Pharyngeal dysesthesias as aura in epilepsy localized to the non-dominant frontal operculum misdiagnosed as non-epileptic seizures.

Neurocase 2020 Jul 2:1-4. Epub 2020 Jul 2.

Department of Neurology, University of South Alabama Medical Center , Mobile, AL, USA.

The diagnosis of atypical paroxysmal events represents a significant challenge for clinicians when differentiating epileptic from nonepileptic events. The ictal manifestations of pharyngeal dysesthesias are often misdiagnosed and difficult to distinguish clinically, given their subtle features such as pharyngeal discomfort with and without autonomic symptomology. We report a rare case of isolated ictal pharyngeal dysesthesias localizing to the non-dominant frontal operculum lobe misdiagnosed as psychogenic and later confirmed by continuous video-EEG monitoring.

Arch Acad Emerg Med 2020 20;8(1):e10. Epub 2020 Jan 20.

Department of laboratory science,chalous branch,islamic azad iniversity,chalous,iran.

Psychogenic non-epileptic seizures (PNES) are paroxysmal changes that mimic epileptic seizures, so often misdiagnosed and treated for epilepsy. PNES are considered a psychiatric illness, personality pathology, and experiential and behavioral manifestation of depression. Despite studies over the past two decades, the pathological mechanisms of this disorder are unclear. Read More

Differentiating PNES from epileptic seizures using conversational analysis on French patients: A prospective blinded study.

Epilepsy Behav 2020 Jun 26;111:107239. Epub 2020 Jun 26.

Department of Neurology, University Hospital of Tours, France.

Psychogenic nonepileptic seizures (PNES) resemble epileptic seizures (ES) but are not caused by the occurrence of excessive cortical neuronal discharge. Previous studies in German-, English-, and Italian-speaking patients showed that patients used a different communicative style to talk about their seizures. They demonstrated that the diagnosis between PNES and ES could be predicted using qualitative assessment and a diagnostic scoring aid (DSA). Read More

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

Front Neurol 2020 2;11:461. Epub 2020 Jun 2.

Department of Neuroscience, Imaging and Clinical Science, "G. D'Annunzio" University of Chieti-Pescara, Chieti, Italy.

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.

An investigation into the preferred terminology for functional seizures.

Epilepsy Behav 2020 Jun 11;111:107183. Epub 2020 Jun 11.

Neuropsychiatry Service, St. George's Hospital, Blackshaw Road, London SW17 0QT, United Kingdom of Great Britain and Northern Ireland.

There is considerable debate in the literature regarding what to call functional seizures, with terms such as pseudoseizures, nonepileptic attack disorder (NEAD), and dissociative seizures being used. Provision of an accurate diagnosis and coherent explanation is a vital first step in the management of functional seizures and can result in cessation or reduced frequency for some individuals. This study investigated preferences for and offensiveness of terms used to describe functional seizures, and expectations for recovery with psychological treatment. Read More

Psychogenic nonepileptic (functional) seizures: Significance of family history and model learning.

Psychiatry Res 2020 May 31;290:113166. Epub 2020 May 31.

Epilepsy Research Center, Shiraz University of Medical Sciences, Shiraz, Iran. Electronic address:

Purpose: If a positive family history of seizures plays a significant role that contributes to the risk for developing psychogenic nonepileptic seizures (PNES) by means of model learning, one would expect that patients with PNES with a family history of seizures show a different semiology than those without such a history. We investigated whether the above hypothesis is valid.

Methods: In this retrospective study, all patients with PNES, who were diagnosed at Shiraz Comprehensive Epilepsy Center at Shiraz University of Medical Sciences, Iran, from 2008 until 2019, were investigated. Read More

Trait and state interoceptive abnormalities are associated with dissociation and seizure frequency in patients with functional seizures.

Epilepsia 2020 Jun 5;61(6):1156-1165. Epub 2020 Jun 5.

Neurosciences Research Centre, St George's University of London, London, UK.

Objective: Dissociative traits represent a disturbance in selfhood that may predispose to, and trigger, functional seizures (FSs). The predictive representation and control of the internal physiological state of the body (interoception) are proposed to underpin the integrity of the sense of self ("minimal selfhood"). Therefore, discrepancies between objective and subjective aspects of interoception may relate to symptom expression in patients with FSs. Read More

EEG-based classification of epilepsy and PNES: EEG microstate and functional brain network features.

Brain Inform 2020 May 29;7(1). Epub 2020 May 29.

Department of Mathematics and Computer Science, Eindhoven University of Technology, TU/e, P.O.Box: 513, 5600MB, Eindhoven, NL, The Netherlands.

Epilepsy and psychogenic non-epileptic seizures (PNES) often show over-lap in symptoms, especially at an early disease stage. During a PNES, the electrical activity of the brain remains normal but in case of an epileptic seizure the brain will show epileptiform discharges on the electroencephalogram (EEG). In many cases an accurate diagnosis can only be achieved after a long-term video monitoring combined with EEG recording which is quite expensive and time-consuming. Read More

Self-Report questionnaires for the diagnosis of psychogenic non-epileptic seizures in clinical practice. A comprehensive review of the available instruments.

Seizure 2020 Jul 26;79:30-43. Epub 2020 Apr 26.

Laboratory of Neurological Disorders, Istituto di Ricerche Farmacologiche Mario Negri IRCCS, Milano, Italy.

We searched Medline from 1946 to 2019 for reports exploring differences between PNES and other comparable paroxysmal events using clinical instruments, few of which focused on the differential diagnosis using broad-based questionnaires covering multiple aspects of this condition. The majority investigated single items to highlight specific differences, either qualitative or quantitative, between groups and to elucidate some of the pathogenetic mechanisms of PNES. We selected all variables that proved to be useful for differentiating PNES from other types of paroxysmal events and classified them by category, by instrument utilized and method of investigation.

Management of functional neurological disorder.

J Neurol 2020 Jul 19;267(7):2164-2172. Epub 2020 Mar 19.

Neuroscience Research Centre, Institute of Molecular and Clinical Sciences, St. George's University of London, Cranmer Terrace, London, SW17 0RE, UK.

Functional neurological disorder (FND) is a common cause of persistent and disabling neurological symptoms. These symptoms are varied and include abnormal control of movement, episodes of altered awareness resembling epileptic seizures and abnormal sensation and are often comorbid with chronic pain, fatigue and cognitive symptoms. There is increasing evidence for the role of neurologists in both the assessment and management of FND. Read More

Peri-ictal responsiveness to the social environment is greater in psychogenic nonepileptic than epileptic seizures.

Epilepsia 2020 Apr 10;61(4):758-765. Epub 2020 Mar 10.

Sheffield Teaching Hospitals National Health Service Foundation Trust, Royal Hallamshire Hospital, Sheffield, UK.

Objective: To look for evidence of peri-ictal social interaction in psychogenic nonepileptic seizures (PNES) and epileptic seizures exploring the notion of PNES as a form of nonverbal communication.

Methods: Video recordings of typical seizures experienced by patients with epilepsy and PNES were obtained in a naturalistic social setting (residential epilepsy monitoring unit). Video analysis by three nonexpert clinicians identified 18 predefined semiological and interactional features indicative of apparent impairment of consciousness or of peri-ictal responsiveness to the social environment with assessment of interrater reliability using Fleiss κ.

Psychosocial and Physiologic Characteristics of Patients with Non-epileptic Events: A Retrospective Study.

Cureus 2020 Jan 24;12(1):e6767. Epub 2020 Jan 24.

Neurology, Marshall University School of Medicine, Huntington, USA.

Background The main focus of this study is to aid early identification of psychogenic non-epileptic seizure (PNES) patients by identifying physical and psychosocial characteristics to reduce the health care burden, to reduce the unnecessary use of anti-epileptic medications and their side effects, and maximizing cost-effective use of video electroencephalography (VEEG). Methods We analyzed PNES subject data from VEEG monitoring performed at the Epilepsy Center at the Marshall University School of Medicine. We reviewed more than 360 episodes in 54 subjects older than 18 years (mean age ± standard deviation (SD): 48 ± 12. Read More

Maladaptive emotional regulation in patients diagnosed with psychogenic non-epileptic seizures (PNES) compared with healthy volunteers.

Seizure 2020 May 13;78:7-11. Epub 2020 Feb 13.

Northeast Regional Epilepsy Group, New York, United States.

Purpose: The term PNES refers to a conversion disorder that mimics epileptic seizures but has a psychological etiology. Recent studies report that in patients with PNES, there is reduced understanding of emotions, impulse control difficulties, and limited access to emotional regulation strategies. The aim of this study was to compare patients diagnosed with PNES with healthy volunteers on the presence of maladaptive emotional regulation. Read More

A Comprehensive Machine-Learning-Based Software Pipeline to Classify EEG Signals: A Case Study on PNES vs. Control Subjects.

Sensors (Basel) 2020 Feb 24;20(4). Epub 2020 Feb 24.

Department of Medical and Surgical Sciences, Magna Graecia University of Catanzaro, 88100 Catanzaro, Italy.

The diagnosis of psychogenic nonepileptic seizures (PNES) by means of electroencephalography (EEG) is not a trivial task during clinical practice for neurologists. No clear PNES electrophysiological biomarker has yet been found, and the only tool available for diagnosis is video EEG monitoring with recording of a typical episode and clinical history of the subject. In this paper, a data-driven machine learning (ML) pipeline for classifying EEG segments (i. Read More
