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.

Could Rolandic spikes be a prognostic factor of the neurocognitive outcome of children with BECTS?

Epilepsy Behav 2018 09 19;86:157-162. Epub 2018 Jul 19.

"La Sapienza" University, Department of Pediatrics, Child Neurology Division, Italy. Electronic address:

Introduction: Rolandic epilepsy, also known as benign childhood epilepsy with centrotemporal spikes (BECTS), is one of the most common epileptic syndromes in previously healthy children. Despite what was known about the benignity of this syndrome, there is always more evidence about the involvement of the cognitive functions with different deficits in several domains to be investigated.

Aim Of The Study: The aim of our study was to describe prognostic electroencephalogram (EEG) pattern of an adverse cognitive development to recognize patients at higher risk of lasting cognitive deficits that could need antiepileptic drugs (AEDs) or an improved neurocognitive therapy. Read More

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

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.

"Atypical forms" of benign epilepsy with centrotemporal spikes (BECTS): How to diagnose and guide these children. A practical/scientific approach.

Epilepsy Behav 2017 10 1;75:165-169. Epub 2017 Sep 1.

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.

Rationale for an adjunctive therapy with fenofibrate in pharmacoresistant nocturnal frontal lobe epilepsy.

Epilepsia 2017 10 2;58(10):1762-1770. Epub 2017 Aug 2.

Neuroscience Institute, National Research Council of Italy, Cagliari, Italy.

Objective: Nocturnal frontal lobe epilepsy (NFLE) is an idiopathic partial epilepsy with a family history in about 25% of cases, with autosomal dominant inheritance (autosomal dominant NFLE [ADNFLE]). Traditional antiepileptic drugs are effective in about 55% of patients, whereas the rest remains refractory. One of the key pathogenetic mechanisms is a gain of function of neuronal nicotinic acetylcholine receptors (nAChRs) containing the mutated α4 or β2 subunits. Read More

Epileptic Encephalopathies as Neurodegenerative Disorders.

Adv Neurobiol 2017 ;15:295-315

Division of Child Neurology, The Children's Hospital of Philadelphia, 34th St and Civic Center Blvd, Philadelphia, PA, 19104, USA.

The epileptic encephalopathies are severe and often treatment-resistant conditions that are associated with a progressive disturbance of brain function, resulting in a broad range of neurological and non-neurological comorbidities. The concept of epileptic encephalopathies entails that the encephalopathy aspect of the overall condition is primarily driven by the epileptic activity of the disease, which often manifests as specific and pathological features on the electroencephalogram. Genetic factors in epileptic encephalopathies are increasingly recognized. Read More

De novo 12q22.q23.3 duplication associated with temporal lobe epilepsy.

Seizure 2017 Aug 15;50:80-82. Epub 2017 Jun 15.

Laboratory of Neurogenetics and Neuroscience, "G. Gaslini" Institute, Genova, Italy.

Purpose: Temporal lobe epilepsy (TLE) is the most common form of focal epilepsy and may be associated with acquired central nervous system lesions or could be genetic. Various susceptibility genes and environmental factors are believed to be involved in the aetiology of TLE, which is considered to be a heterogeneous, polygenic, and complex disorder. Rare point mutations in LGI1, DEPDC5, and RELN as well as some copy number variations (CNVs) have been reported in families with TLE patients. Read More

Role of Electroencephalography in the Diagnosis and Treatment of Neuropsychiatric Border Zone Syndromes.

Indian J Psychol Med 2017 May-Jun;39(3):243-249

Department of Psychiatry, National Institute of Mental Health and Neurosciences, Bengaluru, Karnataka, India.

Border zone disorders involve neurological disorders with psychiatric symptoms and signs as well as psychiatric disorders with soft neurological features. This becomes a cause for great diagnostic and therapeutic concerns. We, in this paper, analyzed some of the imitators such as epilepsy, dementia, some forms of encephalitis, and pure psychiatric diseases which produce problems in decision making due to soft neurological features and the utility of electroencephalography (EEG) as a simple diagnostic tool in differentiating some of these conditions from each other as well as the therapeutic role of EEG in some of these disorders.

Functional Network Connectivity Patterns between Idiopathic Generalized Epilepsy with Myoclonic and Absence Seizures.

Front Comput Neurosci 2017 23;11:38. Epub 2017 May 23.

Department of Neurology, First Affiliated Hospital of Hainan Medical UniversityHaikou, China.

The extensive cerebral cortex and subcortical structures are considered as the major regions related to the generalized epileptiform discharges in idiopathic generalized epilepsy. However, various clinical syndromes and electroencephalogram (EEG) signs exist across generalized seizures, such as the loss of consciousness during absence seizures (AS) and the jerk of limbs during myoclonic seizures (MS). It is presumed that various functional systems affected by discharges lead to the difference in syndromes of these seizures. Read More
