Abstract
There are no well-validated treatments for functional seizures. While specialist psychotherapy is usually recommended, the evidence for its benefit is qualified, and it can be difficult to obtain. Given the association between hyperventilation and functional seizures we explored an alternative modality, breathing control training, in a multi-site open label pilot trial. Participants with functional seizures over the age of 16 received an hour of breathing training from a respiratory physiotherapist, with a half-hour booster session a month later. Seizure frequency and Nijmegen scores (a measure of hyperventilation) were reported at baseline and follow-up, 3-4 months later. Eighteen subjects were recruited, and 10 completed follow-up. Seven of these 10 had improved seizure frequency, and 3 did not (Wilcoxon signed rank test, p = 0.09), with seizure frequency correlating with Nijmegen score (Spearman's rank correlation = 0.75, p = 0.034). The intervention was well tolerated, with no adverse events reported. These preliminary results support a potentially new approach to treating functional seizures that should prove cost-effective and acceptable, though require confirmation by a randomised controlled trial.

Abstract
Functional neurological disorder (FND), formerly called conversion disorder, is a condition characterized by neurological symptoms that lack an identifiable organic purpose. These signs, which can consist of motor, sensory, or cognitive disturbances, are not deliberately produced and often vary in severity. Its diagnosis is predicated on clinical evaluation and the exclusion of other medical or psychiatric situations. Its treatment typically involves a multidisciplinary technique addressing each of the neurological symptoms and underlying psychological factors via a mixture of medical management, psychotherapy, and supportive interventions. Recent advances in neuroimaging and a deeper exploration of its epidemiology, pathophysiology, and clinical presentation have shed new light on this disorder. This paper synthesizes the current knowledge on FND, focusing on its epidemiology and underlying mechanisms, neuroimaging insights, and the differentiation of FND from feigning or malingering. This review highlights the phenotypic heterogeneity of FND and the diagnostic challenges it presents. It also discusses the significant role of neuroimaging in unraveling the complex neural underpinnings of FND and its potential in predicting treatment response. This paper underscores the importance of a nuanced understanding of FND in informing clinical practice and guiding future research. With advancements in neuroimaging techniques and growing recognition of the disorder's multifaceted nature, the paper suggests a promising trajectory toward more effective, personalized treatment strategies and a better overall understanding of the disorder.

Abstract
OBJECTIVE Functional neurological disorder (FND) involves the presence of neurological symptoms that cannot be explained by neurological disease. FND has long been linked to hypnosis and suggestion, both of which have been used as treatments. Given ongoing interest, this review examined evidence for the efficacy of hypnosis and suggestion as treatment interventions for FND. METHOD A systematic search of bibliographic databases was conducted to identify group studies published over the last hundred years. No restrictions were placed on study design, language, or clinical setting. Two reviewers independently assessed papers for inclusion, extracted data, and rated study quality. RESULTS The search identified 35 studies, including 5 randomised controlled trials, 2 non-randomised trials, and 28 pre-post studies. Of 1584 patients receiving either intervention, 1379 (87%) showed significant improvements, including many who demonstrated resolution of their symptoms in the short-term. Given the heterogeneity of interventions and limitations in study quality overall, more formal quantitative synthesis was not possible. CONCLUSIONS The findings highlight longstanding and ongoing interest in using hypnosis and suggestion as interventions for FND. While the findings appear promising, limitations in the evidence base, reflecting limitations in FND research more broadly, prevent definitive recommendations. Further research seems warranted given these supportive findings.

Abstract
Occupational therapy (OT) is an important treatment modality for patients with paroxysmal functional neurologic disorder (FND) symptoms. In our clinical experience, an outpatient, OT-based sensory modulation treatment can address sensory processing difficulties often endorsed by patients with paroxysmal motor FND and functional seizures. This article aims to describe in detail the goals and treatment strategies for occupational therapists to replicate this approach. This article is also an important first step in aiding the development and execution of clinical trials to further evaluate the effectiveness of sensory-based treatment in patients with FND.

Abstract
Functional Neurological Disorders - A Common but Often Unrecognized Diagnosis Abstract: Functional neurological disorders are frequent and diverse in the clinical presentation. Psychological factors are part of the development and perpetuation of symptoms; psychiatric comorbidities may be present, but are not an obligatory diagnostic criterion. The diagnosis is primarily made on the basis of anamnesis and positive clinical signs. The commonness and reversibility of the symptoms should be emphasised in the clinical consultation, and the positive clinical signs should be demonstrated. Science-based explanations as well as the bio-psycho-social model can help patients to understand their diagnosis, which is relevant for a successful therapeutic outcome. It is recommended to use the neutral and descriptive term "functional neurological disorder". Treatment of the potentially reversible disease will be interdisciplinary and multimodal.

Abstract
LEARNING OBJECTIVES • Develop and implement treatment plans for children and adolescents with functional neurological disorder (FND)• Outline a plan to increase awareness and standardize the care for patients with FND using evidence-based interventions. ABSTRACT Functional neurological disorder (FND) in children and adolescents involves the biological embedding of lived experience in the body and brain. This embedding culminates in stress-system activation or dysregulation and in aberrant changes in neural network function. In pediatric neurology clinics, FND represents up to one-fifth of patients. Current research shows good outcomes with prompt diagnosis and treatment using a biopsychosocial, stepped-care approach. At present, however-and worldwide-FND services are scarce, the result of long-standing stigma and ingrained belief that patients with FND do not suffer from a real ("organic") disorder and that they therefore do not require, or even deserve, treatment. Since 1994, the Mind-Body Program for children and adolescents with FND at The Children's Hospital at Westmead in Sydney, Australia-run by a consultation-liaison team-has delivered inpatient care to hundreds of patients with FND and outpatient care to hundreds of others. For less-disabled patients, the program enables community-based clinicians to implement biopsychosocial interventions locally by providing a positive diagnosis (by a neurologist or pediatrician), a biopsychosocial assessment and formulation (by clinicians from the consultation-liaison team), a physical therapy assessment, and clinical support (from the consultation-liaison team and the physiotherapist). In this Perspective we describe the elements of a biopsychosocial mind-body program intervention capable of providing, as needed, effective treatment to children and adolescents with FND. Our aim is to communicate to clinicians and institutions around the world what is needed to establish effective community treatment programs, as well as hospital inpatient and outpatient interventions, in their own health care settings.

Abstract
Functional neurological disorder (FND) is a common issue in the pediatric population. The concept and our understanding of functional neurological disorders have changed over the past years, and new etiologic models and treatment plans have been explored. Knowledge about FND in the pediatric population, however, is lacking. The aim of this review is to provide an update on pediatric functional neurological disorder. We conducted a literature search of PubMed and SCOPUS databases and reviewed a total of 85 articles to gain insight into the current understanding of FND etiology, diagnosis, treatment, and prognosis in children and adolescents. Functional and high resolution MRI revealed abnormal connectivity and structural changes in patients with functional symptoms. The diagnostic criteria no longer require the presence of a psychological factor and instead focus on a rule-in diagnosis. Treatment of FND includes a clear communication of the diagnosis and the support of a multidisciplinary team. Although FND typically has a poor prognosis, better outcomes appear to have been achieved in children and young adults. We conclude that pediatric functional neurological disorder is a prevalent pathology and that this patient population has additional specific needs compared to the adult population.

Abstract
A 37-year-old woman was referred to a Center for Special Dentistry (CBT) because she could not be treated in home practice. A conversion disorder, or functional neurologic symptom disorder, was diagnosed five years ago. This refers to unplanned movements and symptoms that can't be explained by a neurological or other somatic disorder. In this patient, it manifests itself in difficulty in swallowing and tolerating very little water or food in the mouth. The patient is afraid that the conversion disorder will not be taken seriously during the dental treatments. That is why the patient asked the CBT dentist to take this into account and teach her some tricks for the conversion disorder, so that she can eventually be treated again in the general dental practice. This case serves as an example to discuss the problems related to dental treatment of patients with a serious mental illness.

Abstract
BACKGROUND Functional neurological disorders (FNDs) are common but often misdiagnosed. REVIEW SUMMARY The incidence of FNDs is between 4 and 12 per 100,000, comparable to multiple sclerosis and amyotrophic lateral sclerosis, and it is the second most common diagnosis in neurology clinics. Some clues in the history are sudden onset, intermittent time course, variability of manifestation over time, childhood trauma, and history of other somatic symptoms. Anxiety and depression are common, but not necessarily more than in the general population. Although there are no tests currently capable of demonstrating whether symptoms are willfully produced, there may not be a clear categorical difference between voluntary and involuntary symptoms. The prognosis of an FND is linked to early diagnosis and symptom duration, but unfortunately, the majority of the patients are diagnosed after considerable delays. CONCLUSIONS A positive diagnosis of FNDs can be made on the basis of history and neurological signs without reliance on psychological stressors. Past sensitizing events and neurobiological abnormalities contribute to the pathogenesis of FNDs. Physical rehabilitation and psychological interventions alone or in combination are helpful in the treatment.

Abstract
PURPOSE OF REVIEW Psychogenic nonepileptic seizures (PNES) are the most common Functional Neurological Disorder/Conversion Disorder subtype. Significant advances have been made related to diagnosis, neurobiology, and treatment. In this review, we summarize updates in diagnosis and management over the past 3 years. RECENT FINDINGS Although evidence is mixed for the treatment of PNES, psychotherapeutic modalities remain a powerful instrument to empower patients and reduce seizures. A multidisciplinary, holistic approach is beneficial. While seizure freedom in all patients may not be the achieved endpoint in this chronic, paroxysmal disorder, quality of life can be improved with treatment. Additional treatment modalities and further research are needed for patients who are refractory to current treatment. Evidence-based therapies exist for PNES, and recent findings represent an increased understanding of the clinical and neurophysiologic aspects of PNES.

Abstract
Functional neurological disorder (FND), previously regarded as a diagnosis of exclusion, is now a rule-in diagnosis with available treatments. This represents a major step toward destigmatizing the disorder, which was often doubted and deemed untreatable. FND is prevalent, generally affecting young and middle aged adults, and can cause severe disability in some individuals. An early diagnosis, with subsequent access to evidence based rehabilitative and/or psychological treatments, can promote recovery-albeit not all patients respond to currently available treatments. This review presents the latest advances in the use of validated rule-in examination signs to guide diagnosis, and the range of therapeutic approaches available to care for patients with FND. The article focuses on the two most frequently identified subtypes of FND: motor (weakness and/or movement disorders) and seizure type symptoms. Twenty two studies on motor and 27 studies on seizure type symptoms report high specificities of clinical signs (64-100%), and individual signs are reviewed. Rehabilitative interventions (physical and occupational therapy) are treatments of choice for functional motor symptoms, while psychotherapy is an emerging evidence based treatment across FND subtypes. The literature to date highlights heterogeneity in responses to treatment, underscoring that more research is needed to individualize treatments and develop novel interventions.

Abstract
Communication problems (eg, dysphonia, dysfluency and language and articulation disorders), swallowing disorders (dysphagia and globus), cough and upper airway symptoms, resulting from functional neurological disorder (FND), are commonly encountered by speech and language professionals. However, there are few descriptions in the literature of the most effective practical management approaches. This consensus document aims to provide recommendations for assessment and intervention that are relevant to both adults and young people. An international panel of speech and language professionals with expertise in FND were approached to take part. Participants responded individually by email to a set of key questions regarding best practice for assessment and interventions. Next, a video conference was held in which participants discussed and debated the answers to these key questions, aiming to achieve consensus on each issue. Drafts of the collated consensus recommendations were circulated until consensus was achieved. FND should be diagnosed on the basis of positive clinical features. Speech and language therapy for FND should address illness beliefs, self-directed attention and abnormal movement patterns through a process of education, symptomatic treatment and cognitive behavioural therapy within a supportive therapeutic environment. We provide specific examples of these strategies for different symptoms. Speech and language professionals have a key role in the management of people with communication and related symptoms of FND. It is intended that these expert recommendations serve as both a practical toolkit and a starting point for further research into evidence-based treatments.

Abstract
BACKGROUND Conversion and dissociative disorders are conditions where people experience unusual neurological symptoms or changes in awareness or identity. However, symptoms and clinical signs cannot be explained by a neurological disease or other medical condition. Instead, a psychological stressor or trauma is often present. The symptoms are real and can cause significant distress or problems with functioning in everyday life for the people experiencing them. OBJECTIVES To assess the beneficial and harmful effects of psychosocial interventions of conversion and dissociative disorders in adults. SEARCH METHODS We conducted database searches between 16 July and 16 August 2019. We searched Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, and eight other databases, together with reference checking, citation searching and contact with study authors to identify additional studies. SELECTION CRITERIA: We included all randomised controlled trials that compared psychosocial interventions for conversion and dissociative disorders with standard care, wait list or other interventions (pharmaceutical, somatic or psychosocial). DATA COLLECTION AND ANALYSIS: We selected, quality assessed and extracted data from the identified studies. Two review authors independently performed all tasks. We used standard Cochrane methodology. For continuous data, we calculated mean differences (MD) and standardised mean differences (SMD) with 95% confidence interval (CI). For dichotomous outcomes, we calculated risk ratio (RR) with 95% CI. We assessed and downgraded the evidence according to the GRADE system for risk of bias, imprecision, indirectness, inconsistency and publication bias. MAIN RESULTS We included 17 studies (16 with parallel-group designs and one with a cross-over design), with 894 participants aged 18 to 80 years (female:male ratio 3:1). The data were separated into 12 comparisons based on the different interventions and comparators. Studies were pooled into the same comparison when identical interventions and comparisons were evaluated. The certainty of the evidence was downgraded as a consequence of potential risk of bias, as many of the studies had unclear or inadequate allocation concealment. Further downgrading was performed due to imprecision, few participants and inconsistency. There were 12 comparisons for the primary outcome of reduction in physical signs. Inpatient paradoxical intention therapy compared with outpatient diazepam: inpatient paradoxical intention therapy did not reduce conversive symptoms compared with outpatient diazepam at the end of treatment (RR 1.44, 95% CI 0.91 to 2.28; 1 study, 30 participants; P = 0.12; very low-quality evidence). Inpatient treatment programme plus hypnosis compared with inpatient treatment programme: inpatient treatment programme plus hypnosis did not reduce severity of impairment compared with inpatient treatment programme at the end of treatment (MD -0.49 (negative value better), 95% CI -1.28 to 0.30; 1 study, 45 participants; P = 0.23; very low-quality evidence). Outpatient hypnosis compared with wait list: outpatient hypnosis might reduce severity of impairment compared with wait list at the end of treatment (MD 2.10 (higher value better), 95% CI 1.34 to 2.86; 1 study, 49 participants; P < 0.00001; low-quality evidence). Behavioural therapy plus routine clinical care compared with routine clinical care: behavioural therapy plus routine clinical care might reduce the number of weekly seizures compared with routine clinical care alone at the end of treatment (MD -21.40 (negative value better), 95% CI -27.88 to -14.92; 1 study, 18 participants; P < 0.00001; very low-quality evidence). Cognitive behavioural therapy (CBT) compared with standard medical care: CBT did not reduce monthly seizure frequency compared to standard medical care at end of treatment (RR 1.56, 95% CI 0.39 to 6.19; 1 study, 16 participants; P = 0.53; very low-quality evidence). CBT did not reduce physical signs compared to standard medical care at the end of treatment (MD -4.75 (negative value better), 95% CI -18.73 to 9.23; 1 study, 61 participants; P = 0.51; low-quality evidence). CBT did not reduce seizure freedom compared to standard medical care at end of treatment (RR 2.33, 95% CI 0.30 to 17.88; 1 trial, 16 participants; P = 0.41; very low-quality evidence). Psychoeducational follow-up programmes compared with treatment as usual (TAU): no study measured reduction in physical signs at end of treatment. Specialised CBT-based physiotherapy inpatient programme compared with wait list: no study measured reduction in physical signs at end of treatment. Specialised CBT-based physiotherapy outpatient intervention compared with TAU: no study measured reduction in physical signs at end of treatment. Brief psychotherapeutic intervention (psychodynamic interpersonal treatment approach) compared with standard care: brief psychotherapeutic interventions did not reduce conversion symptoms compared to standard care at end of treatment (RR 0.12, 95% CI 0.01 to 2.00; 1 study, 19 participants; P = 0.14; very low-quality evidence). CBT plus adjunctive physical activity (APA) compared with CBT alone: CBT plus APA did not reduce overall physical impacts compared to CBT alone at end of treatment (MD 5.60 (negative value better), 95% CI -15.48 to 26.68; 1 study, 21 participants; P = 0.60; very low-quality evidence). Hypnosis compared to diazepam: hypnosis did not reduce symptoms compared to diazepam at end of treatment (RR 0.69, 95% CI 0.39 to 1.24; 1 study, 40 participants; P = 0.22; very low-quality evidence). Outpatient motivational interviewing (MI) and mindfulness-based psychotherapy compared with psychotherapy alone: psychotherapy preceded by MI might decrease seizure frequency compared with psychotherapy alone at end of treatment (MD 41.40 (negative value better), 95% CI 4.92 to 77.88; 1 study, 54 participants; P = 0.03; very low-quality evidence). The effect on the secondary outcomes was reported in 16/17 studies. None of the studies reported results on adverse effects. In the studies reporting on level of functioning and quality of life at end of treatment the effects ranged from small to no effect. AUTHORS' CONCLUSIONS The results of the meta-analysis and reporting of single studies suggest there is lack of evidence regarding the effects of any psychosocial intervention on conversion and dissociative disorders in adults. It is not possible to draw any conclusions about potential benefits or harms from the included studies.

Abstract
PURPOSE We investigated neurologists' experience of participating in the large CODES trial involving around 900 adults with dissociative seizures which subsequently evaluated the effectiveness of tailored cognitive behavioural therapy (CBT) plus standardised medical care versus standardised medical care alone in 368 patients with dissociative seizures. METHOD We asked all neurologists referring patients with dissociative seizures to the CODES study to complete a 43-item online survey. This examined neurologists' (i) demographics, (ii) knowledge of dissociative seizures before and after their involvement in the CODES trial, (iii) clinical practice before, during and since their involvement, and (iv) their experience of the CODES trial. RESULTS Forty-three (51%) neurologists completed the questionnaire. Only about half of neurologists could make referrals to psychological intervention specific for dissociative seizures before and after the trial. One-third of doctors reported having changed their referral practice following their involvement. The majority (>69%) agreed that patient satisfaction with different aspects of the trial was very high, and 83.7% thought that it was easy to recruit patients for the study. Over 90% agreed they would like the treatment pathway to continue. Respondents found different elements of the trial useful, in particular, the patient factsheet booklet (98%), diagnosis communication advice (93%) and the CBT package (93%). CONCLUSIONS Neurologists participating in CODES generally found it easy to recruit patients and perceived patient satisfaction as very high. However, 46.5% of neurologists could not offer psychotherapy once the trial had finished, suggesting that problems with lack of access to psychological treatment for dissociative seizures persist.

Abstract
AIM To describe a cognitive-behavioural treatment and clinical outcomes in a series of children with functional neurological symptoms (FNS). METHOD Thirty-six children with FNS were assessed and of these twenty-two (13 male, 9 female) with a mean age 14.5 years (SD = 2.6, range 6-17 years) completed treatment with cognitive behaviour therapy embedded in routine child and adolescent clinical/systemic practice. Treatment outcomes were measured at baseline and post-intervention on the Child Global Assessment Scale (CGAS), Strengths and Difficulties Questionnaire (SDQ), Goal Based Outcomes (GBO) and Revised Child Anxiety and Depression Scale (RCADS). RESULTS Scores on the CGAS improved significantly post-intervention (p < 0.001) with 82% of participants showing reliable change. Individualised goals (GBO) also showed clinically meaningful gains. Standard measures of emotional and behavioural symptoms (SDQ and RCADS) did not correlate well with clinical diagnoses, were usually subthreshold at baseline, and did not show significant improvement post-intervention. INTERPRETATION The outcome of this pilot study suggests that CBT can be effective in the rehabilitation of young patients with FNS. Detection of common comorbid psychiatric disorders was not assisted by use of standardised measures, although most participants were clinically anxious or depressed. More research is needed to understand why children with FNS and their parents may not endorse mental health symptoms on questionnaires, and to further evaluate interventions within randomised controlled trials.

Abstract
BACKGROUND Conversion disorder is a challenge for clinicians due to the conceptual gaps as regards its pathogenesis, the way in which it converges with other psychiatric disorders, and the lack of approaches to the experiences of both patients and family members with the disease. OBJECTIVE To describe Explanatory Models (EM) offered to caregivers of paediatric patients with conversion disorder who attended the Hospital de la Misericordia. METHODS A qualitative study was conducted with a convenience sample of 10 patients who attended the Hospital de La Misericordia, ¿Bogota? between May 2014 and April 2015. The tool used was an in-depth interview applied to parents and/or caregivers. RESULTS Caregivers have different beliefs about the origin of the symptoms, especially considering sickness, magical-mystical factors, and psychosocial factors. The symptoms are explained in each case in various ways and there is no direct relationship between these beliefs, the pattern of symptoms, and help-seeking behaviours. Symptomatic presentation is polymorphous and mainly interferes in the patient's school activities. The medical care is perceived as relevant, and psychiatric care as insufficient. Among the therapeutic routes, consultations with various agents are described, including medical care, alternative medicine, and magical-religious approaches. CONCLUSIONS EMs in conversion disorder are varied, but often include magical-religious elements and psychosocial factors. The underlying beliefs are not directly related to help-seeking behaviours or other variables.

Abstract
Dissociative (conversion) disorder (DCR) has a long and controversial history. Some authors wish to classify it with somatoform disorders separate from dissociative disorders; many researchers keep it with DCR. Symptoms pattern also varies in different cultures. This study used the criteria of International Classification of Diseases Tenth Edition (ICD-10). Study was aimed to see the presenting symptom profile of dissociative (conversion) disorder more focusing on psychotic symptoms in tertiary care hospital in Bangladesh. This cross sectional observation was carried out in two different tertiary care hospitals in Dhaka city with preformed pretested questionnaire. Data were collected from 100 consecutive patients from July 2005 to June 2006 and data were analyzed by Statistical Package of Social Science (SPSS) 16.0. Pattern of dissociative (conversion) disorder indicated that symptoms presentations are different in Bangladesh which is difficult to categorize using existing criteria of ICD-10. Among 100 consecutive patients diagnosed as dissociative (conversion) disorder 13 patients had psychotic symptoms. Psychotic presentation of conversion disorder often creates doubts among the clinicians. Careful history taking, identifying the underlying psychosocial stressors will help clinicians to diagnose them accurately. It should be noted that the pattern of presentation in South Asia may be different due to role of culture on symptoms presentation in this region.

Abstract
PURPOSE OF REVIEW This paper examines the overlap of conversion disorder with chronic pain conditions, describes ways to assess for conversion disorder, and provides an overview of evidence-based treatments for conversion disorder and chronic pain, with a focus on conversion symptoms. RECENT FINDINGS Conversion disorder is a significant problem that warrants further study, given that there are not many well-established guidelines. Accurate and timely assessment should help move treatment in a more fruitful direction and avoid unnecessary medical interventions. Advances in neuroimaging may also help further our understanding of conversion disorder. Creating a supportive environment and a collaborative treatment relationship and improving understanding of conversion symptoms appear to help individuals diagnosed with conversion disorder engage in appropriate treatments. Novel uses of earlier treatments, such as hypnosis and psychodynamic approaches, could potentially be beneficial and require a more vigorous and systematic study. There are treatments that produce significant improvements in functioning and reduction of physical symptoms from conversion disorder even for very severe cases. Hypnotherapy, cognitive behavioral therapy, and inpatient multidisciplinary treatment with intensive physiotherapy for severe cases have the most evidence to support reduction of symptoms. Components of treatment for conversion disorder overlap with treatments for chronic pain and can be used together to produce therapeutic effects for both conditions. Treatment needs to be tailored for each individual's specific symptoms.

Abstract
Functional movement disorders include motor dysfunctions which are not explained by relevant neurological examination. The prevalence of the disorders is relatively high (10-15%) within an ordinary neurological patient group. Untreated, prognosis for the conditions is poor, and neurological imaging has not yet provided explanatory hypotheses. Treatment studies are sparse, but a heterogenous group of studies of intense, multidisciplinary treatment programmes all point toward good and promising treatment effects. This is not reflected in the actual treatment capacity in Denmark.

Abstract
Functional neurological symptom disorder (FNSD) is characterized by motor or sensory impairments inconsistent with recognized neurologic conditions. Usually emerging in adolescence, somatic symptoms remain challenging for the physician to assess and treat. Also termed "conversion disorder," FNSD has been recently reconceptualized with greater diagnostic emphasis on positive neurologic findings while eliminating the requirement for a precipitating stressor. This has broadened the initial treatment emphasis from mandating psychotherapeutic engagement to a more collaborative model that requires open communication of neurologic findings and strives to align with families' perspectives. Severe disorders necessitate a unified treatment approach from several clinical specialties, including behavioral approaches, and pediatricians may play a central role in the management of youth with FNSD as well as their families. Treatment engagement can be facilitated by validating the distress of the patient, providing resources to address diagnostic questions and parental concerns, and implementing shared goals toward rapid return to self-efficacy.

Abstract
Objectives: We describe a cohort of patients with an unusual presentation of stridor, their evaluation and management, and their outcome. We review the pertinent English-language literature. Methods: We performed a retrospective review of the records of 12 adolescent patients treated for acute-onset inspiratory stridor at the Departments of Otolaryngology-Head and Neck Surgery and Allergy and Immunology at the University of South Florida and the Department of Speech Pathology at the H. Lee Moffitt Cancer Center and Research Institute. Two additional patients received treatment elsewhere. Demographic, historical, and laboratory data, physical examination findings, and follow-up information were extracted. A review of both the Hillsborough County Department of Health epidemiological report and the English-language literature was performed. Results: Fourteen female patients who attended a local high school developed audible inspiratory noise. Twelve of the 14 were seen at the University of South Florida Ear, Nose and Throat Center. The remaining 2 patients were evaluated by outside otolaryngologists but were included in all reports from the Department of Health. Environmental studies did not find noxious chemical or biological agents in the students' environments to explain the development of the symptoms. Physical and videostroboscopic examination identified two distinct laryngeal findings causing the audible stridor. One involved paradoxical vocal fold movement, and the other, supraglottic mucosal collapse into the airway. All patients underwent rigorous speech pathology intervention and structured treatment with either complete resolution or significant improvement, seen both clinically and on videostroboscopic evaluation. Conclusions: Audible stridor can arise from numerous disease processes. In the vast majority of presentations it occurs sporadically and on an individual basis. Our cohort is especially unusual because of the sheer number of patients. Our presentation of a case of mass psychogenic illness as the cause of vocal cord dysfunction with additional findings of laryngomalacia within a group of adolescent girls is the first in the English-language literature. The key to the diagnosis is recognition of the disorder and susceptible individuals by using a thorough physical examination with emphasis on the laryngoscopic and videostroboscopic findings. The systematic approach, undertaken by a team including an otolaryngologist, an allergist, a speech pathologist, and an epidemiologist, proved to be effective in the management of this complex disorder and highly unusual situation.

Abstract
Suggestion in hypnosis has been applied to the treatment of functional neurologic symptoms since the earliest descriptions of hypnosis in the 19th century. Suggestion in this sense refers to an intentional communication of beliefs or ideas, whether verbally or nonverbally, to produce subjectively convincing changes in experience and behavior. The recognition of suggestion as a psychologic process with therapeutic applications was closely linked to the derivation of hypnosis from earlier healing practices. Animal magnetism, the immediate precursor of hypnosis, arrived at a psychologic concept of suggestion along with other ideas and practices which were then incorporated into hypnosis. Before then, other forms of magnetism and ritual healing practices such as exorcism involved unintentionally suggestive verbal and nonverbal stimuli. We consider the derivation of hypnosis from these practices not only to illustrate the range of suggestive processes, but also the consistency with which suggestion has been applied to the production and removal of dissociative and functional neurologic symptoms over many centuries. Nineteenth-century practitioners treated functional symptoms with induction of hypnosis per se; imperative suggestions, or commands for specific effects; "medical clairvoyance" in hypnotic trance, in which patients diagnosed their own condition and predicted the time and manner of their recovery; and suggestion without prior hypnosis, known as "fascination" or "psychotherapeutics." Modern treatments largely involve different types of imperative suggestion with or without hypnosis. However, the therapeutic application of suggestion in hypnosis to functional and other symptoms waned in the first half of the 20th century under the separate pressures of behaviorism and psychoanalysis. In recent decades suggestion in hypnosis has been more widely applied to treating functional neurologic symptoms. Suggestion is typically applied within the context of other treatment approaches, such as cognitive-behavioral, rehabilitative, or psychodynamic therapy. Suggestions are generally symptom-focused (designed to resolve a symptom) or exploratory (using methods such as revivification or age regression to explore experiences associated with symptom onset). The evidence base is dominated by case studies and series, with a paucity of randomized controlled trials. Future evaluation studies should allow for the fact that suggestion with or without hypnosis is a component of broader treatment interventions adapted to a wide range of symptoms and presentations. An important role of the concept of suggestion in the management of functional neurologic symptoms is to raise awareness of how interactions with clinicians and wider clinical contexts can alter expectancies and beliefs of patients in ways that influence the onset, course, and remission of symptoms.

Abstract
Patients with functional neurologic disorders present to clinicians with a variety of symptomatic manifestations, with various levels of severity, chronicity, and comorbidity, as well as with various degrees of past adversity, intrinsic resilience, and available external support. Clearly, treatment must be individualized. For those patients who have been severely or chronically impaired, especially if adequate prior outpatient treatments have failed, inpatient treatment that integrates the various modalities outlined here provides a rational route of rescue from a course otherwise potentially characterized by protracted dependence and disability. Based on the data currently available, we believe this treatment approach is worthy of further study to refine the component treatment strategies and enhance the potentially most effective ingredients. For patients with severe levels of disability, who could be managed in a multimodal day-treatment program, that approach also warrants further consideration.

Abstract
Functional neurologic disorder (FND), also known as conversion disorder, is common and often associated with a poor prognosis. It has been relatively neglected by research and as such there is a conspicuous lack of evidence-based treatments. Physical and psychologic therapies are the main treatment modalities, over and above reassurance and sensitive explanation of the diagnosis. However there are two other historic treatments that have seen a recent resurgence of interest and use. The first is electric stimulation, which was initially pioneered with direct stimulation of nerves but now used indirectly (and therefore noninvasively) in the form of transcranial magnetic stimulation (TMS). The second is (therapeutic) sedation, previously known as "abreaction," where it was mostly used in the context of psychologic investigation and treatment, but now increasingly advocated during rehabilitation as a way to therapeutically demonstrate reversibility of symptoms. This chapter introduces the background of these treatment modalities, their evolution into their current applications before critically evaluating their current evidence base and exploring possible mechanisms of action. It also tentatively suggests when they should be considered in current practice and briefly considers their future potential. In summary there is encouraging preliminary evidence to suggest that both TMS and sedation may be effective treatments for FNDs.

Abstract
BACKGROUND Conversion disorder is diagnosed late, by exclusion and with a high risk of complications. There is a wide experience in adults that is not extrapolated to paediatric patients. According to the literature, the prognosis is better in children, but this changes when other variables such are included, such as comorbidities, late diagnosis and a very convincing social image of the neurological disease. OBJECTIVE To review the medical literature on the clinical features, diagnosis, comorbidities and treatment of this disorder. METHODS A literature research was performed on Medline and Pubmed, the terms used were "conversion disorder", pseudoseizures, treatment, clinic, children ("conversion disorder" OR hysteria OR hysterical) (child OR children OR childhood OR pediatric OR paediatric). The most relevant material found is included in this review. CONCLUSIONS Conversion disorder is often an imprecise diagnosis in high complexity paediatric services. No consensus was found in the literature search on how to treat patients after the initial diagnosis. The evidence that it becomes chronic is not strong enough, just as the evidence is not convincing enough to argue that comorbidity factors are those maintained over time. Clearly, there is no medical experience of the natural history of this disorder in children and adolescents. It is only known is that it is a complex condition, on which there is experience only in the diagnosis and treatment of the acute state, but not so in the long-term care. It is proposed that each patient is studied in detail in order to define the psychiatric diagnosis and its treatment.

Abstract
BACKGROUND Conversion (dissociative) disorder is a psychiatric disorder in which somatic symptoms or deficits are present in the absence of a definable organic cause. The etiology of this disorder is not yet fully understood. The most characteristic presentations are: pseudosensory syndromes, pseudoseizures, psychogenic movement disorders and pseudoparalysis. Psychogenic speech disorder is a rare form of conversion (dissociative) disorder. The aim of present case study is to complete the knowledge on this subject. SUBJECT AND METHODS The article presents a case of a fifty year old woman who developed psychogenic disorder of speech after being degraded to a lower position at work. After excluding organic background of observed symptoms, the diagnosis of conversion (dissociative) disorder was stated and adequate therapy was implemented, within the capabilities of the Ward. RESULTS Partial remission of presented symptoms was achieved as a result of psychopharmacotherapy and psychotherapy. CONCLUSIONS Before stating the diagnosis of conversion (dissociative) disorder, possible somatic causes of the observed symptoms should be excluded. Special attention should be drawn to the importance of studying the psychological and family context of this case and the patient's difficulty to understand and accept that produced symptoms might be triggered by a psychogenic factor.

Abstract
Dysphagia is a symptom shared by many medical and psychiatric conditions. A thorough Psychiatric evaluation could rule in a functional or psychological etiology. If a Psychological etiology is identified, a psychodynamic formulation could help the consultation psychiatrist clarify the origin of the symptom and provide a better explanation to the patient and medical team, resulting in improved care by prevention of unnecessary medical interventions, improvement of symptoms and individualization of the treatment.

Abstract
Conversion disorder, the development of symptoms of neurological disease with no organic basis, is a challenge for mental health professionals to diagnose and treat effectively. There are well-established predisposing factors, such as female sex, childhood trauma, and alexithymia, but less clear is how to approach the subjective suffering that is symbolized with the symptom rather than consciously recognized. While there are overlapping comorbidities such as depression and anxiety that may be treated with medication, psychotherapy is the primary effective treatment for patients with adequate capacity to engage in the process. This article addresses means of identifying patients who might benefit from psychotherapy (along with medication in some instances) as well as some guidelines for conducting psychotherapy, with case examples.

Abstract
A 10-year-old child presented with a limp for 9 months. The child was keeping his right knee extended and foot in the equinus position. The child had been investigated by numerous laboratory investigations and imaging procedures during the initial 9 months, but no organic cause was found. Without any conclusive diagnosis, the child was being managed by physical therapy. During examination in our clinic, the variable contraction of the quadriceps muscle raised the possibility of a psychiatric disorder. A psychiatrist's opinion was sought and the child was found to have dissociative motor disorder. His conflict was identified and treated by cognitive behavioral therapy. The child walked normally after 1 week. A psychogenic limp is often not suspected by the orthopedic surgeon in the evaluation of a limp. The involvement of a psychiatrist in this evaluation may be helpful to identify the condition easily and even at the first instance.

Abstract
'Hysteria' (conversion disorder) remains in modern humanity and across cultures, as it has for millennia. Advances today in tools and criteria have afforded more accurate diagnosis, and advances in treatments have empowered patients and providers, resulting in a renewed interest in somatoform disorders. Future progress in understanding mechanisms may be influenced by developments in functional neuroimaging and neurophysiology. No animal model exists for somatoform symptoms or conversion disorder. Despite the absence of a known molecular mechanism, psychotherapy is helping patients with conversion disorder to take control of their symptoms and have improved quality of life, shedding light on what was once an enigma.

Abstract
The symptoms of conversion disorder are not due to conscious simulation. There should be no doubt that the symptoms of conversion disorder are genuine, even if scans do not reveal any abnormalities. The management of patients with conversion disorder starts with an explanation of the diagnosis. The essence of this explanation is that patients first hear about what the diagnosis actually means and only after this about what they do not have. When explaining the diagnosis it is a good idea to use metaphors. The treatment of patients with conversion disorder is carried out together with a physical therapist. The collaboration of healthcare professionals who are involved in the treatment of a patient with conversion disorder should preferably be coordinated by the patient's general practitioner.

Abstract
Globus hystericus (GH) is a subjective feeling of a lump or foreign body in the throat thought to involve psychogenic factors, a form of somatisation disorder. The more modern terms, globus sensation or globus pharyngeus, reflect recognition of one or more possible contributing anatomico-physiological factors, such as gastro-oesophageal reflux disease (GORD) or pharyngeal inflammation.

Abstract
The aim of the present paper has been to explore the medieval evidence on miraculous healings of paralysis and to confront it with modern medical knowledge. Paralysis has been selected as a model for such a study and St. Bernardino of Siena (1380-1444) as a model of a saintly healer. Analyzed were the primary sources and modern literature. Paralysis was found to be among the most frequent diseases in medieval miracle reports, including the healings by St. Bernardino. According to the hypothesis offered in the paper, the majority of medieval cases of "miraculously healed paralysis" was of conversive origin.

Abstract
Psychogenic nonepileptic seizures (PNES) are clinical events resembling epileptic seizures but lacking abnormal cortical electrical discharges. They are involuntary manifestations of a psychological distress. PNES are less frequent in the pediatric population than in adults, they represent from 3.5 to 9% of patients admitted for prolonged video-EEG (PV-EEG). Diagnosis is rarely made on history only and PV-EEG is mandatory to obtain a definitive diagnosis. Children as young as 5 years can present with PNES. They are more frequent in girls except in school age children where boys are identically or more represented than girls. PNES can either present with subtle signs, even unresponsiveness, or prominent motor activity. Major differential diagnosis is absences, day dreaming, and complex partial seizures including hyperkinetic frontal seizures. PNES are usually rapidly registered during PV-EEG and provocative methods have not been thoroughly studied in children. Major risk factors are psychological stressors, such as school or family problems. Psychiatric conditions are less frequent than in adults though they should be looked for. Prognosis is better than in adults, and most children become PNES-free. There are no guidelines for treatment, however stressors should be addressed. In general, it should be clearly explained that PNES are not epileptic seizures.

Abstract
"Hysterical" conversion hasn't vanished, and remains a diagnostic, therapeutic and relational challenge for the clinician. Conversion may be associated with organic disease. From the clinical point of view, two subtypes of conversion symptoms, namely psychogenic nonepileptic seizures and functional movement disorders, have been individualized. Physical signs of neurological inconsistency, and classical arguments in favor of a psychological etiology have been recently reevaluated, which allows, along with the progress of neurological investigations, to minimize the rate of misdiagnosis. Functional neuroimaging has shed light on the brain mechanisms involved in conversion phenomena. From a nosological point of view, there is a tension between the whish to "banalize" the conversion symptoms as mere "functional neurological symptoms", which makes easier to communicate the diagnosis to the patient and may remove the stigma from the diagnosis; and the wish of certain authors to "revive" hysteria, emphasizing the core phenomenon of dissociation and its close relationship with trauma. Proposed treatment of conversion disorder are numerous, although poorly evaluated and often insatisfactory, but recent publications insist on the importance of communicating the diagnosis to the patient in a honest, nonjudmental and understandable way, at the earliest phase of the disorder.

Abstract
Conversion disorder (CD) in children remains a major challenge both in pediatric and mental health clinics and is still a prevalent psychiatric disorder in developing countries. The authors describe a 10-year-old boy with the complaints of inability to walk, speak or eat, excessive drooling, urinary and fecal incontinence, disturbance from light and sound, and expression of needs only by eye movements. The patient diagnosed with CD was followed by the Department of Child and Adolescent Psychiatry with play therapy, individual psychotherapy and family therapy. At the end of three months, the patient was discharged. This is one of the most challenging cases of CD in children. The most important aim of the treatment is to understand the need for conversion symptoms and to constitute a healthy psychological environment for the child rather than to remove the physical symptoms.

Abstract
This report describes the rare case of a 27-year-old female patient with conversion disorder who presented unilateral ptosis with ipsilateral muscle spasm of orbicular oculi. The co-existing of ptosis and muscle spasm of orbicular oculi indicates that, in accord with prior reports, the overactivity of orbicular oculi is essential in psychogenic pseudoptosis. The co-existing of unilateral ptosis and ipsilateral muscle spasm of orbicular oculi in the present case leads us to the conclusion that the overactivity of orbicular oculi is essential in psychogenic pseudoptosis.

Abstract
Conversion disorder or functional neurological disorder is a neurological symptom complex originating from psychological factors, which manifests in voluntary motor and sensory functions or as unexplained epilepsy-like seizures. Until the 1980's the disorder was called hysterical neurosis. Later on, various general terms, such as unexplained somatic symptoms, pseudoneurological, somatoformic, psychogenic, or psychosomatic symptoms, have been applied. The latest phrase, functional neurological symptoms, emphasizes the change in the functioning of the nervous system rather than in its structure.

Abstract
Treatment for PNES must be individualized. A combination of approaches is probably the most beneficial for improvement. Treatment should not simply emphasize removing maladaptive PNES behaviour, but should also focus on learning new coping skills and removing secondary gains. If PNES persist, therapy should be re-evaluated.

Abstract
AIMS Our study aims to make inferences from inpatient admission of conversion disorder with regards it's age and sex distribution, clinical presentation, yearly distribution of admission and morbidity of conversion disorder in comparison to total psychiatric admissions. It also compares it's results with those of previous studies in this country, neighbouring countries and western studies. METHODS A case notes review was done for admissions of this disorder for five years in Mosul University Hospital. The data were inputted into SPSS programme and analysed. The statistical analysis was by t-test, Anova and regression. RESULTS Two hundred seventy five patients were admitted during the period; 224 women and 51 men. The majority of men came from Urban areas compared to 58% of women. Single status was over represented; 59% compared to 34% married. Women formed 82% of the singles, 90% of the widows and 83% of the divorced. Pseudo-fits was the most frequent diagnosis. There was no significant change in the number of yearly admissions apart from the first year. The proportion of conversion disorders compared to total psychiatric disorders admissions was 7.4%. IMPLICATIONS Results were consistent with national studies but showed higher figures than neighbouring countries. What was interesting was that, results were consistent with figures in United Kingdom before 1950.

Abstract
Intractable sneezing is not a commonly encountered disorder. The clinical presentation of such patients may cause the physician to undertake several tests before making a diagnosis. Are the performed analytic tests a waste of the health service funds or are they really sufficient? In this case, after undergoing several tests to rule out potential causes of the prevailing symptoms, psychiatric evaluation revealed a triggering event that contributed to the diagnosis of psychogenic sneezing. This specific case demonstrates why the diagnosis of psychogenic sneezing is difficult. An overwhelming number of such patients may be linked to a psychogenic cause; nevertheless, organic lesions or causes should be carefully excluded. Addressing the psychosocial issues through psychotherapy and coincidental use of locally administered anesthesia assisted in resolving the symptoms.
