The influence of attachment style and relationship quality on quality of life and psychological distress in carers of people with epileptic and nonepileptic seizures.

Epilepsy Behav 2019 Feb 16;93:16-21. Epub 2019 Feb 16.

Sheffield Teaching Hospitals NHS Foundation Trust, Royal Hallamshire Hospital, Glossop Road, Sheffield S10 2JF, United Kingdom; Academic Neurology Unit, University of Sheffield, Royal Hallamshire Hospital, Glossop Road, Sheffield S10 2JF, United Kingdom.

Background: Seizure disorders affect not only the individual living with seizures, but also those caring for them. Carer-patient relationships may be influenced by, and have an influence on, some aspects of living with seizure disorders - with potentially different interactions seen in epilepsy and psychogenic nonepileptic seizures (PNES).

Objectives: We studied the influence of patient and carer attachment style and relationship quality on carer wellbeing and psychological distress, and explored whether these associations differ between carers for people with epilepsy and for those with PNES. Read More

Quality of life and psychological dysfunction in traumatized and nontraumatized patients with psychogenic nonepileptic seizures (PNES).

Epilepsy Behav 2019 Feb 12;92:341-344. Epub 2019 Feb 12.

CAPHRI School for Public Health and Primary Care, Department of Health Services Research, Maastricht University, Maastricht, the Netherlands; Centre for Economic Evaluation, Trimbos Institute, Netherlands Institute of Mental Health and Addiction, Utrecht, the Netherlands.

Objectives: Psychogenic nonepileptic seizures (PNES) have the appearance of epileptic seizures, yet show no epileptiform discharges in the brain. The quality of life (QOL) in patients with PNES is reportedly low and trauma eems to be a relevant risk factor. The objective of this study was to examine the difference between measures of (epilepsy-specific) QOL (Quality of Life in Epilepsy Inventory; QOLIE-31p) and psychological dysfunction (trauma symptom inventory; TSI) between patients with diagnosed PNES with self-reported trauma and those without self-reported trauma.

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

Questionnaires or symptom lists have proved effective for differentiating epileptic seizures (ES) from psychogenic nonepileptic seizures (PNES). However, monitoring the events, corroborated by medical history gathered by experts, remains the gold standard. We directly compared symptoms and characteristic of the events self-reported by patients/eyewitnesses (Questionnaire A/B) with the information contained in the clinical charts of 50 patients with undefined diagnosis undergoing long-term monitoring.

Semiological characteristics of patients with psychogenic nonepileptic seizures: Gender-related differences.

Epilepsy Behav 2018 Dec 8;89:130-134. Epub 2018 Nov 8.

Department of Neurology, Karadeniz Technical University Medical Faculty, 61080 Trabzon, Turkey.

Psychogenic nonepileptic seizures (PNES) are more prevalent among women, and diagnosis may sometimes be delayed by as much as seven years. Understanding the effect of gender on the presentation of a PNES may assist with diagnosis based on semiological details in the clinical setting. Although video-EEG monitoring (VEM) is the gold standard for diagnosing PNES, determining gender-related seizure semiology through careful history may prevent diagnostic delay while waiting for VEM.

Department of Physiology & Medical Physics, RCSI, Dublin, Ireland; FutureNeuro Research Centre, RCSI, Dublin, Ireland. Electronic address:

Background: There are no blood-based molecular biomarkers of temporal lobe epilepsy (TLE) to support clinical diagnosis. MicroRNAs are short noncoding RNAs with strong biomarker potential due to their cell-specific expression, mechanistic links to brain excitability, and stable detection in biofluids. Altered levels of circulating microRNAs have been reported in human epilepsy, but most studies collected samples from one clinical site, used a single profiling platform or conducted minimal validation.

From the Department of Neurology, Functional Neurology Research Group, Cognitive Behavioral Neurology Unit, Massachusetts General Hospital, Harvard Medical School, Boston (BW, JPO, RJ, DLP); the Department of Psychiatry, Benson-Henry Institute for Mind Body Medicine, Massachusetts General Hospital, Boston (GLF); and the Department of Psychiatry, Neuropsychiatry Unit, Massachusetts General Hospital, Harvard Medical School, Boston (DLP).

Insecure attachment is a predisposing risk factor for the development of functional neurological disorder (FND). There is limited research investigating connections between attachment styles, other predisposing vulnerabilities, and symptom severity in patients with motor FND. By using a within-group design with prospective data collection, the authors performed univariate tests followed by multivariate linear regressions to investigate neuropsychiatric factors associated with four attachment styles (secure, fearful, preoccupied, and dismissing) among 56 patients with motor FND (mean age=40.

Benefits of additional cardiologic examination in patients admitted for differential diagnosis to the Epilepsy Center Bethel.

Epilepsy Res 2018 12 16;148:44-47. Epub 2018 Oct 16.

Epilepsy Center Bethel, Krankenhaus Mara, Bielefeld, Germany.

Additional cardiologic examination for syncope is used for patients admitted for diagnostic reasons in the Epilepsy Center Bethel if, after epileptologic examination, the etiology of seizures remains uncertain and a cardiologic etiology is suspected. Therefore, we retrospectively analyzed all patient data from the diagnostic department between 02/2011 and 07/2015 to evaluate the benefits to patients of additional cardiologic examination for syncope. 78 out of 1567 patients underwent additional cardiologic examination for syncope.

Can home videos made on smartphones complement video-EEG in diagnosing psychogenic nonepileptic seizures?

Seizure 2018 Nov 3;62:95-98. Epub 2018 Oct 3.

All India Institute of Medical Sciences, New Delhi, India. Electronic address:

Purpose: To assess the contribution home-videos made on mobile phones can make to the diagnosis of Psychogenic Nonepileptic Seizures (PNES).

Methods: Consecutive patients 10-50 years old, with episodes of altered behavior or abnormal movements, unresponsiveness, or falls, were recruited after they had obtained 'good' or 'fair' quality (quality of video scale (QOV)) home-videos of their episodes on personal mobile phones; these subjects underwent video-electroencephalography (VEEG). Diagnoses of PNES, other physiological events or epileptic seizure (ES) on home-videos (by the epilepsy fellow, step 1) and on VEEGs (by a fully trained epileptologist unaware of the home-video recording, step 2) were compared.

Provocative induction of psychogenic nonepileptic seizures: Noninferiority of an induction technique without versus with placebo.

Epilepsia 2018 Nov 1;59(11):e161-e165. Epub 2018 Oct 1.

Neurology Care Line, Michael E. DeBakey Veterans Affairs Medical Center, Houston, Texas.

We aim to demonstrate, in a sufficiently powered and standardized study, that the success rate of inducing psychogenic nonepileptic seizures (PNES) without placebo (saline infusion) is noninferior to induction with placebo. The clinical data of 170 consecutive patients with suspected PNES who underwent induction with placebo from January 21, 2009 to March 31, 2013 were pair-matched with 170 consecutive patients with suspected PNES who underwent the same induction technique but without addition of placebo from April 1, 2013 to February 7, 2018 at the same center. The success rates of induction were 79. Read More

Italy Institutes of Neurology, Department of Medical and Surgical Sciences, Magna Græcia University of Catanzaro, Catanzaro, Italy. Electronic address:

Psychogenic nonepileptic seizures (PNES) are episodes of paroxysmal impairment associated with a range of motor, sensory, and mental manifestations, which perfectly mimic epileptic seizures. Several patterns of neural abnormalities have been described without identifying a definite neurobiological substrate. In this multicenter cross-sectional study, we applied a multivariate classification algorithm on morphological brain imaging metrics to extract reliable biomarkers useful to distinguish patients from controls at an individual level.
