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.

Diaper changing-induced reflex seizures in CDKL5-related epilepsy.

Epileptic Disord 2018 10;20(5):428-433

Child Neuropsychiatry, Department of Surgical Sciences, Dentistry, Gynecology and Pediatrics, University of Verona.

Mutations in the CDKL5 (cyclin-dependent kinase-like-5) gene are known to determine early-onset drug resistant epilepsies and severe cognitive impairment with absent language, hand stereotypies, and deceleration of head growth. Reflex seizures are epileptic events triggered by specific stimuli and diaper changing is a very rare triggering event, previously described in individual cases of both focal and unclassified epilepsy, as well as in Dravet syndrome. Our aim was to describe diaper changing-induced reflex seizures as one of the presenting features in a case of CDKL5-related epilepsy, providing video-EEG documentation and focusing discussion on hyperexcitability determined by the disease.

[Tips for taking the medical history in patients with syncope].

Authors:
Carsten W Israel

Herzschrittmacherther Elektrophysiol 2018 Jun;29(2):144-154

Klinik für Innere Medizin - Kardiologie, Diabetologie & Nephrologie, Evangelisches Klinikum Bethel, Burgsteig 13, 33617, Bielefeld, Deutschland.

Transient loss of consciousness represents one of the most frequent reasons for patients to present in the emergency room. Already at the very beginning, the diagnostic work-up is faced with fundamental questions: (1) Was it really a loss of consciousness? (2) Which department (neurology, cardiology, or others) should check the patient? (3) Is an in-hospital diagnostic work-up required? These questions can be answered from a meticulous patient history which needs to be adjusted to the individual case but also has to systematically go through a list of questions. Patient history has to clarify whether syncope was present. Read More

BMJ Case Rep 2018 May 8;2018. Epub 2018 May 8.

Department of Internal Medicine, Allegiance Health, Jackson, Michigan, USA.

Reflex anoxic seizures (RAS) are essential in the differential diagnosis of non-epileptic paroxysmal seizures. They are precipitated by vagally mediated brief cardiac asystole, which in turn leads to transient cerebral ischaemia. RAS are usually seen in infants and preschool children, but in this case happened in a middle-aged man. Read More

Clinical and electrographic features of sunflower syndrome.

Epilepsy Res 2018 05 3;142:58-63. Epub 2018 Mar 3.

Stanford University School of Medicine, Department of Neurology, Division of Child Neurology, United States. Electronic address:

Background: Sunflower Syndrome describes reflex seizures - typically eyelid myoclonia with or without absence seizures - triggered when patients wave their hands in front of the sun. While valproate has been recognized as the best treatment for photosensitive epilepsy, many clinicians now initially treat with newer medications; the efficacy of these medications in Sunflower Syndrome has not been investigated. We reviewed all cases of Sunflower Syndrome seen at our institution over 15 years to describe the clinical course, electroencephalogram (EEG), and treatment response in these patients. Read More

Audiogenic Epilepsy and Structural Features of Superior Colliculus in KM Rats.

Dokl Biochem Biophys 2018 Jan 14;478(1):47-49. Epub 2018 Mar 14.

Institute of Gene Biology, Russian Academy of Sciences, Moscow, 119334, Russia.

Using immunoblotting, we showed that in rats of audiogenic epilepsy (AE) prone strain (Krushinsky- Molodkina, KM) the superior colliculus tissue (SC) contains significantly less quantity of glial neurotrophic factor (GDNF), beta-tubulin and actin in comparison to the same brain region in "0" rats, nonprone to AE. This fact led to the suggestion that the histological structure of the SC in KM rats could differ significantly from that of the "0" strain. Using neuromorphologу technique, we demonstrated that the total number of SC cells, as well as the number of neurons were significantly less in KM rats than in the "0" strain rats. Read More

Effects of vibration-induced fatigue on the H-reflex.

J Electromyogr Kinesiol 2018 Apr 15;39:134-141. Epub 2018 Feb 15.

Eindhoven University of Technology, Eindhoven, The Netherlands.

Vibration exercise (VE) has been suggested as an effective training for improving muscle strength and coordination. However, the underlying physiological adaptation processes are not yet fully understood, limiting the development of safe and effective exercise protocols. To better understand the neuromuscular responses elicited by VE, we aimed at investigating the acute effects of superimposed vibration on the Hoffmann reflex (H-reflex), measured after fatiguing exercise.

Intractable Yawning as a Predominant Symptom of Temporal Lobe Ganglioglioma: Case Report and Review of Literature.

Asian J Neurosurg 2018 Jan-Mar;13(1):102-104

Department of Neurosurgery, Government Medical College, Calicut, Kerala, India.

Yawning, a physiologic reflex exhibited by vertebrates, is seldom noticed as a symptom of a disease. Not too often is a patient aware of it as a symptom, unless it is of such a distressing nature to seek attention. In this situation, to distinguish between normal and abnormal behavior would pose a diagnostic dilemma for the attending physician. Read More

Somatosensory reflex epilepsy: simultaneous video-EEG monitoring and surface EMG.

Epileptic Disord 2018 Feb;20(1):70-72

Samsung Medical Center, Sungkyunkwan University School of Medicine - Neurology, Seoul, Republic of Korea.

Somatosensory reflex epilepsy is induced by repetitive cutaneous contact of a circumscribed body area with a tight time-lock between somatosensory stimulation and seizure. We describe the case of a 27-year-old man with seizures induced by repetitive tapping on the sole of the right foot. Simultaneous video-EEG monitoring and surface electromyography was performed during a seizure triggered by repetitive tapping on the right sole aspect using a hammer. Read More

Reflex epilepsy: triggers and management strategies.

Neuropsychiatr Dis Treat 2018 18;14:327-337. Epub 2018 Jan 18.

Department of Neurology and Clinical Neurophysiology, Cerrahpasa Faculty of Medicine, University of Istanbul, Istanbul, Turkey.

Reflex epilepsies (REs) are identified as epileptic seizures that are consistently induced by identifiable and objective-specific triggers, which may be an afferent stimulus or by the patient's own activity. RE may have different subtypes depending on the stimulus characteristic. There are significant clinical and electrophysiologic differences between different RE types. Read More

Delayed myelination and neurodevelopment in male seizure-prone versus seizure-resistant rats.

Epilepsia 2018 04 28;59(4):753-764. Epub 2018 Jan 28.

Department of Medicine, University of Melbourne, Royal Melbourne Hospital, Parkville, Vic., Australia.

Objective: Aberrant myelination and developmental delay have been reported in epilepsy. However, it is unclear whether these are linked to intrinsic mechanisms that support a predisposition toward seizures and the development of epilepsy. Thus, we compared rates of myelination and neurodevelopment in male rats selectively bred for enhanced susceptibility to kindling epileptogenesis (FAST) with male rats bred for resistance (SLOW).

Neuronal activity organization features in human consciousness: summary of introductory remarks in a dialogue with neurological surgery residents.

Neurocase 2018 Feb 9;24(1):7-9. Epub 2018 Jan 9.

c Department of Neurological Surgery, Center for Neuromodulation , Ohio State University Wexner Medical Center , Columbus , OH , USA.

Agreeing with Damasio's statement defining the "process" of consciousness, we propose the self as created by mind-based knowledge and a combination of images of an organism's intentional motor responses interacting with its environment. The lemniscal system, with plastic capabilities, manages gravity in voluntary movement. The spinal segment motor reflex represents the schema of gravity-managing neuronal activity, and it can become "nested" in cortical areas participating in consciousness-building, allowing consideration of the brain as a hyper-evolved nervous system segment harboring atavic spinal organization.

Does Valproic Acid/Na Valproate Suppress Auditory Startle Reflex in Patients With Epilepsy?

Clin EEG Neurosci 2018 Nov 20;49(6):407-413. Epub 2017 Dec 20.

1 Cerrahpaşa School of Medicine, Istanbul University, Istanbul, Turkey.

Background And Objective: Auditory startle response (ASR) was normal in juvenile myoclonic epilepsy whereas it was suppressed in progressive myoclonic epilepsy. However, both groups were using valproic acid/Na valproate (VPA) in different doses. Therefore, we aimed to analyze whether VPA has an impact on ASR in a cohort of epilepsy. Read More

Yawning-Its anatomy, chemistry, role, and pathological considerations.

Prog Neurobiol 2018 02 29;161:61-78. Epub 2017 Nov 29.

20 Rue de Chartres, 28160 Brou, France.

Yawning is a clinical sign of the activity of various supra- and infratentorial brain regions including the putative brainstem motor pattern, hypothalamic paraventricular nucleus, probably the insula and limbic structures that are interconnected via a fiber network. This interaction can be seen in analogy to other cerebral functions arising from a network or zone such as language. Within this network, yawning fulfills its function in a stereotype, reflex-like manner; a phylogenetically old function, preserved across species barriers, with the purpose of arousal, communication, and maybe other functions including respiration.

Analysis of ERK1/2 kinases in the inferior colliculus of rats genetically prone to audiogenic seizures during postnatal development.

Dokl Biochem Biophys 2017 Sep 4;476(1):296-298. Epub 2017 Nov 4.

Sechenov Institute of Evolutionary Physiology and Biochemistry, Russian Academy of Sciences, St. Petersburg, 194223, Russia.

The activity of ERK1/2 kinases in the quadrigemina inferior colliculus of Krushinsky-Molodkina rats of different age, which are characterized by an increased seizure readiness compared to Wistar rats, was analyzed. An increased (probably genetically determined) activity of these enzymes during the development of epileptiform activity in ontogeny was found, which may be the cause of abnormalities in the neurotransmitter system functioning.

Electroencephalography in the Diagnosis of Genetic Generalized Epilepsy Syndromes.

Front Neurol 2017 25;8:499. Epub 2017 Sep 25.

Department of Medicine, St. Vincent's Hospital, The University of Melbourne, Melbourne, VIC, Australia.

Genetic generalized epilepsy (GGE) consists of several syndromes diagnosed and classified on the basis of clinical features and electroencephalographic (EEG) abnormalities. The main EEG feature of GGE is bilateral, synchronous, symmetric, and generalized spike-wave complex. Other classic EEG abnormalities are polyspikes, epileptiform K-complexes and sleep spindles, polyspike-wave discharges, occipital intermittent rhythmic delta activity, eye-closure sensitivity, fixation-off sensitivity, and photoparoxysmal response.
