We applied conversation analysis in an unselected continuous series of 70 patients to discriminate patients with psychogenic nonepileptic seizures (PNES) from patients with epilepsy. Two psychologists examined the patients' recorded reports. Patients were also submitted to an extensive neuropsychological battery in order to verify whether specific cognitive deficits or mental health problems are typical of patients with PNES and whether some cognitive deficits could prevent the correct diagnosis. The results showed a good percentage of correct diagnosis, with a sensitivity of 0...

Psychogenic non-epileptic seizures (PNES) is a conversion disorder that reflects underlying psychological distress. Female patients with PNES often present with a history of prolonged stressors, especially sexual abuse. In the current study, we studied the relationship between neuropeptide Y (NPY) and PNES symptoms in women with a history of sexual abuse. NPY has been associated with resilience to stress and we hypothesized that low levels would increase the extent and severity of PNES symptoms in this patient population...

PURPOSE: To elucidate the localization of ictal EEG activity, and correlate it to semiological features in self-limited epilepsy with centrotemporal spikes (formerly called "benign epilepsy with centrotemporal spikes"). METHODS: We have performed ictal electric source imaging, and we analysed electroclinical correlations in three patients with self-limited epilepsy with centrotemporal spikes. RESULTS: The source of the evolving rhythmic ictal activity (9...

We hypothesized that (1) the occurrence of psychogenic nonepileptic seizures (PNES) is modulated by the interaction between the 24-hour clock and the sleep-wake cycle and (2) the pattern of modulation in PNES differs from epileptic seizures (ES). We sought to test our hypotheses in a cohort of patients diagnosed with PNES or ES in the setting of an epilepsy monitoring unit (EMU). We retrospectively reviewed consecutive video-EEG (VEEG) recordings of patients who underwent monitoring at the EMU of a tertiary hospital...

Compulsive water drinking or psychogenic polydipsia is now increasingly seen in psychiatric populations. Effects of increased water intake can lead to hyponatremia causing symptoms of nausea, vomiting, seizures, delirium and can even be life threatening if not recognized and managed early. Here we present a 35-year old adult who was diagnosed with psychogenic polydipsia and was successfully managed with a combination of pharmacotherapy, fluid restriction and psychosocial management.

OBJECTIVE: Low-cost evidence-based tools are needed to facilitate the early identification of patients with possible psychogenic nonepileptic seizures (PNES). Prior to accurate diagnosis, patients with PNES do not receive interventions that address the cause of their seizures and therefore incur high medical costs and disability due to an uncontrolled seizure disorder. Both seizures and comorbidities may contribute to this high cost. METHODS: Based on data from 1,365 adult patients with video-electroencephalography-confirmed diagnoses from a single center, we used logistic and Poisson regression to compare the total number of comorbidities, number of medications, and presence of specific comorbidities in five mutually exclusive groups of diagnoses: epileptic seizures (ES) only, PNES only, mixed PNES and ES, physiologic nonepileptic seizurelike events, and inconclusive monitoring...

Whether occurring before or after an epilepsy surgery, psychogenic nonepileptic seizures (PNES) impact treatment options and quality of life of patients with epilepsy. We investigated the frequency of pre- and postsurgical PNES, and the postsurgical Engel and psychiatric outcomes in patients with drug-resistant temporal lobe epilepsy (TLE). We reviewed 278 patients with mean age at surgery of 37.1±12.4years. Postsurgical follow-up information was available in 220 patients, with average follow-up of 4years...

PURPOSE: We compared the semiology of psychogenic nonepileptic seizures (PNES) between patients from the USA and Brazil. This international cross-cultural comparative study may expand understanding of PNES across the borders. METHODS: We retrospectively investigated all patients with PNES admitted to one epilepsy center in the USA and one in Brazil. We classified their seizures into four classes: generalized motor, akinetic, focal motor, and subjective symptoms...

PURPOSE: The aim of the current post hoc study was to investigate factors associated with delay in diagnosis of adult patients with psychogenic nonepileptic seizures (PNES). METHODS: We retrospectively investigated all patients with PNES admitted to the epilepsy-monitoring unit at the Jefferson Comprehensive Epilepsy Center from 2012 through 2016. We identified the median time to diagnosis of PNES and divided the patients into two groups. We studied factors associated with delay in diagnosis of PNES...

True and psychogenic nonepileptic seizures (PNES) go hand in hand. One colors the picture of other. Although it is thought that children carry lower risk for PNES than adults, this may represent the under-diagnosis of this condition in childhood due to few studies on this specific topic. Again, true seizure can be misdiagnosed by dramatic and varied manifestations appearing as psychological phenomena. We report a case of a 9-year-old boy presenting with sudden onset, short lasting, off and on different "melodramatic" episodic behavioral problems with La-Belle' indifference without loss of consciousness, appearing to be of psychogenic origin but finally ended with a diagnosis of temporal lobe epilepsy and responded dramatically with antiepileptics...

REVIEW
S Noachtar, B Güldiken
Non-epileptic paroxysmal disorders may clinically manifest in a similar way to epileptic seizures and have to be considered in the differential diagnosis of epilepsy. Syncope, non-epileptic psychogenic seizures, paroxysmal movement disorders, migraine, transient ischemic attacks and parasomnia constitute the major differential diagnoses. A meticulous history and a third party description are useful for the differential diagnosis. Neurological, psychiatric and cardiological examinations are required for the correct differential diagnosis...

REVIEW
Marco Mcsweeney, Markus Reuber, Liat Levita
Psychogenic Non-epileptic Seizures (PNES) are 'medically unexplained' seizure-like episodes which superficially resemble epileptic seizures but which are not caused by epileptiform discharges in the brain. While many experts see PNES disorder as a multifactorial biopsychosocial condition, little is known about the neurobiological processes which may predispose, precipitate and/or perpetuate PNES symptomology. This systematic meta-review advances our knowledge and understanding of the neurobiological correlates of PNES by providing an up-to-date assessment of neuroimaging studies performed on individuals with PNES...

BACKGROUND: The differential diagnosis of generalized tonic-clonic seizures (GTCS), psychogenic nonepileptic seizures (PNES), and syncope constitutes a major challenge. Misdiagnosis rates up to 20 to 30% are reported in the literature. PURPOSE: To assess the clinical utility of serum lactate levels for differentiation of GTCS, PNES, and syncope based on gender differences. METHODS: Data from 270 patients were evaluated retrospectively. Only patients ≥18 years old with the final diagnosis of GTCS, PNES, or syncope in their chart were recruited...

PURPOSE OF REVIEW: 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. RECENT FINDINGS: Helpful clues can be deduced from history-taking, seizure semiology, ictal/peri-ictal physical exam, and ictal/inter-ictal EEG data...

Psychogenic nonepileptic seizures (PNES) are classified as a mental disorder, the manifestations of which superficially resemble epileptic seizures. There is a notable lack of in-depth qualitative or quantitative studies investigating the stigma attached to PNES. The current study is an exploratory analysis into the nature of perceived stigma in those with PNES when compared with individuals with epilepsy. Individuals with epilepsy (n=78) and PNES (n=47) were recruited from a United Kingdom hospital or membership-led organizations for individuals living with seizures...

OBJECTIVE: This study investigated continuity of neurological care for patients discharged from the epilepsy monitoring unit (EMU) with a diagnosis of psychogenic nonepileptic spells (PNES). Because PNES are seizure-like episodes that cannot be explained by abnormal electrical brain activity, they are challenging for patients to understand and accept. Consequently, after diagnosis, patients commonly fail to start recommended psychotherapy and instead pursue redundant medical care. As consistent relationships with healthcare providers may help, we instituted standard follow-up for patients diagnosed with PNES...

Differentiation between psychogenic nonepileptic seizures (PNES) and generalized convulsive epileptic seizures (ES) is important for appropriate triaging in the emergency department (ED). This can be difficult in the ED, as the event is often not witnessed by a medical professional. In the current study, we investigated whether anion gap (AG), bicarbonate, and the Denver Seizure Score (DSS) could differentiate between PNES and ES. Of a total of 1,354 subjects reviewed from a tertiary care medical center, 27 PNES and 27 ES patients were identified based on clinical description and subsequent electroencephalogram...
