Catatonia is an undertreated and underdiagnosed neuropsychiatric syndrome whose prognosis is benign if treated early, thus avoiding possible complications and compromising the health of patients. The latest epidemiological studies indicate a prevalence of catatonia of 9.2%, being frequent in medical pathologies (especially neurological ones), as well as in psychiatric pathologies. The use of validated scales is recommended for its diagnosis, to be able to measure the severity and response to treatment. Once catatonia has been identified, it is necessary to perform a protocolized diagnostic study of the underlying aetiology («Catatonia Workup»). Treatment of choice is benzodiazepines and electroconvulsive therapy. In recent years, new therapeutic alternatives such as non-invasive transcranial magnetic stimulation have emerged. In this review we propose several initiatives to promote the dissemination and knowledge of catatonia in the clinical setting., (Copyright © 2021 Elsevier España, S.L.U.

Objective: To ascertain the clinical characteristics of anti-NMDA receptor encephalitis (NMDARE) in older patients., Method: A systematic literature review using PubMed and Scopus of all published case reports of NMDARE was undertaken, from database inception to June 2020. From this, cases reporting on patients older than 65 years of age and whose diagnosis was confirmed by the presence of anti-NMDAR antibodies in CSF were selected., Results: 23 case reports fulfilling the study's criteria were found. Median age was 70.1 years (range 65-84), fourteen were female (60.9%), and mostly presented with acute behavioral and cognitive changes (95.7%). Atypical psychosis occurred in eleven patients (47.8%) with a sudden onset and fluctuating clinical pattern of delusions (39.1%), hallucinations (30.4%), and motility disturbances (34.8%) including catatonia (17.4%). Nine patients presented with seizures (39.1%). Pleocytosis in CSF (>5 WBC) was described in twelve cases (52.2%). Eleven cases (47.8%) had abnormal brain magnetic resonance imaging (MRI) scans with limbic inflammatory lesions. Thirteen patients had an abnormal EEG (56.5%)., Conclusion: NMDARE should be included in the differential diagnosis of older patients who present with new psychiatric episodes, especially when characterized by sudden onset psychotic polymorphic symptomatology, fluctuating course with marked cognitive decline, and with catatonic features., (Copyright © 2021 Elsevier Inc.

Objective: Catatonic stupor has been linked to extreme fear. Whether the underlying phenomenology of every catatonic dimension is intense anxiety or fear remains unknown., Methods: One hundred and six patients aged ≥64 years were assessed for catatonia and clinical variables during the first 24 hours of admission. Two-sample t test were used to test for group differences. A principal component analysis was developed. Analysis of variance was performed to assess for differences in the diagnostic groups. Correlation coefficients were used to examine the association between catatonic dimensions and psychopathological variables., Results: There were statistically significant differences between catatonic and non-catatonic patients in the Hamilton and NPI scores. The three factor-model accounted for 52.23% of the variance. Factor 1 loaded on items concerned with "excitement," factor 2 on "inhibition" items, and factor 3 on "parakinetic" items. There was a significant effect for factor 1 (F [5.36] = 2.83, P = .02), and not significant for factor 2 and factor 3. Compared with patients with depression, patients with mania scored significantly higher on factor "excitement" (P < .05). Factor 2 showed a moderate correlation with Hamilton total score (r = .346, P = .031) and Hamilton psychic score (r = .380, P = .017)., Conclusions: Catatonic patients experienced more anxiety and hyperactivity. A three-factor solution provided best fit for catatonic symptoms. Patients with mania scored highest on Excitement, patients with depression on Inhibition, and patients with schizophrenia on Parakinetic. The main finding in this study was a positive moderate correlation between the Hamilton psychic score and the Inhibition factor score, meaning that not every catatonic dimension is associated to intense anxiety., (© 2020 John Wiley & Sons Ltd.) more...

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., (Copyright © 2017 Elsevier Inc. All rights reserved.) more...
