Seizures as a clinical manifestation in somatic autoimmune disorders.

Seizure 2018 Dec 5;64:59-64. Epub 2018 Dec 5.

Stichting Epilepsie Instellingen Nederland (SEIN), Achterweg 5, Heemstede, 2103SW, Netherlands; NIHR University College London Hospitals Biomedical Research Centre, UCL Queen Square Institute of Neurology, London, WC1N 3BG, United Kingdom; Chalfont Centre for Epilepsy, Chalfont St Peter, Bucks, SL9 0RJ, United Kingdom.

The risk of epileptic seizures seems increased in several systemic autoimmune disorders including systemic lupus erythematosus, type 1 diabetes mellitus, myasthenia gravis, celiac disease, rheumatoid arthritis, Hashimoto's encephalopathy, psoriasis, multiple sclerosis, neuromyelitis optica, and bullous pemphigoid. Immune dysfunction may be partly responsible for this association. Elevated levels of pro-inflammatory cytokines, autoantibodies seen in these autoimmune disorders and antibodies against neuronal antigens may contribute to the etiopathogenesis of seizures and epilepsy associated to immune conditions.

Kufs disease due to mutation of CLN6: clinical, pathological and molecular genetic features.

Brain 2018 Dec 15. Epub 2018 Dec 15.

Consultant in Neuropathology, Centro Hospitalar São João, Porto, Portugal.

Kufs disease is the major adult form of neuronal ceroid lipofuscinosis, but is rare and difficult to diagnose. Diagnosis was traditionally dependent on the demonstration of characteristic storage material, but distinction from normal age-related accumulation of lipofuscin can be challenging. Mutation of CLN6 has emerged as the most important cause of recessive Kufs disease but, remarkably, is also responsible for variant late infantile ceroid lipofuscinosis. Read More

Connectivity and Centrality Characteristics of the Epileptogenic Focus Using Directed Network Analysis.

IEEE Trans Neural Syst Rehabil Eng 2018 Dec 11. Epub 2018 Dec 11.

Accurate epileptogenic focus localization is required prior to surgical resection of brain tissue for treatment of patients with antiepileptic drug resistant (intractable) epilepsy. This clinical need is only partially fulfilled through a subjective, and at times inconclusive, evaluation of the recorded electroence-phalogram (EEG) at seizures' onset (the so-called gold standard for focus localization in epilepsy). We herein present a novel method of multivariate analysis of the EEG that appears to be very promising for an objective and robust localization of the epileptogenic focus at seizures' onset.

Metabolic Evaluation of Epilepsy: A Diagnostic Algorithm With Focus on Treatable Conditions.

Front Neurol 2018 3;9:1016. Epub 2018 Dec 3.

Division of Genetics and Metabolism, Children's National Health System, Washington, DC, United States.

Although inborn errors of metabolism do not represent the most common cause of seizures, their early identification is of utmost importance, since many will require therapeutic measures beyond that of common anti-epileptic drugs, either in order to control seizures, or to decrease the risk of neurodegeneration. We translate the currently-known literature on metabolic etiologies of epilepsy (268 inborn errors of metabolism belonging to 21 categories, with 74 treatable errors), into a 2-tiered diagnostic algorithm, with the first-tier comprising accessible, affordable, and less invasive screening tests in urine and blood, with the potential to identify the majority of treatable conditions, while the second-tier tests are ordered based on individual clinical signs and symptoms. This resource aims to support the pediatrician, neurologist, biochemical, and clinical geneticists in early identification of treatable inborn errors of metabolism in a child with seizures, allowing for timely initiation of targeted therapy with the potential to improve outcomes.

Oxford Autoimmune Neurology Group, Nuffield Department of Clinical Neurosciences, University of Oxford, Oxford, UK.

Anti-myelin oligodendrocyte glycoprotein (MOG) antibodies (MOG-Abs) were first detected by immunoblot and enzyme-linked immunosorbent assay nearly 30 years ago, but their association with multiple sclerosis (MS) was not specific. Use of cell-based assays with native MOG as the substrate enabled identification of a group of MOG-Ab-positive patients with demyelinating phenotypes. Initially, MOG-Abs were reported in children with acute disseminated encephalomyelitis (ADEM). 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 2018 Dec 17. 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.

We present a 29-year-old man with visual failure since childhood, muscle weakness, subtle heart muscle hypertrophy, and seizures who was initially considered to be affected by a mitochondrial encephalomyopathy because of the multiple unspecific involvement of brain, muscle and retinal tissues. Only the muscle biopsy findings correctly guided the genetic investigations and the identification of an autophagic vacuolar myopathy due to a homozygous mutation in CLN3. We believe that information in autophagic muscle disorders should further alert clinicians to consider CLN3 in individuals with vacuolar myopathy, especially if they have visual and cardiac involvement.

Intravenously Administered Ganaxolone Blocks Diazepam- Resistant Lithium-Pilocarpine-Induced Status Epilepticus in Rats. Comparison with Allopregnanolone.

J Pharmacol Exp Ther 2018 Dec 14. Epub 2018 Dec 14.

University of Washington School of Pharmacy.

Ganaxolone (GNX) is the 3β-methylated synthetic analog of the naturally occurring neurosteroid, allopregnanolone (ALLO). GNX is effective in a broad range of epilepsy and behavioral animal models and is currently in clinical trials designed to assess its anticonvulsant and antidepressant activities. The current studies were designed to broaden the anticonvulsant profile of GNX by evaluating its potential anticonvulsant activities following intravenous (IV) administration in treatment resistant models of status epilepticus (SE), to establish a pharmacokinetic (PK)/pharmacodynamics (PD) relationship, and to compare its PK and anticonvulsant activities to ALLO.

Synthetic cannabinoid hydroxypentyl metabolites retain efficacy at human cannabinoid receptors.

J Pharmacol Exp Ther 2018 Dec 14. Epub 2018 Dec 14.

RTI International;

Synthetic cannabinoids (SCs) are novel psychoactive substances that are easily acquired, widely abused as a substitute for cannabis, and associated with cardiotoxicity and seizures. While the structures of these compounds are based upon scaffolds with known affinity and efficacy at the human cannabinoid type-1 receptor (hCB), upon ingestion or inhalation they can be metabolized to multiple chemical entities of unknown pharmacological activity. A large proportion of these metabolites are hydroxylated on the pentyl chain, a key substituent that determines receptor affinity and selectivity. Read More

Ivabradine possesses anticonvulsant and neuroprotective action in mice.

Biomed Pharmacother 2019 Jan 2;109:2499-2512. Epub 2018 Dec 2.

Neuropsychopharmacology Laboratory, Department of Physiology and Pharmacology, Faculty of Medicine, Federal University of Ceará (UFC), Fortaleza, CE, Brazil. Electronic address:

We analyzed whether ivabradine (IVA), a hyperpolarization-activated cyclic nucleotide-gated (HCN) channel blocker, clinically used for angina and arrhythmia, had anticonvulsant, antioxidant and neuroprotective properties against classical seizure models. Potential molecular targets to IVA anticonvulsant effects were evaluated by molecular docking. Mice were treated with IVA (1, 10 or 20 mg/kg, IP) for 3 days, and 30 min after the last administration were injected with pentylenetetrazole (PTZ - 85 mg/kg, IP), pilocarpine (PILO 400 mg/kg, SC), picrotoxin (PICRO 10 mg/kg, IP).

The T-type calcium channel antagonist, Z944, alters social behavior in Genetic Absence Epilepsy Rats from Strasbourg.

Behav Brain Res 2018 Dec 11. Epub 2018 Dec 11.

University of Saskatchewan, Department of Physiology, Saskatoon, SK, Canada.

Abnormalities in social behavior are a co-morbid symptom of idiopathic generalized epilepsies such as childhood absence epilepsy. The Genetic Absence Epilepsy Rats from Strasbourg (GAERS) model is a spontaneously occurring absence epilepsy phenotype closely correlated to that of human absence epilepsies. Similar to the human conditions, GAERS display social abnormalities. Read More

Sensory coding is impaired in rat absence epilepsy.

J Physiol 2018 Dec 13. Epub 2018 Dec 13.

Univ. Grenoble Alpes, Grenoble Institut des Neurosciences, GIN, F-38000, Grenoble, France.

Key Points: Absence epilepsy is characterized by the occurrence of spike-and-wave discharges concomitant with an alteration of consciousness and associated with cognitive comorbidities. In a genetic model of absence epilepsy in the rat, the GAERS, we showed that spike-and-wave discharges are initiated in the barrel field primary somatosensory cortex that codes whisker-related information therefore playing an essential role in rodents' interactions with their environment. Sensory-information processing is impaired in the epileptic barrel field primary somatosensory cortex of GAERS with a delayed sensory-evoked potential and a duplicated neuronal response to whisker-stimulation in in vivo extracellular recordings.

[Christmas article. The influence of lunar phases on epilectic seizures].

Ugeskr Laeger 2018 Dec;180(50)

An old myth asserts, that the lunar phases influence epileptic seizures. This Christmas article examines the assertion by reviewing four articles about the correlation between the lunar phases and the frequency of seizures in patients with epilepsy and in patients with non-epileptic seizures. Hypotheses suggest, that sleep disturbances, melatonin level and nocturnal illumination may play a role in the relation between lunar phases and epileptic seizures. Read More
