatonia. There is no specific timeline between the onset of symptoms and the presence of COVID-19 infection. However, coronavirus can be responsible in a few ways for inducing catatonia in patients with or without any previous psychiatric illness. Therefore, COVID-19 should be considered as one of the major factors in this complex psychiatric disease, catatonia.

Concurrent catatonia and COVID-19 infection - An experiential account of challenges and management of cases from a tertiary care psychiatric hospital in India.

Catatonia has been reported as one among many neuropsychiatric manifestations associated with COVID-19 infection. Catatonia and COVID-19 co-occurrence remain clinical concerns, often posing challenges pertaining to diagnosis, and especially management. Limited information is available regarding the appropriate approaches to the management of catatonia in COVID-19 infection, particularly with reference to the safety and efficacy of benzodiazepines and Electro-convulsive therapy (ECT). We present our experience of five patients with catatonia consequent to heterogeneous underlying causes and concurrent COVID-19 infection, who received care at the psychiatric COVID unit of our tertiary care psychiatric hospital. An interesting observation included varying underlying causes for catatonia and the potential role that COVID-19 infection may have played in the manifestation of catatonia. In our experience, new-onset catatonia with or without pre-existing psychiatric illness and concurrent COVID-19 can be safely and effectively managed with lorazepam and/or ECTs. However, critical to the same is the need to implement modified protocols that integrate pre-emptive evaluation for COVID-19 disease and proactive monitoring of its relevant clinical parameters, thereby permitting judicious and timely implementation of catatonia-specific treatment options.

Catatonic syndrome as the presentation of encephalitis in association with COVID-19.

COVID-19 has shown different neurological manifestations even sometimes there are the initial or the main presentation.The following case report is about a middle-aged woman who, over 3 days, developed fever, clinical neurological alterations (stupor, muteness, fixed gaze and catatonia), cerebrospinal fluid (16 lymphocytes) and an electroencephalogram (EEG) (4-6 Hz generalised activity) with characteristics of encephalitis. A serum IgG, IgM, nasopharyngeal swab PCR for SARS-CoV-2. The patient responded positively to support measures, symptomatic and corticosteroid treatment. At discharge, the patient was independent and improved considerably.We report the presence of catatonia as a possible and atypical manifestation of encephalitis in association with COVID-19.
