Driving regulations for epilepsy in Europe. Seizure 2023; 109:83-91. [PMID: 37276778 DOI: 10.1016/j.seizure.2023.05.016] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/10/2023] [Revised: 05/12/2023] [Accepted: 05/20/2023] [Indexed: 06/07/2023] Open
Abstract
BACKGROUND Across Europe, there are differences regarding driving restrictions for patients with epilepsies and seizures. In the light of increasing mobility, knowledge about those different regulations is of high importance for counseling patients, and physicians. METHODS A structured online survey was sent to the official representatives of the different European ILAE chapters, asking for the local driving restrictions for patients with epilepsies, first seizures, syncopes, and psychogenic non-epileptic seizures. RESULTS The survey was sent to 38 chapters or representatives of 47 European Countries. 33 chapters answered. The majority of countries require 1 year of seizure-freedom for the ability to drive (Group 1, former categories A, B, B + E, F, G. H, K, L, and P; driving license which authorizes its holder to drive vehicle classes categories of the motor vehicle), usually with the need to continue antiseizure medication (ASM). Some countries have much stricter regulations before allowing for driving. Legal regulations after a first unprovoked seizure differ between 6 months for Group 1 license holders in most European countries, and one year in Luxembourg and Malta. In Serbia, there is no legal regulation for this special situation. The situation after a first seizure is even more complex for Group 2 license holders (former categories C1, C1+E, C, C + E, D1, D1+E, D, D + E). CONCLUSION Knowledge of the different recommendations of the individual European countries is of high relevance in the counseling of epilepsy patients. Europe-wide regulations, e.g. following the IBE-recommendations are needed to facilitate the patients' situation.

Management of epilepsy in older adults: A critical review by the ILAE Task Force on Epilepsy in the elderly. Epilepsia 2023; 64:567-585. [PMID: 36266921 DOI: 10.1111/epi.17426] [Citation(s) in RCA: 8] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2022] [Revised: 09/26/2022] [Accepted: 09/28/2022] [Indexed: 11/30/2022]
Abstract
Older adults represent a highly heterogeneous population, with multiple diverse subgroups. Therefore, an individualized approach to treatment is essential to meet the needs of each unique subgroup. Most comparative studies focusing on treatment of epilepsy in older adults have found that levetiracetam has the best chance of long-term seizure freedom. However, there is a lack of studies investigating other newer generation antiseizure medications (ASMs). Although a number of randomized clinical trials have been performed on older adults with epilepsy, the number of participants studied was generally small, and they only investigated short-term efficacy and tolerability. Quality of life as an outcome is often missing but is necessary to understand the effectiveness and possible side effects of treatment. Prognosis needs to move beyond the focus on seizure control to long-term patient-centered outcomes. Dosing studies with newer generation ASMs are needed to understand which treatments are the best in the older adults with different comorbidities. In particular, more high-level evidence is required for older adults with Alzheimer's disease with epilepsy and status epilepticus. Future treatment studies should use greater homogeneity in the inclusion criteria to allow for clearer findings that can be comparable with other studies to build the existing treatment evidence base.

German translation and validation of the brief Epilepsy Anxiety Survey Instrument (brEASI). Epilepsy Behav 2022; 134:108857.

Abstract
BACKGROUND Anxiety disorders remain undiagnosed in routine clinical practice in up to two thirds of affected patients with epilepsy despite their significant impact on medical and psychosocial outcomes. The study objective was to translate and validate the German 8-item "brief Epilepsy Anxiety Survey Instrument" (brEASI) to facilitate effective screening for the presence of anxiety disorders in German-speaking patients. METHODS After expert translation into German, the brEASI was completed by consecutive adult inpatients with epilepsy hospitalized for seizures at an academic reference epilepsy center. Patients also completed the Neurological Disorders Depression Inventory for Epilepsy (NDDI-E), the Generalized Anxiety Disorder scale (GAD-7) for external validity, and underwent a standardized interview (Mini-DIPS-OA) as a gold standard to determine the presence of an ICD-10 anxiety disorder (generalized anxiety disorder (GAD), panic disorder, agoraphobia, and social phobia). Receiver operating characteristics (ROC) were calculated to determine the diagnostic accuracy of the brEASI, including the associated area under the curve (AUC) statistics to determine the potential of the brEASI to identify ICD-10 anxiety disorders diagnosed by interview. For comparative purposes, these analyses were also conducted for the GAD-7. RESULTS Of 80 recruited adult inpatients with epilepsy, 18 (23 %) were found to have a current anxiety disorder through standardized interview. In this study, both brEASI and GAD-7 showed a better diagnostic performance at a cutoff of >5 than at the previously reported cutoff values of >6 and >9, respectively. The AUC of the German brEASI was outstanding (AUC = 0.90, 95 % confidence interval (CI) = 0.82-0.96) for detecting all anxiety disorders and excellent for detecting non-GAD disorders (AUC = 0.85, CI = 0.76-0.92) at a cutoff of >5. At this optimal cutoff of >5 the brEASI demonstrated better sensitivity and specificity (89 % and 84 %) for identifying anxiety disorders than the GAD-7 (83 % and 74 %). The final German version of the brEASI is free to download at https://www.v-neuro.de/veroeffentlichungen/. CONCLUSION The German version of the brEASI represents a valid and reliable epilepsy-specific anxiety screening instrument. A positive screening result should be followed by further diagnostic procedures. Appropriate therapeutic steps should be initiated if the presence of an anxiety disorder or other psychiatric disorders is confirmed.

Abstract
Aims This is an official interdisciplinary guideline published and coordinated by the German Society for Gynecology and Obstetrics (DGGG), the Austrian Society for Gynecology and Obstetrics (OEGGG) and the Swiss Society for Gynecology and Obstetrics (SGGG). The guideline was developed for use in German-speaking regions and is backed by numerous professional societies and organizations. The aim of this guideline is to provide an evidence- and consensus-based overview of the diagnostic approach and the management of hormonal contraception based on a systematic evaluation of the relevant literature. Methods To compile this S3-guideline, a systematic search for evidence was carried out in PubMed and the Cochrane Library to adapt existing guidelines and identify relevant reviews and meta-analyses. A structured evaluation of the evidence was subsequently carried out on behalf of the Guidelines Commission of the DGGG, and a structured consensus was achieved based on consensus conferences attended by representative members from the different specialist societies and professions. Recommendations Evidence-based recommendations about the advice given to women requesting contraception were compiled. The guideline particularly focuses on prescribing contraceptives which are appropriate to women's individual needs, take account of her personal circumstances, and have few or no side effects.

Epilepsy as a key feature in two works of fantastic literature by Alfred Kubin and Hermann Weyl: With a brief review of epilepsy in fantastic literature. Epilepsy Behav 2020; 111:107191.

Abstract
Among the many literary works of all styles and types referring to epilepsy, fantastic literature forms a distinct and interesting subgroup. The article draws attention to two such works belonging to early 20th century German avant-garde where epilepsy is a key feature. Of the authors, Austrian Alfred Kubin (1877-1959) was a renowned artist and illustrator whose only published (and illustrated) novel "The Other Side" (1909) can be understood as the narrative of a complex epileptic experience, perhaps a dreamy state. Of the other author, Hermann Weyl (1893-1960), very little is known. He was a Jewish neuropsychiatrist who emigrated from Nazist Germany to Argentina in 1933. His only published literary work, the novella "The Epileptic" (1927), displays high literary ambitions. The topic epilepsy provided for him the desired access to the fantastic realm, and his professionality enabled him to address with great expertise aspects as diverse as postictal psychosis and social stigmatization. Both works are, thus, valuable contributions to the tradition of epilepsy in fantastic literature. A brief review of the latter includes Edgar Allan Poe, Victor Hugo, Charles Dickens, Gustav Meyrink, Mervin Peake, Russell Hoban, Eraldo Baldini, Haruki Murakami, Adam Fawer, and Christoph Ransmayr.

EEG in fitness to drive evaluations in people with epilepsy - Considerable variations across Europe. Seizure 2020; 79:56-60. [PMID: 32416569 DOI: 10.1016/j.seizure.2020.04.013] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2020] [Revised: 04/24/2020] [Accepted: 04/26/2020] [Indexed: 11/25/2022] Open
Abstract
PURPOSE Epilepsy patients consider driving issues to be one of their most serious concerns. Ideally, decisions regarding fitness to drive should be based upon thorough evaluations by specialists in epilepsy care. In 2009, an EU directive was published aiming to harmonize evaluation practices within European countries, but, despite these recommendations, whether all epileptologists use the same criteria is unclear. We therefore conducted this study to investigate routine practices on how epileptologists at European epilepsy centers evaluate fitness to drive. METHODS A questionnaire was sent to 63 contact persons identified through the European Epi-Care and the E-pilepsy network. The questionnaire addressed how fitness-to-drive evaluations were conducted, the involvement of different professionals, the use and interpretation of EEG, and opinions on existing regulations and guidelines. RESULTS The questionnaire was completed by 35 participants (56 % response rate). Results showed considerable variation regarding test routines and the emphasis placed on the occurrence and extent of epileptiform discharges revealed by EEG. 82 % of the responders agreed that there was a need for more research on how to better evaluate fitness-to-drive in people with epilepsy, and 89 % agreed that regulations on fitness to drive evaluations should be internationally coordinated. CONCLUSION Our survey showed considerable variations among European epileptologists regarding use of EEG and how findings of EEG pathology should be assessed in fitness-to-drive evaluations. There is a clear need for more research on this issue and international guidelines on how such evaluations should be carried out would be of value.

Could the 2017 ILAE and the four-dimensional epilepsy classifications be merged to a new "Integrated Epilepsy Classification"? Seizure 2020; 78:31-37. [PMID: 32155575 DOI: 10.1016/j.seizure.2020.02.018] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2020] [Accepted: 02/29/2020] [Indexed: 11/30/2022] Open
Abstract
Over the last few decades the ILAE classifications for seizures and epilepsies (ILAE-EC) have been updated repeatedly to reflect the substantial progress that has been made in diagnosis and understanding of the etiology of epilepsies and seizures and to correct some of the shortcomings of the terminology used by the original taxonomy from the 1980s. However, these proposals have not been universally accepted or used in routine clinical practice. During the same period, a separate classification known as the "Four-dimensional epilepsy classification" (4D-EC) was developed which includes a seizure classification based exclusively on ictal symptomatology, which has been tested and adapted over the years. The extensive arguments for and against these two classification systems made in the past have mainly focused on the shortcomings of each system, presuming that they are incompatible. As a further more detailed discussion of the differences seemed relatively unproductive, we here review and assess the concordance between these two approaches that has evolved over time, to consider whether a classification incorporating the best aspects of the two approaches is feasible. To facilitate further discussion in this direction we outline a concrete proposal showing how such a compromise could be accomplished, the "Integrated Epilepsy Classification". This consists of five categories derived to different degrees from both of the classification systems: 1) a "Headline" summarizing localization and etiology for the less specialized users, 2) "Seizure type(s)", 3) "Epilepsy type" (focal, generalized or unknown allowing to add the epilepsy syndrome if available), 4) "Etiology", and 5) "Comorbidities & patient preferences".

Abstract
The influence of a single layer graphene on the interface between a polished steel surface and the model lubricant hexadecane is explored by high-resolution force microscopy. Nanometer-scale friction is reduced by a factor of three on graphene compared to the steel substrate, with an ordered layer of hexadecane adsorbed on the graphene. Graphene furthermore induces a molecular ordering in the confined lubricant with an average range of 4-5 layers and with a strongly increased load-bearing capacity compared to the lubricant on the bare steel substrate.

Abstract
Background Low anterior resection syndrome (LARS) is a frequent problem after rectal resection. Transanal irrigation (TAI) has been suggested as an effective treatment in patients who have developed LARS. This prospective RCT was undertaken to evaluate the effect of TAI as a prophylactic treatment to prevent symptoms of LARS. Methods Patients who had undergone ultralow rectal resection were randomized to start TAI on a daily basis, or to serve as a control with supportive therapy only after ileostomy closure. All patients were seen after 1 week, 1 month and 3 months, and the maximum number of defaecation episodes per day and night documented during follow‐up. Wexner score, LARS score and Short Form 36 questionnaire responses were evaluated in both groups. Results Thirty‐seven patients could be evaluated according to protocol (TAI 18, control 19). The maximum number of stool episodes per day and per night was significantly lower among patients who underwent TAI at 1 month (median 3 versus 7 episodes/day in TAI versus control group, P = 0·003; 0 versus 3 episodes/night, P = 0·001) and 3 months (3 versus 5 episodes per day, P = 0·006; 0 versus 1 episodes/night, P = 0·002). LARS scores were significantly better in the TAI group after 1 month (median 16 versus 32 in control group; P = 0·044) and 3 months (9 versus 31; P = 0·001). A significantly better result in terms of Wexner score was seen in the TAI group after 3 months (median 2 versus 6 in controls; P = 0·046). Conclusion Prophylactic TAI led to a significantly better functional outcome compared with supportive therapy for up to 3 months. Registration number: DRKS00011752 (

Noncompliance of patients with driving restrictions due to uncontrolled epilepsy. Epilepsy Behav 2019; 91:86-89.

Abstract
Epilepsies are a common and chronic neurological disorder characterized by sustained risk of recurrent seizures. Because of paroxysmal and often unpredictable occurrence of seizures, patients with uncontrolled epilepsy are subject to disease-specific restrictions in daily life, such as their career choice or specific work limitations. According to German law and many other European and international guidelines, driving is strictly prohibited in patients with uncontrolled epilepsy so as to increase active and passive safety in public road traffic. Nevertheless, a significant percentage of patients probably do not comply with these legal restrictions and drive on a regular basis. For this study, we analyzed a representative German cohort with 302 patients (mean age: 45.0 years ± 16.4; 48% male) with established epilepsy to identify the number of patients driving without permission. Overall, 58.6% (n = 177) of patients had a driving license, 71.1% (n = 69/97) of patients were in seizure remission, and 52.7% (n = 108/205) of patients had uncontrolled epilepsy. Among patients in seizure remission, 54.6% (n = 53/97) reported regular driving while, among patients with uncontrolled epilepsy, 15.1% (n = 31/205) reported driving on a regular basis. No patient in the cohort stated driving without a valid license. Permanent employment, freelance work, the absence of a relevant disability, and living alone were identified as significant risk factors, which underlines the already existing evidence for the importance of a possible restricted access to the labor market as motive for disregarding legal driving restrictions. In our opinion, specialized and generally available social counseling with a special focus on vocational and career guidance is urgently needed to improve compliance with epilepsy-caused driving restrictions and the underlying reasons for violating these rules. In addition, more effort has to be spent on improving diagnostics and treatment of epilepsy to reduce the number of patients with uncontrolled seizures. Comprehensive introduction of self-driving vehicles may also help to improve mobility of patients with refractory epilepsy.

Abstract
Zusammenfassung
Hintergrund Das Manuskript ist eine aktualisierte und stark erweiterte Version der 2012 entstandenen DGN-Leitlinie zum ersten epileptischen Anfall und Epilepsien im Erwachsenenalter. Ziel der Leitlinie ist es, den gegenwärtigen Stand des Wissens zur Diagnostik und Therapie anhand der zur Verfügung stehenden wissenschaftlichen Literatur zusammenzufassen und damit zur Verbesserung der diagnostischen und therapeutischen Abläufe und deren Vereinheitlichung beizutragen.Die Leitlinie behandelt ausschließlich Epilepsien im Erwachsenenalter, Epilepsien bei Kindern werden nicht berücksichtigt. Ebenso werden der Status epilepticus sowie Anfälle infolge von immunvermittelten Erkrankungen des Gehirns nicht behandelt, da hierzu eigene Leitlinien vorliegen.
Methodik Das Leitliniengremium wurde durch Experten der Neurologie gebildet, die eine besondere Expertise auf dem Gebiet der Epilepsie besitzen und sowohl aus dem klinischen als auch aus dem niedergelassenen Bereich kommen. Neben der Deutschen Gesellschaft für Neurologie (DGN) sind auch die Deutsche Gesellschaft für Neurochirurgie e. V. (DGNC), die Österreichische Sektion der Internationalen Liga gegen Epilepsie, die Schweizerische Liga gegen Epilepsie sowie die Luxemburgische Gesellschaft für Neurologie beteiligt. Es wurde darauf geachtet, auch Mitglieder der jüngeren Generation in das Redaktionskomitee aufzunehmen. Die seit der letzten Ausgabe der Leitlinie 2012 neu erschienene Literatur wurde gesichtet und in die aktuelle Fassung eingearbeitet. Die Methodik der Leitlinienentwicklung entsprach einem nominalen Gruppenprozess und einem modifizierten Delphi-Verfahren (Vorlage zuvor produzierter Texte oder Tabellen, mehrstufige schriftliche Befragungsmethode, Rückkopplungsprozess, Information der Teilnehmer über die Gruppenantwort, Diskussion aller Kommentare mit ggf. daraus resultierender Überarbeitung des Entwurfes, Gruppenmitglieder haben die Möglichkeit einer Überprüfung bzw. eines Vergleichs ihrer Aussagen). Der Konsensprozess entsprach den Regeln der AWMF und der DGN zum Umgang mit potenziellen Interessenkonflikten.
Ergebnis Wichtigste Neuerung ist eine erneuerte Definition der Epilepsie, ein wesentlich neuer Aspekt dieser Definition ist die Frage, ob eine Epilepsie „überwunden“ werden kann. Auch zur Klassifikation von Anfällen und Epilepsien ist eine neue Version erschienen, die im Wesentlichen wieder der Version von 1989 entspricht. Als wichtigste therapeutische Neuerung hat sich seit der letzten Fassung der Leitlinie von 2012 das Spektrum der Antiepileptika deutlich erweitert, neue Medikamente sind zugelassen worden (Perampanel, Brivaracetam) oder haben ihre Zulassung erweitert (Zonisamid, Lacosamid, Eslicarbazepinacetat). Der Einsatz von Valproinsäure bei Frauen und Mädchen wird zunehmend kritisch gesehen, in der Leitlinie wird ausführlich auf diese Problematik und die Behandlung von Frauen mit Epilepsie eingegangen. Neben der medikamentösen Therapie werden operative Therapien und Stimulationsverfahren behandelt.Psychosoziale Aspekte sowie die Bereiche Fahrtauglichkeit, Ausbildung und Beruf sowie die Problematik des Absetzens von Medikamenten bei langjähriger Anfallsfreiheit werden umfangreicher als bisher diskutiert, auch wurden Abschnitte zur Mortalität, zu Erste-Hilfe-Maßnahmen und zu akuten symptomatischen Anfällen (ASA) neu in die Leitlinie aufgenommen. Ein eigenes Kapitel zur Pharmakokinetik befasst sich mit dem Interaktionspotenzial von Antiepileptika mit anderen Medikamenten sowie dem möglichen Einfluss auf Vitamin- und Hormonspiegel. Insbesondere Therapien maligner Erkrankungen können durch Interaktionen kritisch beeinflusst werden.

Abstract
OBJECTIVE To examine the attitudes toward counseling about sudden unexpected death in epilepsy (SUDEP) and other epilepsy risk factors among Austrian, German, and Swiss neurologists and neuropediatricians, and to determine factors associated with not discussing SUDEP. METHODS Questionnaires were sent to approximately 5,000 neurologists and neuropediatricians in 2014 regarding respondents' demographics, their working environments, and how often they discussed SUDEP, suicidal ideations on anticonvulsive medication, driving restrictions, and risks in daily life activities. RESULTS In total, 519 surveys were completed (respondents' mean age: 45.5 years, 41.6% female, 66.9% adult neurologists, 31.0% neuropediatricians). A minority of 2.7% reported that they counseled all of their patients on SUDEP, 8.7% counseled most of the time (50-90%), 20.8% sometimes (10-49%), 44.5% rarely (1-9%), and 23.3% reported not counseling about SUDEP at all. In contrast, 92.9% reported that they counseled all patients about driving restrictions and 81.5% about risks in daily life activities. Suicidal ideations were discussed in 59.0% for some and in 3.3% for all patients, whereas 35.1% of respondents reported never discussing suicidal ideations. Independent predictors of not discussing SUDEP were no additional epilepsy training, no or uncertain SUDEP cases in the past, <10 years in practice, <25 epilepsy patients seen per quarter, and the opinion of a lack of consequences in SUDEP prevention. The opinion that SUDEP is a risk factor in particular patient groups and the attitude that all risks should be discussed predicted counseling on SUDEP. SIGNIFICANCE Our findings show a discrepancy between guidelines and practice regarding the discussion of premature mortality due to SUDEP or suicidality. Both are not discussed at all by a substantial proportion of neurologists and neuropediatricians. This is in contrast to ubiquitous education about driving restrictions. Dissemination of knowledge among physicians about potential preventive strategies might increase the likelihood of discussion. Clinical practice guidelines are welcomed by the majority of physicians in this process.

De novo loss- or gain-of-function mutations in KCNA2 cause epileptic encephalopathy. Nat Genet 2015; 47:393-399.

Abstract
Epileptic encephalopathies are a phenotypically and genetically heterogeneous group of severe epilepsies accompanied by intellectual disability and other neurodevelopmental features. Using next-generation sequencing, we identified four different de novo mutations in KCNA2, encoding the potassium channel KV1.2, in six isolated patients with epileptic encephalopathy (one mutation recurred three times independently). Four individuals presented with febrile and multiple afebrile, often focal seizure types, multifocal epileptiform discharges strongly activated by sleep, mild to moderate intellectual disability, delayed speech development and sometimes ataxia. Functional studies of the two mutations associated with this phenotype showed almost complete loss of function with a dominant-negative effect. Two further individuals presented with a different and more severe epileptic encephalopathy phenotype. They carried mutations inducing a drastic gain-of-function effect leading to permanently open channels. These results establish KCNA2 as a new gene involved in human neurodevelopmental disorders through two different mechanisms, predicting either hyperexcitability or electrical silencing of KV1.2-expressing neurons.

Abstract
OBJECTIVES Cognitive comorbidity at epilepsy onset reflects disease severity and provides a baseline estimate of reserve capacities with regard to the effects of epilepsy and its treatment. Given the high incidence of epilepsy at an older age, this study analyzed objective and subjective cognition as well as quality of life in elderly patients with new-onset focal epilepsy before initiation of anti-epileptic treatment. MATERIALS AND METHODS A total of 257 untreated patients (60-95 years of age) with new-onset epilepsy underwent objective assessment of executive function (EpiTrack) and performed subjective ratings of cognition (Portland Neurotoxicity Scale) and quality of life (QoL; QOLIE-31). RESULTS According to age-corrected norms, 58% of patients (N=257) demonstrated deficits in executive function; major determinants were cerebrovascular etiology, neurological comorbidity, and higher body mass index. Subjective ratings indicated deficits in up to 27% of patients. Self-perceived deficits were associated with neurological, cardiovascular, and/or psychiatric comorbidity, whereas poorer QoL was related to neurological comorbidity and female gender. Objectively assessed executive functions correlated with subjective social functioning, energy, motor function, and vigilance. CONCLUSIONS We found a relatively high QoL, a low rate of subjective impairment, but a high incidence of objective executive deficits in untreated elderly patients with new-onset epilepsy. Neurological status and body mass index, rather than seizure frequency or severity, were risk factors for cognitive impairment. Given the relevance of cognition in the course of epilepsy and its treatment, routine screening before treatment initiation is highly recommended.

Epilepsy, hippocampal sclerosis and febrile seizures linked by common genetic variation around SCN1A. Brain 2013; 136:3140-50.

Abstract
Epilepsy comprises several syndromes, amongst the most common being mesial temporal lobe epilepsy with hippocampal sclerosis. Seizures in mesial temporal lobe epilepsy with hippocampal sclerosis are typically drug-resistant, and mesial temporal lobe epilepsy with hippocampal sclerosis is frequently associated with important co-morbidities, mandating the search for better understanding and treatment. The cause of mesial temporal lobe epilepsy with hippocampal sclerosis is unknown, but there is an association with childhood febrile seizures. Several rarer epilepsies featuring febrile seizures are caused by mutations in SCN1A, which encodes a brain-expressed sodium channel subunit targeted by many anti-epileptic drugs. We undertook a genome-wide association study in 1018 people with mesial temporal lobe epilepsy with hippocampal sclerosis and 7552 control subjects, with validation in an independent sample set comprising 959 people with mesial temporal lobe epilepsy with hippocampal sclerosis and 3591 control subjects. To dissect out variants related to a history of febrile seizures, we tested cases with mesial temporal lobe epilepsy with hippocampal sclerosis with (overall n = 757) and without (overall n = 803) a history of febrile seizures. Meta-analysis revealed a genome-wide significant association for mesial temporal lobe epilepsy with hippocampal sclerosis with febrile seizures at the sodium channel gene cluster on chromosome 2q24.3 [rs7587026, within an intron of the SCN1A gene, P = 3.36 × 10(-9), odds ratio (A) = 1.42, 95% confidence interval: 1.26-1.59]. In a cohort of 172 individuals with febrile seizures, who did not develop epilepsy during prospective follow-up to age 13 years, and 6456 controls, no association was found for rs7587026 and febrile seizures. These findings suggest SCN1A involvement in a common epilepsy syndrome, give new direction to biological understanding of mesial temporal lobe epilepsy with hippocampal sclerosis with febrile seizures, and open avenues for investigation of prognostic factors and possible prevention of epilepsy in some children with febrile seizures.

Abstract
Epilepsy is both a disease of the brain and the mind. Brain diseases, structural and/or functional, underlie the appearance of epilepsy, but the notion of epilepsy is larger and cannot be reduced exclusively to the brain. We can therefore look at epilepsy from two angles. The first perspective is intrinsic: the etiology and pathophysiology, problems of therapy, impact on the brain networks, and the "mind" aspects of brain functions - cognitive, emotional, and affective. The second perspective is extrinsic: the social interactions of the person with epilepsy, the influence of the surrounding environment, and the influences of epilepsy on society. All these aspects reaching far beyond the pure biological nature of epilepsy have been the topics of two International Congresses of Epilepsy, Brain, and Mind that were held in Prague, Czech Republic, in 2010 and 2012 (the third Congress will be held in Brno, Czech Republic on April 3-5, 2014; www.epilepsy-brain-mind2014.eu). Here, we present the first of two papers with extended summaries of selected presentations of the 2012 Congress that focused on epilepsy, behavior, and art.

Abstract
Placebo effects in the therapy of epilepsy were already known before the introduction of effective antiepileptic drugs (AEDs). They have physiologic correlates, and are even stronger in other neurologic disorders such as pain. Placebo effects in epilepsy have many facets. Our understanding of this phenomenon has increased in the last two decades: placebo effects are stronger in children than in adults, and may be culture- and setting-dependent; and impressive placebo effects occur in animals with epilepsy as well. More research is needed to fully elucidate the mechanism of placebo effects in epilepsy care, particularly as we go forth with studies addressing the issue of pharmacoresistance.

Abstract
PURPOSE Epilepsies have a highly heterogeneous background with a strong genetic contribution. The variety of unspecific and overlapping syndromic and nonsyndromic phenotypes often hampers a clear clinical diagnosis and prevents straightforward genetic testing. Knowing the genetic basis of a patient's epilepsy can be valuable not only for diagnosis but also for guiding treatment and estimating recurrence risks. METHODS To overcome these diagnostic restrictions, we composed a panel of genes for Next Generation Sequencing containing the most relevant epilepsy genes and covering the most relevant epilepsy phenotypes known so far. With this method, 265 genes were analyzed per patient in a single step. We evaluated this panel on a pilot cohort of 33 index patients with concise epilepsy phenotypes or with a severe but unspecific seizure disorder covering both sporadic and familial cases. KEY FINDINGS We identified presumed disease-causing mutations in 16 of 33 patients comprising sequence alterations in frequently as well as in less commonly affected genes. The detected aberrations encompassed known and unknown point mutations (SCN1A p.R222X, p. E289V, p.379R, p.R393H; SCN2A p.V208E; STXBP1 p.R122X; KCNJ10 p.L68P, p.I129V; KCTD7 p.L108M; KCNQ3 p.P574S; ARHGEF9 p.R290H; SMS p.F58L; TPP1 p.Q278R, p.Q422H; MFSD8 p.T294K), a putative splice site mutation (SCN1A c.693A> p.T/P231P) and small deletions (SCN1A p.F1330Lfs3X [1 bp]; MFSD8 p.A138Dfs10X [7 bp]). All mutations have been confirmed by conventional Sanger sequencing and, where possible, validated by parental testing and segregation analysis. In three patients with either Dravet syndrome or myoclonic epilepsy, we detected SCN1A mutations (p.R222X, p.P231P, p.R393H), even though other laboratories had previously excluded aberrations of this gene by Sanger sequencing or high-resolution melting analysis. SIGNIFICANCE We have developed a fast and cost-efficient diagnostic screening method to analyze the genetic basis of epilepsies. We were able to detect mutations in patients with clear and with unspecific epilepsy phenotypes, to uncover the genetic basis of many so far unresolved cases with epilepsy including mutation detection in cases in which previous conventional methods yielded falsely negative results. Our approach thus proved to be a powerful diagnostic tool that may contribute to collecting information on both common and unknown epileptic disorders and in delineating associated phenotypes of less frequently mutated genes.

Abstract
Modern medical treatment of epilepsy renders two out of three newly diagnosed epilepsy patients seizure-free. More than 20 drugs are currently available and even for epilepsy specialists it may not be easy to select the drug which is best suited for the individual patient. Current guidelines recommend drugs with proven efficacy and optimal tolerability that address the individual needs of the patient. Non-enzyme-inducing agents are preferred if possible, to protect the patient from loss of efficacy when taking other medications for life-threatening disorders. In one out of three patients, seizure freedom is currently not possible due to drug-resistance, which requires a prompt diagnostic and therapeutic reevaluation of the epilepsy.

Abstract
Purpose Several recent reports of genomic microdeletions in epilepsy will generate further research; discovery of more microdeletions and other important classes of variants may follow. Detection of such genetic abnormalities in patients being evaluated for surgical treatment might raise concern that a genetic defect, possibly widely expressed in the brain, will affect surgical outcome. Methods A reevaluation was undertaken of clinical presurgical data, histopathology of surgical specimen, and postsurgical outcome in patients with mesial temporal lobe epilepsy (MTLE) who have had surgical treatment for their drug-resistant seizures, and who have been found to have particular genomic microdeletions. Key Findings Three thousand eight hundred twelve patients with epilepsy were genotyped and had a genome-wide screen to identify copy number variation. Ten patients with MTLE, who had resective epilepsy surgery, were found to have 16p13.11 microdeletions or other microdeletions >1 Mb. On histopathology, eight had classical hippocampal sclerosis (HS), one had nonspecific findings, and one had a hamartoma. Median postsurgical follow-up time was 48 months (range 10–156 months). All patients with HS were seizure-free after surgery, International League Against Epilepsy (ILAE) outcome class 1, at last follow-up; the patient with nonspecific pathology had recurrence of infrequent seizures after 7 years of seizure freedom. The patient with a hamartoma never became seizure-free. Significance Large microdeletions can be found in patients with “typical” MTLE. In this small series, patients with MTLE who meet criteria for resective surgery and harbor large microdeletions, at least those we have detected, can have a good postsurgical outcome. Our findings add to the spectrum of causal heterogeneity of MTLE + HS.

Abstract
PURPOSE Primary brain tumors and metastases are common causes of symptomatic epilepsy. Seizures, neurological and neuropsychological deficits can interfere with driving ability. The present paper aims to systematically review the incidence of epileptic seizures in brain tumor patients and to discuss driving ability in the context of the current German guidelines and expert opinions. METHODS To evaluate the incidence of epileptic seizures which occur at the beginning and in the course of the disease, we performed a systematic literature research in PubMed from 1960 to 2007. Additionally on the basis of this data we performed a survey collecting expert opinions regarding the driving ability of brain tumor patients from members of the German working groups "Arbeitsgemeinschaft für prächirurgische Epilepsiediagnostik und operative Epilepsietherapie" (Working Group for Presurgical Epilepsy Diagnostics and Operative Epileptic Therapy) and "Neuroonkologische Arbeitsgemeinschaft" (Neuro-oncological Working Group). RESULTS The incidence of epileptic seizures depends on the entity, dignity and localization of the tumor. The driving ability of brain tumor patients is not explicitly regulated in Germany. Of the interviewed experts 72% judged the guidelines to be precise enough and 44% did not want to deprive the patients of their driving ability without a first seizure, independent of the individual risk. DISCUSSION The available studies are methodologically insufficient and show that a further evaluation is necessary to assess the driving ability. Possible restrictions of the driving ability in patients with a high risk of seizures in the course of the disease have to take into account the balance between individual rights and the interests of the general public.

Abstract
PURPOSE Ictal asystole (IA) and ictal bradycardia (IB) are rare autonomic symptoms during epileptic seizures and may be potentially life-threatening. Guidelines for the care of these patients are missing. The aim of this multicenter study was to evaluate the management and long-term outcome in patients with IA and IB. PATIENTS AND METHODS All patients with IA and IB were included from four epilepsy centers (Bielefeld, Kork, Marburg, and Zürich) from 2002 until 2009. Using a standardized assessment form, clinical data, treatment decisions, and outcomes were extracted from patient charts and simultaneous electroencephalography/electrocardiography (EEG/ECG) recordings. KEY FINDINGS Seizures with IA or IB were identified in 16 patients. In all patients an associated temporal seizure pattern was recorded and in 15 patients, sudden falls, fainting, or trauma was previously reported or recorded during the monitoring. In three patients (18.8%) diagnosis of focal epilepsy was newly established and anticonvulsive treatment was initiated. Two patients with refractory epilepsy underwent epilepsy surgery. In seven patients (43.8%) a cardiac pacemaker was implanted. In 14 of 16 treated patients, seizure freedom (n = 5) or absence of sudden falls, fainting, or trauma (n = 9) could be achieved. Two patients denied epilepsy surgery as well as a pacemaker and continue to have frequent falls and trauma. SIGNIFICANCE Our study demonstrates that epilepsy surgery and antiepileptic drugs may lead to sustained freedom of seizures as well as ictal syncope. In drug-resistant patients not suitable for epilepsy surgery, implantation of a cardiac pacemaker may prevent sudden falls as well as trauma. Based on our results and previously reported cases we propose a treatment algorithm.

Abstract
OBJECTIVE The goal of this study was to investigate whether dysplastic amygdalae show an impaired response as revealed by functional MRI (fMRI). METHODS A fearful face fMRI paradigm using video sequences, as we have recently applied, was used in 25 patients with temporal lobe epilepsy (TLE): 24 had mesial TLE (14 right-, nine left-sided, one bilateral); one left lateral neocortical TLE. T1-, T2-weighted and fluid attenuated inversion recovery (FLAIR) MRI sequences were assessed for the detection and categorisation of structural amygdalar abnormalities according to size and MR signal intensity. Of the 25 patients, five patients had probable dysplastic amygdala (pDA): two right- and three left-sided. RESULTS A fearful face paradigm led to significant amygdalar activation in all but one patient (p<0.05). In 15 (60%) of the patients amygdalar activation was found contralateral and in four (16%) ipsilateral to the side of seizure onset. Bilateral amygdalar activation was registered in five (20%) patients. In two patients with right-sided and one with left-sided pDA, fMRI activation was observed only in the contralateral amygdala. In two out of three patients with left-sided pDA we found significant ipsilateral amygdalar fMRI-responses. CONCLUSION Unilateral pDA does not necessarily affect the amygdalar fMRI BOLD-response.

Abstract
Partial epilepsies have a substantial heritability. However, the actual genetic causes are largely unknown. In contrast to many other common diseases for which genetic association-studies have successfully revealed common variants associated with disease risk, the role of common variation in partial epilepsies has not yet been explored in a well-powered study. We undertook a genome-wide association-study to identify common variants which influence risk for epilepsy shared amongst partial epilepsy syndromes, in 3445 patients and 6935 controls of European ancestry. We did not identify any genome-wide significant association. A few single nucleotide polymorphisms may warrant further investigation. We exclude common genetic variants with effect sizes above a modest 1.3 odds ratio for a single variant as contributors to genetic susceptibility shared across the partial epilepsies. We show that, at best, common genetic variation can only have a modest role in predisposition to the partial epilepsies when considered across syndromes in Europeans. The genetic architecture of the partial epilepsies is likely to be very complex, reflecting genotypic and phenotypic heterogeneity. Larger meta-analyses are required to identify variants of smaller effect sizes (odds ratio <1.3) or syndrome-specific variants. Further, our results suggest research efforts should also be directed towards identifying the multiple rare variants likely to account for at least part of the heritability of the partial epilepsies. Data emerging from genome-wide association-studies will be valuable during the next serious challenge of interpreting all the genetic variation emerging from whole-genome sequencing studies.

Rare deletions at 16p13.11 predispose to a diverse spectrum of sporadic epilepsy syndromes. Am J Hum Genet 2010; 86:707-18.

Abstract
Deletions at 16p13.11 are associated with schizophrenia, mental retardation, and most recently idiopathic generalized epilepsy. To evaluate the role of 16p13.11 deletions, as well as other structural variation, in epilepsy disorders, we used genome-wide screens to identify copy number variation in 3812 patients with a diverse spectrum of epilepsy syndromes and in 1299 neurologically-normal controls. Large deletions (> 100 kb) at 16p13.11 were observed in 23 patients, whereas no control had a deletion greater than 16 kb. Patients, even those with identically sized 16p13.11 deletions, presented with highly variable epilepsy phenotypes. For a subset of patients with a 16p13.11 deletion, we show a consistent reduction of expression for included genes, suggesting that haploinsufficiency might contribute to pathogenicity. We also investigated another possible mechanism of pathogenicity by using hybridization-based capture and next-generation sequencing of the homologous chromosome for ten 16p13.11-deletion patients to look for unmasked recessive mutations. Follow-up genotyping of suggestive polymorphisms failed to identify any convincing recessive-acting mutations in the homologous interval corresponding to the deletion. The observation that two of the 16p13.11 deletions were larger than 2 Mb in size led us to screen for other large deletions. We found 12 additional genomic regions harboring deletions > 2 Mb in epilepsy patients, and none in controls. Additional evaluation is needed to characterize the role of these exceedingly large, non-locus-specific deletions in epilepsy. Collectively, these data implicate 16p13.11 and possibly other large deletions as risk factors for a wide range of epilepsy disorders, and they appear to point toward haploinsufficiency as a contributor to the pathogenicity of deletions.
