A case report of a patient with Turner syndrome who develops catatonia secondary to psychotic symptoms.

RATIONALE: Turner syndrome (TS) is a genetic disorder associated with partial or complete monosomy X abnormalities; some patients may have a higher risk of psychiatric symptoms. Catatonia is associated with a wide range of life-threatening complications with complex pathogenesis; However, It very rare for patients with TS to develop psychotic symptoms and eventually progress to catatonia. This case report describes the diagnostic and therapeutic course of catatonia-associated TS. PATIENT CONCERNS: In this study, we report the case of a patient with TS who initially developed sudden hallucinations, delusions, and emotional instability, followed by catatonia. DIAGNOSES: The patient was diagnosed with: unspecified catatonia; TS. INTERVENTIONS: Treatment included administering a combination of esazolam injections and olanzapine tablets, placing a gastric tube and urinary catheter, and providing nutritional support. OUTCOMES: After treatment, the patient's hallucinations, delusions, and catatonia disappeared, with no residual sequelae, and social functioning returned to normal. LESSONS: For patients with TS who present with psychotic symptoms and catatonia, a comprehensive evaluation is necessary, and treatment with antipsychotics and benzodiazepines is effective.

Transient Fever Response After ECT in a Patient with Catatonic Schizophrenia: A Case Report. / Katatonik Sizofreni Hastasinda EKT Sonrasi Ortaya Çikan Geçici Ates Yaniti: Olgu Sunumu.

Electroconvulsive therapy (ECT) is an effective and safe treatment method for many psychiatric disorders. In general medical practice, ECT may cause side effects as most other treatment methods do. Headache, myalgia, nausea, vomiting, confusion, anterograde amnesia are common side effects of electroconvulsive therapy. Fever; in addition to general medical conditions such as infection, malignancy, connective tissue diseases, drug treatments, malignant hyperthermia, convulsions, it can also occur due to conditions such as neuroleptic malignant syndrome (NMS), serotonin syndrome, catatonia, malignant catatonia, which are frequently encountered in psychiatry clinics. In the literature, transient fever response due to electroconvulsive therapy application have been described, albeit rarely. Although there are many proposed mechanisms for the emergence of a fever response, regardless of its cause, it is still not understood why some fever responses occur. In this article, we present the differential diagnosis of the fever response, possible causes, and the mechanisms that may reveal the secondary fever response to electroconvulsive therapy in a case with a diagnosis of catatonic schizophrenia, who developed a fever response during electroconvulsive therapy sessions and no fever response was observed at times other than electroconvulsive therapy sessions. In this case, postictal benign fever response associated with electroconvulsive therapy was considered after excluding other medical conditions that may cause a fever response after electroconvulsive therapy.

Neurodevelopmental Disorders Including Autism Spectrum Disorder and Intellectual Disability as a Risk Factor for Delayed Diagnosis of Catatonia.

OBJECTIVE: Catatonia is a distinct and severe medical syndrome comprising motor, somatic, and psychiatric symptoms that is reported in upwards of 17% of young patients with autism spectrum disorders. Clinical experience indicates catatonia is often under-recognized in this clinical population. Here we characterize the clinical presentation of catatonia in patients with and without neurodevelopmental disorders (NDDs) including autism, including the time from symptom onset to diagnosis of catatonia. METHOD: Retrospective chart review of electronic medical records at a large, academic pediatric medical center identified 113 pediatric and young adult patients with a charted history of catatonia, as identified by an encounter diagnosis or problem list entry between September 2017 and September 2021. Workup, treatments, and diagnoses (psychiatric, neurodevelopmental, and genetic) were identified. RESULTS: We observed a clear and substantial delay in identification of catatonia in those with NDDs (diagnosis after 330 days for those without psychosis) compared with neurotypical patients (∼16 days). Psychiatry involvement was associated with shorter delays. CONCLUSION: Intellectual disability and autism are risk factors for significantly delayed diagnosis of catatonia. It is unknown whether delayed diagnosis contributes to the difficulty in treating catatonia in this patient population or whether the treatment difficulties relate instead to differential and ongoing biological mechanisms and underlying encephalopathy. Overall, these findings highlight the importance of increased recognition of catatonia symptoms in patients with NDDs and suggest early referral to psychiatric specialists may shorten the delay to diagnosis.

Thought Blocking as a Manifestation of Catatonia: A Case Report.

ABSTRACT: Catatonia is an underrecognized disorder that has been widely described as a psychomotor syndrome, with little emphasis on its thought and cognitive dimensions. The current Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, Text Revision describes only motor and behavioral presentations, whereas a few catatonia scales describe only one form of thought disorders, which is thought perseveration. Thought blocking, a disorder of the thought process, is characterized by regular interruptions in the thought stream. It was described by several scholars as a sign of schizophrenia, with few reports describing thought blocking in association with catatonia. In this article, we describe the course of a patient with bipolar I disorder who presented with catatonia and demonstrated thought blocking. Her catatonic symptoms and thought blocking improved with the addition of lorazepam, recurred upon lorazepam discontinuation, and improved with resumption of lorazepam, demonstrating a clear on/off phenomenon. This report highlights the importance of recognizing thought and cognitive manifestations of catatonia, as it can enhance recognition and improve treatment.

Catatonia in the peripartum: A cohort study using electronic health records.

BACKGROUND: Due to limited existing literature available on the presentation and treatment of catatonia in the peripartum, this retrospective descriptive cohort study aimed to examine demographic data, catatonic features, diagnoses pre- and post-catatonic episodes, treatment and the presence of obstetric complications. METHODS: Individuals with catatonia were identified in a previous study using anonymised electronic healthcare records from a large mental health trust in South-East London. The presence of features from the Bush-Francis Catatonia Screening Instrument was coded by the investigators and longitudinal data were extracted from structured fields and free text. RESULTS: 21 individuals were identified from the larger cohort, each of whom experienced one episode of catatonia in the postpartum period, and all had had an inpatient psychiatric admission. 13 patients (62 %) presented after their first pregnancy and 12 (57 %) experienced obstetric complications. 11 (53 %) attempted breastfeeding and 10 (48 %) received a diagnosis of a depressive disorder following the episode of catatonia. The majority presented with immobility or stupor, mutism, staring and withdrawal. All were treated with antipsychotics and 19 (90 %) received benzodiazepines. CONCLUSIONS: This study suggests that signs and symptoms of catatonia during the peripartum are similar to other catatonic presentations. However, the postpartum may be a period of high risk for catatonia and obstetric factors, such as birth complications, may be relevant.

Electroconvulsive therapy for catatonia in anti-NMDA receptor encephalitis: A case series.

BACKGROUND: Anti-NMDAR encephalitis is the most common cause of immune-mediated catatonia. CASE SERIES: Three females presented with neuropsychiatric symptoms and were empirically treated with first-line immunotherapy and ovarian teratoma resection for suspected autoimmune encephalitis, preceding diagnostic confirmation via NMDAR antibody positivity. They required escalating large doses of benzodiazepines for refractory malignant catatonia resulting in ICU level care. ECT treatments were initiated, and patients were gradually noted to have clinical improvement as was measured by the Bush-Francis Catatonia Rating Scale. CONCLUSIONS: Clinicians should recognize catatonia among patients with suspected anti-NMDAR encephalitis and consider the early implementation of ECT into treatment algorithms.

Catatonia as the Presentation of Encephalopathy Associated With Autoimmune Thyroiditis: A Case Report and Literature Review.

Encephalopathy can be associated with autoimmune disorders such as autoimmune thyroiditis, and it can present with a wide range of neuropsychiatric manifestations. However, it rarely presents with catatonia. We present the case of a middle-aged female with Hashimoto's thyroiditis presenting with catatonia. A literature review of previous similar cases highlighting significant points is also included. A 48-year-old female presented to the emergency department with catatonic symptoms that had worsened over the previous 5 days. A similar condition was reported to have occurred and resolved spontaneously 3 months earlier. On examination, the patient appeared uncooperative and unresponsive. She showed typical symptoms of catatonia, with a score of 21 points on the Bush-Francis Catatonia Rating Scale. Routine tests were within normal ranges except for an elevated level of C-reactive protein and an elevated erythrocyte sedimentation rate. Computed tomography, magnetic resonance imaging, and cerebrospinal fluid analysis were all normal. An electroencephalogram showed diffuse delta-theta range slowing with no epileptiform discharges. Lorazepam was initiated but did not control the catatonic symptoms. Re-evaluation revealed thyroid swelling and elevated levels of thyroperoxidase antibodies. IV methylprednisolone was therefore initiated and produced complete resolution of the catatonic symptoms in 4 hours. The patient was discharged and prescribed prednisone 1 mg/kg daily. At follow-up, the patient continued to show complete resolution of the catatonic symptoms. It is noteworthy that the patient developed hypothyroidism 6 months after this catatonic episode for which levothyroxine 50 mcg/d was prescribed. Encephalopathy associated with autoimmune thyroiditis can initially present with catatonic symptoms in euthyroid cases. The mainstay of treatment is steroids which result in complete resolution of the catatonic symptoms.

The Neuropsychiatric Side of Cerebral Venous Thrombosis: A Case of Delirium and Catatonia.

We report a patient with cerebral venous thrombosis who initially presented with psychosis and who then progressed to delirium and catatonia within a few days. Upon treatment and resolution of the thrombosis, she presented complete remission of the psychiatric disturbances. This case highlights a specific neuropsychiatric presentation of cerebral venous thrombosis involving psychosis, catatonia, and delirium, which, to our best knowledge, has not been reported in the neurological or psychiatric literature. However, it reminds us of mental status and behavioral abnormalities which are not infrequent features of cerebral venous thrombosis. This leads to a discussion regarding the psychopathology, etiology, and pathophysiology of the case.

[Periodic catatonia in schizophrenia spectrum disorders]. / Periodicheskaya katatoniya pri rasstroistvakh shizofrenicheskogo spektra.

OBJECTIVE: Typological differentiation of periodic catatonia in schizophrenia and schizophrenia spectrum disorders (SSD), in particular, schizoaffective disorder. MATERIAL AND METHODS: Seventy-four patients with the verified diagnosis of schizophrenia and SSD (ICD-10 items F20, F21) were studied. The clinical, psychometric (BFCRS, SANS) and statistical methods were used. Clinical and psychometric study of seizures of periodic catatonia was carried out at the following stages: 1) manifestation of a seizure; 2) the maximum severity of psychopathological disorders. Also, at the end of the seizure, an additional assessment of the severity of negative symptoms was carried out using the SANS. RESULTS: Three forms of periodic catatonia have been identified: hypokinetic, parakinetic, multikinetic. Clinical distinguishing indicators of periodic catatonia seizurs have been established (protracted - two-stage - form of seizures; the phenomenon of «secondary catatonia¼). The psychometric study revealed significant differences between the variants of periodic catatonia seizures in terms of the severity of motor phenomena (at both stages of the seizure) and negative disorders. BFCRS scores at the first stage of seizures were as follows: hypokinetic - 9.7±0.4; parakinetic - 12.8±0.9; multikinetic - 32.3±1.6 (the differences were found between 1 and 2 (p<0.05); between 1 and 3, as well as 2 and 3 (p<0.01)). BFCRS scores at the second stage of seizures were 12.1±0.8; 19.9±1.2 and 47.7±1.9, respectively,with the differences between 1 and 2 (p<0.05); between 1 and 3, and also 2 and 3 (p<0.01). The scores on the SANS anhedonia-asociality subscale were 1.9±0.2 for hypokinetic; 2.3±0.3 for parakinetic and 3.2±0.2 for multikinetic with the differences between 1 and 2, 1 and 3, 2 and 3 (p<0.01). CONCLUSION: Periodic catatonia is the clinical entity that includes a complex of progressively worsening seizures, the psychopathological systematics of which takes into account the clinical structure of motor disorders, their affiliations with positive and negative dimensions, and functional activity.

Clozapine for treatment refractory catatonia in individuals with autism spectrum disorder: a retrospective chart review study.

BACKGROUND: Catatonia is increasingly recognized in individuals with autism spectrum disorder (ASD). Empirical data on treating catatonia in this population are limited. The purpose of this study is to provide naturalistic data on the use of clozapine for the treatment of catatonia in patients with ASD. RESEARCH DESIGN AND METHODS: Medical records of 12 individuals with ASD and catatonia who received treatment with clozapine were reviewed. Treatment response to clozapine was rated by assigning a retrospective Clinical Global Impression Improvement scale (CGI-I) score. RESULTS: Mean (SD) and median (IQR) age at initiation of clozapine treatment were 22.1 (7.7) and 20.4 (9.7) years, with a range of 10-39 years. Eleven of the 12 patients had received treatment with lorazepam prior to initiating clozapine and 9 of the 12 patients received concomitant treatment with lorazepam and clozapine. Eleven of the 12 patients (92%; 95% CI: 65%, 99%) responded to clozapine. All 12 patients remained on clozapine at the time of their most recent clinical note. All 12 patients (100%; 95% CI: 76%, 100%) experienced one or more adverse events, the most common of which was sedation (n = 11, 92%). CONCLUSIONS: Overall, clozapine was associated with a high response rate for the treatment of catatonia in patients with ASD. These naturalistic data support the use of clozapine for the treatment of catatonia in patients with ASD for whom lorazepam is either ineffective or partially effective.

Immune-inflammatory responses and pulmonary embolism in Catatonia: A report of two cases.

Venous thromboembolism (VTE) comprises pulmonary embolism (PE) and deep vein thrombosis (DVT). PE, as the most severe manifestation of VTE, can cause increased mortality in patients with mental disorders. Here we describe two cases of young male patients with catatonia who developed PE and DVT during their hospital stay. We also discuss the possible pathogenesis, with a focus on immune and inflammatory mechanisms.

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).
