Social cognition in idiopathic generalized epilepsies and potential neuroanatomical correlates.

Epilepsy Behav 2019 Feb 26. Epub 2019 Feb 26.

Neurology Unit, Pisa University Hospital, Pisa, Italy. Electronic address:

Social cognition allows us to elaborate mental representations of social relationships and use them appropriately in a social environment. One of its main attributes is the so-called Theory of Mind (ToM), which consists of the ability to attribute beliefs, intentions, emotions, and feelings to self and others. Investigating social cognition may help understand the poor social outcome often experienced by persons with Idiopathic Generalized Epilepsies (IGE), who otherwise present with normal intelligence.

EFHC1, implicated in juvenile myoclonic epilepsy, functions at the cilium and synapse to modulate dopamine signaling.

Elife 2019 Feb 27;8. Epub 2019 Feb 27.

Department of Molecular Biology and Biochemistry, Simon Fraser University, Burnaby, Canada.

Neurons throughout the mammalian brain possess non-motile cilia, organelles with varied functions in sensory physiology and cellular signaling. Yet, the roles of cilia in these neurons are poorly understood. To shed light into their functions, we studied EFHC1, an evolutionarily conserved protein required for motile cilia function and linked to a common form of inherited epilepsy in humans, juvenile myoclonic epilepsy (JME).

Absence status induced by lacosamide adjunctive therapy.

Epileptic Disord 2019 Feb;21(1):97-101

Department of Neurology and South Texas Comprehensive Epilepsy Center, UT Health San Antonio, San Antonio, Texas.

Since lacosamide was approved as an adjuvant agent for the treatment of medically refractory focal epilepsy over ten years ago, it is becoming more widely used for the treatment of idiopathic (genetic) generalized epilepsies. Several studies have demonstrated efficacy in reducing primary generalized tonic-clonic seizures (GTCS), but efficacy is less well-characterized for myoclonic and absence seizures. A 29-year-old man with juvenile myoclonic epilepsy and medically refractory GTCS on a combination of levetiracetam and topiramate was started on lacosamide adjunctive therapy with the plan to replace topiramate.

EEG of asymptomatic first-degree relatives of patients with juvenile myoclonic, childhood absence and rolandic epilepsy: a systematic review and meta-analysis.

Epileptic Disord 2019 Feb;21(1):30-41

Program in Genetics and Genome Biology, The Hospital for Sick Children, Institute of Medical Science, University of Toronto, Toronto, Division of Neurology, Department of Pediatrics, University of Texas Southwestern, Dallas, USA.

Rolandic (RE), childhood absence (CAE) and juvenile myoclonic (JME) epilepsy encompass centrotemporal sharp waves, 3-Hz spike waves and >3-Hz spike or polyspike waves, respectively. Evidence abounds for genetic roles in all three syndromes, yet involved genes for the vast majority of patients remain unknown. It has long been proposed that while each disease is genetically complex, its specific EEG trait may represent a genetically simpler endophenotype. Read More

Treatment of Juvenile Myoclonic Epilepsy in Patients of Child-Bearing Potential.

CNS Drugs 2019 Mar;33(3):195-208

Epilepsy Unit, Hôpital Gui de Chauliac, 80 Avenue Fliche, 34295, Montpellier Cedex 05, France.

Juvenile myoclonic epilepsy (JME) is both a frequent and a very characteristic epileptic syndrome with female preponderance. Treatment of JME in women of childbearing potential must consider multiple factors such as desire for pregnancy, use of contraception, seizure control and previously used antiepileptic drugs (AEDs). Approximately 85% of cases are well controlled with valproate, which remains the reference AED in JME but is nowadays considered unsafe for the expecting mother and her fetus. Read More

No evidence for a BRD2 promoter hypermethylation in blood leukocytes of Europeans with juvenile myoclonic epilepsy.

Epilepsia 2019 Feb 4. Epub 2019 Feb 4.

Cologne Center for Genomics, University of Cologne, Cologne, Germany.

Juvenile myoclonic epilepsy (JME) is a common syndrome of genetic generalized epilepsies (GGEs). Linkage and association studies suggest that the gene encoding the bromodomain-containing protein 2 (BRD2) may increase risk of JME. The present methylation and association study followed up a recent report highlighting that the BRD2 promoter CpG island (CpG76) is differentially hypermethylated in lymphoblastoid cells from Caucasian patients with JME compared to patients with other GGE subtypes and unaffected relatives.

Remodeling the endoplasmic reticulum proteostasis network restores proteostasis of pathogenic GABAA receptors.

PLoS One 2018 27;13(11):e0207948. Epub 2018 Nov 27.

Department of Physiology and Biophysics, Case Western Reserve University School of Medicine, Cleveland, Ohio, United States of America.

Biogenesis of membrane proteins is controlled by the protein homeostasis (proteostasis) network. We have been focusing on protein quality control of γ-aminobutyric acid type A (GABAA) receptors, the major inhibitory neurotransmitter-gated ion channels in mammalian central nervous system. Proteostasis deficiency in GABAA receptors causes loss of their surface expression and thus function on the plasma membrane, leading to epilepsy and other neurological diseases. Read More

Progressive dissociation of cortical and subcortical network development in children with new-onset juvenile myoclonic epilepsy.

Epilepsia 2018 11 3;59(11):2086-2095. Epub 2018 Oct 3.

Department of Medical Physics, University of Wisconsin School of Medicine and Public Health, Madison, Wisconsin.

Objective: Structural and functional magnetic resonance imaging (MRI) studies have consistently documented cortical and subcortical abnormalities in patients with juvenile myoclonic epilepsy (JME). However, little is known about how these structural abnormalities emerge from the time of epilepsy onset and how network interactions between and within cortical and subcortical regions may diverge in youth with JME compared to typically developing children.

Higher IQ in juvenile myoclonic epilepsy: Dodging cognitive obstacles and "masking" impairments.

Epilepsy Behav 2018 09 14;86:124-130. Epub 2018 Jul 14.

Laboratory of Clinical Neurophysiology, Psychiatry Department, University of São Paulo (USP) School of Medicine, São Paulo, SP, Brazil; Group for the Study of Cognitive and Psychiatric Disorders in Epilepsy-Clinics Hospital, University of São Paulo (USP), Brazil; Center for Interdisciplinary Research on Applied Neurosciences (NAPNA), University of São Paulo (USP), Brazil.

Executive deficits and impulsiveness are extensively reported in juvenile myoclonic epilepsy (JME). Previous literature suggests that intelligence may mediate these deficits. In this study, we evaluated and compared the performance of adults with JME with high and low intelligence quotient (IQ) and controls on tasks for executive function (EF) and impulsive traits.

Evidence of linkage to chromosome 5p13.2-q11.1 in a large inbred family with genetic generalized epilepsy.

Epilepsia 2018 08 4;59(8):e125-e129. Epub 2018 Jul 4.

Epilepsy Research Centre, Austin Health, University of Melbourne, Heidelberg, Victoria, Australia.

The clinical genetics of genetic generalized epilepsy suggests complex inheritance; large pedigrees, with multiple affected individuals, are rare exceptions. We studied a large consanguineous family from Turkey where extensive electroclinical phenotyping revealed a familial phenotype most closely resembling juvenile myoclonic epilepsy. For a subject to be considered affected (n = 14), a diagnostic electroencephalogram was required. Read More

Clinical and genetic study of Tunisian families with genetic generalized epilepsy: contribution of CACNA1H and MAST4 genes.

Neurogenetics 2018 Aug 12;19(3):165-178. Epub 2018 Jun 12.

UPMC Univ Paris 06, Inserm, CNRS, APHP, Institut du Cerveau et la Moelle (ICM), Hôpital Pitié-Salpêtrière, Sorbonne Universités, Paris, France.

Genetic generalized epilepsies (GGE) (childhood absence epilepsy (CAE), juvenile myoclonic epilepsy (JME) and epilepsy with generalized tonic-clonic seizures (GTCS)) are mainly determined by genetic factors. Since few mutations were identified in rare families with autosomal dominant GGE, a polygenic inheritance was suspected in most patients. Recent studies on large American or European cohorts of sporadic cases showed that susceptibility genes were numerous although their variants were rare, making their identification difficult.
