Evaluation of Seizure Etiology From Routine Testing to Genetic Evaluation.

Continuum (Minneap Minn) 2019 Apr;25(2):322-342

Purpose Of Review: Recognizing the cause of a first seizure and identifying the etiology of epilepsy are essential for management. A systematic approach to patients who present with a first seizure helps distinguish between an acute symptomatic seizure, a provoked or unprovoked seizure, and potential mimickers. Routine testing with EEG and MRI may reveal a predisposition for further seizures and help to establish the underlying epilepsy syndrome. Read More

Epilepsy in Children with Autistic Spectrum Disorder.

Children (Basel) 2019 Jan 25;6(2). Epub 2019 Jan 25.

Department of Pediatrics and Medical Genetics, Medical University-Plovdiv,4000, Bulgaria.

The comorbidity of autistic spectrum disorder (ASD) and epilepsy has been widely discussed but many questions still remain unanswered. The aim of this study was to establish the occurrence of epilepsy among children with ASD to define the type of epileptic seizures and syndromes, the age of onset of epilepsy, EEG abnormalities, the used antiepileptic drugs and the therapeutic responses for seizures and autistic behavior, as well as to find some correlations between epilepsy and gender, etiology and intellectual disability (ID). A retrospective study of medical files of 59 patients (aged 1⁻18 years) with ASD during a 5-year period was performed. Read More

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.

Asynchronous suppression of visual cortex during absence seizures in stargazer mice.

Nat Commun 2018 05 16;9(1):1938. Epub 2018 May 16.

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

Absence epilepsy is a common childhood disorder featuring frequent cortical spike-wave seizures with a loss of awareness and behavior. Using the calcium indicator GCaMP6 with in vivo 2-photon cellular microscopy and simultaneous electrocorticography, we examined the collective activity profiles of individual neurons and surrounding neuropil across all layers in V1 during spike-wave seizure activity over prolonged periods in stargazer mice. We show that most (~80%) neurons in all cortical layers reduce their activity during seizures, whereas a smaller pool activates or remains neutral. Read More

In this study we conducted a longitudinal assessment of spontaneous cortical electrographic discharges in female MeCP2-deficient mice and defined the pharmacological responsiveness of these discharges to anti-convulsant drugs.

SPECT perfusion changes during ictal automatisms with preserved responsiveness in patients with right temporal lobe epilepsy.

Epilepsy Behav 2018 03 20;80:11-14. Epub 2018 Jan 20.

Department of Neurology, Samsung Medical Center, Sungkyunkwan University School of Medicine, Republic of Korea; Neuroscience Center, Samsung Medical Center, Republic of Korea.

Ictal automatism with preserved responsiveness (APR) has been reported, particularly in nondominant temporal lobe epilepsy (TLE), but its pathophysiology remains poorly understood. This study sought to investigate the relationship between APRs and increased cerebral blood flow (CBF) using ictal single photon emission computed tomography (SPECT) in TLE. Forty-seven subjects with right mesial TLE (15 with and 32 without APR) were enrolled. Read More

Insulo-opercular cortex generates oroalimentary automatisms in temporal seizures.

Epilepsia 2018 03 2;59(3):583-594. Epub 2018 Feb 2.

Epilepsy Center, Cleveland Clinic Neurological Institute, Cleveland, OH, USA.

Objective: Oroalimentary automatisms (OAAs) resembling normal alimentary behavior are stereotyped complex movements that may occur during epileptic seizures. They are considered common clinical signs in temporal lobe seizures, but their anatomofunctional mechanisms are not established. We took the opportunity of presurgical intracerebral recordings to study the relations between the occurrence of OAAs and temporal/spatial features of ictal activities. Read More

Juvenile myoclonic epilepsy and sleep.

Epilepsy Behav 2018 03 19;80:326-330. Epub 2018 Jan 19.

Tianjin Medical University General Hospital, No.154 Anshan Road, Heping District, Tianjin 300052, China. Electronic address:

Juvenile myoclonic epilepsy (JME) is a sleep-related epilepsy syndrome, and only a few studies have addressed the relationship between JME and sleep disorders. In this review, the sleep characteristics of patients with JME were summarized based on the features of circadian rhythm, the possible cause of the early morning seizures, the common subjective and objective sleep disorders, the alterations in sleep architecture, and the effect of sleep deprivation and sodium valproate (VPA). The aims of this study were to summarize the interaction between JME and sleep, to reveal JME sleep characteristics, to encourage clinicians to focus on JME and sleep, to heighten the positive diagnosis rate, to guide the treatment, to improve the prognosis, and to enhance the daily life quality of patients with JME.

Gamma oscillatory activity in vitro: a model system to assess pathophysiological mechanisms of comorbidity between autism and epilepsy.

Transl Psychiatry 2018 01 10;8(1):16. Epub 2018 Jan 10.

Department of Neurological Sciences, Christian Medical College, Vellore, India.

Autism spectrum disorder (ASD) and temporal lobe epilepsy exhibit remarkable comorbidity, but for reasons not clearly understood. To reveal a common pathophysiological mechanism, we here describe and characterize an in vitro epileptiform activity in the rat hippocampus that exhibits common features with in vivo activity in rodent ASD models. We discovered the development of this activity in the CA1 region of horizontal slices after prolonged interictal-like epileptiform activity in the CA3 region that was provoked by incubation in high potassium artificial cerebrospinal fluid.

Department of Child Neurology, Asahigawaso Rehabilitation and Medical Center, 866 Gion, Kita-ku, Okayama, Japan. Electronic address:

Vigabatrin was approved for the treatment of infantile spasms by the US Food and Drug Administration, but not in Japan at the time of initiating this clinical study because of concerns about irreversible peripheral visual field defects (VFDs). This study evaluated the efficacy and safety of vigabatrin for Japanese patients with infantile spasms. Of 15 patients (aged ≥4weeks and <2years) enrolled, with the exception of two patients who did not receive vigabatrin, 13 were treated with a titrated dosage of vigabatrin (50-150mg/kg/day; limited to 3000mg/day).

Department of Neurology, David Geffen School of Medicine and Mattel Children's Hospital UCLA, Los Angeles, CA; Department of Neurology, University of Colorado School of Medicine, Aurora, CO.

Objectives: To characterize and quantify diagnostic and treatment delay among children with infantile spasms, and to estimate the developmental impact of this delay.

Study Design: In this cohort study, we surveyed the parents of 100 patients with infantile spasms about their experiences with diagnosis and treatment, and ascertained medical and sociodemographic factors potentially related to care of these infants. We specifically determined the latency to first visit an "effective provider," defined as a provider who identified infantile spasms, and prescribed an appropriate first-line treatment, namely adrenocorticotropic hormone, corticosteroids, or vigabatrin.

Cognitive and behavioral comorbidities in Rolandic epilepsy and their relation with default mode network's functional connectivity and organization.

Epilepsy Behav 2018 01 2;78:179-186. Epub 2017 Nov 2.

Faculty of Medicine, University of Freiburg, Germany; Clinic for Radiology, Medical Physics, Medical Center - University of Freiburg, Germany.

Objective: Rolandic epilepsy (RE) is characterized by typical interictal-electroencephalogram (EEG) patterns mainly localized in centrotemporal and parietooccipital areas. An aberrant intrinsic organization of the default mode network (DMN) due to repeated disturbances from spike-generating areas may be able to account for specific cognitive deficits and behavioral problems in RE. The aim of the present study was to investigate cognitive development (CD) and socioemotional development (SED) in patients with RE during active disease in relation to DMN connectivity and network topology.

Child Neurology, Headache Paediatric Center, Paediatric Sleep Disorders, NESMOS Department, Chair of Pediatrics, Faculty of Medicine and Psychology, Sapienza University, c/o Sant'Andrea Hospital, Rome, Italy.

Benign epilepsy with centrotemporal spikes (BECTS) epilepsy, also known as rolandic epilepsy, is the most common childhood type of epilepsy. There is debate on its "benign" definition given the numerous literature data on its correlation to cognitive morbidity. Although its prognosis is often favorable, BECTS can present or evolve however to an atypical form, characterized by a worse prognosis and negative impact on cognitive development. Read More

Atonic seizures in children with surgically remediable epilepsy: a motor system seizure phenotype?

Epileptic Disord 2017 Sep;19(3):315-326

Medical and Surgical Epilepsy Unit, Hautepierre Hospital, University of Strasbourg, Strasbourg, IDEE Epilepsy Institute, Lyon, France.

Atonic seizures are common in some epileptic syndromes beginning in infancy or early childhood but they are rarely described in epilepsy with focal seizures of structural aetiology. We aimed to characterize the electroclinical features of atonic seizures in surgically remediable paediatric patients and to study the spatiotemporal organization of the underlying epileptogenic networks. We retrospectively analysed two consecutive, longitudinally evaluated and surgically treated paediatric patients presenting with atonic seizures as a manifestation of pharmacoresistant epilepsy of structural aetiology, evidenced by scalp- and stereotactic intracerebral video-EEG-recordings.
