    ABSTRACT: UK guidelines do not recommend prescribing emergency antiepileptic drugs after first simple febrile seizures or for single afebrile seizures. Non-adherence to the guidelines could result in substantial health service cost. Scottish national hospital discharge records were used to identify children aged one month to 4 years admitted for a first febrile seizures or single afebrile seizures between April 2009 and March 2012. Prescriptions for antiepileptic drugs within 12 months of index admission were identified on the national community prescribing database by matching unique patient identifiers. There were 1,978 and 663 children admitted for febrile seizures and single afebrile seizures, respectively. One percent of children admitted with febrile seizures and 1.7% with single afebrile seizures had a subsequent community prescription record for emergency antiepileptic drugs within 12 months of index admission. Total cost of emergency antiepileptic drugs following febrile seizures and single afebrile seizures for the study period was just over £900. Health care providers and policy makers can be reassured that emergency antiepileptic drugs are not being inappropriately overprescribed for febrile seizures and single afebrile seizures.

    ABSTRACT: A healthy 29-year-old man suffered from adult-onset epilepsy, characterized by polymorphic progressive seizures resistant to AEDs, leading to unilateral cortical deficits and atrophy of the left hemisphere. The disorder satisfied the clinical, EEG, and imaging criteria for a diagnosis of Rasmussen's encephalitis. During the acute phase of the disease, intrathecal synthesis of specific anti-CMV IgG was identified. This case was characterized by a very mild course and remission of seizures following a treatment with high-dose intravenous polyvalent immunoglobulins containing a high anti-CMV titre. The patient remained symptomless for more than 15 years from clinical onset and more than eight years after the discontinuation of immunological therapy. In agreement with a recent report, this case confirms that adult-onset Rasmussen's encephalitis syndrome may occur with a very mild clinical picture and persistent remission. In this case, the specific index for intrathecal production of anti-CMV antibodies suggested possible CMV involvement, indicating specific immuno-therapy as a treatment choice.

    ABSTRACT: Epilepsy surgery is beneficial to patients suffering from drug-resistant temporal lobe epilepsy in the short term, but fewer reports of long-term outcomes have been published. To clarify the long-term outcomes of seizure control and health-related quality of life after epilepsy surgery, we enrolled 48 patients suffering from drug-resistant temporal lobe epilepsy. All of the patients received comprehensive presurgical evaluations, including the Quality of Life in Epilepsy Inventory-89 (QOLIE-89) questionnaire to measure their health-related quality of life. Among the patients, 28 patients received surgery (surgical group) and 20 patients remained under medication (medical group). Eight years later, the seizure frequency and QOLIE-89 were evaluated. The seizure-free rate was much higher in the surgical group (53.6%) than in the medical group (5%), eight years after the initial evaluation. The follow-up QOLIE-89 score was significantly higher in the surgical group than in the medical group. Moreover, the seizure frequency inversely correlated to the QOLIE-89 score, regardless of the treatment group. Our results provide evidence that epilepsy surgery confers benefits with respect to seizure control and health-related quality of life for drug-resistant temporal lobe epilepsy patients based on long-term follow-up.

    ABSTRACT: The challenges to individuals with epilepsy extend far beyond the seizures. Co-morbidities in epilepsy are very common and are often more problematic to individuals than the seizures themselves. In this review, the pathophysiological mechanisms of cognitive impairment are discussed. While aetiology of the epilepsy has a significant influence on cognition, there is increasing evidence that prolonged or recurrent seizures can cause or exacerbate cognitive impairment. Alterations in signalling pathways and neuronal network function play a major role in both the pathophysiology of epilepsy and the epilepsy comorbidities. However, the biological underpinnings of cognitive impairment can be distinct from the pathophysiological processes that cause seizures.

    ABSTRACT: We present three patients with epilepsy of infancy with migrating focal seizures treated with the ketogenic diet. Between February 1, 2012 and January 31, 2014, three patients who met the diagnostic criteria for migrating focal seizures in infancy at our department were placed on the ketogenic diet and followed for a minimum of seven months. Two of the three children responded well to the ketogenic diet. One of these patients became seizure-free and his neuropsychological performance also significantly improved. The other child had a seizure reduction of 75% to 99% with only weekly seizures and moderate psychomotor improvement. For these two patients who responded well to the ketogenic diet, hospital admission was not required. The remaining patient had a seizure reduction of less than 50%. Tolerability of the diet was good in all three patients. Early treatment with the ketogenic diet should be considered for epilepsy of infancy with migrating focal seizures to control seizures and status epilepticus, and avoid progressive cognitive impairment.

    ABSTRACT: Auditory auras are typically considered to localize to the temporal neocortex. Herein, we present two cases of frontal operculum/perisylvian epilepsy with auditory auras. Following a non-invasive evaluation, including ictal SPECT and magnetoencephalography, implicating the frontal operculum, these cases were evaluated with invasive monitoring, using stereoelectroencephalography and subdural (plus depth) electrodes, respectively. Spontaneous and electrically-induced seizures showed an ictal onset involving the frontal operculum in both cases. A typical auditory aura was triggered by stimulation of the frontal operculum in one. Resection of the frontal operculum and subjacent insula rendered one case seizure- (and aura-) free. From a holodological (network) perspective, we discuss these findings with consideration of the perisylvian and insular network(s) interconnecting the frontal and temporal lobes, and revisit the non-invasive data, specifically that of ictal SPECT.

    ABSTRACT: To present a retrospective study of nine children with Panayiotopoulos syndrome associated with diffuse spikes and waves as the sole EEG manifestation at onset. Charts of children with typical clinical criteria of Panayiotopoulos syndrome, electroclinically followed between February 2000 and February 2012, were reviewed. Among 150 patients who met the electroclinical criteria of Panayiotopoulos syndrome, we identified nine children who presented with the typical clinical manifestations but who, on EEG, only had diffuse paroxysms at onset that continued along the course of the syndrome. In three, in addition to the diffuse paroxysms, focal spikes appeared later. From a clinical point of view, other features were otherwise unremarkable. Diffuse spike-and-wave discharges were observed in all patients when awake and during sleep (100%). Later, three children also had focal spikes during sleep, which were occipital in one, frontal in one, and temporo-occipital in the remaining patient. Spikes were activated by sleep in all three cases. During disease evolution, no particular electroclinical pattern was observed. Two patients who received clobazam and carbamazepine, respectively, did not respond well to the drugs and valproic acid was added with excellent seizure control. Outcome was good. We present evidence that patients with Panayiotopoulos syndrome may have diffuse discharges at onset as the sole EEG manifestation, which last throughout the course of the syndrome. In some, focal paroxysms developed later. The course was benign. In our group of patients, clinical features and evolution were similar to those of typical cases of Panayiotopoulos syndrome.

    ABSTRACT: To (1) summarize published, peer-reviewed literature about the incidence and prevalence of epilepsy in children from developed and developing countries around the world, and (2) discuss problems in defining aetiologies of epilepsy in children, and distinguish between seizures and epilepsy. Review of selected literature with particular attention to systematic reviews. The incidence of epilepsy in children ranges from 41-187/100,000. Higher incidence is reported from underdeveloped countries, particularly from rural areas. The incidence is consistently reported to be highest in the first year of life and declines to adult levels by the end of the first decade. The prevalence of epilepsy in children is consistently higher than the incidence and ranges from 3.2-5.5/1,000 in developed countries and 3.6-44/1,000 in underdeveloped countries. Prevalence also seems highest in rural areas. The incidence and prevalence of specific seizure types and epilepsy syndromes is less well documented. In population-based studies, there is a slight, but consistent, predominance of focal seizures compared with generalized seizures. Only about one third of children with epilepsy can be assigned to a specific epilepsy syndrome, as defined by the most recently proposed system for organization of epilepsy syndromes. The incidence and prevalence of epilepsy in children appears to be lower in developed countries and highest in rural areas of underdeveloped countries. The reasons for these trends are not well established. Although focal seizures predominate, the incidence and prevalence of specific epilepsy syndromes is not well documented.

    ABSTRACT: Two elderly men, with previous history of cerebrovascular disease, were admitted to the emergency department due to focal motor status epilepticus with persistent myoclonic jerks of one side of the body. In both cases, the clinical picture evolved into a unilateral and isolated arrhythmic myoclonus of the abdominal muscles with preserved consciousness. These involuntary movements resolved with antiepileptic drugs. Although cerebrovascular disease is one of the most common causes of epilepsia partialis continua, reported cases in the literature with predominant abdominal involvement have a different aetiology. The neuroimaging and electroencephalographic findings showed a wide spectrum of different localizations and aetiologies associated with this particular type of epileptic seizure. Indeed, the pathophysiology of focal motor seizures involving the abdominal muscles is still a matter of discussion. In our second case, we present a patient with epilepsia partialis continua of the abdominal wall with an occipital focus, which, to the best of our knowledge, has not been previously reported.

    ABSTRACT: Various movement disorders have been described following hypoxic-ischaemic brain injury. Here, we present a 72-year-old female patient who developed periodic opening and upward deviation of the eyes as an isolated clinical finding, within 24 hours after cardio-pulmonary arrest. These movements were accompanied by burst-suppression on EEG, and both clinical and electrophysiological findings were suppressed 18 hours after intravenous levetiracetam infusion. The strictly periodic nature of both EEG discharges and eye opening with vertical deviation suggest a cause due to either activation of a subcortical/brainstem pacemaker reciprocally stimulating the cortex, or, alternatively, post-anoxic burst activity of viable cortical neural networks, somehow stimulating the relevant oculomotor nuclei. Together with previous similar cases, our case expands the spectrum of post-resuscitation myoclonus syndromes with the addition of this rare isolated oculopalpebral subtype.

    ABSTRACT: We investigated the anatomo-electro-clinical features and clinical outcome of surgical resections strictly confined to the parietal lobe in 40 consecutive patients who received surgery for pharmacoresistant seizures. The population was subcategorized into a paediatric (11 subjects; mean age at surgery: 7.2+/-3.7 years) and an adult group (29 patients; mean age at surgery: 30+/-10.8 years). The paediatric group more frequently exhibited personal antecedents, neurological impairment, high seizure frequency, and dysplastic lesions. Nonetheless, compared with adults, children had better outcome and more frequently reached definitive drug discontinuation after surgery. After a mean follow-up of 9.4 years (range: 3.1-16.7), 30 subjects (75%) were classified as Engel Class I. The presence of multiple types of aura in the same patient, as well as a high incidence of secondary generalization, represented a characteristic feature of parietal seizures and did not correlate negatively with surgical outcome. A total resection of the epileptogenic zone and a localizing/regional interictal EEG were statistically significant predictive factors of outcome. Intracerebral investigation, performed in 55% of cases, contributed to complete tailored resections of the epileptogenic area and determination of prognosis. Frequent subjective manifestations of parietal lobe seizures, such as vertiginous, cephalic and visual-moving sensations, underscore their potential misdiagnosis as non-epileptic events.

    ABSTRACT: Ictal vocalizations in the form of both articulate speech and non-speech vocalizations have been described in focal epilepsies, with seizures originating mainly from the frontal and temporal lobe, however, this phenomenon has not been described in generalized epilepsies. We report the case of an adolescent boy with juvenile-onset generalized epilepsy who presented with ictal "ovine vocalizations" (resembling the bleating of sheep). The ictal EEG revealed a clear correlate of vocalizations with time-locked generalized spikes and polyspike discharges. The 3T cerebral MRI ruled out any focal lesion. The boy is currently seizure-free under valproic acid, after twelve months of follow-up. We conclude that ictal non-speech vocalizations may be observed not only in focal or structural epilepsies, but also in generalized epilepsies; the exact underlying mechanism of this phenomenon needs to be further delineated.

    ABSTRACT: Clinicians trained to interpret EEG in Africa are scarce. The region is challenged by inadequate access to healthcare professionals and a significant burden of disease, with the result that trained neurophysiologists and epileptologists may not be viewed as an immediate priority. However, approaches, specific to the African context, could be adopted to enable safe practice of basic EEG interpretation. Educational guidelines for the interpretation of paediatric studies, relevant to the region, are lacking. As a result, a handbook targeting this training need was developed and a pilot study undertaken to assess the efficacy of this tool to improve EEG-reporting skills for clinicians at a basic level. Eleven health practitioners, who manage children with epilepsy, from various African countries, were recruited. The group analysed selected EEGs before and after reading a training manual (the handbook). A survey was conducted on how useful the participants found the handbook. There was a trend (p<0.06) supporting improvement in the ability to analyse EEGs following reading of the handbook. The doctors who had one-on-one tutoring, in addition to access to the handbook, did significantly better in most EEG-reporting variables (p<0.01). The handbook was found to be a viable tool to promote EEG interpretation in the African setting, where foundation skills are needed. However, optimal outcomes were evident with additional individual tutoring, as well as on-going support to maintain skills. This curriculum will be adapted into a post-graduate qualification intended to generate clinicians with key basic EEG skills, but not fully trained electrophysiologists. Currently, in the African setting, for maximum impact on patient care, this approach is considered the most likely to have the furthest reach.

    ABSTRACT: Epilepsy surgery is a well-accepted treatment for drug-resistant epilepsy. The success of the epilepsy surgery depends upon an appropriate presurgical evaluation process which should ensure the selection of suitable patients who are likely to become seizure-free following surgery without any unacceptable deficit. The two basic goals of the presurgical evaluation are the accurate localization and delineation of the extent of the epileptogenic zone, and its complete and safe resection. The process of the presurgical evaluation requires a multimodality approach wherein each modality provides unique and complimentary information which is combined with the information provided by other modalities to generate a hypothesis with regard to the likely epileptogenic zone. The basic modalities for the presurgical evaluation are clinical history, long-term video-EEG recording, high-resolution MRI, and neuropsychological evaluation. The additional modalities include functional imaging studies, electrical and magnetic source imaging, functional MRI, and intracranial monitoring. Each modality has its own limitations and the information provided by none of them is absolute. Hence, a concordance among the different modalities is the key to surgical success. The presurgical evaluation is a step-wise process starting form the most basic and most reliable tests and progressing to more complex and invasive modalities. The number of tests required varies according to the complexity involved and may include very basic minimum investigations in a given case, to the use of all the available investigations in more complex cases. The proper selection of various investigations and their accurate interpretation at each stage is required to ensure a successful outcome. In this article, we intend to review some of these basic concepts of presurgical evaluation and epilepsy surgery, and try to provide a frame work of the presurgical evaluation process.

    ABSTRACT: Although adrenocorticotropic hormone is the most commonly used treatment for infantile spasms in the United States, the optimal regimen for this indication is not known. The purpose of this study was to elucidate the optimal adrenocorticotropic hormone treatment duration. We conducted a retrospective chart review of response to adrenocorticotropic hormone among all patients with infantile spasms managed at our institution from January 2009 to September 2013. Treatment response was defined as clinical remission for greater than or equal to 28 days starting at any point within the adrenocorticotropic hormone course and remission of hypsarrhythmia (or definite EEG improvement if hypsarrhythmia was absent at baseline). For responders, the diagnostic and post-treatment EEG tracings were reviewed. Electroclinical remission was achieved in 21 of 39 patients (54%) receiving adrenocorticotropic hormone, including 11/25 (44%) receiving a long course (typically 12 weeks) and 10/14 (71%) receiving a short course (typically four weeks). The mean time to clinical remission was 5.8 days (median: 5 days; range: 1-20 days). Only one patient responded beyond two weeks of treatment. This study provides Class IV evidence that among patients with infantile spasms, the response to adrenocorticotropic hormone is most often determined early in the treatment course. Given the importance of rapid remission, clinicians should consider adding or changing treatment if infantile spasms do not resolve within two weeks of adrenocorticotropic hormone initiation. Further study is needed to determine the optimal adrenocorticotropic hormone regimen for infantile spasms.

    ABSTRACT: Myoclonic status epilepticus or mixed absence-myoclonic status is uncommon in juvenile myoclonic epilepsy (JME), often precipitated by sleep deprivation, withdrawal of medication, or inadequate antiepileptic drugs (Thomas et al., 2006; Crespel et al., 2013). Such episodes respond well to benzodiazepines or valproate ( Crespel et al., 2013 ). We present the video-EEG of a 24-year-old woman with JME and bipolar disorder. She had a confusional state five days after withdrawal of clonazepam (14 mg/d) and introduction of oxazepam (200 mg/d), followed by catatonic stupor with subtle myoclonus of the face and the arms. The EEG showed absence status (figures 1, 2), which stopped after IV injection of clonazepam (1 mg) (figure 3). Consciousness returned to normal [Published with video sequences and figures].

    ABSTRACT: Aim. In drug-responsive epilepsy patients, treatment non-compliance is a major factor in seizure recurrence, but adherence to prescribed regimens following epilepsy surgery has not been examined. We measured adherence to prescribed antiepileptic drugs (AEDs) after epilepsy surgery and investigated factors influencing treatment non-compliance. Methods. Postsurgical epilepsy patients (n=214) were monitored for 18.1±8.1 months. Adherence was measured using the Medication Possession Ratio (MPR) self-report questionnaire, with MPR<0.8 defined as non-adherence. Results. According to the MPR, 58 patients (27.1%) were non-adherent after surgery. There were no differences in demographic and clinical variables, such as age (p=0.057, t =-1.925), duration of illness (p=0.597, t=0.530), gender ratio (p=0.714, χ(2)=0.134), and place of residence (urban vs. rural; p=0.874, χ(2)=0.025), between adherent and non-adherent patients. Moreover, adherence was not related to surgical outcome as evaluated by the Engel classification (p=0.635, χ(2)=1.628) or to the types of AEDs after surgery (p=0.165, χ(2)=6.530). The most common reasons for non-adherence were seizure-free status for an extended period (26.5%), forgetfulness (19.1%), and an inability to buy the drugs locally (18.6%). Conclusion. Adherence to AEDs is improved after epilepsy surgery compared to presurgical estimates, but is still a common and serious problem. Targeted postsurgical management programs and communication strategies are necessary to improve adherence to AEDs after epilepsy surgery.
