Catatonia: diagnosis, classification, and treatment

Evaluating catatonia care in the psychiatric emergency room: A retrospective study

BACKGROUND

Catatonia, characterized by motor, affective, and speech disturbances, is a prevalent yet frequently misdiagnosed syndrome in the psychiatric domain, with reported prevalence ranging from 5% to 18%. This study aimed to ascertain the incidence of catatonia diagnoses and the quality of care provided within the psychiatric emergency room (ER), while also evaluating psychiatrists' general awareness of the syndrome through a survey.

METHODS

A retrospective analysis of psychiatric ER records spanning June 18th to August 20th, 2022, was conducted to assess catatonia diagnosis frequency and treatment approaches. A Google Survey was distributed to full-time psychiatrists in the ER, querying their knowledge about catatonia prevalence, diagnostic modalities, and treatment strategies.

RESULTS

Analysis of 1118 patient records revealed a catatonia diagnosis rate of 0.36% (four cases) in the psychiatric ER. Remarkably, 75% of diagnosed patients were assessed by a single psychiatrist among nine available. Survey responses from all nine ER psychiatrists highlighted that 44% considered encountering catatonia as infrequent, while 33% regarded it as generally rare. Furthermore, 33% expressed willingness to employ potent antipsychotic interventions.

CONCLUSION

The study revealed a markedly low catatonia detection rate in the psychiatric ER, coupled with inconsistent treatment approaches. Survey findings reflected a considerable proportion of psychiatrists holding outdated perceptions of catatonia.

Phenomenology and psychiatric correlates of pseudocataplexy

STUDY OBJECTIVES

Pseudocataplexy is a rare functional neurological disorder that mimics cataplexy, pathognomonic for narcolepsy type 1 (NT1). We describe the psychiatric comorbidity and personality traits of patients with pseudocataplexy versus NT1 cases.

METHODS

The case-control observational study enrolled consecutive patients with pseudocataplexy and a control group of age-matched consecutive NT1 patients. The diagnostic work-up included a structured interview, 48-hour polysomnography, multiple sleep latency test, cataplexy provoking test, and hypocretin-1 measurement in cerebrospinal fluid. All participants were administered Beck Depression Inventory, State-Trait Anxiety Inventory, Patient Health Questionnaire-15 (PHQ-15), Personality Inventory for DSM-5 brief form, and quality-of-life (QoL) measurement by 36-item Short Form health survey (SF-36).

RESULTS

Fifteen patients with pseudocataplexy and 30 with NT1 were included. Despite the suspicion of possible cataplexy, none of the pseudocataplexy participants fulfilled international diagnostic criteria for NT1. Pseudocataplexy patients presented higher rates of moderate state anxiety (40% vs. 10%, p = 0.018), medium level of somatic symptoms, defined by PHQ-15 score > 10 (66.7% vs. 16.7%, p = 0.003), and a trend towards moderate-to-severe depressive symptoms (33.3% vs. 10%, p = 0.054) compared to NT1. No significant differences in personality traits emerged. Pseudocataplexy patients had worse QoL profiles in almost all SF-36 domains including physical (mean ± SD: 37.7 ± 9.88 vs. 51.13 ± 7.81, p < 0.001) and mental (mean ± SD: 33.36 ± 12.69 vs.42.76 ± 11.34, p = 0.02) summary scores.

CONCLUSIONS

Patients with pseudocataplexy present more severe psychiatric symptoms and a lower QoL profile in comparison with patients with NT1. The severe somatoform and affection impairment in pseudocataplexy may explain the poorer QoL and should require a tailored therapeutic approach.

Catatonia in autism spectrum disorders: Prevalence, functional impact, and diagnostic insights

The current study aimed to evaluate subtle catatonia behaviors and functionality in adolescents with autism spectrum disorders (ASD). The sample consisted of 48 patients (11 female, 37 male) aged 12-18 (13.77 ± 2.01). DSM-5 catatonia criteria and Bush-Francis Catatonia Rating Scale (BCRS) was utilized to assess catatonia, while the impairment in functionality was appraised using the Global Assessment Scale. Parents fulfilled the Revised Child Anxiety and Depression Scale-Parent version (RCADS-PV) and Repetitive Behavior Scale-Revised (RBS-R). The presence of catatonia was detected in 18 out of 48 (37.5 %) participants according to BCRS, and in 16 cases (35.4 %) according to DSM-5 criteria. A significant association between two diagnostic tools was observed (p < 0.001). In the group with mild impairment in functionality, 2 cases had catatonia (12.5 %), while in the group with more impaired functionality, 16 cases (50 %) had catatonia (p = 0.011) according to BCRS. Major depressive disorder subscale scores of RCADS-PV and stereotypic movements (RBS-R) were correlated with the presence of catatonia (p < 0.05). The findings suggest a higher prevalence of catatonia in ASD, and a potential correlation between the presence of catatonia and functionality. More research is warranted to highlight the presence and course of catatonia beginning from the early years of ASD.

Frontal Glioblastoma Presenting With Catatonia: A Case Report

This case highlights the need for thorough medical and neurological screening before making any psychiatric diagnosis, even if the patient has a classical syndromic presentation. Presented here is a case of a female in her late 40s coming to our psychiatric outpatient with symptoms suggestive of catatonia. She was treated at a private clinic for depression. As her symptoms deteriorated, she was brought to our hospital for further management. She was diagnosed with catatonia during admission assessment. A detailed neurological assessment later revealed slight weakness in the right upper and lower limb. Following this, a CT scan was done and was reported to have a hypodense area involving the bilateral frontal and basifrontal region, more pronounced on the left side (likely to be acute/subacute). MRI was subsequently done and was found to be suggestive of glioblastoma NOS (not otherwise specified) involving the bilateral cerebral hemisphere which was later confirmed by the histopathology report.

Drug-related catatonia in youths: real-world insights from the WHO Safety Database

Catatonia is characterized by psychomotor alterations and reduced contact with the environment. Initially linked to schizophrenia, it also occurs in mood disorders or organic conditions. In children, catatonia remains poorly delineated, despite dramatically increasing the risk of premature death. As data on pediatric drug-induced catatonia bears many uncertainties, we aimed to characterize its age-dependent patterns, using real-world data from the WHO safety database (VigiBase®).VigiBase® was queried for all reports of catatonia registered up to December 8th 2022. Reports involving patients <18 years were classified into 3 groups: ≤23 months, 2-11 years, and 12-17 years. Disproportionality analyses relied on the Reporting Odds Ratio (ROR), and the positivity of the lower end of the 95% confidence interval of the Information Component (IC) was required to suspect a signal. Catatonia was evoked in 421 pediatric reports. In infants, vaccines were leading. In children, the main signals involved haloperidol (ROR 104.3; 95% CI 45.6-238.5), ondansetron (ROR 40.5; 95% CI 16.5-99.5), and ciclosporin (ROR 27.4; 95% CI 13.8-54.1). In adolescents, chlorpromazine (ROR 199.1; 95% CI 134.8-294.1), benzatropine (ROR 193; 95% CI 104.1-361.6), and olanzapine (ROR 135.7; 95% CI 104.6-175.9) reached the highest RORs. In infants, catatonia was related to vaccines, it was ascribed to multiple drugs in children, and mainly to psychotropic drugs in adolescents. Less suspected drugs, such as ondansetron, were highlighted. Despite limitations inherent in spontaneous reporting systems, this study supports that a careful anamnesis is warranted to separate catatonia associated with medical conditions from drug-induced catatonia in pediatric patients.

The Role of Electroconvulsive Therapy in the Treatment of Catatonia Associated With Lewy Body Dementia: A Case Report

Catatonia is a complex amalgamation of neuropsychiatric symptoms that can manifest in both psychiatric and neurological conditions. The treatment of catatonia related to psychiatric illnesses is well documented as it typically responds to benzodiazepines and electroconvulsive therapy (ECT). However, the treatment of catatonia related to neurological disorders has shown to be more difficult, particularly when associated with Lewy Body Dementia (LBD). Here, we present the case of a 78-year-old woman with LBD, Bipolar I, depressive type, who successfully underwent twelve ECT sessions to treat catatonia refractory to benzodiazepine therapy. The effectiveness of the treatment was measured using the Bush-Françis Catatonia Scale (BFCS) to measure her catatonic symptoms as she progressed through the therapy. This report highlights the importance of considering ECT as a leading therapeutic approach in this particular subset of patients who do not respond adequately to pharmaceutical therapy and medical titrations.

Catatonia: A Narrative Review for Hospitalists

Background

Catatonia is a complex psychomotor syndrome commonly associated with psychiatric disorders. However, hospitalists encounter this condition on medical floors, where it is typically due to an underlying medical, especially neurological, etiology. Delays in the diagnosis of catatonia are common and lead to worsened outcomes for patients, including a multitude of medical complications, such as venous thromboembolism and stasis ulcers. Catatonia due to a medical condition is less likely to respond to benzodiazepine therapy; identification and treatment of the underlying cause is crucial.

Methods

This article provides a practical review of the catatonia literature, with a focus on diagnosis, workup, and management of catatonia for patients admitted to medical hospitals.

Conclusions

With greater knowledge about catatonia, internists are uniquely positioned to recognize and initiate treatment.

Catatonia in a Patient With Bipolar Affective Disorder and Hypothyroidism: A Diagnostic and Therapeutic Challenge

This case report presents the clinical course of a 33-year-old female with a history of bipolar affective disorder (BAD) who presented to the psychiatric emergency department with sudden-onset altered behavior, along with features indicative of catatonia. Before hospitalization, the patient had not been adherent to psychiatric medications for BAD for a period of several months, likely a contributing factor to the patient's presenting symptoms. Over a two-week period before hospitalization, the patient exhibited progressive withdrawal, psychomotor retardation, disorganized behavior, and a lack of response to external stimuli. Initial labs upon admission had findings consistent with a diagnosis of hypothyroidism. The patient had no prior history of thyroid disease and further endocrinology workup was deferred by the hospitalist to outpatient care upon discharge. While initially in the emergency department, the patient received intramuscular lorazepam for immediate symptom relief, the initial response to the Ativan challenge was not fully documented. Upon evaluation by the inpatient team the next morning, a Bush-Francis Catatonia Rating Scale score of 22 highlighted the severity of catatonia, which may have been further exacerbated by concurrent hypothyroidism. As such, thyroid hormone replacement therapy (levothyroxine) was indicated to normalize thyroid function. Combination treatment initially with lorazepam and levothyroxine was administered for the patient's catatonia and olanzapine was chosen as the anti-psychotic. Over the subsequent days, the patient's catatonic symptoms demonstrated positive responses to treatment, prompting adjustments in pharmacotherapy. The patient eventually returned to baseline functioning, with substantial improvements in catatonia as well as mood symptoms. This case underscores the complex interplay between catatonia, bipolar affective disorder, and thyroid dysfunction. The timely identification and management of hypothyroidism in the context of catatonia showcase the potential for favorable outcomes with targeted interventions.

Catatonia, Pregnancy, and Electroconvulsive Therapy (ECT)

Background

Catatonia is a neuropsychiatric syndrome, which typically occurs in the context of another psychiatric or medical condition, with a significant morbidity and mortality risk. Significant medical conditions resulting from catatonia include nutritional deficiencies, skin ulcerations, electrolyte disturbances, aspiration pneumonia, and venous thromboembolism. As a result, prompt treatment is required. Gold standard treatment consists of benzodiazepines, followed by electroconvulsive therapy (ECT) if pharmacotherapy alone is ineffective. With pregnancy and catatonia, there is a high risk of adverse maternal/fetal outcomes, and the risks/benefits of treatment must be carefully considered.

Case

Here, we present a case of a young pregnant woman with schizoaffective disorder whose catatonic state was not successfully resolved with lorazepam, therefore requiring ECT. Patient presented to the emergency department at 20 weeks of pregnancy, displaying symptoms of catatonia and psychosis. She was admitted to the inpatient behavioral health unit, where she was treated with lorazepam for catatonia. Treatment occurred in close collaboration with the obstetrics team. While initially, the patient appeared to have a positive response to lorazepam, she became increasingly catatonic with minimal oral intake, mutism, and urinary retention. As a result, she was transferred to the medical floor, where ECT was initiated due to the ineffectiveness of lorazepam. Her catatonia was successfully resolved with 12 total treatments of ECT; there were no adverse effects to the fetus. Patient delivered her baby at 39 weeks with no complications. She continued to receive inpatient psychiatric care until she was stable for discharge to an extended acute care unit.

Objectives

In this report, we will review relevant literature on catatonia in pregnancy, with focus on treatment with ECT.

Conclusions

Though the literature on these topics is limited and typically presented in case reports format, there appears to be a favorable view toward the use of ECT for pregnant catatonic patients. This case could be considered a vital contribution to the literature, as it provides a successful example of treating catatonia in pregnancy with no known adverse effects to the mother or child.

Malignant Catatonia: A Review for the Intensivist

Catatonia is a clinical syndrome characterized by psychomotor, neurological and behavioral changes. The clinical picture of catatonia ranges from akinetic stupor to severe motoric excitement. Catatonia can occur in the setting of a primary psychiatric condition such as bipolar disorder or secondary to a general medical illness like autoimmune encephalitis. Importantly, it can co-occur with delirium or coma. Malignant catatonia describes catatonia that presents with clinically significant autonomic abnormalities including change in temperature, blood pressure, heart rate, and respiratory rate. It is a life-threatening form of acute brain dysfunction that has several motoric manifestations and occurs secondary to a primary psychiatric condition or a medical cause. Many of the established predisposing and precipitating factors for catatonia such as exposure to neuroleptic medications or withdrawal states are common in the setting of critical illness. Catatonia typically improves with benzodiazepines and treatment of its underlying psychiatric or medical conditions, with electroconvulsive therapy reserved for catatonia refractory to benzodiazepines or for malignant catatonia. However, some forms of catatonia, such as catatonia secondary to a general medical condition or catatonia comorbid with delirium, may be less responsive to traditional treatments. Prompt recognition and treatment of catatonia are crucial because malignant catatonia may be fatal without treatment. Given the high morbidity and mortality associated with malignant catatonia, intensivists should familiarize themselves with this important and under-recognized condition.

The role of the electroencephalogram (EEG) in determining the aetiology of catatonia: a systematic review and meta-analysis of diagnostic test accuracy

Background

Catatonia is a psychomotor syndrome that has a wide range of aetiologies. Determining whether catatonia is due to a medical or psychiatric cause is important for directing treatment but is clinically challenging. We aimed to ascertain the performance of the electroencephalogram (EEG) in determining whether catatonia has a medical or psychiatric cause, conventionally defined.

Methods

In this systematic review and meta-analysis of diagnostic test accuracy (PROSPERO CRD42021239027), Medline, EMBASE, PsycInfo, and AMED were searched from inception to May 11, 2022 for articles published in peer-reviewed journals that reported EEG findings in catatonia of a medical or psychiatric origin and were reported in English, French, or Italian. Eligible study types were clinical trials, cohort studies, case-control studies, cross-sectional studies, case series, and case reports. The reference standard was the final clinical diagnosis. Data extraction was conducted using individual patient-level data, where available, by two authors. We prespecified two types of studies to overcome the limitations anticipated in the data: larger studies (n ≥ 5), which were suitable for formal meta-analytic methods but generally lacked detailed information about participants, and smaller studies (n < 5), which were unsuitable for formal meta-analytic methods but had detailed individual patient level data, enabling additional sensitivity analyses. Risk of bias and applicability were assessed with the QUADAS-2 tool for larger studies, and with a published tool designed for case reports and series for smaller studies. The primary outcomes were sensitivity and specificity, which were derived using a bivariate mixed-effects regression model.

Findings

355 studies were included, spanning 707 patients. Of the 12 larger studies (5 cohort studies and 7 case series), 308 patients were included with a mean age of 48.2 (SD = 8.9) years. 85 (52.8%) were reported as male and 99 had catatonia due to a general medical condition. In the larger studies, we found that an abnormal EEG predicted a medical cause of catatonia with a sensitivity of 0.82 (95% CI 0.67-0.91) and a specificity of 0.66 (95% CI 0.45-0.82) with an I 2 of 74% (95% CI 42-100%). The area under the summary ROC curve offered excellent discrimination (AUC = 0.83). The positive likelihood ratio was 2.4 (95% CI 1.4-4.1) and the negative likelihood ratio was 0.28 (95% CI 0.15-0.51). Only 5 studies had low concerns in terms of risk of bias and applicability, but a sensitivity analysis limited to these studies was similar to the main analysis. Among the 343 smaller studies, 399 patients were included, resulting in a sensitivity of 0.76 (95% CI 0.71-0.81), specificity of 0.67 (0.57-0.76) and AUC = 0.71 (95% CI 0.67-0.76). In multiple sensitivity analyses, the results were robust to the exclusion of reports of studies and individuals considered at high risk of bias. Features of limbic encephalitis, epileptiform discharges, focal abnormality, or status epilepticus were highly specific to medical catatonia, but features of encephalopathy had only moderate specificity and occurred in 23% of the cases of psychiatric catatonia in smaller studies.

Interpretation

In cases of diagnostic uncertainty, the EEG should be used alongside other investigations to ascertain whether the underlying cause of catatonia is medical. The main limitation of this review is the differing thresholds for considering an EEG abnormal between studies.

Challenges of treating catatonia in the community setting without access to electroconvulsive therapy

Catatonia is a psychomotor syndrome resulting from an underlying psychiatric or medical disorder commonly observed in inpatient psychiatric units. While benzodiazepines and electroconvulsive therapy (ECT) are effective treatment options, the unavailability of ECT in many community psychiatric hospitals in the United States negatively affects patient outcomes. We present a 25-year-old African American male with a psychiatric diagnosis of schizophrenia complicated by malignant catatonia who was admitted to a community psychiatric hospital. He required intensive medical stabilization with supportive management, and transfer requests to ECT-equipped hospitals were initiated. While awaiting transfer for 148 days, the patient's symptoms did not fully remit with lorazepam (even with 36 mg daily in divided doses) and other psychotropic medication trials, including antipsychotics and mood stabilizers. After nearly 5 months of inpatient stay, he was successfully transferred, received ECT treatment, and experienced rapid resolution of catatonia. After discharge, to obtain three monthly sessions of maintenance ECT, he had 5-h one-way ground transportation arranged to an out-of-county ECT-equipped facility. There was no relapse in catatonia by the 2-year follow-up. This report highlights a significant healthcare disparity when attempting to manage severe catatonia within community hospital settings without access to ECT in the United States. Alternative treatments, including antipsychotics, had minimal impact on symptoms and possibly increased morbidity in this case while awaiting ECT. Treatment at our designated safety net hospital still required referral to 14 ECT-equipped hospitals before successful transfer. This case highlights the urgent need for ECT availability in more community hospitals to treat patients with refractory psychiatric conditions, including catatonia. ECT is an essential psychiatric treatment that, for certain conditions, has no appropriate alternatives. We propose that access to ECT be considered in the determination of safety net hospital systems, with improved ability to transfer patients who are suffering from treatable life-threatening mental health conditions.

Electroconvulsive Treatment Utilization for Inpatient Management of Catatonia in Adolescents With Schizophrenia Spectrum Disorders

OBJECTIVE

The aim of this study was to determine rates of electroconvulsive therapy (ECT) use for catatonia in schizophrenia spectrum disorders, stratified by patient demographics and hospital characteristics, and its impact on inpatient length of stay and cost.

METHODS

We found 155 adolescents (aged 12-18 years) with principal discharge diagnosis of schizophrenia spectrum disorders with catatonia from the National Inpatient Sample. They were subgrouped into ECT (n = 20) and non-ECT (n = 135) groups. We used descriptive statistics to evaluate the utilization of ECT for catatonia and independent-sample t test for continuous variables with statistical significance at P ≤ 0.05.

RESULTS

The overall utilization rate of ECT in adolescents for catatonia was 12.9%. A high rate of ECT use was evident for Whites (30.8%) compared with the other race/ethnicities and also was seen in private health insurance beneficiaries (20%). The rate of ECT use varied by the region, with highest for the Northeast (20%), followed by the South (18.2%), and the West (14.3%). Adolescent inpatients with catatonia in public and teaching type, and large bed-size hospitals were more likely to receive ECT than their counterparts. The mean number of ECT sessions required during the inpatient stay was 5.2 (range, 1-15), and the mean number of days from admission to initial ECT was 2.5 (range, 0-6).

CONCLUSIONS

Electroconvulsive therapy is used for approximately only 13% of adolescents with catatonia when comorbid schizophrenia spectrum disorders are present, suggesting that many patients may not get evidence-based treatment. Future studies in this area are needed.

An Overlapping Presentation of Hypoglycemia and Catatonia—A Case Report and Literature Review

Catatonia is a clinical syndrome characterized by a distinct constellation of psychomotor disturbances. It is known as a clinical manifestation of many medical and psychiatric conditions. Neuroglycopenia is a term that refers to a shortage of glucose in the brain resulting in the alteration of neuronal function. Catatonia has been observed in hypoglycemic states. We present a single case report of a 36-year-old male, with no known medical or psychiatric history, presenting with catatonia and hypoglycemia due to malnutrition. Catatonia and hypoglycemia may present similarly, and can present a challenge in differentiating the underlying etiology. It is unclear whether the hypoglycemia-catatonia overlap phenomenon is rare or rather underdiagnosed.

Therapy of Catatonia in Schizophrenia and Schizophrenia Spectrum Disorders

Background: the study of catatonia’s treatment methods is one of the most important researchers’ tasks, nevertheless the common therapeutic strategies of cupping the catatonic phenomena haven’t been created yet. The aim: review to therapeutic interventions for catatonic disorders in schizophrenia.Materials and methods: according to the keywords “catatonia treatment”, “catatonia therapy”, publications found in the Scopus, PubMed, Cochrane Library, eLibrary databases were selected and analyzed.Results: historical background, illustrating the development of catatonia treatment methods, is given; the results of the last decades scientific studies of catatonia’s treatment and preliminary results of own study, devoted to the effectiveness of diazepam and cariprazine in relieving catatonia manifestations are presented. Based on the studies’ results, presented in the review, it can be concluded that the most common modern method of treating catatonic disorders is the use of benzodiazepines, however, in some cases, the use of antipsychotics is also advisable. Electroconvulsive therapy (ECT) remains an important treatment for catatonic phenomena. There are also isolated clinical cases of successful testing of both: other pharmacological groups (antidepressants, dopaminergic and anticholinergic drugs, normothymic drugs, etc.) and non-drug interventions (transcranial magnetic stimulation — TMS) presented in modern research data.Conclusion: the effectiveness of benzodiazepines in catatonia, associated with schizophrenia and schizophrenia spectrum disorders (SSD), remains controversial according to modern authors’ opinion. In turn, among antipsychotics, antipsychotics of the second and third generation seem to be safe for the treatment of psychomotor symptoms. In accordance with the results of our own study, catatonia in the structure of schizophrenia and SSD is heterogeneous and, depending on the psychopathological structure of catatonic disorders, a different reaction of psychomotor symptoms to therapeutic intervention was observed.

Management and outcomes of catatonia: A prospective study in urban South Africa

Objectives

Rapid intervention for catatonia with benzodiazepines and electroconvulsive therapy can prevent fatal complications. We describe the management and treatment response of 44 patients with catatonia in a psychiatric unit in urban South Africa. The objective was to screen admissions for catatonia and investigate management, treatment response, and treatment outcomes.

Method

We used a prospective, descriptive, observational study design and collected data using a data collection sheet, the Bush Francis Catatonia Screening Instrument, the Bush Francis Catatonia Rating Scale, and the Diagnostic Statistical Manual-5 to assess catatonia in new admissions from September 2020 to August 2021.

Results

Of the 241 participants screened on admission, 44 (18.3% of 241) screened positive for catatonia on the Bush Francis Catatonia Screening Instrument, while 197 (81.7% of 241) did not. Thirty-eight (86.4% of 44) received lorazepam, seven (15.9%) received clonazepam, and two (4.6%) received diazepam, implying that three (6.8%) of the 44 participants with catatonia received more than one benzodiazepine sequentially. Ten (22.7% of 44) patients received electroconvulsive therapy. Seven of those treated with electroconvulsive therapy (15.9% of 44 and 70% of 10) responded well and were discharged, whereas 22 (50% of 44 and 64.7% of 34) of those given lorazepam were discharged. Patients treated with electroconvulsive therapy had a higher initial Bush Francis Catatonia Rating Scale score. One patient (2.3%) relapsed within 4 weeks of discharge. Twenty (45.5%) of the 44 patients with catatonia had low average iron levels, 14 (31.8%) had low vitamin B12, and 24 (54.6%) had high creatinine kinase.

Conclusion

Both lorazepam and electroconvulsive therapy were found to be effective treatments for catatonia with good response and outcomes. The length of hospital stay of patients with catatonia was similar to that of patients without catatonia. Treatment guidelines for catatonia need to include the role and timing of electroconvulsive therapy to augment current treatment protocols for the use of lorazepam.

Catatonia in older adults: A systematic review

BACKGROUND

Catatonia is a complex psychomotor syndrome that often goes unrecognized and untreated, even though its classification has evolved in recent years. Prompt and correct identification of catatonia allows for highly effective treatment and prevention of possible complications. The underrecognition of catatonia in older patients is also frequent, and research in this population is scarce.

AIM

To conduct a systematic review of the literature on catatonia in older people to ascertain its clinical characteristics across settings.

METHODS

Following the PRISMA guidelines, MEDLINE, EMBASE, and PsycINFO databases were searched from inception to December 2021, with a strategy aimed at identifying all articles published on catatonia in older adults. Titles and abstracts were scanned and selected independently by two authors. Papers investigating issues related to catatonia and/or catatonic symptoms in older people, with English abstracts available, were included. References of selected articles were revised to identify other relevant studies.

RESULTS

In total, 1355 articles were retrieved. After removing duplicates, 879 remained. Of the 879 identified abstracts, 669 were excluded because they did not meet the inclusion criteria. A total of 210 articles underwent full text review, and 51 were eliminated for various reasons. Fourteen more articles were selected from the references. Overall, 173 articles were reviewed: 108 case reports, 35 case series, 11 prospective cohort studies, 6 case-control studies, 3 retrospective cohort studies and 10 reviews. We found several particular aspects of catatonia in this population. Catatonia in older patients is highly prevalent and tends to have a multifactorial etiology. Older patients, compared to younger patients, have a higher risk of developing catatonia with benzodiazepine (BZD) withdrawal, in bipolar disorder, and in the general hospital. Age, together with other risk factors, was significantly associated with the incidence of deep venous thrombosis, neuroleptic malignant syndrome poor outcome, other complications and mortality. Treatment with BZDs and electroconvulsive therapy is safe and effective. Prompt treatment of its cause is essential to ensure a good prognosis.

CONCLUSION

Catatonia in older patients is highly prevalent and tends to have a multifactorial etiology. The risk of developing catatonia in some settings and conditions, as well as of developing complications, is high in this population. Symptomatic treatment is safe and effective, and timely etiologic treatment is fundamental.

Catatonia: Clinical Overview of the Diagnosis, Treatment, and Clinical Challenges

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 be used in combination therapy with antipsychotics. Definitive treatment may be found with electroconvulsive therapy (ECT). Aberrant neuronal activity in different motor pathways, defective neurotransmitter regulation, and impaired oligodendrocyte function have all been proposed as the pathophysiology behind catatonia. There are many clinical challenges that come with catatonia and, as early treatment is associated with better outcomes, it becomes imperative to understand these challenges. The purpose of this manuscript is to provide an overview of these challenges and to look at clinical studies regarding the pathophysiology, diagnosis, and treatment of as well as the complications and risk factors associated with catatonia.

Electroconvulsive Therapy in Children and Adolescents: A Systematic Review of Current Literature and Guidelines

ABSTRACT

There is a lack of studies regarding the efficacy of electroconvulsive therapy (ECT) in children and adolescents. In this study, we aimed to assess benefits and harms of ECT in children and adolescents with major psychiatric diseases. We conducted a systematic search in PubMed, EMBASE, and PsycINFO for peer-reviewed articles written in English regarding the use of ECT as treatment for major psychiatric diseases in children and adolescents. This study consists of 192 articles, mostly case studies (n = 50), reviews and overview articles (n = 52), and retrospective studies (n = 30). We present an overview of evidence for ECT in children and adolescents with mood disorders, catatonia, schizophrenia, intellectual disability, self-injurious behavior, and other indications. This article is also a summary of international guidelines regarding the use of ECT in children and adolescents. We evaluated the overall quality of evidence by using Grading of Recommendations, Assessment, Development and Evaluations and found the overall level of evidence to be of low quality. There are no absolute contra indications for ECT in children and adolescents. Fears regarding cognitive dysfunction have not been reproduced in studies. Electroconvulsive therapy should be considered in severe, treatment-resistant mood disorders, catatonia, and schizophrenia, especially in older adolescents. High-quality studies are warranted to assess the efficacy of ECT, especially in these potentially life-threatening diseases.

Periodic Catatonia: Long-term Treatment With Lamotrigine: A Case Report

Periodic catatonia is a rare form of catatonia, characterized by episodes occurring in a cyclic pattern with clinical features of combined stupor and excitement, with intervals of remission. Although periodic catatonia is not common, it is an urgent condition, requiring hospitalization for evaluation and treatment. The management of periodic catatonia is quite challenging, mainly because of the unknown pathophysiological mechanisms involved in the onset of this clinical entity, which are less clear than in other forms of catatonia. Although positive trials of several medications in the acute phase of periodic catatonia have been published, available literature concerning the prevention of recurrent catatonic episodes is scarce. Here, we present the case of a patient with periodic catatonia in which long-term treatment with lamotrigine appears to have acted prophylactically in reducing the occurrence and severity of new catatonic episodes. A better understanding of the mechanisms involved in the pathophysiology of periodic catatonia and increasing psychiatrists' and physicians' awareness of the presentation of this clinical entity could be of benefit in shedding light on the most appropriate treatment approach. However, further clinical studies are needed before any firm recommendations can be made.

Commentary: Diagnostic and Treatment Issues in Psychosis

The 3 cases presented in this issue highlight challenges in evaluating and treating patients with psychotic symptoms. The first case involved the rare but debilitating condition of periodic catatonia, the second case involved the use of intranasal oxytocin to augment an antipsychotic for a patient with worsening psychotic symptoms (and a prior diagnosis of schizophrenia) in the postpartum period, and the third case involved auto-enucleation (often referred to as "Oedipism"), a violent form of self-mutilation, in a patient presenting with first-episode schizophrenia. These case reports reinforce the need to consider a wide differential diagnosis before initiating treatment. Understanding the broad spectrum with which psychotic symptoms can present, or rare presentations of more common conditions, can help clarify the diagnosis and guide treatment, and hopefully help prevent or reduce future self-harm or violence, psychotic episodes, and hospitalizations.

Clozapine Withdrawal-Induced Malignant Catatonia or Neuroleptic Malignant Syndrome: A Case Report and a Brief Review of the Literature

ABSTRACT

In our brief literature review, we discuss the changes in the concept of catatonia as well as its various types and symptoms. We also succinctly review the possible symptoms of clozapine withdrawal. In addition, we analyze the main features of the very few published cases of clozapine withdrawal-induced catatonia and the relationship between neuroleptic malignant syndrome and the malignant subtype of catatonia. Furthermore, we present the case of a 29-year-old male patient with schizophrenia in whom a malignant catatonic episode/neuroleptic malignant syndrome (with negativism, stupor, mutism, autonomic signs [eg, fever, hyperhidrosis], and elevated creatine kinase levels) began 5 days after the patient decided arbitrarily to cease his clozapine treatment. His catatonic symptoms quickly (ie, within a few days) resolved after the reinstitution of clozapine. Finally, we attempt to provide a theoretical explanation for the surprising finding in the literature that the withdrawal of clozapine, unlike the withdrawal of any other antipsychotics, may be associated with catatonia (frequently its malignant subtype). The take-home message of our case is that clinicians should bear in mind the risk of catatonia (especially the malignant subtype of it) after the prompt withdrawal of clozapine therapy.

Treatment of Catatonia with Asenapine in a Patient with Schizotypal Personality Disorder, Psychotic Depression and Septic Shock from SARSCoV- 2 - A Case Report

INTRODUCTION

Catatonia is a psychomotor syndrome that presents with severe symptoms which can lead to dangerous and lethal conditions if not diagnosed and treated properly. SARS-- CoV-2 is a positive-sense single-stranded RNA virus that can occur in severe cases with acute pneumonia, ARDS, sepsis and septic shock. In these cases, ICU admission is necessary.

CASE SUMMARY

A 59-year-old Caucasian man with septic shock and bilateral interstitial pneumonia from SARS-CoV-2 and schizotypal personality disorder presented with catatonic behaviour manifested by soporous state, response to intense painful stimuli with the opening of the eyes, execution of simple verbal commands, maintenance of the same position, catalepsy, immobility, rigidity and mutism. At the same time, there were symptoms of septic shock and catatonic symptoms, causing greater difficulty in the correct formulation of the diagnosis. During the course of his hospitalization, he was treated with asenapine 20 mg/day. The catatonia responded rapidly and significantly to the asenapine.

DISCUSSION

To date, the pathophysiology of catatonia is unclear, and few guidelines are available for the treatment of catatonia. In the literature, studies have reported the efficacy of benzodiazepines such as lorazepam and diazepam, GABAA agonists such as zolpidem, NMDA receptor antagonists such as memantine, antidepressant SSRIs such as fluoxetine and paroxetine, and antipsychotics such as olanzapine, clozapine and aripiprazole. We demonstrate that the antipsychotic asenapine is also effective in treating catatonic symptoms in psychiatric disorders.

CONCLUSION

Asenapine produced a rapid and significant reduction in catatonic symptoms in our patient with schizotypal personality disorder.

Maintenance Electroconvulsive Therapy Is an Essential Medical Treatment for Patients With Catatonia: A COVID-19 Related Experience

Aim: Describe naturalistic clinical course over 14 weeks in a mixed adolescent and a young-adult patient group diagnosed with developmental delays and catatonia, when the frequency of maintenance electroconvulsive therapy (M-ECT) was reduced secondary to 2020 COVID-19 pandemic restrictions. Methods: Participants were diagnosed with catatonia, and were receiving care in a specialized clinic. They (n = 9), F = 5, and M = 4, ranged in age from 16 to 21 years; ECT frequency was reduced at end of March 2020 due to institutional restrictions. Two parents/caregivers elected to discontinue ECT due to concern for COVID-19 transmission. Majority (n = 8) were developmentally delayed with some degree of intellectual disability (ID). Observable symptoms were rated on a three point scale during virtual visits. Results: All cases experienced clinically significant decline. Worsening of motor symptoms (agitation, aggression, slowness, repetitive self-injury, stereotypies, speech deficits) emerged within the first 3 weeks, persisted over the 14 week observation period and were more frequent than neurovegetative symptoms (appetite, incontinence, sleep). Four participants deteriorated requiring rehospitalization, and 2 among these 4 needed a gastrostomy feeding tube. Conclusion: Moderate and severe symptoms became apparent in all 9 cases during the observation period; medication adjustments were ineffective; resuming M-ECT at each participant's baseline schedule, usually by week 7, resulted in progressive improvement in some cases but the improvement was insufficient to prevent re-hospitalization in 4 cases. In summary, rapid deterioration was noted when M-ECT was acutely reduced in the setting of COVID-19 related restrictions.

Time and Body. 2020. [DOI: 10.1017/9781108776660]

Time and Body promotes the application of phenomenological psychopathology and embodied research to a broad spectrum of mental disorders. In a new and practical way, it integrates the latest research on the temporal and intersubjective constitution of the body, self and its mental disorders from phenomenological, embodied and interdisciplinary research perspectives. The authors investigate how temporal processes apply to the contribution of embodiment and selfhood, as well as to their destabilization, such as in eating disorders and borderline personality disorders, schizophrenia, depression, social anxiety or dementia. The chapters demonstrate the applicability of phenomenological psychopathology to a range of illnesses and its relevance to treatment and clinical practice.

Mental, behavioral and neurodevelopmental disorders in the ICD-11: an international perspective on key changes and controversies

An update of the chapter on Mental, Behavioral and Neurodevelopmental Disorders in the International Classification of Diseases and Related Health Problems (ICD) is of great interest around the world. The recent approval of the 11th Revision of the ICD (ICD-11) by the World Health Organization (WHO) raises broad questions about the status of nosology of mental disorders as a whole as well as more focused questions regarding changes to the diagnostic guidelines for specific conditions and the implications of these changes for practice and research. This Forum brings together a broad range of experts to reflect on key changes and controversies in the ICD-11 classification of mental disorders. Taken together, there is consensus that the WHO's focus on global applicability and clinical utility in developing the diagnostic guidelines for this chapter will maximize the likelihood that it will be adopted by mental health professionals and administrators. This focus is also expected to enhance the application of the guidelines in non-specialist settings and their usefulness for scaling up evidence-based interventions. The new mental disorders classification in ICD-11 and its accompanying diagnostic guidelines therefore represent an important, albeit iterative, advance for the field.

Catatonia in Down syndrome: systematic approach to diagnosis, treatment and outcome assessment based on a case series of seven patients

OBJECTIVE

The goal is to expand our knowledge of catatonia occurring in adolescents and young adults with Down syndrome (DS) by describing the first prospective, consecutive, well-characterized cohort of seven young people with DS diagnosed with catatonia and treated between 2013 and 2018, and to assess each patient's treatment responses. Longitudinal assessment of each patient's response to treatment is intended to provide clinicians and psychiatrists a firm foundation from which assess treatment efficacy.

STUDY DESIGN

Young adults with Down syndrome were consecutively enrolled in the study as they were diagnosed with catatonia. A comprehensive data set included medical, laboratory, developmental, demographic, family, social and genetic data, including query into disorders for which individuals with DS are at risk. Catatonia was diagnosed based on an unequivocal history of regression, positive Bush-Francis Catatonia Rating Scale and positive response to intravenous lorazepam. Patients' longitudinal progress was monitored using the Catatonia Impact Scale (CIS) developed for this purpose.

RESULTS

Seven consecutive DS patients, who presented with unequivocal regression were diagnosed with catatonia and treated for 2.7-6 years using standard-of-care therapies; primarily GABA agonist, lorazepam, electroconvulsive therapy (ECT) and glutamate antagonists (dextromethorphan/quinidine, memantine, minocycline). Responses to each treatment modality were assessed at clinic visits and through weekly electronic CIS reports.

CONCLUSION

Seven young adults with DS were diagnosed with catatonia; all responded to Lorazepam and/or ECT therapy with good to very good results. Though ECT most dramatically returned patients to baseline, symptoms often returned requiring additional ECT. Dextromethorphan/quinidine, not used until mid-2017, appeared to reduce the reoccurrence of symptoms following ECT. Though all seven patients improved significantly, each continues to require some form of treatment to maintain a good level of functioning. Findings of a significant number of autoimmune disorders and laboratory markers of immune activation in this population may guide new diagnostic and treatment opportunities.

Enhanced Automatic Action Imitation and Intact Imitation-Inhibition in Schizophrenia

Imitation plays a key role in social learning and in facilitating social interactions and likely constitutes a basic building block of social cognition that supports higher-level social abilities. Recent findings suggest that patients with schizophrenia have imitation impairments that could contribute to the social impairments associated with the disorder. However, extant studies have specifically assessed voluntary imitation or automatic imitation of emotional stimuli without controlling for potential confounders. The imitation impairments seen might therefore be secondary to other cognitive, motoric, or emotional deficits associated with the disorder. To overcome this issue, we used an automatic imitation paradigm with nonemotional stimuli to assess automatic imitation and the top-down modulation of imitation where participants were required to lift one of 2 fingers according to a number shown on the screen while observing the same or the other finger movement. In addition, we used a control task with a visual cue in place of a moving finger, to isolate the effect of observing finger movement from other visual cueing effects. Data from 33 patients (31 medicated) and 40 matched healthy controls were analyzed. Patients displayed enhanced imitation and intact top-down modulation of imitation. The enhanced imitation seen in patients may have been medication induced as larger effects were seen in patients receiving higher antipsychotic doses. In sum, we did not find an imitation impairment in schizophrenia. The results suggest that previous findings of impaired imitation in schizophrenia might have been due to other cognitive, motoric, and/or emotional deficits.

Is electroconvulsive therapy an evidence-based treatment for catatonia? A systematic review and meta-analysis

We aimed to review and discuss the evidence-based arguments for the efficacy of electroconvulsive therapy (ECT) in the treatment of catatonia. Randomized controlled trials (RCTs) and observational studies focusing on the response to ECT in catatonia were selected in PubMed, the Cochrane Library, Embase, ClinicalTrials.gov and Current Controlled Trials through October 2016 and qualitatively described. Trials assessing pre-post differences using a catatonia or clinical improvement rating scale were pooled together using a random effect model. Secondary outcomes were adverse effects of anesthesia and seizure. 564 patients from 28 studies were included. RCTs were of low quality and were heterogeneous; therefore, it was not possible to combine their efficacy results. An improvement of catatonic symptoms after ECT treatment was evidenced in ten studies (SMD = -3.14, 95% CI [-3.95; -2.34]). The adverse effects that were reported in seven studies included mental confusion, memory loss, headache, or adverse effects associated with anesthesia. ECT protocols were heterogeneous. The literature consistently describes improvement in catatonic symptoms after ECT. However, the published studies fail to demonstrate efficacy and effectiveness. It is now crucial to design and perform a quality RCT to robustly validate the use of ECT in catatonia.Prospero registration information: PROSPERO 2016: CRD42016041660.

The Differential Diagnosis and Treatment of Catatonia in Children and Adolescents

LEARNING OBJECTIVES

After participating in this activity, learners should be better able to:• Assess the etiologies associated with catatonia in children and adolescents• Evaluate the differential diagnosis of pediatric catatonia• Interpret the literature regarding the treatment of children and adolescents with catatonia OBJECTIVE: Pediatric catatonia is associated with many medical and psychiatric conditions. Mortality is high, and proper treatment can be lifesaving. Catatonia is increasingly recognized in pediatric populations, in which about 20% of cases are related to underlying medical conditions. To minimize morbidity, clinicians must rule out underlying disorders while simultaneously managing symptoms and causes. In our review we discuss (1) recommendations to aid rapid decision making, both diagnostic and therapeutic, (2) emergent conditions and management, (3) disorders associated with pediatric catatonia, including developmental, acquired, idiopathic, and iatrogenic etiologies, (4) available treatments, and (5) medicolegal considerations.

METHODS

Initial PubMed search without date constraints using MeSH terms related to pediatric catatonia, with subsequent searches on pertinent subtopics using PubMed and Google Scholar.

RESULTS

Pediatric catatonia is a dangerous but treatable neuropsychiatric condition. Psychiatrists need to be aware of differential diagnoses and to be able determine appropriate treatment within a short time frame. With prompt diagnosis and treatment, outcomes can be optimized.

CONCLUSION

Pediatric catatonia is underdiagnosed and requires rapid evaluation and management.

Prevalence and characteristics of catatonia on admission to an acute geriatric psychiatry ward

BACKGROUND

This study aims to describe the prevalence of catatonia in a population of older acute psychiatric inpatients according to different diagnostic criteria. Secondary objectives are: to compare the catatonic symptom profile, prevalence, and severity, in respect to the underlying aetiology, and to evaluate the association between catatonic and somatic comorbidity.

METHODS

The study included 106 patients admitted to an acute geriatric psychiatry ward. Catatonia was assessed using the Bush Francis Catatonia Rating Scale (BFCRS).

RESULTS

Catatonia was highly prevalent (n=42; 39.6%), even when using restrictive diagnostic criteria: Fink and Taylor (n=19; 17.9%) and DSM 5 (n=22; 20.8%). Depression was the most frequent psychiatric syndrome among catatonic patients (n=18; 42.8%). Catatonia was more frequent in depression (48.6%) and delirium (66.7%). Affective disorders showed a higher risk than psychotic disorders to develop catatonia (OR=2.68; 95% CI 1.09-6.61). This association was not statistically significant when controlling for dementia and geriatric syndromes. The most prevalent catatonic signs were excitement (64.3%), verbigeration (61.9%), negativism (59.5%), immobility/stupor (57.1%), and staring (52.4%).

CONCLUSIONS

Catatonia in older psychiatric inpatients was highly prevalent. Depression was the most common psychiatric syndrome among catatonic patients, and catatonia was more frequent in depression and mania, as well as in delirium. Affective disorders were associated with a higher risk of developing catatonia compared to psychotic disorders. Somatic and cognitive comorbidity played a crucial aetiological role in catatonia in this series.

Malignant Catatonia Warrants Early Psychiatric-Critical Care Collaborative Management: Two Cases and Literature Review

Malignant catatonia (MC) is a life-threatening manifestation which can occur in the setting of an underlying neuropsychiatric syndrome or general medical illness and shares clinical and pathophysiological features and medical comorbidities with the Neuroleptic Malignant Syndrome (NMS). The subsequent diagnosis and definitive therapy of MC are typically delayed, which increases morbidity and mortality. We present two cases of MC and review recent literature of MC and NMS, illustrating factors which delay diagnosis and management. When clinical features suggest MC or NMS, we propose early critical care consultation and stabilization with collaborative psychiatric management.

Brief episodes of non-specific psychosis later diagnosed as periodic catatonia

A 73-year-old woman was known to have discrete episodes of psychosis not otherwise specified that would require a brief admission to hospital and total remission following a short course of benzodiazepine or antipsychotic treatment. She had no underlying schizophrenic or affective disorder and was completely unimpaired in between episodes, which could last several years. She presented to us with psychotic symptoms but also noted to have many catatonic features, which were also present on previous presentations. Following failure with antipsychotic trials on this index presentation, she completely remitted with a short course of electroconvulsive therapy. We discuss the importance of identifying and treating catatonia and the lesser-known variant of periodic catatonia. Current presentations should always take into account the lifetime context of psychiatric illness. Rarely do patients with primary psychotic disorders not have any impairment or treatment in between episodes.

Assessing catatonia using four different instruments: Inter-rater reliability and prevalence in inpatient clinical population

BACKGROUND AND AIMS

The present study aimed to assess inter-rater reliability and prevalence of catatonia according to four diagnostic methods: Bush Francis Catatonia Rating Scale (BFCRS) both screening and complete scale, Braunig's Catatonia Rating Scale (CRS), ICD 10 and DSM5.

METHODS

For inter-rater reliability, different raters evaluated patients using the definitions provides by the four scales: BFCRS Screen and Total, CRS, ICD10 and DSM5. Kippendorff'α was used to compute the inter-rater reliability. Concordance between different systems was assessed using spearman correlation. Prevalence of catatonia was studied using the four definitions in a clinical sample of consecutive adult admissions in a psychiatry ward of a tertiary care hospital.

RESULTS

The inter-rater reliability was found to be good for BFCRS Total (α=0.779), moderate for DSM5 and BFCRS screen (α=0.575 and α=0.514 respectively) and low for CRS and ICD10 (α=0.111 and α=0.018 respectively). BFCRS Total and DSM5 definitions of catatonia had highest concordance (r_s=0.892 p<0.001). In the prevalence sample of consecutive hospital admissions, the prevalence was found to be highest with the definitions of BFCRS Screen and ICD 10 (10.3%, confidence intervals [CI] 3.9% to 16.7%), followed by BFCRS Total and DSM5 definitions 6.9%, CI 1.6% to 12.2%) and while CRS yielded the lowest prevalence rate (3.4%, CI 0% to 7.2%).

CONCLUSION

Different methods used to determine catatonia in the clinical sample yield different prevalence of this condition.

Catatonia vis-à-vis delirium: the significance of recognizing catatonia in altered mental status

BACKGROUND

Catatonia is seldom considered in evaluation of altered mental status (AMS) in medical settings. Furthermore, catatonia often meets delirium criteria due to incoherence, altered awareness and behavioral change. Catatonia may co-occur with or be preferentially diagnosed as delirium.

METHODS

We conducted a systematic literature review of MEDLINE, EMBASE and PsycINFO on the relationship between catatonia and delirium. We also juxtapose clinical features of these syndromes and outline a structured approach to catatonia evaluation and management in acute medical settings.

RESULTS

These syndromes share tremendous overlap: the historical catatonia-related terms "delirious mania" and "delirious depression" bespeak of literal confusion differentiating them. Only recently has evidence on their relationship progressed beyond case series and reports. Neurological conditions account for the majority of medical catatonia cases.

CONCLUSIONS

New-onset catatonia warrants a medical workup, and catatonic features in AMS may guide clinicians to a neurological condition (e.g., encephalitis, seizures or structural central nervous system disease). Lorazepam or electroconvulsive therapy (ECT) should be considered even in medical catatonia, and neuroleptics should be used with caution. Moreover, ECT may prove lifesaving in malignant catatonia. Further studies on the relationship between delirium and catatonia are warranted.

Catatonia in inpatients with psychiatric disorders: A comparison of schizophrenia and mood disorders

This study aimed to evaluate the symptom threshold for making the diagnosis of catatonia. Further the objectives were to (1) to study the factor solution of Bush Francis Catatonia Rating Scale (BFCRS); (2) To compare the prevalence and symptom profile of catatonia in patients with psychotic and mood disorders among patients admitted to the psychiatry inpatient of a general hospital psychiatric unit. 201 patients were screened for presence of catatonia by using BFCRS. By using cluster analysis, discriminant analysis, ROC curve, sensitivity and specificity analysis, data suggested that a threshold of 3 symptoms was able to correctly categorize 89.4% of patients with catatonia and 100% of patients without catatonia. Prevalence of catatonia was 9.45%. There was no difference in the prevalence rate and symptom profile of catatonia between those with schizophrenia and mood disorders (i.e., unipolar depression and bipolar affective disorder). Factor analysis of the data yielded 2 factor solutions, i.e., retarded and excited catatonia. To conclude this study suggests that presence of 3 symptoms for making the diagnosis of catatonia can correctly distinguish patients with and without catatonia. This is compatible with the recommendations of DSM-5. Prevalence of catatonia is almost equal in patients with schizophrenia and mood disorders.

A Case Report of Catatonia and Neuroleptic Malignant Syndrome With Multiple Treatment Modalities: Short Communication and Literature Review

We describe a case with complicated clinical presentations who was difficult to treat. We described the possible etiologies and differential diagnosis of neuroleptic malignant syndrome (NMS), catatonia, and infection, in details. This patient was also referred to neuro-intensive care unit for extensive workup and treatments by neurologist guidelines. In addition, we also used lorazepam-diazepam protocol and antipsychotics, but both failed to completely relieve her symptoms. She eventually responded to electroconvulsive therapy (ECT).A 60-year-old female patient with schizophrenia was diagnosed to suspected pneumonia, urinary tract infection, and retarded catatonia at first. The brain computed tomography revealed no significant finding. She developed NMS caused by the administration of low-dose quetiapine (200 mg) after carbamazepine was discontinued. The Francis-Yacoub NMS rating scale (F-Y scale) total score was 90. We utilized lorazepam-diazepam protocol and prescribed bromocriptine and amantadine, but NMS was not improved. Meanwhile, we arranged the brain magnetic resonance imaging to survey the physical problem, which revealed agenesis of septum pellucidum and dilated lateral ventricles. She was then transferred to the neuro-intensive care unit on the 15th hospital day for complete study. The results of cerebrospinal fluid study and electroencephalography were unremarkable. She was transferred back to psychiatric ward on the 21st hospital day with residual catatonic and parkinsonian symptoms of NMS, and the F-Y scale total score was 63. Finally, her residual catatonic condition that followed NMS got improved after 11 sessions of ECT. On the 47th hospital day, the F-Y scale total score was 9.This report underscores that the ECT is an effective treatment for a patient of NMS when other treatments have failed.

Movement disorders in catatonia

Catatonia is a complex neuropsychiatric syndrome characterised by a broad range of motor, speech and behavioural abnormalities. 'Waxy flexibility', 'posturing' and 'catalepsy' are among the well-recognised motor abnormalities seen in catatonia. However, there are many other motor abnormalities associated with catatonia. Recognition of the full spectrum of the phenomenology is critical for an accurate diagnosis. Although controlled trials are lacking benzodiazepines are considered first-line therapy and N-Methyl-d-aspartate receptor antagonists also appears to be effective. Electroconvulsive therapy is used in those patients who are resistant to medical therapy. An underlying cause of the catatonia should be identified and treated to ensure early and complete resolution of symptoms.

Electroconvulsive therapy in catatonic patients: Efficacy and predictors of response

Recent evidence favors the view of catatonia as an autonomous syndrome, frequently associated with mood disorders, but also observed in neurological, neurodevelopmental, physical and toxic conditions. From our systematic literature review, electroconvulsive therapy (ECT) results effective in all forms of catatonia, even after pharmacotherapy with benzodiazepines has failed. Response rate ranges from 80% to 100% and results superior to those of any other therapy in psychiatry. ECT should be considered first-line treatment in patients with malignant catatonia, neuroleptic malignant syndrome, delirious mania or severe catatonic excitement, and in general in all catatonic patients that are refractory or partially responsive to benzodiazepines. Early intervention with ECT is encouraged to avoid undue deterioration of the patient's medical condition. Little is known about the long-term treatment outcomes following administration of ECT for catatonia. The presence of a concomitant chronic neurologic disease or extrapyramidal deficit seems to be related to ECT non-response. On the contrary, the presence of acute, severe and psychotic mood disorder is associated with good response. Severe psychotic features in responders may be related with a prominent GABAergic mediated deficit in orbitofrontal cortex, whereas non-responders may be characterized by a prevalent dopaminergic mediated extrapyramidal deficit. These observations are consistent with the hypothesis that ECT is more effective in "top-down" variant of catatonia, in which the psychomotor syndrome may be sustained by a dysregulation of the orbitofrontal cortex, than in "bottom-up" variant, in which an extrapyramidal dysregulation may be prevalent. Future research should focus on ECT response in different subtype of catatonia and on efficacy of maintenance ECT in long-term prevention of recurrent catatonia. Further research on mechanism of action of ECT in catatonia may also contribute to the development of other brain stimulation techniques.

Treatment of a Prader-Willi Patient with Recurrent Catatonia

Prader-Willi is a genetic disorder characterized by neonatal hypotonia, hyperphagia, short stature, hypogonadism, and mental delay. This disorder can result from multiple mechanisms, most commonly a deletion of paternal chromosome 15, leaving a single maternally derived chromosome 15. Individuals who have a maternal uniparental disomy of chromosome 15 have a higher risk for developing psychosis compared to other forms of Prader-Willi. The following report details the treatment course of a 24-year-old female with Prader-Willi and recurrent catatonia. The patient initially had a positive lorazepam challenge test but subsequently failed treatment with benzodiazepines. She then received eight electroconvulsive therapy (ECT) treatments after which she showed improvement from initial catatonic state. However, the resolution in her symptoms did not follow a linear course but would show periods of improvement followed by a return of catatonic features. This case provides an example of the complexity of treatment of a patient with a genetic disorder and recurrent catatonia.
