References Last updated: July 7, 2019 Owners: Danielle Hirsch, MD, Emergency Medicine; Jennifer Avallone, DO, Neurology This pathway is intended as a guide for physicians, physician assistants, nurse practitioners and other healthcare providers. It should be adapted to the care of specific patient based on the patient’s individualized circumstances and the practitioner’s professional judgment. 2 Johns Hopkins All Children's Hospital Status Epilepticus Clinical Pathway Rationale This clinical pathway was developed by a consensus group of JHACH neurologists/epileptologists, emergency physicians, advanced practice providers, hospitalists, intensivists, nurses, and pharmacists to standardize the management of children treated for status epilepticus. The following clinical issues are addressed: ● When to evaluate for status epilepticus ● When to consider admission for further evaluation and treatment of status epilepticus ● When to consult Neurology, Hospitalists, or Critical Care Team for further management of status epilepticus ● When to obtain further neuroimaging for status epilepticus ● What ongoing therapy patients should receive for status epilepticus Background: Status epilepticus (SE) is the most common neurological emergency in children1 and has the potential to cause substantial morbidity and mortality. Incidence among children ranges from 17 to 23 per 100,000 annually.2 Prevalence is highest in pediatric patients from zero to four years of age.3 Ng3 acknowledges the most current definition of SE as a continuous seizure lasting more than five minutes or two or more distinct seizures without regaining awareness in between. -
Non-Epileptic Seizures a Short Guide for Patients and Families
Non-epileptic seizures a short guide for patients and families Department of Neurology Information for patients Royal Hallamshire Hospital What are non-epileptic seizures? In a seizure people lose control of their body, often causing shaking or other movements of arms and legs, blacking out, or both. Seizures can happen for different reasons. During epileptic seizures, the brain produces electrical impulses, which stop it from working normally. Non-epileptic seizures look a little like epileptic seizures, but are not caused by abnormal electrical activity in the brain. Non-epileptic seizures happen because of problems with handling thoughts, memories, emotions or sensations in the brain. Such problems are sometimes related to stress. However, they can also occur in people who seem calm and relaxed. Often people do not understand why they have developed non-epileptic seizures. Are non-epileptic seizures rare? For every 100,000 people, between 15 and 30 have non- epileptic seizures. Nearly half of all people brought in to hospital with suspected serious epilepsy turn out to have non- epileptic seizures instead. One of the reasons why you may not have heard of non- epileptic seizures is that there are several other names for the same problem. Non-epileptic seizures are also known as pseudoseizures, psychogenic, dissociative or functional seizures. Sometimes people who have non-epileptic seizures are told that they suffer from non-epileptic attack disorder (NEAD). How can I be sure that this is the right diagnosis? Non-epileptic seizures often look like epileptic seizures to friends, family members and even doctors. Like epilepsy, non- epileptic seizures can cause injuries and loss of control over bladder function. -

Myoclonic Status Epilepticus in Juvenile Myoclonic Epilepsy
Original article Epileptic Disord 2009; 11 (4): 309-14 Myoclonic status epilepticus in juvenile myoclonic epilepsy Julia Larch, Iris Unterberger, Gerhard Bauer, Johannes Reichsoellner, Giorgi Kuchukhidze, Eugen Trinka Department of Neurology, Medical University of Innsbruck, Austria Received April 9, 2009; Accepted November 18, 2009 ABSTRACT – Background. Myoclonic status epilepticus (MSE) is rarely found in juvenile myoclonic epilepsy (JME) and its clinical features are not well described. We aimed to analyze MSE incidence, precipitating factors and clini- cal course by studying patients with JME from a large outpatient epilepsy clinic. Methods. We retrospectively screened all patients with JME treated at the Department of Neurology, Medical University of Innsbruck, Austria between 1970 and 2007 for a history of MSE. We analyzed age, sex, age at seizure onset, seizure types, EEG, MRI/CT findings and response to antiepileptic drugs. Results. Seven patients (five women, two men; median age at time of MSE 31 years; range 17-73) with MSE out of a total of 247 patients with JME were identi- fied. The median follow-up time was seven years (range 0-35), the incidence was 3.2/1,000 patient years. Median duration of epilepsy before MSE was 26 years (range 10-58). We identified three subtypes: 1) MSE with myoclonic seizures only in two patients, 2) MSE with generalized tonic clonic seizures in three, and 3) generalized tonic clonic seizures with myoclonic absence status in two patients. All patients responded promptly to benzodiazepines. One patient had repeated episodes of MSE. Precipitating events were identified in all but one patient. Drug withdrawal was identified in four patients, one of whom had additional sleep deprivation and alcohol intake. -

Hande CAĞLAYAN, Ph.D. 2International Biomedicine and Genome Center, Dokuz Eylül University, İzmir, Turkey Summary Lafora Disease (LD) is a fatal neurodegenerative condition characterized by the accumulation of abnormal glycogen inclusions known as Lafora bodies (LBs). Patients with LD manifest myoclonus and tonic-clonic seizures, visual hallucinations, and progressive neurological deteri- oration beginning at the age of 8-18 years. Mutations in either EPM2A gene encoding protein phosphatase laforin or NHLRC1 gene encoding ubiquitin-ligase malin cause LD. Approximately, 200 distinct mutations accounting for the disease are listed in the Lafora progressive my- oclonus epilepsy mutation and polymorphism database. In this review, the genotype-phenotype correlations, the genetic diagnosis of LD, the downregulation of glycogen metabolism as the main cause of LD pathogenesis and the regulation of glycogen synthesis as a key target for the treatment of LD are discussed. Key words: EPM2A and NHLRC1 gene mutations; genotype-phenotype relationship; Lafora progressive myoclonus epilepsy; LD pathogenesis.
