An exploratory study of the damage markers NfL, GFAP, and t-Tau, in cerebrospinal fluid and other findings from a patient cohort enriched for suspected autoimmune psychiatric disease. Transl Psychiatry 2024; 14:304. [PMID: 39048548 PMCID: PMC11269634 DOI: 10.1038/s41398-024-03021-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/25/2023] [Revised: 06/27/2024] [Accepted: 07/10/2024] [Indexed: 07/27/2024] Open
Abstract
There is growing evidence suggesting that immunological mechanisms play a significant role in the development of psychiatric symptoms in certain patient subgroups. However, the relationship between clinical red flags for suspected autoimmune psychiatric disease and signs of central nervous system (CNS) pathology (e.g., routine cerebrospinal fluid (CSF) alterations, CNS damage markers, neurophysiological or neuroimaging findings) has received limited attention. Here, we aimed to describe the prevalence and distribution of potential CNS pathologies in psychiatric patients in relation to clinical red flags for autoimmune psychiatric disease and psychiatric symptoms. CSF routine findings and CNS damage markers; neurofilament light chain protein (NfL), glial fibrillary acidic protein (GFAP) and total Tau (t-Tau), in CSF from 127 patients with psychiatric disease preselected for suspected immunological involvement were related to recently proposed clinical red flags, psychiatric features, and MRI and EEG findings. Twenty-one percent had abnormal routine CSF findings and 27% had elevated levels of CNS damage markers. Six percent had anti-neuronal antibodies in serum and 2% had these antibodies in the CSF. Sixty-six percent of patients examined with MRI (n = 88) had alterations, mostly atrophy or nonspecific white matter lesions. Twenty-seven percent of patients with EEG recordings (n = 70) had abnormal findings. Elevated NfL levels were associated with comorbid autoimmunity and affective dysregulation symptoms. Elevated t-Tau was associated with catatonia and higher ratings of agitation/hyperactivity. Elevated GFAP was associated with acute onset, atypical presentation, infectious prodrome, tics, depressive/anxiety symptom ratings and overall greater psychiatric symptom burden. In conclusion, preselection based on suspected autoimmune psychiatric disease identifies a population with a high prevalence of CSF alterations suggesting CNS pathology. Future studies should examine the value of these markers in predicting treatment responses.

Electromyographic Characteristics of Postactivation Effect in Dopamine-Dependent Spectrum Models Observed in Parkinson's Disease and Schizophrenia. Biomedicines 2024; 12:1338. [PMID: 38927545 PMCID: PMC11202052 DOI: 10.3390/biomedicines12061338] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2024] [Revised: 06/14/2024] [Accepted: 06/16/2024] [Indexed: 06/28/2024] Open
Abstract
This study aimed to test the hypothesis that the postactivation effect (PAE, involuntary normal muscle tone) is modified by dopaminergic mechanisms. The PAE was tested with surface electromyography (sEMG) in the "off medication" phase in participants with Parkinson's disease (PDoff) and in the "on medication" state in participants with schizophrenia (SZon), which modeled hypodopaminegic conditions, and in participants with PD "on medication" (PDon) and in participants with SZ "off medication" (SZoff) state which modeled the hyperdopaminergic conditions. Healthy age-matched participants constituted the control group (HC, n = 11). In hyperdopaminergic models, PAE was triggered in 71.3% of participants in SZoff and in 35.7% in PDon conditions. In the hypodopaminergic models, PAE was triggered in 12% in SZon and in 21.4% in PDoff conditions. In the HC group, PAE was present in 91% of participants. In the HC and PD groups, the mean frequency and correlation dimension of sEMG at PAE was higher than that during voluntary isometric contraction. In conclusion, in hypodopaminergic models, PAE triggering was inhibited. The manifestations and EMG characteristics of PAE in people with PD or SZ may indicate dopaminergic dysfunction.

Abstract
BACKGROUND Catatonia is a neuropsychiatric disorder characterised by psychomotor changes that can affect individuals across the lifespan. Although features of catatonia have been described in adults, the most common clinical symptoms among paediatric patients with catatonia are not well characterised. AIMS The goal of this study was to characterise the symptoms of catatonia demonstrated by paediatric patients, and to explore demographic and diagnostic factors associated with greater catatonia severity. METHOD We conducted a multicentre retrospective cohort study, from 1 January 2018 to 6 January 2023, of patients aged 18 and younger with a clinical diagnosis of catatonia and symptom assessment using the Bush Francis Catatonia Rating Scale (BFCRS). RESULTS A total of 143 patients met inclusion criteria. The median age was 15 (interquartile range: 13-16) years and 66 (46.2%) patients were female. Neurodevelopmental disabilities were present in 55 (38.5%) patients. Patients demonstrated a mean of 6.0 ± 2.1 signs of catatonia on the Bush Francis Catatonia Screening Item, with a mean BFCRS score of 15.0 ± 5.9. Among the 23 items of the BFCRS, six were present in >50% of patients (staring, mutism, immobility/stupor, withdrawal, posturing/catalepsy, rigidity), and four were present in <20% of cases (waxy flexibility, mitgehen, gegenhalten, grasp reflex). In an adjusted model, patients with neurodevelopmental disorders demonstrated greater BFCRS severity than those with other diagnoses. CONCLUSIONS Catatonia was diagnosed in a range of mental health conditions. Further research is needed to define optimal diagnostic criteria for catatonia in paediatric patients, and clarify the clinical course of the disorder.

Abstract
BACKGROUND In Kalhbaum's first characterization of catatonia, the emotional symptoms, such as decreased or restricted expression of feelings and emotions, which is described as blunted affect, are related to the motor symptoms. In later years, the affective domain was excluded from the concept of catatonia and was not included among the diagnostic criteria in the various Diagnostic Statistical Manual (DSM) versions. In recent times, some authors have proposed the proposition of reevaluating the notion of catatonia through the reintroduction of the affective domain. The objective of this study was to examine the correlation between catatonic-like behavior (CLB), such as emotional withdrawal, blunted affect, and psychomotor slowing, and inflammatory markers, namely the neutrophil/lymphocytes ratio (NLR) and lymphocytes/monocytes ratio (LMR), in individuals diagnosed with schizophrenia. METHOD A sample of 25 patients with schizophrenia (10 females, 15 males) was recruited, and the Brief Psychiatric Rating Scale (BPRS) was used to assess the severity of emotional withdrawal, blunted affect, and psychomotor slowing. FINDINGS The correlation analysis (Spearman ρ) revealed a robust direct association between blunted affect and psychomotor slowing (ρ = 0.79, P = 0.001), and a significant direct correlation between CLB (emotional withdrawal, ρ = 0.51, P = 0.05; blunted affect ρ = 0.58, P = 0.05; motor retardation, ρ = 0.56, P = 0.05) and LMR (ρ = 0.53, P = 0.05). In addition, patients with a duration of illness (DOI) older than five years had a higher presence of CLB and a higher LMR than patients with a more recent diagnosis of the disease. Likely, patients with positive symptoms and in the prodromal and active stages of the disease have a different immune profile than patients in the residual stage and with a predominance of negative symptoms. CONCLUSIONS Psychomotor slowing and blunted affect are two significantly related features, representing the two-faced Janus of immobility. Furthermore, aggregating them in CLB is more predominant the longer the duration of schizophrenia and is associated with different a specific pattern of immune activation.

Psychomotor slowing alters gait velocity, cadence, and stride length and indicates negative symptom severity in psychosis. SCHIZOPHRENIA (HEIDELBERG, GERMANY) 2022; 8:116.

Abstract
Schizophrenia is a severe mental disorder, in which 50% of the patients present with motor abnormalities such as psychomotor slowing. Slow spontaneous gait has been reported in schizophrenia. However, comprehensive objective instrumental assessments of multiple gait conditions are missing. Finally, the specific gait patterns of subjects with psychomotor slowing are still unknown. Therefore, this study aimed to objectively assess multiple gait parameters at different walking conditions in patients with schizophrenia with and without psychomotor slowing. Also, we hypothesised gait impairments to correlate with expert ratings of hypokinetic movement disorders and negative symptoms. We collected gait data (GAITRite®) in 70 patients with psychomotor slowing (SRRS (Salpetriere retardation rating scale) ≥15), 22 non-psychomotor slowed patients (SRRS < 15), and 42 healthy controls. Participants performed four walking conditions (self-selected speed, maximum speed, head reclined, and eyes closed) and six gait parameters were extracted (velocity, cadence, stride length, functional ambulation profile (FAP), and variance of stride length and time). Patients with psychomotor slowing presented slower velocity, lower cadence, and shorter stride length in all walking conditions compared to healthy controls, with the non-slowed patients in an intermediate position (all F > 16.18, all p < 0.001). Secondly, slower velocity was associated with more severe hypokinetic movement disorders and negative symptoms. In conclusion, gait impairments exist in a spectrum with healthy controls on one end and patients with psychomotor slowing on the other end. Patients with psychomotor slowing are specifically impaired when an adaptation of gait patterns is required, contributing to the deleterious effects of sedentary behaviours.

Abstract
The rapidly evolving field of sensorimotor neuroscience reflects the scientific and clinical relevance of sensorimotor abnormalities as an intrinsic component of the disease process, e.g., in patients with schizophrenia spectrum disorders (SSD). Despite previous efforts, however, prevalence rates and relationships between different categories of sensorimotor abnormalities in SSD patients are still subject of ongoing debate. In this study, we examined five different categories of the sensorimotor domain (Neurological soft signs (NSS), parkinsonism, catatonia, akathisia, and tardive dyskinesia) according to well-established clinical ratings scales and the respective cut-off criteria in a sample of 131 SSD patients. We used a collection of statistical methods to better understand prevalence, overlap and heterogeneity, as well as psychopathological and cognitive correlates of sensorimotor abnormalities. 97.7% of the SSD patients considered by this study exhibited at least one categorically defined sensorimotor abnormality that tended to co-vary within three different sensorimotor subgroups (moderate, hyperkinetic and hypokinetic). Finally, hyperkinetic and hypokinetic groups differed significantly in their neurocognitive performance compared with the moderate group. The results suggest different patterns of clinical overlap, highlight the relationship between sensorimotor and cognitive domain and provide clues for further neurobiological studies.

Abstract
BACKGROUND The external clinical manifestations (psychopathology) and internal subjective experience (phenomenology) of catatonia are of clinical importance but have received little attention. This study aimed to use a large dataset to describe the clinical signs of catatonia; to assess whether these signs are associated with underlying diagnosis and prognosis; and to describe the phenomenology of catatonia, particularly with reference to fear. METHODS A retrospective descriptive cross-sectional study was conducted using the electronic healthcare records of a large secondary mental health trust in London, United Kingdom. Patients with catatonia were identified in a previous study by screening records using natural language processing followed by manual validation. The presence of items of the Bush-Francis Catatonia Screening Instrument was coded by the investigators. The presence of psychomotor alternation was assessed by examining the frequency of stupor and excitement in the same episode. A cluster analysis and principal component analysis were conducted on catatonic signs. Principal components were tested for their associations with demographic and clinical variables. Where text was available on the phenomenology of catatonia, this was coded by two authors in an iterative process to develop a classification of the subjective experience of catatonia. RESULTS Searching healthcare records provided 1,456 validated diagnoses of catatonia across a wide range of demographic groups, diagnoses and treatment settings. The median number of catatonic signs was 3 (IQR 2-5) and the most commonly reported signs were mutism, immobility/stupor and withdrawal. Stupor was present in 925 patients, of whom 105 (11.4%) also exhibited excitement. Out of 196 patients with excitement, 105 (53.6%) also had immobility/stupor. Cluster analysis produced two clusters consisting of negative and positive clinical features. From principal component analysis, three components were derived, which may be termed parakinetic, hypokinetic and withdrawal. The parakinetic component was associated with women, neurodevelopmental disorders and longer admission duration; the hypokinetic component was associated with catatonia relapse; the withdrawal component was associated with men and mood disorders. 68 patients had phenomenological data, including 49 contemporaneous and 24 retrospective accounts. 35% of these expressed fear, but a majority (72%) gave a meaningful narrative explanation for the catatonia, which consisted of hallucinations, delusions of several different types and apparently non-psychotic rationales. CONCLUSION The clinical signs of catatonia can be considered as parakinetic, hypokinetic and withdrawal components. These components are associated with diagnostic and prognostic variables. Fear appears in a large minority of patients with catatonia, but narrative explanations are varied and possibly more common.

Abstract
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.

Abstract
Catatonia is a psychomotor syndrome defined by a constellation of predominantly motor symptoms. The aim of the present study was to determine whether recently admitted psychiatric patients with catatonia exhibited higher serum C-reactive protein (hs-CRP) levels compared to non-catatonic psychiatric patients and healthy controls (HCs). Recently admitted psychiatric patients were screened and evaluated for the catatonia syndrome using the Bush-Francis Catatonia Rating Scale and the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5). The study sample was formed by 150 individuals (39 male and 111 female), including 51 catatonic patients, 55 non-catatonic patients, and 44 HCs. Serum hs-CRP levels were processed with the enzyme-linked immunosorbent assay. Serum levels of creatine kinase (CK), adrenocorticotropic hormone (ACTH), immunoglobulin G (IgG), complement component 3 (C3), and complement component 4 (C4) were also determined. There was a significantly higher percentage of patients with high inflammatory levels (hs-CRP > 3000ng/ml) in the catatonic (43.1%) than in the non-catatonic (14.5%) or HCs group (9.1%) (χ 2 =18.9, P < .001). Logistic regression showed that catatonic patients had significantly higher hs-CRP levels compared to non-catatonic patients even after controlling for other clinical and laboratory variables (OR = 3.52, P = .015, 95% CI 1.28-9.79). Multiple linear regression analysis revealed that log-transformed hs-CRP was independently predicted by body mass index and log-transformed C4, ACTH, and Cortisol in catatonic patients. Findings of the present study suggest that catatonia is specifically linked to a higher level of systemic inflammation, not merely attributable to the overall psychopathology, or alterations in the stress level and complement system.

Aandi Subramaniyam B, Muliyala KP, Suchandra HH, Reddi VSK. Diagnosing catatonia and its dimensions: Cluster analysis and factor solution using the Bush Francis Catatonia Rating Scale (BFCRS). Asian J Psychiatr 2020; 52:102002. [PMID: 32506001 DOI: 10.1016/j.ajp.2020.102002] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/18/2019] [Revised: 02/29/2020] [Accepted: 03/16/2020] [Indexed: 02/07/2023]
Abstract
Advances in research into catatonia in the preceding two decades has offered increasing clarity and an improved understanding of various aspects of this complex syndrome. Despite the above, there are several aspects that hinder a broader interpretation of these findings, the most common being a lack of consensus on the criteria required for diagnosing catatonia. Whilst being the most frequently used tool for diagnosis, the number of signs from Bush-Francis Catatonia Rating Scale (BFCRS) needed to diagnose catatonia remain unclear. This study aimed to determine the number of signs required to accurately diagnose catatonia using BFCRS and delineate its dimensions in an acute inpatient unit in the Indian setting. A random sample of 300 patients were evaluated for catatonia within 24 h of admission. Cluster Analysis followed by discriminant analysis and receiver operating curve analysis (ROC) provided cut-off values for diagnosing catatonia syndrome. Principle Component Analysis (PCA) with varimax rotation was used to identify factors in those with catatonia. Findings revealed that a cut off of two signs from both Bush-Francis Catatonia Screening Instrument or BFCSI (sensitivity of 100 %, specificity of 96.2 % as well as a positive predictive value [PPV] of 79.6 % and negative predictive value [NPV] 100 % with ROC AUC value of 0.98) and complete BFCRS (sensitivity of 100 % and specificity of 90.7 %, PPV of 80.7 and NPV of 100 % with ROC AUC for at least two items cut-off being 0.95) accurately detected catatonia. However, the prevalence of catatonia in the same population increased by 4% from 16.3% to 20.3% using the BFCRS rather than the BFCSI. The BFCRS generated a 3-factor model accounting for 65.48 % variance offering the best fit, indicating three discrete dimensions to catatonia, namely retarded, excited and what we named as "aberrant volitional". Interestingly, the aberrant volitional dimension comprises of signs that need to be elicited rather than passively observed and excluding one, none of them are part of the BFCSI. Findings of this study suggest that the BFCRS more accurately detects catatonia rather than the BFCSI. Additionally, three dimensions of catatonia more coherently explain the catatonic syndrome given that 55.7 % of the sample had signs from more than one factor concurrently. We propose that the BFCRS rather than BFCSI be routinely administered for evaluating all suspected cases of catatonia to ensure more accurate detection as well as identifying the aberrant volitional dimensional signs more consistently. The three-dimensional model also offers great opportunities to further unravel the pathophysiological basis of catatonic signs more systematically.

Abstract
Catatonia is a psychomotor syndrome associated with several psychiatric and medical conditions. Psychomotor signs range from stupor to agitation, and include pathognomonic features such as verbigeration and waxy flexibility. Disturbances of volition led to the classification of catatonia as a subtype of schizophrenia, but changes in nosology now recognise the high prevalence in mood disorders, overlap with delirium, and comorbidity with medical conditions. Initial psychometric studies have revealed three behavioural factors, but the structure of catatonia is still unknown. Evidence from brain imaging studies of patients with psychotic disorders indicates increased neural activity in premotor areas in patients with hypokinetic catatonia. However, whether this localised hyperactivity is due to corticocortical inhibition or excess activity of inhibitory corticobasal ganglia loops is unclear. Current treatment of catatonia relies on benzodiazepines and electroconvulsive therapy-both effective, yet unspecific in their modes of action. Longitudinal research and treatment studies, with neuroimaging and brain stimulation techniques, are needed to advance our understanding of catatonia.

Abstract
Abnormal fine motor function is a frequent finding in schizophrenia and has been linked to structural and functional brain alterations. However, whether fine motor function is related to functional alterations within the motor system remains unclear. The aim of this study was to assess whether abnormalities in resting-state functional connectivity are present in schizophrenia patients and to investigate how these abnormalities may be related to fine motor function. We examined 19 schizophrenia patients and 16 healthy controls using resting-state functional connectivity for 11 bilateral regions of interest. Fine motor function was assessed on a set of copying tasks and the Symbol-Digit-Substitution Test. We found significantly reduced functional connectivity between the left caudate nucleus and bilateral dorsolateral prefrontal cortex (DLPFC) and between the left putamen and bilateral supplementary motor area (SMA) proper in patients compared to controls. Altered connectivity from DLPFC to caudate nucleus was related to fine motor tasks, which are sensitive to psychomotor speed, whereas aberrant connectivity between the SMA proper and putamen was associated to both, fine motor task, which are sensitive to psychomotor speed and to speed of information processing. Our findings emphasize the role of fronto-striatal connections in the pathogenesis of fine motor impairments in schizophrenia.

Abstract
A widely accepted consensus holds that a variety of motor symptoms subsumed under the term 'catatonia' have been an integral part of the symptomatology of schizophrenia since 1896, when Kraepelin proposed the concept of dementia praecox (schizophrenia). Until recently, psychiatric classifications included catatonic schizophrenia mainly through tradition, without compelling evidence of its validity as a schizophrenia subtype. This selective review briefly summarizes the history, psychopathology, demographic and epidemiological data, and treatment options for schizophrenia with prominent catatonic features. Although most catatonic signs and symptoms are easy to observe and measure, the lack of conceptual clarity of catatonia and consensus about the threshold and criteria for its diagnosis have hampered our understanding of how catatonia contributes to the pathophysiology of schizophrenic psychoses. Diverse study samples and methodologies have further hindered research on schizophrenia with prominent catatonic features. A focus on the motor aspects of broadly defined schizophrenia using modern methods of detecting and quantifying catatonic signs and symptoms coupled with sophisticated neuroimaging techniques offers a new approach to research in this long-overlooked field.

Abstract
INTRODUCTION Aberrant motor function is an integral part of schizophrenia. In fact, abnormalities are frequently found in patients, in populations at risk, and in unaffected relatives. Motor abnormalities are suspected to be relevant for the clinical outcome and could probably predict the conversion from at-risk individuals to schizophrenia. Furthermore, motor function has been argued as endophenotype of the disorder. Yet, which particular motor domain may classify as a potential endophenotype is unknown. We aimed to compare schizophrenia patients, unaffected first-degree relatives and healthy controls for different motor domains. We expected impairments in all domains in patients and in some domains in relatives. METHOD We included 43 schizophrenia patients, 34 unaffected first-degree relatives of schizophrenia patients, and 29 healthy control subjects, matched for age, gender, and education level. We compared motor function of four motor domains between the groups. The domains comprise neurological soft signs (NSS), abnormal involuntary movements (dyskinesia), Parkinsonism, and fine motor function including simple [finger tapping (FT)] and complex fine motor function, (i.e., dexterity as measured with the coin rotation test). Furthermore, we tested the association of motor function of the four domains with working memory, frontal lobe function, and nonverbal intelligence for each group separately using within-group bivariate correlations. RESULTS Schizophrenia patients showed poorer motor function in all tested domains compared to healthy controls. First-degree relatives had intermediate ratings with aberrant function in two motor domains. In detail, relatives had significantly more NSS and performed poorer in the FT task than controls. In contrast, complex fine motor function was intact in relatives. Relatives did not differ from controls in dyskinesia or Parkinsonism severity. DISCUSSION Taken together, schizophrenia patients have motor abnormalities in all tested domains. Thus, motor abnormalities are a key element of the disorder. Likewise, first-degree relatives presented motor deficits in two domains. A clear difference between relatives and healthy controls was found for NSS and FT. Thus, NSS and FT may be potential markers of vulnerability for schizophrenia. The lack of association between genetic risk and dyskinesia or Parkinsonism suggests distinct pathobiological mechanisms in the various motor abnormalities in schizophrenia.

Abstract
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). Patients did not differ in antipsychotic medication or positive symptoms. We acquired whole-brain rCBF using arterial spin labeling and GM density. We compared whole-brain perfusion and GM density over all and between the groups using 1-way ANCOVAs (F and T tests). We found a group effect (F test) of rCBF within bilateral supplementary motor area (SMA), anterior cingulate cortex, dorsolateral prefrontal cortex, left interior parietal lobe, and cerebellum. T tests indicated 1 cluster (SMA) to be specific to catatonia. Moreover, catatonia of excited and retarded types differed in SMA perfusion. Furthermore, increased catatonia severity was associated with higher perfusion in SMA. Finally, catatonia patients had a distinct pattern of GM density reduction compared to controls with prominent GM loss in frontal and insular cortices. SMA resting-state hyperperfusion is a marker of current catatonia in schizophrenia. This is highly compatible with a dysregulated motor system in catatonia, particularly affecting premotor areas. Moreover, SMA perfusion was differentially altered in retarded and excited catatonia subtypes, arguing for distinct pathobiology.

Abstract
Background Motor abnormalities (MAs) of severe mental disorders have been traditionally neglected both in clinical practice and research, although they are an increasing focus of attention because of their clinical and neurobiological relevance. For historical reasons, most of the literature on MAs has been focused to a great extent on schizophrenia, and as a consequence their prevalence and featural properties in other psychiatric or neuropsychiatric disorders are poorly known. In this article, we evaluated the extent to which catatonic, extrapyramidal and neurological soft signs, and their associated clinical features, are present transdiagnostically. Methods We examined motor-related features in neurodevelopmental (schizophrenia, obsessive compulsive disorder, autism spectrum disorders), "functional" (nonschizophrenic nonaffective psychoses, mood disorders) and neurodegenerative (Alzheimer's disease) disorders. Examination of the literature revealed that there have been very few comparisons of motor-related features across diagnoses and we had to rely mainly in disorder-specific studies to compare it transdiagnostically. Results One or more motor domains had a substantial prevalence in all the diagnoses examined. In "functional" disorders, MAs, and particularly catatonic signs, appear to be markers of episode severity; in chronic disorders, although with different degree of strength or evidence, all motor domains are indicators of both disorder severity and poor outcome; lastly, in Alzheimer's disease they are also indicators of disorder progression. Conclusions MAs appear to represent a true transdiagnostic domain putatively sharing neurobiological mechanisms of neurodevelopmental, functional or neurodegenerative origin.

Abstract
INTRODUCTION Despite the increased recognition of catatonia in children and adolescents, no specific assessment instrument has been validated in this population. METHOD Within the context of a prospective study on catatonia, we developed the Pediatric Catatonia Rating Scale (PCRS, maximum score=60), adapted from the Bush and Francis Catatonia Rating Scale for its use in child and adolescent inpatients. We assessed the psychometric properties of the PCRS by measuring its internal consistency, construct validity, and factor structure. Bivariate analyses were performed to compare the different diagnostic patient groups across the extracted factors. RESULTS Internal consistency was moderate (Cronbach's α for total score=0.67) suggesting multidimensionality. Multiple factors underlie the PCRS items, as revealed by factor analysis. Four distinct dimensions of catatonic symptoms were identified and accounted for 44% of total variance: a "negative withdrawal" factor (with mutism, negativism, and social withdrawal), a "catalepsy" factor (with posturing and waxy flexibility), an "abnormal movements" factor (with mannerisms and stereotypes) and an "echo phenomenon" factor (with echolalia and echopraxia). Receiver operating characteristic (ROC) analysis showed that the PCRS performance in discriminating individuals with catatonia vs. those without catatonia was excellent for a threshold≥9 (Area Under the Curve=0.983) in this sample. DISCUSSION These results support the validity of the PCRS among children and adolescent inpatients. With regard to such analyses, the internal structure of catatonic syndrome in children and adolescents is roughly comparable with the adult form, except the lack of a "hyperactive/excitement" dimension.

Abstract
One of the most exciting psychiatric conditions is the bizarre psychomotor syndrome called catatonia, which may present with a large number of different motor signs and even vegetative instability. Catatonia is potentially life threatening. The use of benzodiazepines and electroconvulsive therapy (ECT) has been efficient in the majority of patients. The rich clinical literature of the past has attempted to capture the nature of catatonia. But the lack of diagnostic clarity and operationalization has hampered research on catatonia for a long time. Within the last decades, it became clear that catatonia had to be separated from schizophrenia, which was finally accomplished in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5). In DSM-5, catatonia syndrome may be diagnosed as a specifier to major mood disorders, psychotic disorders, general medical conditions, and as catatonia not otherwise specified. This allows diagnosing the syndrome in a large variety of psychiatric disorders. Currently, the pathobiology remains widely unknown. Suspected neurotransmitter systems include gamma-aminobutyric acid (GABA) and glutamate. Neuroimaging reports pointed to reduced resting state activity and reduced task activation in motor areas of the frontal and parietal cortex. The new classification of catatonia will foster more clinical research and neuroscientific approaches by testing catatonia in various populations and applying stringent criteria. The scarce number of prospective trials will hopefully increase, as more trials will be encouraged within a more precise concept of catatonia.

Abstract
Catatonia is a psychomotor syndrome which has historically been associated with schizophrenia. Many clinicians have thought that the prevalence of this condition has been decreasing over the past few decades. This review reminds clinicians that catatonia is not exclusively associated with schizophrenia, and is still common in clinical practice. Many cases are related to affective disorders or are of an idiopathic nature. The illusion of reduced prevalence has been due to evolving diagnostic systems that failed to capture catatonic syndromes. This systemic error has remained unchallenged, and potentiated by the failure to perform adequate neurological evaluations and catatonia screening exams on psychiatric patients. We find that current data supports catatonic syndromes are still common, often severe and of modern clinical importance. Effective treatment is relatively easy and can greatly reduce organ failure associated with prolonged psychomotor symptoms. Prompt identification and treatment can produce a robust improvement in most cases. The ongoing prevalence of this syndrome requires that psychiatrists recognize catatonia and its presentations, the range of associated etiologies, and the import of timely treatment.

Abstract
Although the prevalence and severity of catatonia may have decreased over time, it is still a highly relevant, frequently occurring symptom cluster that can be observed in schizophrenia patients. Apart from this syndrome, neurological soft signs, psychomotor slowing and extrapyramidal symptoms are other psychomotor symptom clusters that are part of the clinical picture of schizophrenia. In this overview, the relevance of catatonia as a contemporary symptom cluster of the illness as well as its relationship with other psychomotor symptoms of the illness are discussed.

Abstract
This study aimed to evaluate the symptom threshold for making the diagnosis of catatonia. Further the objectives were to (1) to study the factor solution of Bush Francis Catatonia Rating Scale (BFCRS); (2) To compare the prevalence and symptom profile of catatonia in patients with psychotic and mood disorders among patients admitted to the psychiatry inpatient of a general hospital psychiatric unit. 201 patients were screened for presence of catatonia by using BFCRS. By using cluster analysis, discriminant analysis, ROC curve, sensitivity and specificity analysis, data suggested that a threshold of 3 symptoms was able to correctly categorize 89.4% of patients with catatonia and 100% of patients without catatonia. Prevalence of catatonia was 9.45%. There was no difference in the prevalence rate and symptom profile of catatonia between those with schizophrenia and mood disorders (i.e., unipolar depression and bipolar affective disorder). Factor analysis of the data yielded 2 factor solutions, i.e., retarded and excited catatonia. To conclude this study suggests that presence of 3 symptoms for making the diagnosis of catatonia can correctly distinguish patients with and without catatonia. This is compatible with the recommendations of DSM-5. Prevalence of catatonia is almost equal in patients with schizophrenia and mood disorders.

Abstract
BACKGROUND The classification of catatonia has fluctuated and underwent recent changes in DSM-5. The current study examines the prevalence of catatonia signs, estimates the utility of diagnostic features, identifies core catatonia signs, and explores their underlying structure. METHOD We screened 339 acutely ill medical and psychiatric patients with the Bush Francis Catatonia Rating Scale (BFCRS). We examined prevalence and severity of catatonia signs and compared BFCRS, DSM-IV and DSM-5 diagnoses. We used principal component analysis (PCA) to examine the factorial validity of catatonia and item response theory (IRT) to estimate each sign's utility and reliability. RESULTS Out of the 339 patients, 300 were diagnosed with catatonia using the BFCRS and 232 catatonia diagnoses were validated by the treating provider based on selection for treatment with benzodiazepines or electroconvulsive therapy. Of the 232 validated catatonia cases, 211 (91%) met DSM-IV criteria but only 170 (73%) met DSM-5 criteria for catatonia. Staring was the most prevalent catatonia sign. PCA identified three components, interpretable as "Increased, Abnormal and Decreased Psychomotor Activity," although 63% of the variance was unexplained. IRT showed that Excitement, Waxy Flexibility and Immobility/Stupor were the best indicators of each factor. The BFCRS had many redundant items and as a whole had low reliability at low severity of catatonia, but good reliability at moderate-high severity of catatonia. CONCLUSIONS The structure of catatonia remains to be discovered.

Abstract
OBJECTIVE Catatonia, extrapyramidal signs, psychomotor slowing, and (motoric) neurological soft signs are well-known psychomotor symptoms in schizophrenia. This study aims at investigating the interrelations between these symptoms. In addition, associations between psychomotor symptoms, clinical symptoms, and cognitive functioning will be studied. METHOD An extensive test battery containing psychomotor (Bush Francis Catatonia Rating Scale; St Hans Rating Scale; Salpêtrière Retardation Rating Scale; Neurological Evaluation Scale) and clinical (Positive and Negative Syndrome Scale; Calgary Depression Scale) rating scales as well as instrumental psychomotor tests (Line Copying Task; Finger Tapping Task) and cognitive tasks (Symbol Digit Substitution Test; Stroop Colour Word Test; Continuous Performance Test; Letter Number Sequencing) was administered to a sample of 124 patients with schizophrenia or schizoaffective disorder. RESULTS Correlational analyses showed that two clusters emerge from our data: first, a psychomotor poverty cluster referring to the interrelations between catatonia, parkinsonism, psychomotor slowing, and negative symptoms; second, a cluster containing motoric neurological soft signs, which were found to be correlated with cognitive functioning. CONCLUSION Psychomotor abnormalities are highly prevalent phenomena in schizophrenia that have to be considered as a heterogeneous construct. However, longitudinal and neurobiological research is needed to further explore the precise nature of the interrelations found in this study.

Abstract
BACKGROUND Despite a growing scientific and clinical interest in catatonia, its precise definition remains debated. AIM The aim of this study was to offer a systematic review of the different rating scales that have been developed to assess catatonia in clinical practice. METHODS A Medline-search was performed, up to December 2010. RESULTS Seven catatonia rating scales were retrieved: the Modified Rogers Scale, the Rogers Catatonia Scale, the Bush-Francis Catatonia Rating Scale (BFCRS), and its revision, the Northoff Catatonia Rating Scale (NCRS), the Braunig Catatonia Rating Scale (BCRS), and the Kanner Scale. CONCLUSION Several catatonia rating scales are proposed to detect the catatonic syndrome and to evaluate treatment response. BFCRS, NCRS and BCRS are reliable for use in variable populations in which catatonia is prevalent. The BFCRS is preferred for routine use, because of its validity and reliability, and its ease of administration.

Abstract
Prevalence and correlates of primary motor abnormalities in schizophrenia are presently ill defined. This study was aimed at examining the prevalence, syndromic structure, external correlates, and response to antipsychotic medication of a broad array of primary motor abnormalities. Two-hundred antipsychotic-naive patients with schizophrenia spectrum disorders were examined for motor abnormalities using the Modified Rogers Scale. Thirty-one motor signs were subjected to factor analysis, and the resulting factors examined for association with a number of risk factors, clinical and psychopathological variables. One-hundred and eighty-nine patients were reassessed for motor abnormalities after completing a 4-week trial with antipsychotic medication. Prevalence rates for at least one motor sign and syndrome at baseline were 66% and 40%, respectively. Motor signs clustered together into seven clinically interpretable factors: abnormal involuntary movements, hypokinesia, retarded catatonia, echo-phenomena, excited catatonia, catalepsy, and parkinsonism. All motor domains but parkinsonism were inter-related. Abnormal involuntary movements were associated with variables indicating both neurodevelopmental dysfunction and illness severity, and most motor domains were closely related to negative or disorganization symptoms. Change scores in motor domains after treatment with antipsychotic medication indicated improvement for abnormal involuntary movements, hypokinesia, retarded catatonia, excited catatonia and echophenomena, and worsening for parkinsonism. It is concluded that primary motor dysfunction is a prevalent and heterogeneous condition of schizophrenia. Motor abnormalities segregate into various syndromes, which have different clinical correlates and a differential response pattern to antipsychotic medication. It is hypothesized that the existence of a differential dopaminergic dysfunction in the nigroestriatal circuitry is responsible for the generation of those motor domains that improve and worsen with antipsychotic drugs.

Abstract
OBJECTIVE To examine the prevalence, psychometric validity and response to antipsychotic drugs of DSM-IV catatonia signs and criteria in patients with a first-episode psychotic disorder. METHODS Two-hundred antipsychotic-naive patients with a DSM-IV nonaffective psychosis were assessed for catatonia signs and criteria using the Modified Rogers Scale, and the psychometric validity of the 12 DSM-IV catatonia signs and diagnostic criteria was examined. Treatment response of catatonia was assessed in 173 patients who completed one-month trial with haloperidol (n=23), risperidone (n=93) or olanzapine (n=57). RESULTS Sixty-two patients (31%) endorsed at least one catatonia sign and 24 (12%) met DSM-IV criteria for catatonia. DSM-IV catatonia signs showed an excellent convergent validity (r>0.8) with other rating scales, and DSM-IV criteria showed moderate to fair concordance with other criteria (kappa from 0.57 to 0.77). The total number of signs reflected catatonia severity and demonstrated excellent diagnostic performance against alternative diagnostic criteria. The presence of at least any three signs accurately identified patients with catatonia. Three catatonia domains were identified (hyperkinesia, volitional and hypokinesia), which showed a different association pattern with external variables. Overall, catatonia ratings were particularly related to both dyskinesia and disorganization symptoms and lacked diagnostic specificity for schizophrenia. Patients with catatonia responded well to antipsychotic medication irrespective of the type of antipsychotic drug used, although treatment response was dependent upon the remission of psychotic symptoms. CONCLUSIONS These results may inform the DSM-V development on diagnosis and classification of catatonia, and indicate that catatonia signs and syndromes are highly responsive to antipsychotic drugs.

Abstract
To provide a rational basis for reconceptualizing catatonia in Diagnostic and Statistical Manual of Mental Disorders (Fifth Edition), we briefly review historical sources, the psychopathology of catatonia, and the relevance of catatonic schizophrenia in contemporary practice and research. In contrast to Kahlbaum, Kraepelin and others (Jaspers, Kleist, and Schneider) recognized the prevalence of motor symptoms in diverse psychiatric disorders but concluded that the unique pattern and persistence of certain psychomotor phenomena defined a "catatonic" subtype of schizophrenia, based on intensive long-term studies. The enduring controversy and confusion that ensued underscores the fact that the main problem with catatonia is not just its place in Diagnostic and Statistical Manual of Mental Disorders but rather its lack of conceptual clarity. There still are no accepted principles on what makes a symptom catatonic and no consensus on which signs and symptoms constitute a catatonic syndrome. The resulting heterogeneity is reflected in treatment studies that show that stuporous catatonia in any acute disorder responds to benzodiazepines or electroconvulsive therapy, whereas catatonia in the context of chronic schizophrenia is phenomenologically different and less responsive to either modality. Although psychomotor phenomena are an intrinsic feature of acute and especially chronic schizophrenia, they are insufficiently recognized in practice and research but may have significant implications for treatment outcome and neurobiological studies. While devising a separate category of catatonia as a nonspecific syndrome has heuristic value, it may be equally if not more important to re-examine the psychopathological basis for defining psychomotor symptoms as catatonic and to re-establish psychomotor phenomena as a fundamental symptom dimension or criterion for both psychotic and mood disorders.

Abstract
This paper examined outcomes among youth with catatonic syndrome and determined whether the characteristics suggesting the relevance of chronic catatonic schizophrenia (CCS) at index episode remained stable at follow-up. From 1993 to 2004, 35 individuals aged 12 to 18 years were prospectively admitted for management of catatonic syndrome and followed up after discharge. Mean duration from discharge to follow-up was 3.9 years (range 1-10). Four patients were lost to follow-up. Among the remaining 31 subjects (mean age=19.5 years, range 15-26), life-time diagnosis using the Diagnostic Interview for Genetic Studies was unchanged in 28 patients, and included schizophrenia (all subtypes; N=20), major depressive episode (N=5), bipolar disorder type I (N=4) and brief psychotic episode (N=2). Mortality (all-cause Standardized Mortality Ratio=6266; 95% CI=1181-18,547) and morbidity were severe, with 3 deaths (including 2 suicides), 6 patients presenting with a causal organic condition and 14 subjects needing continuous psychiatric care. All males in the study (N=8) who had chronic catatonic schizophrenia at the index episode still had chronic catatonic signs at follow-up. Catatonia is one of the most severe psychiatric syndromes in adolescents. It is associated with a 60-fold increased risk of premature death, including suicide, when compared to the general population of same sex and age. This increased risk of premature death remains higher than the one measured in former adolescent psychiatric patients (all-cause SMR=221; 95% CI=156-303; Engqvist and Rydelius, 2006), or in schizophrenia irrespective to age and subtype (all-cause SMR=157; 95% CI=153-160; Harris and Barraclough, 1998).

Abstract
Although dementia praecox or schizophrenia has been considered a unique disease entity for the past century, its definitions and boundaries have continued to vary over this period. At any given time, the changing concept of schizophrenia has been influenced by available diagnostic tools and treatments, related conditions from which it most needs to be distinguished, extant knowledge and scientific paradigms. There is significant heterogeneity in the etiopathology, symptomatology, and course of schizophrenia. It is characterized by an admixture of positive, negative, cognitive, mood, and motor symptoms whose severity varies across patients and through the course of the illness. Positive symptoms usually first begin in adolescence or early adulthood, but are often preceded by varying degrees of negative and cognitive symptomatology. Schizophrenia tends to be a chronic and relapsing disorder with generally incomplete remissions, variable degrees of functional impairment and social disability, frequent comorbid substance abuse, and decreased longevity. Although schizophrenia may not represent a single disease with a unitary etiology or pathogenetic process, alternative approaches have thus far been unsuccessful in better defining this syndrome or its component entities. The symptomatologic, course, and etio-pathological heterogeneity can usefully be addressed by a dimensional approach to psychopathology, a clinical staging approach to illness course, and by elucidating endophenotypes and markers of illness progression, respectively. This will allow an approach to the deconstruction of schizophrenia into its multiple component parts and strategies to reconfigure these components in a more meaningful manner. Possible implications for DSM-V and ICD-11 definitions of schizophrenia are discussed.

Abstract
No reports have yet been published on catatonia using latent class analysis (LCA). This study applied LCA to a large, diagnostically homogenous sample of patients with chronic schizophrenia who also presented with catatonic symptoms. A random sample of 225 Chinese inpatients with DSM-IV schizophrenia was selected from the long-stay wards of a psychiatric hospital. Their psychopathology, extrapyramidal motor status and level of functioning were evaluated with standardized rating scales. Catatonia was rated using a modified version of the Bush-Francis Catatonia Rating Scale. LCA was then applied to the 178 patients who presented with at least one catatonic sign. In LCA a four-class solution was found to fit best the statistical model. Classes 1, 2, 3 and 4 constituted 18%, 39.4%, 20.1% and 22.5% of the whole catatonic sample, respectively. Class 1 included patients with symptoms of 'automatic' phenomena (automatic obedience, Mitgehen, waxy flexibility). Class 2 comprised patients with 'repetitive/echo' phenomena (perseveration, stereotypy, verbigeration, mannerisms and grimacing). Class 3 contained patients with symptoms of 'withdrawal' (immobility, mutism, posturing, staring and withdrawal). Class 4 consisted of 'agitated/resistive' patients, who displayed symptoms of excitement, impulsivity, negativism and combativeness. The symptom composition of these 4 classes was nearly identical with that of the four factors identified by factor analysis in the same cohort of subjects in an earlier study. In multivariate regression analysis, the 'withdrawn' class was associated with higher scores on the Scale of Assessment of Negative Symptoms and lower and higher scores for negative and positive items respectively on the Nurses' Observation Scale for Inpatient Evaluation's (NOSIE). The 'automatic' class was associated with lower values on the Simpson-Angus Extrapyramidal Side Effects Scale, and the 'repetitive/echo' class with higher scores on the NOSIE positive items. These results provide preliminary support for the notion that chronic schizophrenia patients with catatonic features can be classified into 4 distinct syndromal groups on the basis of their motor symptoms. Identifying distinct catatonic syndromes would help to find their biological substrates and to develop specific therapeutic measures.
