Sodium valproate is a commonly used antiseizure drug with broad indications for different seizuretypes and epilepsy syndromes. Well-recognised side effects include weight gain, tremor, dizziness, and unsteadiness. Non-hyperammonaemic parkinsonism, with or without cognitive impairment, is a rare adverse effect of sodium valproate. We present the case of a sixty year-old lady with a generalized seizure disorder, treated with phenytoin, valproate, lamotrigine and clonazepam. Following withdrawal of phenytoin she developed an akinetic-rigid syndrome, with ataxia and marked cognitive impairment...

INTRODUCTION: Resistance to treatments is a common feature of Ohtahara, Aicardi, West and Dravet syndromes, as well as malignant migrating epilepsy in infancy. AIMS: To update the therapeutic management and to analyse whether the aetiology somehow determines the treatment. DEVELOPMENT: Convulsive seizures in the first year of life may be due to a potentially treatable aetiology, which makes it essential to carry out a complete evaluation so as to be able to begin, as early as possible, the most suitable and the non-specific symptomatic treatments to control the seizures, which prevents or minimises their deleterious effects...

OBJECTIVE: The mouse 6 Hz model of psychomotor seizures is a well-established and commonly used preclinical model for antiseizure drug (ASD) discovery. Despite its widespread use both in the identification and differentiation of novel ASDs in mice, a corresponding assay in rats has not been developed. We established a method for 6 Hz seizure induction in rats, with seizure behaviors similar to those observed in mice including head nod, jaw clonus, and forelimb clonus. METHODS: A convulsive current that elicits these seizure behaviors in 97% of rats (CC97 ) was determined using a Probit analysis...

INTRODUCTION: Early myoclonus after cardiac arrest (CA) is traditionally viewed as a poor prognostic sign (status myoclonus). However, some patients may present early Lance-Adams syndrome (LAS): under appropriate treatment, they can reach a satisfactory functional outcome. Our aim was to describe their profile, focusing on pharmacologic management in the ICU, time to return of awareness, and long-term prognosis. METHODS: Adults with early LAS (defined as generalized myoclonus within 96h, with epileptiform EEG within 48h after CA) were retrospectively identified in our CA registry between 2006 and 2016...

OBJECTIVES: West syndrome (also known as infantile spasm because of its main seizure type) is a rare form of epilepsy that begins during early infancy. Recent guidelines and reviews on West syndrome recommend the use of adrenocorticotropic hormone steroids, or vigabatrin, as the first-line treatment. However, West syndrome remains to be one of the most challenging epilepsies to treat. Here, we systematically reviewed the current literature obtained during the previous decade. This article provides an overview of the current treatment of infantile spasms...

Transcranial alternating current stimulation (tACS) is a re-emergent neuromodulation technique that consists in the external application of oscillating electrical currents that induces changes in cortical excitability. We present the case of a 16-year-old female with pharmaco-resistant juvenile myoclonic epilepsy to 3 antiepileptic's drugs characterized by 4 myoclonic and 20 absence seizures monthly. She received tACS at 1 mA at 3 Hz pulse train during 60 min over Fp1-Fp2 (10-20 EEG international system position) during 4 consecutive days using an Endeavor™ IOM Systems device(®) (Natus Medical Incorporated, Middleton, WI, USA)...

PURPOSE: Status epilepticus (SE) requires not only urgent symptomatic treatment with antiepileptic drugs but also rapid identification and treatment of its cause. This narrative review summarizes the most important advances in classification and treatment of SE. METHOD: Data sources included MEDLINE, EMBASE, ClinicalTrials.gov, and back tracking of references in pertinent studies, reviews, and books. RESULTS: SE is now defined as "a condition resulting either from the failure of the mechanisms responsible for seizure termination or from the initiation of mechanisms, which lead to abnormally, prolonged seizures (after time point t1)...

BACKGROUND: Cytisine (CYT) is a partial agonist of brain α4β2 nicotinic acetylcholine receptors widely used in Central/Eastern Europe for smoking cessation. OBJECTIVES: This study evaluated the effect of CYT on the ability of classical and novel antiepileptic drugs to prevent seizures evoked by the 6-Hz test, a model of psychomotor seizures in mice thought as a model of drug-resistant seizures. RESULTS: CYT administered intraperitoneally (i...

Generalized motor seizures, usually tonic-clonic, tonic-vibratory, myoclonic or clonic, and stimulus-sensitive/action myoclonus are typical features of progressive myoclonus epilepsies (PMEs). Despite the introduction of many anticonvulsants, the treatment of these symptoms, particularly myoclonus, remains challenging, due to the incomplete and often transitory effects of most drugs. Moreover, treatment is only symptomatic, since therapy targeting the underlying aetiology for these genetic conditions is in its infancy...

BACKGROUND: Drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome is a rare and potentially life-threatening acute drug-induced hypersensitivity reaction. Antiepileptic drugs (AEDs) predominantly aromatic AEDs are commonly reported in DRESS. To date there are no reports of sulthiame AED causing DRESS syndrome. METHOD: We report a 10-year-old girl of Indian descent with AED resistant epilepsy on maintenance sodium valproate and clonazepam. Sulthiame AED was initiated to try to improve her seizure control...

Edward C Lauterbach
Anxiety is common in the Mild Cognitive Impairment (MCI) stage of Alzheimer's disease (AD) and the pre-motor stages of Parkinson's disease (PD). A concomitant and possible cause of this anxiety is microglial activation, also considered a key promoter of neurodegeneration in MCI and early PD via inflammatory mechanisms and the generation of degenerative proinflammatory cytokines. Psychiatric disorders, prevalent in AD and PD, are often treated with psychiatric drugs (psychotropics), raising the question of whether psychotropics might therapeutically affect microglial activation, MCI, and PD...

REVIEW
Ariel Levy, Robert Chen
Treatment of myoclonus requires an understanding of the physiopathology of the condition. The first step in treatment is to determine if there is an epileptic component to the myoclonus and treat accordingly. Secondly, a review of medications (e.g., opiates) and comorbidities (e.g., hepatic or renal failure) is required to establish the possibility of iatrogenic and reversible conditions. Once those are eliminated, delineation between cortical, cortico-subcortical, subcortical, brainstem, and spinal generators can determine the first-line treatment...

BACKGROUND: Levetiracetam-induced rage is a rare neurobehavioral adverse effect of levetiracetam that is characterized by seething rage, uncontrollable anger, fits of fury, depression, violence, and suicidal tendencies. It occurs more in patients with prior mood or psychotic disturbances. No such case has been reported in Nigeria. METHOD: We report two cases of levetiracetam-induced rage. The first patient was a 29-year-old male with a 14-year history of intractable posttraumatic epilepsy...

BACKGROUND: The incidence rate of depression among patients with epilepsy is relatively high. The basis of proper therapy is knowledge of drug interactions, which may enable to maximize therapeutic effects and minimize undesired effects of the combined treatment. The purpose of this study was to evaluate the influence of reboxetine, a selective norepinephrine reuptake inhibitor, on the seizure threshold and anticonvulsant effects of four classic antiepileptic drugs: valproate, phenobarbital, ethosuximide, and clonazepam...

UNLABELLED: Proper treatment of hypoxic myoclonic status is not clearly determined. Induced hypothermia is improving prognosis and a more aggressive treatment might be beneficial in some patients. Among the new options of antiepileptic drugs, perampanel (PER) is a drug with a novel mechanism, and it might be a promising drug for myoclonic status or as an antimyoclonic drug. We describe the use of PER in one patient with hypoxic super-refractory myoclonic status. DESCRIPTION: A 51-year-old patient presented after an out-of-hospital cardiac arrest due to an acute myocardial infarction...

We report a 4-year-old boy with generalized seizures with abrupt falling and unresponsive staring provoked by somatosensory stimuli of the face. Ictal manifestation comprised a sudden fall immediately after wiping the face, followed by unresponsive staring for around 10 seconds, during which time the video-EEG recorded paroxysmal 3-Hz diffuse spike-wave complexes, which were followed by high-voltage 3.5 to 4-Hz delta wave discharges, predominantly appearing in the bilateral frontal areas. Seizures were not controlled by clonazepam, valproate or levetiracetam, but were successfully treated with lamotrigine added to valproate...

OBJECTIVE: Evaluation of the efficacy of antiepileptic drugs (AEDs) used in the treatment of Dravet syndrome (DS) with different genotypes. METHODS: Patients with DS were recruited from different tertiary hospitals. Using a direct sequencing method and Multiplex Ligation-Dependent Probe Amplification (MLPA), genetic abnormalities were assessed within the exons and flanking introns of SCN1A gene, which encodes the α1 subunit of neuronal sodium channels. Patients were divided into SCN1A-positive and SCN1A-negative groups according to the results of genetic tests...

BACKGROUND: Anticonvulsant properties have been attributed to extracts of the herbal medicine Valeriana officinalis. Our aims were to examine the anticonvulsant properties of valerenic acid and valerian extracts and to determine whether valerian preparations interact with the activity of other anti-epileptic drugs (phenytoin or clonazepam). To achieve these goals, we validated the adult zebrafish, Danio rerio, as an animal model for studying anticonvulsant drugs. METHODS: All drug treatments were administered by immersion in water containing the drug...
