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

Telehealth provision of Retraining and Control Therapy (ReACT) on cognitive and biopsychosocial functioning in pediatric functional neurological disorder

INTRODUCTION

Retraining and Control Therapy (ReACT) has been shown to improve functional seizure (FS) frequency. This prospective observational study evaluated the effects of ReACT on mixed functional neurological disorder (FND) symptoms and the maintenance of outcomes 6-months post-treatment. We hypothesized that all mixed FND symptoms and other biopsychosocial outcomes would improve following ReACT.

METHODS

Adolescents ages 11-18 with FS completed one in-person and 11 telehealth ReACT sessions. Participants self-reported FS frequency for 30-days pre-treatment, 30-days post-treatment, and 30-days at 6-months post-treatment. Cognitive performance was assessed at baseline and 1-week post-treatment. Other biopsychosocial assessments and FND symptoms were self-reported at baseline, 1-week post-treatment, and 6-months post-treatment. Descriptive statistics assessed changes in FND symptoms. Paired-samples t-tests and ANOVAs assessed changes in cognitive and biopsychosocial outcomes.

RESULTS

The final sample included 34 consecutively enrolled adolescents (82.4 % Female sex; 70.6 % White; Mage = 15.4, SD = 1.9) who completed 12 sessions of ReACT and 1-week post-treatment assessments. Twenty-eight adolescents completed 6-months post-treatment assessments. At 30-days and 6-months post-treatment, 94 % and 87 % of adolescents reported ≥50 % reduction in FS, respectively, and 62 % and 61 % reported FS freedom, respectively. At 1-week post-treatment, 60 %, 60 %, and 80 % of adolescents who previously reported positive motor (excluding FS), negative motor, or psychological/cognitive FND symptoms, respectively, reported symptom freedom. By 6-months post-treatment, these percentages were 75 %, 70 %, and 100 %. Biopsychosocial outcomes improved and were maintained or continued to improve at 6-months post-treatment.

CONCLUSION

At 6-months post-ReACT, adolescents with FND experienced broad functional and biopsychosocial improvements. Telehealth provision demonstrates the potential to expand treatment access.

A Multidisciplinary Approach to Nonepileptic Events

OBJECTIVE

This article provides a guide for neurologists managing nonepileptic events (NEEs), a complex intersection of neurology and psychiatry. It covers risk factors, pathophysiology, current treatment approaches, and prognosis, with specific management strategies for challenging scenarios such as patients with intellectual disabilities and comorbid epilepsy.

LATEST DEVELOPMENTS

An emphasis on strong communication and coordinated care among health care specialists improves patient outcomes and reduces unnecessary medical consultations and procedures. This approach is now recognized as essential for addressing the complex presentation and comorbidities associated with NEEs.

ESSENTIAL POINTS

NEEs are prevalent and highly disabling, and multiple pathophysiologic mechanisms for these events have been proposed. Mortality is comparable with that of patients with treatment-refractory epilepsy, and prognosis is better for children than adults. Achievable treatment goals for adults include improved quality of life and reduced frequency and severity of events, even if complete remission of NEEs is not achieved. Enhanced communication and coordinated care through multidisciplinary care teams enable the efficient use of individual expertise at different treatment stages to address the presentation, risk factors, and comorbidities associated with NEEs, resulting in a better quality of life for patients.

Re-PROGRAM: The evaluation of a brief intervention program for patients with functional seizures in an outpatient hospital setting

OBJECTIVE

Functional seizures (FS) account for 20%-25% of referrals to specialist epilepsy clinics. They are associated with major disability, increased mortality, and frequent and costly health care use. Current guidelines emphasize the importance of implementing clinical pathways to coordinate and deliver effective treatment, but there are few targeted evidence-based interventions that reliably improve patient outcomes, and treatment resources are limited. We conducted a retrospective evaluation of Re-PROGRAM, a novel, brief intervention for functional seizure patients, to assess its feasibility in an outpatient setting.

METHODS

Twenty-nine patients with FS undertook Re-PROGRAM between August 2020 and January 2022 at the Alfred Hospital Functional Seizures Clinic, Melbourne, Australia. The intervention comprised five 60-90-min consecutive weekly appointments via telehealth, where psychologists engaged patients in a structured program of seizure management skills, lifestyle modification, and behavioral activation strategies. Following the intervention, patient feedback was collected in routine clinical follow-up as well as with a 24-item self-report pre-/postintervention comparison questionnaire.

RESULTS

All 29 patients who enrolled in Re-PROGRAM completed the scheduled sessions. Of those who returned the postintervention questionnaire (n = 16), 15 reported a reduction in seizure frequency. Four patients were lost to follow-up. Of the remaining nine, eight reported seizure frequency reduction during clinical follow-up. Qualitative analysis of the feedback revealed the majority of patients reported reduced seizure duration, intensity, and bothersomeness, and patients felt improvements in their sense of control over seizures, confidence to use seizure control strategies, assertive communication, problem solving, coping skills, relationships with others, and their day-to-day functioning.

SIGNIFICANCE

This retrospective evaluation demonstrates the feasibility and acceptability of Re-PROGRAM as a brief intervention for individuals diagnosed with FS delivered in a clinical outpatient setting and warrants further investigation in larger scale, randomized controlled studies.

Nocebo Hypothesis Cognitive Behavioural Therapy (NH-CBT) for non-epileptic seizures: a consecutive case series

BACKGROUND

Research has demonstrated that implementation of Nocebo Hypothesis Cognitive Behavioural Therapy (NH-CBT) achieved full symptom remission in 93% of people with Functional Neurological Symptoms Disorder (FNSD), most of them exhibiting motor symptoms. The basis for NH-CBT is consistent with a predictive coding aetiological model of FNSD. This idea is transparently shared with people with FNSD in the form of telling them that their symptoms are caused by a nocebo effect, usually followed by some physical activity that aims to change the person's belief about their body.

AIMS

To demonstrate that a version of NH-CBT can also be effective in eliminating or reducing non-epileptic seizures (assumed to be a sub-type of FNSD).

METHOD

A consecutive case series design was employed. Participants were treated with NH-CBT over a 12-week period. The primary outcome measure was seizure frequency. Numerous secondary measures were employed, as well as a brief qualitative interview to explore participants' subjective experience of treatment.

RESULTS

Seven out of the 10 participants became seizure free at least 2 weeks before their post-treatment assessment, and all stayed seizure-free for at least 5 months. Six of those seven remained seizure free at 6-month follow-up. There were large positive effect sizes for the majority of secondary measures assessed.

CONCLUSIONS

This case series provides evidence of feasibility and likely utility of NH-CBT in reducing the frequency of non-epileptic seizures.

Scoping review and expert-based consensus recommendations for assessment and management of psychogenic non-epileptic (functional) seizures (PNES) in children: A report from the Pediatric Psychiatric Issues Task Force of the International League Against Epilepsy

Limited guidance exists regarding the assessment and management of psychogenic non-epileptic seizures (PNES) in children. Our aim was to develop consensus-based recommendations to fill this gap. The members of the International League Against Epilepsy (ILAE) Task Force on Pediatric Psychiatric Issues conducted a scoping review adhering to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-SR) standards. This was supplemented with a Delphi process sent to pediatric PNES experts. Consensus was defined as ≥80% agreement. The systematic search identified 77 studies, the majority (55%) of which were retrospective (only one randomized clinical trial). The primary means of PNES identification was video electroencephalography (vEEG) in 84% of studies. Better outcome was associated with access to counseling/psychological intervention. Children with PNES have more frequent psychiatric disorders than controls. The Delphi resulted in 22 recommendations: Assessment-There was consensus on the importance of (1) taking a comprehensive developmental history; (2) obtaining a description of the events; (3) asking about potential stressors; (4) the need to use vEEG if available parent, self, and school reports and video recordings can contribute to a "probable" diagnosis; and (5) that invasive provocation techniques or deceit should not be employed. Management-There was consensus about the (1) need for a professional with expertise in epilepsy to remain involved for a period after PNES diagnosis; (2) provision of appropriate educational materials to the child and caregivers; and (3) that the decision on treatment modality for PNES in children should consider the child's age, cognitive ability, and family factors. Comorbidities-There was consensus that all children with PNES should be screened for mental health and neurodevelopmental difficulties. Recommendations to facilitate the assessment and management of PNES in children were developed. Future directions to fill knowledge gaps were proposed.

Illness-Promoting Psychological Processes in Children and Adolescents with Functional Neurological Disorder

Previous studies suggest that subjective distress in children with functional neurological disorder (FND) is associated with stress-system dysregulation and modulates aberrant changes in neural networks. The current study documents illness-promoting psychological processes in 76 children with FND (60 girls and 16 boys, aged 10.00-17.08 years) admitted to the Mind-Body Program. The children completed a comprehensive family assessment and self-report measures, and they worked with the clinical team to identify psychological processes during their inpatient admission. A total of 47 healthy controls (35 girls and 12 boys, aged 8.58-17.92 years) also completed self-report measures, but were not assessed for illness-promoting psychological processes. Children with FND (vs. controls) reported higher levels of subjective distress (total DASS score, t(104.24) = 12.18; p ˂ 0.001) and more adverse childhood experiences across their lifespans (total ELSQ score, t(88.57) = 9.38; p ˂ 0.001). Illness-promoting psychological processes were identified in all children with FND. Most common were the following: chronic worries about schoolwork, friendships, or parental wellbeing (n = 64; 84.2%); attention to symptoms (n = 61; 80.3%); feeling sad (n = 58; 76.3%); experiencing a low sense of control (helplessness) in relation to symptoms (n = 44; 57.9%); pushing difficult thoughts out of mind (n = 44; 57.9%); self-critical rumination (n = 42; 55.3%); negative/catastrophic-symptom expectations (n = 40; 52.6%); avoidance of activities (n = 38; 50%); intrusive thoughts/feelings/memories associated with adverse events (n = 38, 50%); and pushing difficult feelings out of mind (n = 37; 48.7%). In children with FND-disabled enough to be admitted for inpatient treatment-illness-promoting psychological processes are part of the clinical presentation. They contribute to the child's ongoing sense of subjective distress, and if not addressed can maintain the illness process. A range of clinical interventions used to address illness-promoting psychological processes are discussed, along with illustrative vignettes.

Sense of control, selective attention, cognitive inhibition, and psychosocial outcomes after Retraining and Control Therapy (ReACT) in pediatric functional seizures

BACKGROUND

Differences in sense of control, cognitive inhibition, and selective attention in pediatric functional seizures (FS) versus matched controls implicate these as potential novel treatment targets. Retraining and Control Therapy (ReACT), which targets these factors, has been shown in a randomized controlled trial to be effective in improving pediatric FS with 82% of patients having complete symptom remission at 60 days following treatment. However, post-intervention data on sense of control, cognitive inhibition, and selective attention are not yet available. In this study, we assess changes in these and other psychosocial factors after ReACT.

METHODS

Children with FS (N = 14, Mage = 15.00, 64.3% female, 64.3% White) completed 8 weeks of ReACT and reported FS frequency at pre and post-1 (7 days before and after ReACT). At pre, post-1, and post-2 (60 days after ReACT), all 14 children completed the Pediatric Quality of Life Inventory Generic Core Scales, Behavior Assessment System (BASC2), and Children's Somatic Symptoms Inventory-24 (CSSI-24), and 8 children completed a modified Stroop task with seizure symptoms condition in which participants are presented with a word and respond to the ink color (e.g., "unconscious" in red) to assess selective attention and cognitive inhibition. At pre and post-1, ten children completed the magic and turbulence task (MAT) which assesses sense of control via 3 conditions (magic, lag, turbulence). In this computer-based task, participants attempt to catch falling X's while avoiding falling O's while their control over the task is manipulated in different ways. ANCOVAs controlling for change in FS from pre- to post-1 compared Stroop reaction time (RT) across all time points and MAT conditions between pre and post-1. Correlations assessed the relationships between changes in Stroop and MAT performance and change in FS from pre- to post-1. Paired samples t-tests assessed changes in quality of life (QOL), somatic symptoms, and mood pre to post-2.

RESULTS

Awareness that control was manipulated in the turbulence condition of the MAT increased at post-1 vs. pre- (p = 0.02, η2 = 0.57). This change correlated with a reduction in FS frequency after ReACT (r = 0.84, p < 0.01). Reaction time significantly improved for the seizure symptoms Stroop condition at post-2 compared to pre- (p = 0.02, η2 = 0.50), while the congruent and incongruent conditions were not different across time points. Quality of life was significantly improved at post-2, but the improvement was not significant when controlling for change in FS. Somatic symptom measures were significantly lower at post-2 vs. pre (BASC2: t(12) = 2.25, p = 0.04; CSSI-24: t(11) = 4.17, p < 0.01). No differences were observed regarding mood.

CONCLUSION

Sense of control improved after ReACT, and this improvement was proportional to a decrease in FS, suggesting this as a possible mechanism by which ReACT treats pediatric FS. Selective attention and cognitive inhibition were significantly increased 60 days after ReACT. The lack of improvement in QOL after controlling for change in FS suggests QOL changes may be mediated by decreases in FS. ReACT also improved general somatic symptoms independent of FS changes.

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.

Management of Functional Seizures and Functional Movement Disorder: A Cross-Sectional Comparative Study

INTRODUCTION

Functional neurological disorders (FND) are conditions that cause to alterations in nervous system functions. They are disabling and impair the quality of life of patients but that are potentially reversible provided they have specific management. Functional seizures (FS) and functional movement disorder (FMD) are among the most common subtypes. Studies suggest a strong overlap between FS and FMD; however, there are still no cross-sectional studies that compare the management between these two conditions. Thus, our focus was to carry out a research that compares how these two subtypes of FND are being managed, in addition to assessing rates of understanding and acceptance of a diagnosis of FND.

METHODS

It is a cross-sectional study with data collected from medical records and interviews with two patients' groups (FS and FMD) treated from a FND clinic of the public health system of Brazil.

RESULTS

From 105 medical records of patients with FND analyzed, 60 participants were eligible and agreed to participate in this research, being FS (n = 31) and FMD (n = 29). Statistically significant differences (p < 0.05) were found in the use of antiseizure (FS > FMD), opioids (FMD > FS), multi-professional follow-up (FMD > FS) and rates of understanding and acceptance of an FND diagnosis (FMD > FS). Similarities were found in sociodemographic profiles, medical follow-up, psychiatric comorbidities and use of antidepressants, anxiolytics, antipsychotics and mood stabilizers between two conditions.

CONCLUSION

More similarities than differences in management were found between FS and FMD. Similarities may be related to overlaps in sociodemographic and clinical characteristics between the two groups. Differences may be related to specific issues of each patient and condition. Regardless of the group, patients who perform psychotherapeutic follow-up have higher rates of understanding and acceptance of an FND diagnosis.
