Objective: This article aims to describe the adaptation and translation process of the Bush-Francis Catatonia Rating Scale (BFCRS) and its reduced version, the Bush-Francis Catatonia Screening Instrument (BFCSI) for Brazilian Portuguese, as well as its validation. Methods: Semantic equivalence processes included four steps: translation, back translation, evaluation of semantic equivalence and a pilot-study. Validation consisted of simultaneous applications of the instrument in Portuguese by two examiners in 30 catatonic and 30 non-catatonic patients...

Catatonia is a psychomotor syndrome that has been reported to occur in more than 10% of patients with acute psychiatric illnesses. Two subtypes of the syndrome have been identified. Catatonia of the retarded type is characterized by immobility, mutism, staring, rigidity, and a host of other clinical signs. Excited catatonia is a less common presentation in which patients develop prolonged periods of psychomotor agitation. Once thought to be a subtype of schizophrenia, catatonia is now recognized to occur with a broad spectrum of medical and psychiatric illnesses, particularly affective disorders...

Electroconvulsive therapy (ECT) is one of the oldest and best treatments for severe mental illness. A safe and highly effective option for treatment-resistant mood disorders, ECT can be a lifesaving treatment for people suffering from catatonia and acute suicidality. Less recognized are the benefits of ECT in the treatment of primary psychotic disorders, Parkinson's disease, and status epilepticus. Evidence from multisite clinical trials in the past decade shows an evolving standard for the delivery of ECT to achieve and maintain remission and quality of life...

BACKGROUND: Psychosis is a common presenting feature in antibody-mediated encephalitis, for which prompt recognition and treatment usually leads to remission. We aimed to investigate whether people with circumscribed schizophrenia-like illnesses have such antibodies-especially antibodies against the N-methyl-D-aspartate receptor (NMDAR)-more commonly than do healthy controls. METHODS: We recruited patients aged 14-35 years presenting to any of 35 mental health services sites across England with first-episode psychosis, less than 6 weeks of treatment with antipsychotic medication, and a score of 4 or more on at least one selected Positive and Negative Syndrome Scale (PANSS) item...

A woman in her 60s with a history of hepatitis C with cirrhosis and major depressive disorder with psychotic features was admitted to the inpatient psychiatric unit for suicidal ideation. She was initially treated with a combination of sertraline and paliperidone. The paliperidone was subsequently changed to risperidone and ultimately to olanzapine. She developed worsening mental status and was then treated for catatonia with benzodiazepines. Over 2 days, her mental status continued to worsen and she developed fever and tachycardia...

Although commonly linked to psychiatric disorders, catatonia is frequently identified secondary to neurological and general medical conditions (GMCs). The present study aimed to characterize the diagnostic workup of cases of catatonia in a general hospital setting. The authors performed a retrospective chart review of 54 cases of catatonia, over 3 years. Clinical suspicion of comorbid delirium was the strongest predictor of a more thorough general medical workup. Attribution of catatonia to a psychiatric etiology was associated with significantly less diagnostic workup...

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...

OBJECTIVES: There are no studies investigating physicians' knowledge of catatonia. The authors aimed to assess and increase physicians' awareness of catatonia. METHODS: A survey with clinical questions about catatonia was administered, followed by a brief online teaching module about catatonia and a post-education survey. RESULTS: Twenty-one psychiatry residents (response rate, 70%) and 36 internal medicine residents (response rate, 34%) participated in the pre-education survey...

BACKGROUND: The categories of functional psychoses build on views of influential professionals. There have long been four main categories - affective, schizophrenic, schizoaffective/cycloid/reactive/polymorphic, and delusional/paranoid psychoses. The last three are included in "psychotic disorders". However, this dichotomy and the distinctions between categories may have been over-estimated and contributed to lack of progress.

Existing standardized diagnostic interviews (SDIs) were designed for researchers and produce mainly categorical diagnoses. There is an urgent need for a clinician-administered tool that produces dimensional measures, in addition to categorical diagnoses. The Standard for Clinicians' Interview in Psychiatry (SCIP) is a method of assessment of psychopathology for adults. It is designed to be administered by clinicians and includes the SCIP manual and the SCIP interview. Clinicians use the SCIP questions and rate the responses according to the SCIP manual rules...

Aiming to identify new antipsychotic lead-compounds, our group has been working on the design and synthesis of new N-phenylpiperazine derivatives. Here, we characterized LASSBio-1422 as a pharmacological prototype of this chemical series. Adult male Wistar rats and CF1 mice were used for in-vitro and in-vivo assays, respectively. LASSBio-1422 [1 and 5 mg/kg, postoperatively (p.o.)] inhibited apomorphine-induced climbing as well as ketamine-induced hyperlocomotion (1 and 5 mg/kg, p.o.), animal models predictive of efficacy on positive symptoms...

BACKGROUND: Movement disorder emergencies include any movement disorder which develops over hours to days, in which failure to appropriately diagnose and manage can result in patient morbidity or mortality.Movement disorder emergencies include acute dystonia: sustained or intermittent muscle contractions causing abnormal, often repetitive, movements. Acute dystonia is a serious challenge for emergency room doctors and neurologists, because of the high probability of misdiagnosis, due to the presence of several mimickers including partial seizures, meningitis, localized tetanus, serum electrolyte level abnormalities, strychnine poisoning, angioedema, malingering, catatonia, and conversion...

Catatonia is a psychomotor syndrome that not only frequently occurs in the context of schizophrenia but also in other conditions. The neural correlates of catatonia remain unclear due to small-sized studies. We therefore compared resting-state cerebral blood flow (rCBF) and gray matter (GM) density between schizophrenia patients with current catatonia and without catatonia and healthy controls. We included 42 schizophrenia patients and 41 controls. Catatonia was currently present in 15 patients (scoring >2 items on the Bush Francis Catatonia Rating Scale screening)...

A 42-year-old Japanese woman with a 10-year history of schizophrenia was admitted due to a disturbance in consciousness that met the diagnostic criteria for both neuroleptic malignant syndrome (NMS) and malignant catatonia. Despite systemic supportive treatments, the catatonic symptoms preceding autonomic symptoms persisted. The symptoms improved after lorazepam administration, leading to a retrospective diagnosis of malignant catatonia. Catatonia is thought to be caused by a dysfunction of ganmma-aminobutyric acid type A receptors in the cortico-cortical networks of the frontal lobes, which causes hypoactivity of the dopaminergic transmission in the subcortical areas...

Functional coma - here defined as a prolonged motionless dissociative attack with absent or reduced response to external stimuli - is a relatively rare presentation. In this chapter we examine a wide range of terms used to describe states of unresponsiveness in which psychologic factors are relevant to etiology, such as depressive stupor, catatonia, nonepileptic "pseudostatus," and factitious disorders, and discuss the place of functional or psychogenic coma among these. Historically, diagnosis of functional coma has sometimes been reached after prolonged investigation and exclusion of other diagnoses...
