Catatonia associated with pediatric postoperative cerebellar mutism syndrome.

OBJECTIVE: To ascertain the presence of catatonia in cases of pediatric postoperative cerebellar mutism syndrome (PPCMS). METHOD: A systematic review of PPCMS case reports of patients aged 0-17 years with sufficient clinical information to extract catatonic phenomena was undertaken following PRISMA guidelines. Standardized catatonia rating scales were applied to selected cases retrospectively to ascertain whether diagnostic criteria for catatonia were met. A case known to the authors is also presented. RESULTS: Two hundred twenty-one suitable full-text articles were identified. Following screening and application of inclusion criteria, 51 articles were selected plus seven more from their references, reporting on 119 subjects. All cases met Bush and Francis (BF) diagnostic criteria for catatonia, 92.5% Pediatric Catatonia Rating Scale (PCRS), 52.9% ICD-11, and 44.5% DSM-5. All patients presented with mutism. The next most frequent signs were immobility/stupor (77.3%), withdrawal (35.3%), mannerisms (23.5%), and excitement/agitation (18.5%). Most cases presented with stuporous catatonia (75.6%). Catatonia most frequently occurred following resection of medulloblastoma (64.7%). Preoperative hydrocephalus occurred in 89 patients (74.8%). CONCLUSION: Catatonia was frequent in this PPCMS sample, with a predominant stuporous variant; it should be considered in patients with PPCMS and assessed with reliable and validated instruments for prompt diagnosis and management.

Infection control and the prevalence, management and outcomes of SARS-CoV-2 infections in mental health wards in London, UK: lessons learned from wave 1 to wave 2.

BACKGROUND: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) disease (COVID-19) has high morbidity and mortality in older adults and people with dementia. Infection control and prevention measures potentially reduce transmission within hospitals. AIMS: We aimed to replicate our earlier study of London mental health in-patients to examine changes in clinical guidance and practice and associated COVID-19 prevalence and outcomes between COVID-19 waves 1 and 2 (1 March to 30 April 2020 and 14 December 2020 to 15 February 2021). METHOD: We collected the 2 month period prevalence of wave 2 of COVID-19 in older (≥65 years) in-patients and those with dementia, as well as patients' characteristics, management and outcomes, including vaccinations. We compared these results with those of our wave 1 study. RESULTS: Sites reported that routine testing and personal protective equipment were available, and routine patient isolation on admission occurred throughout wave 2. COVID-19 infection occurred in 91/358 (25%; 95% CI 21-30%) v. 131/344, (38%; 95% CI 33-43%) P < 0.001 in wave 1. Hospitals identified more asymptomatic carriers (26/91; 29% v. 16/130; 12%) and fewer deaths (12/91; 13% v. 19/131; 15%; odds ratio = 0.92; 0.37-1.81) compared with wave 1. The patient vaccination uptake rate was 49/58 (85%). CONCLUSIONS: Patients in psychiatric in-patient settings, mostly admitted without known SARS-CoV-2 infection, had a high risk of infection compared with people in the community but lower than that during wave 1. Availability of infection control measures in line with a policy of parity of esteem between mental and physical health appears to have lowered within-hospital COVID-19 infections and deaths. Cautious management of vulnerable patient groups including mental health patients may reduce the future impact of COVID-19.

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 in pediatric obsessive-compulsive disorder: report of two cases.

Catatonia is a psychomotor syndrome which may occur in a wide variety of medical, neurological, and psychiatric conditions. In pediatrics, this condition is rare and is associated with high morbidity and mortality if not correctly diagnosed and treated. Catatonia in obsessive-compulsive disorder is an infrequent association that has been understudied and underdiagnosed. To add to the knowledge on this unusual clinical presentation, two pediatric patients are reported and discussed together with the other two cases described in the literature. These four cases in total of catatonia associated with OCD confirm that it is a relationship that is infrequently reported, possibly because of lack of awareness in clinicians that catatonia can also be caused by OCD, and because the similarity between some catatonic signs and some compulsive phenomena may compound the identification of the former. Most cases of catatonia in this small series seemed to have responded to the optimization of the treatment for OCD. This highlights the clinical importance of an accurate diagnosis of catatonia when associated with OCD.

Anti-NMDA receptor encephalitis in older adults: A systematic review of case reports.

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.

Recognition and Management of Antipsychotic-Induced Parkinsonism in Older Adults: A Narrative Review.

BACKGROUND: Parkinsonism is a common side-effect of antipsychotic drugs especially in older adults, who also present with a higher frequency of neurodegenerative disorders like Idiopathic Parkinson's disease (IPD). Distinguishing between antipsychotic-induced parkinsonism (AIP) and IPD is challenging due to clinical similarities. Up to 20% of older adults may suffer from persisting parkinsonism months after discontinuation of antipsychotics, suggesting underlying neurodegeneration. A review of the literature on AIP in older adults is presented, focusing on epidemiology, clinical aspects, and management. METHODS: A literature search was undertaken on EMBASE, MEDLINE and PsycINFO, for articles on parkinsonism induced by antipsychotic drugs or other dopamine 2 receptor antagonists in subjects aged 65 or older. RESULTS: AIP in older adults is the second most common cause of parkinsonism after IPD. Older age, female gender, exposure to high-potency first generation antipsychotics, and antipsychotic dosage are the main risk factors. The clinical presentation of AIP resembles that of IPD, but is more symmetrical, affects upper limbs more, and tends to have associated motor phenomena such as orofacial dyskinesias and akathisia. Presence of olfactory dysfunction in AIP suggests neurodegeneration. Imaging of striatal dopamine transporters is widely used in IPD diagnosis and could help to distinguish it from AIP. There is little evidence base for recommending pharmacological interventions for AIP, the best options being dose-reduction/withdrawal, or switching to a second-generation drug. CONCLUSIONS: AIP is a common occurrence in older adults and it is possible to differentiate it from IPD. Further research is needed into its pathophysiology and on its treatment.

Could COVID-19 anosmia and olfactory dysfunction trigger an increased risk of future dementia in patients with ApoE4?

The association of the coronavirus disease 2019 (COVID-19) with significant neurological and neuropsychiatric complications has been increasingly reported, both during the acute illness and in its aftermath. However, due to the short duration of patient follow up until now, it is not clear whether this infection will be associated with longer-term neurological and/or neuropsychiatric sequelae. In particular, the question of whether COVID-19 will be associated with an increased risk and rate of future dementia remains open and subject to speculation. During the course of the COVID-19 pandemic, an increasing number of patients have reported sudden anosmia or other olfactory dysfunction as concurrent symptoms. The possibility that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) may reach the brain via the olfactory nerve or an upper nasal trancribrial route is an interesting working hypothesis. Among the identified genetic risk factors for Late-onset Alzheimer's disease (LOAD), Apo E4 is one of the strongest and most frequent. People carrying one or two copies of the e4 allele of Apo E4 have significant odor recognition deficits in comparison to those not carrying this haplotype. The hypothesis invoked in this paper is that anosmia/olfactory dysfunctions induced by SARS-CoV-2 may cause an increased a risk of future neurodegenerative dementia in ApoE4 carriers, and that this risk would be higher than in Apo E4 carriers affected by anosmia not induced by SARS-CoV-2. This would be associated with virus-induced chronic modifications in the central nervous system. It is proposed that COVID-19 patients with anosmia and no other serious symptoms should be followed up as part of specifically designed and approved studies in order to identify the early stages of dementia (especially LOAD and Dementia with Lewy Bodies), thereby improving our knowledge of the mechanisms involved in pre-cognitive stages of neurodegenerative dementia and making best use of any available therapies. This latter opportunity is unique and should not be lost.

Catatonia in elderly psychiatric inpatients is not always associated with intense anxiety: Factor analysis and correlation with psychopathology.

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.

Catatonia in N-methyl-d-aspartate receptor antibody encephalitis: Phenomenological characteristics from a systematic review of case reports.

OBJECTIVE: To ascertain the phenomenological characterisation of catatonia in N-methyl-d-aspartate receptor antibody encephalitis (NMDAr-AbE). METHODS: A systematic review of case reports was undertaken in accordance with PRISMA guidelines. Case reports of NMDAr-AbE containing sufficient information on the cases' clinical presentation and meeting the study's inclusion criteria were selected. Cases were searched for clinical data in keeping with core catatonic signs by applying the screening instrument of the Bush-Francis Catatonia Rating Scale. When two or more core signs were ascertained catatonia was considered to be present. RESULTS: 2645 records were identified through the database search. Following screening and application of eligibility/inclusion criteria 139 articles were selected reporting on 189 individual subjects. Catatonia was present in 60% of these cases. The most prevalent signs were immobility/stupor (70%), mutism (67%), excitement (50%), posturing/catalepsy (34%), stereotypies (31%), and rigidity (30%). Immobility/stupor and excitement co-occurred in the same patient in 33% of cases. CONCLUSION: The phenomenological profile of catatonia in this sample of cases of NMDAr-AbE was characterised by a preponderance of signs in the hypokinetic spectrum. However, excitement often co-occurred in these patients suggesting that fluctuations in catatonic semiology may be frequent.

Depression and depressive symptoms in patients with polymyalgia rheumatica: discussion points, grey areas and unmet needs emerging from a systematic review of published literature.

OBJECTIVES: In 1979, Bird et al. proposed depression as a diagnostic criterion for polymyalgia rheumatica (PMR). More recently, the significance of depression in PMR patients has been re-proposed, , and some researchers have suggested that PMR may increase the risk of depression. The aim of our article is to evaluate the relationship between PMR and depression. MATERIAL AND METHODS: Systematic literature searches were performed on 19th and 20th May 2020 based on Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. The search was restricted to all studies and case reports with English abstract, published in any language, since 1979 (when depression was first proposed as a diagnostic criterion for PMR) describing the association of PMR with depression. Exclusion criteria were as follows: reviews, conference abstracts, comments, non-original articles; and articles discussing giant cell arteritis (GCA) and PMR when data and observations for the two conditions were not clearly subdivided. RESULTS: The initial search yielded 812 papers, of which 115 duplicates were removed. A total of 697 articles had a first screening and 506 were excluded based on title and abstract reviews; 117 articles underwent full-length scrutiny, and 99 full-text articles were excluded because they did not meet the inclusion and exclusion criteria (reviews and comments = 58; articles with outcome of interest not reported = 34; low-quality articles = 7). At least, 18 articles were included in this review. CONCLUSIONS: The review did not find any studies that clarified the prevalence rates of depression in patients with PMR. Furthermore, the studies reviewed did not offer any clarity as to whether patients suffered from just depressive symptoms or clinical depression, and that accepted diagnostic criteria for depression had not been employed, indicating that a robust method for diagnosing depression had not been employed. Collaboration of different professionals should be improved through shared guidelines.

Cognitive Function in Primary Sjögren's Syndrome: A Systematic Review.

BACKGROUND: Cognitive disorders are reported to be common in patients with primary Sjogren's syndrome (pSS). In some cases, they are the first clinical manifestation, preceding the diagnosis of pSS by two years on average. AIM: A systematic review was conducted to explore cognitive impairment in pSS, with reference to diagnostic methods and their relationship with laboratory data and clinical manifestations. MATERIALS AND METHODS: According to the PRISMA 2009 checklist, we carried out a comprehensive literature search in the three main bibliographic databases: MEDLINE, EMBASE, and PsycINFO (NICE HDAS interface). The following main search terms were used: primary Sjogren syndrome, neurological manifestations, fatigue, cognitive functions, psychiatric manifestations, mild cognitive impairment, dementia, and neurocognitive disorder. The search was made on 14 September, 2018. References from all selected studies were also examined. Inclusion criteria were: all studies and case-reports published in any language from 2002 that assessed the association of pSS (according to classification criteria proposed by the 2002 American/European collaborative group (AECG)) with all types of cognitive impairment (including dementia). Exclusion criteria were: reviews, abstracts, secondary Sjögren's syndrome (SS), and all articles in which other classification criteria were used. RESULTS: The initial search yielded 352 articles, of which 253 were excluded based on the title and abstract review. A total of 54 articles underwent a full-length review, and 32 articles were excluded. Data were extracted from 18 studies and three case-reports involving a total of 6196 participants. In most cases, cognitive dysfunction was a brain fog or a mild cognitive impairment (MCI). Occasionally, an autoimmune dementia was present. The relationship between pSS and degenerative dementias, such as Alzheimer's disease (AD), was a controversial issue, even if some investigators hypothesized that pSS could be a risk factor. Several unmet needs were highlighted. First, some of the included studies had not reported the severity of pSS; hence, few correlations between disease severity and cognitive function were possible. Secondly, the evaluation of the pathogenetic role of comorbid diseases was often absent. The lack of information on the type of dementia represented a third critical point in the majority of the included studies. CONCLUSIONS: This systematic review confirmed that adequate studies on cognitive function in pSS are scarce, mostly performed on small-sized samples, and often conflicting. The routine assessment of cognitive function in patients with pSS seems advisable and it will help to elucidate some of the unmet needs highlighted by this review in future appropriately designed studies.

Behavioral, Psychiatric, and Cognitive Adverse Events in Older Persons Treated with Glucocorticoids.

Background: Since the introduction of glucocorticoids (GCs) in the physician's pharmacological arsenal, it has been known that they are a cause of behavioral or psychiatric adverse events (BPAE), as well as of cognitive problems. To the best of our knowledge, the relationship between these adverse events and GCs in older persons has never been evaluated, except through case-reports or series with few cases. In this paper, a review of the literature regarding BPAEs and cognitive disorders in older people treated with CSs is undertaken. Methods: A comprehensive literature search for BPAEs was carried out on the three main bibliographic databases: EMBASE, MEDLINE and PsycINFO (NICE HDAS interface). Emtree terms were: Steroid, steroid therapy, mental disease, mania, delirium, agitation, depression, behavior change, dementia, major cognitive impairment, elderly. The search was restricted to all clinical studies and case reports with focus on the aged (65+ years) published in any language since 1998. Results: Data on the prevalence of the various BPAEs in older patients treated with GCs were very scarse, consisting mainly of case reports and of series with small numbers of patients. It was hence not possible to perform any statistical evaluation of the data (including meta-analysis). Amongst BPAEs, he possibility that delirium can be induced by GCs has been recently been questioned. Co-morbidities and polypharmacy were additional risk factors for BPAEs in older persons. Conclusions: Data on BPAEs in older persons treated with GCs, have several unmet needs that need to be further evaluated with appropriately designed studies.

Recognizing Catatonia in Medically Hospitalized Older Adults: Why It Matters.

Catatonia is a neuropsychiatric syndrome characterized by a variety of motor, behavioral, emotional, and autonomic abnormalities caused by general medical, neurological, and psychiatric disorders, as well as by medications and drugs of abuse. Although there has been a plethora of research on catatonia over the last twenty years, it is still underdiagnosed. Studies of catatonia involving older adults have been sparse, despite its apparent high prevalence, higher risk of serious complications, and of association with non-psychiatric causes. This paper aims to provide an introduction to catatonia as a syndrome, as well as an account of its specificities in older adults, especially those in general hospitals, with the aim to raise awareness of catatonia amongst clinicians working with this age group in acute medical settings, so improvements in its diagnostic rates, treatment, and outcomes can be achieved.

Catatonia in Patients with Dementia Admitted to a Geriatric Psychiatry Ward.

To determine the frequency and characteristics of catatonia in persons with dementia, all patients admitted to an old age psychiatry ward were screened for catatonia with the Bush-Francis Catatonia Screening Instrument (BFCSI) over a period of 6 months. Thirty-seven patients were admitted, and there were 14 patients with dementia. The rate of catatonia in these patients was 42.8% (6 out of 14). Five out of six of these patients received treatment for catatonia with lorazepam, all achieving complete remission. Catatonia occurred frequently in patients admitted with dementia.

Afasia progresiva primaria: aspectos clínicos y diagnósticos / No disponible

La Degeneración Lobar Frontotemporal (DLFT) es una entidad neurodegenerativa heterogénea que abarca varios síndromes clínicos diferenciados según su fenotipo, el cual viene determinado por la distribución neuropatológica inicial (frontal o bien temporal), y en los que una alteración progresiva del lenguaje es un hallazgo fundamental. Esto es así especialmente en la variante temporal de la DLFT que también se conoce como Afasia Progresiva Primaria (APP), y que tiende a presentar neuropatología de complejo Pick/Demencia Frontotemporal, o bien de enfermedad de Alzheimer. La APP se caracteriza por debutar con una alteración progresiva del lenguaje que causa un trastorno de la funcionalidad, y con una conservación inicial de otras funciones cognitivas. Aunque los pacientes con APP suelen ser derivados a neurólogos, es importante que los psicogeriatras, y especialmente aquéllos que trabajan con pacientes con demencia, estén familiarizados con este síndrome y que sepan valorar de forma adecuada el lenguaje como función cognitiva. Los pacientes con APP suelen también presentar trastornos de naturaleza neuroconductual y psiquiátrica, y por esta razón, el rol del psicogeriatra será fundamental en su valoración y su tratamiento

Complaints about poor memory and cognitive function found not to be due to dementia are common in the general population, and they are a reason for consultation in primary care and of referrals to specialist services. This could increase the risk of overdiagnosing dementia in a proportion of patients. Various clinical entities that present with mild to moderate memory dysfunction and their possible pathophysiological mechanisms are reviewed in this paper, with the aim to assist the clinician in the differential diagnosis, the consideration of their risk of conversion to dementia, and in deciding on their best possible 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.
