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.

Unmasking the masquerade: the diagnosis and management of psychogenic nonepileptic seizures.

The diagnosis and management of psychogenic non-epileptic seizures (PNES) is often challenging. This literature review was done to investigate available data on PNES to make recommendations for its management. To research relevant data on the diagnosis and challenges in the management of PNES. The methodology involved a systematic review of relevant studies and review articles by leading authorities in PNES, using the databases of MEDLINE, ScienceDirect, Cochrane, and PubMed. Out of an eventual 211 screened, 15 were selected based on exclusion and inclusion criteria. Concepts such as 'psychogenic nonepileptic seizures, diagnosis, and management' were searched with the key term, 'PNES'. An analysis of 15 articles was undertaken, and the focus was mainly on the diagnostic criterion and the management approaches adopted in the different studies. The results indicated that many of the studies consistently required video EEG (vEEG) as confirmatory tests for the establishment of PNES, in keeping with the staged approach to diagnosis set by the Nonepileptic Seizure Task Force of Epilepsy. Recent studies emphasised early communication and healthy rapport between patients and providers of care in conveying a diagnosis. Pilot studies on the pharmacological and psychological treatments for PNES were promising. The unmasking of the masquerade of PNES is challenging for clinicians in primary and tertiary care. Raising awareness of the condition reduces the burden on health care. Definitive guidelines and more control trials are required. Provocative measures to establish the diagnosis are limited. The feasibility of using the tilt table as a provocative measure is discussed.

Child Neurology Residency Survey of Psychogenic Nonepileptic Seizure Education (P2-2.004)

<h3>Objective:</h3> To assess the learning needs of pediatric neurology resident trainees and program directors (PD) on the education of psychogenic nonepileptic seizures (PNES) during training. <h3>Background:</h3> PNES proves difficult to differentiate from epileptic seizures (ES) even for neurologists who see these conditions frequently, given overlapping semiologic findings between the two diagnoses. Previous studies have shown trainees, including neurology trainees, are not very accurate in differentiating PNES from ES. Neurologists often find the communication of PNES difficult. Despite these challenges, most programs do not have a formal curriculum for teaching PNES and there are no ABPN standards for residency curricula in this topic. <h3>Design/Methods:</h3> Two unique surveys were designed, one for child neurology trainees and one for PDs. Questions were designed to assess trainees’ abilities, current education received, and desired teaching. Similarly, PDs’ level of confidence in trainee management of PNES was assessed, as well as specific preferences for a standardized curriculum. <h3>Results:</h3> Sixty-five trainees out of approximately 202 and 21 PDs and associate PDs have responded to the survey. About one-third of trainees report neutral to low levels of confidence and 36.9% report neutral to low levels of knowledge in caring for PNES patients. Trainees reported that directing PNES patients to appropriate management was the most challenging aspect of care, followed by communicating the diagnosis, with 60.0% and 46.1% reporting difficulty, respectively. Trainees report preferring to learn about this topic through reading material and simulation. One-fifth of PDs feel their current PNES education is not sufficient and 52.4% of PDs would incorporate a standardized curriculum, with remaining PDs reporting willingness depending on the required time. <h3>Conclusions:</h3> Areas of needed training and desired teaching format were identified based on trainee responses. PDs desire a standardized curriculum and would incorporate one into their programs. Findings of this study will be utilized to create a national curriculum. <b>Disclosure:</b> The institution of Dr. Albert has received research support from Nationwide Children’s Hospital, Division of Neurology, Internal Research Grant.

Interobserver reliability of a recently proposed semiological classification in psychogenic nonepileptic seizures in children

BackgroundThe aim of this study is to examine the semiological features of Psychogenic Nonepileptic Seizures (PNES) in children and to evaluate interobserver reliability (IR) of two different classifications. to identify the sources of any variance in agreement and to estimate the IR of the classification systems MethodsSemiological features of 137 pediatric patients with PNES with and without epilepsy were analyzed. Two different, blinded observers evaluated these semiological features according to A. Asadi-Pooya and Seneviratne et al. classifications. The interobserver reliability was measured using a kappa (κ) coefficient for each PNES classification. ResultsThe mean age of patients with PNES was 14.3 (SD: 2.9) years. Ninety five patients were female (69.3 %), 42 were male (30.6 %). Ictal eye closure (n:109, 79.5 %), was the most common seizure semiology. Asymmetric limb movements (n: 71, 51.8 %), motor phenomenon lasting> two minutes (n:69, 50.3 %), and closed mouth (n:53, 38.6 %) were other common seizure semiologies of PNES. Kappa value was higher in A. Asadi-Pooya classification than Seneviratne classification (k = 0.697 and k = 0.433; p < 0.05). Kappa values were higher in the motor and non-motor categories of A. Asadi-Pooya classification than in the mixed category (k = 0.713, k = 0.799 and k = 0.455; p < 0.05). ConclusionThe added value of the new classification scheme with respect to uniform application by experienced pediatric neurologists seems to be reliable and influential, as interobserver reliability of the new classification system was higher than the early classification. Our findings suggest that a simple but comprehensive classification would be useful in the management of PNES.

Psychogenic non-epileptic seizures: Chronology of multidisciplinary team approach to diagnosis and management

While the diagnosis and management of psychogenic non-epileptic seizures (PNES) remain challenging, certain evidence-based guidelines exist, which can help to optimize patient care. A multidisciplinary team approach appears to have many benefits. Current recommendations exist for some aspects of diagnosis and management of PNES, including levels of diagnostic certainty as proposed by the International League Against Epilepsy's expert Task Force on PNES. Other aspects of clinical still care lack clear consensus, including use of suggestion techniques for recording PNES and optimal terminology, since the term “functional seizures” has recently been proposed as a possible term to replace “PNES”. The present article aims to (1) review current recommendations and (2) discuss our own team's experience in managing patients with PNES. This is organized chronologically in terms of the roles of the neurologist, psychiatrist and psychologist, and discusses diagnostic issues, psychiatric assessment and treatment, and psychotherapeutic approaches.

Psychogenic Nonepileptic Seizures and Psychosocial Management: A Narrative Review.

Psychogenic non-epileptic seizure (PNES) is a common disorder that imitates epileptic seizures and has its etiological roots in psychological distress. Due to its “epileptic” similarity, it is often dealt with not only by mental health professionals but also by physicians, pediatricians and neurologists. There is a growing consensus towards the psychotherapeutic treatment of the disorder, albeit a lack of clarity in choosing a gold-standard approach. This paper seeks to serve as a compendium of different psychotherapeutic approaches and their efficacy in the management of PNES. The paper employed the search strategy by selecting the keywords: “Psychogenic Non-Epileptic Seizures (PNES) and psychosocial management”, “PNES Treatment approach”, “PNES and psychotherapy” in PUBMED, EBSCO host, PsycINFO, and SCOPUS database. Eventually, specific therapies were cross-searched with PNES for an exhaustive review. Several studies were found employing various psychotherapeutic approaches for the treatment of PNES in pilot studies, randomized controlled, or open uncontrolled trials. Cognitive Behavior Therapy was demonstrated as an efficacious treatment for PNES in a randomized controlled trial (RCT). Other approaches that were effective in ameliorating the symptoms were psychodynamic therapies or psychoeducation based group therapies. Some therapies like Novel Integrative psychotherapy, Eye Movement Desensitisation Therapy and Mindfulness-based therapies require further exploration in larger clinical trials. The findings demonstrate that psychological intervention for PNES is a promising alternative treatment approach with a need for more RCTs with a larger sample and robust methodology for better generalization.

A COMPARITIVE STUDY OF PSYCHAITRIC DISORDERS AMONG PATIENTS WITH EPILEPTIC SEIZURES WITH VERSUS WITHOUT PSYCHOGENIC NON EPILPETIC SEIZURES

The International League Against Epilepsy defines psychogenic nonepileptic seizures (PNESs) as attacks that superficially mimic epileptic seizures but without any electrophysiological evidence of abnormal neuronal activity(1). PNESs are considered Experiential and behavioral responses to triggers , either external or internal , that resembles epileptic seizures but are neither associated with epileptic discharges in the electroencephalogram (EEG) nor other readily identifiable pathophysiological changes(2). PNES does not finds home either in psychology or in medical settings because of its pseudo neurological and psychological features, and thus, management of PNES, remains a challenge because it involves combined effort of psychologist, psychiatrist, and neurologist(3)The epidemiology of dual diagnosis of epilepsy and PNES is considerably uncertain ; actively comorbid epilepsy has been reported in 6%to 60% of patients with PNES.(4,5)Patients with PNES were found to have high rates of comorbid psychiatric disorders, with nearly all patients with PNES having at least one current additional psychiatric disorder. The comorbidities may act as precipitator or triggers of PNES or may coexist without such a direct relation.(4)For an accurate diagnosis to be reached both , meticulous history taking with episodes semiology coherent with the characteristic features of PNES, and video-EEG recording lacks epileptiform activity in all the stages (i.e., immediately before, during or after the ictal event) are required.

Neurology specialists’ visual interpretation of psychogenic nonepileptic seizures: Contemplating their etiology and existing challenges

PurposeThe purpose of this study was to explore how neurology specialists with interest in epilepsy depict psychogenic nonepileptic seizures (PNES) and their experience of diagnosing and treating the disorder. MethodsAn art project was organized as part of the curriculum of the 14th Latin American Summer School on Epilepsy (LASSE) in São Paulo (Brazil) from February 27th to March 6th, 2020. Willing neurologists were invited to draw or paint PNES and present their professional perspective of this disorder. Grouped by common themes, the artworks were analyzed in the context of the existing literature on PNES. ResultsThe participants created 31 paintings and drawings, 13 of which were selected to represent the recurring themes. Throughout the artworks, neurologists often portrayed PNES as masking the underlying psychological issues, but there was little emphasis on the genesis of PNES itself. The manifestation of PNES was more attributed to just emotional suppression rather than to the influence of different situational factors on a pre-established seizure scaffold. Considering the management of PNES, neurology specialists used the symbol of a labyrinth to represent the difficulties of effectively providing diagnosis and multidisciplinary care for the patients. The general outlook on PNES was associated with darkness, possibly due to limited understanding of the disorder’s nature and the unavailability of effective treatment options. ConclusionOur study shows that art projects can be useful to better grasp neurology specialists’ opinions about a certain disorder. Further research is needed to elucidate the mechanisms of PNES and help establish multidisciplinary care.

A South African review of routinely-collected health data of psychogenic nonepileptic seizure patients referred to psychiatrists in Johannesburg

Patients with psychogenic nonepileptic seizures (PNES) are often referred to psychiatrists for treatment of functional neurological symptom disorder (FNSD). However, not all patients with FNSD have an identified psychiatric comorbidity [1].The aim of this observational study was to characterize the clinical and psychiatric features of patients with PNES from Johannesburg, South Africa, where a high frequency of PNES has been reported [2], and compare these findings to other reports. We hypothesized that patient outcomes regarding treatment adherence and episode frequency would improve when treated within a closed multidisciplinary team. The data included a retrospective record review of patients diagnosed with PNES from an epilepsy monitoring unit and referred for psychiatric assessment and treatment between November 2013 and July 2017.Fifty-nine cases met the criteria for the study. There were 7 male and 52 female participants, aged between 14 and 72 years (M = 33.76, SD = 13.88). The most frequently reported comorbid symptoms were anxiety (90%); dissociative symptoms (51%); headaches (76%) and gastrointestinal symptoms (36%). Important patient characteristics included past substance abuse (76%); impaired attachment (86%); past trauma (69%) and sexual trauma (29%). Generalized anxiety disorder (76%), major depressive disorder (64%) and PTSD (22%) were the most prevalent psychiatric diagnoses. After receiving psychiatric treatment, 47% of patients experienced a decrease in the frequency of episodes, while 86% became aware of the precipitants of their episodes.Psychiatric data can valuably inform current theories of PNES management. This study contributes to the understanding of comorbid, aetiological, and prognostic factors that are crucial to refining coherent models that will guide practice.

Psychogenic Non-epileptic Seizures and Pseudo-Refractory Epilepsy, a Management Challenge.

Psychogenic nonepileptic seizures (PNES) are neurobehavioral conditions positioned in a gray zone, not infrequently a no-man land, that lies in the intersection between Neurology and Psychiatry. According to the DSM 5, PNES are a subgroup of conversion disorders (CD), while the ICD 10 classifies PNES as dissociative disorders. The incidence of PNES is estimated to be in the range of 1.4–4.9/100,000/year, and the prevalence range is between 2 and 33 per 100,000. The International League Against Epilepsy (ILAE) has identified PNES as one of the 10 most critical neuropsychiatric conditions associated with epilepsy. Comorbidity between epilepsy and PNES, a condition leading to “dual diagnosis,” is a serious diagnostic and therapeutic challenge for clinicians. The lack of prompt identification of PNES in epileptic patients can lead to potentially harmful increases in the dosage of anti-seizure drugs (ASD) as well as erroneous diagnoses of refractory epilepsy. Hence, pseudo-refractory epilepsy is the other critical side of the PNES coin as one out of four to five patients admitted to video-EEG monitoring units with a diagnosis of pharmaco-resistant epilepsy is later found to suffer from non-epileptic events. The majority of these events are of psychogenic origin. Thus, the diagnostic differentiation between pseudo and true refractory epilepsy is essential to prevent actions that lead to unnecessary treatments and ASD-related side effects as well as produce a negative impact on the patient's quality of life. In this article, we review and discuss recent evidence related to the neurobiology of PNES. We also provide an overview of the classifications and diagnostic steps that are employed in PNES management and dwell on the concept of pseudo-resistant epilepsy.

An Overview of Psychogenic Non-Epileptic Seizures: Etiology, Diagnosis and Management.

The purpose of this review is to provide an update of the research regarding the etiology, diagnosis and management of psychogenic non-epileptic seizures (PNES). A literature search using Pubmed, Ovid MEDLINE and EMBASE database was performed from 2000 up to August 2017. We have evaluated the different factors leading to PNES as well as the diagnostic approach and management of this disorder which continue to be very difficult. The coexistence of epilepsy and PNES poses special challenges and requires the coordinated efforts of the family physicians, psychiatrists, psychologists and neurologists. Although this condition has an overall poor prognosis, a multidisciplinary approach in the diagnosis and management of this disorder would likely improve the outcomes. We have proposed a diagnostic and treatment algorithm for PNES and suggested a national registry of patients suffering from this condition. The registry would contain data regarding treatment and outcomes to aid in the understanding of this entity.

5.2 Ethical Dilemmas: What Connects Whole Genome Sequencing, Management of Psychogenic Nonepileptic Seizures, and Psychiatrists' Use of Social Media?

The goal of this session is to review articles selected by AACAP's Lifelong Learning Committee that share a common focus on current ethical issues, principles, and policy implications while addressing different topics, including clinical practice, research, social media, and the 2014 AACAP Code of Ethics. Articles include ethical issues relevant to 1) the reporting of results of whole-genome sequencing (WGS) as a genetic test for autism spectrum disorder (ASD) to patients and families and the use of clinically obtained WGS for future research; 2) the diagnosis and management of psychogenic nonepileptic seizures; 3) psychiatrists interacting with the media; and 4) key changes in the 2014 AACAP Code of Ethics.

Psychogenic Non-Epileptic Seizures.

In this review, we elucidate the evaluation process involved in the diagnosis of psychogenic non-epileptic seizures (PNES). Minimum clinical criteria required to attain this diagnosis via a staged approach are delineated. The psychological underpinnings and management of PNES from the neurologists' perspective are also explored. Helpful clues can be deduced from history-taking, seizure semiology, ictal/peri-ictal physical exam, and ictal/inter-ictal EEG data. No single clinical data point is definitively diagnostic of PNES. Instead, the level of certainty for PNES diagnosis is contingent upon concordance of the composite clinical evidence available. Robust neurologist-patient alliance not only facilitates the evaluation process but can influence therapeutic impact. While diagnosis of PNES can be challenging, this diagnosis can be reliably made upon establishing concordance of the historical, physical exam, and video-EEG findings. Evidence-based treatments are available for patients with PNES. Continued efforts remain necessary to enhance timely diagnosis and interdisciplinary management for patients with PNES.

PNES around the world: Where we are now and how we can close the diagnosis and treatment gaps-an ILAE PNES Task Force report.

SummaryAn international consensus clinical practice statement issued in 2011 ranked psychogenic nonepileptic seizures (PNES) among the top three neuropsychiatric problems. An ILAE PNES Task Force was founded and initially charged with summarizing the current state of the art in terms of diagnosis and treatment, resulting in two publications. The first described different levels of diagnostic certainty. The second summarized current knowledge of management approaches. The present paper summarizes an international workshop of the ILAE PNES Task Force that focused on the current understanding and management of PNES around the world. We initially provide a knowledge update about the etiology, epidemiology, and prognosis of PNES—in adults and in special patient groups, such as children, older adults, and those with intellectual disability. We then explore clinical management pathways and obstacles to optimal care for this disorder around the world by focusing on a number of countries with different cultural backgrounds and at very different stages of social and economic development (United Kingdom, U.S.A., Zambia, Georgia, China, and Japan). Although evidence‐based methods for the diagnosis and treatment of PNES have now been described, and much is known about the biopsychosocial underpinnings of this disorder, this paper describes gaps in care (not only in less developed countries) that result in patients with PNES not having adequate access to healthcare provisions. A range of challenges requiring solutions tailored to different healthcare systems emerges. Continued attention to PNES by the ILAE and other national and international neurologic, psychiatric, and health organizations, along with ongoing international collaboration, should ensure that patients with PNES do not lose out as healthcare services evolve around the world.

Psychological interventions for psychogenic non-epileptic seizures: A meta-analysis

PurposeThe aim of this meta-analysis is to evaluate and synthesize the available evidence from the previous 20 years regarding the utility of psychological interventions in the management of psychogenic non-epileptic seizures (PNES). MethodStudies were retrieved from MEDLINE via OvidSP and PsychINFO. Selection criteria included controlled and before-after non-controlled studies including case series, using seizure frequency as an outcome measurement. Studies were required to assess one or more types of psychological intervention for the treatment of PNES in adults. Data from 13 eligible studies was pooled to examine the effectiveness of psychological interventions in treating PNES on two primary outcomes: seizure reduction of 50% or more and seizure freedom. A meta-analysis was conducted with data extracted from 228 participants with PNES. ResultsInterventions reviewed in the analysis included CBT, psychodynamic therapy, paradoxical intention therapy, mindfulness and psychoeducation and eclectic interventions. Meta-analysis synthesized data from 13 studies with a total of 228 participants with PNES, of varied gender and age. Results showed 47% of people with PNES are seizure free upon completion of a psychological intervention. Additional meta-analysis synthesized data from 10 studies with a total of 137 participants with PNES. This analysis found 82% of people with PNES who complete psychological treatment experience a reduction in seizures of at least 50%. ConclusionThe studies identified for this analysis were diverse in nature and quality. The findings highlight the potential for psychological interventions as a favorable alternative to the current lack of treatment options offered to people with PNES.

Communicating diagnostic certainty of psychogenic nonepileptic seizures - a national study of provider documentation.

Management of psychogenic nonepileptic seizures (PNES) requires collaboration among and between health care professionals. Although criteria are established for diagnosis of PNES, miscommunication between neurologists, primary care providers, and mental health professionals may occur if the clinical impression is not clearly articulated. We extracted progress notes from the Department of Veterans Affairs (VA) electronic health record (EHR) nationally to study veterans who were evaluated for PNES. Of the 750 patients being worked up for PNES, the majority of patients did not meet criteria for PNES (64.6%). Of those who were thought to suffer from PNES, 147 (19.6%) met International League Against Epilepsy (ILAE) criteria for documented PNES, 14 (1.9%) for clinically established PNES, and 104 (13.9%) for probable or possible PNES. Neurologists tended to use ambiguous language, such as "thought to be" or "suggestive of" to describe their impressions of patients overall, even those with definitive PNES. Ambiguous language may lead to miscommunication across providers and inappropriate health care.

Bridging a clinical gap in psychogenic nonepileptic seizures: Mental health provider preferences of biopsychosocial assessment approaches.

Management of psychogenic nonepileptic seizures (PNES) is complex, requiring multidisciplinary care. A standardized assessment and formulation approach to PNES is lacking, yet use of a comprehensive model may alleviate problems such as mental health aftercare noncompliance. Although a biopsychosocial (BPS) approach to PNES balancing predisposing, precipitating, and perpetuating (PPP) variables has been described and has been recently tested in pilot form, it is unclear how this assessment style is perceived among community mental health practitioners such as psychotherapists (including psychologists, counselors, and social workers). We predicted preference of a comprehensive "BPS/PPP" assessment style by those most involved in PNES care (i.e., community psychotherapists). One hundred and forty-three community-based social workers and counselors completed a survey featuring a fictional PNES case followed by assessment style options ("Multiaxial," "Narrative," and "BPS/PPP"). Respondents clearly preferred the robust BPS/PPP approach over less-comprehensive multiaxial and narrative assessments (p<0.0001). Reasons for choosing the BPS/PPP by respondents include ease of organization, clear therapeutic goals, and comprehensive nature. This assessment of acceptability of a BPS/PPP approach to PNES assessment among community mental health practitioners may provide a patient-centered mechanism to enhance referrals from the neurological to mental health setting. Implications and future directions are explored.

A standardized diagnostic approach and ongoing feedback improves outcome in psychogenic nonepileptic seizures.

Psychogenic nonepileptic seizures (PNES) are episodic alterations in behavior presumed to reflect a physical manifestation of underlying psychological distress. Standardized treatment approaches for PNES care are lacking. We evaluated common approaches to PNES management that do not require significant commitment of time and resources. Patients with PNES established with video-EEG monitoring were randomized to one of the following three groups: 1) PNES diagnosis delivered per the discretion of the attending physician with advice to seek mental health assistance in the community (n=12), 2) scripted PNES diagnosis provided and inpatient psychiatry consult obtained (n=10), and 3) weekly follow-up phone calls made in addition to scripted diagnosis and inpatient psychiatry consultation (n=15). Reduction in event frequency measured at 8weeks following hospital discharge represented the primary outcome variable. Secondary variables analyzed included exploration of change in self-reported mood, quality of life, and healthcare utilization. No significant improvements were noted in patients simply given a PNES diagnosis and advised to seek outside care on any measure. In contrast, patients receiving a scripted diagnosis and psychiatric consultation demonstrated decreased PNES frequency accompanied by improved quality of life (QOL). Patients also receiving weekly phone calls not only demonstrated decreased PNES frequency and improvements in QOL but also exhibited improved mood. These findings demonstrate that providing diagnostic information regarding PNES is insufficient by itself to meaningfully affect patient outcome. Structured feedback and psychiatric consultation appeared adequate to significantly reduce PNES frequency and improve aspects of quality of life, while the addition of a weekly phone contact also led to improved mood.

Diagnostic assessment and case formulation in psychogenic nonepileptic seizures: A pilot comparison of approaches

Management of psychogenic nonepileptic seizures (PNES) is complex, requiring multidisciplinary care. A standardized assessment approach to PNES is lacking, yet use of a comprehensive model may alleviate problems such as mental health aftercare noncompliance. Although a biopsychosocial (BPS) approach to PNES balancing predisposing, precipitating, and perpetuating (PPP) variables has been described, it is unclear how this formulation style is perceived amongst clinicians. We predicted preference of a comprehensive, “BPS/PPP” assessment style by those most involved in PNES diagnosis and care (i.e., neurologists and psychologists). Sixty epileptologists, psychiatrists, and psychologists completed a survey featuring a fictional PNES case followed by assessment style options (“Multiaxial,” “Narrative,” and “BPS/PPP”). Epileptologists and psychologists (“nonpsychiatrists”) differed from psychiatrists in PNES case formulation choice, with nonpsychiatrists preferring the robust BPS/PPP approach and with psychiatrists opting for less comprehensive Multiaxial and Narrative assessments (p=0.0009). Reasons for choosing the BPS/PPP by nonpsychiatrists included ease of organization, clear therapeutic goals, and comprehensive nature. Alternatively, psychiatrists cited time constraints and familiarity as reasons to prefer briefer Multiaxial or Narrative approaches. This pilot assessment of acceptability of a BPS/PPP approach to PNES case formulation, thus, reveals important gaps in formulation priorities between neurologists and psychiatrists. Implications and future directions are explored.
