Pediatric psychogenic nonepileptic seizures: a study of assessment tools

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.

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.

Behavioral health screening in pediatric epilepsy: Which measures commonly used in the United States are 'good enough'?

PURPOSE

To improve evidence-based implementation of behavioral health screening measures in pediatric epilepsy care, guidance is needed in the selection and interpretation of evidence-based screening measures. Therefore, the goals of this project were to (1) evaluate the clinical utility and psychometric properties of screening instruments frequently used in the United States (US) for anxiety, depression, and behavior problems in youth with epilepsy (YWE), and (2) provide guidance around selection and interpretation of these behavioral health screening measures.

METHOD

The critique was conducted in three phases: (1) identification of articles based on search criteria; (2) full review of articles for eligibility assessment; (3) evaluation of screening measures and organization into Tiers. Nine behavioral health measures frequently used to screen for anxiety, depression, and disruptive behaviors in the US were selected for evaluation. PubMed, CINAHL, Medline, and APA databases were searched using the following search terms: [target area] + [screening measure] + epilepsy + children [youth], [adolescents]. Inclusion/exclusion criteria for articles were as follows: (1) focused on YWE, (2) written in English, and (3) conducted in the US. Once articles were selected, Hunsley and Mash's criteria were used to evaluate and categorize the screening measures' psychometric properties, which have clear relevance to clinical practice. Measures were also classified into three tiers by the level of validation according to established evidence-based criteria.

RESULTS

Forty-one unique papers were identified through the literature search and assessed as eligible. Evaluation of screening measures revealed only two psychometrically sound measures that met criteria for Tier 1, the NDDI-E-Y and the Pediatric NeuroQoL-Depression, both depression screening measures. Several additional depression screening measures met criteria for Tier 2 (CDI-2, BASC-2-Depression Scale, and CBCL Withdrawn/Depressed Scale). Anxiety screening measures have not been validated in pediatric epilepsy and thus only met the criteria for Tier 2 (BASC-2 Anxiety Scale, CBCL DSM-IV Oriented Anxiety Problems Scale, MASC). Similarly for disruptive behaviors, two measures met Tier 2 criteria (BASC-2 Externalizing Problems Index, CBCL Externalizing Problems Index).

CONCLUSION

Strides have been made in the validation of behavioral health screening measures for YWE; however, continued research in this area is necessary to validate existing psychometrically sound measures and to develop and evaluate epilepsy-specific measures in the pediatric epilepsy population.

Psychiatric and personality factors in pediatric functional seizures: A prospective case-control study

PURPOSE

This study assessed psychiatric and personality characteristics in relation to pediatric functional seizures (FS).

METHODS

In a 1:1 prospectively matched-control study design, children with documented FS (confirmed via video EEG; ages 13-18) were matched to controls (MCs) on income, sex, race, and age. Primary outcomes were Behavior Assessment System for Children, Second Edition (BASC-2) and Millon Adolescent Clinical Inventory (MACI). Secondary measures included questionnaires assessing trauma, somatization, body awareness and quality of life (QOL). T-tests investigated differences between groups on T-scores. Due to lack of significant outcomes, an experimental analysis was conducted assessing differences in number of clinically elevated BASC-2 and MACI scores between groups. Binary logistic regressions determined the influences of clinically elevated scores on likelihood participants have FS. T-tests assessed differences on secondary measures.

RESULTS

Participants included 84 children, 42 with FS and 42 MCs (Children with FS: Mean_age=15.4, Interquartile Range_age=3; 73.5% female; 59.5% white). Children with FS had greater parent-reported somatization (t(23)=5.67, p<0.001) on BASC-2, greater somatization on CSSI-24 (t(35)=6.83, p<0.001), and poorer QOL (t(41)=-6.22; p<0.001) than MCs. There were no differences in clinically elevated BASC-2 or MACI scores compared to MCs and clinically elevated scores did not influence likelihood participants have FS.

CONCLUSIONS

Children with FS had greater somatization and poorer QOL but similar rates of psychiatric symptoms, trauma, and maladaptive personality traits compared to MCs. Psychiatric or personality factors did not predict likelihood of FS. Explanations of pediatric FS should consider novel contributors to FS rather than relying solely on a psychiatric etiology.

Psychogenic non-epileptic seizures in youth: Individual and family psychiatric characteristics

INTRODUCTION

Youth with psychogenic non-epileptic seizures (PNES) are an understudied group associated with significant medical and psychiatric morbidity. Several studies have examined characteristics associated with youth's development of this disorder, though the exploration of family factors including psychiatric illness, has been lacking. This study sought to establish the need for a more comprehensive future study.

METHODS

A retrospective chart review was conducted on patients who had been admitted and diagnosed with PNES at the epilepsy monitoring unit at Children's Hospitals and Clinics of Minnesota. A total of 62 patients were included. All patients were evaluated by an epileptologist and psychologist during their diagnostic admission. "Spells" in question were captured via video EEG monitoring. PNES youth and family risk factors were assessed.

RESULTS

Mean age of PNES symptom onset was 13.9 years. Patients (73%) were diagnosed within 6 months of onset of symptoms. Histories of other impairing somatic complaints were present in the youth (54%), with 67% having prior psychiatric diagnoses. Experiencing suicidal ideation or thoughts of self-harm occurred in 47% of this sample. Family members were unaware of the history of these symptoms with 12% of the parent's reporting awareness. Family history of psychiatric disorders (first-degree relatives of patient) was present in 54% of the sample, with anxiety, depression and conversion disorder being the most commonly endorsed diagnoses.

CONCLUSIONS

Youth with PNES present with comorbid psychiatric disorders, though prior assessment and treatment for these disorders was not common. Youth with PNES have history of suicidal ideation and thoughts of self-harm, though parental awareness of these co-occurring symptoms is limited. Family risk factors, such as history of psychiatric disorder in first degree relatives, was high. The impact of these family risk factors is understudied and should be further evaluated to better understand the impact on development and maintenance of this disorder in youth.

Title: Functional seizures across the adult lifespan: female sex, delay to diagnosis and disability

OBJECTIVE

The clinical characteristics of functional seizures may vary based on age-of-onset or age-of-presentation. Description of age-related differences has focused on three categories: pediatric, young-adult, and older-adult. We evaluated how factors continuously varied based on age-of-presentation across the adult lifespan.

METHODS

Based on cross-sectional data from 365 adult (18 to 88 years old) patients with documented diagnoses of functional seizures, we evaluated how the quantity and prevalence of specific ictal behaviors, historical factors, and comorbidities varied based on patient age-of-presentation using sequential weighted averages.

RESULTS

Four factors changed prominently with age-of-presentation: female predominance decreased at two inflection points - ages 35 and 62; the prevalence of work disability was higher until age-of-presentation 30 then plateaued at 80%; there was greater delay to diagnosis in older patients; and comorbidities was higher with age-of-presentation, starting from early adulthood. The proportion of patients who presented with functional seizures decreased after 50. Ictal behavior did not substantially vary with age-of-presentation.

CONCLUSION

The time from onset to diagnosis increased with age-of-presentation, which may be related to increased comorbidities and the misconception that FS do not start in older age. The female predominance decreased nonlinearly with age. By age 30, most patients' seizures already had substantial association with unemployment. These findings emphasize that patients can develop functional seizures at any age. The rapid development of disability relatively early in life, which then stays at a high prevalence rate, demonstrates the need for prompt referral for definitive diagnosis and treatment.

Psychiatric Disorders in Children and Adolescents With Psychogenic Nonepileptic Seizures

OBJECTIVE

Knowledge regarding psychiatric disorders in children and adolescents with psychogenic nonepileptic seizures (PNES) is limited. This study outlines the spectrum and risk of psychiatric disorders in childhood-onset PNES.

METHODS

We performed a nationwide matched cohort study of children and adolescents with PNES 5 to 17 years of age at the time of diagnosis between January 1, 1996, and December 31, 2014. Two matched comparison groups were included: children and adolescents with epilepsy (ES) and children and adolescents without PNES or epilepsy, called healthy controls (HC). Outcomes were prevalent psychiatric disorders before index (i.e., date of diagnosis or corresponding date for HC) and incident psychiatric disorders 2 years after index. Relative risks (RRs) were calculated and adjusted for potential confounders.

RESULTS

We included 384 children and adolescents with validated PNES, 1,152 with ES, and 1,920 HC. Among the cases of PNES, 153 (39.8%) had prevalent psychiatric disorders and 150 (39.1%) had incident psychiatric disorders. Compared to the ES and HC groups, children and adolescents with PNES had elevated risks of both prevalent psychiatric disorders (adjusted RR_PNES/ES 1.87, 95% confidence interval [CI] 1.59-2.21, adjusted RR_PNES/HC 5.54, 95% CI 4.50-6.81) and incident psychiatric disorders (adjusted RR_PNES/ES 2.33, 95% CI 1.92-2.83, adjusted RR_PNES/HC 8.37, 95% CI 6.31-11.11). A wide spectrum of specific psychiatric disorders displayed elevated RRs.

CONCLUSIONS

Children and adolescents with PNES are at higher risk of a wide range of psychiatric disorders compared to children and adolescents with ES and HC. A careful psychiatric evaluation is warranted to optimize and individualize treatment.

Psychopathological features in referred adolescents with psychogenic nonepileptic seizures with or without epilepsy

Psychogenic nonepileptic seizures (PNES) are episodic manifestations that mimic epileptic seizures (ES) although not associated with electroencephalogram (EEG) abnormalities. Psychogenic nonepileptic seizures and ES, however, can often cooccur. Emotional distress in adolescents can trigger PNES, but the psychopathological and personality features are still unknown. The aim of this study was to explore psychopathological features in a sample of referred youth with PNES, with or without ES, compared with a control group with ES. Thirty-four patients aged 12 to 21 years, 19 females and 15 males, were included in the study, 15 patients with PNES, 7 with PNES and ES, and 12 with ES. The three groups were compared according to psychiatric categorical diagnoses, psychopathological dimensions, life stressors, and personality traits, including alexithymia, interpersonal reactivity, and resilience, all assessed with structured measures. Patients with PNES, with or without ES, were more severely impaired, had a higher incidence of mood disorders, more frequent lifetime traumatic experiences, and lower resilience. All the three groups presented alexythimic traits and emotional dysregulation. Major limitations are the small sample size and the lack of a control group of healthy subjects. Disentagling psychopathological characteristics in PNES can help clinicians to focus diagnostic approaches and therapeutic interventions.

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.

Sibling-Controlled Study of Parental Bonding, Coping, and Urgent Health-Care Use in Families With Children With Nonepileptic Seizures

Objectives

Pediatric psychogenic nonepileptic seizures (PNES) is a functional somatic symptom condition with significant health-care service burden. While both family and individual factors play an important role in the development and maintenance of PNES, little is known about what predicts urgent health-care use in families with children who have PNES. The aim of the current study was to explore whether child coping and parental bonding styles influence the decision to seek urgent medical care in these families.

Methods

Data were analyzed from youth of age 8-18 years, 47 with PNES, and their 25 sibling controls. Parents provided the number of youth emergency room visits and hospitalizations in the preceding year. Youth completed a questionnaire about their coping styles and a measure about their mothers' and fathers' bonding styles. Using a mixed model with family as a random effect, we regressed urgent health-care use on participant type (youth with PNES or sibling), parental bonding style, and youth coping style, controlling for number of child prescription medications.

Results

Higher urgent health-care use was associated with having PNES, coping via monitoring, and perceiving one's father to be rejecting and overprotective. Lower urgent health-care use was associated with coping via venting and with perceiving one's mother to be caring and overprotective.

Conclusions

This study provides preliminary empirical support for family-based clinical efforts to reduce child urgent health-care use by enhancing effective child coping skills and improving parental response to child impairment and distress in families with youth with PNES.

Pediatric Psychogenic Nonepileptic Seizures: A Concise Review

Psychogenic nonepileptic seizures is a complicated biopsychosocial disorder with significant morbidity and high cost in children's social, emotional, family, and academic functioning as well as health care service utilization. Misdiagnosis and diagnostic delay, resulting from both lack of access to approved standards for diagnosing and service providers comfortable with diagnosing and treating this disorder, impact prognosis. Treatment in close proximity to symptom onset is thought to provide the best chance for remission.

Psychogenic Nonepileptic Seizures: Diagnosis, Management, and Bioethics

BACKGROUND

The diagnosis and management of psychogenic nonepileptic seizures (PNES) is often challenging and fraught with discord and disagreement between patients, parents, and physicians. Furthermore, there are ethical challenges when making the diagnosis, communicating this information, and instituting management.

METHODS

We reviewed the current body of knowledge regarding the characteristic differences between epileptic seizures and PNES, and the high incidence of psychiatric comorbidities. An ethical analysis was made of diagnosis and management based on ethical principles, virtue ethics, and the social contract that health professionals have with patients.

RESULTS

Key distinctions between PNES and epilepsy lie in both patient and seizure characteristics. Long duration, eye closure, asynchronous movements, frequent recurrence in the same context, intra-ictal awareness, and lack of post ictal state are useful in helping establish the diagnosis. Psychiatric comorbidities, history of abuse, cognitive impairment, and multiple non specific somatic complaints are some salient patient features that should increase suspicion for the diagnosis of PNES. However, definitive diagnosis rests on capturing the events on video EEG.

CONCLUSION

Effective diagnosis and management of PNES requires the use of video EEG and an early collaborative approach between pediatricians, neurologists, psychiatrists, nursing staff, and other professional colleagues. Ethical questions that may arise should be addressed with the virtues of competence, courage, compassion, prudence, and honesty; and the principles of respect beneficence, and the avoidance of unnecessary harm.

Psychogenic Paroxysmal Nonepileptic Events in Children: A Review

BACKGROUND

Paroxysmal nonepileptic events are common in children. Events with a psychological basis, historically referred to as pseudoseizures, are a large subset of paroxysmal nonepileptic events.

METHODS

A review of the relevant pediatric and adult literature was performed.

RESULTS

It was found that these events have many semioloigc features similar to epileptic events and can be challenging to correctly identify. The use of a detailed history in combination with video encephalography and knowledge of psychogenic paroxysmal nonepileptic events will facilitate making the correct diagnosis. Paroxysmal nonepileptic events are important to identify as comorbid disorders such as depression, anxiety disorder, family discord, and school issues are frequent. In addition, prior sexual, emotional, and/or physical abuse may be present.

CONCLUSIONS

Pediatric patients with paroxysmal nonepileptic events need to be recognized in order to avoid unnecessary antiepileptic drugs and emergency department or hospital visits and to facilitate appropriate psychological intervention to address the underlying etiologies. This review will focus on evaluation and identification of paroxysmal nonepileptic events, in addition to reviewing the various comorbidities, effective treatments, and outcomes for pediatric patients. The key differences between pediatric and adult patients with paroxysmal nonepileptic events are addressed.

Ethical dilemmas in pediatric and adolescent psychogenic nonepileptic seizures

To date, only a very narrow window of ethical dilemmas in psychogenic nonepileptic seizures (PNES) has been explored. Numerous distinct ethical dilemmas arise in diagnosing and treating pediatric and adolescent patients with PNESs. Important ethical values at stake include trust, transparency, confidentiality, professionalism, autonomy of all stakeholders, and justice. In order to further elucidate the ethical challenges in caring for this population, an ethical analysis of the special challenges faced in four specific domains is undertaken: (1) conducting and communicating a diagnosis of PNESs, (2) advising patients about full transparency and disclosure to community including patients' peers, (3) responding to requests to continue antiepileptic drugs, and (4) managing challenges arising from school policy and procedure. An analysis of these ethical issues is essential for the advancement of best care practices that promote the overall well-being of patients and their families.

Depression and epilepsy, pain and psychogenic non-epileptic seizures: clinical and therapeutic perspectives

The clinical manifestations of depression in people with epilepsy (PWE) are pleomorphic, often associated with anxiety symptoms and anxiety disorders. The ongoing debate of whether the clinical presentation of depression in PWE is unique to this neurologic disorder is reviewed. Comorbid depression can impact the recruitment of PWE for pharmacologic trials with antiepileptic drugs (AEDs). Yet, the impact of depression on the response of the seizure disorder to pharmacotherapy with AEDs and its impact on worse adverse events may bias the interpretation of the trial findings, particularly when depressed patients are included in the AED trials. PWE have a greater suicidal risk than the general population. This risk is mediated by multiple factors, and recent data from the FDA have imputed a potential pathogenic role to all AEDs. The recognition of patients at risk is reviewed. Yet, the validity of the FDA data has been questioned, and the status of this controversial question is analyzed. As in the case of epilepsy, depression and pain syndromes have a relatively high comorbidity. The negative impact of depression on pain is reminiscent of that of depression in PWE; furthermore, the high comorbidity may be also associated with the existence of common pathogenic mechanisms. Neurologists and in particular, epileptologists establish the diagnosis of psychogenic non-epileptic seizures (PNES) in whom a comorbid depressive disorder is very often identified. The role of depression in the course of PNES and its treatment are discussed. Scarce data are available on the treatment of depression in PWE. Thus, clinicians have had to adopt data from patients with primary depressive disorders. We outline a consensus strategy on the identification and treatment of depressive disorders in adult and pediatric patients with epilepsy.

Child psychiatry

This paper first summarizes the main findings of clinical studies conducted over the past two and a half decades on psychopathology (i.e., psychiatric diagnoses, behavior and emotional problems) in children with new onset and chronic epilepsy both with and without intellectual disability who are treated medically and surgically. Although impaired social relationships are core features of the psychiatric disorders found in pediatric epilepsy, few studies have examined social competence (i.e., social behavior, social adjustment, and social cognition) in these children. There also is a dearth of treatment studies on the frequent psychiatric comorbidities of pediatric epilepsy, attention deficit hyperactivity disorder, anxiety disorders, and depression. Drs. Hamiwka and Jones then describe their current and planned studies on social competence and cognitive behavioral treatment of anxiety disorders, respectively, in these children and how they might mitigate the poor long-term psychiatric and social outcome of pediatric epilepsy.

Approach to psychosomatic illness in adolescents

PURPOSE OF REVIEW

Due to the increased prevalence of psychosomatic presentations and the difficulty of managing such patients, this article summarizes the latest findings for identifying individual and family risk factors, and new trends in the evaluation and management of pediatric patients with psychosomatic illness.

RECENT FINDINGS

Up to 50% of patients in pediatric care will complain of medically unexplained symptoms with significant functional and emotional impairment. Such patients place heavy burdens on the healthcare system (frequent utilization of health resources and hospitalizations, specialist consultations, unnecessary investigations, and treatments). Somatoform disorders in pediatric care are associated with risks for psychiatric co-morbidity (anxiety and depressive disorders), family conflict, parent-perceived ill health, and school problems/absenteeism.

SUMMARY

Gaining expertise in addressing pediatric psychosomatic illness can make a great difference in patients' life and in physicians' professional satisfaction. Effective treatment approaches involve a multidisciplinary approach to consolidate care and facilitate communication, target the patient/family's understanding of the mind-body relationship and their acceptance of the bio-psycho-social formulation and treatment, and utilize functional rehabilitation and cognitive behavioral therapy for the individual and family and management guidance for schools.

Konversionsstörungen: Störungsbild, Diagnostik, Psychoedukation und Intervention

Konversionsstörungen umfassen nichtepileptische Anfälle sowie sensorische oder motorische Funktionsausfälle (Gangstörungen, Kraftverlust und Lähmung, Sprechstörungen) ohne organmedizinische Ursache. Sie nehmen in klassifikatorischer, ätiologischer und therapeutischer Hinsicht eine Zwischenstellung zwischen den somatoformen und dissoziativen Störungen ein. Bei hohen Raten psychopathologischer Vulnerabilität und Komorbidität können traumatische Erfahrungen, akute Belastungsfaktoren sowie aktuell überfordernde Entwicklungsaufgaben als Auslöser wirken. Besonders typisch ist ein emotional invalidierendes Familienklima, das den authentischen und direkten Ausdruck von Bedürfnissen und Befindlichkeiten des Kindes hemmt. Die Manifestation der Konversionssymptome erfüllt einerseits eine entlastende und verstärkende Funktion, erzeugt andererseits aber neue Belastungsfaktoren wie funktionelle Behinderung, Einschränkungen der sozialen und schulischen Teilhabe, hypochondrische Sorge vor einer unerkannten Grunderkrankung sowie Angst vor Stigmatisierung als Simulant oder psychisch Kranker. Ein Störungsmodell wird vorgestellt, das auch als Grundlage für einen Leitfaden zur klinisch-psychologischen Exploration, Anamneseerhebung, Fallkonzeption sowie das das Procedere der Diagnosemitteilung dient. Patientenorientierte Metaphern werden im Rahmen der Psychoedukation eingesetzt, um die Entstehung der Symptomatik trotz intakter neuronaler Reizleitung für Patient und Eltern nachvollziehbar zu gestalten. Die psychotherapeutische Intervention startet mit einer schrittweisen Wiederaufnahme altersgerechter Aktivitäten und Rollen. Physiotherapie zum Training der geschwächten Muskulatur wird initiiert, um dem Patienten ein Ritual anzubieten, das eine Wiederherstellung der Funktionsausfälle ohne Gesichtsverlust ermöglicht. Psychotherapeutische Strategien im engeren Sinne greifen die vorgegebene Dissoziation des Bewusstseins von der körperlichen Symptomatik auf. Altersgerecht wird dem Kind ein Persönlichkeitsanteil beschrieben, der die Symptomatik überwinden will, ein anderer Persönlichkeitsanteil wird gegenübergestellt, der die Konversionssymptomatik und dessen Anliegen repräsentiert. Der Therapeut entwickelt und moderiert mit dem Kind Lösungen, die geeignet sind, beide Persönlichkeitsanteile wieder neu zu integrieren und damit die Dissoziation zwischen Bewusstsein und körperlicher Symptomatik aufzulösen.
