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.

Ventilatory response to CO in patients with epilepsy.

Epilepsia 2019 Feb 12. Epub 2019 Feb 12.

Department of Neurology, University of Iowa Carver College of Medicine, Iowa City, Iowa.

Objective: Severe periictal respiratory depression is thought to be linked to risk of sudden unexpected death in epilepsy (SUDEP) but its determinants are largely unknown. Interindividual differences in the interictal ventilatory response to CO (hypercapnic ventilatory response [HCVR] or central respiratory CO chemosensitivity) may identify patients who are at increased risk for severe periictal hypoventilation. HCVR has not been studied previously in patients with epilepsy; therefore we evaluated a method to measure it at bedside in an epilepsy monitoring unit (EMU) and examined its relationship to postictal hypercapnia following generalized convulsive seizures (GCSs).

Multi-Modal Home Sleep Monitoring in Older Adults.

J Vis Exp 2019 Jan 26(143). Epub 2019 Jan 26.

Department of Neurology, Washington University School of Medicine; Hope Center for Neurological Disorders, Washington University School of Medicine;

The gold standard for sleep monitoring is attended in-lab polysomnography; however, this method may be cost-prohibitive and inconvenient for patients and research participants. Home sleep testing has gained momentum in the field of sleep medicine due to its convenience and lower cost, as well as being more naturalistic. The accuracy and quality of home sleep testing, however, may be variable because studies are not monitored by sleep technologists. Read More

Sleep disturbances in patients with psychogenic non-epileptic seizures: Is it all subjective? A prospective pilot study of sleep-wake patterns.

Seizure 2019 Feb 17;65:124-128. Epub 2019 Jan 17.

Brigham and Women's Hospital, Department of Neurology, Harvard Medical School, Boston, MA, USA. Electronic address:

Purpose: Patients with psychogenic non-epileptic seizures (PNES) frequently complain of poor sleep, yet there are few and inconsistent data supporting objective sleep disturbances in this population. In this prospective observational study, we aimed to compare objective and subjective sleep-wake patterns in patients with PNES with those with epilepsy.

Methods: Subjects were recruited through the Brigham and Women's Epilepsy Monitoring Unit (EMU) over a 6-month period, and were diagnosed as having PNES or epilepsy by experts using video-electroencephalography (v-EEG). Read More

Referral to evaluation for epilepsy surgery: Reluctance by epileptologists and patients.

Epilepsia 2019 Feb 17;60(2):211-219. Epub 2019 Jan 17.

Epilepsy-Center Berlin-Brandenburg, Department of Neurology, Charité-Universitätsmedizin Berlin, Berlin, Germany.

Objective: Despite the obvious advantages of resective surgery in patients with drug-resistant focal epilepsy, namely high probability of seizure freedom, decreased mortality, and increased quality of life, referral rates from physicians and approval rates by patients for presurgical assessment remain constantly low.

Methods: In the outpatient clinics of a tertiary epilepsy center, checklists were implemented asking treating epileptologists whether they recommended presurgical evaluation with noninvasive video-electroencephalographic monitoring to adult patients with drug-resistant focal epilepsy and asking respective patients whether they followed this recommendation.

Results: Of 185 eligible patients, 80 (43%) were recommended presurgical evaluation by their epileptologists, and 24 (30%) of these patients consented. Read More

Utilization of the Patient Competency Rating Scale in an epileptic and non-epileptic veteran population.

Neurol Sci 2019 Jan 5. Epub 2019 Jan 5.

Neurology Care Line (127), Michael E. DeBakey VA Medical Center, Department of Neurology, Baylor College of Medicine, 2002 Holcombe Blvd., Houston, TX, 77030, USA.

Differentiating between epilepsy and psychogenic non-epileptic events (PNEE) can be difficult given similar presentations. PNEE is often misdiagnosed, resulting in unwarranted treatment with anti-epileptic drugs (AED). While the gold standard for differentiating PNEE from epilepsy is video EEG (VEGG) monitoring, self-reported symptomology has also been shown to discriminate between epilepsy and PNEE with high accuracy, particularly in cases where VEEG is difficult to obtain or when there are no observed events during extended 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.

Automated quantification of EEG spikes and spike clusters as a new read out in Theiler's virus mouse model of encephalitis-induced epilepsy.

Epilepsy Behav 2018 Nov 3;88:189-204. Epub 2018 Oct 3.

Department of Pharmacology, Toxicology, and Pharmacy, University of Veterinary Medicine Hannover, Germany; Center for Systems Neuroscience, Hannover, Germany. Electronic address:

Intracerebral infection of C57BL/6 mice with Theiler's murine encephalomyelitis virus (TMEV) replicates many features of viral encephalitis-induced epilepsy in humans, including neuroinflammation, early (insult-associated) and late (spontaneous) seizures, neurodegeneration in the hippocampus, and cognitive and behavioral alterations. Thus, this model may be ideally suited to study mechanisms involved in encephalitis-induced epilepsy as potential targets for epilepsy prevention. However, spontaneous recurrent seizures (SRS) occur too infrequently to be useful as a biomarker of epilepsy, e. Read More

Assessing the Feasibility of Providing a Real-Time Response to Seizures Detected With Continuous Long-Term Neonatal Electroencephalography Monitoring.

J Clin Neurophysiol 2019 Jan;36(1):9-13

Departments of Pediatrics and Neurosciences, Rady Children's Hospital San Diego, University of California, San Diego, California.

Purpose: Continuous video electroencephalography (cEEG) monitoring is the recommended gold standard of care for at-risk neonates but is not available in many Neonatal Intensive Care Units (NICUs). To conduct a randomized treatment trial of levetiracetam for the first-line treatment of neonatal seizures (the NEOLEV2 trial), we developed a monitoring infrastructure at five NICUs, implementing recent technological advancements to provide continuous video EEG monitoring and real-time response to seizure detection. Here, we report on the feasibility of providing this level of care. Read More

Integrating the systematic assessment of psychological states in the epilepsy monitoring unit: Concept and compliance.

Epilepsy Behav 2018 Nov 10;88:5-14. Epub 2018 Sep 10.

Institute of Synergetics and Psychotherapy Research, Paracelsus Medical University, Salzburg, Austria; Department of Psychiatry, Psychotherapy and Psychosomatics, Paracelsus Medical University, Salzburg, Austria.

Background: Admission to the epilepsy monitoring unit (EMU) for long-term video-electroencephalography (EEG) monitoring (VEEG) constitutes the gold standard for seizure diagnosis and presurgical evaluation. This study applied the concept of a high-frequency systematic monitoring of psychological states and tested patients' compliance in order to evaluate if its integration in the EMU is feasible and if patients benefit from the graphically underpinned discussion of their EMU stay-related cognitions and emotions.

Methods: The process-monitoring is technically realized by an internet-based device for data collection and data analysis, the Synergetic Navigation System (SNS). Read More

The Free Radical Scavenger N-Tert-Butyl-α-Phenylnitrone (PBN) Administered to Immature Rats During Status Epilepticus Alters Neurogenesis and Has Variable Effects, Both Beneficial and Detrimental, on Long-Term Outcomes.

Front Cell Neurosci 2018 28;12:266. Epub 2018 Aug 28.

Department of Developmental Epileptology, Institute of Physiology of the Czech Academy of Sciences, Prague, Czechia.

Status epilepticus (SE), especially in immature animals, is known to produce recurrent spontaneous seizures and behavioral comorbidities later in life. The cause of these adverse long-term outcomes is unknown, but it has been hypothesized that free radicals produced by SE may play a role. We tested this hypothesis by treating immature (P25) rats with the free radical scavenger N-tert-butyl-α-phenylnitrone (PBN) at the time of lithium chloride (LiCl)/pilocarpine (PILO)-induced SE.
