A case report: Catatonic symptoms secondary to systemic lupus erythematosus with multiple infections: neuropsychiatric or "mimickers?"

RATIONALE: Systemic lupus erythematosus (SLE) is frequently accompanied by neuropsychiatric (NP) manifestations. However, typical symptoms of catatonia are uncommon. Neuropsychiatric SLE or its "mimickers" may cause NP symptoms, making differential diagnosis a significant challenge in clinical practice. PATIENT CONCERNS: A 68-year-old female with SLE was hospitalized for edema, lung infection, and recurrent fungal mouth ulcers after multiple courses of cortisol and immunosuppressive therapy. Five days after admission, stupor, immobility, mutism, and rigidity were observed. DIAGNOSIS: "Mimickers": catatonic disorder due to a general medical condition. INTERVENTION: Initially, relevant laboratory tests, imaging studies, and the disease activity index score were performed. A survey of the causes of the disease was conducted among the patient's relatives. Subsequently, we discontinued moxifloxacin, corticosteroids, fluconazole, and other medications and inserted a gastric tube for nutritional support. During this process, traditional Chinese medicine and acupuncture have been utilized. OUTCOMES: After 3 days, the patient recovered and only complained of fatigue. CONCLUSION: When SLE presents with NP symptoms, it is essential to make a correct diagnosis in order to guide appropriate treatment by actively searching for inducers and clinical, laboratory, and neuroradiological characteristics that can aid in the differential diagnosis. When treatment options are limited, it can be beneficial to try a variety of combination strategies, such as traditional Chinese medicine and acupuncture.

Characterisation and outcome of neuropsychiatric symptoms in patients with anti-NMDAR encephalitis.

BACKGROUND: Encephalitis due to anti-N-methyl-D-aspartate receptor antibodies (ANMDARE) is the most frequent immune-mediated encephalitis. It is distinguished by the subacute onset of neuropsychiatric symptoms. OBJECTIVE: To evaluate the characteristic neuropsychiatric symptoms and their outcome in patients diagnosed with ANMDARE. METHODS: This was a prospective, longitudinal study in patients with a diagnostic suspicion of ANMDARE that presented to the National Institute of Neurology from March 2018 to February 2019. A comparative analysis of two groups (positive N-methyl-D-aspartate receptor [NMDAR] vs. negative NMDAR antibodies in cerebrospinal fluid [CSF]) was done on admission and at discharge. Neuropsychiatric systematic assessments included the Neuropsychiatric Inventory Questionnaire, the Bush Francis Catatonia Rating Scale, the Confusion Assessment Method Severity, the Montreal Cognitive Assessment, and the Overt Agitation Severity Scale. RESULTS: 24 individuals were analysed: 14 had positive NMDAR antibodies, and 10 had negative NMDAR antibodies in CSF. On admission, agitation/aggression, euphoria/exaltation, and disinhibition were more common in patients with positive antibodies. Excited catatonia and delirium were diagnosed more frequently in patients with positive antibodies. At discharge, there was an important decrease in neuropsychiatric symptoms, but substantial cognitive impairment remained. The mean hospitalisation length was 41.71 (SD 39.33) days for patients with definitive ANMDARE (p 0.259). CONCLUSIONS: Neuropsychiatric symptoms profile in ANMDARE was associated with the early onset of euphoria/exaltation and disinhibition, accompanied by marked psychomotor agitation. When ANMDARE was suspected, the presence of excited-type catatonia and delirium showed a tendency to predict definitive ANMDARE. At discharged, most patients recovered from catatonia, delirium, and psychosis, but marked cognitive symptoms, anxiety, and depression persisted at discharge.

Multimodal Magnetic Resonance Imaging Data Fusion Reveals Distinct Patterns of Abnormal Brain Structure and Function in Catatonia.

Catatonia is a nosologically unspecific syndrome, which subsumes a plethora of mostly complex affective, motor, and behavioral phenomena. Although catatonia frequently occurs in schizophrenia spectrum disorders (SSD), specific patterns of abnormal brain structure and function underlying catatonia are unclear at present. Here, we used a multivariate data fusion technique for multimodal magnetic resonance imaging (MRI) data to investigate patterns of aberrant intrinsic neural activity (INA) and gray matter volume (GMV) in SSD patients with and without catatonia. Resting-state functional MRI and structural MRI data were collected from 87 right-handed SSD patients. Catatonic symptoms were examined on the Northoff Catatonia Rating Scale (NCRS). A multivariate analysis approach was used to examine co-altered patterns of INA and GMV. Following a categorical approach, we found predominantly frontothalamic and corticostriatal abnormalities in SSD patients with catatonia (NCRS total score ≥ 3; n = 24) when compared to SSD patients without catatonia (NCRS total score = 0; n = 22) matched for age, gender, education, and medication. Corticostriatal network was associated with NCRS affective scores. Following a dimensional approach, 33 SSD patients with catatonia according to Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision were identified. NCRS behavioral scores were associated with a joint structural and functional system that predominantly included cerebellar and prefrontal/cortical motor regions. NCRS affective scores were associated with frontoparietal INA. This study provides novel neuromechanistic insights into catatonia in SSD suggesting co-altered structure/function-interactions in neural systems subserving coordinated visuospatial functions and motor behavior.

Association between catatonia and levels of hair and serum trace elements and minerals in autism spectrum disorder.

The objective of the study was to investigate the association between catatonia in autism spectrum disorder (ASD) and the levels of hair and serum trace elements and minerals in children with ASD. The levels of hair and serum trace elements and minerals of boys suffering from ASD with (n = 30) and without (n = 30) catatonia, as well as 30 age- and sex-matched neurotypical controls were assessed using ICP-MS. Hair calcium (Ca) and selenium (Se) levels were lower in ASD patients as compared to the controls. Hair mercury (Hg) levels in ASD patients were more than 3-fold and 2-fold higher as compared to the controls and children with catatonia in ASD. Hair iodine (I) and manganese (Mn) were the lowest and the highest in ASD + Catatonia, respectively. Serum aluminium (Al) and cadmium (Cd) levels in healthy controls were significantly higher in comparison to the patients of both groups. Serum chromium (Cr), copper (Cu) levels were significantly increased in patients with ASD and catatonia, whereas vanadium (V) levels were elevated in patients both with and without catatonia. Multiple regression analysis demonstrated that hair Hg and serum Al and Cd levels were negatively associated with catatonia in ASD in crude and adjusted models. Although the etiology of catatonia in ASD is unclear, the obtained data demonstrate that catatonic symptoms in ASD may be at least partially mediated by altered trace element levels. Further studies are required to elucidate the role of trace elements in the potential signaling mechanisms of catatonia.

Persistent catatonia following epileptic seizures: a case report and systematic literature search.

BACKGROUND: Catatonia is frequently associated with mood and psychotic disorders as well as with general medical conditions, especially with seizures. In the case of the latter, catatonia mostly resolves when the seizures respond to the anticonvulsive treatment. We report, to our knowledge, the first case of a patient without affective or psychotic disorder, who developed catatonia in the postictum and whose catatonia did not resolve with anticonvulsive treatment, but did so with lorazepam. CASE PRESENTATION: We describe a 36-year-old man, with no psychiatric history, except for a possible disorder in the use of cannabis, who developed catatonia after epileptic seizures. The catatonia did not respond to the anticonvulsant therapy, but did so to lorazepam 17 mg/d. Lorazepam could be tapered slowly and stopped without reemergence of catatonic signs. CONCLUSION: Catatonia should be part of the differential diagnosis in patients with bradyphrenia and/or remarkable postictal behavior. This report shows that lorazepam should be taken into consideration (before moving to ECT), in cases of unresolved catatonia, even if the seizures are reduced with anticonvulsants.

Aberrant Hyperconnectivity in the Motor System at Rest Is Linked to Motor Abnormalities in Schizophrenia Spectrum Disorders.

Motor abnormalities are frequently observed in schizophrenia and structural alterations of the motor system have been reported. The association of aberrant motor network function, however, has not been tested. We hypothesized that abnormal functional connectivity would be related to the degree of motor abnormalities in schizophrenia. In 90 subjects (46 patients) we obtained resting stated functional magnetic resonance imaging (fMRI) for 8 minutes 40 seconds at 3T. Participants further completed a motor battery on the scanning day. Regions of interest (ROI) were cortical motor areas, basal ganglia, thalamus and motor cerebellum. We computed ROI-to-ROI functional connectivity. Principal component analyses of motor behavioral data produced 4 factors (primary motor, catatonia and dyskinesia, coordination, and spontaneous motor activity). Motor factors were correlated with connectivity values. Schizophrenia was characterized by hyperconnectivity in 3 main areas: motor cortices to thalamus, motor cortices to cerebellum, and prefrontal cortex to the subthalamic nucleus. In patients, thalamocortical hyperconnectivity was linked to catatonia and dyskinesia, whereas aberrant connectivity between rostral anterior cingulate and caudate was linked to the primary motor factor. Likewise, connectivity between motor cortex and cerebellum correlated with spontaneous motor activity. Therefore, altered functional connectivity suggests a specific intrinsic and tonic neural abnormality in the motor system in schizophrenia. Furthermore, altered neural activity at rest was linked to motor abnormalities on the behavioral level. Thus, aberrant resting state connectivity may indicate a system out of balance, which produces characteristic behavioral alterations.

Anti-NMDA receptor encephalitis: psychiatric presentation and diagnostic challenges from psychosomatic medicine perspective.

We describe two cases of confirmed anti-NMDA receptor encephalitis; one patient initially presented with a clinical picture that resembled delirium and later appeared to present with a conversion reaction and the second patient presented with a first psychotic break followed by the clinical picture of neuroleptic malignant syndrome with catatonia. Neither patient had a previous history of psychiatric illness or recreational drug use. These cases illustrate the diagnostic and treatment challenges associated with this neuropsychiatric condition and underscore the role of psychosomatic medicine psychiatrists in diagnosing anti-NMDA receptor encephalitis.

A case of catatonia resembling frontotemporal dementia and resolved with electroconvulsive therapy.

We describe a case of catatonia in a 51-year-old man in whom the catatonic symptoms could not be distinguished from symptoms of frontotemporal dementia (FTD) until they were resolved with electroconvulsive therapy (ECT). When it is difficult to distinguish between catatonia and FTD in patients with frontal dysfunction associated with frontal lobe atrophy, we believe that sequential administration of benzodiazepines and ECT is important for therapeutic diagnosis because the risk of missing a diagnosis of catatonia outweighs the risks associated with administration of benzodiazepines and/or ECT.

[Malignant catatonia as paradigm of neuropsychiatric disease]. / La catatonía maligna como paradigma de enfermedad neuropsiquiátrica.

Catatonia is a large neuropsychiatric syndrome with multiple etiologies (psychiatric disorder, cerebral structural lesion, systemic disease, secondary to drugs and toxic agents) and varied clinical manifestations (cognitive and behavioral disorders, motor and speech disorders and vegetative disorders). The presence of disautonomy means a situation having vital risk, that requires immediate therapeutic intervention. A 22 year old woman was admitted due to a picture of stupor, fever, maintained postures, rigidity, seizures and tachycardia and hypertension episodes; this picture initiated four weeks earlier, with psychotic and affective symptoms and she slowly developed speech and motor activity impairment. Initially, she had been treated with neuroleptics, anticholinergics and antidepressants. The CT, MRI and CSF studies were normal. The EEG revealed diffuse slow waves and right frontotemporal paroxystic activity Laboratory determinations showed elevation of CK, coinciding with the vegetative disorder phase. The picture resolved progressively in two months, after receiving 19 sessions of electroshock therapy. In all the patients, and above all in those who receive neuroleptics, with symptoms suggesting catatonia, the presence of disautonomy should be considered as an alarm situation, which would make it necessary to discontinue the neuroleptics and to adopt special control. Electroshock therapy is the most effective therapeutic option in the situation of malignant catatonia.
