Psychogenic nonepileptic seizures in pediatric population: A review

Psychoeducation interventions for people with non-epileptic seizures: A scoping review

BACKGROUND

Cognitive behavioural therapy (CBT) and other psychological approaches have a growing evidence base for treating Non-Epileptic Seizures (NES). However, communication about the diagnosis can be difficult for clinicians and is not always well received. It is thought that Psychoeducation about NES may improve engagement with treatment such as CBT and may contribute to reductions in the frequency of seizures and improvements in health related quality of life. However, psychoeducational components of treatment are often not evaluated in isolation meaning the specific benefit to patients is not currently well understood.

AIMS

The researchers aimed to examine the outcomes associated with psychoeducational interventions and the content of these programmes for NES.

METHOD

A scoping review was undertaken across four databases with seventeen eligible studies identified which were charted to analyse the data.

RESULTS

Findings revealed that components and modalities of interventions varied as did methods of evaluating the interventions. A number of different outcome measures were used and not all studies reported the significance of findings. Results across studies were inconsistent; however, there was a general trend across the studies of symptom reduction and improvement in mental health.

CONCLUSIONS

Findings illustrate that psychoeducation has potential benefits as an intervention in its own right. However, it may be best placed as a second step in a stepped care model, between initial diagnosis and further psychological treatment. The present literature needs replication and more robust studies for more certain conclusions to be drawn.

The effects of racial and socioeconomic disparities on time to diagnosis and treatment of pediatric functional seizures in the United States

PURPOSE

The present study sought to assess the effects of racial and socioeconomic status in the United States on time to treatment and diagnosis of pediatric functional seizures (FS).

METHODS

Eighty adolescents and their parent/guardian completed a demographics questionnaire and reported date of FS onset, diagnosis, and treatment. Paired samples t-tests compared time between FS onset and diagnosis, onset and treatment, and diagnosis and treatment based on race (White vs racial minority), annual household income (≤$79,999 vs ≥$80,000), maternal and paternal education (≤Associate's Degree vs Bachelor's Degree), and combined parental education (≤Post-graduate training vs Graduate degree).

RESULTS

Adolescents with lower annual household income began treatment >6 months later than adolescents with greater annual household income (p = 0.049). Adolescents with lower maternal and paternal education (≤Associate's Degree vs Bachelor's Degree) began treatment >4 and ∼8.5 months later than adolescents with greater maternal and paternal education (p = 0.04; p = 0.03), respectively. Adolescents with lower maternal education also received a diagnosis >5 months later (p = 0.03). Adolescents without a mother or father with a graduate degree received a diagnosis and began treatment∼3 and >11 months later (p = 0.03; p = 0.01) than adolescents whose mother or father received a graduate degree, respectively. No racial differences were found.

CONCLUSIONS

Adolescents with lower annual household income and/or parental education experienced increased duration between FS onset and treatment and diagnosis. Research is needed to clarify the mechanisms underlying this relationship, and action is needed to reduce these disparities given FS duration is associated with poorer prognosis and greater effects on the brain.

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.

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.

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.

Adverse Childhood Experiences Are Associated With Seizures in Children: A Cross-sectional Analysis

Background and Objective

To assess the relationship between adverse childhood experiences (ACE/ACEs) and epilepsy.

Methods

We performed a cross-sectional retrospective cohort analysis using population-based data from the 2018 and 2019 National Survey of Children's Health to examine caregiver-reported ACE exposures and their relationship to caregiver-reported physician diagnoses of epilepsy or seizure disorder in children. ACEs elicited in the survey included questions about experience of violence, household dysfunction, and food and housing insecurity. Adjusting for age, race, and income level, we used logistic regression to test the relationships between cumulative ACE score and current seizure disorder or epilepsy diagnosis and to examine which specific ACEs were individually associated with current seizure disorder or epilepsy diagnosis.

Results

The study population consisted of 59,963 participants; 52.2% were female, and 47.8% were male. Participant ages ranged from 0 to 17 years. A current diagnosis of epilepsy or seizure disorder was reported in 377 (0.63%) participants, and 22,749 (37.9%) participants had one or more ACE exposures. As the number of ACEs increased, odds of current epilepsy or seizure disorder diagnosis increased by 1.14 (95% confidence interval 1.07-1.22). Five ACE exposures demonstrated a high association with a current diagnosis of epilepsy or seizure disorder: food/housing insecurity, witnessing domestic violence, household mental illness, neighborhood violence, and parent/guardian incarceration.

Discussion

Multiple ACE exposures were individually associated with reporting a diagnosis of epilepsy or seizure disorder. An increase in cumulative ACE exposures increased odds of having current diagnosis of epilepsy or seizure disorder.

Pediatric Functional Neurological Disorder: Demographic and Clinical Factors Impacting Care

This is a multicenter retrospective EMR-based chart review of 88 patients aged 3-21 years admitted for evaluation of functional neurologic disorder (FND). We sought to establish characteristics associated with FND, calculate incidence of abnormal neurodiagnostic findings, and determine features associated with variability in workup and treatment. FND patients were 65% female, 40% White, 33% Hispanic, and 88% primarily English speaking with median 13.9 years. We detected variability in management by age, ethnicity, psychiatric comorbidity, and hospital site. Our findings suggest limited utility to CTs in this setting (100% normal) and that workup can be safely informed by physical exam, which predicted abnormal MRI and LP results. We favor screening for adverse childhood experiences in FND patients. Hospitalization may be a rare opportunity for psychiatry contact.

Gastrointestinal and Autonomic Symptoms—How to Improve the Diagnostic Process in Panayiotopoulos Syndrome?

One of the most common epileptic disorders in the pediatric population is Panayiotopoulos syndrome. Clinical manifestations of this idiopathic illness include predominantly autonomic symptoms and dysfunction of the cardiorespiratory system. Another feature constitutes prolonged seizures that usually occur at sleep. It is crucial to differentiate the aforementioned disease from other forms of epilepsy, especially occipital and structural epilepsy and non-epileptic disorders. The diagnostic process is based on medical history, clinical examination, neuroimaging and electroencephalography—though results of the latter may be unspecific. Patients with Panayiotopoulos syndrome (PS) do not usually require treatment, as the course of the disease is, in most cases, mild, and the prognosis is good. The purpose of this review is to underline the role of central autonomic network dysfunction in the development of Panayiotopoulos syndrome, as well as the possibility of using functional imaging techniques, especially functional magnetic resonance imaging (fMRI), in the diagnostic process. These methods could be crucial for understanding the pathogenesis of PS. More data arerequired to create algorithms that will be able to predict the exposure to various complications of PS. It also concerns the importance of electroencephalography (EEG) as a tool to distinguish Panayiotopoulos syndrome from other childhood epileptic syndromes and non-epileptic disorders.

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.

Brief Report: Psychogenic Nonepileptic Events in Pediatric Patients with Autism or Intellectual Disability

This is a retrospective case series of pediatric patients referred to the psychogenic nonepileptic events clinic (PNEE) who had comorbid diagnoses of autism spectrum disorder (ASD) or intellectual disability (ID). We describe 15 patients, nine with ASD and six with ID who had a telephone visit follow-up at 12 months. There were higher rates of male gender (40%) and comorbid epilepsy (53%) compared to the larger PNEE cohort. Eleven patients were available for follow-up and ten patients had improvement in events or were event-free. We report that patients with ASD or ID can develop PNEE and experience improvement from events.

Misdiagnosis of prolonged psychogenic non-epileptic seizures as status epilepticus: epidemiology and associated risks

OBJECTIVE

To determine the epidemiology of prolonged psychogenic non-epileptic seizures (pPNES) misdiagnosed as status epilepticus, as well as the risks associated with non-indicated treatment.

METHODS

We performed an individual patient data analysis from the Rapid Anticonvulsant Medication Prior to Arrival Trial (RAMPART) and the Established Status Epilepticus Treatment Trial (ESETT) to assess incidence, patient characteristics and clinical course of misdiagnosed pPNES.

RESULTS

Among 980 patients aged 8 years or older diagnosed and treated for status epilepticus in RAMPART and ESETT, 79 (8.1%) were discharged with a final diagnosis of pPNES. The relative incidence was highest in adolescents and young adults (20.1%). The typical female preponderance seen in that age bracket was not evident in children and older adults. Adverse effects, including respiratory depression and intubation, were documented in 26% of patients with pPNES receiving benzodiazepines in RAMPART and 33% of patients receiving additional second-line medication in ESETT. In ESETT, patients who were treated with benzodiazepines before hospital admission had higher rates of unresponsiveness and severe adverse effects than those treated after admission, suggesting cumulative effects of accelerated treatment momentum. Across trials, one in five patients with pPNES were admitted to an intensive care unit.

CONCLUSIONS

Misdiagnosis and treatment of pPNES as status epilepticus are a common and widespread problem with deleterious consequences. Mitigating it will require training of emergency staff in semiological diagnosis. Status epilepticus response protocols should incorporate appropriate diagnostic re-evaluations at each step of treatment escalation, especially in clinical trials.

[Psychogenic non-epileptic seizures]

The review provides epidemiological data and discuss the associated burden of non-epileptic seizures (PNES). Data on the prevalence, socio-demographic and clinical risk factors for the development of PNES are presented. The hypotheses of the PNES origin, including the contribution of psychological trauma, are considered. We also describe contemporary methods for differential diagnosis of epileptic seizures and PNES, including biomarkers and the use of diagnostic questionnaires. Special attention is given to the issues of the psychiatric comorbidity of PNES.

Outcomes of children and adolescents 1 year after being seen in a multidisciplinary psychogenic nonepileptic seizures clinic

OBJECTIVE

Psychogenic nonepileptic seizures (PNES) are paroxysmal events that may involve altered subjective experience and change in motor activity with a psychological cause. The aim of this work is to describe a population of pediatric patients with PNES and identify factors predictive of 12-month outcomes.

METHODS

We conducted a prospective observational study of children and adolescents referred to the multidisciplinary Nationwide Children's Hospital PNES clinic between November 2017 and July 2019. Information was collected from patients during clinic visits and semistructured follow-up phone calls. Descriptive statistics and Fisher exact test were used for analysis.

RESULTS

Of the 139 consecutive patients referred to the PNES clinic, 104 were seen in clinic and 63 answered 12-month follow-up calls. Patients with comorbid epilepsy had increased rates of participation at 12-month follow-up (p = .04). Complete remission was achieved by 32% (20/63) of patients at 12 months. Combined PNES remission and improvement was 89% (56/63) at 12 months. Patients and families who were linked with counseling at 1 month were more likely to achieve remission at 12 months (p = .005). Less than half (44%, 28/63) of patients reached at 12 months had their events documented on video-electroencephalogram (EEG) at diagnosis; however, those who did were not more likely to be accepting of the diagnosis at 12 months (p = 1.0), be linked with counseling at 12 months (p = .59), or be event-free at 12 months (p = .79).

SIGNIFICANCE

Remission occurred in one third of patients by 12 months; however, improvement in events was seen in 89%. Connection to counseling by 1 month was associated with increased remission rates at 12 months. Capturing events on video-EEG was not associated with increased acceptance or event freedom at 12 months. Diagnosis should be followed by strong encouragement to connect with counseling quickly to achieve a goal of increasing 12-month PNES remission rates.

PERCEPTIONS OF A MULTIDISCIPLINARY TEAM ON THE PSYCHOLOGICAL REPERCUSSIONS OF SEXUAL VIOLENCE AGAINST CHILDREN AND ADOLESCENTS

ABSTRACT Objective: to understand the perceptions of a multidisciplinary health team in caring for hospitalized children and adolescents with psychological repercussions of sexual violence, in the light of Symbolic Interactionism Theory. Method: this is a qualitative study, carried out with 30 professionals from the multidisciplinary health team working in a general public hospital in Salvador, Bahia, Brazil. The interviews took place between June and July 2019, using a semi-structured questionnaire and, after being recorded, the reports were transcribed. In analysis, the data were categorized by similar themes following the steps: pre-analysis, material exploration, treatment of results and interpretation. The project was approved by an Institutional Review Board. Results: among the psychological disorders presented by children and adolescents are aggressiveness, mutism, eating disorders, infantilized behavior, hypersexualized behaviors, depressive disorders, anxiety disorders, psychotic episodes, and delusions. Conclusion: the study demonstrates the perceptions resulting from the interaction allowed in caring for the multidisciplinary team to children and adolescents who experienced sexual violence and developed psychological disorders. In this way, it raises warning signs for family members, health professionals, education, protective devices and the whole of society about the need to observe signs of these changes on a daily basis, seeking to investigate their possible relationship with sexual assault.

Seizure mimics in children: An age-based approach

BACKGROUND

In order to distinguish seizure mimics from seizures in children it is important to clarify the event duration, frequency, semiology, and any precipitating factors.

METHODOLOGY

This review provides a succinct and up-to-date overview aimed at general and subspecialty non-neurologist pediatric and adolescent health care providers to help guide a diagnostic approach when a child presents with paroxysmal events of unclear etiology.

RESULTS

In many cases, seizure mimics are consistently triggered by an event, location, or emotion, and often resolve with distraction or tactile stimulation. Suspicion should be raised for seizures when events occur out of deep sleep, there is a loss of consciousness with the event, movements are not suppressible, and there is a period of fatigue afterword (minutes to hours). Further, a past medical history of developmental delay (e.g. autism), developmental regression, or neurologic injury increases patients' risk for seizures.

CONCLUSIONS

Common seizure mimics are highlighted in the age group in which they are most prevalent.

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.

Psychogenic Non-Epileptic Status as Refractory, Generalized Hypertonic Posturing: Report of Two Adolescents

Psychogenic non-epileptic seizures (PNES) or dissociative seizures are found under the umbrella headings of functional/dissociative neurological disorders (FND) in psychiatric classifications (DSM-5; ICD-11). PNES are not characterized by any specific ictal or postictal EEG abnormalities. Patients with PNES can present with motor or non-motor symptoms, frequently associated with a change in the level of consciousness. PNES duration is variable, often longer than that of epileptic seizures. Prolonged PNES, sometimes termed PNES status, involve continuous or repetitive events that exceed 30 min. Prolonged PNES are often misdiagnosed as an epileptic event and are often inappropriately treated with high doses of antiseizure drugs. In this report, we describe two adolescent patients who presented with prolonged PNES characterized by generalized hypertonic posturing and low levels of consciousness. Despite multiple presentation to the Emergency department, and multiple normal video-EEG, the patients were misdiagnosed with epilepsy and were inappropriately treated with antiseizure medications. Both patients presented psychiatric comorbidity, consisting of a major depressive disorder, obsessive-compulsive symptoms, social withdrawal, difficulty of social interaction, and anxious-perfectionist personality traits. The episodes of prolonged PNES gradually declined within 18 months in both patients.

Nonepileptic attack disorder and functional movement disorder: A clinical continuum?

Nonepileptic attack disorder (NEAD) and functional movement disorder (FMD) are functional neurological disorders commonly seen in neuropsychiatry services. Although their initial referral pathways involve epileptologists (NEAD) and specialists in movement disorders (FMD), these conditions are currently classified as two possible manifestations of a single underlying conversion disorder. We set out to compare the characteristics of patients with NEAD and patients with FMD in order to quantify the degree of overlap between these patient groups. We retrospectively reviewed comprehensive clinical data from 146 consecutive patients with functional neurological disorders (NEAD: n = 117; FMD: n = 29) attending a specialist Neuropsychiatry Clinic run by a single Consultant in Behavioral Neurology. The two clinical groups were directly compared with regard to demographic and clinical characteristics, as well as somatic and psychiatric presentations. The results showed that in most features, there were no significant differences between patients with NEAD and patients with FMD. However, patients with NEAD reported an earlier age at onset (p = 0.033) and a higher proportion of acute onset (p = 0.037), alterations of consciousness (p = 0.001), and headache (p = 0.042), whereas patients with FMD reported a higher prevalence of childhood abuse (p = 0.008), as well as mobility problems (p = 0.007) and comorbid functional symptoms (dysarthria, p = 0.004; dizziness, p = 0.035; weakness, p = 0.049). Despite different phenotypic presentations, NEAD and FMD might represent a clinical continuum, with relevant implications in terms of both diagnostic strategies and treatment approaches.

Clinical Classifications of Children With Psychogenic Non-epileptic Seizure

Objective: To analyze the clinical features of children with psychogenic non-epileptic seizures in one tertiary center in China. Methods: Clinical data including medical records and video- electroencephalograph (video-EEG) monitoring records of 88 pediatric PNES patients hospitalized in the pediatric department of Xuanwu Hospital, Beijing, China from April, 2012 to April, 2018 were collected in this study. Demographic information of patients, semiological classification, duration, and frequency of symptoms, risk factors as well as comorbidity were summarized and analyzed. Results: For semiological classification, all PNES related symptoms were divided into different categories: motor symptoms, unresponsiveness, sensory symptoms, visceral symptoms, and abnormal behaviors, among which motor symptoms were the most prevalent form. Risk factors were reviewed and categorized into two groups: persistent factors and predisposing factors, and patients were most frequently affected by the influences of families. The duration and frequency of symptoms varied substantially within PNES patients while the average time of duration was relatively longer than epilepsy as reported previously. Epilepsy was considered as the most frequent comorbidity of PNES and PNES patients misdiagnosed as epilepsy often mistreated with antiseizure medication. Significance: Our study showed that motor PNES are the most frequent seizure type. Family issues were a risk factor for PNES. Epilepsy was the most frequent co-existing neurological comorbidity.

Psychogenic nonepileptic seizures in pediatric population: A review

INTRODUCTION

Psychogenic nonepileptic seizures (PNES) are observable abrupt paroxysmal changes in behavior or consciousness that resemble epileptic seizures, but without concurrent electroencephalographic abnormalities.

METHODS

In this manuscript, we reviewed literature concerning pediatric PNES and focused on those articles published in the last 10 years, in order to try to understand what the state of the art is at the moment, particularly as regards relationship and differential diagnosis with epilepsy.

RESULTS

Psychogenic nonepileptic seizures have been extensively described in literature mainly in adults and less frequently in children. Despite the potential negative impact of a misdiagnosis (unnecessary investigations and antiepileptic drugs, structured pathological behavioral patterns), in literature there is little information regarding the real prevalence, clinical features, treatment, and outcome of PNES in children and adolescents.

CONCLUSION

Psychogenic nonepileptic seizures are common but frequently missed entity in pediatric population. Diagnosis could be difficult, especially in those children who have both epileptic and nonepileptic seizures; video EEG and home video can help clinicians in diagnosis. More studies are needed to better classify PNES in children and facilitate diagnosis and treatment.
