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

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.

Authors:
Jorge Vidaurre

Medicina (B Aires) 2018 ;78 Suppl 2:25-29

Nationwide Children's Hospital, The Ohio State University, Ohio, USA. E-mail:

Neonatal seizures are common expression of acute brain injury in the perinatal period and could potentiate the degree of neuronal injury. The majority of events are electroencephalographic and the clinical seizures can be subtle and difficult to identify by medical personnel. Neonatal seizures are usually short and frequent at onset and have a tendency to subside after a short period. Read More

Sleep-disordered breathing, neuroendocrine function, and clinical SUDEP risk in patients with epilepsy.

Epilepsy Behav 2018 Aug 31;87:78-82. Epub 2018 Aug 31.

Comprehensive Epilepsy and Sleep Center, Department of Neurology, Columbia University Medical Center New York, NY, United States.

Introduction: Sudden unexpected death in epilepsy (SUDEP) is a major contributor to epilepsy-related mortality. It is associated with nocturnal seizures and centrally mediated postictal cardiorespiratory dysfunction (CRD), but mechanisms and contributors remain poorly understood.

Methods: We performed a prospective, cross-sectional, observational pilot study in the Columbia University Medical Center (CUMC) adult epilepsy monitoring unit (EMU) to explore relationships between periictal CRD, sleep-disordered breathing (SDB), neuroendocrine function, and clinical SUDEP risk.

Early outcomes of stereoelectroencephalography followed by MR-guided laser interstitial thermal therapy: a paradigm for minimally invasive epilepsy surgery.

Neurosurg Focus 2018 Sep;45(3):E8

Department of Neurosurgery, Children's National Medical Center, Washington, DC.

OBJECTIVE Stereoelectroencephalography (sEEG) and MR-guided laser interstitial thermal therapy (MRgLITT) have both emerged as minimally invasive alternatives to open surgery for the localization and treatment of medically refractory lesional epilepsy. Although some data are available about the use of these procedures individually, reports are almost nonexistent on their use in conjunction. The authors' aim was to report early outcomes regarding efficacy and safety of sEEG followed by MRgLITT for localization and ablation of seizure foci in the pediatric population with medically refractory lesional epilepsy.

Multimodal localization and surgery for epileptic spasms of focal origin: a review.

Neurosurg Focus 2018 Sep;45(3):E4

Division of Neurosurgery, The Hospital for Sick Children, Toronto, Ontario, Canada.

Epileptic spasms (ES) are a common manifestation of intractable epilepsy in early life and can lead to devastating neurodevelopmental consequences. Epilepsy surgery for ES is challenging because of inherent difficulties in localizing the epileptogenic zone in affected infants and children. However, recent clinical series of resective neurosurgery for ES suggest that not only is surgery a viable option for appropriately selected patients, but postoperative seizure outcomes can be similar to those achieved in other types of focal epilepsy.

Phase-amplitude coupling between interictal high-frequency activity and slow waves in epilepsy surgery.

Epilepsia 2018 Oct 26;59(10):1954-1965. Epub 2018 Aug 26.

Department of Pediatrics, Children's Hospital of Michigan, Wayne State University, Detroit Medical Center, Detroit, Michigan.

Objective: We hypothesized that the modulation index (MI), a summary measure of the strength of phase-amplitude coupling between high-frequency activity (>150 Hz) and the phase of slow waves (3-4 Hz), would serve as a useful interictal biomarker for epilepsy presurgical evaluation.

Methods: We investigated 123 patients who underwent focal cortical resection following extraoperative electrocorticography recording and had at least 1 year of postoperative follow-up. We examined whether consideration of MI would improve the prediction of postoperative seizure outcome. Read More

Ictal nausea and vomiting - Is it left or right?

Seizure 2018 Oct 12;61:83-88. Epub 2018 Aug 12.

Department of Neurology, University Hospital Zurich, Zurich, Switzerland; University of Zurich, Zurich, Switzerland.

Purpose: Ictal nausea/vomiting has been linked to the non-dominant hemisphere and has been considered a lateralizing sign. However, small case series and single cases have reported seizure localisation in the dominant hemisphere. Here we aimed to determine the seizure localisation and lateralization in cases with ictal nausea/retching/vomiting to test the hypothesis that these signs are of lateralizing value. Read More

Probable dysimmune epilepsia partialis continua manifesting as epileptic moving toes syndrome: electroclinical features of a challenging case.

Epileptic Disord 2018 Aug;20(4):301-312

Department of Neurology, Christian Doppler Klinik, Paracelsus Medical University, Salzburg Austria, Centre for Cognitive Neuroscience Salzburg, Austria, Department of Public Health Technology Assessment, UMIT - University for Health Sciences, Medical Informatics and Technology, Hall.i.T., Austria.

Epilepsia partialis continua (EPC) is a rare form of focal status epilepticus. We describe a 22-year-old woman with EPC manifesting with isolated toe movements, prevalent over the left side and initially misdiagnosed as psychogenic, clinically almost indistinguishable from those observed in "painful legs and moving toes syndrome". The continuous involuntary movements with EMG correlates of twitches lasting <100 ms, the sharp waves over fronto-central regions on EEG, and the marked asymmetry in somatosensory evoked potentials with higher cortical amplitude over the right side following peripheral stimulation over the left foot confirmed the epileptic nature of the symptoms, leading to the diagnosis of EPC.
