Wilder Penfield and the vascular hypothesis of focal epilepsy.

Authors:
Richard Leblanc

J Neurosurg 2019 Jan 4:1-7. Epub 2019 Jan 4.

The vascular hypothesis held that posttraumatic epilepsy results from reflex vasoconstriction of cortical arteries around a cerebral scar. Penfield's initial support and eventual refutation of the vascular hypothesis is the subject of this paper, which is based on a review of his clinical charts, operative and electrocorticographic reports, and brain maps held in the Montreal Neurological Institute archives. Penfield and his collaborators discovered that posttraumatic cortical scars are composed of astro-glial fibers, collagen fibrils, and a neo-vascular plexus that anastomoses with the surrounding cortical arteries.

Electronic address:

Seizures are commonly thought to occur in a spontaneous, unpredictable manner. However, it is well-established that a subset of patients with epilepsy can experience reflex seizures that are consistently elicited by a specific stimulus. While various forms of reflex epilepsy have been documented in the literature, acute affective states have not been commonly described as a potential reflex seizure trigger. Read More

Diving responses elicited by nasopharyngeal irrigation mimic seizure-associated central apneic episodes in a rat model.

Neurobiol Dis 2019 Apr 25;124:408-415. Epub 2018 Dec 25.

Departments of Physiology & Pharmacology, SUNY Downstate Medical Center, Brooklyn, NY, USA; Neurology, SUNY Downstate Medical Center, Brooklyn, NY, USA. Electronic address:

The spread of epileptic seizure activity to brainstem respiratory and autonomic regions can elicit episodes of obstructive apnea and of central apnea with significant oxygen desaturation and bradycardia. Previously, we argued that central apneic events were not consequences of respiratory or autonomic activity failure, but rather an active brainstem behavior equivalent to the diving response resulting from seizure spread. To test the similarities of spontaneous seizure-associated central apneic episodes to evoked diving responses, we used nasopharyngeal irrigation with either cold water or mist for 10 or 60 s to elicit the diving response in urethane-anesthetized animals with or without kainic acid-induced seizure activity.

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.

POSSIBLE IMPLEMENTATION OF GABAERGIC AND GLUTAMATERGIC SYSTEMS IN REALIZATION OF ANTIEPILEPTIC EFFECTS OF ACOUSTIC RANGE ELECTRO - MAGNETIC FIELDS.

Georgian Med News 2018 Jul-Aug(280-281):112-116

LEPL Beritashvili Center of Experimental Biomedicine, Tbilisi; I. Javakhishvili Tbilisi State University, Tbilisi, Georgia.

Seizure is a clinical manifestation of a hyperexcitable neuronal network, in which, the electrical balance underlying the normal neuronal activity is altered pathologically-excitation (Glutamatergic activity) predominates over inhibition (GABAergic activity). Arresting of seizure activity is carried out by restoration of neurotransmitter balance. This process has a direct relation with ion channel permeability in cell and ion transmembrane movement.

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

Reflex anoxic seizures (RAS) in an adult patient: a separate entity from epilepsy.

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

Tap seizures in infancy: A critical review.

Seizure 2018 Jul 23;59:11-15. Epub 2018 Apr 23.

Child Neuropsychiatric Unit, Neuroscience Department, University of Parma, Parma, Italy.

Tap seizure is a type of reflex myoclonic epilepsy in which seizures are evoked mainly by unexpected tactile stimuli and which is classified among the electroclinical syndromes of infancy. This condition, whose onset is in the first two years of life, is characterized by excellent prognosis and is extremely rare. We reviewed all published articles and case reports on Reflex Myoclonic Epilepsies focusing on touch-induced seizures in order to clarify clinical and electroencephalographic findings. Read More

Consensus Paper: Neurophysiological Assessments of Ataxias in Daily Practice.

Cerebellum 2018 Oct;17(5):628-653

Department of Neurology, Essen University Hospital, University of Duisburg-Essen, Essen, Germany.

The purpose of this consensus paper is to review electrophysiological abnormalities and to provide a guideline of neurophysiological assessments in cerebellar ataxias. All authors agree that standard electrophysiological methods should be systematically applied in all cases of ataxia to reveal accompanying peripheral neuropathy, the involvement of the dorsal columns, pyramidal tracts and the brainstem. Electroencephalography should also be considered, although findings are frequently non-specific. Read More

Central Regulation of Micturition and Its Association With Epilepsy.

Int Neurourol J 2018 Mar 28;22(1):2-8. Epub 2018 Mar 28.

Department of Pharmacology, The Catholic Neuroscience Institute, College of Medicine, The Catholic University of Korea, Seoul, Korea.

Micturition is a complex process involving the bladder, spinal cord, and the brain. Highly sophisticated central neural program controls bladder function by utilizing multiple brain regions, including pons and suprapontine structures. Periaqueductal grey, insula, anterior cingulate cortex, and medial prefrontal cortex are components of suprapontine micturition centers. Read More

Weird Laughing in Hyperekplexia: A new phenotype associated with a novel mutation in the GLRA1 gene?

Seizure 2018 May 20;58:6-8. Epub 2018 Mar 20.

Department of Neurology, The First Affiliated Hospital of Zhengzhou University, Zhengzhou, Henan Province, 450052, People's Republic of China.

Hyperekplexia (HPX) or startle disease is a rare hereditary neurological disorder characterized by generalized stiffness, excessive startle reflex to unexpected stimuli and a short period of generalized stiffness following the startle response, and can be complicated by umbilical or inguinal hernia, developmental delay and apnea spell. HPX is caused mainly by mutations in the GLRA1 gene, and has a good response to clonazepam. In this short communication we describe an 11-year-old girl with excessive startle reflex, weird laughing and developmental delay since early infancy. Read More

Expert Rev Neurother 2018 04 27;18(4):275-287. Epub 2018 Mar 27.

b Danish Epilepsy Centre , Dianalund , Denmark.

Introduction: There is growing awareness that reflex epileptic seizures offer unique insight into natural seizure generation in humans. In the last years, focus has mostly been on reflex seizures in generalized epilepsies whereas a comprehensive review of their role in focal epilepsies has been missing. Areas covered: This paper reviews reflex seizures strictly in focal epilepsies, not including focal reflex seizures in system epilepsies that also exist. 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
