Malformations of cortical development: The role of 7-Tesla magnetic resonance imaging in diagnosis.

Rev Neurol (Paris) 2019 Mar 1;175(3):157-162. Epub 2019 Mar 1.

Aix-Marseille University, CNRS, CRMBM, 13385 Marseille, France; AP-HM, University Hospital Timone, CEMEREM, 13385 Marseille, France.

Comparison studies between 7T and 1.5 or 3T magnetic resonance imaging (MRI) have demonstrated the added value of ultra-high field (UHF) MRI to better identify, delineate and characterize malformations of cortical development (MCD), and to disambiguate doubtful findings observed at lower field strengths. High resolution structural sequences such as magnetization prepared two rapid acquisition gradient echoes (MP2RAGE), fluid and white matter suppression MP2RAGE (FLAWS), and susceptibility-weighted imaging (SWI) appear to be key to the improvement of MCD diagnosis in clinical practice.

Deep brain activities can be detected with magnetoencephalography.

Nat Commun 2019 02 27;10(1):971. Epub 2019 Feb 27.

Aix Marseille Univ, INSERM, INS, Inst Neurosci Syst, Marseille, 13005, France.

The hippocampus and amygdala are key brain structures of the medial temporal lobe, involved in cognitive and emotional processes as well as pathological states such as epilepsy. Despite their importance, it is still unclear whether their  neural activity can be recorded non-invasively. Here, using simultaneous intracerebral and magnetoencephalography (MEG) recordings in patients with focal drug-resistant epilepsy, we demonstrate a direct contribution of amygdala and hippocampal activity to surface MEG recordings.

Controlling seizure propagation in large-scale brain networks.

PLoS Comput Biol 2019 02 25;15(2):e1006805. Epub 2019 Feb 25.

Aix Marseille Université, Inserm, Institut de Neurosciences des Systèmes, UMR_S 1106, 13005, Marseille, France.

Information transmission in the human brain is a fundamentally dynamic network process. In partial epilepsy, this process is perturbed and highly synchronous seizures originate in a local network, the so-called epileptogenic zone (EZ), before recruiting other close or distant brain regions. We studied patient-specific brain network models of 15 drug-resistant epilepsy patients with implanted stereotactic electroencephalography (SEEG) electrodes. Read More

Large-Scale 3-5 Hz Oscillation Constrains the Expression of Neocortical Fast Ripples in a Mouse Model of Mesial Temporal Lobe Epilepsy.

eNeuro 2019 Jan-Feb;6(1). Epub 2019 Feb 12.

Functional Brain Mapping Laboratory, Department of Fundamental Neuroscience, University of Geneva, 1202 Geneva, Switzerland.

Large-scale slow oscillations allow the integration of neuronal activity across brain regions during sensory or cognitive processing. However, evidence that this form of coding also holds for pathological networks, such as for distributed networks in epileptic disorders, does not yet exist. Here, we show in a mouse model of unilateral hippocampal epilepsy that epileptic fast ripples generated in the neocortex distant from the primary focus occur during transient trains of interictal epileptic discharges.

Cerebrovascular disease burden in late-onset non-lesional focal epilepsy.

Seizure 2019 Mar 8;66:31-35. Epub 2019 Feb 8.

Epilepsy Unit, Neurology Department, Vall d'Hebron University Hospital, Autonomous University of Barcelona, Barcelona, Spain. Electronic address:

Purpose: Late-onset non-lesional focal epilepsy, defined as new-onset seizures in patients older than 60 years, is diagnosed increasingly more often in relation to aging of the population. It has been attributed mainly to occult cerebral small vessel disease (SVD), although high levels of evidence to support this notion are lacking. This study aimed to evaluate the burden of leukoaraiosis, a marker of cerebral SVD, and hippocampal atrophy in patients with late-onset epilepsy (LOE). Read More

Aberrant epileptic seizure identification: A computer vision perspective.

Seizure 2019 Feb 20;65:65-71. Epub 2018 Dec 20.

Department of Mater Advanced Epilepsy Unit, Mater Centre for Neurosciences, Brisbane, Australia.

Purpose: The recent explosion of artificial intelligence techniques in video analytics has highlighted the clinical relevance in capturing and quantifying semiology during epileptic seizures; however, we lack an automated anomaly identification system for aberrant behaviors. In this paper, we describe a novel system that is trained with known clinical manifestations from patients with mesial temporal and extra-temporal lobe epilepsy and presents aberrant semiology to physicians.

Methods: We propose a simple end-to-end-architecture based on convolutional and recurrent neural networks to extract spatiotemporal representations and to create motion capture libraries from 119 seizures of 28 patients. Read More

Human induced pluripotent stem cell-derived MGE cell grafting after status epilepticus attenuates chronic epilepsy and comorbidities via synaptic integration.

Proc Natl Acad Sci U S A 2019 01 17;116(1):287-296. Epub 2018 Dec 17.

Institute for Regenerative Medicine, Texas A&M Health Science Center College of Medicine, Temple, TX 76502;

Medial ganglionic eminence (MGE)-like interneuron precursors derived from human induced pluripotent stem cells (hiPSCs) are ideal for developing patient-specific cell therapy in temporal lobe epilepsy (TLE). However, their efficacy for alleviating spontaneous recurrent seizures (SRS) or cognitive, memory, and mood impairments has never been tested in models of TLE. Through comprehensive video- electroencephalographic recordings and a battery of behavioral tests in a rat model, we demonstrate that grafting of hiPSC-derived MGE-like interneuron precursors into the hippocampus after status epilepticus (SE) greatly restrained SRS and alleviated cognitive, memory, and mood dysfunction in the chronic phase of TLE.

Background: Bitemporal epilepsy (BTLE) is a specific anatomoelectroclinical phenotype in the spectrum of temporal lobe epilepsy. The diagnosis of BTLE and the evaluation of the degree of seizure lateralization in BTLE patients are greatly influenced by the duration of EEG recording and the number of recorded habitual seizures.

Case Description: A 25-year-old woman had a 5-year history of seizures. Read More

Primary idiopathic CNS non-amyloidogenic light chain deposition disease complicated by treatment-resistant focal seizure disorder.

J Clin Neurosci 2019 Jan 10;59:313-315. Epub 2018 Nov 10.

Department of Neurology, Auckland City Hospital, Auckland, New Zealand.

Light chain deposition disease (LCDD) is a systemic disorder characterised by the pathologic deposition of immunoglobulin light chains, which is histologically distinguished from amyloidosis by failure to stain with Congo red. Central nervous system (CNS)-restricted LCDD is among the rarest manifestations. We describe a unique case complicated by focal onset epilepsy with impaired awareness for which control with anticonvulsant therapy proved difficult. Read More

Dual-center, dual-platform microRNA profiling identifies potential plasma biomarkers of adult temporal lobe epilepsy.

EBioMedicine 2018 Dec 2;38:127-141. Epub 2018 Nov 2.

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.

Blocking TNFα-driven astrocyte purinergic signaling restores normal synaptic activity during epileptogenesis.

Glia 2018 12 5;66(12):2673-2683. Epub 2018 Nov 5.

Neuron-glia interactions group, INSERM U1128, Paris Descartes University, Paris, France.

Epilepsy is characterized by unpredictable recurrent seizures resulting from abnormal neuronal excitability. Increasing evidence indicates that aberrant astrocyte signaling to neurons plays an important role in driving the network hyperexcitability, but the underlying mechanism that alters glial signaling in epilepsy remains unknown. Increase in glutamate release by astrocytes participates in the onset and progression of seizures. Read More

Effects of brain-derived neurotrophic factor and noise on transitions in temporal lobe epilepsy in a hippocampal network.

Chaos 2018 Oct;28(10):106322

Cell and Developmental Biology, University College London, London WC1E 6BT, United Kingdom.

Brain-derived neurotrophic factor (BDNF) has recently been implicated in the modulation of receptor activation leading to dynamic state transitions in temporal lobe epilepsy (TLE). In addition, the crucial role of neuronal noise in these transitions has been studied in electrophysiological experiments. However, the precise role of these factors during seizure generation in TLE is not known. Read More

Improved Patient-Independent System for Detection of Electrical Onset of Seizures.

J Clin Neurophysiol 2019 Jan;36(1):14-24

Neurologist and Epileptologist, Gleneagles Global Health City, Chennai, India.

Purpose: To design a non-patient-specific system to detect the electrical onset of seizures in patients with temporal lobe epilepsy.

Methods: We used EEG data from 29 seizures of 18 temporal lobe epilepsy patients who underwent multiday video-scalp EEG monitoring as part of their presurgical evaluations. We segmented each data set into preictal and ictal phases, and identified spectral entropy, spectral energy, and signal energy as useful features for discriminating normal and seizure conditions.

Investigation of paediatric occipital epilepsy using stereo-EEG reveals a better surgical outcome than in adults, especially when the supracalcarine area is affected.

Epileptic Disord 2018 Oct;20(5):346-363

Pediatric Neurosurgery, Rothschild Foundation Hospital, Paris.

Occipital epilepsy is the least common among surgical series because: (1) the location makes it hard to asses by EEG; (2) the seizure semiology often reflects propagation; and (3) surgery entails a high risk of neurological deficits. In children, subjective symptoms are harder to assess, adding to the difficulty of a proper diagnosis. We aimed to determine electroclinical characteristics of occipital lobe epilepsy in a paediatric population by reviewing 20 children between one and 16 years, who had undergone intracranial recordings with depth electrodes.

No Shinkei Geka 2018 Oct;46(10):917-924

Department of Neurosurgery, Kyoto University Graduate School of Medicine.

In recent years, stereotactic electroencephalography(SEEG)has been focused on as a new invasive method for epileptic focus detection. Although the covering area of the brain surface is smaller than the invasive estimation with subdural electrodes, SEEG can evaluate foci that are deeply seated, noncontiguous leaves, and/or bilateral hemispheres. In addition, SEEG can capture consecutive changes in seizure activity in three dimensions. Read More

Ictal SPECT reveals different epileptogenic zones in frontal lobe epilepsy.

Epileptic Disord 2018 Oct;20(5):447-450

Epilepsy Center, Department of Neurology, University of Munich, Munich, Germany.

We report a patient with frontal lobe epilepsy due to a right frontal astrocytoma (WHO Grade III) in whom two ictal SPECTs (single photon emission tomography) were performed during two seizures with different semiology and different EEG seizure patterns. Subtraction of ictal and interictal SPECT showed right lateral frontal hyperperfusion during a left face clonic seizure, and right mesial fronto-polar hyperperfusion during a subclinical seizure. This report demonstrates that ictal SPECT may reflect different seizure semiology from the frontal lobe of the same individual and that simultaneous EEG is indispensable for the correct interpretation of SPECT in epilepsy.
