Epilepsy monitoring unit (EMU) admissions are essential for the classification/localization of epileptic seizures (ES) and psychogenic non-epileptic seizures (PNES). However, the duration of admissions is highly variable. Accordingly, we evaluated the duration of 596 EMU admissions and reasons for prolonged (>7 days) lengths of stay (LOS). The average LOS was longer for patients diagnosed with ES (8.0 days, SD 4.1 days) than all others (6.0 days, SD 3.9 days, p<0.001). Of the 596 admissions, 231 (38.8%) had prolonged LOS...

OBJECTIVE: Recent studies have attempted to compare patients affected by psychogenic non-epileptic seizures (PNES) to patients affected by functional motor symptoms (FMS) from a demographic, clinical and psychological perspective. Nevertheless, results are quite controversial and significant conclusions have not been drawn. The aim of our study was to evaluate the phenomenology of psychology of the two groups assessing levels of dissociation and its subcomponents, alexithymia and interoceptive sensitivity in patients with PNES and in patients with FMS...

OBJECTIVE: To compare the performance of 4h-video EEG monitoring (VEEG) and 1h-nap-VEEG in an Epileptology Unit. METHODS: We examined short-term VEEG data from 196 patients admitted to characterize their: (i) clinical events; (ii) epileptic syndromes or (iii) state after status epilepticus or surgery. We compared the 4h-VEEG and 1h-nap-VEEG performances using three measures: (i) the capability to detect epileptic seizures (ES), psychogenic non-epileptic seizures (PNES), interictal epileptiform abnormalities (IEA) and sleep-related IEA; (ii) the usefulness to answer questions on referral; (iii) the sensitivity for the final diagnosis...

Driving restrictions in people with epilepsy (PWE) is a highly contentious topic. The fundamental difficulty lies in achieving a balance between safety and practicality. The aim of this review is to provide an overview, history, and rationale behind current laws regarding driving restriction in PWE. We also discuss recent findings that may be helpful to practitioners during individual discussions with PWE including seizure recurrence risk after first seizure, recurrent seizure, and anticonvulsant with drawl and driving restrictions in patients with psychogenic non-epileptic seizures (PNES)...

PURPOSE: The average delay from first seizure to diagnosis of psychogenic non-epileptic seizures (PNES) is over 7 years. The reason for this delay is not well understood. We hypothesized that a perceived decrease in seizure frequency after starting an anti-seizure medication (ASM) may contribute to longer delays, but the frequency of such a response has not been well established. METHODS: Time from onset to diagnosis, medication history and associated seizure frequency was acquired from the medical records of 297 consecutive patients with PNES diagnosed using video-electroencephalographic monitoring...

PURPOSE: The nature of the symptoms associated with PNES require a multidisciplinary health team. There are too few professionals with an adequate understanding of PNES and therefore many are not able to provide patients with necessary information. In the age of the internet, it is not surprising that patients or caregivers might look for answers online. The purpose of this project was to investigate the online representation of PNES and search frequency for PNES and its associated terms...

PURPOSE: The diagnostic classification of disorders of consciousness is often challenging, particularly the distinction between epileptic and non-epileptic seizures. The aim of the study was to examine serum lactate as a diagnostic marker of transient loss of consciousness. METHOD: Serum lactate levels in blood samples drawn within 2h of the event were compared retrospectively between patients with generalized tonic-clonic seizures (n=195) and patients with other seizures (syncopes [n=52], psychogenic non-epileptic seizures [n=17], and complex focal seizures [n=37]), respectively...

INTRODUCTION: Psychogenic non-epileptic seizures (PNES or "pseudoseizures") remain an obscure topic in the peri-operative setting. They are sudden and time-limited motor and cognitive disturbances, which mimic epileptic seizures, but are psychogenically mediated. Pseudoseizures occur more frequently than epilepsy in the peri-operative setting. Early diagnosis and management may prevent iatrogenic injury. CASE: 48 year-old female with a history of depression and "seizures" presented for gynecologic surgery...

Huntington's disease (HD) is a neurodegenerative condition characterised by motor dysfunction with involuntary movements and loss of voluntary control, cognitive deterioration and psychiatric problems. We report a 51-year-old man with early HD who experienced stereotyped episodes of repetitive, purposeless complex movements and unresponsiveness. His neurological examination was compatible with HD as were all investigations. We diagnosed psychogenic non-epileptic seizures. While seizures are common in juvenile-onset HD, they are no more prevalent in adult-onset HD than in the general population...

The paper presents a case report of seizures in a man of 40 years who was assessed by neurologists and psychiatrists for 15 years. Due to the low efficacy of treatment and permanent health deterioration, the patient was recognized as disabled. Later initial diagnosis of psychogenic non-epileptic seizures was completed by comorbid diagnosis of bipolar affective disorder, type II. Treatment with lamotrigine improved the patient's condition. It has been regarded as a positive effect on organic changes in the brain that are associated with affective and epileptic disorders...

The purpose of this case-matched study was to determine how frequently fibromyalgia is associated with different paroxysmal neurological disorders and explore the utility of fibromyalgia as a predictor for the diagnosis of psychogenic non-epileptic seizures. The billing diagnosis codes of 1,730 new, non-selected patient encounters were reviewed over a three-year period for an epileptologist in a neurology clinic to identify all patients with historical diagnoses of fibromyalgia. The frequency with which epileptic seizures, psychogenic non-epileptic seizures, and physiological non-epileptic events were comorbid with fibromyalgia was assessed...

Muscle activity during seizures is in electroencephalographical (EEG) praxis often considered an irritating artefact. This article discusses ways by surface electromyography (EMG) to turn it into a valuable tool of epileptology. Muscles are in direct synaptic contact with motor neurons. Therefore, EMG signals provide direct information about the electric activity in the motor cortex. Qualitative analysis of EMG has traditionally been a part of the long-term video-EEG recordings. Recent development in quantitative analysis of EMG signals yielded valuable information on the pathomechanisms of convulsive seizures, demonstrating that it was different from maximal voluntary contraction, and different from convulsive psychogenic non-epileptic seizures...

Psychogenic non-epileptic seizures (PNES) are defined as change in behavior or consciousness resembling epileptic seizures but which have a psychological origin. PNES are categorized as a manifestation of dissociative or somatoform (conversion) disorders. Video-EEG recording of an event is the gold standard for diagnosis. PNES represent a symptom, not the underlying disease and the mechanism of dissociation is pivotal in the pathophysiology. Predisposing, precipitating and perpetuating factors should be carefully assessed on a case-by-case basis...

Psychogenic non-epileptic seizures (PNES) are common in neurological settings and often associated with considerable distress and disability. The psychological mechanisms underlying PNES are poorly understood and there is a lack of well-established, evidence-based treatments. This paper advances our understanding of PNES by providing a comprehensive systematic review of the evidence pertaining to the main theoretical models of this phenomenon. Methodological quality appraisal and effect size calculation were conducted on one hundred forty empirical studies on the following aspects of PNES: life adversity, dissociation, anxiety, suggestibility, attentional dysfunction, family/relationship problems, insecure attachment, defence mechanisms, somatization/conversion, coping, emotion regulation, alexithymia, emotional processing, symptom modelling, learning and expectancy...
