Characteristics and Outcomes of Children With Conversion Disorder Admitted to a Single Inpatient Rehabilitation Unit, A Retrospective Study

Characteristics and outcomes of youth with functional seizures attending intensive interdisciplinary pain treatment

Functional seizures (FS) can be debilitating and negatively impact quality of life. Yet intervention research for FS is limited, especially for youth. This study examined clinical characteristics and outcomes of youth with FS (13-23 years) presenting to a pediatric intensive interdisciplinary pain treatment (IIPT) program in the midwestern United States. Sixty youth (mean age = 16.5 years; 83.3 % female) met inclusion criteria. At intake, comorbid chronic pain, somatic symptoms, autonomic dysfunction, eating and weight disturbances, and mental health concerns were common. Despite this high symptom burden, youth with FS reported significant improvements in functioning measured with the Functional Disability Inventory, t(53) = 9.80, p <.001, d = 1.32; depression measured with the Center for Epidemiological Studies - Depression Scale for Children, t(53) = 6.76, p <.001, d = 0.91; anxiety measured with the Spence Children's Anxiety Scale, t(53) = 3.97, p < .001, d = 0.53; and catastrophizing measured with the Pain Catastrophizing Scale for Children, t(53) = 6.44, p <.001, d = 0.86, following completion of the program, suggesting that IIPT may be an effective treatment option for highly disabled and emotionally distressed youth with FS. Future research is needed to continue to refine best practices for youth with FS to reduce suffering and improve outcomes.

[Conversion disorder, caring for body, mind]

Conversion disorder is a psychiatric disorder whose clinic and management lie at the crossroads between body and mind. It challenges healthcare professionals in terms of diagnosis, further investigation, referral and care. A number of questions arise, such as how caregivers perceive the relationship between body and mind, the place of the psychiatric hypothesis among the initial diagnostic hypotheses, and the temporality of care.

Evidence-Based Mind-Body Interventions for Children and Adolescents with Functional Neurological Disorder

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.

Sense of control, selective attention and cognitive inhibition in pediatric functional seizures: A prospective case-control study

PURPOSE

To date, laboratory-based experimental behavioral methods have not been used to identify factors associated with pediatric functional seizures (FS), leaving a critical gap for effective treatment development.

METHODS

Children ages 13-18 with video-EEG-confirmed FS were matched to controls (MCs) based on income, sex, race, and age. A modified Stroop task which included a condition requiring participants to report the ink colors in which seizure symptom words were written (e.g., "shaking" in blue) measured selective attention and cognitive inhibition through response time. The magic and turbulence task assessed sense of control in three conditions (magic, lag, turbulence). Children with FS were asked to report premonitory symptoms predicting FS.

RESULTS

Participants included 26 children with FS and 26 MCs (Meanage=15.2, 74% female, 59% white). On Stroop, children with FS had a slower reaction time (Mean=1193.83) than MCs (Mean=949.26, p = 0.022) for seizure symptom words. Children with FS had significantly poorer sense of control in the turbulence condition of the magic and turbulence task (Mean=-3.99, SD=8.83) than MCs (Mean=-11.51, SD=7.87; t(20)=-2.61, p =0.017). Children with FS (Mean=-1.80, SD=6.54) also had significantly poorer sense of control in the magic condition than MCs (Mean=-5.57, SD=6.01; p =0.028). Ninety-eight percent of patients endorsed premonitory symptoms.

CONCLUSION

Compared with MCs, children with FS have (1) poorer selective attention and cognitive inhibition when presented with seizure-related information and (2) lower sense of control (i.e. poorer awareness that their control was manipulated). Premonitory symptoms were common. Sense of control, selective attention, and inhibition may be novel treatment targets for FS intervention.

The Role of Physiotherapy in the Management of Functional Neurological Disorder in Children and Adolescents

Children and adolescents with functional neurological (conversion) disorder (FND) present with symptoms of impaired motor and sensory function. FND involves complex interactions between the brain, mind, body, and lived experience of the child. The gold standard for treatment is therefore a holistic, biopsychosocial approach with multimodal interventions delivered by a multidisciplinary team. In this narrative review we examine the role of physiotherapy in managing FND in children. We searched Embase, Medline, PsycINFO, and PubMed (back to 2000) for relevant physiotherapy articles and also manually searched their reference lists. Two review articles and ten observational studies were identified. Data were extracted concerning the type of study, therapies involved, outcome measures, and comorbid mental health outcomes. FND symptoms resolved in 85% to 95% of the patients, and about two-thirds returned to full-time school after completing the multidisciplinary intervention. Ongoing mental health concerns at follow-up were associated with poorer functional outcomes. Key themes included the following: use of psychological interventions embedded in the physiotherapy intervention; integration of play, music, and dance; role of physical exercise in modulating physiological, neural, and endocrine systems; need for FND-specific outcome measures; ethical issues pertaining to randomized trials; and need to develop alternate study methodologies for assessing combined treatments. Clinical vignettes were included to highlight a range of physiotherapy interventions. In conclusion, the emerging literature suggests that physiotherapy for children with FND is a useful intervention for improving motor dysfunction and for addressing other concurrent issues such as physical deconditioning, neuroprotection, chronic pain, disturbed sleep, anxiety and depression, and resilience building.

Sensory Processing Difficulties in Patients with Functional Neurological Disorder: Occupational Therapy Management Strategies and Two Cases

Functional neurological disorder (FND) is a condition at the intersection of neurology and psychiatry, with some patients experiencing sensory hypersensitivities and other sensory processing difficulties. It has been postulated that poor integration and modulation of sensory information with cognitive, affective and behavioral processes may play a role in the pathophysiology of FND. In this article, we first succinctly review the role for occupational therapy (OT) in the multidisciplinary therapeutic approach to managing patients with FND. After highlighting previously published data identifying sensory processing difficulties in patients with FND, we subsequently outline the components of the sensory-based outpatient OT program for FND at the Massachusetts General Hospital. Here, we detail how occupational therapists assess and treat sensory modulation difficulties with the aid of resources like the Adolescent/Adult Sensory Profile (AASP), The Canadian Occupational Performance Measure (COPM), and the Sensory-Motor Preference Checklist. We then report on 2 clinical cases representative of the sensory modulation difficulties endorsed by some patients with FND, illustrating how developing an individualized, sensory-based treatment plan can help improve functional neurological symptoms and overall participation in activities of daily living. Prospective, controlled research is needed to further operationalize OT-based sensory modulation interventions, as well as define the tolerability and efficacy of this intervention for pediatric and adult populations with FND.

Treatment of Pediatric Functional Neurological Symptom Disorder: A Review of the State of the Literature

Functional Neurological Symptom Disorder (FNSD), or experiencing neurological symptoms incompatible with either a neurological condition or a medical condition, is a common condition presenting in children and adolescents. It is associated with impairment in quality of life for patients and their families and represents a significant burden to the healthcare system. There is currently limited research available regarding effective treatment of pediatric FNSD. Currently, only one RCT exists studying effective treatment of FNSD in children and adolescents, and it is limited to one sub-type of FNSD and only examined cognitive behavioral therapy compared to supportive therapy. Despite this, almost all published research supports good prognosis for pediatric FNSD with all studies reporting improvement either in FNSD symptoms or in the quality of life and functioning of patients with FNSD. The most support was found for the use of cognitive behavioral therapy either as a stand-alone treatment or in the context of interdisciplinary treatment. Future research should focus on increasing the rigor of research, including expanding RCTs to include additional sub-types of FNSD and comparing across various treatment modalities.

Treatment Approaches for Functional Neurological Disorders in Children

Purpose of Review

Functional neurological disorder (FND) is a multi-network brain disorder that encompasses a broad range of neurological symptoms. FND is common in pediatric practice. It places substantial strains on children, families, and health care systems. Treatment begins at assessment, which requires the following: the medical task of making the diagnosis, the interpersonal task of engaging the child and family so that they feel heard and respected, the communication task of communicating and explaining the diagnosis, and the logistical task of organizing treatment.

Recent Findings

Over the past decade, three treatment approaches—Retraining and Control Therapy (ReACT), other cognitive-behavioral therapies, and multidisciplinary rehabilitation—have been evaluated in the USA, Canada, and Australia. Of children treated in such programs, 63 − 95% showed full resolution of FND symptoms. The common thread across the programs is their biopsychosocial approach—consideration of biological, psychological, relational, and school-related factors that contribute to the child’s clinical presentation.

Summary

Current research strongly supports a biopsychosocial approach to pediatric FND and provides a foundation for a stepped approach to treatment. Stepped care is initially tailored to the needs of the individual child (and family) based on the pattern and severity of FND presentation. The level of care and type of intervention may then be adjusted to consider the child’s response, over time, to treatment or treatment combinations. Future research is needed to confirm effective treatment targets, to inform the development of stepped care, and to improve methodologies that can assess the efficacy of stepped-care interventions.

Neuropsychiatric Treatment Approaches for Functional Neurological Disorder: A How to Guide

There is a growing body of knowledge regarding management of functional neurological disorder (FND). The aim of this article is to guide the clinician through FND clinical management, from delivery of the diagnosis, to creation of a biopsychosocially-informed treatment plan, to troubleshooting common issues that arise throughout longitudinal care. We review the evidence and core principles of both rehabilitative therapies (physical therapy, occupational therapy, and speech and language therapy) and psychological therapies for the treatment of FND, and discuss the benefits of engaging a multidisciplinary and interdisciplinary team. The optimal timing of specific therapeutic interventions is also discussed, emphasizing a patient-centered perspective. Resources for further reading, for both patients and clinicians, are provided throughout. Additional research is needed to further optimize the therapeutic approach to patients with FND, including the need to develop novel treatments for those that do not positively respond to currently available interventions.

Functional neurological symptom disorder: Preliminary findings of factors associated with walking ability post integrative pediatric rehabilitation

PURPOSE

The current study's aims were to (1) examine long-distance walking ability (6-minute walking test [6MWT]) and walking hemodynamic responses (i.e., heart rate) among youth with functional neurological symptom disorder (FNSD) before and after an integrative pediatric rehabilitation (IPR) program; and (2) explore factors predicting improvement in walking ability.

METHODS

Thirty-one youth with FNSD participating in an IPR program were recruited. The IPR program was activated biweekly in an ambulatory format. Study measures included the 6MWT, hemodynamic characteristics, rate of perceived exertion (RPE), pain-intensity perception, and Child's Somatization Inventory-24 (CSI-24). All measures were conducted upon admission to the IPR and discharge.

RESULTS

Findings indicated a significant increase in 6MWT distance, as well as decreases in heart rate, RPE, and pain-intensity perception from admission to discharge. At admission, CSI-24 and pain intensity predicted 6MWT distance (adjusted R2 = 0.68). Pain intensity predicted discharge 6MWT distance (adjusted R2 = 0.18). Initial 6MWT predicted changes in 6MWT distance from admission to discharge (adjusted R2 = 0.33).

CONCLUSION

Using an integrative rehabilitation approach increases walking distance and decreases pain-related symptoms in youth with FNSD, emphasizing the need for collaboration between physical therapists and pediatric psychologists. Moreover, changes in walking ability may increase participation and thus should be the focus of IPR.

One-year follow-up of treatment outcomes and patient opinions of Retraining and Control Therapy (ReACT) for pediatric functional seizures

Retraining and Control Therapy (ReACT), a short-term treatment for pediatric functional seizures (FS), has been demonstrated to improve FS in children compared to supportive therapy. However, long-term maintenance of FS-reduction after ReACT is unclear. This study aims to assess seizure frequency 1 year after ReACT and determine patient and parents' opinions of ReACT. Children with functional seizures who previously completed ReACT and their parents were asked to report 30-day FS frequency 1 year after completing ReACT. They also reported if ReACT was helpful. Paired samples t-tests were used to compare FS frequency before ReACT to 1 year after and to compare FS frequency in 30 days after ReACT to 1 year after. Fourteen children (Mean_age = 15.43) and their parents participated. Seven-day FS frequency for patients at 1-year follow-up (Mean = 0.15) was significantly lower than 7-day FS frequency pre-ReACT (Mean = 5.62; p = 0.005). No differences were found when comparing FS frequency during 30 days post-ReACT (Mean = 0.29) and in 30 days before 1-year follow-up (Mean = 0.71). This study confirms long-term maintenance of FS-reduction after ReACT and supports the efficacy of targeting FS directly as opposed to mood or stress for reducing FS. Additionally, children and parents believe ReACT is beneficial.

["Somatic symptom disorders" in adolescence. A systematic review of the recent literature]

OBJECTIVES

Body expression of mental disorders is common in adolescence. Only two literature reviews over the last five years have been identified about somatoform disorders in children., The present article provides a systematic review of articles in English, which concern "Somatic Symptom and Related Disorders" according to the DSM-5 (Diagnostic and Statistical Manual - 5th Edition) among adolescents.

METHODS

The article search was made on Medline, Psychinfo, Google Scholar, BiomedCentral, Central and tripdatabase (for grey literature) according to PRISMA criteria and with the items "somatoform disorders" or "somatic symptom disorders". An age filter was applied for "adolescents", and a selection was done from the last five years. All articles concerning adolescents (often associated with children) were initially included, except for articles concerning eating disorders, dysmorphic disorders or adult population. Comments, editorials, opinion or descriptive articles were also excluded. The authors then carried out an analysis of the main topics, themes and questions covered in the selected publications and presented a descriptive synthesis.

RESULTS

A total of seventy-seven publications were included in the analysis, from three hundred and seventy-two publications. First, the terms used to refer to these "somatic symptom disorders" were varied, such as "somatization", "somatic complaints/symptoms", "functional disorder", "unexplained symptoms" and "somatoform disorders". Then, studies related just to adolescents were limited: most of studies included children and adolescents in their methodologies; and some of them questioned somatic symptoms from a developmental perspective. Case reports were the most represented articles among all medical specialties, with clinical descriptions about "functional neurological symptom disorder", "factitious disorder" and "somatic symptom disorder" with a medical disease, among children and adolescents. We sometimes observed a controversial borderline between psychological and somatic disorders. Various explanatory models appeared, especially the trauma path; familial and social environment was also pointed out, with a possible peer group effect; neurocognitive theories were finally described. The literature highlights the effectiveness of psychosocial therapies (especially the cognitive-behavioral therapy) and the importance of multidisciplinary management. Finally, a few studies with a qualitative methodology are represented.

CONCLUSIONS

Only nine articles included "somatic symptom disorder" in their titles, despite a terminology valued by many authors (compared to "somatoform disorders" from the DSM-IV). The heterogeneity of terminologies, case reports and explanatory models witness a lack of connexions between medical specialties. This could explain in part the wandering of adolescents and their families in the health care system. It could also contribute to the delay before diagnosis, especially when neurological symptoms exist, and a late referral for psychiatric consultation. Further studies are needed to understand difficulties to use a clinical pathway among medical specialties, when the benefit of amultidisciplinary approach seems to be unanimous.

Psychologically Informed Physical Therapy for Children and Adolescents With Functional Neurological Symptoms: The Wellness Approach

Children with functional neurological disorder (FND) present with motor and sensory neurological symptoms that impair health and physical functioning and that create an ongoing clinical burden for caregivers and hospitals worldwide. Treatment programs for these children involve a multidisciplinary approach with physical therapy as a fundamental component. However, standard musculoskeletal approaches to physical therapy are ineffective or may even exacerbate symptoms because they are unresponsive to the biopsychosocial context in which FND emerges: FND typically occurs in the context of stress, either physical or emotional; symptoms are amplified by attention; and presentations are complicated by psychological factors. Informed, in part, by published guidelines for physical therapy with adult FND patients, this article examines common challenges that arise when working with children: overcoming previous negative encounters in the medical system; avoiding amplification of symptoms by drawing attention to them; and managing comorbid pain, falls, faints, nonepileptic seizures, dizziness, fatigue, and breathlessness, plus psychological symptoms such as anticipatory anxiety and panic attacks. What emerges is a psychologically informed therapeutic approach to physical therapy for children with functional neurological symptoms. This approach prioritizes interpersonal processes and physical therapy techniques that establish a therapeutic relationship and create a safe space for physical therapy, that use indirect physical therapy approaches redirecting the focus of attention away from symptoms and emphasizing the completion of tasks and activities engaging the sick body part indirectly, that tailor the intervention to address the needs and presentation of each particular child, and that integrate psychological interventions to manage common challenges.

Somatic symptom and related disorders in a tertiary paediatric hospital: prevalence, reach and complexity

Specialist paediatric services manage a variety of presentations of functional somatic symptoms. We aimed to describe the presentation and management of children and adolescents with somatic symptom and related disorders (SSRDs) requiring admission to a tertiary children's hospital with the objective of informing the development of a local clinical pathway. Patients admitted to any hospital department from May 2016 to November 2017 were identified through an electronic medical record (EMR)-linked diagnosis of SSRD. Each record was reviewed for demographic details and admission histories. The frequency of interspecialty consultations and multidisciplinary team (MDT) family meetings were recorded. One hundred twenty-three patients with SSRD were admitted on 203 occasions to 17 different departments. The median (range) age was 14.3 (7.3-18.3) years. Interspecialty consultations occurred in 84.6% of patients, and MDT family meetings occurred in 18.9% patients. SSRD was diagnosed as an inpatient in 79.9% patients, yet only 40.7% of patients, including those with multiple admissions, had SSRD recorded as a discharge diagnosis.Conclusion: Despite high rates of consultation with hospital teams, the frequency of MDT family meetings was low, and less than half the patients had SSRD documented at discharge. This affirms the value of developing a local clinical pathway. What is Known • Functional somatic symptoms are commonly seen in children and adolescents. • Few studies have explored the reach of functional somatic symptoms across a tertiary paediatric hospital; the majority of inpatient studies have focused on a limited set of disorders or cases referred to psychiatry departments. What is New • Symptoms that spanned multiple body systems were the most common presentation of SSRDs in admitted children and adolescents. • Somatic symptom disorders are less likely to be recorded as a discharge diagnosis compared with functional neurological symptom disorder.

Psychologically informed physiotherapy as part of a multidisciplinary rehabilitation program for children and adolescents with functional neurological disorder: Physical and mental health outcomes

AIM

Children and adolescents with functional neurological disorder (FND) present with physical impairment and mental health comorbidities. Specialist physiotherapy programs for treating FND have been developed over the last two decades. This article reports outcome data from three cohorts of children treated with a multidisciplinary rehabilitation intervention - the Mind-Body Program - in which a psychologically informed physiotherapy intervention, known as the wellness approach to physiotherapy, was a key component.

METHODS

For three cohorts of children (n = 57, n = 60 and n = 25, respectively) treated in the Mind-Body Program, data about functional impairment and mental health concerns were collected at presentation and at follow-up (4 years, 12 months and 18 months, respectively).

RESULTS

Outcome data show that FND symptoms resolved in 54/57 (95%), 51/60 (85%) and 22/25 (88%) of children in the three cohorts, and that 31/57 (61%), 32/60 (53%) and 13/25 (52%) of children returned to full health and to full-time school attendance. Changes in Global Assessment of Function (GAF) were significant (t(54) = 21.60, P < 0.001; t(55) = 9.92, P < 0.001; t(24) = 6.51, P < 0.001). Outcomes were less favourable for children with chronic FND symptoms at presentation; those whose comorbid mental health disorders or other (comorbid) functional somatic symptoms did not resolve; and those who subsequently developed chronic mental health problems.

CONCLUSIONS

Implementation of a multidisciplinary rehabilitation intervention - with psychologically informed physiotherapy as one of the key treatment components - resulted in resolution of FND symptoms and return to health and well-being in the large majority of patients.

Clinical overlap of functional neurologic symptom disorder and complex regional pain syndrome in pediatrics: A case report

This case study documents a 13-year-old female who presented to our intensive inpatient chronic pain rehabilitation program with complex regional pain syndrome (CRPS) of her left leg, which was significantly interfering with her normal daily functioning. She participated in a full day of traditional interdisciplinary therapies, including physical and occupational therapy for 3 hours daily. As assistive equipment was altered or weaned her physical mobility, balance, and tremors worsened and/or increased. As she began advancing her legs more independently (versus requiring physical assist), she demonstrated more variable functional strength and stability, inconsistent balance reactions, and a more unsteady gait pattern. The team was treating her according to her incoming CRPS diagnosis; however, as treatment progressed, her physical and psychological presentation seemed more aligned with diagnostic criteria of functional neurologic symptom disorder (FND). Staff then treated according to the FND diagnosis resulting in successful long-term outcomes. The clinical impact from this case study includes highlighting the commonalities between CPRS and FND clinically, discussing treatment suggestions depending on the diagnosis, and emphasizing key components of family/patient education.

Understanding and Managing Adolescents with Conversion and Functional Disorders

A functional disorder is a constellation of bothersome physical symptoms that compromise regular function but for which there is no identifiable organic or psychiatric pathology. Functional disorders can present with various symptoms. Common forms of functional disorders include functional neurologic symptom disorder (also referred to as "conversion disorder"), functional gastrointestinal disorders, chronic pain syndromes, and chronic fatigue. One-third to one-half of outpatient consultations in many practices are due to functional disorders. Functional disorders must be distinguished from structural and psychiatric disorders but should not be considered diagnoses of exclusion. Recovery is facilitated by good relationships between patients and practitioners, with good explanations of the pathophysiology of functional disorders and effective encouragement and education of patients.

Interdisciplinarity and Integration: An Introduction to the Special Issue on Psychopathology in Medical Settings

As the world views, incredulously, the calamitous consequences of the COVID-19 pandemic, the inseparable connections between body and mind become more and more apparent, even for the heretics (i.e., biological determinists). Such realizations also bolster the understanding of the close link between medical conditions and psychopathology. Launched prior to the COVID-19 epidemic, this special issue sets out to illuminate the prevalence, course, etiology, and responses to a myriad of psychopathological conditions in medical conditions. The 13 articles in this special issue address a variety of medical conditions (chronic illness and chronic pain, Pica, cancer, acute delirium, factitious disorders, functional neurological symptoms, sleep disorders, fetal conditions), mental disorders (depression, anxiety, suicidality, eating disorders, personality disorders, PTSD), medical settings (primary care vs. specialty clinics), and developmental levels (children, adolescents, and adults). The overarching theme emanating from reading these articles is that clinical-health psychology, or clinical psychology in medical settings, is an ever-needed field of inquiry, epitomizing interdisciplinarity and science/practice integration.

Measuring functional recovery in somatic symptom and related disorders: a scoping review

OBJECTIVE

Somatic symptom and related disorders (SSRDs) are prevalent, heterogenous conditions that have the potential to profoundly affect normative function in children and adolescents. Yet there is little understanding of pathways to recovery. This study aimed to systematically scope how functional recovery has been measured in children and adolescents with SSRD .

DESIGN

Scoping review of primary studies.

METHOD

Medline (Ovid) and PsychInfo were systematically searched for publications from January 1998 to April 2019. Primary studies in English that reported functional outcomes of children and adolescents with SSRD were included. Case reports and population studies were excluded. Within the tools and clinician notes, the core domains of functional outcome were identified.

RESULTS

Sixteen studies were identified that used 11 different functional outcome tools. The domains assessed within these functional outcome tools, together with the domains noted by clinicians, included physical and mental health symptoms, as well as school attendance and academic outcomes, recreational participation, impact on family and service utilisation. There was no evidence of a preferred outcome measure as only two of the tools were used in more than one study.

CONCLUSIONS

The variability of tools and domains used to measure functional recovery in children and adolescents with SSRD suggests lack of conceptual agreement about what constitutes functional recovery. Continued focus on symptom measurement or mental health comorbidities risks limiting research to single types of disorder (eg, functional neurological disability) or interventions, which threatens a much needed wider research agenda around appropriate treatment, including of complex and persistent disorders.

Retraining and control therapy for pediatric psychogenic non-epileptic seizures

Objective

Our aim was to conduct a pilot randomized controlled trial of a novel cognitive behaviorally based intervention for pediatric PNES called Retraining and Control Therapy (ReACT).

Methods

Participants were randomized to receive either eight sessions of ReACT or supportive therapy, and participants completed follow‐up visits at 7‐ and 60‐days posttreatment. The primary outcome measure was PNES frequency at 7‐days posttreatment. Eligibility criteria included children with video‐EEG confirmed PNES and participant/parent or guardian willingness to participate in treatment. Exclusion criteria included substance use, psychosis, and severe intellectual disability. Forty‐two patients were assessed for eligibility and 32 were randomized. ReACT aimed to retrain classically conditioned, involuntary PNES by targeting catastrophic symptom expectations and a low sense of control over symptoms using principles of habit reversal. Supportive therapy was based on the assumption that relief from stress or problems can be achieved by discussion with a therapist.

Results

Twenty‐nine participants (M_age = 15.1 years, SD_age = 2.5; 72.2% female; 57.1% Caucasian, 28.6% African American) completed 7‐days postprocedures. For PNES frequency, the Wilcoxon Rank Sum test statistic was 273.5 yielding a normal approximation of Z = 4.725 (P < 0.0001), indicating a significant improvement in PNES frequency for ReACT at 7‐days posttreatment compared to supportive therapy. Participants with PNES in the 7‐days posttreatment were removed from the study for additional treatment, resulting in no 60‐day follow‐up data for supportive therapy.

Interpretation

ReACT resulted in significantly greater PNES reduction than supportive therapy, with 100% of patients experiencing no PNES in 7 days after ReACT. Additionally, 82% remained PNES‐free for 60 days after ReACT.
