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

Functional neurological disorder, physical activity and exercise: What we know and what we can learn from comorbid disorders

Functional neurological disorder (FND) is a common neurologic disorder associated with many comorbid symptoms including fatigue, pain, headache, and orthostasis. These concurrent symptoms lead patients to accumulate multiple diagnoses comorbid with FND, including fibromyalgia, chronic fatigue syndrome, postural orthostatic tachycardia syndrome, persistent post-concussive symptoms, and chronic pain. The role of physical activity and exercise has not been evaluated in FND populations, though has been studied in certain comorbid conditions. In this traditional narrative literature review, we highlight some existing literature on physical activity in FND, then look to comorbid disorders to highlight the therapeutic potential of physical activity. We then consider abnormalities in the autonomic nervous system (ANS) as a potential pathophysiological explanation for symptoms in FND and comorbid disorders and postulate how physical activity and exercise may provide benefit via autonomic regulation.

Recent advances in understanding the neurobiology of pediatric functional neurological disorder

INTRODUCTION

Functional neurological disorder (FND) is a neuropsychiatric disorder that manifests in a broad array of functional motor, sensory, or cognitive symptoms, which arise from complex interactions between brain, mind, body, and context. Children with FND make up 10%-20% of presentations to neurology services in children's hospitals and up to 20% of adolescents admitted to hospital for the management of intractable seizures.

AREAS COVERED

The current review focuses on the neurobiology of pediatric FND. The authors present an overview of the small but growing body of research pertaining to the biological, emotion-processing, cognitive, mental health, physical health, and social system levels.

EXPERT OPINION

Emerging research suggests that pediatric FND is underpinned by aberrant changes within and between neuron-glial (brain) networks, with a variety of factors - on multiple system levels - contributing to brain network changes. In pediatric practice, adverse childhood experiences (ACEs) are commonly reported, and activation or dysregulation of stress-system components is a frequent finding. Our growing understanding of the neurobiology of pediatric FND has yielded important flow-on effects for assessing and diagnosing FND, for developing targeted treatment interventions, and for improving the treatment outcomes of children and adolescents with FND.

Functional Neurological Disorder in Saudi Arabia: An Update

Functional neurological disorder (FND) is characterized by neurological symptoms that lack congruence with traditional neurological diagnoses. Historically viewed through a Freudian psychoanalytic lens, FND has been conceptualized as a purely psychogenic disorder. However, the contemporary biopsychosocial perspective on FND emphasizes contributions of cognitive and neural circuit dysfunction and the disabling and involuntary nature of the illness. In Saudi Arabia, evidence suggests the prevalence of FND is significant. However, clinical programs and research focused on FND have been lacking. Studies from the region indicate that practitioners may have outdated views of FND. To address this, this narrative review provides an updated perspective on FND that is relevant to Saudi Arabia and the region. It delves into the evolving perception of FND, its underlying pathophysiology, risk factors, clinical presentations, and recent diagnostic and management advances. Unique features of FND in Saudi Arabia may include a significant role for family disputes as a risk factor, prevalent supernatural perceptions of FND, high prevalence of somatization, and cognitive dysfunction, and a potential favorable prognosis. The article concludes by providing the following recommendations related to FND in Saudi Arabia and the region: i) building educational programs to update clinicians about contemporary biopsychosocial perspectives on FND; ii) emphasizing a positive diagnostic approach based on clinical findings in FND; iii) instituting multidisciplinary programs to care for FND patients; iv) supporting systematic research efforts to explore culture-specific FND risk factors, patient outcome measures, and attitudes toward the disorder; v) developing national FND clinical practice guidelines; and vi) launching awareness campaigns to reduce FND stigma.

Outpatient Motor Retraining for Functional Movement Disorder: Predictors of a Favorable Short-Term Response

Background

Treating functional movement disorder (FMD) with motor retraining is effective but resource intensive.

Objectives

Identify patient, disease, and program variables associated with favorable treatment outcomes.

Methods

Retrospective review of the 1 week intensive outpatient FMD program at Mayo Clinic in Minnesota from February 2019 to August 2021. Outcomes included patient-reported measures (Canadian Occupational Performance Measure-Performance and Satisfaction subscales [COPM-P and COPM-S, range 0-10] and Global Rating of Change [GROC, -7 to +7]) and a retrospective investigator-rated scale (0-3, worse/not improved to significantly improved/resolved). Linear regression models identified variables predicting favorable outcomes.

Results

Participants (n = 201, 74% female, mean age = 46) had median FMD duration of 24 months. The commonest FMD subtypes were gait disorder (65%), tremor (41%) and weakness (17%); 53% had ≥2 subtypes. Most patients (88%) completed a therapeutic screening process before program entry. Patient-reported outcomes at the end of the week improved substantially (COPM-P average change 3.8 ± 1.9; GROC post-program average 5.5 ± 1.7). Available investigator-rated outcomes from short-term follow-up were also positive (102/122 [84%] moderately to significantly improved/resolved). Factors predicting greater improvement in COPM-P were completing therapeutic screening, higher number of non-motor symptoms, shorter FMD duration, earlier program entry, lower baseline COPM scores, and (among screened patients) higher GROC between therapeutic screening and program start.

Conclusion

Patients with diverse FMD subtypes improved substantially over a 1 week period. Utilization of therapeutic screening and greater improvement between therapeutic screening and program start were novel predictors of favorable outcomes. Non-motor symptoms did not preclude positive responses, although patients with predominant non-motor burden were excluded.

Pediatric Functional Neurologic Disorders

Functional neurologic disorders are common in the pediatric population. Recently, there has been a renewed focus on functional neurologic disorders, leading to improvements in diagnosis and management. This review focuses on updates in clinical presentation, diagnosis, pathophysiology (including neuroimaging), and treatment of functional neurologic disorders in the pediatric population.

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.

Functional neurological disorder in children and young people: Incidence, clinical features, and prognosis

AIM

To report incidence, demographic and clinical characteristics, and symptom outcome of functional neurological disorder (FND) in children.

METHOD

Children diagnosed with FND at a regional children's hospital were prospectively recruited by weekly active surveillance for 36 months. Demographic, clinical, and follow-up data were retrospectively extracted by review of electronic records. Descriptive statistical analyses were used.

RESULTS

Ninety-seven children (age range 5-15 years) met the case definition of FND (annual incidence 18.3 per 100 000 children). Children with FND were likely to be female (n = 68 [70%]) and older (median 13 years) with no difference in the Scottish Index of Multiple Deprivation (marker of socioeconomic status) compared with the general childhood population. Functional motor (41%) and sensory (41%) symptoms were most common; other somatic symptoms such as headache (31%) and pain (27%) were frequent. Self-reported psychiatric symptoms and infection/inflammation were the most common predisposing and precipitating factors respectively. At a median of 15 months follow-up, 49% of 75 children reported improvement or resolution of FND symptoms with no prognostic factors found.

INTERPRETATION

At this regional centre, FND in children had a higher incidence than previously reported and a less optimistic outcome than in some other studies.

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.

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.

Changing the culture of care for children and adolescents with functional neurological disorder

As members of a multidisciplinary team of professionals who treat children and adolescents with functional neurological (conversion) disorder (FND), we highlight the pressing need to develop an FND-informed culture of care that takes into account recent advances in our understanding of this group of patients. Stories of clinical encounters in health care settings from around the world-told by children and adolescents with FND, their parents, and health professionals-portray an outdated culture of care characterized by iatrogenic stigma, erosion of empathy and compassion within the clinician-patient relationship, and a lack of understanding of FND and its complex neurobiology. After a brief exploration of the outdated culture, we share our counterstories: how we and our colleagues have worked, and continue to work, to create an FND-informed culture in the health systems where we practice. We discuss the therapeutic use of child-friendly language. We also discuss a range of structural, educational, and process interventions that can be used to promote FND-informed beliefs and attitudes, FND-informed clinician-patient encounters, and FND-informed referral processes, treatment pathways, and therapeutic interventions.

Case Report: Parental Loss and Childhood Grief During COVID-19 Pandemic

The coronavirus disease 2019 (COVID-19) pandemic is an unprecedent public health crisis, transforming many aspects of our daily life. Protection measures, such as social distancing, nationwide lockdowns, and restrictions on hospital visits and funerals have a serious impact on how people mourn their loved ones. The grieving process during childhood and adolescence evolves along the developmental stages and is a dynamic, non-linear process that needs time. Parental death increases the risk for psychopathology in the short and long term. We present a case of an 11-year-old girl referred to child psychiatry-liaison service by her neurologist due to peer relationship problems and sadness. Fifteen days before her first psychiatric consultation, her father suffered a myocardial infarction complicated with hypoxic ischemic encephalopathy, and he was hospitalized in the intensive care unit. Positive coping mechanisms and adaptive emotional expression strategies were explored during her consultations. Her father died 2 weeks after emergency state and nationwide lockdown was declared in Portugal, during the first COVID-19 outbreak. The family did not have the opportunity for a proper farewell, the funeral obeyed strict rules, and the patient and her family were at home, due to social distancing and school closure policies. Consultations were maintained by telephone calls and, less frequently, by face-to-face appointments. Adaptive and helpful strategies to grieve were shared with the patient and her mother. Intervention with the mother alone was also helpful. Death circumstances related to COVID-19, confinement policies, and social-economical stressors can intensify the grief experience, increasing the risk for complicated grief. Although psychiatric teleconsultation is essential during COVID-19 pandemic, it poses various limitations. Non-verbal communication clues may not be totally apprehended; it may represent a problem in the therapeutic relationship, and access to technology can be difficult for psychiatric patients and clinicians. COVID-19 pandemic policies should include mental health protection measures, which should facilitate adjusted grief responses for those who lose a loved one during this pandemic.
