Psychogenic non-epileptic seizures (PNES) are often viewed as manifestations of altered motor and sensory function resulting from psychological responses to adverse experiences. Yet many patients and non-expert healthcare professionals find it difficult to understand how severe disturbances in normal neurological functioning can solely result from underlying psychological mechanisms to the exclusion of other physical causes. Perhaps importantly, recent advances using neuroimaging techniques point to possible structural and functional correlates in PNES...

Psychogenic nonepileptic seizures (PNES) are to be considered in the differential diagnosis of a transient loss of consciousness. Their discrimination from syncope, epileptic seizures or vascular events can be difficult and requires profound knowledge about the semiology and clinical presentation of PNES and their differential diagnoses. Erroneous diagnoses and the resulting therapies lead to elevated morbidity, elevated costs and a poorer outcome. The aim of the present article is to provide an overview on PNES and their delineation from the clinical pictures of epilepsy and syncope...

PURPOSE: To describe the main characteristics of psychogenic nonepileptic seizures (PNES) in adults with epilepsy and intellectual disability (ID), and to analyse the differences regarding psychosocial functioning, epilepsy severity and ID between patients with PNES and a control group without PNES. METHODS: Medical records of adults with ID and epilepsy living at an epilepsy care facility (N = 240) were screened for PNES and evaluated by a neurologist. A control group consisting of patients with epilepsy and ID, without PNES, was matched according to age, sex and level of ID...

PURPOSE: The current study was designed to analyze the clinical spectrum of Psychogenic non-epileptic seizures (PNES) in children. METHODS: Children aged 6-16years with clinically suspected PNES, confirmed by short-term VEEG (STVEEG{video electroencephalogram}) and induction were classified as per Seneviratne classification. Stressors, associated co morbidities, Verbal IQ (Intelligence Quotient) and behavioral abnormalities were assessed using HTP(House tree person) test, DSM IV (Diagnostic and statistical manual of mental disorders) TR criteria, MISIC (Malin intelligence scale for Indian children) and CBCL (Child behaviour checklist)...

Gregg H Rawlings, Markus Reuber
A recent systematic synthesis of qualitative research demonstrated that patients with psychogenic nonepileptic seizures (PNES) often experience unsatisfactory encounters with health care practitioners (HCPs). It is important to understand such interactions from the perspective of those responsible for delivering care. This systematic review aimed to examine the attitudes and perceptions of HCPs toward PNES. A systematic search of 3 databases (Web of Science, PubMed, and CINAHL) was conducted in November 2017...

OBJECTIVES: Psychogenic nonepileptic seizures (PNES) are a manifestation of conversion disorder among children but can be difficult to distinguish from epilepsy. We sought to identify characteristics that differentiate children with PNES from those with epilepsy. METHODS: We conducted a retrospective cohort study of children admitted with epilepsy or PNES to 45 children's hospitals from 2004 to 2014. Children with PNES ( n = 399) versus those with epilepsy ( n = 13 241) were compared on demographic and clinical characteristics, testing, treatment, and health care use...

Psychogenic seizures are often underdiagnosed and epilepsy is very often over-treated which leads to multiple financial, social and stigma related difficulties. The myoclonic seizure itself is a rare phenomenon and when functional movement disorder presents like myoclonus then it's extremely difficult to pinpoint the exact cause. Here, we are presenting a case who was misdiagnosed as having a myoclonic seizure disorder and treated in multiple places without any improvement which ultimately turned out to be functional movement disorder of a rare variety...

Paroxysmal dyskinesias (PD) are hyperkinetic movement disorders where patients usually retain consciousness. Paroxysmal dyskinesias can be kinesigenic (PKD), nonkinesigenic (PNKD), and exercise induced (PED). These are usually differentiated from each other based on their phenotypic and genotypic characteristics. Genetic causes of PD are continuing to be discovered. Genes found to be involved in the pathogenesis of PD include MR-1, PRRT2, SLC2A1, and KCNMA1. The differential diagnosis is broad as PDs can mimic psychogenic events, seizure, or other movement disorders...

Functional neurological symptoms are common in neurology and general medical practice. Functional neurological symptoms refer to neurological symptoms, which are not explained by a defined disease. The most common are functional weakness and non-epileptic seizures. Psychiatric models have dominated the classification, aetiology and treatment, limiting the neurologist's role to making the diagnosis by excluding disease and pronouncing the symptoms to be psychogenic. In this review, we outline the possibility of a positive diagnostic process, which can be the first step of treatment...

OBJECTIVES: We aimed to evaluate whether potential changes in the patient's illness perception can significantly influence short-term seizure burden following video-electroencephalography (EEG) confirmation/explanation of psychogenic nonepileptic seizures (PNES). METHODS: Patients with PNES were dichotomized to two groups based on a five-point Symptom Attribution Scale: (a) those who prior to diagnosis perceived their seizures to be solely ("5") or mainly ("4") physical in origin (physical group) and (b) the remainder of patients with PNES (psychological group)...

PURPOSE: The aim of the current study was to investigate the long-term outcome of patients with psychogenic nonepileptic seizures (PNES) and factors potentially associated with their outcome in Iran. METHODS: We investigated all patients with PNES admitted to the epilepsy monitoring unit at the Shiraz Comprehensive Epilepsy Center from 2008 through 2013. Patients included in this study had a confirmed diagnosis of PNES. In a phone call interview to the patients in December 2017, we obtained the following information: seizure outcome (seizure-free during the past 12 months or not), history of receiving any psychotherapy after confirming their diagnosis in the past, and number of psychotherapy sessions the patient had received...

BACKGROUND: Physicians from various disciplines encounter patients presenting with psychogenic nonepileptic seizures (PNES) as part of their routine clinical practice. Recommendations towards assessing fitness to drive and reporting are clearer for conditions such as neurocognitive disorders and epilepsy, but such guidelines do not exist for patients with PNES. Here, we assess physicians' attitudes towards driving for patients diagnosed with PNES. METHODS: Electronic questionnaires were sent to Neurology and Family Medicine physicians practicing at Creighton University Medical Center and Psychiatry physicians practicing at Creighton-Nebraska Psychiatry Residency Program to assess their opinion regarding driving risk when encountering PNES...

REVIEW
Stoyan Popkirov, Alan J Carson, Jon Stone
A history of head injury is common in patients with psychogenic nonepileptic seizures (PNES). This association has so far been interpreted as either spurious or psychologically mediated. Biased recall and misattribution could foster illness beliefs about brain damage that promote symptom production. Furthermore, the emotional impact of head injury could induce long-term changes in stress responsivity. Lastly, maladaptive cognitive-behavioural processes involving symptom modelling and aversive conditioning, known to play a role in functional neurological disorders, could contribute to the development of PNES after head trauma...

The association between emotional stimuli and temporal lobe epilepsy (TLE) is largely unknown. Here, we report the case of a depressed, 50-year-old female complaining of episodes of a "spaced out" experience precipitated by emotional stimuli. Psychogenic non-epileptic attacks were suspected. However, video-EEG coupled with emotional stimuli-provoked procedures and MRI findings of amygdala enlargement, led to the diagnosis of left TLE. Accurate diagnosis and explanation improved her subjective depression and seizure frequency...

PURPOSE: Information about existing healthcare resources for the management of seizures in developing countries is lacking. These countries are often poorly equipped to deal with the immense burden of costs, mortality, stigma, seizure-related disability, and comorbidities presented by seizure disorders. This study aimed to contribute to the goals of the International League Against Epilepsy (ILAE) by investigating the resources available for patients with seizure in Namibia. METHODS: Two separate surveys on the diagnostic and treatment practices for epileptic seizures (ES) and psychogenic nonepileptic seizures (PNES) were administered to private healthcare practitioners (HCPs) in Namibia...

PURPOSE: Psychogenic nonepileptic seizures (PNES) are paroxysmal episodes superficially resembling epileptic seizures but are not associated with any electrical abnormalities. Despite the existence of recent evidence addressing psychological interventions on PNES, there is a scarcity of studies investigating such interventions on patients with dual diagnoses, such as in temporal lobe epilepsy/mesial temporal sclerosis (TLE-MTS) with comorbid PNES; TLE-MTS is a very frequent epilepsy syndrome found in tertiary centers...

Objective: Functional neurological disorders (FNDs) and psychogenic nonepileptic seizures (PNES) are likely as common in Sub-Saharan Africa (SSA) as in the rest of the world, but there is a dearth of literature on the epidemiology and clinical presentation of these disorders in Africa. The purpose of this paper is to describe a case series of FNDs presenting to a referral hospital in SSA. In addition, we review the existing literature on FNDs in Africa. Methods: A hospital-based retrospective cross-sectional study was conducted to determine the prevalence, epidemiology, and clinical phenotype of FNDs and PNES in a referral hospital in Northern Tanzania over a 6-year period (2007-2013)...

Epilepsy and psychogenic nonepileptic seizures (PNES) can coexist and may present in two forms: sequential and simultaneous. In sequential presentations, epileptic seizures (ES) are treated and PNES emerge later. Simultaneous recording of ES and PNES by video-electroencephalogram (vEEG) is less well described. We retrospectively reviewed all patients diagnosed with PNES by vEEG following standard seizure induction practices over a 21-month period. Within this cohort, we established the prevalence of coexisting epilepsy using clinical and electrographic data acquired from our epilepsy-specific patient record...

An 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...
