BACKGROUND
Selective mutism (SM) is a childhood onset anxiety disorder, and the main symptom is not speaking in certain social situations. Knowledge about the duration and long-term outcomes of SM have been lacking and the aim of this systematic literature review was to address this gap in the literature. We investigated how long SM symptoms persisted as well as other psychiatric outcomes associated with SM in later life.
METHODS
The PubMed, PsycInfo, Web of Science, Cochrane Library and Embase databases were initially searched from inception to 11 September 2023. Studies were included if they were published in English and had followed up subjects with clinically diagnosed SM for at least two years. The review followed the Preferred Reporting Items of Systematic Reviews and Meta-analyses guidelines and the protocol was registered with the Open Science Framework. The papers were assessed using the Quality Assessment with Diverse Studies tool.
RESULTS
This review screened 2,432 papers and assessed 18 studies. Seven case series studies were excluded from discussion because of the low number of subjects and the fact that their findings could not be generalized to wider populations. In the end, nine clinical cohorts and two case control studies were reviewed. These provided a total of 292 subjects and the sample sizes ranged from 11-49. The overall quality of the studies was moderate. The review found that 190 of the 243 subjects in the studies that reported recovery rates showed moderate or total improvement from SM during follow up. Other anxiety disorders were the most common psychiatric disorders later in life, although these results should be interpreted with caution. Older age at baseline and parental psychopathology might predict greater impairment, but further studies are needed to confirm these results.
CONCLUSIONS
Most subjects with SM recovered from this disorder during adolescence, but anxiety disorders were common in later life. Early detection and treatment are needed to prevent symptoms from persisting and other psychiatric disorders from developing.

BACKGROUND
Catatonia is an underdiagnosed and undertreated neuropsychiatric syndrome characterized by catalepsy, negativism, mutism, muscular rigidity, and mannerism, often accompanied by autonomic instability and fever. Although there is growing interest in studying cognitive impairments before and after catatonia, little is known about the cognitive features of the syndrome.
METHODS
This systematic review was registered at PROSPERO (CRD42022299091). Using a Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) approach, we searched PubMed, ScienceDirect, and PsycArticles using a combination of the terms "Catatonia" and "Cognitive impairment" and "Executive function" and "Frontal lobe" and "Parietal lobe." Studies included original research articles enrolling patients with catatonic syndrome according to specified criteria. Fourteen studies were deemed relevant for inclusion. The abstraction form included age, assessment during acute episode, associated diagnosis, assessment procedure, and cognitive domains. Outcome measures were extracted.
RESULTS
Executive functions and visuospatial abilities proved to be the most investigated domains. A great heterogeneity has been observed in the assessment tools used among the 14 evaluated studies. Findings showed that catatonic patients had worse performance than healthy and non-catatonic psychiatric patients in frontal and parietal cortical functions.
CONCLUSION
Because of the small number of studies in such heterogeneous areas and significant methodological limitations, the results should be regarded with caution. Future research assessing cognitive impairments on catatonic patients is needed.

Identifying complementary and alternative medicine recommendations for anxiety treatment and care: a systematic review and critical assessment of comprehensive clinical practice guidelines.
BACKGROUND
Clinical practice guidelines (CPGs) are used to guide decision-making, especially regarding complementary and alternative medicine (CAM) therapies that are unfamiliar to orthodox healthcare providers. This systematic review aimed to critically review and summarise CAM recommendations associated with anxiety management included in the existing CPGs.
METHODS
Seven databases, websites of six international guidelines developing institutions, and the website were systematically searched. Their reporting and methodological quality were evaluated using the checklist and the (2nd version) instrument, respectively.
RESULTS
Ten CPGs were included, with reporting rates between 51.4 and 88.6%. Seven of these were of moderate to high methodological quality. Seventeen CAM modalities were implicated, involving phytotherapeutics, mind-body practice, art therapy, and homeopathy. Applied relaxation was included in 70% CPGs, which varied in degree of support for its use in the treatment of generalised anxiety disorder. There were few recommendations for other therapies/products. Light therapy was not recommended for use in generalised anxiety disorder, and and mindfulness were not recommended for use in social anxiety disorder in individual guidelines. Recommendations for the applicability of other therapies/products for treating a specific anxiety disorder were commonly graded as "unclear, unambiguous, or uncertain". No CAM recommendations were provided for separation anxiety disorder, specific phobia or selective mutism.
CONCLUSION
Available guidelines are limited in providing logically explained graded CAM recommendations for anxiety treatment and care. A lack of high-quality evidence and multidisciplinary consultation during the guideline development are two major reasons. High quality and reliable clinical evidence and the engagement of a range of interdisciplinary stakeholders are needed for future CPG development and updating.

BACKGROUND
Selective mutism (SM) is an anxiety disorder that often starts in early years with serious and lasting consequences. Nonpharmacological interventions are commonly seen as the preferred first treatment. This systematic review identifies outcome measures used and outcomes achieved for nonpharmacological interventions for children and adolescents with SM.
METHODS
Systematic searches were conducted using 13 electronic databases and hand searches, including peer-reviewed and grey literature since 1992.
RESULTS
Twenty-five studies were identified. While specific measures varied, all studies reported an outcome measure for speaking behaviour and 18 used a measure of anxiety. Few studies reported measures of SM remission ( = 6), well-being ( = 6), academic impact ( = 2), or quality of life ( = 1). Within subject outcomes for nonpharmacological interventions were variable for improvements in speaking behaviours (very small to large positive effects) and reduction in anxiety symptoms (very small negative to large positive effects). Only five randomised controlled trials (RCTs) were included in the meta-analysis. Three studies compared a combined systems/behavioural approach with waitlist controls indicating a significant and large effect (Hedges = 1.06, < .0001, 95% CI: 0.57-1.56) on improved speaking behaviour. Two of these RCTs showed a large effect for SM remission favouring the intervention (Risk Ratio = 4.25, = .1774, 95% CI: 0.52-34.84) but this did not reach statistical significance. Non-significant outcomes for two RCTs with active controls (Hedges = 0.55, < .2885, 95% CI: -0.47 to 1.57) showed considerable heterogeneity in approach and outcomes, one with large and one with negligible effects.
CONCLUSION
Despite the considerable impairment caused by SM, there has been little systematic evaluation of non-pharmacological interventions. Although combined systems/behavioural interventions are promising, further systematic evaluations are urgently needed to inform treatment approaches. Cross-study measurement harmonisation is required to promote learning from all studies, including wider clinical and economic outcomes.

Review
Selective mutism is a childhood psychiatric disorder that has been associated with adverse psychological, social and educational outcomes. Although evidence suggests that culturally and linguistically diverse children might be overrepresented among children with selective mutism, a direct examination of how migration or minority status are associated with the development and persistence of the disorder is still scarce. Guided by eco-cultural perspectives of development, the current review aims to provide an overview of selective mutism in culturally and linguistically diverse children. A systematic literature review of selective mutism studies that included a group of culturally and linguistically diverse children yielded eight studies that met our inclusion criteria. Although these studies support the view that bilingualism and minority status might be associated with selective mutism, the role of sociocultural factors in the development and persistence of the disorder remained mostly unexamined. The review concludes with a discussion of potential directions for future research, including examination of the cultural and psychological meanings of silence and talk, socialization goals, gender inequality, and parental acculturation strategies.

Review
INTRODUCTION
Neuroleptic malignant syndrome (NMS) is a rare and potentially fatal drug adverse reaction. There are still few studies of this entity in the child-adolescent population.
OBJECTIVES
Describe the clinical, laboratory and therapeutic characteristics of children and adolescent patients with NMS. Analyse the grouping of symptoms present in NMS in the same population.
MATERIAL AND METHODS
A MEDLINE/PubMed search of all reported cases of NMS from January 2000 to November 2018 was performed and demographic, clinical, laboratory and therapeutic variables were identified. A factorial analysis of the symptoms was performed.
RESULTS
57 patients (42 males and 15 females) were included, (mean age 13.65±3.89 years). The onset of NMS occurred at 11.25±20.27 days with typical antipsychotics and at 13.69±22.43 days with atypical antipsychotics. The most common symptoms were muscle stiffness (84.2%), autonomic instability (84.2%) and fever (78.9). The most common laboratory findings were CPK elevation and leucocytosis (42.1%). The most used treatment was benzodiazepines (28.1%). In the exploratory factorial analysis of the symptoms we found 3factors: 1) "Catatonic" with mutism (0.912), negativism (0.825) and waxy flexibility (0.522); 2) "Extrapyramidal" with altered gait (0.860), involuntary abnormal movements (0.605), muscle stiffness (0.534) and sialorrhoea (0.430); and 3) "Autonomic instability" with fever (0.798), impaired consciousness (0.795) and autonomic instability (0.387).
CONCLUSIONS
NMS in children and adolescents could be of 3types: catatonic, extrapyramidal and autonomic unstable.

Review
INTRODUCTION
Catatonia is classically associated with psychiatric conditions but may occur in medical and neurologic disorders. Status epilepticus (SE) is a seizure lasting more than five minutes or two or more seizures within a five-minute period without interictal recovery of consciousness. Non-convulsive status epilepticus (NCSE) is SE without prominent motor activity that may present with catatonic symptoms. The relevance of NCSE as a potential etiology for catatonia is not clear in the literature.
METHODS
A systematic review was completed to evaluate the literature on NCSE presenting with catatonia. PubMed and PsycInfo databases were searched and articles were reviewed for the presence of catatonia and NCSE.
RESULTS
15 articles describing 27 cases meeting inclusion criteria were identified. The authors add 1 case to the literature. The most common catatonic symptoms identified in NCSE were mutism and stupor. Clinical features frequent in NCSE presenting with catatonia included new catatonic symptoms, age over 50 years, comorbid neurological conditions, or a change in medications that affect seizure threshold. A documented psychiatric history was also common and may contribute to delayed diagnosis.
DISCUSSION/CONCLUSION
It is important to consider NCSE in the differential diagnosis of new catatonic symptoms. A suggested approach to diagnostic evaluation is provided.

Meta-Analysis Review
OBJECTIVE
A review article assessing all the risk factors reported in the literature for postoperative cerebellar mutism syndrome (pCMS) among children remains absent. The authors sought to perform a systematic review and meta-analysis to evaluate this issue.
METHODS
PubMed, Embase, and Web of Science were queried to systematically extract potential references. The articles relating to pCMS were required to be written in the English language, involve pediatric patients (≤ 18 years of age), and provide extractable data, which included a comparison group of patients who did not develop pCMS. The quality of the included studies was evaluated using the Newcastle-Ottawa Scale. Data were pooled using RevMan 5.4, and publication bias was assessed by visual inspection for funnel plot asymmetry. The study protocol was registered through PROSPERO (ID: CRD42021256177).
RESULTS
Overall, 28 studies involving 2276 patients were included. Statistically significant risk factors identified from univariate analysis were brainstem invasion (OR 4.28, 95% CI 2.23-8.23; p < 0.0001), fourth ventricle invasion (OR 12.84, 95% CI 4.29-38.44; p < 0.00001), superior cerebellar peduncle invasion (OR 6.77, 95% CI 2.35-19.48; p = 0.0004), diagnosis of medulloblastoma (OR 3.26, 95% CI 1.93-5.52; p < 0.0001), medulloblastoma > 50 mm (OR 8.85, 95% CI 1.30-60.16; p = 0.03), left-handedness (OR 6.57, 95% CI 1.25-34.44; p = 0.03), and a vermis incision (OR 5.44, 95% CI 2.09-14.16; p = 0.0005). On the other hand, a tumor located in the cerebellar hemisphere (OR 0.23, 95% CI 0.06-0.92; p = 0.04), cerebellar hemisphere compression (OR 0.23, 95% CI 0.11-0.45; p < 0.0001), and intraoperative imaging (OR 0.36, 95% CI 0.18-0.72; p = 0.004) reduced the risk of pCMS.
CONCLUSIONS
This study provides the largest and most reliable review of risk factors associated with pCMS. Although some risk factors may be dependent on one another, the data may be used by surgeons to better identify patients at risk for pCMS and for intervention planning.

Review
BACKGROUND
Anxiety disorders are highly prevalent and cause significant distress, disability, and cost. Medication adverse effects and interactions increase in mid-life and late-life, highlighting the need for effective non-pharmacological interventions.
OBJECTIVES
We aimed to evaluate the extent of evidence supporting exercise interventions for anxiety and subthreshold anxiety disorders in mid-life and late-life.
DESIGN
Systematic review.
DATA SOURCES AND METHODS
We searched MEDLINE, PsycINFO, Embase, Emcare, Ovid Nursing, CINAHL Plus, Cochrane Library, Health Collection, Humanities & Social Sciences Collection, and https://clinicaltrials.gov databases for trials published January 1994-May 2019. Randomised controlled trials of exercise interventions involving aerobic exercise or resistance training for adults aged 40 years and above with anxiety or subthreshold anxiety disorders in residential or health settings were identified. The primary outcome was change in anxiety. We excluded trials including participants aged below 40 years, participants with diagnosis of separation anxiety, selective mutism, obsessive-compulsive disorder, acute stress disorder and post-traumatic stress disorder, and head-to-head comparisons of interventions. Trial quality was assessed using the Cochrane Risk of Bias Tool and evidence synthesised in narrative form.
RESULTS
Four trials totalling 132 participants met inclusion criteria, although some had methodological limitations. Interventions included a home-based resistance training intervention, supervised group-based aerobic intervention, Tai Chi intervention, and supervised group-based aerobic and strength intervention. Three trials included late-life participants and the fourth mid-life. Three trials demonstrated greater reductions in anxiety in the intervention group compared with control. The fourth trial showed pre-post reductions in anxiety in both groups, with between-group difference not reaching statistical significance.
CONCLUSION
There is limited supportive evidence suggesting that exercise interventions have potential to be effective, feasible and safe non-pharmacological interventions for anxiety and subthreshold anxiety disorders in mid-life and late-life. The heterogeneity, limited number and high risk of bias of some trials meant that we were not able to conduct a meta-analysis. Tailoring of interventions may improve uptake and reduce dropout. The paucity of research in this area with only four included trials demonstrates the urgent need for future and larger trials to provide proof of concept, data about effective types and doses of exercise interventions, and guidance to community, clinical, and public health services.

Review
BACKGROUND
Supplementary motor area syndrome (SMAS) may occur after frontal tumor surgery, with variable presentation and outcomes. We reviewed the literature on postoperative SMAS after brain tumor resection.
METHODS
PubMed, Web of Science, Scopus, and Cochrane were searched following the PRISMA guidelines to include studies reporting SMAS after brain tumor resection.
RESULTS
We included 31 studies encompassing 236 patients. Most tumors were gliomas (94.5%), frequently of low grade (61.4%). Most lesions were located on the left hemisphere (64.4%), involving the supplementary motor area (61.4%) and the cingulate gyrus (20.8%). Tractography and functional magnetic resonance imaging evaluation were completed in 45 (19.1%) and 26 (11%) patients. Gross total resection was achieved in 46.3% patients and complete SMA resection in 69.4%. A total of 215 procedures (91.1%) used intraoperative neuromonitoring mostly consisting of direct cortical/subcortical stimulation (56.4%), motor (33.9%), and somatosensory (25.4%) evoked potentials. Postoperative SMAS symptoms occurred within 24 hours after surgery, characterized by motor deficits (97%), including paresis (68.6%) and hemiplegia (16.1%), and speech disorders (53%), including hesitancy (24.2%) and mutism (22%). Average SMAS duration was 45 days (range, 1-365 days), with total resolution occurring in 188 patients (79.7%) and partial improvement in 46 (19.5%). Forty-eight patients (20.3%) had persisting symptoms, mostly speech hesitancy (60.4%) and fine motor disorders (45.8%).
CONCLUSIONS
Postoperative SMAS may occur within the first 24 hours after mesial frontal tumor surgery. Preoperative mapping and intraoperative neuromonitoring may assist resection and predict outcomes. Neuroplasticity and interhemispheric connectivity play a major role in resolution.
