First the spacecraft New Horizons travelled three billion miles to send back images from Pluto, the last unexplored major body in our solar system. The excitement of scientists at NASA rippled around the world. Closer to home, there were ripples of excitement on a smaller, but still significant scale, as research into the three billion bases that make up our DNA, shone a light on the genetics of epilepsy. While space exploration reveals the secrets It’s a jigsaw where we don’t even know of a world at the far edge of our solar system, how many pieces will be in the final picture. epilepsy research is beginning to reveal the Our research is ongoing and you can help us secrets deep within our DNA, secrets that are to shape the direction it will follow by taking slowly helping to identify the causes of epilepsy. part in our online research survey.

  • Therapeutic Class Overview Anticonvulsants

    Therapeutic Class Overview Anticonvulsants

    Therapeutic Class Overview Anticonvulsants INTRODUCTION Epilepsy is a disease of the brain defined by any of the following (Fisher et al 2014): ○ At least 2 unprovoked (or reflex) seizures occurring > 24 hours apart; ○ 1 unprovoked (or reflex) seizure and a probability of further seizures similar to the general recurrence risk (at least 60%) after 2 unprovoked seizures, occurring over the next 10 years; ○ Diagnosis of an epilepsy syndrome. Types of seizures include generalized seizures, focal (partial) seizures, and status epilepticus (Centers for Disease Control and Prevention [CDC] 2018, Epilepsy Foundation 2016). ○ Generalized seizures affect both sides of the brain and include: . Tonic-clonic (grand mal): begin with stiffening of the limbs, followed by jerking of the limbs and face . Myoclonic: characterized by rapid, brief contractions of body muscles, usually on both sides of the body at the same time . Atonic: characterized by abrupt loss of muscle tone; they are also called drop attacks or akinetic seizures and can result in injury due to falls . Absence (petit mal): characterized by brief lapses of awareness, sometimes with staring, that begin and end abruptly; they are more common in children than adults and may be accompanied by brief myoclonic jerking of the eyelids or facial muscles, a loss of muscle tone, or automatisms. ○ Focal seizures are located in just 1 area of the brain and include: . Simple: affect a small part of the brain; can affect movement, sensations, and emotion, without a loss of consciousness . Complex: affect a larger area of the brain than simple focal seizures and the patient loses awareness; episodes typically begin with a blank stare, followed by chewing movements, picking at or fumbling with clothing, mumbling, and performing repeated unorganized movements or wandering; they may also be called “temporal lobe epilepsy” or “psychomotor epilepsy” .

QUALITATIVE AND QUANTITATIVE COMPOSITION One tablet contains: Active substance: Imepitoin 100 mg Imepitoin 400 mg For the full list of excipients, see section 6.1. 3. PHARMACEUTICAL FORM Tablets White, oblong, half-scored tablets with embedded logo “I 01” (100 mg) or “I 02” (400 mg) on one side. The tablet can be divided into equal halves. 4. CLINICAL PARTICULARS 4.1 Target species Dog 4.2 Indications for use, specifying the target species For the reduction of the frequency of generalised seizures due to idiopathic epilepsy in dogs for use after careful evaluation of alternative treatment options. 4.3 Contraindications Do not use in case of hypersensitivity to the active substance or to any of the excipients. Do not use in dogs with severely impaired hepatic function, severe renal or severe cardiovascular disorders (see section 4.7). 4.4 Special warnings The pharmacological response to imepitoin may vary and efficacy may not be complete. Nevertheless imepitoin is considered to be a suitable treatment option in some dogs because of its safety profile (see section 5.1). On treatment, some dogs will be free of seizures, in other dogs a reduction of the number of seizures will be observed, whilst others may be non-responders. In non-responders, an increase in seizure frequency may be observed. Should seizures not be adequately controlled, further diagnostic measures and other antiepileptic treatment should be considered. The benefit/risk assessment for the individual dog should take into account the details in the product literature.

    International Bureau for Epilepsy Annual Report 2003 Setting the Standard From Our Vision IBE has a vision of the world where everywhere ignorance and fear about epilepsy are replaced by understanding and care. Our Mission IBE exists to improve the social condition and quality of life of people with epilepsy and those who care for them. Our Goals • ORGANISATION To provide an international umbrella organisation for national epilepsy organisations whose primary purpose is to improve the social condition and quality of life of people with epilepsy and those who care for them. • SUPPORT To provide a strong global network to support the development of new Chapters, to support existing Chapters to develop to their fullest potential and to encourage co-operation and contact between Chapters. • COMMUNICATION To promote the facts about epilepsy and to communicate IBE’s vision, mission and messages to the widest possible audience. • EDUCATION To increase understanding and knowledge of epilepsy. • REPRESENTATION To provide an international and global platform for the representation of epilepsy. 2 International Bureau for Epilepsy Foreward During my fifteen years working, first in the British Parliament and Government and now in the European Parliament, I have seen and welcomed an ever-increasing awareness of the importance and benefits of strong partnerships. Networks and alliances are more than just “buzz words” – they are proven methods of achieving desired goals. They may not be easy to achieve, but, once in place, they make it simpler for patients, carers, professionals and academics to explain health needs and options for action and they make it easier for policy-makers to listen and to understand what is needed.

    Idiopathic Epilepsy in Dogs – Part One: Patient Approach

    Vet Times The website for the veterinary profession https://www.vettimes.co.uk Idiopathic epilepsy in dogs – part one: patient approach Author : Jacques Penderis, Holger Volk Categories : Vets Date : February 9, 2015 Dogs with recurrent epileptic seizures, and where no interictal neurological deficits or abnormalities on routine diagnostic tests are evident, have traditionally been defined as having “idiopathic epilepsy”. Rather than being a specific, single diagnosis, it is probable idiopathic epilepsy represents a complex interplay between genetic predisposition and intrinsic and extrinsic environmental factors, and the term “presumed genetic” has also been suggested to define these patients. A genetic basis for idiopathic epilepsy has been proposed in a number of breeds, including the golden retriever, Labrador retriever, Bernese mountain dog, Irish wolfhound, English springer spaniel, Keeshond, Hungarian vizsla, standard poodle, border collie and Finnish spitz (Viitmaa et al, 2013) and a possible susceptibility locus for epileptic seizures has been characterised in the Belgian shepherd dog (Seppälä et al, 2012). Reflecting its importance in veterinary medicine, idiopathic epilepsy is reported as the most common chronic neurological disease in dogs, with a prevalence of around 0.6 per cent in first opinion practice. Generalised seizures (where there is impairment of consciousness) are the most common type of epileptic seizure in dogs, while partial seizures appear to be relatively more common in cats; this, in part, represents the tendency for dogs with idiopathic epilepsy to have generalised seizures, or focal seizures with rapid secondary generalisation. The accurate description of generalised seizures in a patient with suspected idiopathic epilepsy is important, firstly to differentiate the episodes from other causes of collapse (for example, syncope) and secondly because the presence of generalised seizures is one of the criteria for making a diagnosis of idiopathic epilepsy.
  • Best Practice Guidelines for Training

    Best Practice Guidelines for Training

    Best practice guidelines for training professional carers in the administration of Buccal (Oromucosal) Midazolam for the treatment of prolonged and / or clusters of epileptic seizures in the community Safe & Effective | Kind & Caring | Exceeding Expectation Epilepsy Nurses Association (ESNA) June 2019 1. Foreword One of the most important components of epilepsy care is the pre-hospital community management of prolonged or repeated seizures, which, if untreated, can increase the risk of status epilepticus. Convulsive status epilepticus is a medical emergency requiring admission to hospital and has a mortality rate of up to 20 per cent. Effective management of seizures in the community in people at high risk of status epilepticus could significantly reduce mortality, morbidity and emergency health care utilisation. The Joint Epilepsy Council issued guidance until it was disbanded in 2015, leaving a vacuum in the review and update of clinical guidelines. Unfortunately, the clinical processes ensuring the safety and consistency of buccal midazolam usage demonstrates considerable heterogeneity. There are no current guidelines, standards or pathways to ensure the safety of all involved in the process i.e. patient, carer or professional. ESNA is an organisation principally formed by nurses with an interest in epilepsy. Most ESNA members support or complete training for buccal midazolam to ensure core competencies are up to date and patient safety is protected. ESNA is joined by the International League Against Epilepsy (British Chapter) and the Royal College of Psychiatrists (ID Faculty) as the other principal specialist clinical stakeholders with an interest to ensure governance in this complex care area is addressed robustly. ESNA has collaborated with the ILAE and the Royal College of Psychiatrists to produce updated buccal midazolam guidance.
