    Childhood absence epilepsy (CAE) and benign childhood epilepsy with centrotemporal spikes (BCECTS), or benign rolandic epilepsy (BRE), are the most common forms of childhood epilepsy. CAE and BCECTS are well-known and clearly defined syndromes; although they are strongly dissimilar in terms of their pathophysiology, these functional epileptic disturbances share many features such as similar age at onset, overall good prognosis, and inheritance factors. Few reports are available on the concomitance of CAE and BCECTS in the same patients or the later occurrence of generalized epilepsy in patients with a history of partial epilepsy. In most cases described in the literature, absence seizures always started after the onset of benign focal epilepsy but the contrary has never occurred yet. We describe two patients affected by idiopathic generalized epileptic syndrome with typical absences, who experienced BCECTS after remission of seizures and normalization of EEG recordings. While the coexistence of different seizure types within an epileptic syndrome is not uncommon, the occurrence of childhood absence and BCECTS in the same child appears to be extremely rare, and this extraordinary event supports the hypothesis that CAE and BCECTS are two distinct epileptic conditions. However, recent interesting observations in animal models suggest that BCECTS and CAE could be pathophysiologically related and that genetic links could play a large role.

    Introduction Childhood absence epilepsy is an epilepsy syndrome responding relatively well to the ketogenic diet with one-third of patients becoming seizure-free. Less restrictive variants of the classical ketogenic diet, however, have been shown to confer similar benefits. Beneficial effects of high fat, low-carbohydrate diets are often explained in evolutionary terms. However, the paleolithic diet itself which advocates a return to the human evolutionary diet has not yet been studied in epi...

Seizure frequency and treatment, however, did not influence memory performance. This study indicates that children with FLE show greater risk of developing memory deficits than children with CAE or BECTS, thus highlighting the importance of assessing also memory functions in frontal lobe epilepsy.

    2014-08-01

    This chapter covers the syndromes of benign epilepsy with centrotemporal spikes (BECTS), nonlesional focal epilepsy in otherwise normal children (NLFN), and the genetic generalized epilepsies. BECTS is an epilepsy syndrome that always enters terminal remission before the general age of a planned transition of adolescents. This is also the case for the majority (65%) of those with childhood absence epilepsy (CAE). Approximately 15% of patients with CAE who initially remit during their childhood years later develop juvenile myoclonic epilepsy (JME) as teenagers. They will have many issues for continuing medical care and transition, because their seizure disorder generally persists into adulthood. A significant minority of NLFN (~35%) and most patients with JME continue to have active epilepsy into adulthood. In addition, CAE, JME, and NLFN patients are at risk of a number of significant adverse social outcomes that require ongoing advice and counseling.

    Full Text Available Objective To observe the alterations of resting-state brain functional networks in childhood absence epilepsy (CAE using resting-state functional magnetic resonance imaging (fMRI analysis, and to explore the cognitive disorders of children in epileptic seizures. Methods According to case selection criteria, 12 children with absence seizure were selected, from whom 17 fMRI data with generalized slow-wave discharges (GSWD and the matched data without discharges were collected by using electroencephalogram (EEG-fMRI synchronization. Independent component analysis was used to investigate the alterations in different states of 7 resting-state networks including the thalamus, default-mode network, dorsal attention network, central execution network and perceptive networks. Results Paired t-test and correlation analysis were used for statistical analysis. The thalamus showed increased coherence of brain activity in GSWD state, and the increased coherence was positively correlated with the durations of GSWD (r = 0.890, P = 0.000. The default-mode network (r = - 0.706, P = 0.000, dorsal attention network (r = - 0.829, P = 0.000 and central execution network (r = - 0.905, P = 0.000, which dealt with high -grade cognitive functions, showed decreased coherence, and the brain activity coherence in these networks were negatively correlated with GSWD durations. However, none of low-grade perceptive networks was found to have significant alteration in GSWD state. Conclusion The increased coherence of brain activity in the thalamus may be associated with the generation of GSWD in childhood absence epilepsy. Besides the default brain function, the processes of attention and cognitive execution may also be impaired in childhood absence epilepsy, while low-grade perceptive functions may not be greatly impacted. This study may contribute to the understanding of pathophysiological mechanism of impaired consciousness in childhood absence epilepsy.

  16. Epilepsy with myoclonic absences.

    1994-04-01

    The cases are described of eight children, five of them girls, who had epilepsy with myoclonic absences. The mean age of onset was 4.9 years. Brief episodes of loss of awareness with bilateral clonic jerking of the upper limbs were associated with rhythmic 3 cycles/second spike-wave discharges on electroencephalogram. Generalised tonic-clonic or astatic seizures, or both, also occurred in seven patients. All now have learning difficulties, and seven have behavioural problems. Conventional treatment for absences was effective in only two children. Of six patients treated with lamotrigine, five have improved substantially, but only one is in sustained complete remission. One recently diagnosed patient continues to have frequent myoclonic absences. As the response to treatment and long term outcome are much poorer, it is important to differentiate myoclonic absences from typical childhood absence epilepsy.

  18. Functional study of NIPA2 mutations identified from the patients with childhood absence epilepsy.

    Han Xie

    Full Text Available Recently many genetic mutations that are associated with epilepsy have been identified. The protein NIPA2 (non-imprinted in Prader-Willi/Angelman syndrome region protein 2 is a highly selective magnesium transporter encoded by the gene NIPA2 in which we have found three mutations (p.I178F, p.N244S and p.N334_E335insD within a population of patients with childhood absence epilepsy (CAE. In this study, immunofluorescence labeling, inductively coupled plasma-optical emission spectroscopy (ICP-OES, MTT metabolic rate detection and computational modeling were utilized to elucidate how these mutations result in CAE. We found in cultured neurons that NIPA2 (wild-type proteins were localized to the cell periphery, whereas mutant proteins were not effectively trafficked to the cell membrane. Furthermore, we found a decrease in intracellular magnesium concentration in the neurons transfected with mutant NIPA2, but no effect on the survival of neurons. To understand how low intracellular magnesium resulted in hyperexcitability, we built and analyzed a computational model to simulate the effects of mutations. The model suggested that lower intracellular magnesium concentration enhanced synaptic N-methyl-D-aspartate receptor (NMDAR currents. This study primarily reveals that a selective magnesium transporter NIPA2 may play a role in the pathogenesis of CAE.

    2003-08-01

    Absence seizures may be seen in a variety of epileptic syndromes in childhood. Identification of the specific syndrome is important to determine medical prognosis. With childhood absence epilepsy, approximately two thirds of children can be expected to enter long-term remission, while in juvenile absence epilepsy, seizure control is often achieved, however, lifelong treatment is usually required. Other absence syndromes have a poorer prognosis, with lower rates of seizure control and remission. Psychosocial outcome is often poor, even in patients with more benign forms of absence epilepsy. Remission of epilepsy does not preclude psychosocial morbidity.

    1991-11-01

    Absence epilepsy was studied in a Swedish population, aged 0-15 years, in 1978-1982. Cases were selected by electroencephalographic criteria. In the 134 children with 3 Hz spike-and-wave discharges, 97 (72.4%) had absences alone or in combination with generalized tonic-clonic seizures (grand mal): 56 had absences alone, 31 absences followed by grand mal, and 10 started with initial grand mal. Two distinct groups could be discerned: 1) childhood absence epilepsy: onset before the age of 12, with a quick response to therapy, little or no risk of grand mal, and a high remission rate; 2) juvenile absence epilepsy: onset at the age of 12 or later, a very high risk of grand mal, and usually a good response to therapy, but a high risk of relapses at withdrawal. This classification of absence epilepsy into subgroups may be useful for prognostic guidelines.

  2. Differentiating Interictal and Ictal States in Childhood Absence Epilepsy through Permutation Rényi Entropy

    2015-07-01

    Full Text Available Permutation entropy (PE has been widely exploited to measure the complexity of the electroencephalogram (EEG, especially when complexity is linked to diagnostic information embedded in the EEG. Recently, the authors proposed a spatial-temporal analysis of the EEG recordings of absence epilepsy patients based on PE. The goal here is to improve the ability of PE in discriminating interictal states from ictal states in absence seizure EEG. For this purpose, a parametrical definition of permutation entropy is introduced here in the field of epileptic EEG analysis: the permutation Rényi entropy (PEr. PEr has been extensively tested against PE by tuning the involved parameters (order, delay time and alpha. The achieved results demonstrate that PEr outperforms PE, as there is a statistically-significant, wider gap between the PEr levels during the interictal states and PEr levels observed in the ictal states compared to PE. PEr also outperformed PE as the input to a classifier aimed at discriminating interictal from ictal states.

  6. Predictors of intractable childhood epilepsy

    International Nuclear Information System (INIS)

    To determine the prognosis of seizures in epileptic children and identify early predictors of intractable childhood epilepsy. All children (aged 1 month to 16 years) with idiopathic or cryptogenic epilepsy who were treated and followed at the centre during the study period were included. The patients who had marked seizures even after two years of adequate treatment were labeled as intractable epileptics (cases). Children who had no seizure for more than one year at last follow-up visit were the controls. Adequate treatment was described as using at least three anti-epileptic agents either alone or in combination with proper compliance and dosage. Records of these patients were reviewed to identify the variables that may be associated with seizure intractability. Of 442 epileptic children, 325 (74%) intractable and 117 (26%) control epileptics were included in the study. Male gender (OR=3.92), seizures onset in infancy >10 seizures before starting treatment (OR=3.76), myoclonic seizures (OR=1.37), neonatal seizures (OR=3.69), abnormal EEG (OR=7.28) and cryptogenic epilepsy (OR=9.69) and head trauma (OR=4.07) were the factors associated with intractable epilepsy. Seizure onset between 5-7 years of age, idiopathic epilepsy, and absence seizures were associated with favourable prognosis in childhood epilepsy. Intractable childhood epilepsy is expected if certain risk factors such as type, age of onset, gender and cause of epilepsy are found. Early referral of such patients to the specialized centres is recommended for prompt and optimal management. (author)

    GLUT-1 deficiency syndrome (GLUT-1 DS) is a disorder of cerebral glucose transport associated with early infantile epilepsy and microcephaly. We report two boys who presented with refractory absence epilepsy associated with hypoglycorrhachia, both of whom have genetically confirmed GLUT-1 DS. We propose that these children serve to expand the phenotype of GLUT-1 DS and suggest that this condition should be considered as a cause of refractory absence seizures in childhood.

    Background Childhood absence epilepsy (CAE) is one of the most frequently recognized syndromes among the idiopathic generalized epilepsies (IGEs). CAE is considered to be a genetic disease, with a possible polygenic inheritance pattern. The genes responsible for CAE have not been identified yet. The object of this study was to investigate whether or not CAE is associated with the gene encoding the gamma-aminobutyric acid (GABA) type-A receptor subunits α5 (GABRA5) and β3 (GABRB3) in a Chinese population. Methods Five microsatellite DNA repeats, 69CA, 85CA, 155CA1, 155CA2, and A55CA1, adjoining chromosome 15q11-q13, were used as genetic markers. Both case-control study and transmission/disequilibrium tests (TDTs), as well as fluorescence-based semi-automated genotyping techniques, were used in 90 CAE patient-mother-father trios and 100 normal controls of Han ethnicity to conduct association analysis. Results The frequencies of allele 5 of 69CA, alleles 2 and 8 of 85CA, alleles 6 and 7 of 155CA1, allele 2 of 155CA2, and alleles 1 and 11 of A55CA1 were significantly higher in CAE patients than in normal controls. To prevent spurious associations arising from population admixture, we further conducted TDT tests in the 90 CAE trios. The results of TDT analysis further suggested that microsatellite DNA repeats 85CA, 155CA1, and 155CA2 were associated with CAE.Conclusions GABA type-A receptor subunit genes GABRA5 and GABRB3 may be either directly involved in the etiology of CAE in the Chinese population or in linkage disequilibrium with disease-predisposing sites.

    Five unrelated patients are described with the clinical and electrical features of eyelid myoclonia with absences (EMA). In this syndrome brief, typical absences occur with rapid eyelid myoclonia associated with retropulsive movements of the eyeballs and occasionally of the head. The seizures are of shorter duration than in childhood absence epilepsy, and are accompanied by less profound impairment of consciousness. The electroencephalogram demonstrates high amplitude discharges consisting of spikes, multiple spikes and slow waves at a fluctuating frequency of 3-5 Hz and following eye closure, which disappear in darkness. Photosensitivity is also seen. Onset is in early childhood and EMA appears to persist into adult life. Treatment is sodium valproate in combination with either ethosuximide or a benzodiazepine. On the basis of the clinical features, EEG findings, and the response to treatment and prognosis, it is suggested that EMA be classified as a specific epilepsy syndrome. PMID:8270934

    Full Text Available Treatment of epileptic encephalopathies can be very challenging as most anticonvulsant drugs fail to achieve good seizure control. Steroids are disease modifying as well as anticonvulsant in these conditions. Though steroids are accepted as the first-line treatment for infantile spasms, there are many unanswered questions with regard to the preparation, dose and duration of treatment. In this review a re-exploration of the literature is attempted. Putative mechanism of action of steroids in infantile spasms is also discussed. As steroids are being increasingly used in other epileptic encephalopathies and Rasmussen′s encephalitis, a brief discussion on the role of steroids in these conditions is attempted. The review ends with the discussion on newer neuroactive steroids in the management of epilepsy.

    The electrographic hallmark of childhood absence seizures is 3 Hz generalized spike and wave discharges; however, there is likely a focal thalamic or cortical onset that cannot be detected using scalp electroencephalography (EEG). The purpose of this study was to study the earliest preictal changes in children with absence epilepsy. In this report, magnetoencephalography recordings of 44 absence seizures recorded from 12 children with drug-naïve childhood absence seizures were used to perform time frequency analysis and source localization prior to the onset of the seizures. Evidence of preictal magnetoencephalography frequency changes were detected a mean of 694 ms before the initial spike on the EEG. A consistent pattern of focal sources was present in the frontal cortex and thalamus during this preictal period, but source localization occurred synchronously so that independent activity between the 2 structures could not be distinguished.

    This study sought to present clinical and outcome data of patients with idiopathic childhood occipital epilepsy of Gastaut, to validate previously reported characteristics of this epilepsy. The study group was comprised of 12 affected children (three boys and nine girls), with a median age of onset at 10.3 years. Common ictal manifestations included elementary visual hallucinations (75.0%), blindness or blurring of vision (50.0%), headache (50.0%), and secondarily generalized tonic-clonic seizures (58.3%). Interictal electroencephalography revealed occipital spike-wave paroxysms reactive to eye closure and opening in all patients, accompanied by spike-wave activity in the extra-occipital areas in four (33.3%), and by generalized spike-wave discharges in two (16.7%). One patient exhibited the onset of occipital lobe seizures 1 year after manifesting absence epilepsy. Seizure remission occurred in 81.8% of cases, in half of which medication was discontinued by late adolescence. This study confirmed the previously delineated electroclinical features of epilepsy syndrome, with additional aspects including the frequent association of generalized tonic-clonic seizures and atypical evolution from childhood absence epilepsy.

  8. Genes and molecular mechanisms involved in the epileptogenesis of idiopathic absence epilepsies.

    2012-03-01

    Idiopathic absence epilepsies (IAE), that have high prevalence particularly among children and adolescents, are complex disorders mainly caused by genetic factors. Childhood absence epilepsy and juvenile absence epilepsy are among the most common subtypes of IAEs. While the role of ion channels has been the primary focus of epilepsy research, the analysis of mutation and association in both patients with absence epilepsies and animal models revealed the involvement of GABA receptors and calcium channels, but also of novel non-ion channel proteins in inducing spike wave discharges (SWD). Functional studies on a mutated variant of these proteins also support their role in the epileptogenesis of absence seizures. Studies in animal models point to both the thalamus and cortex as the origin of SWDs: the abnormalities in the components of these circuits leading to seizure activity. This review examines the current research on mutations and susceptibility alleles determined in the genes that code for the subunits of GABA receptors (GABRG2, GABRA1, GABRB3, GABRA5, GABA(B1) and GABA(B2)), calcium channels (CACNA1A, CACNA1G, CACNA1H, CACNA1I, CACNAB4, CACNAG2 and CACNG3), and novel non-ion channel proteins, taking into account the results of functional studies on these variants.

    While epidemiological data suggest a female prevalence in human childhood- and adolescence-onset typical absence epilepsy syndromes, the sex difference is less clear in adult-onset syndromes. In addition, although there are more females than males diagnosed with typical absence epilepsy syndromes, there is a paucity of studies on sex differences in seizure frequency and semiology in patients diagnosed with any absence epilepsy syndrome. Moreover, it is unknown if there are sex differences in the prevalence or expression of atypical absence epilepsy syndromes. Surprisingly, most studies of animal models of absence epilepsy either did not investigate sex differences, or failed to find sex-dependent effects. However, various rodent models for atypical syndromes such as the AY9944 model (prepubertal females show a higher incidence than prepubertal males), BN model (also with a higher prevalence in males) and the Gabra1 deletion mouse in the C57BL/6J strain offer unique possibilities for the investigation of the mechanisms involved in sex differences. Although the mechanistic bases for the sex differences in humans or these three models are not yet known, studies of the effects of sex hormones on seizures have offered some possibilities. The sex hormones progesterone, estradiol and testosterone exert diametrically opposite effects in genetic absence epilepsy and pharmacologically-evoked convulsive types of epilepsy models. In addition, acute pharmacological effects of progesterone on absence seizures during proestrus are opposite to those seen during pregnancy. 17β-Estradiol has anti-absence seizure effects, but it is only active in atypical absence models. It is speculated that the pro-absence action of progesterone, and perhaps also the delayed pro-absence action of testosterone, are mediated through the neurosteroid allopregnanolone and its structural and functional homolog, androstanediol. These two steroids increase extrasynaptic thalamic tonic GABAergic

    Full Text Available Introduction. Carbamazepine can lead to aggravation of epileptic seizures in generalized epilepsies (primary or secondary with clinical manifestations of absence (typical or atypical and/or myoclonic seizures. However, some focal epilepsies can be also aggravated by the introduction of carbamazepine. Case report. We presented a 10-year-old boy born after a complicated and prolonged delivery completed by vacuum extraction, of early psychomotor development within normal limits. At the age of 8 years he had the first epileptic seizure of simple occipital type with generalization and urination. Brain magnetic resonance imaging (MRI showed focal cortical reductions in the left parietal and occipital regions. Interictal EEG recorded slowed basic activities above the posterior regions of the left hemisphere, with intermittent occurrence of occipital sharp waves and bioccipital sharp and slow-wave complexes. Initially, treatment with valproate was administered; however, the addition of carbamazepine into therapy induced aggravation of seizures and EEG findings, changed behavior and poor performance at school. By withdrawal of carbamazepine the condition improved both clinically and in EEG findings. Conclusion. Childhood occipital epilepsy lesions show deterioration due to carbamazepine, which if administered induces aggravation of seizures, behavior changes, cognition with occurrence of long-term bilateral discharges, and posterior sharp and slow wave high amplitude complexes recorded by EEG.

  19. Impact of Childhood Epilepsy on the Family

    Full Text Available Whole family is affected when an illness appears in the family or when there is an uncertainty regarding the health of a member. Symptoms, therapy, course of the disorder, constraint of the daily activities and long term effects of childhood chronic diseases deeply impact health and structure of the families. Diagnosis of a chronic disease in children presents as a significant psychological and psychosocial risk factor to the parents and other family members. Despite these known facts, psychosocial problems of parents of epileptic children are often ignored and not even questioned. These parents frequently have to leave their jobs or ask for their elderly relatives to look after their children. This situation could lead to major financial and social problems, weakening in intrafamilial communication and disruption in family harmony. Childhood epilepsy brings a great strain on family’s resources as other chronic diseases do and alter the life of significant others. According to biopsychosocial model, schemas in family relations influence the psychological process of the family members while the biopsychosocial process of the sick individual affect the functionality of the family. In other words, epilepsy affects not only the sick individual but also the family union. The family has to face many problems after definite diagnosis of epilepsy. Majority of the studies conducted on this issue mainly focused on the quality of life and family relations of the sick child, whereas only a few studies searched for possible burden and resulting problems of family members caused by epilepsy. Physicians in charge should not only focus on physical and mental health of the sick children but also on the problems of other members in the family bearing in mind psychosocial influences of the disorder on them. Additionally, preventive methods should be administered to protect the family from developing mental health problems. A multidiscipline training program

    2014-12-01

    Full Text Available Aim: The aim of this study was to evaluate the cognitive and visual perceptive functions in children with childhood epilepsy with occipital paroxysms (CEOP. Material and Method: Hospital charts of children ages 1 to 18 years who admitted to pediatric neurology out-patient clinic between 2009 and 2010 were reviewed. Twenty one children with a diagnosis of CEOP were identified. Sixteen of these children who accepted to include the study were evaluated with neuropsychological tests. Results: Two of five patients who were evaluated with Denver developmental screening test were found to have lower scores than their reference standards. Remaining 11 patients were evaluated with Wechsler Scales of Intelligence tests, 4 were mildly mental retarded and 1 had null intelligence. Eleven patients were also evaluated with Bender Gestalt Visual Motor Test and 7of them had disturbances in visual perception. Reading speed and writing norm tests were applied to 9 literate patients and 7 of them showed slower reading ability and writing ability was found worse in 6 patients. Discussion: The absence of neurological and neuropsylogical deficits has long been considered as a prerequisite for diagnosis of benign childhood partial epilepsies. However, only a few studies describing the cognitive profile of patients with CEOP have been published. The present study has demonstrated that the patients with CEOP had varying degree of cognitive dysfunction and disturbance in visual perception. In order to provide appropriate intervention, cognitive functions should be assessed in children with CEOP.

    Although stress can alter the susceptibility of patients and animal models to convulsive epilepsy, little is known about the role of stress and glucocorticoid hormones in absence epilepsy. We measured the basal and acute stress-induced (foot-shocks: FS) concentrations of corticosterone in WAG/Rij rats, non-epileptic inbred ACI rats and outbred Wistar rats. The WAG/Rij strain is a genetic model for absence epilepsy and comorbidity for depression, which originates from the population of Wistar rats and, therefore, shares their genetic background. In a separate experiment, WAG/Rij rats were exposed to FS on three consecutive days. Electroencephalograms (EEGs) were recorded before and after FS, and the number of absence seizures (spike-wave-discharges, SWDs) was quantified. Both WAG/Rij rats and ACI rats exhibited elevated basal levels of corticosterone and a rapid corticosterone increase in response to acute stress. The WAG/Rij rats also displayed the most rapid normalization of corticosterone during the recovery phase compared to that of ACI and Wistar rats. FS had a biphasic effect on SWDs; an initial suppression was followed by an aggravation of the SWDs. By the third day, this aggravation of seizures was present in the hour preceding FS. This increase in SWDs may arise from anticipatory stress about the upcoming FS. Together, these results suggest that the distinct secretion profile of corticosterone found in WAG/Rij rats may contribute to the severity of the epileptic phenotype. Although the acute stressor results in an initial suppression of SWDs followed by an increase in SWDs, stress prior to a predictable negative event aggravates absences.

    2015-01-01

    Full Text Available System epilepsy is an emerging concept interpreting major nonlesional epilepsies as epileptic dysfunctions of physiological systems. I extend here the concept of reflex epilepsy to epilepsies linked to input dependent physiological systems. Experimental and clinical reseach data were collected to create a coherent explanation of underlying pathomechanism in AE and NFLE. We propose that AE should be interpreted as epilepsy linked to the corticothalamic burst-firing mode of NREM sleep, released by evoked vigilance level oscillations characterized by reactive slow wave response. In the genetic variation of NFLE the ascending cholinergic arousal system plays an essential role being in strong relationship with a gain mutation of the nicotinic acethylcholin receptors, rendering the arousal system hyperexcitable. I try to provide a more unitary interpretation for the variable seizure manifestation integrating them as different degree of pathological arosuals and alarm reactions. As a supporting hypothesis the similarity between arousal parasomnias and FNLE is shown, underpinned by overlaping pathomechanism and shared familiarity, but without epileptic features. Lastly we propose that both AE and NFLE are system epilepsies of the sleep-wake system representing epileptic disorders of the antagonistic sleep/arousal network. This interpretation may throw new light on the pathomechanism of AE and NFLE.

    2011-12-01

    Epilepsy with myoclonic absences (EMA) is a rare form of generalized epilepsy occurring in childhood and is often difficult to treat. The underlying etiology of EMA is unknown in the majority of patients. Herein, we describe a patient with EMA and intellectual disability who carries a de novo balanced translocation: t(6;22)(p21.32;q11.21). We mapped the translocation breakpoints by fluorescence in situ hybridization (FISH), and the breakpoint at 6p21.32 was found to truncate the N-methyl-d-aspartate (NMDA)-receptor associated gene SYNGAP1. The breakpoint at 22q11.21 was within a highly variable region without known protein-coding genes. Mutations of SYNGAP1 are associated with nonsyndromal intellectual disability (NSID). Two-thirds of the patients described so far also have generalized epilepsy. This finding, together with our report, suggests that dysfunction of SYNGAP1 contributes to the development of generalized epilepsy, including EMA.

    Parental attitude and adjustment were examined in 20 epileptic children (ages 6.8-16.6 yrs), using semi-structured interview. The results indicated that parental understandings of epilepsy were generally poor and incorrect. Fifteen (75%) of 20 parents had their own interpretations of causality and 19 (95%) had unrealistic hope for early and complete cure. Parents tended to overprotect and overrestrict their children. Sixteen (80%) concealed the illness for fear of social prejudice, therefore the social support systems were generally poorly utilized. As in other chronic diseases, all parents went through feelings of shock, denial, anger, guilt, fear, anxiety and depression. Family relationships were not affected much, however, poor communications were commonly found between parents and children. Thirteen (65%) parents never talked to their children about epilepsy. We concluded that parents of epileptic children showed negative attitudes toward their children and had difficulties in their psychosocial adjustment probably related to social stigmata and misunderstanding of the illness. Therefore, communication between physician and parents in both medical and psychosocial aspects should be encouraged. PMID:2275364

    Behavioural, neurological, and genetic similarities exist in epilepsies, their psychiatric comorbidities, and various psychiatric illnesses, suggesting common aetiological factors. Rodent models of epilepsy are used to characterize the comorbid symptoms apparent in epilepsy and their neurobiological mechanisms. The present study was designed to assess Pavlovian fear conditioning and latent inhibition in a polygenetic rat model of absence epilepsy, i.e. Genetic Absence Epilepsy Rats from Strasbourg (GAERS) and the non-epileptic control (NEC) strain. Electrophysiological recordings confirmed the presence of spike-wave discharges in young adult GAERS but not NEC rats. A series of behavioural tests designed to assess anxiety-like behaviour (elevated plus maze, open field, acoustic startle response) and cognition (Pavlovian conditioning and latent inhibition) was subsequently conducted on male and female offspring. Results showed that GAERS exhibited significantly higher anxiety-like behaviour, a characteristic reported previously. In addition, using two protocols that differed in shock intensity, we found that both sexes of GAERS displayed exaggerated cued and contextual Pavlovian fear conditioning and impaired fear extinction. Fear reinstatement to the conditioned stimuli following unsignalled footshocks did not differ between the strains. Male GAERS also showed impaired latent inhibition in a paradigm using Pavlovian fear conditioning, suggesting that they may have altered attention, particularly related to previously irrelevant stimuli in the environment. Neither the female GAERS nor NEC rats showed evidence of latent inhibition in our paradigm. Together, the results suggest that GAERS may be a particularly useful model for assessing therapeutics designed to improve the emotional and cognitive disturbances associated with absence epilepsy.

    We report an investigation of P300 measures of information processing in patients with generalized epilepsy of the absence type and those with complex partial epilepsy. Studies have demonstrated that absence patients perform more poorly than complex partial patients on behavioral tests of sustained attention (the Continuous Performance Test, or CPT). Duncan [Duncan, C.C., 1988. Application of event-related brain potentials to the analysis of interictal attention in absence epilepsy. In: Myslobodsky, M.S., Mirsky, A.F. (Eds.), Elements of Petit Mal Epilepsy. Peter Lang, New York, pp. 341-364] reported that P300 was significantly reduced in a group of absence patients as compared with healthy controls. The present investigation was undertaken to compare the attention deficit in absence patients to that in complex partial seizure patients. Thus, ERPs were recorded while participants with absence seizure disorder, complex partial seizure disorder, and healthy controls performed auditory and visual versions of the CPT. A significant reduction in the amplitude of P300 on the visual CPT was observed in both groups of seizure patients as compared to controls. In contrast, P300 on the auditory CPT was reduced only in the group with absence seizures. These ERP data support and amplify previous behavioral findings of the impaired capacity of absence patients to mobilize and sustain attentional resources. Auditory sustained attention seems to be more affected by the pathophysiology of absence epilepsy than visual attention. Two possible factors may be involved: (a) There are separate visual and auditory attention systems in the brain, and the latter is more vulnerable than the former [Duncan, C.C., Kosmidis, M.H., Mirsky, A.F., 2005. Closed head injury-related information processing deficits: An event-related potential analysis. Int. J. Psychophysiol. 58, 133-157]; and (b) Auditory processing depends on intact mechanisms in the brainstem, which are dysfunctional in patients

    Metabolic disorders are discussed which are associated with the pathophysiological mechanisms of the origin of convulsions. Homeostasis impairment, e. g. hyponatremia, hypo- and hyperkalemia, hypocalcemia is mentioned, as well as vitamin deficiencies, such as pyridoxin deficiency, and the problem of phenylketonuria is discussed in connection with aminoacid disorders. Possible connections between aminoacid disorders and BNS, occurring in 8.1% of 1,688 children treated for epilepsy at the neurological department of the Brno Faculty Children's Hospital, are further discussed. Results of screening for amino-aciduria (according to Berry's method) were negative in 3000 healthy infants, whereas careful investigation resulted in pathologic aminoaciduria in 17 out of 20 children with BNS. Also results of hormonal treatment in children with this sort of convulsions are reported. It is concluded that early therapy, even though incapable of influencing neurological abnormities, suppresses convulsions and may lead to the disappearance of hypsarythmia from the EEG curve. A benign influence upon mental development was observed in a small group of children in whom therapy had been initiated very early. It is emphasized that this, by no means indifferent, type of therapy should only be performed in a well equipped and managed pediatric department.

    We previously demonstrated that heterozygous deletion of Gabra1, the mouse homolog of the human absence epilepsy gene that encodes the GABAA receptor (GABAAR) α1 subunit, causes absence seizures. We showed that cortex partially compensates for this deletion by increasing the cell surface expression of residual α1 subunit and by increasing α3 subunit expression. Absence seizures also involve two thalamic nuclei: the ventrobasal (VB) nucleus, which expresses only the α1 and α4 subtypes of GABAA...

    Full Text Available Objective: To optimize the use of phenobarbital and/or phenytoin as frontline drugs for treatment of childhood epilepsy. Design: Before-and -after study. Setting: Epilepsy clinic at paediatric OPD, Sassoon General Hospital, Pune. Materials and Methods: Epilepsy is a condition in which seizures are triggered recurrently from within the brain. For epidemiological classification purpose epilepsy is considered to be present when two or more unprovoked seizures occur at an interval greater than twenty four hours apart. Seizures were classified as generalized and partial seizures, with underlying etiology investigated with EEG, CT scan in majority of the patients. Follow - up rate, seizure - control and antiepileptic drugs used among 151 children enrolled as on 31 March 2005 were compared with 106 children with new onset epilepsy enrolled as on February 2006. Eight children with breakthrough convulsion after a seizure free period of five to eighteen months were followed up after injection vitamin D. Nineteen children with poor control of seizures receiving polytherapy with newer antiepileptic drugs were assessed with frontline antiepileptic medication of phenobarbital and/or phenytoin. Serum calcium, phosphorus, alkaline phosphatase were done in seventy two consecutive children with seizure disorder. Results: During post protocol period good seizure control was achieved in 84.8% as against 80.7% and use of phenobarbital and/or phenytoin increased to 65.11% from 22.87%. Of the 8 cases with breakthrough seizures seven remained seizure free after vitamin D administration and with no dose enhancement of AED medications of the nineteen. Children receiving polytherapy thirteen children could be successfully switched to phenobarbital and/or phenytoin.

    2016-04-01

    Cognitive impairment associated with childhood-onset epilepsy is an important consequence in the developing brain owing to its negative effects on neurodevelopmental and social outcomes. While the cause of cognitive impairment in epilepsy appears to be multifactorial, epilepsy-related factors such as type of epilepsy and underlying etiology, age at onset, frequency of seizures, duration of epilepsy, and its treatment are considered important. In recent studies, antecedent cognitive impairment before the first recognized seizure and microstructural and functional alteration of the brain at onset of epilepsy suggest the presence of a common neurobiological mechanism between epilepsy and cognitive comorbidity. However, the overall impact of cognitive comorbidity in children with epilepsy and the independent contribution of each of these factors to cognitive impairment have not been clearly delineated. This review article focuses on the significant contributors to cognitive impairment in children with epilepsy.

    Childhood epilepsies comprise a broad range of disorders which vary from benign to progressive and disabling. Accurate diagnosis of epilepsy type and determination of aetiology, when possible, are essential for appropriate treatment. The most common seizure type encountered in children is febrile seizures. These represent a benign condition which is not, in fact, epilepsy and usually does not require antiepileptic medication. When partial seizures occur in childhood, benign syndromes with spontaneous remission, such as rolandic epilepsy, must be distinguished from symptomatic epilepsies which may be refractory to medical management. Complex partial seizures in young children may appear different than in adults. The adverse effect profiles and dosing regimens of antiepileptic drugs in children are also different than in adults, and influence the choice of treatment. Epilepsy surgery should be considered for some children with intractible partial seizures. Generalized epilepsies also have a broader spectrum in children. The idiopathic generalized absence epilepsies are usually easy to control with medication. They range from childhood absence epilepsy which tends to remit in adolescence to juvenile myoclonic epilepsy which is a lifelong condition. In contrast, the seizures of West syndrome and Lennox-Gastaut syndrome are difficult to control, and treatment involves therapeutic modalities rarely used in adults such as ACTH and the ketogenic diet. Many childhood epilepsy syndromes have a familial predisposition, and the genetic bases for several disorders have been described.

Pregabalin as an add-on therapy has a postive effect on refractory seizures in adults. To the best of our knowledge, there is no research with this drug in childhood epilepsy. We use pregabalin in children with refractory seizures as an add-on therapy. The objective of this study is to evaluate the effects of pregabalin in the reduction of seizures for refractory epilepsy.Material & MethodsForty patients with refractory seizures who were referred to Mofid Children’s Hospital and Hazrat Masoumeh Hospital were selected. A questionnaire based on patient record forms, demographic data (age, gender,…, type of seizure, clinical signs, EEG record, imaging report, drugs that had been used, drugs currently being used, and the number of seizures before and after Pregabalin treatment was completed. We checked the number of seizures after one and four months.ResultsAfter one month, 26.8% of patients had more than a 50% reduction in seizures and 14.6% of these patients were seizure-free; 12.2% had a 25–50% reduction; and approximately 61% had less than a 25% reduction or no change in seizures.After the fourth month, 34.1% of patients had more than a 50% reduction in seizures and 24.4% of these patients were seizure-free. Additionally, 65.9% of patients had less than 50% reduction in seizures (9.8% between 25–50% and 56.1% less than 25% or without improvement.ConclusionWe recommend Pregabalin as an add-on therapy for refractory seizures (except for myoclonic seizures for children.ReferencesKwan P., Brodie MJ.

    The aim was to systematically review studies that have focused on symptoms of anxiety reported by parents of children (0-18 years) with epilepsy. PubMed was used to identify relevant studies. Selected studies were reviewed with respect to prevalence of above threshold scores and comparisons with controls on standardized measures of anxiety. Studies are also reported with respect to factors associated with parental anxiety, impact on child outcomes, and comparisons with studies that have included equivalent measures of symptoms of depression. Fifteen studies that met inclusion criteria were identified. None of the studies were population based. The percentage of parents scoring above cutoffs on standardized measures of anxiety was 9-58%. In comparison with parents of healthy controls, parents of children with epilepsy had higher mean scores in two of three studies where this was measured. Possible correlates of parental anxiety in childhood epilepsy that were considered varied widely across studies. Factors such as seizure frequency and use of antiepileptic drugs (AEDs) have been associated with parental anxiety in some but not all studies. With respect to child outcome, increased parental anxiety has been associated with lower quality of life and lower scores on adaptive behavior domains. Symptoms of anxiety are common among parents of children with epilepsy. There is a need for more systematic, representative studies to identify the prevalence of clinically significant anxiety and track the course of symptoms. Such studies will help to identify more clearly factors associated with parental anxiety and impact of symptoms on child and parent outcomes. Intervention studies are needed to evaluate approaches that target a reduction in symptoms and the potential impact on parental and child functioning. Furthermore, there is a need to evaluate the impact of antiepileptic therapies and interventions that focus on child neurobehavioral comorbidities on parental anxiety.

    Full Text Available Idiopathic childhood focal epilepsy with centrotemporal spikes, which is more known as rolandic epilepsy (RE, is age- and localization-related epilepsy with childhood onset, which is characterized mainly by short-lasting hemifacial and oropharyngeal seizures generally occurring when awakening or falling asleep, by the normal neurological status of patients, by specific electroencephalographic changes and complete arrest of seizures during therapy or when achieving puberty.RE is the most common epilepsy in childhood. Its prevalence is 21 per 100,000 healthy children. It is characterized by an onset that is clearly related to age. In 85 % of cases, RE occurs at 4–10 years of age with its peak at about 9 years. The clinical manifestations of this form of epilepsy are several types of seizures, such as oropharyngolaryngeal, hemifacial, faciobrachial, secondarily generalized convulsive, unilateral seizures with the possible development of short duration Todd’s paresis. Other types of seizures (absence, atonic, and myoclonic ones are uncharacteristic of RE. They may occur occasionally on aggravation resulting from the use of carbamazepine or oxcarbazepine or permanently on transformation into pseudo-Lennox syndrome. According to the definition, focal neurological symptoms and behavioral and intellectual disorders are absent in patients with RE. However, there have been recent observations suggesting that speech, cognitive, and behavioral disorders may occur (at the same time rarely in children with RE. Magnetic resonance imaging (MRI fails to reveal the abnormality in the vast majority of cases. The described MRI changes in nearly 10 % of the patients with RE are an incidental finding and irrelevant to the course of the disease. Valproate in small doses is a first-choice drug; if it is inefficient, levetiracetam, topiramate, or a combination of valproate and ethosuximide are administered.

    Brain cholesterol synthesis inhibition (CSI) at a young age in rats has been shown to be a faithful model of acquired absence epilepsy, a devastating condition for which few therapies or models exist. We employed the CSI model to study cellular mechanisms of acquired absence epilepsy in Long-Evans Hooded rats. Patch-clamp, whole-cell recordings were compared from neurons acutely dissociated from the nucleus reticularis of thalamus (nRt) treated and untreated with a cholesterol synthesis inhibitor, U18666A. In U18666A-treated animals, 91% of rats developed EEG spike-waves (SWs). Patchclamp results revealed that although there was no remarkable change in GABAA receptor affinity, both a loss of ability of benzodiazepines to enhance GABAA-receptor responses and an increase of Zn2+ inhibition of GABAA-receptor responses of nRt neurons occurred in Long-Evans Hooded rats previously administered U18666A. This change was specific, since no significant changes were found in neurons exposed to the GABA allosteric modulator, pentobarbital. Taken collectively, these findings provide evidence for abnormalities in benzodiazepine and Zn2+ modulation of GABAA receptors in the CSI model, and suggest that decreased gamma2 subunit expression may underlie important aspects of generation of thalamocortical SWs in atypical absence seizures. The present results are also consistent with recent findings that mutation of the gamma2 subunit of the GABAA receptor changes benzodiazepine modulation in families with generalized epilepsy syndromes.

    We previously demonstrated that heterozygous deletion of Gabra1, the mouse homolog of the human absence epilepsy gene that encodes the GABAA receptor (GABAAR) α1 subunit, causes absence seizures. We showed that cortex partially compensates for this deletion by increasing the cell surface expression of residual α1 subunit and by increasing α3 subunit expression. Absence seizures also involve two thalamic nuclei: the ventrobasal (VB) nucleus, which expresses only the α1 and α4 subtypes of GABAAR α subunits, and the reticular (nRT) nucleus, which expresses only the α3 subunit subtype. Here, we found that, unlike cortex, VB exhibited significantly reduced total and synaptic α1 subunit expression. In addition, heterozygous α1 subunit deletion substantially reduced miniature inhibitory postsynaptic current (mIPSC) peak amplitudes and frequency in VB. However, there was no change in the expression of the extrasynaptic α4 or δ subunits in VB and, unlike other models of absence epilepsy, no change in tonic GABAAR currents. Although heterozygous α1 subunit knockout increased α3 subunit expression in medial thalamic nuclei, it did not alter α3 subunit expression in nRT. However, it did enlarge the presynaptic vesicular inhibitory amino acid transporter puncta and lengthen the time constant of mIPSC decay in nRT. We conclude that increased tonic GABAA currents are not necessary for absence seizures. In addition, heterozygous loss of α1 subunit disinhibits VB by substantially reducing phasic GABAergic currents and surprisingly, it also increases nRT inhibition by prolonging phasic currents. The increased inhibition in nRT likely represents a partial compensation that helps reduce absence seizures. PMID:25447232

    The link between epilepsy and sleep is well established on many levels. The focus of the current review is on recent neuroimaging investigations into the alterations of consciousness that are observed during absence seizures and the descent into sleep. Functional neuroimaging provides simultaneous cortical and subcortical recording of activity throughout the brain, allowing a detailed definition and characterization of large-scale brain networks and the interactions between them. This has led to the identification of a set of regions which collectively form the consciousness system, which includes contributions from the default mode network (DMN), ascending arousal systems, and the thalamus. Electrophysiological and neuroimaging investigations have also clearly demonstrated the importance of thalamocortical and corticothalamic networks in the evolution of sleep and absence epilepsy, two phenomena in which the subject experiences an alteration to the conscious state and a disconnection from external input. However, the precise relationship between the consciousness system, thalamocortical networks, and consciousness itself remains to be clarified. One of the fundamental challenges is to understand how distributed brain networks coordinate their activity in order to maintain and implement complex behaviors such as consciousness and how modifications to this network activity lead to alterations in consciousness. By taking into account not only the level of activation of individual brain regions but also their connectivity within specific networks and the activity and connectivity of other relevant networks, a more specific quantification of brain states can be achieved. This, in turn, may provide a more fundamental understanding of the alterations to consciousness experienced in sleep and epilepsy.

    International Nuclear Information System (INIS)

    As surgical treatments for adult and pediatric forms of epilepsy have become more refined, methods for noninvasive localization of epileptogenic foci have become increasingly important. Detection of focal brain metabolic or flow abnormalities is now well recognized as an essential step in the presurgical evaluation of many patients with epilepsy. Positron emission tomography (PET) scanning is most beneficial when used in the context of the total clinical evaluation of patients, including scalp EEG, invasive EEG, neuropsychologic testing, etc. Metabolic PET studies also give insight into pathophysiologic mechanisms of epilepsy. The dynamic nature of the interictal hypometabolism observed with 18[F]FDG in some patients suggests that excitatory or inhibitory neurotransmitters and their receptors may be involved. An exciting current application of PET scanning is the use of tracers for neurotransmitter receptors in the study of epilepsy patients. Mu and non-mu opiate receptors have been extensively studied and are beginning to give new insights into this disorder. Increased labeling of mu receptors in temporal neocortex using 11C-carfentanil has been demonstrated and, in some patients, supplements the clinical localization information from 18[F]FDG studies. Increased mu opiate receptor number or affinity is thought to play a role in anticonvulsant mechanisms. Specificity of increased mu receptors is supported by the absence of significant changes in non-mu opiate receptors. Other brain receptors are also of interest for future studies, particularly those for excitatory neurotransmitters. Combined studies of flow, metabolism, and neuroreceptors may elucidate the factors responsible for initiation and termination of seizures, thus improving patient treatment.95 references

  9. The sleep-wakefulness cycle of Wistar rats with spontaneous absence-like epilepsy

    2015-07-01

    Full Text Available Possible interactions between the sleep-wakefulness cycle and a new kind of spontaneous epilepsy, expressed as absence-like seizures and spike-wave bursts in FMUSP rats, are evaluated. The electro-oscillograms of some cortical and subcortical regions of the brain were recorded, as well as head, rostrum/vibrissae and eye movements. Recordings were performed uninterruptedly during 24 hours. The seizures were mostly concentrated in the wakefulness state but they could occur in any other phase, including paradoxical sleep. After the seizure, the rats usually returned to the same phase that was interrupted, although they often returned to wakefulness. There was an intense fragmentation of the sleep-wakefulness cycle. The incidence of each cycle phase was significantly reduced, except SIII of synchronized sleep and paradoxical sleep, thus maintaining the overall duration and architecture of the sleep-wakefulness cycle. The fragmentation of the cycle seems to be due to an impairment of the very processes that generate sleep and wakefulness. Electrophysiological and behavioral profiles of the FMUSP rats recommend accurate and comprehensive study of the animal model owing to its resemblance to seizures in humans and also to discrepancies with existing genetic or experimental epilepsy models.

    Objective. Herbal medicine has been widely used to treat drug resistant epilepsy. Shihogyejitang (SGT) has been commonly used to treat epilepsy. We investigated the effect and safety of SGT in children with drug resistant epilepsy. Design. We reviewed medical records of 54 patients with epilepsy, who failed to respond to at least two antiepileptic drugs and have been treated with SGT between April 2006 and June 2014 at the Department of Pediatric Neurology, I-Tomato Hospital, Korea. Effect was measured by the response rate, seizure-free rate, and retention rate at six months. We also checked adverse events, change in antiepileptic drugs use, and the variables related to the outcome. Results. Intent-to-treat analysis showed that, after six months, 44.4% showed a >50% seizure reduction, 24.1% including seizure-free, respectively, and 53.7% remained on SGT. Two adverse events were reported, mild skin rash and fever. Focal seizure type presented significantly more positive responses when compared with other seizure types at six months (p = 0.0284, Fisher's exact test). Conclusion. SGT is an effective treatment with excellent tolerability for drug resistant epilepsy patients. Our data provide evidence that SGT may be used as alternative treatment option when antiepileptic drug does not work in epilepsy children. PMID:27047568

    In the first experiment, the relationship between the phase of the estrous cycle and the number of spontaneously occurring spike-wave discharges was investigated in WAG/Rij rats, a model for generalized absence epilepsy. The electroencephalogram (EEG) was continuously recorded for 96 h in eight rats chronically equipped with cortical EEG electrodes. A circadian pattern emerged for the number of spike-wave discharges: a nadir during the first hours of the light period, and an acrophase during the first hours of the dark period. This daily maximum was increased at proestrus day compared with the other days of the cycle, when the plasma level of progesterone is enhanced specifically at these hours of this day. This suggests that progesterone enhances spike-wave discharges. There was no difference in the first few hours of the light period in the number of spike-wave discharges between proestrus and the three other days, suggesting that estradiol has no effect on spike-wave discharges. In the second study, the effects of the systemic administration of progesterone and 17 beta-estradiol on spike-wave discharges and spontaneous behavior were investigated. It was shown that progesterone (20 and 30 mg/kg) but not estradiol (0.17-1.5 mg/kg) increased the number and total duration of spike-wave discharges. On the other hand, injection of RU 38486 (10 and 30 mg/kg), an antagonist of intracellular progesterone receptors, had no effect on spike-wave discharges and did not block the stimulatory effect of progesterone. The antagonist of 17 beta-estradiol tamoxifen (1 and 3 mg/kg) did not evoke alterations in the number or duration of spike-wave discharges. Our results indicate that progesterone aggravates spike-wave discharges, but is not mediated through intracellular receptors. Since progesterone is rapidly metabolized in the brain to the positive modulator of GABA(A) receptor allopregnanolone, which increases spike-wave discharges in WAG/Rij rats, it is possible that the

    van Luijtelaar, G; Zobeiri, M

    2014-01-01

    The WAG/Rij model is a well characterized and validated genetic animal epilepsy model in which the for absence epilepsy highly characteristic spike-wave discharges (SWDs) develop spontaneously. In this review we discuss first some older and many new studies, with an emphasis on pharmacological and neurochemical studies towards the role of GABA and glutamate and the ion channels involved in the pathological firing patterns. Next, new insights and highlights from the last 5-10 years of reaearch in WAG/Rij rats are discussed. First, early environmental factors modulate SWD characteristics and antiepileptogenesis is possible. Also new is that the classically assumed association between sleep spindles and SWDs seems no longer valid as an explanatory role for the occurrence of SWDs in the genetic rodent models. A role of cortical and thalamic glial cells has been revealed, indicating a putative role for inflammatory cytokines. Neurophysiologic and signal analytical studies in this and in another rodent model (GAERS) point towards a cortical site of origin, that SWDs do not have a sudden onset, and propose a more important role for the posterior thalamus than was previously assumed. Finally it is proposed that the reticular nucleus of the thalamus might be heterogeneous with respect to its role in propagation and maintenance of SWDs. The presence of a well-established cortical region in which SWDs are elicited allows for research towards new non-invasive treatment options, such as transcranial direct current stimulation (tDCS) and transcranial magnetic stimulation (TMS). The first results show the feasibility of this new approach.

  17. Altered Functional Connectivity within and between Brain Modules in Absence Epilepsy: A Resting-State Functional Magnetic Resonance Imaging Study

    Directory of Open Access Journals (Sweden)

    Cui-Ping Xu

    2013-01-01

    Full Text Available Functional connectivity has been correlated with a patient’s level of consciousness and has been found to be altered in several neuropsychiatric disorders. Absence epilepsy patients, who experience a loss of consciousness, are assumed to suffer from alterations in thalamocortical networks; however, previous studies have not explored the changes at a functional module level. We used resting-state functional magnetic resonance imaging to examine the alteration in functional connectivity that occurs in absence epilepsy patients. By parcellating the brain into 90 brain regions/nodes, we uncovered an altered functional connectivity within and between functional modules. Some brain regions had a greater number of altered connections and therefore behaved as key nodes in the changed network pattern; these regions included the superior frontal gyrus, the amygdala, and the putamen. In particular, the superior frontal gyrus demonstrated both an increased value of connections with other nodes of the frontal default mode network and a decreased value of connections with the limbic system. This divergence is positively correlated with epilepsy duration. These findings provide a new perspective and shed light on how functional connectivity and the balance of within/between module connections may contribute to both the state of consciousness and the development of absence epilepsy.

  19. Single-Photon Emission Computed Tomography (SPECT) in childhood epilepsy

    International Nuclear Information System (INIS)

    The success of epilepsy surgery is determined strongly by the precise location of the epileptogenic focus. The information from clinical electrophysiological data needs to be strengthened by functional neuroimaging techniques. Single photon emission computed tomography (SPECT) available locally has proved useful as a localising investigation. It evaluates the regional cerebral blood flow and the comparison between ictal and interictal blood flow on SPECT has proved to be a sensitive nuclear marker for the site of seizure onset. Many studies justify the utility of SPECT in localising lesions to possess greater precision than interictal scalp EEG or anatomic neuroimaging. SPECT is of definitive value in temporal lobe epilepsy. Its role in extratemporal lobe epilepsy is less clearly defined. It is useful in various other generalized and partial seizure disorders including epileptic syndromes and helps in differentiating pseudoseizures from true seizures. The need for newer radiopharmaceutical agents with specific neurochemical properties and longer shelf life are under investigation. Subtraction ictal SPECT co-registered to MRI is a promising new modality. (author)

    A great number of clinical observations show a relationship between epilepsy and depression. Idiopathic generalized epilepsy, including absence epilepsy, has a genetic basis. The review provides evidence that WAG/Rij rats can be regarded as a valid genetic animal model of absence epilepsy with comorbidity of depression. WAG/Rij rats, originally developed as an animal model of human absence epilepsy, share many EEG and behavioral characteristics resembling absence epilepsy in humans, including the similarity of action of various antiepileptic drugs. Behavioral studies indicate that WAG/Rij rats exhibit depression-like symptoms: decreased investigative activity in the open field test, increased immobility in the forced swimming test, and decreased sucrose consumption and preference (anhedonia). In addition, WAG/Rij rats adopt passive strategies in stressful situations, express some cognitive disturbances (reduced long-term memory), helplessness, and submissiveness, inability to make choice and overcome obstacles, which are typical for depressed patients. Elevated anxiety is not a characteristic (specific) feature of WAG/Rij rats; it is a characteristic for only a sub-strain of WAG/Rij rats susceptible to audiogenic seizures. Interestingly, WAG/Rij rats display a hyper-response to amphetamine similar to anhedonic depressed patients. WAG/Rij rats are sensitive only to chronic, but not acute, antidepressant treatments, suggesting that WAG/Rij rats fulfill a criterion of predictive validity for a putative animal model of depression. However, more and different antidepressant drugs still await evaluation. Depression-like behavioral symptoms in WAG/Rij rats are evident at baseline conditions, not exclusively after stress. Experiments with foot-shock stress do not point towards higher stress sensitivity at both behavioral and hormonal levels. However, freezing behavior (coping deficits) and blunted response of 5HT in the frontal cortex to uncontrollable sound stress

    Benign rolandic epilepsy (BRE), childhood idiopathic occipital epilepsy (CIOE), childhood absence epilepsy (CAE), and juvenile myoclonic epilepsy (JME) are some of the common epilepsy syndromes in the pediatric age group. Among the four, BRE is the most commonly encountered. BRE remits by age 16 years with many children requiring no treatment. Seizures in CAE also remit at the rate of approximately 80%; whereas, JME is considered a lifelong condition even with the use of antiepileptic drugs (AEDs). Neonates and infants may also present with seizures that are self-limited with no associated psychomotor disturbances. Benign familial neonatal convulsions caused by a channelopathy, and inherited in an autosomal dominant manner, have a favorable outcome with spontaneous resolution. Benign idiopathic neonatal seizures, also referred to as "fifth-day fits," are an example of another epilepsy syndrome in infants that carries a good prognosis. BRE, CIOE, benign familial neonatal convulsions, benign idiopathic neonatal seizures, and benign myoclonic epilepsy in infancy are characterized as "benign" idiopathic age-related epilepsies as they have favorable implications, no structural brain abnormality, are sensitive to AEDs, have a high remission rate, and have no associated psychomotor disturbances. However, sometimes selected patients may have associated comorbidities such as cognitive and language delay for which the term "benign" may not be appropriate.

    response were the number of anti-epileptic drugs (β = -0.27, P = 0.05) and sleep quality (β = 0.30, P = 0.03). In conclusion, we show that children with acute stress-sensitive seizures have a decreased cortisol response to stress. These results support our hypothesis that stress-sensitivity of seizures is associated with alterations of the stress response, thereby providing a first step in unravelling the mechanisms behind the seizure-precipitating effects of stress. Increased knowledge of the relation between stress and seizures in childhood epilepsy might benefit our understanding of the fundamental processes underlying epilepsy and ictogenesis in general, and provide valuable clues to direct the development of new therapeutic strategies for epilepsy.

    Full Text Available Absence epilepsy (AE is etiologically heterogeneous and has at times been associated with idiopathic dystonia.Based on the clinical observation that children with AE often exhibit, interictally, a disorder resembling writer's cramp but fully definable as dysgraphia, we tested the hypothesis that in this particular population dysgraphia would represent a subtle expression of dystonia.We ascertained the prevalence of dysgraphia in 82 children with AE (mean age 9.7 and average intelligence and compared them with 89 age-, gender- and class-matched healthy children (mean age 10.57 using tests for handwriting fluency and quality, based on which we divided patients and controls into four subgroups: AE/dysgraphia, AE without dysgraphia, controls with dysgraphia and healthy controls. We compared the blink reflex recovery cycle in children belonging to all four subgroups.We identified dysgraphia in 17/82 children with AE and in 7/89 controls (20.7 vs 7.8%; P = 0.016 with the former having a 3.4-times higher risk of dysgraphia regardless of age and gender (odd ratio: 3.49; 95% CI 1.2, 8.8%. The AE/dysgraphia subgroup performed worse than controls with dysgraphia in one test of handwriting fluency (P = 0.037 and in most trials testing handwriting quality (P< 0.02. In children with AE/dysgraphia the blink reflex showed no suppression at short interstimulus intervals, with a difference for each value emerging when comparing the study group with the three remaining subgroups (P<0.001.In children with AE, dysgraphia is highly prevalent and has a homogeneous, distinctive pathophysiological substrate consistent with idiopathic dystonia.

    Full Text Available A epilepsia é desordem crônica que ocorre principalmente na infância e adolescência. Tradicionalmente, o tratamento da epilepsia enfatiza aspectos neurológicos mais do que fatores psicológicos. A atenção voltada simplesmente para o controle das crises no contexto clínico pode não ser suficiente para entender a grande amplitude de problemas que afetam a qualidade de vida das crianças com epilepsia. Muitas das dificuldades psicossociais dos adultos com epilepsia desenvolvem-se a partir de complicações associadas ao início da doença. Crianças com epilepsia têm alta prevalência de problemas de comportamento e aprendizagem. Avaliar a qualidade de vida em crianças com epilepsia é importante, especialmente porque elas passam por períodos críticos de desenvolvimento, durante os quais são desenvolvidas habilidades cognitivas e sociais. A fim de instrumentalizar o profissional que atende crianças epilépticas, este estudo apresenta um inventário simplificado de qualidade de vida, no qual são abordados aspectos culturais, pessoais, sociais e relacionamento familiar e social. Esta investigação possibilita maior conhecimento sobre a criança e um melhor direcionamento nas condutas terapêuticas.Epilepsy is a chronic disorder in which onset occurs primarily during childhood and adolescence.

    Prognosis describes the trajectory and long-term outcome of a condition. Most studies indicate a better prognosis in idiopathic generalized epilepsy (IGE) in comparison with other epilepsy syndromes. Studies looking at the long-term outcome of different IGE syndromes are relatively scant. Childhood absence epilepsy appears to have a higher rate of remission compared to juvenile absence epilepsy. In absence epilepsies, development of myoclonus and generalized tonic-clonic seizures predicts lower likelihood of remission. Although most patients with juvenile myoclonic epilepsy (JME) achieve remission on antiepileptic drug therapy, remission without treatment. Data on the prognosis of other IGE syndromes are scarce. There are contradictory findings reported on the value of electroencephalography as a predictor of prognosis. Comparisons are made difficult by study heterogeneity, particularly in methodology and diagnostic criteria.

    Full Text Available Panayiotopoulos syndrome (PS is a relatively frequent and benign epileptic syndrome seen in children in the age group of 3-6 years and is characterised by predominantly autonomic symptoms and/or simple motor focal seizures followed or not by impairment of consciousness. Although multifocal spikes with high amplitude sharp-slow wave complexes at various locations can be present in the EEG, interictal electroencephalogram (EEG in children with this particular type of epilepsy characteristically shows occipital spikes. This syndrome has known to be a masquerader and can imitate gastroenteritis, encephalitis, syncope, migraine, sleep disorders or metabolic diseases. In the absence of thorough knowledge of types of benign epilepsy syndromes and their various clinical presentations, epilepsy such as PS can be easily missed. The peculiar aspects of this type of epilepsy in children should be known not only by paediatricians but also by general doctors because a correct diagnosis would avoid aggressive interventions and concerns on account of its benign outcome. In this case study, we report a case of PS in a 3 year old child.

    Deep brain stimulation (DBS) is a promising approach for epilepsy treatment, but the optimal targets and parameters of stimulation are yet to be investigated. Tuberomamillary nucleus (TMN) is involved in EEG desynchronization-one of the proposed mechanisms for DBS action. We studied whether TMN stimulation could interfere with epileptic spike-wave discharges (SWDs) in WAG/Rij rats with inherited absence epilepsy and whether such stimulation would affect sleep-wake cycle. EEG and video registration were used to determine SWD occurrence and stages of sleep and wake during three-hours recording sessions. Stimulation (100Hz) was applied in two modes: closed-loop (with previously determined interruption threshold intensity) or open-loop mode (with 50% or 70% threshold intensity). Closed-loop stimulation successfully interrupted SWDs but elevated their number by 148 ± 54% compared to baseline. It was accompanied by increase in number of episodes but not total duration of both active and passive wakefulness. Open-loop stimulation with amplitude 50% threshold did not change measured parameters, though 70% threshold stimulation reduced SWDs number by 40 ± 9%, significantly raised the amount of active wakefulness and decreased the amount of both slow-wave and rapid eye movement sleep. These results suggest that the TMN is unfavorable as a target for DBS as its stimulation may cause alterations in sleep-wake cycle. A careful choosing of parameters and control of sleep-wake activity is necessary when applying DBS in epilepsy.

    During 5 years, 104 patients with different types of idiopathic generalized epilepsy were treated with depakine and depakine-chrono in monotherapy and polytherapy schedule. Thirty-three patients had childhood absence epilepsy, 34--juvenile absence epilepsy, 33--juvenile myoclonic epilepsy and 3--generalized convulsive seizures in wake up periods. Mean medication dose was 1200 mg daily. Significant improvement of the patient's state was revealed in 50% of the cases, being most efficient in patients with juvenile myoclonic epilepsy (60.6%) and in children absence epilepsy (57.5%). Indices of remission formation and quality changed in the same direction--complete remissions were more frequent in juvenile absence epilepsy. Depakine is concluded to be an effective medication for the treatment of idiopathic generalized epilepsy.

    Mutations in inhibitory GABAA receptor subunit genes (GABRA1, GABRB3, GABRG2 and GABRD) have been associated with genetic epilepsy syndromes including childhood absence epilepsy (CAE), juvenile myoclonic epilepsy (JME), pure febrile seizures (FS), generalized epilepsy with febrile seizures plus (GEFS+), and Dravet syndrome (DS)/severe myoclonic epilepsy in infancy (SMEI). These mutations are found in both translated and untranslated gene regions and have been shown to affect the GABAA receptors by altering receptor function and/or by impairing receptor biogenesis by multiple mechanisms including reducing subunit mRNA transcription or stability, impairing subunit folding, stability, or oligomerization and by inhibiting receptor trafficking.

    The neuroanatomical substrates of absence seizures and convulsive seizures differ; absence seizures are generated in the cortico-thalamic loop, whereas the brain stem and limbic structures are involved in audiogenic convulsive seizures. In spite of this difference, the two seizure types share a major precipitating factor: emotional stress, although absence seizures are more likely to be provoked by stress than other types of epileptic seizures. This implies that mechanisms of stress vulnerabi...

    An Ala322Asp mutation in the GABRA1 gene was recently reported to be responsible for causing the autosomal dominant (AD) form of juvenile myoclonic epilepsy (JME) in a French-Canadian family. To study if JME families from India exhibiting the AD mode of inheritance carry the Ala322Asp mutation, we examined 35 unrelated JME-affected individuals from such families for the Ala322Asp mutation in GABRA1. Ala322Asp mutation was not observed in any of these JME-affected individuals, suggesting that this mutation is unlikely to be a predominant mutation involved in causation of epilepsy. To evaluate the possibility of other mutation(s) in and around GABRA1 that may predispose to JME, we compared the allele frequencies at two marker loci, D5S2118 and D5S422, flanking GABRA1, in probands and 100 matched population controls. One of the allele frequencies at D5S422 shows a significant difference between the cases and controls (2 = 11.44, d.f. = 1, $P = 0.0007$), suggesting genetic association between JME and genes located in the proximity of the DNA marker.

    Most studies about cognitive functions in children with benign childhood epilepsy with centrotemporal spikes (BCECTS) have been conducted with alphabetic writing background subjects, however deficits observed might therefore potentially differ in a Chinese language environment. This study was designed to evaluate the intelligence quotient (IQ) profiles, especially the language abilities, in Chinese children with BCECTS and to investigate whether there is a relationship between clinical factors and disorders of cognitive functions. There are selective cognitive deficits in Chinese children with BCECTS, although the Full Scale Intelligence Quotient is within the normal range. There was a correlation between spike wave index (SWI) and language deficits in children with BCECTS, but the deficits are not dependent on age of onset, disease course, seizure frequency, spike location or seizure type. It is important that children with typical BCECTS undergo regular clinical investigations about language performance in order to start necessary interventions as early as possible. PMID:22020258

The purpose of this study was to identify predictors of failure to respond to the initial antiepileptic drug (AED. Materials and Methods: A total of 42 children with BOEC were enrolled. Predictive factors were analyzed by survival methods. Results: Among the 42, 25 patients (59.5% were boys and 17 (40.5% were girls and the mean age at the seizure onset was 7.46 ± 2.65 years (4-14 years. Of the 42 patients, 34 (81.0% were treated relatively successfully with the first AED treatment, and 8 (19.0% were not responded initial AED treatment. There was no correlation between response to initial AED treatment and sex, consanguinity, epilepsy history of family, age of seizure onset, frequency of seizures, history of status epilepticus, duration of starting first treatment, findings on electroencephalogram. However, history of febrile seizure and type of BOEC were significantly associated with failure risk. Conclusions: Factors predicting failure to respond to the AED were history of febrile seizure and type of BOEC in children with BOEC.

    Epilepsy is a kind of common neurological diseases in the world. Over 50% of epilepsies have genetic basis. We define "idiopathic epilepsy" as a kind of epilepsy or epilepsy syndrome only with genetic factors, and idiopathic generalized epilepsies (IGEs) is a major type of idiopathic epilepsies. Susceptibility genes of epilepsies are mainly ion channel genes. Both gene mutation and copy number variation lead to epilepsies. Childhood absence epilepsy (CAE) is a crucial part of IGEs. Due to the consistency of CAE' s phenotype and results of EEG, studies related to CAE susceptibility genes tend to be easier to conduct. Through these studies about IGEs /CAE susceptibility genes, we can determine pathogenic model of epilepsy genetics, and find the way to diagnose accurately in molecular genetics, to identify types of epilepsies, to detect targets of antiepileptic drugs, and provide a basis for gene therapy.

    Genetic absence epilepsy rats from Strasbourg (GAERS) are a strain of Wistar rats in which all animals present spontaneous occurrence of spike and wave discharges (SWD) in the cortical electroencephalogram (EEG). In this paper, we present a method for the detection of SWD, based on the key observation that SWD are quasi-periodic signals. A spectral-comb based analysis method is used to extract the fundamental frequency and the percentage of energy explained by the harmonic spectral components is subsequently used as a detection parameter. It is shown that a maximum sensitivity and specificity of up to 96 per cent can be achieved. We also compared the performance of this method with the methods presented in the literature and conclude that the surplus value of the novel detection method lies in the higher specificity that can be obtained in the analysis of long-term EEG fragments, which are contaminated by artefacts and contain large portions of slow-wave sleep.

  3. Inherited cortical HCN1 channel loss amplifies dendritic calcium electrogenesis and burst firing in a rat absence epilepsy model.

    2007-01-15

    While idiopathic generalized epilepsies are thought to evolve from temporal highly synchronized oscillations between thalamic and cortical networks, their cellular basis remains poorly understood. Here we show in a genetic rat model of absence epilepsy (WAG/Rij) that a rapid decline in expression of hyperpolarization-activated cyclic-nucleotide gated (HCN1) channels (I(h)) precedes the onset of seizures, suggesting that the loss of HCN1 channel expression is inherited rather than acquired. Loss of HCN1 occurs primarily in the apical dendrites of layer 5 pyramidal neurons in the cortex, leading to a spatially uniform 2-fold reduction in dendritic HCN current throughout the entire somato-dendritic axis. Dual whole-cell recordings from the soma and apical dendrites demonstrate that loss of HCN1 increases somato-dendritic coupling and significantly reduces the frequency threshold for generation of dendritic Ca2+ spikes by backpropagating action potentials. As a result of increased dendritic Ca2+ electrogenesis a large population of WAG/Rij layer 5 neurons showed intrinsic high-frequency burst firing. Using morphologically realistic models of layer 5 pyramidal neurons from control Wistar and WAG/Rij animals we show that the experimentally observed loss of dendritic I(h) recruits dendritic Ca2+ channels to amplify action potential-triggered dendritic Ca2+ spikes and increase burst firing. Thus, loss of function of dendritic HCN1 channels in layer 5 pyramidal neurons provides a somato-dendritic mechanism for increasing the synchronization of cortical output, and is therefore likely to play an important role in the generation of absence seizures.

    Full Text Available Absence status epilepticus (ASE is a type of nonconvulsive status epilepticus in which continuous or recurrent generalized epileptiform discharges are associated with a varying grade of consciousness impairment. Absence status epilepticus may be obtained during progress of many epileptic syndromes, in several metabolic disturbances and related to use of several drugs. Absence status epilepticus is generally seen in childhood; rarely it can be seen in adulthood. In this paper, the case which has never diagnosed until now in spite of many absence seizures for years, applied for absence seizures to our clinic and diagnosed for juvenile absence epilepsy, has been discussed.

    Slow IPSPs, which are believed to be involved in generation of the wave of spike-wave epileptiform discharges, are mediated by the GABAB receptor. We therefore examined the effect of the GABAB antagonist, Ciba Geigy Product, CGP-35348, in the cholesterol synthesis inhibitor model of absence epilepsy in rat. Rats received Ayerst-9944 (AY-9944), from 6-45 mg i.p. in the first few weeks of life. By 2 months after AY-9944 administration these rats exhibited recurrent spike-waves and behavioral arrests. In 10 such animals CGP-35348 was administered intraperitoneally in doses of 0 (vehicle), 10, 25 or 100 mg/kg. EEG recordings were obtained via previously implanted bone screws. Technologists blinded to treatment group counted spike-waves over a 4 h period post-injection. The average number of spike-wave burst seconds per 4 h of recording for all dosages and times was 52.4 +/- 81.4 (mean +/- S.D.) s. Mean burst times (seconds) were vehicle = 93.5 +/- 106.5; 10 mg/kg = 69.9 +/- 79.7; 25 mg/kg = 30.8 +/- 46.9; 100 mg/kg = 15.2 +/- 54, a mean 84% reduction at 100 mg/kg (ANOVA regression significant at 0.0001). Spike-waves were suppressed for at least 4 h after injection of CGP-35348. These findings supplement similar findings in other absence models, and support a potential role for GABAB antagonists in treatment of absence seizures.

    2003-08-01

    Full Text Available Abstract Childhood epilepsy is one of the most important and prevalent neurological conditions in the developing years. Persons with childhood onset epilepsy are at a high risk for poor psychosocial outcomes, even without experiencing co-morbidities. The goal of management of children with epilepsy should be to enable the child and the family to lead a life as free as possible from the medical and psychosocial complications of epilepsy. This comprehensive care needs to go beyond simply trying to control seizures with minimal adverse drug reactions. Seizure frequency and severity is only one important outcome variable. Other factors such as social, psychological, behavioural, educational, and cultural dimensions of their lives affect children with epilepsy, their families and their close social networks. A number of epilepsy-specific health-related quality of life (HRQL scales for children have been developed with the aim to include and measure accurately the impact and burden of epilepsy. Their target populations, details of the origin of the items, and psychometric properties vary significantly. Their strengths and weaknesses will be identified more clearly through their continued use in the clinical setting and in research studies. Only a few studies to date have utilized these or generic HRQL measures to assess the HRQL of specific populations with epilepsy. Future research needs to develop theory driven models of HRQL and identify measurable factors that have important correlations with outcomes. Since biomedical variables like seizure frequency and severity have only moderate correlations with HRQL, other independent factors including the child's resilience, co-morbid conditions, parental well-being, family factors and societal/cultural variables may play a major role. We also need to learn what encompasses comprehensive patient care, define the goals of management and evaluate the impact of different interventions. Future studies need to

METHOD: This study included patients with criteria of AS followed up at the Epilepsy Clinic. A dual, cross-sectional cohort study was carried out between 2005 and 2008. Patients receiving care in the Epilepsy Program of the HUCFF-UFRJ, who had been investigated by video-EEG and who presented clinical and EEG criteria for absence seizures, typical or atypical, according to the criteria defined by the ILAE, were included in the study, independent of age onset, the review of clinical history, age onset, family history, epilepsy onset and evolution, seizures phenomenology, antiepileptic drugs response and neuroimaging studies were used to classify the patients among the different epileptic syndrome associated to absence seizures. RESULTS: Typical absences were more frequent (71.4% than atypical absences. Cases of juvenile absence epilepsy were the most frequent (19% in this series, followed by childhood absence epilepsy (14.4% and juvenile myoclonic epilepsy (4.8%. In 14 patients (66.67%, diagnosis was modified from focal epilepsy to primary generalized epilepsy. Clinical and EEG diagnosis of absence epilepsy resulted in a dramatic improvement in the control of seizures following modification of diagnosis and indication of an appropriate antiepileptic drug. CONCLUSION: Our results show that typical AS are more frequent than atypical. AS was successfully defined in 10 patients following

    is without a doubt one of the most ancient and enigmatic conditions in the history of medicine, as it was already described in remote times. From the ancestral obscure understanding of epilepsy to the present, there have been important scientific advances in the knowledge of its diagnosis and treatment. The management of a child with epilepsy requires following a protocol that includes a detailed clinical and laboratory evaluation. All chronic diseases, and also epilepsy, are felt as a double aggression: 1 Internal, related to the changes that the disease causes, and 2 external, related to the tests, medications, excessive protection, and all the rules and prohibitions that are applied. The doctor (pediatrician, pediatric neurologist or epileptologist, when initiating a relationship with the child with epilepsy, is going to propose "a new code", often hard to accept. He is going to intervene far away from the crisis, or soon after it happened, in an environment characterized by significant anguish for the family. There is no question that the disease is difficult for the child, as it is also for the parents, who become responsible for a different type of care, are preoccupied daily about their son taking the medication regularly, and suffer awaiting for another crisis to happen. Epilepsy, more than other conditions, creates a high level of restlessness because of the spectacular, dramatic nature of its presentation and for the ancestral myths still attributed to it. For all these reasons, the diagnosis of epilepsy is frequently accompanied by three relevant reactions in the family: anxiety, guilt and aggressiveness. The intervention of the doctor in the treatment of childhood epilepsy must be "global". With mystic devotion, the doctor must embrace the true Hippocratic concept of patient care.

    Full Text Available This study intended to investigate the clinical and electroencephalographic benign occipital epilepsy of childhood (BOEC characteristics in a population sample of patients from two tertiary Brazilian hospitals. We analyzed retrospectively 4912 electroencephalograms (EEGs records, and the included patients were submitted to a new clinical and EEG evaluation. Were included 12 (0.92% patients; 4 (33.3% with criteria for early BOEC; 6 (50% for late form and 2 (16.7% with superimposed early and late onset forms. After new investigation, 2 (16.7% had normal EEG; 4 (33.3% had paroxysms over the occipital region; 3 (25% over the temporal posterior regions and 3 (25% over the posterior regions. Sharp waves were the predominant change, occurring in 8 (66.6%; spike and slow wave complexes in 1 (8.3% and sharp and slow wave complexes in 1 (8.3%. Vomiting, headache and visual hallucinations were the most common ictal manifestations, presented in 100% of patients with superimposed forms. Vomiting were absent in the late form and headache was present in all forms of BOEC.

    Sleep spindles are known to appear spontaneously in the thalamocortical neuronal network of the brain during slow-wave sleep; pathological processes in the thalamocortical network may be the reason of the absence epilepsy. The aim of the present work is to study developed changes in the time-frequency structure of sleep spindles during the progressive development of the absence epilepsy in WAG/Rij rats. EEG recordings were made at age 7 and 9 months. Automatic recognition and subsequent analysis of sleep spindles on the EEG were performed using the continuous wavelet transform. The duration of epileptic discharges and the total duration of epileptic activity were found to increase with age, while the duration of sleep spindles, conversely, decreased. In terms of the mean frequency, sleep spindles could be divided into three classes: `slow' (mean frequency 9.3Hz), `medium' (11.4Hz), and `fast' (13.5Hz). Slow and medium (transitional) spindles in five-month-old animals showed increased frequency from the beginning to the end of the spindle. The more intense the epilepsy is, the shorter are the durations of spindles of all types. The mean frequencies of `medium' and `fast' spindles were higher in rats with more intense signs of epilepsy. Overall, high epileptic activity in WAG/Rij rats was linked with significant changes in spindles of the transitional type, with less marked changes in the two traditionally identified types of spindle, slow and fast.

    Absence epilepsy is more prevalent in females, but reasons for this gender asymmetry are unknown. We reported previously that perinatal treatment of Long-Evans Hooded rats with the cholesterol synthesis inhibitor (CSI) AY9944 causes a life-long increase in EEG spike-wave discharges (SWDs), correlated with decreased expression of GABA(A) receptor subunit gamma2 protein levels in thalamic reticular and ventrobasal nuclei (SS thalamus) [Li, H., Kraus, A., Wu, J., Huguenard, J.R., Fisher, R.S., 2006. Selective changes in thalamic and cortical GABA(A) receptor subunits in a model of acquired absence epilepsy in the rat. Neuropharmacology 51, 121-128]. In this study, we explored time course and gender different effects of perinatal AY9944 treatment on expression of GABA(A) receptor alpha1 and gamma2 subunits in SS thalamus and SS cortex. Perinatal AY9944 treatment-induced decreases in GABA(A) gamma2 receptor subunits in rat SS thalamus and increases in SS cortex are gender and age specific. The findings suggest a mechanism for the higher prevalence of absence epilepsy in female patients.

    The International League Against Epilepsy (ILAE) Subcommittee for Pediatric Neuroimaging examined the usefulness of, and indications for, neuroimaging in the evaluation of children with newly diagnosed epilepsy. The retrospective and prospective published series with n {>=} 30 utilizing computed tomography (CT) and magnetic resonance imaging (MRI) (1.5 T) that evaluated children with new-onset seizure(s) were reviewed. Nearly 50% of individual imaging studies in children with localization-related new-onset seizure(s) were reported to be abnormal; 15-20% of imaging studies provided useful information on etiology or and seizure focus, and 2-4% provided information that potentially altered immediate medical management. A significant imaging abnormality in the absence of a history of a localization-related seizure, abnormal neurologic examination, or focal electro-encephalography (EEG) is rare. Imaging studies in childhood absence epilepsy, juvenile absence epilepsy, juvenile myoclonic epilepsy, and benign childhood epilepsy with centro-temporal spikes (BECTS) do not identify significant structural abnormalities. Imaging provides important contributions to establishing etiology, providing prognostic information, and directing treatment in children with recently diagnosed epilepsy. Imaging is recommended when localization-related epilepsy is known or suspected, when the epilepsy classification is in doubt, or when an epilepsy syndrome with remote symptomatic cause is suspected. When available, MRI is preferred to CT because of its superior resolution, versatility, and lack of radiation. (authors)

    For several years we have been following patients with intractable, childhood-onset idiopathic generalised epilepsies with > or = 3 Hz spike-wave discharges. Our need to find explanations for their intractability was the starting point for this study. We were interested in identifying characteristics, which would predict intractability; evaluating how these patients were treated and whether polytherapy was useful. We identified patients with > or = 3 Hz spike-wave discharges by reviewing EEG reports recorded between 1983 and 1992. Data were collected from medical records and through personal interviews. We identified 82 patients with tentative idiopathic generalised epilepsy. Eleven were excluded. Thirty-eight patients had childhood absence epilepsy, 18 had juvenile absence epilepsy, 13 had juvenile myoclonic epilepsy and two had eyelid myoclonia with absences: 89.5, 78, 38 and 0% of the patients in each group, respectively, had been seizure free for more than 2 years. Twenty percent of the patients had intractable seizures. All intractable patients with juvenile absence epilepsy had rhythmic, random eyelid blinking and generalised tonic-clonic seizures. A history of more than ten generalised tonic-clonic seizures was associated with intractability in juvenile myoclonic patients. Monotherapy with ethosuximide or valproate resulted in seizure control in 65% of patients. Seventeen patients (24%) were treated with polytherapy, six achieved remission. These six patients had childhood absence epilepsy and juvenile absence epilepsy. Positive outcome was found in childhood absence epilepsy and juvenile absence epilepsy. Intractable seizures were more frequent among patients with juvenile myoclonic epilepsy. None of them benefited from polytherapy with conventional anti-epileptic drugs.

  19. The timing of pediatric epilepsy syndromes: what are the developmental triggers?

    2013-11-01

    Pediatric epilepsy is characterized by multiple epilepsy syndromes with specific developmental triggers. They initiate spontaneously at critical periods of development and can just as spontaneously remit. Accompanying neurocognitive disabilities are often specific to the epileptic syndrome. Infantile or epileptic spasms have a very specific developmental window in the first year of life. Preceding the epilepsy, developmental arrest is common. The neurologic pathways underlying the development of spasms have been identified through PET scans as developmental abnormalities of serotonergic and GABAergic neurotransmitter systems in the brain stem and basal ganglia. Childhood absence epilepsy (CAE) and benign centrotemporal epilepsy syndrome (BECTS) are both known genetic epilepsy syndromes; they have a discrete onset in childhood with remission by puberty. In CAE, disturbances of specific calcium channels at key developmental stages lead to aberrant disruption of thalamocortical synchrony. Similarly, a complex interplay between brain development, maturation, and susceptibility genes underlies the seizures and the neurocognitive deficits of BECTS.

    To define the risk factors for postencephalitic epilepsy (PE) and drug-resistant epilepsy (DRE) in childhood following infectious and autoimmune encephalitis, we included 147 acute encephalitis patients with a median follow-up of 7.3 years (range 2-15.8 years). PE was defined as the use of antiepileptic drugs (AEDs) for ≥24 months, and DRE was defined as the persistence of seizures despite ≥2 appropriate AEDs at final follow-up. PE and DRE were diagnosed in 31 (21%) and 15 (10%) of patients, respectively. The features during acute encephalitis predictive of DRE (presented as odds ratio [OR] with confidence intervals [CIs]) were status epilepticus (OR 10.8, CI 3.4-34.3), visual disturbance (6.4, 1.4-29.9), focal seizures (6.2, 1.9-20.6), magnetic resonance imaging (MRI) hippocampal/amygdala involvement (5.0, 1.7-15.4), intensive care admission (4.7, 1.4-15.4), use of >3 AEDs (4.5, 1.2-16.1), MRI gadolinium enhancement (4.1, 1.2-14.2), any seizure (3.9, 1.1-14.4), and electroencephalography (EEG) epileptiform discharges (3.9, 1.3-12.0). On multivariable regression analysis, only status epilepticus remained predictive of DRE in all models. DRE was common in herpes simplex virus (3/9, 33%) and unknown (8/40, 20%) encephalitis, but absent in acute disseminated encephalomyelitis (ADEM) (0/32, 0%), enterovirus (0/18), and anti-N-methyl-d-aspartate receptor-NMDAR encephalitis (0/9). We have identified risk factors for DRE and demonstrated "high-risk," and "low-risk" etiologies.

    Full Text Available Idiopathic occipital epilepsy is a rare epileptic syndrome. Its incidence in a Novosibirsk cohort of patients with idiopathic focal epilepsy is 0.9%. Objective: to present a clinical description of new cases of Gastaut syndrome, the types of its course, and treatment options in these patients. Patients and methods. The study covers 17 cases of Gastaut type idiopathic occipital epilepsy in 13 women and 4 men aged 11–53 years. Results. Among 17 cases we present 4 family cases with the disease. Three generations in 2 families were observed to have epilepsy, including Gastaut syndrome concurrent with childhood absence epilepsy. The adolescent onset of the disease was seen in most cases. Its main symptoms were focal visual seizures (100%, focal sensory seizures (58.9%, cephalalgia (47.1%, speech disorders (41.2%, and secondarily generalized convulsive seizures (35.3%. According to the frequency of seizures, the investigators identified 5 types of the course: single focal seizures, rare focal seizures with or without convulsions, frequent focal seizures with or without convulsions. The identity of the course of epilepsy was found in familial cases. 76.5% of the patients had a good quality of life: 41.2% of them were untreated while 35.3% were treated; no seizures were noted.

    Full Text Available Occipital intermittent rhythmic delta activity (OIRDA is considered good prognostic factor in typical absences (TA. We report electroclinical evolution in 14 patients with TA and OIRDA, which performed video-EEG. Seven patients were female; 9 had childhood absence epilepsy and the others did not present electroclinical characteristics for syndromic classification according to ILAE's classification (1989. Pyknolepsy was referred to in 13; TA was the only seizure type in 13; one had generalized tonic-clonic seizures (GTCS and three had myoclonic jerks during TA. VPA monotherapy controlled seizures in 11, diVPA and ESM, in one each. After seizure control EEG normalized in 10 while in three, spike-wave complexes (SWC persisted, accompanied by OIRDA in one. Finally in another, seizures were not controlled and SWC and OIRDA persisted. In conclusion, we observed in this series of TA and OIRDA with onset before 10 years, pyknolepsy as common finding and few GTCS. VPA controlled seizures in most cases and EEG normalized in 76.92%. We suggest that OIRDA could be considered good prognostic factor in TA associated with SWC and of epileptiform nature leading to appropriate investigation.Atividade occipital delta rítmica intermitente (AODRI é considerada fator de bom prognóstico em crises de ausência típica (AT.

    Children and adolescents with epilepsy are known to demonstrate executive function deficits. Despite prior work that has shown that cognitive estimation tasks are sensitive to executive dysfunction in children, such tasks have not been studied in children with epilepsy. This is particularly important given the fact that executive tasks have heretofore shown poor ecological validity, and it has been speculated that estimation tasks may show stronger ecological validity than other executive tests. One hundred and thirteen clinically referred children and adolescents with epilepsy were included. The Biber Cognitive Estimations Test was sensitive to cognitive dysfunction, with about half showing impairments on this task in comparison to age-matched normative data; the most frequently impaired subscales were quantity estimation and time estimation. Moreover, the Biber Cognitive Estimation Test showed moderate correlations with not only overall intellectual functions and academic achievement but also other commonly administered tests of executive functions, including digit span, Trailmaking, and the Tower of London but not with the contingency naming test. Cognitive estimations were also modestly correlated with age of epilepsy onset but not other epilepsy-severity variables such as number of antiepilepsy drugs (AEDs) or seizure frequency. Unfortunately, the hypothesis that the Biber Cognitive Estimation Test would show strong ecological validity was not supported, as it showed weak relations with parent-reported executive function deficits. The significance and limitations of this investigation are discussed.

    Full Text Available Vitamin D (VD is implicated in multiple aspects of human physiology and vitamin D receptor (VDR polymorphisms are associated with a variety of neuropsychiatric disorders. Although VD deficiency is highly prevalent in epilepsy patients and converging evidence indicates a role for VD in the development of epilepsy, no data is available on the possible relationship between epilepsy and genetic variations of VDR. In this study, 150 controls and 82 patients with temporal lobe epilepsy (TLE were genotyped for five common VDR polymorphisms (Cdx-2, FokI, BsmI, ApaI and TaqI by the polymerase chain reaction-ligase detection reaction method. Our results revealed that the frequency of FokI AC genotype was significantly higher in the control group than in the patients (p = 0.003, OR = 0.39, 95% CI = 0.21–0.73, whereas the AA genotype of ApaI SNP was more frequent in patients than in controls (p = 0.018, OR = 2.92, 95% CI = 1.2–7.1. However, no statistically significant association was found between Cdx-2, BsmI and TaqI polymorphisms and epilepsy. Additionally, in haplotype analysis, we found the haplotype GAT (BsmI/ApaI/TaqI conferred significantly increased risk for developing TLE (p = 0.039, OR = 1.62, 95% CI = 1.02–2.56. As far as we know, these results firstly underline the importance of VDR polymorphisms for the genetic susceptibility to epilepsy.

    2013-06-01

    Full Text Available This study evaluated the sequential motor manual actions in children with benign focal epilepsy of childhood with centrotemporal spikes (BECTS and compares the results with matched control group, through the application of Luria's fist-edge-palm test. The children with BECTS underwent interictal single photon emission computed tomography (SPECT and School Performance Test (SPT. Significant difference occurred between the study and control groups for manual motor action through three equal and three different movements. Children with lower school performance had higher error rate in the imitation of hand gestures. Another factor significantly associated with the failure was the abnormality in SPECT. Children with BECTS showed abnormalities in the test that evaluated manual motor programming/planning. This study may suggest that the functional changes related to epileptiform activity in rolandic region interfere with the executive function in children with BECTS.

  8. Community structure analysis of transcriptional networks reveals distinct molecular pathways for early- and late-onset temporal lobe epilepsy with childhood febrile seizures.

    Directory of Open Access Journals (Sweden)

    Carlos Alberto Moreira-Filho

    Full Text Available Age at epilepsy onset has a broad impact on brain plasticity and epilepsy pathomechanisms. Prolonged febrile seizures in early childhood (FS constitute an initial precipitating insult (IPI commonly associated with mesial temporal lobe epilepsy (MTLE. FS-MTLE patients may have early disease onset, i.e. just after the IPI, in early childhood, or late-onset, ranging from mid-adolescence to early adult life. The mechanisms governing early (E or late (L disease onset are largely unknown. In order to unveil the molecular pathways underlying E and L subtypes of FS-MTLE we investigated global gene expression in hippocampal CA3 explants of FS-MTLE patients submitted to hippocampectomy. Gene coexpression networks (GCNs were obtained for the E and L patient groups. A network-based approach for GCN analysis was employed allowing: i the visualization and analysis of differentially expressed (DE and complete (CO - all valid GO annotated transcripts - GCNs for the E and L groups; ii the study of interactions between all the system's constituents based on community detection and coarse-grained community structure methods. We found that the E-DE communities with strongest connection weights harbor highly connected genes mainly related to neural excitability and febrile seizures, whereas in L-DE communities these genes are not only involved in network excitability but also playing roles in other epilepsy-related processes. Inversely, in E-CO the strongly connected communities are related to compensatory pathways (seizure inhibition, neuronal survival and responses to stress conditions while in L-CO these communities harbor several genes related to pro-epileptic effects, seizure-related mechanisms and vulnerability to epilepsy. These results fit the concept, based on fMRI and behavioral studies, that early onset epilepsies, although impacting more severely the hippocampus, are associated to compensatory mechanisms, while in late MTLE development the brain is less

    Recent research has revealed that benign childhood epilepsy with centrotemporal spikes (BECTS) causes deficient performance in various neuropsychological areas, without arriving at a definition of a uniform profile. The purpose of this study was to examine intelligence and certain language functions in 24 children with an active centrotemporal focus, comparing them with a group of 16 controls matched for age and schooling. Test results were correlated with several EEG characteristics, including focal versus multifocal presentation of interictal epileptiform activity, lateralization, spike maximum on midtemporal or extratemporal electrodes, and rate of interictal activity when awake and during non-REM sleep. Our study demonstrated that children with BECTS have mild language defects, revealed by tests measuring phonemic fluency, verbal re-elaboration of semantic knowledge, and lexical comprehension. Interictal EEG discharges demonstrated that a high rate of occurrence while awake, multifocal location, and temporal prominence seem to impair the efficiency of some of the neuropsychological functions investigated. However, because the last EEG was obtained within the last 2 months (on average) before the assessment, and because BECTS is a form of epilepsy with signs of cortical hyperexcitability that vary over time in terms of rate, side, and location, the pattern of neuropsychological deficiencies could have changed (at least to some degree) by the time of the test, with respect to the EEG variables considered.

    Down syndrome (DS) is a common congenital anomaly, and children with DS have a substantially higher risk of leukemia. Although understanding of genetic and epigenetic changes of childhood leukemia has improved, the causes of childhood leukemia and the potential role of environmental exposures in leukemogenesis remain largely unknown. Although many epidemiologic studies have examined a variety of environmental exposures, ionizing radiation remains the only generally accepted environmental risk factor for childhood leukemia. Among suspected risk factors, infections, exposure to pesticides, and extremely low frequency magnetic fields are notable. While there are well-defined differences between leukemia in children with and without DS, studies of risk factors for leukemia among DS children are generally consistent with trends seen among non-DS (NDS) children. We provide background on DS epidemiology and review the similarities and differences in biological and epidemiologic features of leukemia in children with and without DS. We propose that both acute lymphoblastic and acute myeloblastic leukemia among DS children can serve as an informative model for development of childhood leukemia. Further, the high rates of leukemia among DS children make it possible to study this disease using a cohort approach, a powerful method that is unfeasible in the general population due to the rarity of childhood leukemia.

    Full Text Available The article describes the phenomenon of dual pathology – a combination of structural changes in the brain and benign epileptiform discharge of childhood on electroencephalogram. The uniqueness lies in the observation that the child, since birth suffering from spastic form of cerebral palsy and severe epilepsy, demonstrated the development of Stevens–Johnson syndrome due to intolerance of one of the antiepileptic drugs. Therapeutic approaches to overcome a whole range of violations are discussed in the article.

  14. Mutant GABA(A) receptor subunits in genetic (idiopathic) epilepsy.

    The γ-aminobutyric acid receptor type A (GABAA receptor) is a ligand-gated chloride channel that mediates major inhibitory functions in the central nervous system. GABAA receptors function mainly as pentamers containing α, β, and either γ or δ subunits. A number of antiepileptic drugs have agonistic effects on GABAA receptors. Hence, dysfunctions of GABAA receptors have been postulated to play important roles in the etiology of epilepsy. In fact, mutations or genetic variations of the genes encoding the α1, α6, β2, β3, γ2, or δ subunits (GABRA1, GABRA6, GABRB2, GABRB3, GABRG2, and GABRD, respectively) have been associated with human epilepsy, both with and without febrile seizures. Epilepsy resulting from mutations is commonly one of following, genetic (idiopathic) generalized epilepsy (e.g., juvenile myoclonic epilepsy), childhood absence epilepsy, genetic epilepsy with febrile seizures, or Dravet syndrome. Recently, mutations of GABRA1, GABRB2, and GABRB3 were associated with infantile spasms and Lennox-Gastaut syndrome. These mutations compromise hyperpolarization through GABAA receptors, which is believed to cause seizures. Interestingly, most of the insufficiencies are not caused by receptor gating abnormalities, but by complex mechanisms, including endoplasmic reticulum (ER)-associated degradation, nonsense-mediated mRNA decay, intracellular trafficking defects, and ER stress. Thus, GABAA receptor subunit mutations are now thought to participate in the pathomechanisms of epilepsy, and an improved understanding of these mutations should facilitate our understanding of epilepsy and the development of new therapies.

    Mutations in NPRL3, one of three genes that encode proteins of the mTORC1-regulating GATOR1 complex, have recently been reported to cause cortical dysplasia with focal epilepsy. We have now analyzed a multiplex epilepsy family by whole exome sequencing and identified a frameshift mutation (NM_001077350.2; c.1522delG; p.E508Rfs*46) within exon 13 of NPRL3. This truncating mutation causes an epilepsy phenotype characterized by early childhood onset of mainly nocturnal frontal lobe epilepsy. The penetrance in our family was low (three affected out of six mutation carriers), compared to families with either ion channel- or DEPDC5-associated familial nocturnal frontal lobe epilepsy. The absence of apparent structural brain abnormalities suggests that mutations in NPRL3 are not necessarily associated with focal cortical dysplasia but might be able to cause epilepsy by different, yet unknown pathomechanisms.

    Epilepsy is the most important neurological problem in developing countries, with a total of 50 million people worldwide having the condition. 33 million of these cases are children in developing countries, of whom 90% are untreated. To determine the number of children with active epilepsy in a given developing country community, previous studies have either ascertained information directly from key informants in the community or through more broad-based two-stage surveys. Findings are reported from a study conducted in 46 villages of district 24 Parganas South, a rural district south of Calcutta, comparing the two approaches' sensitivity, efficacy, and costs. Village leaders, health workers, and students were interviewed as key informants, while house-to-house surveys were conducted in 15,000 households. The survey was 4 times as sensitive as the key informant approach, although the approaches had similar positive predictive values. The survey had an absolute sensitivity of 59%. Case identification by key informants strongly predicted successful treatment outcomes. The cost of finding 1 case was US$11 and US$14, and of finding one successful treatment outcome US$35 and US$67 for informants and survey, respectively. The use of key informants was essential to attaining longer-term program objectives. PMID:9758124

    SQSTM1 (sequestosome 1; also known as p62) encodes a multidomain scaffolding protein involved in various key cellular processes, including the removal of damaged mitochondria by its function as a selective autophagy receptor. Heterozygous variants in SQSTM1 have been associated with Paget disease of the bone and might contribute to neurodegeneration in amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). Using exome sequencing, we identified three different biallelic loss-of-function variants in SQSTM1 in nine affected individuals from four families with a childhood- or adolescence-onset neurodegenerative disorder characterized by gait abnormalities, ataxia, dysarthria, dystonia, vertical gaze palsy, and cognitive decline. We confirmed absence of the SQSTM1/p62 protein in affected individuals' fibroblasts and found evidence of a defect in the early response to mitochondrial depolarization and autophagosome formation. Our findings expand the SQSTM1-associated phenotypic spectrum and lend further support to the concept of disturbed selective autophagy pathways in neurodegenerative diseases. PMID:27545679

    2014-01-01

    Full Text Available Acute lymphoblastic leukemia (ALL is a malignant disorder that originates from one single hematopoietic precursor committed to B- or T-cell lineage. Ordinarily, these cells express CCR5 chemokine receptor, which directs the immune response to a cellular pattern and is involved in cancer pathobiology. The genetic rs333 polymorphism of CCR5 (Δ32, results in a diminished receptor expression, thus leading to impaired cell trafficking. The objective of the present study was to investigate the effect of CCR5 chemokine receptor rs333 polymorphism in the pathogenesis of ALL. The genotype distribution was studied in 79 patients and compared with 80 control subjects, in a childhood population of Southern Brazil. Genotyping was performed using DNA samples amplified by polymerase chain reaction with sequence-specific primers (PCR-SSP. The homozygous (Δ32/Δ32 deletion was not observed in any subject involved in the study. Heterozygous genotype was not associated with ALL risk (OR 0.7%; 95% CI 0.21–2.32; P>0.05, nor recurrence status of ALL (OR 0.86; 95% CI 0.13–5.48; P>0.05. This work demonstrated, for the first time, no significant differences in the frequency of the CCR5/Δ32 genotype between ALL and control groups, indicating no effect of this genetic variant on the ALL susceptibility and recurrence risk.

    Clinical conditions of long-term cure in childhood-onset epilepsy, defined as sustained remission off antiepileptic drug (AED) treatment, are not well known. To address that clinically important question, we determined clinical factors predictive of long-term seizure cure in a population-based cohort of 133 patients followed up since their first seizure before the age of 16 years. At the end of the 45-year follow-up (mean=39.8, median=44, range=11-47), 81 (61%) of the 133 patients had entered at least 5-year remission off AEDs, meeting our definition of cure. The 81 patients were seizure-free off AEDs for a mean of 34.4 (median=38, range=6-46) years and 59 (73%) of the 81 patients following the first standard medication until the end of follow-up (mean=36.5, median=39, range=14-46 years). Four independent factors were found to be associated with cure compared with having seizures while on AEDs: seizure frequency less than weekly during the first 12 months of AED treatment (p=0.002), pretreatment seizure frequency less than weekly (p=0.002), higher IQ (>70; p=0.021), and idiopathic or cryptogenic vs. symptomatic etiology (p=0.042). Patients with seizure frequency of less than once a week during early treatment and idiopathic etiology had a ninefold chance to of being cured since the onset of the first adequate antiepileptic therapy until the end of follow-up compared with patients who a symptomatic etiology had at least weekly seizures while on AEDs (RR=8.7, 95% CI=2.0-37.0; pepilepsy.

However, there is a group of severe epilepsy that has many characteristics common to SMEI except for myoclonic seizures. We reported this group of epilepsy as intractable childhood epilepsy with GTC (ICEGTC) [Watanabe, M., Fujiwara, T., Yagi, K., Seino, M., Higashi, T., 1989b.

Long-term course of childhood epilepsy with intractable grand mal seizures. Jpn. J. Psychiatr. Neurol. 46, 297-302]. Recently, mutations of the neuronal voltage-gated sodium channel alphasubunit type 1 gene (SCN1A) have been found in SMEI [Claes, L., Del-Favero, J., Ceulemans, B., Lagae, L., Van Broeckhoven, C., De Jonghe, P., 2001, De novo mutations in the sodium-channel gene SCN1A cause severe myoclonic epilepsy of infancy. Am. J. Hum. Genet. 68, 327-1332]. Mutations in SCN1A are found in both SMEI and ICEGTC at high rates of 70-81%. The loci of the mutations seen in ICEGTC are quite similar to those found in SMEI, suggesting a genotypic continuity between these entities. The clinical spectrum of epilepsies harboring SCN1A

    Recent developments in research on cognitive abilities in benign rolandic epilepsy of childhood with centrotemporal spikes have led to interest in the following domains: language, memory, executive, motor, and visual-constructive functions. As previous studies have investigated the cognitive development of mainly school-aged children, this study focuses on preschool and elementary school children. Twenty-five children affected by benign rolandic epilepsy/rolandic discharges and 25 healthy children matched for age and sex were enrolled in this retrospective study. The mean IQ scores were 94.76 for children with epilepsy and 99.3 for control children. For the children with benign rolandic epilepsy, cognitive testing revealed increased verbal and nonverbal deficits with respect to articulation (P=0.002), auditory memory (P=0.003), visual memory (P=0.016), language comprehension (P=0.009), and visual-constructive performance (P=0.033), as compared with the children in the control group. In our sample, the results showed an association between rolandic epilepsy and language and memory deficits. As cognitive development in preschool children is progressive and dynamic, larger prospective follow-up studies, with assessments at different time points, will facilitate understanding of the cognitive profiles of children with rolandic epilepsy.

    Idiopathic generalised epilepsy (IGE) is subdivided into syndromes based on clinical and EEG features. PURPOSE: The aim of this study was to characterise all cases of IGE with supportive EEG abnormalities in terms of gender differences, seizure types reported, IGE syndromes, family history of epilepsy and EEG findings. We also calculated the limited duration prevalence of IGE in our cohort. METHODS: Data on abnormal EEGs were collected retrospectively from two EEG databases at two tertiary referral centres for neurology. Clinical information was obtained from EEG request forms, standardised EEG questionnaires and medical notes of patients. RESULTS: two hundred twenty-three patients met our inclusion criteria, 89 (39.9%) male and 134 (60.1%) females. Tonic clonic seizures were the most common seizure type reported, 162 (72.65%) having a generalised tonic clonic seizure (GTCS) at some time. IGE with GTCS only (EGTCSA) was the most common syndrome in our cohort being present in 94 patients (34 male, 60 female), with 42 (15 male, 27 female) patients diagnosed with Juvenile myoclonic epilepsy (JME), 23 (9 male, 14 female) with Juvenile absence epilepsy (JAE) and 20 (9 male, 11 female) with childhood absence epilepsy (CAE). EEG studies in all patients showed generalised epileptiform activity. CONCLUSIONS: More women than men were diagnosed with generalised epilepsy. Tonic clonic seizures were the most common seizure type reported. EGTCSA was the most frequent syndrome seen. Gender differences were evident for JAE and JME as previously reported and for EGTCSA, which was not reported to date, and reached statistical significance for EGTCA and JME.

    1991-01-01

    The concept of 'awakening epilepsy' (introduced by Janz, 1953) occupies a crucial position for the comprehension of primary generalized epilepsy. The associated electroencephalographic manifestations are discussed and the role of abnormal (paroxysmal) arousal responses ('dyshormia') is stressed. The origin of these bilateral-synchronous discharges appears to be located below the frontal midline scalp region in mesial portions of the supplementary motor region. 'Awakening epilepsy' is also interesting from the viewpoint of sleep research. There is also an important age factor; these seizures (mostly grand mal and classical petit mal absences) are most common in older children, adolescents and young adults. The general management of these patients has to take into account the patient's special vulnerability after a night of poor sleep.

    Seizures can give rise to enduring changes that reflect alterations in gene-expression patterns, intracellular and intercellular signaling, and ultimately network alterations that are a hallmark of epilepsy. A growing body of literature suggests that long-term changes in gene transcription associated with epilepsy are mediated via modulation of chromatin structure. One transcription factor in particular, repressor element 1-silencing transcription factor (REST), has received a lot of attention due to the possibility that it may control fundamental transcription patterns that drive circuit excitability, seizures, and epilepsy. REST represses a suite of genes in the nervous system by utilizing nuclear protein complexes that were originally identified as mediators of epigenetic inheritance. Epigenetics has traditionally referred to mechanisms that allow a heritable change in gene expression in the absence of DNA mutation. However a more contemporaneous definition acknowledges that many of the mechanisms used to perpetuate epigenetic traits in dividing cells are utilized by neurons to control activity-dependent gene expression. This review surveys what is currently understood about the role of epigenetic mechanisms in epilepsy. We discuss how REST controls gene expression to affect circuit excitability and neurogenesis in epilepsy. We also discuss how the repressor methyl-CpG-binding protein 2 (MeCP2) and activator cyclic AMP response element binding protein (CREB) regulate neuronal activity and are themselves controlled by activity. Finally we highlight possible future directions in the field of epigenetics and epilepsy.

Results There were 7 boys and 5 girls in 12 patients. The age of onset was from 3 to 9 years old. Two cases were dizygotic twins. The atypical symptoms included atypical absence of 10 cases, negative myoclonic seizure of 8 cases, speech expression disorders and oral-pharynx apraxia of 4 cases. The electroencephalography (EEG) of all 12 patients showed abundance of spike and waves (SW) in rolandic areas during wake-up and sleep. The SW index was 50%-85% during slow sleep in all patients.Conclusions The variants of BECT are often associated with EEG deterioration. Understanding the clinical featuress and EEG characteristics can help the diagnosis of BECT variants.%目的 探讨儿童良性癫痫伴中央颞区棘波(BECT)变异型的临床特征.方法 回顾性分析2007年1月至2014年1月收治的12例BECT变异型患儿的临床资料.结果 12例患儿中男7例、女5例,其中2例为双卵龙凤胎,起病年龄为3~9岁.病程中出现不典型失神10例,负性肌阵挛8例,言语障碍和口咽部失用4例.视频脑电图监测均显示清醒及睡眠期Rolandic区棘慢波大量发放,慢波睡眠期指数达50%~85%.结论 BECT变异型均伴有明显的脑电图恶化,认识其临床和脑电图变化的特点及规律,可提高对BECT变异型的诊断.

    International Nuclear Information System (INIS)

    Objective: To evaluate the diagnostic value of SPECT rCBF imaging in localization of childhood epileptic foci. Methods: rCBF imaging was performed in 74 epileptic patients not in seizure and 10 epileptic patients right in seizure. EEG was performed in 84, MRI in 67 of the subjects mentioned above. All the results of three modalities were compared with each other. Results: The highest positive rate (82.14%) was found in SPECT rCBF imaging, the positive rate in EEG or MRI was 71.43 or 47.76%. The epileptic foci localized by EEG (60 abnormalities) and by MRI (32 abnormalities) were 70.59% or 58.82% in concordance with those by SPECT, respectively. Conclusions: SPECT rCBF imaging is a sensitive and effective method for epileptic foci localization. It may have some advantages over EEG and MRI in detecting and localizing epileptic foci. However, abnormal SPECT areas may cover some abnormalities which do not belong to epileptic category. A combination of these three methods (SPECT, EEG and MRI) will improve the positive rate and accuracy for localizing

    We report two monochorionic twins that progressively developed, between ages 5 and 10, a combination of episodic neurological disorders including paroxysmal exercise-induced dyskinesia, migraine without or with aura, absence seizures and writer's cramp. CSF/serum glucose ratio was moderately decreased in both patients. Mutational analysis of SLC2A1 gene identified a de novo heterozygous missense mutation in exon 4. This novel mutation has been previously showed to disrupt glucose transport in vitro. Both patients showed immediate and near-complete response to ketogenic diet. This clinical observation suggests that a high index of suspicion for GLUT1 deficiency syndrome is warranted in evaluating patients with multiple neurological paroxysmal events.

    2011-09-01

    Ancient philosophers and theologians believed that altered consciousness freed the mind to prophesy the future, equating sleep with seizures. Only recently has the bidirectional influences of epilepsy and sleep upon one another received more substantive analysis. This article reviews the complex and increasingly recognized interrelationships between sleep and epilepsy. NREM sleep differentially activates interictal epileptiform discharges during slow wave (N3) sleep, while ictal seizure events occur more frequently during light NREM stages N1 and N2. The most commonly encountered types of sleep-related epilepsies (those with preferential occurrence during sleep or following arousal) include frontal and temporal lobe partial epilepsies in adults, and benign epilepsy of childhood with centrotemporal spikes (benign rolandic epilepsy) and juvenile myoclonic epilepsy in children and adolescents. Comorbid sleep disorders are frequent in patients with epilepsy, particularly obstructive sleep apnea in refractory epilepsy patients which may aggravate seizure burden, while treatment with nasal continuous positive airway pressure often improves seizure frequency. Distinguishing nocturnal events such as NREM parasomnias (confusional arousals, sleep walking, and night terrors), REM parasomnias including REM sleep behavior disorder, and nocturnal seizures if frequently difficult and benefits from careful history taking and video-EEG-polysomnography in selected cases. Differentiating nocturnal seizures from primary sleep disorders is essential for determining appropriate therapy, and recognizing co-existent sleep disorders in patients with epilepsy may improve their seizure burden and quality of life.

  3. Musicogenic epilepsy.

    Science.gov (United States)

    Stern, John

    2015-01-01

    Musicogenic epilepsy, which is a form of reflex epilepsy, is characterized by the triggering of epileptic seizures by specific music experiences. Individuals with musicogenic epilepsy differ in the music trigger, but may have similar seizures. Typically, these seizures are focal dyscognitive and have a temporal-lobe origin with a limbic system distribution. As such, the music trigger is likely related to either an emotional or memory aspect of music perception. Investigations into musicogenic epilepsy may lead to a better understanding of seizure propagation within the brain and of neurologic aspects of the music experience. Successful treatment of medication-resistant musicogenic epilepsy has been achieved with anterior temporal-lobe resection. PMID:25726285

    2012-10-01

    Full Text Available A range of medical and neurologic disorders occurs more frequently in people with epilepsy than in the general population and constitutes somatic comorbidity. Common examples include migraine, depression, schizophrenia, attention-deficit hyperactivity disorder (ADHD, sleep disorder, cognitive damage, developmental abnormality and so on. There are more interesting clinical features in some special types of patients with benign epilepsy of childhood with centrotemporal spikes (BECT, temporal epilepsy and mitochondrial encephalomyopathy. The association between epilepsy and other conditions can be due to a variety of interacting genetic, biologic structural, functional, pharmacological and environmental factors. Co-existence of other disorders in a person with epilepsy can complicate diagnosis, induce adverse prognostic implications and attenuate health?related quality of life. Therefore, recognition and management of comorbidity of epilepsy may facilitate the treatment of epilepsy. In this article, we review recent pathophysiologic and clinical studies to elucidate the etiology, mechanisms, clinical characteristics, differential diagnosis and treatment of common comorbidity of epilepsy.

    Despite the fact that epilepsy is the third most common chronic brain disorder, relatively little is known about the processes leading to the generation of seizures. Accumulating data support an autoimmune basis in patients with antiepileptic drug-resistant seizures. Besides, recent studies show that epilepsy and autoimmune disease frequently co-occur. Autoimmune epilepsy is increasingly recognized in the spectrum of neurological disorders characterized by detection of neural autoantibodies in serum or spinal fluid and responsiveness to immunotherapy. An autoimmune cause is suspected based on frequent or medically intractable seizures and the presence of at least one neural antibody, inflammatory changes indicated in serum or spinal fluid or on MRI, or a personal or family history of autoimmunity. It is essential that an autoimmune etiology be considered in the initial differential diagnosis of new onset epilepsy, because early immunotherapy assures an optimal outcome for the patient.

  10. Dietary Therapies for Epilepsy

    Directory of Open Access Journals (Sweden)

    Eric H Kossoff

    2013-02-01

    Full Text Available Since their introduction in 1921, high-fat, low-carbohydrate "ketogenic" diets have been used worldwide for refractory childhood epilepsy. Approximately half of the children have at least half their seizures reduced, including 15% who are seizure free. The mechanisms of action of dietary therapies are under active investigation and appear to involve mitochondria. Once perceived as a last resort, modifications to initiation and maintenance, as well as the widespread use of pre-made ketogenic formulas have allowed dietary treatment to be used earlier in the course of epilepsy. For infantile spasms (West syndrome specifically, the ketogenic diet is successful about 50% of the time as a first-line treatment. New "alternative" diets such as the modified Atkins diet were created in 2003 and can be started more easily and are less restrictive. They may have particular value for countries in Asia. Side effects include constipation, dyslipidemia, growth slowing, acidosis, and kidney stones. Additionally, neurologists are studying ketogenic diets for conditions other than epilepsy, including Alzheimer's disease, autism, and brain tumors.

    For children with pharmacoresistant epilepsy, the ketogenic diet is an established treatment option worldwide. However, for adults, this treatment is less frequently offered, and its efficacy less well-documented. The aim of this study was to examine efficacy and tolerability of such a diet as an adjuvant therapy to antiepileptic drugs for adult patients with pharmacoresistant generalized epilepsy. Thirteen patients (12 women) aged 16-57 years were included prospectively. They were treated with a modified Atkins diet for 12 weeks. Nine of the 13 participants had juvenile myoclonic epilepsy (JME), two had childhood absence epilepsy, one had Jeavons syndrome, and one had generalized epilepsy of unknown type. Six participants, all with JME, completed the 12-week study period. Among these six, four had >50% seizure reduction. Their seizure severity, using the revised Liverpool Seizure Severity Scale, was reduced by 1, 5, 57.5, and 70 points, respectively (scale: 1-100 points). In three of these four responders, quality of life, assessed by QOLIE-89, increased more than 20 points (scale: 0-100 points). Mean reduction of body weight after 12 weeks on diet was 6.5 (range: 4.3-8.1) kg. Lack of motivation, poor compliance, and seizure aggravation were the main reasons for premature termination of the diet. Apart from one patient who developed gallstones when ending the treatment after 10 months, no adverse effects were noted. In conclusion, using a modified Atkins diet for 12 weeks led to a clinically relevant reduction of seizure frequency in four of thirteen adult patients with pharmacoresistant generalized epilepsy. All responders were diagnosed with JME. In three of the four, the benefits of diet were so considerable that they chose to continue the treatment.

Their clinical and EEG observations were analyzed. Results: Majority of the patients had onset of seizures <20 years of age (n = 178; 62%. Thirty one patients (10.8% had family history of epilepsy. Nearly half of them (49.9% had <5 years of duration of seizures. The type of IGEs included Juvenile myoclonic epilepsy (JME: 115 (40.1%; IGE with generalized tonic-clonic seizures (GTCS only: 102 (39.02%; childhood absence epilepsy (CAE: 35 (12.2%; GTCS on awakening: 15 (5.2%; Juvenile absence epilepsy (JAE: 11 (3.8%; and unclassified seizures: 9 (3.1%. The triggering factors noted in 45% were sleep deprivation (20%, non-compliance and stress in 5% each. The EEG (n = 280 showed epileptiform discharges in about 50% of patients. Epileptiform discharges during activation was observed in 40/249 patients (16.1%: Hyperventilation in 32 (12.8% and photic stimulation in 19 (7.6%. The seizures were well controlled with anti-epileptic drugs (AEDs in 232 (80.8% patients and among them, 225 (78.4% patients were on monotherapy. Valproate (n = 131 was the most frequently prescribed as monotherapy. Conclusions: This is one of the largest cohort of patients with IGE. This study reiterates the importance of segregating IGE syndrome and such analysis will aid to the current understanding and management.

    Hesdorffer, Dale C; Trimble, Michael

    2016-04-01

    Associations between epilepsy and musical or poetic composition have received little attention. We reviewed the literature on links between poetic and musical skills and epilepsy, limiting this to the Western canon. While several composers were said to have had epilepsy, John Hughes concluded that none of the major classical composers thought to have had epilepsy actually had it. The only composer with epilepsy that we could find was the contemporary composer, Hikari Oe, who has autism and developed epilepsy at age 15years. In his childhood years, his mother found that he had an ability to identify bird sound and keys of songs and began teaching him piano. Hikari is able to compose in his head when his seizures are not severe, but when his seizures worsen, his creativity is lost. Music critics have commented on the simplicity of his musical composition and its monotonous sound. Our failure to find evidence of musical composers with epilepsy finds parallels with poetry where there are virtually no established poets with epilepsy. Those with seizures include Lord George Byron in the setting of terminal illness, Algernon Swinburne who had alcohol-related seizures, Charles Lloyd who had seizures and psychosis, Edward Lear who had childhood onset seizures, and Vachel Lindsay. The possibility that Emily Dickinson had epilepsy is also discussed. It has not been possible to identify great talents with epilepsy who excel in poetic or musical composition. There are few published poets with epilepsy and no great composers. Why is this? Similarities between music and poetry include meter, tone, stress, rhythm, and form, and much poetry is sung with music. It is likely that great musical and poetic compositions demand a greater degree of concentration and memory than is possible in epilepsy, resulting in problems retaining a musical and mathematical structure over time.

  1. Studies on homocarnosine in cerebrospinal fluid in infancy and childhood. Part II. Homocarnosine levels in cerebrospinal fluid from children with epilepsy, febrile convulsion or meningitis.

    Takahashi, H

    1981-01-01

    To clarify the pathophysiological role of homocarnosine in the cerebrospinal fluid (CSF) in children, homocarnosine levels in CSF were determined in patients with epilepsy (32 cases), febrile convulsion (5 cases) and meningitis (42 cases) with a high speed amino acid autoanalyzer (Hitachi Co.). Mean homocarnosine levels in CSF of controlled epileptic children, uncontrolled epileptic children and febrile convulsion cases were 0.61 +/- 0.25 mumol/dl, 1.03 +/- 0.37 mumol/dl and 1.09 +/- 0.04 mumol/dl, respectively. High homocarnosine levels in CSF of children with uncontrolled epilepsy or febrile convulsion may indicate the reduced turnover rate from homocarnosine to GABA. In patients with meningitis, the unconscious states were accompanied by significantly lower homocarnosine levels in CSF (0.39 +/- 0.20 mumol/dl) than those in the patients with clear conscious states (0.9 +/- 0.31 mumol/dl, however, in patients with clear conscious states homocarnosine in CSF were almost the same as those of normal children (0.89 +/- 0.23 mumol/dl). These data suggest that homocarnosine in CSF might be related to the convulsive tendency and consciousness. PMID:7283086

  2. Epilepsy in patients with Angelman syndrome

    Directory of Open Access Journals (Sweden)

    2010-04-01

    Full Text Available Abstract Angelman syndrome (AS is a neuro-behavioural, genetically determined condition, characterized by ataxic jerky movements, happy sociable disposition and unprovoked bouts of laughter in association with seizures, learning disabilities and language impairment. Most of the cases are hardly diagnosed during infancy as jerky movements, the cardinal sign, appear later in childhood. AS is caused by a variety of genetic mechanisms involving the 15q 11-13 chromosome. About 70% of cases are due to a "de novo" interstitial deletion in the long arm region, arising on the maternally inherited chromosome. The diagnosis is confirmed by methylation test or by mutation analysis of UBE3A gene. The deletion phenotype is generally linked to a more severe clinical picture in that 95% of patients manifest more severe seizures, severe mental and motor retardation, dysmorphic features and microcephaly. The pathogenesis of epilepsy in AS is still not fully understood. The presence in the commonly deleted region of a cluster of genes coding for 3 subunits of the GABAa receptor complex has lead to the hypothesis that GABA neurotransmission is involved. Epilepsy, often severe and hard to control, is present in 85% of patients within the first three years of life, although less than 25% develop seizures during the first year. It was observed that febrile seizures often precede the diagnosis. Most frequent types are atypical absences, generalized tonic-clonic, atonic or myoclonic seizures, with multiple seizure types occurring in 50% of deleted patients. There is still some doubt about the association with West syndrome. The EEG abnormalities are not themselves pathognomonic of AS and both background activity and epileptic discharges vary even in the same patient with time. Nevertheless, the existence of some suggestive patterns should facilitate the early diagnosis allowing the correct genetic counselling for the family. Some drugs seems to act better than others

    In childhood chronic illness, family communication can impact the child's and parents' psychosocial well-being. However, little is known about family communication in the context of epilepsy in childhood. The aim of this systematic review was to identify the existing evidence available on communication strategies adopted by families living with childhood epilepsy, including; the facilitators, barriers and challenges experienced by families when choosing to communicate, or not, about epilepsy; and the consequences of this communication. Papers published in the English language prior to March 2015 were identified following a search of six electronic databases: PubMed, MEDLINE, Web of Science, PsycINFO, CINAHL, and Scopus. Studies were included if they involved a sample of parents of children with epilepsy or children/young people with epilepsy (0-18years of age) and used qualitative, quantitative, or mixed methods. Following a comprehensive search and screening process, 26 studies were identified as eligible for inclusion in the review. No studies identified specific communication strategies adopted by families living with childhood epilepsy. Some studies found that talking about epilepsy with family members had positive consequences (e.g., communication as an effective coping strategy), with no negative consequences reported in any of the studies. The main barrier to communication for parents was an unwillingness to use the word "epilepsy" because of the perceived negative social connotations associated with the health condition. For children with epilepsy, barriers were as follows: parental desire to keep epilepsy a secret, parents' tendency to deny that the child had epilepsy, parental overprotection, and parents' tendency to impose greater restrictions on the child with epilepsy than on siblings without epilepsy. Future research investigating the communication strategies of families living with epilepsy is needed in order to create effective communication

    Typical childhood absence seizures consist of brief impairments of consaousness with characteristic bilaterally synchronous 3 Hz generalized spike-wave discharges (GSWD) on electroencephalography (EEG).Simultanoeus EEG-FMRI allows us observing the epileptic activation from haemodynamic and electrophysiological aspects. In present study, three patients with typical childhood absence seizures were studied using EEG-FMRI with 3 Hz epileptic wave power spectrum analysis. Significant activation was found in the bilateral thalamus, while the significant deactivation was found to be widely distributed within the bilateral parietal lobe, posteriar cingulate cortex, angular gyrus, and middle temporal lobe etc. The findings suggest that the thalamus may be the origin of epileptic activation, and the widely cortical functional inhibition may underlie the neuron-pathophysiological manchnism of impairments of consciousness in typical childhood absence seizures.%儿童失神癫痫是一类常见的原发全面性癫痫,表现为无抽搐性的阵发性意识丧失,以及3 Hz左右的头皮脑电全面慢波发放.应用同步记录头皮脑电与功能磁共振(simultaneous eleetroencephalography-functional magnetic resonance imaging,EEG-fMRI)技术,可以同时从血氧代谢和脑电生理角度对癫痫活动的空间特征进行观察.本研究采用EEG-fMRI技术对3例儿童失神癫痫进行研究,针对特征性的3 Hz失神癫痫波进行功率谱相关设计,发现双侧丘脑呈现出显著的激活信号,而双侧顶下小叶、后扣带回、前扣带回、角回、颞中回等默认网络区域呈现出显著的负激活.结果提示丘脑可能是失神性癫痫活动的起源区,而广泛的皮层功能抑制则可能是失神性癫痫意识丧失的神经病理生理基础.

    The present study assessed the long-term (i.e., 24months) efficacy of the ketogenic diet (KD) as an add-on therapy in children with refractory epilepsy, with focus on seizure frequency, seizure severity, and tolerability. Most patients were treated with the MCT-diet. At one and two years, 33% and 23%, respectively, of the 48 included patients were still on the KD. After three months, one year, and two years of treatment, 16.7% of the patients were responders. The highest responder rate (i.e., 22.9%) was seen at six and nine months of treatment. Of the fifteen patients with seizure clusters during baseline, 60% were responders after three months when looking at cluster reduction and most of them were not responders for the total seizure frequency. From three months of treatment onwards, most of the patients had a relevant decrease in seizure severity which was mainly related to the most severe seizure type. Gastrointestinal dysfunction was often reported, especially in the first six weeks of treatment. Growth deceleration was present in 30% of the patients, and weight reduction in 15%. Improved arousal was mentioned in 30% of patients. No patients developed ECG abnormalities or kidney stones. Increase in lipid profile was rare. The KD is an effective therapy for children with therapy-resistant epilepsy. Effectiveness is reflected in the reduction of seizure frequency as well as in the reduction of seizure severity. After 6months of treatment, it is obvious which patients are responders and tolerate the treatment well. Most of these patients will continue to benefit from the KD for a longer time. Long-term use of the diet was well tolerated. PMID:26301622

    2011-01-01

    Full Text Available Introduction. Juvenile myoclonic epilepsy is an idiopathic, hereditary form of epilepsy. Although juvenile myoclonic epilepsy is a well defined clinical syndrome, attempts at diagnosing it commonly fail. Etiopathogenesis. The exact cause of juvenile myoclonic epilepsy remains unknown. Clinical, morphological and metabolic data suggest a preferential role for frontal regions in this syndrome. Several major genes for juvenile myoclonic epilepsy have been identified, but these genes account for only a small proportions of juvenile myoclonic epilepsy cases, suggesting multifactorial or complex inheritance in most. Clinical Manifestations. Juvenile myoclonic epilepsy is characterized by the triad of myoclonic jerks on awakening (all patients, generalized tonic-clonic seizures (>90% of patients and typical absences (about one third of patients. Seizures have an age-related onset, circadian distribution and are frequently precipitated by sleep deprivation, fatigue and alcohol intake. Intelligence is normal. Diagnosis. Juvenile myoclonic epilepsy diagnosis is based upon clinical criteria and typical electroencephalographic findings (generalized pattern of spikes and/or polyspikes and waves. All other tests are normal. Treatment and Prognosis. Both medical treatment and counselling are important in the management of juvenile myoclonic epilepsy. Mono-therapy with valproate is the preferred treatment. Some of the newer antiepileptic drugs have been suggested as possible alternatives. Juvenile myoclonic epilepsy has a good prognosis. Lifelong treatment is usually considered necessary in vast majority of patients due to the increased risk of relapse if treatment is discontinued. Conclusion. Juvenile myoclonic epilepsy is a common, although under-diagnosed epileptic syndrome. The clinician should study the occurrence of myoclonic jerks and should consider atypical presentations.

    Impairments in executive skills broadly span across multiple childhood epilepsy syndromes and can adversely affect quality of life. Bilingualism has been previously shown to correlate with enhanced executive functioning in healthy individuals. This study sought to determine whether the bilingual advantage in executive functioning exists in the context of pediatric epilepsy. We retrospectively analyzed neuropsychological data in 52 children with epilepsy and compared executive function scores in monolingual versus bilingual children with epilepsy while controlling for socioeconomic status and ethnicity. Bilingual children performed significantly better on the Working Memory Index than did monolingual children. There were no significant differences on the remaining executive function variables. The bilingual advantage appears to persist for working memory in children with epilepsy. These findings suggest that bilingualism is potentially a protective variable in the face of epilepsy-related working memory dysfunction.

    In the recent years, several neurological syndromes related to defects of the glucose transporter type 1 (Glut1) have been descried. They include the glucose transporter deficiency syndrome (Glut1-DS) as the most severe form, the paroxysmal exertion-induced dyskinesia (PED), a form of spastic paraparesis (CSE) as well as the childhood (CAE) and the early-onset absence epilepsy (EOAE). Glut1, encoded by the gene SLC2A1, is the most relevant glucose transporter in the brain. All Glut1 syndromes respond well to a ketogenic diet (KD) and most of the patients show a rapid seizure control. Ketogenic Diet developed to an established treatment for other forms of pharmaco-resistant epilepsies. Since we were interested in the question if those patients might have an underlying Glut1 defect, we sequenced SLC2A1 in a cohort of 28 patients with different forms of pharmaco-resistant epilepsies responding well to a KD. Unfortunately, we could not detect any mutations in SLC2A1. The exact action mechanisms of KD in pharmaco-resistant epilepsy are not well understood, but bypassing the Glut1 transporter seems not to play an important role. PMID:26088884

  15. Computed tomography of late-onset epilepsy

    International Nuclear Information System (INIS)

    Epilepsy can be divided into idiopathic epilepsy and symptomatic epilepsy according to the existence of underlying organic brain disease. It has been said that the incidence of the symptomatic epilepsy caused by underlying organic brain disease is higher in late-onset epilepsy after the age of 20 than in childhood-onset epilepsy. CT is very sensitive and non-invasive method for detection of organic brain disease. 168 cases of late-onset epilepsy after the age of of 20 were studied by CT in recent 2 years were analyzed. The results were as follows: 1. The 3rd decade was the most frequent age group, and the ratio of male to female was 2.5 : 1. 2. Structural abnormality on brain CT was demonstrated in 51.8% of the patient. 3. The older onset of age was, the higher the ratio of abnormal CT findings, except 5th decade which showed less CT abnormality than 4th decade. 4. The most frequent history related to epilepsy was trauma. 63.1% of patients had no relevant history: and they showed CT findings of brain tumor, atrophy and infraction in decreasing order of frequency. 5. Abnormal CT findings was demonstrated in 49.2% of normal neurologic examination and in 46.4% of normal EEG study. 6. The most frequent lesion of abnormal CT scan in late-onset epilepsy was 30 cases (18.4%) of brain atrophy. The next frequent lesion was 18 cases (10.7%) of brain tumor. Infarction, parasites and calcification were other frequent lesions

    The term idiopathic focal epilepsies of childhood (IFE) is not formally recognised by the ILAE in its 2010 revision (Berg et al., 2010), nor are its members and boundaries precisely delineated. The IFEs are amongst the most commonly encountered epilepsy syndromes affecting children. They are fascinating disorders that hold many "treats" for both clinicians and researchers. For example, the IFEs pose many of the most interesting questions central to epileptology: how are functional brain networks involved in the manifestation of epilepsy? What are the shared mechanisms of comorbidity between epilepsy and neurodevelopmental disorders? How do focal EEG discharges impact cognitive functioning? What explains the age-related expression of these syndromes? Why are EEG discharges and seizures so tightly locked to slow-wave sleep? In the last few decades, the clinical symptomatology and the respective courses of many IFEs have been described, although they are still not widely appreciated beyond the specialist community. Most neurologists would recognise the core syndromes of IFE to comprise: benign epilepsy of childhood with centro-temporal spikes or Rolandic epilepsy (BECTS/RE); Panayiotopoulos syndrome; and the idiopathic occipital epilepsies (Gastaut and photosensitive types). The Landau-Kleffner syndrome and the related (idiopathic) epilepsy with continuous spikes and waves in sleep (CSWS or ESES) are also often included, both as a consequence of the shared morphology of the interictal discharges and their potential evolution from core syndromes, for example, CSWS from BECTS. Atypical benign focal epilepsy of childhood also has shared electro-clinical features warranting inclusion. In addition, a number of less well-defined syndromes of IFE have been proposed, including benign childhood seizures with affective symptoms, benign childhood epilepsy with parietal spikes, benign childhood seizures with frontal or midline spikes, and benign focal seizures of adolescence.

    The "severity" of a disease is a relative expression and its definition will vary depending on the perspective of the observer. The patient's subjective perception of the disease, the way it is regarded socially by the community, and the doctor's objective assessment rarely coincide. In fact, they are frequently diametrically opposed. As far as the patient's personal perception of epilepsy is concerned, there has apparently been no satisfactory attempt thus far at a systematic grading of the subjective handicap, despite the growth of interest in psychological matters and the self-help movement. Similarly, social ability or disability cannot be adequately assessed on the basis of medical criteria such as frequency and type of seizures. We present a grading system which will serve as an example of an appropriate method of assessing social abilities, and which will permit the patient's occupational potential to be estimated in relation to the risk of accidents resulting from seizures. From the medical point of view, the impairment of a patient's abilities due to epilepsy is a function of the patient's responsiveness to treatment. We present a critical review of the factors which have an effect on the therapeutic prognosis: the causes of epilepsy, underlying structural lesions, the incidence of convulsive status epilepticus, various types of attacks, and the different epileptic syndromes. Taking two examples--epilepsy presenting in the form of absence and epilepsy with complex focal seizures--we show that ultimately the "severity of epilepsy" can only be defined from the medical standpoint on the basis of several factors whose value is of a predictive nature.

    Since many of the children with BCECTSs display electrical status epilepticus during sleep and many present with different comorbidities, mainly ADHD and behavioral disturbances, clinicians are often confronted with the dilemma of how aggressive they should be with their efforts of normalizing the EEG. We conducted a retrospective study by screening medical records of all consecutive patients with BCECTSs, spike-wave index (SWI) >30%, and ADHD/ADD that were evaluated in our pediatric epilepsy service and were followed up for at least two years. Patients with neurocognitive deterioration detected by formal testing were excluded. A total of 17 patients with mean age of 6.9years at BCECTS diagnosis were identified. The patients' mean SWI was 60% and that dense electrical activity lasted 1.5years on average (range: 1-4.5years). Six children were formally diagnosed with learning disabilities in addition to ADD/ADHD. All of them were treated with an average of three antiepileptic medications, mainly for the purpose of normalizing the EEG, but none of them was treated with steroids or high-dose diazepam. The mean duration of follow-up was 5.5years. A cognitive or behavioral deterioration was not detected in any of them. Our data suggest that when treating a child with BCECTSs, high SWI, and school difficulties, the most critical parameter that determines the necessity of using second-line antiepileptic agents such as steroids or high-dose diazepam is a formal psychological evaluation that proves cognitive (I.Q.) decline. Otherwise, these agents may be avoided. PMID:25678032

    Full Text Available Objective: to optimize patient management tactics and disease prognosis, by detecting the regularities of the course of epilepsy during various age periods. Patients and methods. The results of following up 1632 patients with epilepsy in the Samara Region were given. Among them, there were 865 (53.0% men and 767 (47.0% women. The classification of epilepsy and epileptic syndromes (New Delhi, 1989 was used to establish the diagnosis. Each patient underwent neurological evaluation, electroencephalography (EEG and video-EEG monitoring, studies of long-latency visual evoked potentials, as well as neuroimaging examinations (brain computed tomography and magnetic resonance imaging (MRI. Factor and principal component analysis and logistic regression were used to make a mathematical model to predict remission in epilepsy. Results. The specific features of the occurrence and course of epilepsy in various age periods were analyzed. According to the results of mathematical simulation, the age at the onset of late epilepsy can be considered to be 29 years. Remission of epilepsy was more frequently attained and absolute resistance was less frequently observed in the younger age group, except for infants with catastrophic epilepsy and epileptic syndromes. There were fewer remissions and much more patients with relative and absolute resistance and rare seizures in the older age group. Epilepsy in young patients is that of the immature brain and epilepsy of adulthood (late epilepsy of the involutional brain. Conclusion. Epilepsy runs a benign course in patients who fell ill in adolescence or adulthood and have minimal brain structural changes, as evidenced by MRI. Marked brain morphological changes most frequently determine the drug-resistant course of epilepsy, manifesting in early childhood and at an elderly age.

Vinte crianças foram submetidas ao Teste de Desempenho Escolar (TDE e comparadas a crianças sadias pareadas por idade e escolaridade. Foram estudadas as relações entre o TDE e a lateralidade do foco e o número de descargas ao eletrencefalograma. As crianças com EBICT tiveram, de modo significativo, mais freqüentemente do que as sadias, desempenho inferior no subteste de leitura e no escore total. As crianças com desempenho inferior em leitura apresentaram maior número de descargas do que aquelas com desempenho médio e superior. Não houve diferenças no TDE segundo a lateralidade do foco. O número de descargas, ao interferir com a função cerebral, pode ser um fator a explicar o desempenho mais baixo na leitura.Neuropsychological implications of benign childhood epilepsy with centrotemporal spikes-rolandic spikes (BECTS have not been adequately investigated. The aim of this study was to compare the results in a school performance test of patients with BECTS and normal age-matched controls. A total of 20 children with BECTS and 20 normal controls were submitted to anamnesis, clinical evaluation, Raven test, school performance test (SPT, digital electroencephalogram and quantitative electroencephalogram analysis. Comparing with normal controls, children with BECTS showed significantly lower SPT results, especially in reading test. There was an association between the higher number of rolandic spikes and inferior performance in SPT reading test. These findings suggest that discharges may be a factor in the genesis of lower performance in reading test in children with BECTS.

Paroxismal events can resemble epileptic seizures, however, some epileptic seizures, especially benign occipital childhood epilepsies can imitate migraine, cycling vomiting or encephalitis. Objective. The aim of this study was evaluation of clinical and electroencephalographic (EEG features and outcome in children with benign occipital childhood epilepsies. Methods. Investigation included 18 patients with benign occipital childhood epilepsies hospitalized in the period from 2007 to 2010. The diagnosis was based on clinical and EEG characteristics of seizures, while treatment included acute therapy for seizures and chronic antiepileptic drugs. Prognosis was analyzed in terms of neurological outcome and seizure recurrence rate. Results. Benign occipital childhood epilepsy with early onset was diagnosed in 15 children. Vegetative symptoms, mostly ictal vomiting (13, eye deviation and loss of consciousness (13 dominated in the clinical presentation. The most frequent EEG findings showed occipital epileptic discharges. Benign occipital childhood epilepsy with late onset was diagnosed in three cases. Seizures were manifested by visual hallucinations, headache and secondary generalized convulsions. All three patients were administered chronic antiepileptic drugs and had good outcome. Conclusion. In our patients, clinical manifestations of benign occipital epilepsies had some similarities with clinical features of migraine and encephalitis. It could explain misdiagnosis in some of them. Knowledge about main features and differences between each of these disorders is crucial for making appropriate diagnosis.

    The history of eponyms for epilepsy in the lands of the Eastern globe present the portrait of the attitudes of both the laymen and skilled people towards the disease and patient, as well as to the Nature itself. As opposed to the West which during the Middle ages changed its concepts of epilepsy as the organic brain disease for the sublime 'alchemic' position, the people of the East were more prone to consider from the beginning of their civilization till the XIX century that epilepsy is the consequence of the evanescent spiritual and extracorporal forces which by themselves were out of their reach. As compared to the western civilization, the historical resources are, often as a consequence of a linguistic barriers, more scarce-as consequently is the number of eponyms, but are nevertheless picturesque. The medical science from Babylonian period presumed that epileptic manifestations are the consequence of the demonic or ill spiritual actions. There existed an attitude that at the beginning of an epileptic attack the patient was possessed by a demon (the Akkadic, i.e., Babylonian verb "sibtu" denoting epilepsy, had the meaning "to seize" or "to be obsessed"); at the end of the clonic phase the demon departed from the body. Different demons were responsible for different forms of epilepsy such as nocturnal and children epilepsy, absence epilepsy and pure convulsions, simple and complex automatisms, and gelastic epilepsy. Thus, the doctors from the period of Babylon aside from making primordial classification of epilepsies, knew about their clinical picture (prodromal symptoms and aura, Jackson's epilepsy. Todd's paralysis), postictal phenomena and intericatl emotional instability; provocative factors were also known (sleep deprivation, emotions, as well as alcohol, albeit in a negative sense-as a cure for epilepsy). There is no doubt than in the period of Babylon the clinical picture of serial fits and its progress to status epilepticus were clearly recognized and

  9. A study of brain MRI findings in children with epilepsy

    International Nuclear Information System (INIS)

    Magnetic resonance imaging in the brain was performed in 293 patients with childhood-onset (<15 y.o.) epilepsy who had been classified into 4 groups, idiopathic localization-related epilepsy (ILRE), 78 patients; idiopathic generalized epilepsy (IGE), 116 patients; symptomatic localization-related epilepsy (SLRE), 68 patients and symptomatic generalized epilepsy (SGE), 31 patients, with the Classification of Epilepsies and Epileptic Syndrome (1989 International League Against Epilepsy). The examination was performed with a 1.5 T magnet. One hundred twenty-five patients (42.7%) showed abnormal findings, and the incidence in each group was as follows: Idiopathic epilepsy: The rate of abnormal findings in the ILRE and IGE groups was 21.8% and 20.7%, respectively. Most of the abnormal findings were secondary changes, such as diffuse or localized brain atrophy. Of the congenital abnormalities, the main finding was arachnoid cyst. Symptomatic epilepsy: The rate of abnormality in the SLRE patients was 88.2%, and 85% of the findings were secondary changes, i.e., brain atrophy, or degeneration of the white matter. In the SGE group, the rate was 77.4%, with an almost equal percentage of congenital and secondary changes. Of 255 patients who were examined by electroencephalography (EEG) on the same day as MRI, about 50% showed a correlation between the EEG records and the MRI abnormalities. However, only 8 patients showed a correlation in localization between the EEG and MRI abnormalities. (author)

    Full Text Available Reflex epilepsy is the commonest form of epilepsy in which seizures are provoked by specific external stimulus. Photosensitive reflex epilepsy is provoked by environmental flicker stimuli. Video game epilepsy is considered to be its variant or a pattern sensitive epilepsy. The mean age of onset is around puberty and boys suffer more commonly as they are more inclined to play video games. Television set or computer screen is the commonest precipitants. The treatment remains the removal of the offending stimulus along with drug therapy. Long term prognosis in these patients is better as photosensitivity gradually declines with increasing age. We present two such case of epilepsy induced by video game.

    Objective To describe clinical characteristics and immunotherapy responses in patients with autoimmune epilepsy. Design Observational, retrospective case series. Setting Mayo Clinic Health System. Patients Thirty-two patients with an exclusive (n=11) or predominant (n = 21) seizure presentation in whom an autoimmune etiology was suspected (on the basis of neural autoantibody [91%], inflammatory cerebrospinal fluid [31%], or magnetic resonance imaging suggesting inflammation [63%]) were studied. All had partial seizures: 81% had failed treatment with 2 or more anti-epileptic drugs and had daily seizures and 38% had seizure semiologies that were multifocal or changed with time. Head magnetic resonance imaging was normal in 15 (47%) at onset. Electroencephalogram abnormalities included interictal epileptiform discharges in 20; electrographic seizures in 15; and focal slowing in 13. Neural autoantibodies included voltage-gated potassium channel complex in 56% (leucine-rich, glioma-inactivated 1 specific, 14; contactin-associated proteinlike 2 specific, 1); glutamic acid decarboxylase 65 in 22%; collapsin response-mediator protein 5 in 6%; and Ma2, N-methyl-D-aspartate receptor, and ganglionic acetylcholine receptor in 1 patient each. Intervention Immunotherapy with intravenous methylprednisolone; intravenous immune globulin; and combinations of intravenous methylprednisolone, intravenous immune globulin, plasmapheresis, or cyclo-phosphamide. Main Outcome Measure Seizure frequency. Results After a median interval of 17 months (range, 3–72 months), 22 of 27 (81%) reported improvement postimmunotherapy; 18 were seizure free. The median time from seizure onset to initiating immunotherapy was 4 months for responders and 22 months for nonresponders (P<.05). All voltage-gated potassium channel complex antibody–positive patients reported initial or lasting benefit (P<.05).

    伴中央颞部棘波良性儿童癫痫(BECTS)是最常见的原发性癫痫,也是小儿癫痫最常见的类型之一.传统观点认为BECTS患儿无认知功能的损害,但近年的研究表明患该病的儿童与健康同龄儿童相比存在更多的学习记忆等方面的问题.而脑电图是诊断该病的必不可少的辅助检查,如果从脑电图上能够发现其与认知损害之间的联系,对早用药或康复干预以提高患儿的生活质量及其回归社会有很大帮助.%Benign epilepsy of childhood with centrotemporal spikes( BECTS )is the most common idiopathic epilepsy and also the most common type of epilepsy in childhood. Traditionally, it is considered that children with BECTS have no cognitive impairment. However, some recent studies show BECTS patients have more difficulties in learning and memory compared to age-matched healthy children. Electroencephalography( EEG )is a required adjuvant diagnostic tool for BECTS. It is likely that the identification of cognitive impairment with EEG for the early intervention with medication or rehabilitation is helpful for the improvement of quality of life and reintegration to society in BECTS patients.

    The term idiopathic focal epilepsies of childhood (IFE) is not formally recognised by the ILAE in its 2010 revision (Berg et al., 2010), nor are its members and boundaries precisely delineated. The IFEs are amongst the most commonly encountered epilepsy syndromes affecting children. They are fascinating disorders that hold many "treats" for both clinicians and researchers. For example, the IFEs pose many of the most interesting questions central to epileptology: how are functional brain networks involved in the manifestation of epilepsy? What are the shared mechanisms of comorbidity between epilepsy and neurodevelopmental disorders? How do focal EEG discharges impact cognitive functioning? What explains the age-related expression of these syndromes? Why are EEG discharges and seizures so tightly locked to slow-wave sleep? In the last few decades, the clinical symptomatology and the respective courses of many IFEs have been described, although they are still not widely appreciated beyond the specialist community. Most neurologists would recognise the core syndromes of IFE to comprise: benign epilepsy of childhood with centro-temporal spikes or Rolandic epilepsy (BECTS/RE); Panayiotopoulos syndrome; and the idiopathic occipital epilepsies (Gastaut and photosensitive types). The Landau-Kleffner syndrome and the related (idiopathic) epilepsy with continuous spikes and waves in sleep (CSWS or ESES) are also often included, both as a consequence of the shared morphology of the interictal discharges and their potential evolution from core syndromes, for example, CSWS from BECTS. Atypical benign focal epilepsy of childhood also has shared electro-clinical features warranting inclusion. In addition, a number of less well-defined syndromes of IFE have been proposed, including benign childhood seizures with affective symptoms, benign childhood epilepsy with parietal spikes, benign childhood seizures with frontal or midline spikes, and benign focal seizures of adolescence.

    Persons with epilepsy need adequate advice and effective counselling about issues such as marriage, pregnancy, risks of inheriting epilepsy, driving, employment and antiepileptic drug withdrawal, because these persons are not receiving important information and education about their condition and possible adverse effects of treatment. Furthermore, women with epilepsy have increased rates of pregnancy complications and poor fetal outcomes including congenital malformations and developmental delay related to both their epilepsy and antiepileptic drugs. However, approximately 90% of all women with epilepsy undergo normal pregnancy and give birth to children free of birth defects. Pregnancy is generally safe in women with epilepsy. The study of long-term prognosis of childhood-onset epilepsy in Japan shows that the majority of these patients have lower levels of educational background as well as employment and marital status compared with the general population (Wakamoto H. et al). Of patients with epilepsy, 60% to 70% achieve control with antiepileptic medication. However, several antiepileptic drug withdrawal studies show variable rates of success, with relapse rates ranging from 12% to 63% (Britton J.W.). Driving is listed as major problem in persons with epilepsy. However, the patients with seizure-free more than two years have been able to get the driver's license since June, 2002. Social attitudes towards epilepsy cause more distress to the patient than the disease itself. We should realize that persons with epilepsy are normal or near-normal. To ameliorate the social stigma against epilepsy, continuous and repetitive educational efforts would be needed.

Comprehension of the complex mechanisms underlying epileptogenesis and seizure generation in temporal lobe epilepsy and other forms of epilepsy cannot be fully acquired in clinical studies with humans. As a result, the use of appropriate animal models is essential. Some of these models replicate the natural history of symptomatic focal epilepsy with an initial epileptogenic insult, which is followed by an apparent latent period and by a subsequent period of chronic spontaneous seizures. Seizures are a combination of electrical and behavioral events that are able to induce chemical, molecular, and anatomic alterations. In this review, we summarize the most frequently used models of chronic epilepsy and models of acute seizures induced by chemoconvulsants, traumatic brain injury, and electrical or sound stimuli. Genetic models of absence seizures and models of seizures and status epilepticus in the immature brain were also examined. Major uses and limitations were highlighted, and neuropathological, behavioral, and neurophysiological similarities and differences between the model and the human equivalent were considered. The quest for seizure mechanisms can provide insights into overall brain functions and consciousness, and animal models of epilepsy will continue to promote the progress of both epilepsy and neurophysiology research.Keywords: epilepsy, animal model, pilocarpine, kindling, neurodevelopment

    Objective To understand the current status of treatment and the related costs of children in a major pediatric epilepsy center, and to analysis related factors. It was hoped that the study can provide basis for health policy improvement. Methods Cases were collected in out - patient clinics Department of Pediatrics in Peking University First Hospital from Apr. 2010 to Jan. 2011, with duration of antiepileptic therapy for at least 1 year. Questionnaires were filled by the parents. The content of the questionnaire was as follows: the basic information of the children,disease - related information, treatment - related information, treatment - related costs. The seizure frequency and treatment - related costs involved in the questionnaire were retrospective survey for the past year. Then appropriate statistical methods were used to describe and analyse basic demographic characteristics,disease,treatment costs,cost structure ratio,and related factors. Results The median of direct cost was 6 680 yuan (400 -86 728 yuan) .indirect cost was 364 yuan (0-3 640 yuan) ,and total cost was 7 336 yuan (660 -88 808 yuan). The constituent ratio of the total cost varied among the 209 cases, with the median of direct cost 94. 59% (50. 85% -100.00% ) ,and indirect cost 5.41% (0-49. 15% ).The cost of anti -epileptic drugs( AEDs) .inspection fees and travel expenses were the major components of the direct costs. With or without seizures, with or without new AEDs, age, geographical distribution, and disease courses were related factors. Conclusions This is the first study on the cost for childhood epilepsy with relatively large sample size in China. The treatment of children with epilepsy causes a heavy burden on family and society, which accounted for 28.68% of gross national product per capita. There is an urgent need to develop policies to reduce the burden for patients' family.%目的 了解目前北京大型三级甲等医院小儿癫(痫)中心就诊的癫(痫)患者治疗相关成

    Objective To investigate the clinical, electroencephalograghy (EEG) features and prognosis in children with idiopathic occipital epilepsy of Gastaut (COE-G). Methods A retrospective review was conducted of 13 children patients who were diagnosed as idiopathic occipital epilepsy of gastaut (COE-G). All of them were treated with antiepileptic drugs according to the seizure typies. The prognosis were reviewed. The clinical feature and EEG were analysed. Results In total, 13 children (6 boys and 7 girls) with idiopathic childhood occipital epilepsy of gastaut were enrolled in this study. The median age at seizure onset was 8.7 years. The ictal clinical manifestations involve frequent diurnal visual seizures in all patients, elementary visual hallucinations in nine (69.2%), blindness or blurring of vision in seven (53.8%), headache in five (38.5%), and secondarily generalized tonic-clonic seizures in three (23.1%). Frequent deviation of eyes and head were common, 1 patient had seizures at night also. Interictal EEG showed high-amplitude spikes, spike and wave discharge on the unilateral or bilateral occipital regions which had often been induced by eyes closed, inhibited by eyes open. Posterior temporal spikes occured in 4 cases (30.1%), brief generalized discharges of spike-wave in 1 case (7.7%). Ictal EEG showed continuing low-amplitude sharp wave rhythm originated from one hemisphere of the occipital or posterior temporal lobe, with its amplitude increasing gradually and spread to the former head of the same hemisphere or lateral head of the contralateral hemisphere during progress. 11 cases (84.6%) had seizure free, in half of whom the medication was terminated in late adolescence. Most of them was treated monotherapy, some required combination therapy, 2 cases had poor response to multiple antiepileptic drugs, and 1 case had mild cognitive impairment.

    Full Text Available Mood disorders are the most common psychiatric comorbid disorder that affects quality of life and prognosis in epilepsy. The relation between depression and epilepsy is bidirectional. Not only the risk of having a depression among epilepsy cases is more than the healthy control cases, but also the risk of having epilepsy among depressive cases is more than the healthy control cases. People diagnosed with epilepsy are five times more likely than their peers to commit suicide. Moreover it seems that some epilepsy types like temporal lobe epilepsy have a much higher risk (25 times for suicide. Risk of suicide in epilepsy, which is independent from depression, increases more with the presence of depression. The common pathway between epilepsy, depression and suicide is hypofrontality and irregularity of serotonin metabolism. Contrary to depression, data on relationship between bipolar disorder and epilepsy is limited. However, mood disorder, mixed episodes with irritable character and mania are more frequent than assumed. As a matter of fact, both disorders share some common features. Both are episodic and can become chronic. Kindling phenomenon, irregularities in neurotransmitters, irregularities in voltage gate ion channels and irregularities in secondary messenger systems are variables that are presented in the etiologies of both disorders. Anticonvulsant drugs with mood regulatory effects are the common points of treatment. Understanding their mechanisms of action will clarify the pathophysiological processes. In this article, the relationhip between epilepsy and mood disorders, comorbidity, secondary states and treatment options in both cases have been discussed.

Results: The most affected ages were from 4 to 9 years and both genders were equally affected. They have higher rate of behavioral, educational, and social problems, and most likely recovering ages from the disease were from 15 to 20 years. Conclusion: These findings could contribute in diagnosis and treatment of Petit Mal Epilepsy, as it often misinterpreted as daydreaming or inattention.

  13. Epilepsy coexisting with depression.

    Depression episodes in epilepsy is the most common commorbidity, affecting between 11% and 62% of patients with epilepsy. Although researchers have documented a strong association between epilepsy and psychiatric comorbidities, the nature of this relationship is poorly understood. The manifestation of depression in epilepsy is a complex issue having many interacting neurobiological and psychosocial determinants, including clinical features of epilepsy (seizure frequency, type, foci, or lateralization of foci) and neurochemical or iatrogenic mechanisms. Other risk factors are a family history of psychiatric illness, particularly depression, a lack of control over the seizures and iatrogenic causes (pharmacologic and surgical). In addition, treatment with antiepileptic drugs (AEDs) as well as social coping and adaptation skills have also been recognised as risk factors of depression associated with epilepsy. Epilepsy may foster the development of depression through being exposed to chronic stress. The uncertainty and unpredictability of seizures may instigate sadness, loneliness, despair, low self-esteem, and self-reproach in patients with epilepsy and lead to social isolation, stigmatization, or disability. Often, depression is viewed as a reaction to epilepsy's stigma and the associated poor quality of life. Moreover, patients with epilepsy display a 4-5 higher rate of depression and suicide compared with healthy population. PMID:27634589

    Epilepsy is one of the most common neurological disorders. Global neurological knowledge is essential for differential diagnosis of epileptic syndromes due to the diversity of ictal semiology, causes and syndromes. Neurologists play an important role in planning the medical care for patients with epilepsy, as medication is the most fundamental therapeutic strategy. Some patients with early-onset epilepsy require joint care by pediatric neurologists, those with intractable epilepsy by neurosurgeons, and those with psychological comorbidity by psychiatrists, and neurologists should play a coordinating role. While there is a great need for neurologists to participate in epilepsy care, neurologists in Japan currently do not participate substantially in the epilepsy management system. It is necessary to train more neurologists who can provide epilepsy care and conduct basic and clinical research on epilepsy by providing continuous education on epilepsy for general neurologists as well as pre- and post-graduate medical students. Most of the patients who require long-term treatment experience many medical problems and social handicaps, such as adverse effects of medication, social stigma, educational disadvantages and difficulties in obtaining driver's license. To improve the quality of life of patients with epilepsy, it is desirable to build broad medical-social networks participated by patients, doctors, neurological nurses, psychologists, social workers, school teachers, managers of employment support facilities and care givers.

    Epilepsy is one of the most common chronic neurological disorders. Furthermore, it is associated to diminished health-related quality of life and is thus considered a major public health problem. In spite of the large number of available and ongoing development of several new antiepileptic drugs (AEDs), a high percentage of patients with epilepsy (35-40%) are resistant to pharmacotherapy. A hypothesis to explain pharmacoresistance in epilepsy suggests that overexpression of multidrug resistance proteins, such as P-glycoprotein, on the endothelium of the blood brain barrier represents a challenge for effective AED delivery and concentration levels in the brain. Proven therapeutic strategies to control pharmacoresistant epilepsy include epilepsy surgery and neuromodulation. Unfortunately, not all patients are candidates for these therapies. Nanotechnology represents an attractive strategy to overcome the limited brain access of AEDs in patients with pharmacoresistant epilepsy. This manuscript presents a review of evidences supporting this idea.

    Childhood onset epilepsy is associated with disrupted developmental integration of sensorimotor and cognitive functions that contribute to persistent neurobehavioural comorbidities. The role of epilepsy and its treatment on the development of functional integration of motor and cognitive domains is unclear. Oculomotor tasks can probe neurophysiological and neurocognitive mechanisms vulnerable to developmental disruptions by epilepsy-related factors. The study involved 26 patients and 48 typically developing children aged 8-18 years old who performed a prosaccade and an antisaccade task. Analyses compared medicated chronic epilepsy patients and unmedicated controlled epilepsy patients to healthy control children on saccade latency, accuracy and dynamics, errors and correction rate, and express saccades. Patients with medicated chronic epilepsy had impaired and more variable processing speed, reduced accuracy, increased peak velocity and a greater number of inhibitory errors, younger unmedicated patients also showed deficits in error monitoring. Deficits were related to reported behavioural problems in patients. Epilepsy factors were significant predictors of oculomotor functions. An earlier age at onset predicted reduced latency of prosaccades and increased express saccades, and the typical relationship between express saccades and inhibitory errors was absent in chronic patients, indicating a persistent reduction in tonic cortical inhibition and aberrant cortical connectivity. In contrast, onset in later childhood predicted altered antisaccade dynamics indicating disrupted neurotransmission in frontoparietal and oculomotor networks with greater demand on inhibitory control. The observed saccadic abnormalities are consistent with a dysmaturation of subcortical-cortical functional connectivity and aberrant neurotransmission. Eye movements could be used to monitor the impact of epilepsy on neurocognitive development and help assess the risk for poor neurobehavioural

    The medical management of the epilepsy syndromes of early childhood (eg, infantile spasms, Dravet syndrome, and Lennox-Gastaut syndrome) is challenging; and requires careful evaluation, classification, and treatment. Pharmacologic therapy continues to be the mainstay of management for these children, and as such it is important for the clinician to be familiar with the role of new antiepileptic drugs. This article reports the clinical trial data and personal experience in treating the severe epilepsies of childhood with the recently Food and Drug Administration-approved new antiepileptic drugs (vigabatrin, rufinamide, perampanel, and clobazam) and those in clinical trials (cannabidiol, stiripentol, and fenfluramine). Genetic research has also identified an increasing number of pediatric developmental and seizure disorders that are possibly treatable with targeted drug therapies, focused on correcting underlying neural dysfunction. We highlight recent genetic advances, and how they affect our treatment of some of the genetic epilepsies, and speculate on the use of targeted genetic treatment (precision medicine) in the future.

    Full Text Available There are 50 million people living with epilepsy worldwide, and most of them reside in developing countries. About 10 million persons with epilepsy are there in India. Many people with active epilepsy do not receive appropriate treatment for their condition, leading to large treatment gap. The lack of knowledge of antiepileptic drugs, poverty, cultural beliefs, stigma, poor health infrastructure, and shortage of trained professionals contribute for the treatment gap. Infectious diseases play an important role in seizures and long-term burden causing both new-onset epilepsy and status epilepticus. Proper education and appropriate health care services can make tremendous change in a country like India. There have been many original researches in various aspects of epilepsy across India. Some of the geographically specific epilepsies occur only in certain regions of our country which have been highlighted by authors. Even the pre-surgical evaluation and epilepsy surgery in patients with drug-resistant epilepsy is available in many centers in our country. This article attempts to provide a complete preview of epilepsy in India.

    Imaging of epilepsy patients is challenging, since epileptogenic lesions (defined as structural lesions causally related to the epilepsy syndrome) may be small and often do not change during life. Prior clinical information about the epilepsy syndrome and the semiology of the seizures is needed in order to plan the examination properly. The effort to detect an epileptogenic lesion is directed to partial (focal) epilepsy syndromes whereas - by definition - no lesion is identified in idiopathic epilepsies. Most patients with partial epilepsies suffer from mesial temporal lobe epilepsies. In these patients, 2- to 3-mm-thick T2-weighted and fluid-attenuated inversion-recovery (FLAIR) fast spin echo slices along or perpendicular to the temporal lobe length axis have the highest diagnostic efficacy. In contrast, in patients with extratemporal lobe epilepsies perpendicular FLAIR slices through the anatomic region, from which, due to clinical and EEG criteria, the seizures are likely to originate, are preferred. The imaging features of common epileptogenic lesions (hippocampal sclerosis, long-term epilepsy-associated tumours, focal cortical dysplasias, vascular malformations, encephalitis including limbic and Rasmussen's encephalitis, gyral scarring including ulegyria) are detailed in the second section of this paper.

    Children and adolescents with epilepsy frequently experience poor psychosocial outcomes due to numerous factors such as perceived stigma, behavior problems, academic difficulties, and depression. Health psychology research has documented the effectiveness of psychoeducational interventions aimed at improving psychosocial outcomes for individuals with a variety of health conditions. With increasing numbers of adolescents living with epilepsy, interest in improving the quality of life for this particular population has grown. There remains, however, a paucity of research concerning psychosocial interventions for adolescents with epilepsy. The present study outlines the development and initial implementation of a 6-week structured psychoeducational group intervention for adolescents with epilepsy and their parents. Preintervention, the QOLIE-AD-48, Childhood Depression Inventory, and Revised Children's Manifest Anxiety Scale were administered. Educational topics included medical aspects of epilepsy, healthy lifestyle behaviors, family and peer relationships, understanding self-image and self-esteem, and stress management techniques. Participants were introduced to a variety of cognitive-behavioral strategies, and were encouraged to share their own experiences with epilepsy. Feedback from adolescent and parent participants indicated that the intervention was relevant to their needs, helped them better understand their epilepsy, and allowed an opportunity for positive peer support. Also, postintervention outcome measurement indicated an overall positive trend for quality of life improvement in the adolescents.

    Some patients with idiopathic/genetic generalized epilepsy (IGE) experience visual aura, which can confuse the diagnosis. We sought to determine the frequency and characteristics of visual auras in IGE patients. Among the 176 IGE patients, 4 men and 7 women reported visual auras (mean age - 24 years). Syndromic diagnoses were juvenile myoclonic epilepsy in four, eyelid myoclonia with absences (EMA) in three, juvenile absence epilepsy in three, and other in one. Visual auras consisted of flashing lights, macropsia, illusional movements, and blindness. Eyelid myoclonia with absences was significantly more common in the group with visual aura (3 of 11 patients vs. 8 of 165 IGE patients; P=0.02). Furthermore, photosensitivity was found significantly more common in IGE patients with visual aura (90% vs 46% of the total IGE patients) (P=0.004). In conclusion, the visual auras do not exclude a diagnosis of IGE. The presence of visual aura in the EMA syndrome is also remarkable.

    Management of epilepsies in children has improved considerably over the last decade, all over the world due to the advances seen in the understanding of the patho-physiology of epileptogenesis, availability of both structural and functional imaging studies along with better quality EEG/video-EEG recordings and the availability of a plethora of newer anti-epileptic drugs which are tailormade to act on specific pathways. In spite of this, there is still a long way to go before one is able to be absolutely rational about which drug to use for which type of epilepsy. There have been a lot of advances in the area of epilepsy surgery and is certainly gaining ground for specific cases. Better understanding of the genetic basis of epilepsies will hopefully lead to a more rational treatment plan in the future. Also, a lot of work needs to be done to dispel various misunderstandings and myths about epilepsy which still exists in our country.

    Full Text Available Our aim was to clarify the correlation of attention deficit hyperactivity disorder (ADHD with epilepsy and behavior problems. This was a cross-sectional study. Sixty children with idiopathic epilepsy were interviewed using the MTA-SNAP IV Teacher and Parent Rating Scale, Vineland Adaptive Behavior Scales and Conners’ Rating Scales. We used the chi-square test to analyze the correlation of epilepsy variables in patients with and without ADHD with a significance level of 0.05. Eight patients had ADHD symptoms (13%, seven had the inattentive ADHD subtype and only three had behavioral problems. When epileptic patients with and without ADHD symptoms were compared we found no significant difference in regard to epilepsy variables. All patients were controlled and 43% were either without AED or undergoing withdrawal. Our study revealed a low comorbidity of ADHD symptoms and epilepsy due to low interference of seizures and drug treatment on the comorbid condition.

  16. Nuclear imaging in epilepsy

    International Nuclear Information System (INIS)

    Correct localization of epileptogenic zone is important for the successful epilepsy surgery. Both ictal perfusion single photon emission computed tomography (SPECT) and interictal F-18 fluorodeoxyglucose positron emission tomography (FDG-PET) can provide useful information in the presurgical localization of intractable partial epilepsy. These imaging modalities have excellent diagnostic sensitivity in medial temporal lobe epilepsy and provide good presurgical information in neocortical epilepsy. Also provide functional information about cellular functions to better understand the neurobiology of epilepsy and to better define the ictal onset zone, symptomatogenic zone, propagation pathways, functional deficit zone and surround inhibition zones. Multimodality imaging and developments in analysis methods of ictal perfusion SPECT and new PET ligand other than FDG help to better define the localization

    Defining intractable epilepsy is essential not only to identify up to 40% of patients refractory to pharmacological management, but also to facilitate selection and comparison of such patients for research purposes. The ideal definition still eludes us. Multiple factors including number of antiepileptic drug (AED) failures, seizure frequency and duration of unresponsiveness, etiology, and epilepsy syndromes are considered in formulating the definition of pharmaco-resistant epilepsy. Most definitions used in the literature agree on the number of AED failures, which seem to be 2 or 3, however, the seizure frequency and time factor are varied. The International League Against Epilepsy proposed a definition of drug-resistant epilepsy as a failure of adequate trials of 2 tolerated and appropriately chosen and used AED schedules. This for now, could provide an operational definition for clinical and research settings. However, with emergence of new data and novel treatments the criteria for intractability may change.

    In "Epilepsy is Dancing", in Antony and the Johnsons' album "The Crying Light"(2009), the lyrics and accompanying music video depicts an epileptic seizure in which the person is transferred to another beautiful and magical world. This may be called "enchanted epilepsy"; i.e., the experience of epilepsy as deeply nourishing and (positively) transforming, is conveyed not only in the lyrics but also the visual and auditory qualities of the video. The seizure in the video gives associations to Shakespeare's "A Midsummer Night's dream". If epilepsy appears in music lyrics, the focus is mostly on negative aspects of the illness, such as horror, fear and repulsive sexuality associated with the fits [1,2]. Contradictory to these lyrics, Anthony and the Johnsons' song is an example of a positive portrayal of epilepsy. It is open to a multitude of meanings, emotional valence and appraisal of epilepsy. By widening the experiential range associated with epileptic seizures, these lyrics highlight the inherently construed nature of epileptic experience. The song stands out in several ways. First, it describes epilepsy in positive terms, prioritising the euphoric, ecstatic, potentially empowering and enhancing aspects of epileptic seizures. Second, the lyrics and accompanying video point to divine experiences associated with epileptic seizures. Through the lyrics and the music video we are, as an audience, able to sense a snicket of an epileptic seizure, but also the universal experience of loosing control. PMID:26398488

    Full Text Available Introduction An epileptic seizure is a clinical event and epilepsy is rather a group of symptoms than a disease. The main features all epilepsies have in common include: spontaneous occurrence, repetitiveness, and ictal correlation within the EEG. Epilepsies are manifested with distinct EEG changes, requiring exact clinical definition and consequential treatment. Current data show that 1% of the world's population (approximately 50 million people suffers from epilepsy, with 25% of patients being refractory to therapy and requiring search for new substances in order to decrease EEG and behavioral manifestations of epilepsies. Material and methods In regard to discovery and testing of anticonvulsant substances the best results were achieved by implementation of experi- mental models. Animal models of epilepsy are useful in acquiring basic knowledge regarding pathogenesis, neurotransmitters (glutamate, receptors (NMDA/AMPA/kainate, propagation of epileptic seizures and preclinical assessment of antiepileptics (competitive and non-competitive NMDA antagonists. Results and conclusions In our lab, we have developed a pharmacologic model of a (metaphit, NMDA and remacemide-cilastatin generalized, reflex, and audiogenic epilepsy. The model is suitable for testing various anticonvulsant substances (e.g. APH, APV, CPP, Mk-801 and potential antiepileptics (e.g. DSIP, its tetra- and octaanalogues.

    Absence seizures (ASs) are the hallmark of childhood/juvenile absence epilepsy. Monotherapy with first-line anti-absence drugs only controls ASs in 50% of patients, indicating the need for novel therapeutic targets. Since serotonin family-2 receptors (5-HT2Rs) are known to modulate neuronal activity in the cortico-thalamo-cortical loop, the main network involved in AS generation, we investigated the effect of selective 5-HT2AR and 5-HT2CR ligands on ASs in the Genetic Absence Epilepsy Rats from Strasbourg (GAERS), a well established polygenic rat model of these non-convulsive seizures. GAERS rats were implanted with fronto-parietal EEG electrodes under general anesthesia, and their ASs were later recorded under freely moving conditions before and after intraperitoneal administration of various 5-HT2AR and 5-HT2CR ligands. The 5-HT2A agonist TCB-2 dose-dependently decreased the total time spent in ASs, an effect that was blocked by the selective 5-HT2A antagonist MDL11,939. Both MDL11,939 and another selective 5-HT2A antagonist (M100,907) increased the length of individual seizures when injected alone. The 5-HT2C agonists lorcaserin and CP-809,101 dose-dependently suppressed ASs, an effect blocked by the selective 5-HT2C antagonist SB 242984. In summary, 5-HT2ARs and 5-HT2CRs negatively control the expression of experimental ASs, indicating that selective agonists at these 5-HT2R subtypes might be potential novel anti-absence drugs.

    The modern treatment of epilepsy has improved considerably in all three pillars. More than a century has passed, however, since Sir Charles Locock introduced the bromides in 1857 and Sir Victor Horsely pioneered epilepsy surgery in 1886 (18). In drug therapy, the 'classic AED' of the last decades, i.e. phenobarbital (Hauptmann, 1912) and phenytoin (Putnam and Merrit, 1938) are being largely displaced by valproate (Meunir, 1963) and carbamazepine (Lorge, 1963). Only ethosuximide (Zimmermann, 1951) has continued to maintain its position in 3/s spikewave-absence epilepsy, in particular in the USA (28, 29). Although it is an excellent drug against absences, it has the unpleasant property that it may induce GM seizures and should therefore be combined with a so-called 'GM protector' (mostly phenobarbital). For this reason ethosuximide has been relegated to second place in Europe by valproate. Thus, the decision as to which AED should be employed at the outset has been simplified considerably: actually, with valproate as the drug of first choice, which displays a very broad spectrum of action, we are on the right track for virtually all forms of epilepsy, perhaps with the exception of focal epilepsy (11). Especially in the event of focal epilepsy of temporal origin we employ carbamazepine as the preparation of first choice. In some countries (Denmark), because of the less severe side effects, oxcarbazepine is already preferred (Mogens Dam, personal communication). Considerable experience and knowledge are still required, however, when resistance has developed to traditionally applied classic monotherapy. Here, the range of further treatment can also be greatly extended by the availability of the 'new AED'. A generally accepted protocol for the replacement of one preparation with another first- or second-choice drug and, above all, for the 'right' combination with third-choice preparations can as yet not be compiled. What we need here is the expert epileptologist who has

    The abilities to identify facial expression from another person's face and to attribute mental states to others refer to preserved function of the temporal lobes. In the present study, we set out to evaluate emotion recognition and social cognition in presurgical and postsurgical patients with unilateral refractory temporal lobe epilepsy (TLE). The aim of our study was to investigate the effects of TLE surgery and to identify the main risk factors for impairment in these functions. We recruited 30 patients with TLE for longitudinal data analysis (14 with right-sided and 16 with left-sided TLE) and 74 patients for cross-sectional data analysis (37 with right-sided and 37 with left-sided TLE) plus 20 healthy controls. Besides standard neuropsychological assessment, we administered an analog of the Ekman and Friesen test and the Faux Pas Test to assess emotion recognition and social cognition, respectively. Both emotion recognition and social cognition were impaired in the group of patients with TLE, irrespective of the focus side, compared with healthy controls. The performance in both tests was strongly dependent on the intelligence level. Beyond intelligence level, earlier age at epilepsy onset, longer disease duration, and history of early childhood brain injury predicted social cognition problems in patients with TLE. Epilepsy surgery within the temporal lobe seems to have neutral effect on patients' performances in both domains. However, there are a few individual patients who appear to be at risk of postoperative decline, even when seizure freedom is achieved following epilepsy surgery. PMID:24892754

    Neuropsychologists are in a unique position to be active advocates for patients with epilepsy given their unique understanding of the behavioral and cognitive effects associated the disease, its progression, and its treatment. Neuropsychologists communicate the cognitive and behavioral consequences of epilepsy and its long-term implications to patients, family, school, and employers. In this article we review factors influencing the neuropsychological profile of patients with epilepsy, and discuss common behavioral comorbidities, as well as special issues associated with school placement and long-term planning. We also include a seizure action plan, which is designed to be both an educational tool for individuals with limited epilepsy knowledge, and a way to minimize stigma associated with an event should a seizure occur during school or work.

    It is well recognized that mood disorders and epilepsy commonly co-occur. Despite this, our knowledge regarding the relationship between epilepsy and bipolar disorder is limited. Several shared features between the two disorders, such as their episodic nature and potential to run a chronic course, and the efficacy of some antiepileptic medications in the prophylaxis of both disorders, are often cited as evidence of possible shared underlying pathophysiology. The present paper aims to review the bidirectional associations between epilepsy and bipolar disorder, with a focus on epidemiological links, evidence for shared etiology, and the impact of these disorders on both the individual and wider society. Better recognition and understanding of these two complex disorders, along with an integrated clinical approach, are crucial for improved evaluation and management of comorbid epilepsy and mood disorders.

    1995-10-01

    We describe a family of 9 affected individuals in three generations with nocturnal oro-facio-brachial partial seizures, secondarily generalized partial seizures, and centro-temporal epileptiform discharges, associated with oral and speech dyspraxia and cognitive impairment. The speech disorder was prominent, but differed from that of Landau-Kleffner syndrome and of epilepsy with continuous spike and wave during slow-wave sleep. The electroclinical features of this new syndrome of autosomal dominant rolandic epilepsy resemble those of benign rolandic epilepsy, a common inherited epilepsy of childhood. This family shows clinical anticipation of the seizure disorder, the oral and speech dyspraxia, and cognitive dysfunction, suggesting that the genetic mechanism could be expansion of an unstable triplet repeat. Molecular studies on this syndrome, where the inheritance pattern is clear, could also be relevant to identifying a gene for benign rolandic epilepsy where anticipation does not occur and the mode of inheritance is uncertain.

    Full Text Available Amir M ArainVanderbilt University Medical Center, Department of Neurology, Nashville, TN, USAAbstract: Pregabalin is a new antiepileptic medication that works by binding to alpha 2 delta subunit of the voltage-dependent calcium channels present in presynaptic neurons. Its pharmacokinetic advantages include rapid and almost complete absorption, lack of protein binding, linear kinetics, absence of enzyme induction, and absence of interactions with other drugs. Pregabalin was found effective as adjunctive therapy for refractory partial-onset seizures, with up to 51% responder at a dose of 600 mg/day. The lowest effective dose was 150 mg/day. Pregabalin is also approved for treatment of painful diabetic polyneuropathy, postherpetic neuralgia and pain with fibromyalgia. Studies also suggest a beneficial effect on sleep and generalized anxiety disorders. Its main adverse effects in randomized adjunctive trials in adults have been mild to moderate. Most common side effects were dizziness, ataxia, somnolence and diplopia. Weight gain was not prominent in pivotal pregabalin trials, but was more problematic in long-term postmarketing analyses in epilepsy patients. Pregabalin, with its potent antiseizure effect, favorable pharmacokinetic profile, and effectiveness in common co-morbidities is an important addition to the treatment of epilepsy.Keywords: epilepsy, seizures, pregabalin, pharmacology, antiepileptic drugs, tolerability

  19. Coeliac disease and epilepsy.

    LENUS (Irish Health Repository)

    Cronin, C C

    2012-02-03

    Whether there is an association between coeliac disease and epilepsy is uncertain. Recently, a syndrome of coeliac disease, occipital lobe epilepsy and cerebral calcification has been described, mostly in Italy. We measured the prevalence of coeliac disease in patients attending a seizure clinic, and investigated whether cerebral calcification occurred in patients with both coeliac disease and epilepsy. Screening for coeliac disease was by IgA endomysial antibody, measured by indirect immunofluorescence using sections of human umbilical cord. Of 177 patients screened, four patients were positive. All had small-bowel histology typical of coeliac disease. The overall frequency of coeliac disease in this mixed patient sample was 1 in 44. In a control group of 488 pregnant patients, two serum samples were positive (1 in 244). Sixteen patients with both coeliac disease and epilepsy, who had previously attended this hospital, were identified. No patient had cerebral calcification on CT scanning. Coeliac disease appears to occur with increased frequency in patients with epilepsy, and a high index of suspicion should be maintained. Cerebral calcification is not a feature of our patients with epilepsy and coeliac disease, and may be an ethnically-or geographically-restricted finding.

  20. [Epilepsy and Szondi test].

    Science.gov (United States)

    Andrade, L

    1976-05-01

    After having briefly recalled the different studies of epilepsy done on the basis of the Szondi test, the author proposes to study the drive structure of three groups of epileptics (19 cases of primary generalized epilepsy, 18 cases of partial temporal lobe epilepsy, 31 cases of partial non-temporal epilepsy) with the purpose of finding possible differences in psychological drive among the three groups and, at the same time, evaluating the test's capacity for discrimination by using the statistical method. The three groups show the same type of profile generally characterized by an extreme need for acceptance and affection (h + !, C- + !) counteracted by a strong repression (hy - !, k -) resulting in agressiveness (s + !). However, statistical analysis (chi square test), the drive formula, the drive class and the EKP showed that, beyond this shared area, there are differences among the three groups. The author then attempts to sort out the meaning of these differences. Finally, based on certain passages from Szondi as well as the test results, the author puts forward an hypothesis linking the psychological drive problematic in primary generalized epilepsies to a very early disturbance in the history of the individual's psychic development, the origins of which would go back to a split in the unity between mother and child. On the other hand, drive disturbances in partial epilepsies would be considered secondary to the illness. PMID:788602

    2001-01-01

    Objective To study the clinical characteristics of 2952 patients with epilepsy who had received drug treatment from the neurology outpatient clinics of eight major hospitals in Hong Kong. Methods Retrospective review of outpatient records. Results 1601 (54.3%) males and 1351 (45.7%) females with a median age of 35.8 years (range, 10-94.8) were studied. Seizure types included generalized tonic-clonic in 80.7% of patients, complex partial in 28.3%, simple partial in 14.4%, atypical absence in 2.6% and myoclonic in 1.4%, and 30.4% of patients had more than one seizure type. EEG, CT brain, MRI brain and neuropsychological evaluation were obtained in 81.2%, 61.7%, 17.0% and 2.2% of patients, respectively. The etiology of epilepsy was cryptogenic in 59.9%, symptomatic in 35.1% and idiopathic in 3.9%; the commonest were intracranial infection, cerebral vascular disease, cranial trauma and perinatal insult. Phenytoin, carbamazepine and valproate were the most frequently used drugs and 25.9% of patients were taking more than two drugs. 48.3% of patients had active seizures in the past six months and 26.4% were considered to have unsatisfactory control of their epilepsy. Medical refractoriness of epilepsy was associated with a history of perinatal insult, intracranial infection, congenital brain malformation, intracranial neoplasm, cerebral vascular disease, hippocampal sclerosis, mental retardation and a history of status epilepticus (P<0.05). Conclusion In this local cohort of adult patients with epilepsy under specialist care, there were a considerable number of patients falling into the category of cryptogenic epilepsy. Risk factors associated with medical refractoriness are similar to previous studies.

We selected 15 papers with a total of 50 homicides.Results: We describe the case of a 47-year-old woman with drug-resistant right temporal epilepsy who developed increasing emotional lability, outbursts of anger and escalating violent behavior culminating in a violent murder. The patient was imprisoned while awaiting trial. In the interim, she underwent a successful temporal lobectomy with full resolution of seizures, interictal rage and aggressive behaviors. After the surgery, her charges were downgraded and she was transferred to a psychiatric facility.Conclusion: The aggressive behavior associated with epilepsy has been described in the literature for over a century. A link between epilepsy and aggression has been disproportionally emphasized. These patients share some common characteristics: they are usually young men with a long history of epilepsy and lower than average intelligence. The violent act is postictal, sudden-onset, more likely to occur after a cluster of seizures and is usually related with alcohol abuse.Keywords: aggression, crime, epilepsy

  13. Rhythm and blues: animal models of epilepsy and depression comorbidity.

    Science.gov (United States)

    Epps, S Alisha; Weinshenker, David

    2013-01-15

    Clinical evidence shows a strong, bidirectional comorbidity between depression and epilepsy that is associated with decreased quality of life and responsivity to pharmacotherapies. At present, the neurobiological underpinnings of this comorbidity remain hazy. To complicate matters, anticonvulsant drugs can cause mood disturbances, while antidepressant drugs can lower seizure threshold, making it difficult to treat patients suffering from both depression and epilepsy. Animal models have been created to untangle the mechanisms behind the relationship between these disorders and to serve as screening tools for new therapies targeted to treat both simultaneously. These animal models are based on chemical interventions (e.g. pentylenetetrazol, kainic acid, pilocarpine), electrical stimulations (e.g. kindling, electroshock), and genetic/selective breeding paradigms (e.g. genetically epilepsy-prone rats (GEPRs), genetic absence epilepsy rat from Strasbourg (GAERS), WAG/Rij rats, swim lo-active rats (SwLo)). Studies on these animal models point to some potential mechanisms that could explain epilepsy and depression comorbidity, such as various components of the dopaminergic, noradrenergic, serotonergic, and GABAergic systems, as well as key brain regions, like the amygdala and hippocampus. These models have also been used to screen possible therapies. The purpose of the present review is to highlight the importance of animal models in research on comorbid epilepsy and depression and to explore the contributions of these models to our understanding of the mechanisms and potential treatments for these disorders.

    2011-01-01

    Full Text Available Introduction. It is considered that around 20%-30% of patients of all ages and in all continents have wrong epilepsy diagnoses. Diagnostic and consequential therapeutic errors appear, most often, when an adequate diagnostics is not applied. Benign focal epilepsy of childhoods with centrotemporal spikes-rolandic epilepsy, brings very often to diagnostic and therapeutic problems because of persistence of epilepticforms changes in an electroencephalography (EEG recording, several years after establishment of good control over seizures. Case report. We presented 8.5 years-old girl, with the first and the only epileptic seizure at the age of 5, during her sleep. With a clear correlation of EEG record, benign rolandic epilepsy was diagnosed, so the therapy with valproate was introduced. There were no seizures after three years of its implementation. Because of epileptic-forms changes that still persisted in EEG record during her sleep, it was suggested to further use valproate. However, after reconsidering all circumstances it was concluded that the AED should bee slowly reduced up to its exclusion. After a complete stoppage of the therapy, the patient did not have any epileptic seizure for nine months, although EEG still remained pathologically changed during her sleep. Conclusion. A changed EEG record in a patient with rolandic epilepsy must not be a predictor of continuation of antiepileptic drugs therapy, after 2-3 years of successful seizures remission.

  16. Value of prophylactic epilepsy surgery in contemporary neurosurgical practice

    International Nuclear Information System (INIS)

    We have examined the value of prophylactic epilepsy surgery in diseases leading to intractable epilepsy. We reviewed 11 glioneuronal tumors (GNT) including gangliogliomas and dysembryoplastic neuroepithelial tumors, 11 cortical dysplasia (CD), and 33 cavernous angiomas (CA) diagnosed with MRI between the years 2000 and 2008 at the Department of Neurosurgery of Juntendo University in this study. We analyzed retrospectively the followings. Age of seizure onset and seizure severity. Region of each disease leading to intractable epilepsy. Seizure outcome after the surgery. Surgical morbidity. Ages of seizure onset of GNT, CD, and CA were 21.0±12.1, 1.3±7.5, 24.8±18.1 years, respectively. 81.8% of CD and GNT were intractable, however CA progresses to intractable epilepsy in 48.5%. The 66.7% of GNT with intractable seizures located in the mesial temporal lobe and 66.7% of CD had entra-temporal location. CA located in the mesial temporal lobe progressed to intractable epilepsy in 80%. Seizure free ratios of GNT, CD, and CA were 87.5%, 50.0%, 81.3%, respectively. In CDs where was impossible to carry out complete resection resulted in residual seizures. Neurological sequelae after surgery were observed in 3 cases. Morbidity ratios of motor weakness, speech difficulty, and memory disturbances are 4.6%, 4.6%, 2.3%, respectively. Majority of CD, GNT, and CA located in the mesial temporal lobe progress towards intractable epilepsy. Prophylactic epilepsy surgery by experienced surgeon with low complication rates can be an acceptable alternative for these pathological conditions. Seizure outcome of surgery for CD does not reach the success rates of those in GNT and CA. The cause of the unfavorable result in CD is the inapplicability to eloquent areas. Aggressive early surgery for CD may improve outcome considering neuronal plasticity of childhood. (author)

  17. Bmi-1 absence causes premature brain degeneration.

    Directory of Open Access Journals (Sweden)

    Guangliang Cao

    Full Text Available Bmi-1, a polycomb transcriptional repressor, is implicated in cell cycle regulation and cell senescence. Its absence results in generalized astrogliosis and epilepsy during the postnatal development, but the underlying mechanisms are poorly understood. Here, we demonstrate the occurrence of oxidative stress in the brain of four-week-old Bmi-1 null mice. The mice showed various hallmarks of neurodegeneration including synaptic loss, axonal demyelination, reactive gliosis and brain mitochondrial damage. Moreover, astroglial glutamate transporters and glutamine synthetase decreased in the Bmi-1 null hippocampus, which might contribute to the sporadic epileptic-like seizures in these mice. These results indicate that Bmi-1 is required for maintaining endogenous antioxidant defenses in the brain, and its absence subsequently causes premature brain degeneration.

    Full Text Available Background:Epilepsy is a common neurologic disorder affecting about 1% of the population (1. The prevalence of active epilepsy in Kerman is 7.87/1000 populations (2. In 23 countries of Asia the rate of epilepsy is the same as USA and Europe. Pharmacotherapy with antiepileptic drugs is the major treatment modality for epilepsy, this could occur as a result of decreased excitation concurrent with increased inhibition (3. Management of epilepsy differs from the treatment of other chronic diseases in which a single breakthrough event has a major negative effect on the quality of life.The past decade has brought many advances to the treatment of epilepsy, including many new pharmacological agents. Lamotrigine is one of the new antiepileptic drugs, which has been used more than two decades. Lamotrigine is effective in partial-onset and secondarily generalized tonic-clonic seizures, primary generalized seizures (i.e., absence seizures and primary generalized tonic-clonic seizures, atypical absence seizures, tonic / atonic seizures and Lennox-Gaustaut syndrome. It is sometimes effective for myoclonic seizures but it can worsen myoclonic seizures in some patients with juvenile myoclonic epilepsy or myoclonic epilepsy of infancy.One of the main advantages of lamotrigine is that it causes less cognitive impairment or overt sedation compared with other treatments (4. An anti-aging effect on animal model in a study has found that lamotrigine decreases mortality and increases lifespan.Lamotrigine has many side effects; the most important ones are allergic reactions, Introducing lamotrigine gradually is one of the keys to reduce the frequency and severity of allergic reactions. Although the incidence of cutaneous reactions to lamotrigine is high, the incidence of serious eruptions such as erythema multiform, Stevens-Johnson syndrome, and toxic epidermal necrolysis is low (5. In this study we evaluated the effects of lamotrigine on epileptic patients

    Full Text Available Tics are the most common forms of hyperkinesis among children and adolescents, the etiology of which is not fully clear. A study has shown a high comorbidity of tic disorders and epilepsy, as evidenced by video-EEG monitoring. In patients with tics even in the absence of epileptic seizures, epileptiform activity is an adverse predictor and a determinant of the potential risk of comorbid epilepsy especially during neuroleptic therapy. Antiepileptic drugs are the drugs of choice to treat this category of patients.

  1. Positron emission tomography in epilepsy

    International Nuclear Information System (INIS)

    Positron emission tomography (PET) was performed with the 18F-fluoro-deoxy-glucose method on 29 patients with epilepsy (generalized epilepsy, 4; partial epilepsy, 24; undetermined type, 1). The subjects were restricted to patients with epilepsy without focal abnormality on X-CT. All the patients with generalized epilepsy showed a normal pattern on PET. Fourteen out of the 24 patients with partial epilepsy and the 1 with epilepsy of undermined type showed focal hypometabolism on PET. The hypometabolic zone was localized in areas including the temporal cortex in 11 patients, frontal in 2 and thalamus in 1. The location of hypometabolic zone and that of interictal paroxysmal activity on EEG were well correlated in most patients. The patients with poorly-controlled seizure showed a higher incidence of PET abnormality (12 out of 13) than those with well-controlled seizures (2 out of 11). The incidence of abnormality on PET and MRI and the location of both abnormality were not necessarily coincident. These results indicated that the PET examination in epilepsy provides valuable information about the location of epileptic focus, and that the findings on PET in patients with partial epilepsy may be one of the good indicators about the intractability of partial epilepsy, and that PET and MRI provide complementary information in the diagnosis of epilepsy.

    Juvenile myoclonic epilepsy (JME) is a recognizable, frequent epileptic syndrome. The most typical ictal phenomenon is bilateral myoclonia without loss of consciousness (M), with most patients also presenting with generalized tonic-clonic seizures (GTCSs) and some with absence seizures (ASs). The most striking features of JME are its onset around the time of puberty and the fact that seizure episodes occur after awakening from a sleep period or in the evening relaxation period and are facilitated by sleep deprivation and sudden arousal. Photic sensitivity is common in the EEG laboratory but uncommon or unrecognized in daily life. The clinical features of JME make it easy to diagnose. In recent years, awareness of JME has increased, and patients are often accurately diagnosed clinically before confirmation by EEG. The typical circumstance at diagnosis is a first GTCS episode, and one learns during the interview that the patient has had M in the morning for some time before the GTCS episode. There are only few differential diagnoses: the adolescent-onset progressive myoclonus epilepsies, or other forms of idiopathic generalized epilepsies of adolescence. With JME being so common, we propose that a first GTCS episode in a teenager should be considered as revealing JME until proven otherwise. PMID:23756488

    Full Text Available Epilepsy is a common neurological disorder with diverse etiologies. Neuroimaging plays an important role in workup of patients with epilepsy. It helps to identify brain pathologies that require specific treatment; and also in formulating syndromic and etiological diagnoses so as to give patients and their relatives an accurate prognosis. Magnetic resonance imaging, specially the 3 tesla MRI is the imaging of choice because of its ability to detect small lesions like mesial temporal sclerosis, cortical dysplasias, small tumors, etc that are not detected by conventional MR or CT scan of brain. Identification of these lesions often helps in managing refractory epilepsies more effectively. However, cost and non-availability of MR in large part of the country necessitate the use of CT as an alternative. CT is often the initial investigation and also useful in acute situations. Functional imagings are used for pre-surgical work-up of refractory epilepsy cases with an aim to identify the epileptogenic focus and to delineate functional areas nearing the focus.

  7. Spect in epilepsy

    International Nuclear Information System (INIS)

    In the Federal Republic of Germany it is assumed that about 80 000 patients suffer from a focal form of epilepsy which can not be sufficiently controlled with medication. As potential candidates for surgery, these patients undergo stepwise monitoring procedure in which the epileptic focus is located by means of increasingly invasive methods. In Erlangen the periictal SPECT is performed, whereby the perfusion tracer is injected after onset (ictal SPECT), immediately after cessation of the seizure (postictal scan) or between the seizures (interictal scan). To administer the tracer strongly in ictal or postictal state a close functional cooperation between the neurology and nuclear medicine department must be arranged. Injection inside the monitoring unit must be attuned to federal antiradiation precaution law. In temporal lobe epilepsy, different injection-times demonstrate a large area of hyperperfusion after ictal onset, which refines in the first two postictal minutes to the generating focus together with a decreased parietal blood flow pattern. Later, the entire temporal lobe epilepsy an early tracer injection within 40 seconds has to be achieved, otherwise an ictal propagation into distant brain areas, possibly contralateral, may occur. Extratemporal epilepsy is often linked to trauma or congenital malformations, and is difficult to categorize. In difficult cases with equivocal results, efforts can be undertaken by means of receptor scintigraphy with, for example, iomazenil, to localize the focus as a cold lesion caused by neuronal loss.

    Full Text Available In children with temporal lobe epilepsy (TLE, memory deficit is not so well understood as it is in adults. The aim of this study was to identify and describe memory deficits in children with symptomatic TLE, and to verify the influence of epilepsy variables on memory. We evaluated 25 children with TLE diagnosed on clinical, EEG and MRI findings. Twenty-five normal children were compared with the patients. All children underwent a neuropsychological assessment to estimate intellectual level, attention, visual perception, handedness, and memory processes (verbal and visual: short-term memory, learning, and delayed recall. The results allowed us to conclude: besides memory deficits, other neuropsychological disturbances may be found in children with TLE such as attention, even in the absence of overall cognitive deficit; the earlier onset of epilepsy, the worse verbal stimuli storage; mesial lesions correlate with impairment in memory storage stage while neocortical temporal lesions correlate with retrieval deficits.

    OBJECTIVE: To review the relationship between calcium ion channel and epilepsy for well investigating the pathogenesis of epilepsy and probing into the new therapeutic pathway of epilepsy.DATA SOURCES: A computer-based online research Calcium ion channel and epilepsy related articles published between January 1994 and December 2006 in the CKNI and Wanfang database with the key words of "calcium influxion, epilepsy, calcium-channel blocker". The language was limited to Chinese. At the same time,related articles published between January 1993 and December 2006 in Pubmed were searched for on online with the key words of "calcium influxion, epilepsy" in English.STUDY SELECTION: The materials were selected firstly. Inclusive criteria: ① Studies related to calcium ion channel and the pat1hogenesis of epilepsy. ② Studies on the application of calcium ion channel blocker in the treatment of epilepsy. Exclusive criteria: repetitive or irrelated studies.DATA EXTRACTION: According to the criteria, 123 articles were retrieved and 93 were excluded due to repetitive or irrelated studies. Altogether 30 articles met the inclusive criteria, 11 of them were about the structure and characters of calcium ion channel, 10 about calcium ion channel and the pathogenesis of epilepsy and 9 about calcium blocker and the treatment of epilepsy.DATA SYNTHESIS: Calcium ion channels mainly consist of voltage dependent calcium channel and receptor operated calcium channel. Depolarization caused by voltage gating channel-induced influxion is the pathological basis of epileptic attack, and it is found in many studies that many anti-epileptic drugs have potential and direct effect to rivalizing voltage-dependent calcium ion channel.CONCLUSION: Calcium influxion plays an important role in the seizure of epilepsy. Some calcium antagonists seen commonly are being tried in the clinical therapy of epilepsy that is being explored, not applied in clinical practice. If there are enough evidences to

  17. The language of absence.

    Science.gov (United States)

    Gurevich, Hayuta

    2008-06-01

    This paper will focus on the concept of 'absence', which describes a continuum of non-responsiveness and misattunement of the environment in the stage of absolute dependence; it refers to concepts like lack, failure, non-recognition, impingement, neglect, tantalizing, ranging to mental, physical and sexual abuse. An extreme external absence causes shock and fear. The automatic survival response is an inner absence, an intrapsychic absence, a dissociation of parts of the self. The external and the inner absence are the negative image of each other. The concept of absence points to the synchronicity of outer and inner reality and portrays the non-responded-to needs of the self. This point of view of the development of psychopathology of the self on the basis of massive dissociation is inherently an intersubjective-field-theory. As the inner absence is created as a reaction to an absence of the other, in analysis - the analyst has an active role in reviving it. This paper will explore the language of absence, that is, the derivatives and consequences of these situations in the inner realm, and in the relations with the analyst. It is the author's contention that understanding and speaking this language has important clinical and technical implications. Understanding the language of absence enables the analyst to recognize its intersubjective and its intrapsychic presence, to provide an environment that allows for its revival, and to facilitate and regulate the annihilation anxiety that awakens when dissociated self-states are experienced. When the absence is present, i.e. when the traumatic experience and the dissociated reactions to it are experienced in an attuned relationship, it is rendered with meaning, symbolization, and validation, and enables the survival mode of dissociation to be relinquished.

    Epilepsy is one of the most common disabling neurological disorders, but significant gaps exist in our knowledge about childhood epilepsy in rural populations. The present study assessed the prevalence of pediatric epilepsy in nine low-income rural counties in the Midwestern United States overall and by gender, age, etiology, seizure type, and syndrome. Multiple sources of case identification were used, including medical records, schools, community agencies, and family interviews. The prevalence of active epilepsy was 5.0/1000. Prevalence was 5.1/1000 in males and 5.0/1000 in females. Differences by age group and gender were not statistically significant. Future research should focus on methods of increasing study participation in rural communities, particularly those in which research studies are rare.

    This study investigated the possible presence of sensory-motor developmental impairments in preschool children with epilepsy and explored epilepsy impact on their activities and quality of life and on the stress load of their family. Study participants were children aged 2-6years diagnosed with epilepsy without any other comorbidities (epi-only children). The instruments used for assessment included the Neurological, Sensory, Motor, Developmental Assessment (NSMDA) scale for sensory-motor development, the Impact of Childhood Neurologic Disability Scale (ICNDS), and the Impact of Pediatric Epilepsy Scale (IPES) for disease impact on disability and Quality of Life (QoL), as well as the Pediatric Outcomes Data Collection Instrument (PODCI) for functional health status, and the Parental Stress Scale (PSS) for the family stress load. Required data were obtained from direct testing or observation of children's activities and mother-supplied answers to questions. Eighty-two children were investigated. The NSMDA scores were in the normal development range 6-8. Significant moderate impact of the disease on disability and QoL was estimated with the ICNDS and IPES instruments. The PODCI scores were similar to healthy population levels except for the happiness dimension which was better for children with epilepsy. PSS were significantly above normal. The functional health and QoL of the children as well as their family stress were found to be positively correlated with increasing age. It is found that epilepsy does not degrade neuromotor development and functional health status of preschool epi-only children, though it has a significant impact on their neurological disability and QoL and the stress level of their families; this impact seems to decrease with age.

    Full Text Available Introduction. The treatment of epilepsy is still a major challenge. Despite the introduction of many new antiepileptic drugs, approximately 30% of patients still remain drug resistant. In the absence of a satisfactory therapy outcome, which is sometimes associated with numerous side effects, there is a need for new and effective drugs with low toxicity. Cannabinoids have been shown in preliminary animal model studies and in studies of patients with epilepsy to have antiepileptic activity.

  8. Diagnostic imaging in focal epilepsy

    International Nuclear Information System (INIS)

    Focal epilepsies account for 60% of all seizure disorders worldwide. In this review the classic and new classification system of epileptic seizures and syndromes as well as genetic forms are discussed. Magnetic resonance (MR) is the technique of choice for diagnostic imaging in focal epilepsy because of its sensitivity and high tissue contrast. The review is focused on the lack of consensus of imaging protocols and reported findings in refractory epilepsy. The most frequently encountered MRI findings in epilepsy are reported and their imaging characteristics are depicted. Diagnosis of hippocampal sclerosis and malformations of cortical development as two major causes of refractory focal epilepsy is described in details. Some promising new techniques as positron emission tomography computed tomography (PET/CT) and MR and PET/CT fusion are briefly discussed. Also the relevance of adequate imaging in focal epilepsy, some practical points in imaging interpretation and differential diagnosis are highlighted. (author)

  9. Confronting the stigma of epilepsy

    Full Text Available Stigma and resultant psychosocial issues are major hurdles that people with epilepsy confront in their daily life. People with epilepsy, particularly women, living in economically weak countries are often ill equipped to handle the stigma that they experience at multiple levels. This paper offers a systematic review of the research on stigma from sociology and social psychology and details how stigma linked to epilepsy or similar conditions can result in stereotyping, prejudice and discrimination. We also briefly discuss the strategies that are most commonly utilized to mitigate stigma. Neurologists and other health care providers, social workers, support groups and policy makers working with epilepsy need to have a deep understanding of the social and cultural perceptions of epilepsy and the related stigma. It is necessary that societies establish unique determinants of stigma and set up appropriate strategies to mitigate stigma and facilitate the complete inclusion of people with epilepsy as well as mitigating any existing discrimination.

    Full Text Available Temporal lobe epilepsy represents the largest group of patients with treatment resistant/medically intractable epilepsy undergoing epilepsy surgery. The underpinnings of common forms of TLE in many instances begin in early life with the occurrence of an initial precipitating event. The first epileptic seizure often occurs after a variable latency period following this event. The precise natural history and progression following the first seizure to the development of TLE, its subsequent resolution through spontaneous remission or the development of treatment resistant epilepsy remain poorly understood. Our present understanding of the role played by these initial events, the subsequent latency to development of temporal lobe epilepsy, and the emergence of treatment resistance remains incomplete. A critical analysis of published data suggest that TLE is a heterogeneous condition, where the age of onset, presence or absence of a lesion on neuroimaging, the initial precipitating event, association with febrile seizures, febrile status epilepticus, and neurotropic viral infections influence the natural history and outcome. The pathways and processes through which these variables coalesce into a framework will provide the basis for an understanding of the natural history of TLE. The questions raised need to be addressed in future prospective and longitudinal observational studies.

    2014-01-01

    Background: Epilepsy associated with Prader-Willi syndrome (PWS) represents an early and important complication, often not clearly reported and described in the literature. Consequently, there are controversial data about the clinical characteristics of epilepsy and electroencephalographic (EEG) abnormalities found in these patients. Data sources: Based on recent original publications, we have reviewed the different types of seizures and EEG findings in PWS patients, the response to antiepileptic treatment, and the prognosis of epilepsy. Results: The frequency of epilepsy in PWS patients ranges from 4% to 26%. The types of seizure include generalized tonic-clonic seizures, complex partial seizures, atypical absence, staring spells, and myoclonic, tonic and hemiclonic seizures, but the most frequent type is focal epilepsy. Status epilepticus has never been reported. EEG abnormalities are not typical but variable in different patients. However, generalized and focal discharges are the most frequently reported findings. There is no evidence of relationship between the course of epilepsy and frequency, morphology and spread of EEG discharges. However, epilepsy in PWS patients is usually responsive to antiepileptic monotherapy with rapid seizure control and a good outcome. Conclusions: The frequency of epilepsy is higher in PWS patients than in general populations and this complication can be a challenge for the clinicians of these patients. Prospective studies are needed to confirm the good long-term prognosis.

    Epilepsy is an uncommon comorbidity of Parkinson's disease (PD) and has been considered not directly associated with PD. We present five patients (3 men and 2 women; ages 49–85) who had concomitant PD and cryptogenic epilepsy. Although rare, epilepsy can coexist with PD and their coexistence may influence the progression of PD. While this may be a chance association, an evolving understanding of the neurophysiological basis of either disease may suggest a mechanistic association. PMID:27688919

    Full Text Available This study evaluated the sequential motor manual actions in children with benign focal epilepsy of childhood with centrotemporal spikes (BECTS and compares the results with matched control group, through the application of Luria's fist-edge-palm test. The children with BECTS underwent interictal single photon emission computed tomography (SPECT and School Performance Test (SPT. Significant difference occurred between the study and control groups for manual motor action through three equal and three different movements. Children with lower school performance had higher error rate in the imitation of hand gestures. Another factor significantly associated with the failure was the abnormality in SPECT. Children with BECTS showed abnormalities in the test that evaluated manual motor programming/planning. This study may suggest that the functional changes related to epileptiform activity in rolandic region interfere with the executive function in children with BECTS.Esse estudo avaliou ações motoras manuais sequenciais em crianças com epilepsia focal benigna da infância com descarga centrotemporal (EBICT e comparou os resultados com o grupo controle pareado, através do teste de Lúria (punho-lado-palma.

    Since the first case of videogame (VG) epilepsy was reported in 1981, many cases of seizures triggered by VGs were reported, not only in photosensitive, but also in non-photosensitive children and adolescents with epilepsy. We provide an overview of the literature with overall conclusions and recommendations regarding VG playing. Specific preventive measures concerning the physical characteristics of images included in commercially available VGs (flash rate, choice of colors, patterns, and contrast) can lead in the future to a clear decrease of this problem. In addition to the positive effect of such measures, the collaborative studies performed in France and in the rest of Europe have stressed the importance of a safe distance to the screen of > or = 2 m, and the less provocative role of 100-Hz screens.

    Full Text Available BACKGROUND: The impact of a scientific article is proportional to the citations it has received. In this study, we set out to identify the most cited works in epileptology in order to evaluate research trends in this field. METHODS: According to the Web of Science database, articles with more than 400 citations qualify as "citation classics". We conducted a literature search on the ISI Web of Science bibliometric database for scientific articles relevant to epilepsy. RESULTS: We retrieved 67 highly cited articles (400 or more citations, which were published in 31 journals: 17 clinical studies, 42 laboratory studies, 5 reviews and 3 classification articles. Clinical studies consisted of epidemiological analyses (n=3, studies on the clinical phenomenology of epilepsy (n=5 – including behavioral and prognostic aspects – and articles focusing on pharmacological (n=6 and non-pharmacological (n=3 treatment. The laboratory studies dealt with genetics (n=6, animal models (n=27, and neurobiology (n=9 – including both neurophysiology and neuropathology studies. The majority (61% of citation classics on epilepsy were published after 1986, possibly reflecting the expansion of research interest in laboratory studies driven by the development of new methodologies, specifically in the fields of genetics and animal models. Consequently, clinical studies were highly cited both before and after the mid 80s, whilst laboratory researches became widely cited after 1990. CONCLUSIONS: Our study indicates that the main drivers of scientific impact in the field of epileptology have increasingly become genetic and neurobiological studies, along with research on animal models of epilepsy. These articles are able to gain the highest numbers of citations in the time span of a few years and suggest potential directions for future research.

  5. Neuroreceptor imaging in epilepsy

    International Nuclear Information System (INIS)

    The neurochemical processes that mediate seizures in humans are not fully understood. PET has contributed to our understanding of the neurochemical abnormalities of epilepsy with studies of cerebral metabolism and, more recently, regional neuroreceptor binding. We have focused on inhibitory neurotransmitter receptors that may (1) be decreased, thus facilitating seizure initiation, or (2) increase in response to seizure activity. Opiate receptors are believed to mediate anticonvulsant effects of the endogenous opioids. Accordingly, [11 C]carfentanil, a ligand selective for the mu-opiate receptor, displays increased binding in temporal neocortex ipsilateral to seizure foci in complex partial epilepsy. This finding is consistent with activation of the endogenous opiate system in response to seizure activity. [11C]diprenorphine, a ligand that labels mu-, delta- and kappa-opiate receptors with equal affinity, shows little or no change in temporal cortex. Together, these findings suggest a decrease in delta- or kappa-receptors. The development of delta- and kappa-selective receptor ligands will help to elucidate the involvement of these opiate receptors in human epilepsy. The benzodiazepine-GABA receptor complex is the most prevalent in mediating inhibitory brain processes. Use of the benzodiazepine (BZD) receptor ligand [11C]RO 15-1788 has shown decreases in BZD receptors in human epilepsy in one study, but this has not been observed in a current study. Thus, the existence of reduced inhibitory processes that might enhance seizure initiation remains uncertain at present. Future studies of receptors for excitatory transmitters will provide additional insight into alternate factors potentially responsible for the initiation of seizures

    2016-09-01

    Until recently, analysis of the mechanisms underlying epilepsy was centered on neuron dysfunctions. Accordingly, most of the available pharmacological treatments aim at reducing neuronal excitation or at potentiating neuronal inhibition. These therapeutic options can lead to obvious secondary effects, and, moreover, seizures cannot be controlled by any known medication in one-third of the patients. A purely neurocentric view of brain functions and dysfunctions has been seriously questioned during the past 2 decades because of the accumulation of experimental data showing the functional importance of reciprocal interactions between glial cells and neurons. In the case of epilepsy, our current knowledge of the human disease and analysis of animal models clearly favor the involvement of astrocytes and microglial cells during the progression of the disease, including at very early stages, opening the way to the identification of new therapeutic targets. Purinergic signaling is a fundamental feature of neuron-glia interactions, and increasing evidence indicates that modifications of this pathway contribute to the functional remodeling of the epileptic brain. This Review discusses the recent experimental results indicating the roles of astrocytic and microglial P2X and P2Y receptors in epilepsy. © 2016 Wiley Periodicals, Inc. PMID:27302739

  8. Epilepsy and radiological investigations

    International Nuclear Information System (INIS)

    Epilepsy is a heterogenous group of disorders with multiple causes. Clinical management of epilepsy patients requires knowledge of seizure syndromes, causes, and imaging features. The aim of radiological investigations is to recognize the underlying cause of epilepsy. The main indications for neuroimaging studies are partial and secondarily generalized seizures, patients with neurological signs and intractable seizures, and patients with focal signs on EEG. Partial seizures of any type are more likely to be associated with a focus that may be identified on neuroimaging. MRI is the method of choice for evaluating structural abnormalities of the brain. High resolution MRI and dedicated imaging technique are needed for detection of subtle pathological changes as cortical dysplasias and temporal medial sclerosis. Other lesions that may be detected include neoplasms, vascular malformations, destructive lesions following brain injury, stroke, infection, etc. CT continues to be the technique for the investigation of patients with seizures under certain conditions. New techniques such as functional MRI, MR spectroscopy, SPECT, receptor PET and magnetic source imaging are becoming clinical tools for improving diagnosis

    Full Text Available Nonpharmacological treatment of epilepsy includes surgery, vagal nerve stimulation, ketogenic diet, and other alternative/complementary therapies, e.g., yoga, Ayurveda, electroencephalography (EEG biofeedback technique, aerobic exercise, music therapy, transcranial magnetic stimulation, acupuncture, and herbal remedies (traditional Chinese medicine. Alternative therapies, despite the term, should not be considered as an alternative to antiepileptic medication; they complement accepted drug treatment. Alternative therapies like yoga, through techniques that relax the body and mind, reduce stress, improve seizure control, and also improve quality of life. Ketogenic diet is a safe and effective treatment for intractable epilepsies; it has been recommended since 1921. The diet induces ketosis, which may control seizures. The most successful treatment of epilepsy is with modern antiepileptic drugs, which can achieve control of seizures in 70-80% cases. Patients opt for alternative therapies because they may be dissatisfied with antiepileptic drugs due to their unpleasant side effects, the long duration of treatment, failure to achieve control of seizures, cultural beliefs and, in the case of women, because they wish to get pregnant Surgical treatment may lead to physical and psychological sequelae and is an option only for a minority of patients. This article presents supportive evidence from randomized controlled trials done to assess the benefit of non-pharmacological treatment.

  10. Neuropeptides in epilepsy.

    Kovac, Stjepana; Walker, Matthew C

    2013-12-01

    Neuropeptides play an important role in modulating seizures and epilepsy. Unlike neurotransmitters which operate on a millisecond time-scale, neuropeptides have longer half lives; this leads to modulation of neuronal and network activity over prolonged periods, so contributing to setting the seizure threshold. Most neuropeptides are stored in large dense vesicles and co-localize with inhibitory interneurons. They are released upon high frequency stimulation making them attractive targets for modulation of seizures, during which high frequency discharges occur. Numerous neuropeptides have been implicated in epilepsy; one, ACTH, is already used in clinical practice to suppress seizures. Here, we concentrate on neuropeptides that have a direct effect on seizures, and for which therapeutic interventions are being developed. We have thus reviewed the abundant reports that support a role for neuropeptide Y (NPY), galanin, ghrelin, somatostatin and dynorphin in suppressing seizures and epileptogenesis, and for tachykinins having pro-epileptic effects. Most in vitro and in vivo studies are performed in hippocampal tissue in which receptor expression is usually high, making translation to other brain areas less clear. We highlight recent therapeutic strategies to treat epilepsy with neuropeptides, which are based on viral vector technology, and outline how such interventions need to be refined in order to address human disease.

    Full Text Available The study was based on the data of a sample of 400 epileptic patients (200 idiopathic and 200 symptomatic and 100 normal healthy individuals serving as controls. The PTC threshold distribution was bimodal. The number of non-tasters among idiopathic epileptics (35.5% and symptomatic epileptics (32.5% was significantly higher than controls (20%. The relative incidence of non-tasters in idiopathic and symptomatic epilepsies was 2.20 and 1.93 respectively. There is evidence that non-tasters tend to ingest a greater quantity of bitter tasting goitrogenic substances present naturally in edible plants which in turn exert greater thyroid stress in non-tasters or less sensitive tasters. Such a stress during intrauterine or early childhood growth and development might have affected neurological maturation which in turn made them more susceptible to epilepsy than tasters, who faced lesser stress.

In Japanese, "Moyamoya" means "hazy puff of smoke" and refers to the angiographic appearance of the abnormal network of vessels that develop at the base of the brain and basal ganglia to supply a collateral route of blood flow. We report here the case of Moyamoya disease in a 5 year-old girl with normal mentality with a one year history of epilepsy, with Todd's paralysis. This condition is rare and most patients are diagnosed in childhood.

    Full Text Available Introduction: The assessment of the problem of seizures requires knowledge of the clinical details and features of the seizures, the functional abnormality in the brain as shown on the EEG, and the structural assessment of the brain with an MRI study optimized for epilepsy. Usually MRI or computed tomographic (CT scan should be performed in evaluating the cause of a newly diagnosed seizure disorder. MRI is preferred over CT because of its greater sensitivity and specificity for identifying small lesions."nBecause there is an option of surgical excision of the "seizure focus," which may cure the patient, the detection of a focal abnormality of the brain is important for the formulation of the reason for the seizures and the options available for treatment. Knowledge of the brain abnormalities early in the course of treating the patient greatly helps the management of each individual. The challenge to epileptologists is that the problem of epilepsy is a special one, which requires optimized protocols dedicated to it."nMRI interpretation is different when used in a screening way and when viewed in the context of other investigations. This is particularly important when the patient has partial seizures and may be considered for surgical treatment."nMost centers that deal with epilepsy spend a great deal of time in ensuring the quality of their EEG and EEG interpretation. However, unless there is a radiologist with an interest in epilepsy or an epileptologist who spends time with radiologist colleagues, it can be difficult to establish good epilepsy-focused MRI with appropriate sequences, radiography, and interpretation. MRI acquisition and interpretation need to be focused on the problem of epilepsy."nIndication"nThe American academy of neurology has published practice parameters for neuroimaging (NI studies (MRI, CT of patients having a first seizure.

    Living with epilepsy in childhood has implications for the child and their family beyond the physical effects associated with epileptic seizures. Qualitative research has emerged, aiming to deliver a greater depth of understanding of the experiences of living with epilepsy from the perspectives of children with epilepsy, their parents, and their siblings. This review of qualitative research had three aims: first, to synthesize the demographic and epilepsy profiles of research participants in eligible studies in order to provide a clear picture of who are included and excluded when studying families' experiences; second, to present and discuss the methodological concerns and implications of research involving children with epilepsy; and third, to synthesize the findings arising from qualitative research with families in order to identify common themes across all relevant studies to date.

Twenty-one studies were identified as eligible for inclusion in the review. Findings in relation to the three aims were the following: 1) Researchers were seeking an understanding of children's experiences directly from children rather than by parental proxy.

    Living with epilepsy in childhood has implications for the child and their family beyond the physical effects associated with epileptic seizures. Qualitative research has emerged, aiming to deliver a greater depth of understanding of the experiences of living with epilepsy from the perspectives of children with epilepsy, their parents, and their siblings. This review of qualitative research had three aims: first, to synthesize the demographic and epilepsy profiles of research participants in eligible studies in order to provide a clear picture of who are included and excluded when studying families' experiences; second, to present and discuss the methodological concerns and implications of research involving children with epilepsy; and third, to synthesize the findings arising from qualitative research with families in order to identify common themes across all relevant studies to date.

    The concept or definition of epilepsy was mentioned as a chronic disease of the brain consisting of repetitions of EEG paroxysm and clinical seizures caused by excessive discharges of the cerebral neurons, in reference with Gastaut's opinion and the other statements. Further, we referred to diseases to be excluded from epilepsy such as isolated, occasional and subclinical seizures and so on. Next, new classifications of seizures and epilepsies were explained on the basis of revised terminology and concepts for organization of seizures and epilepsies in Report of the ILAE Communication in Classification and Terminology, 2005-09, in comparison with the Classification of Epileptic Seizures in 1981 and the Classification of Epilepsies and Epileptic Syndromes in 1989.

    The results of CT in 100 patients with acute hemiplegia in childhood are reported here. The etiology was various: 2 patients had infratentorial brain tumors, 56 had cerebral vascular diseases, 3 had head injuries, 16 had intracranial infectious diseases, one had postinfectious encephalomyelitis, one had multiple sclerosis, 2 had epilepsy, and the diagnosis of 19 were unknown. Eleven patients had a normal CT and a good prognosis. As for the type of onset, there were patients of type 1 with fever and 42 with convulsions and unconsciousness; those of type 2 with convulsions and unconsciousness were 12, and those of type 3 without fever and convulsions were 46. This classification is assumed to be useful, as the type of onset is characteristic of the etiology. Six patients were diagnosed correctly by repeated examinations, although the first CT did not reveal any remarkable findings. Capsular infarction, occlusion of the posterior cerebral artery in acute hemiplegia in childhood, abnormal findings of the internal capsule, thalamus, and midbrain in a patient with postinfectious encephalomyelitis, and a diffuse low density in the CT of the unilateral hemisphere in the patients with acute encephalopathy and acute hemiplegia of an obscure origin have been found after the introduction of computerized tomography.

    Full Text Available The epilepsy treatment is to be based on existing general principles and standards of therapy with differential approach to each patient. Besides peculiarities of treatment of different types of seizures and forms of epilepsy there are also differential approaches to special groups of patients. To one of such groups are referred to women of reproductive age. These patients are referred to special group of risk due to the development of certain side effects of antiepileptic drugs (АED. This article focuses in details on peculiarities of treatment of women of reproductive age with epilepsy with accent made on tolerability and safety of the antiepileptic therapy. It is necessary to take into consideration, that at women neuroendocrinal disorders can be caused both by the disease itself – epilepsy (in such case disorders depend on the starting age, form of epilepsy, focal localization, duration of disorder and other factors, referred to the disease, as well as by the undertaken therapy. The articlehereunder considers only issues, referred to the treatment, i. e. AED side effects and its input in the decrease of life quality of women with epilepsy. As women’s reproductive function starts forming long ago before childbearing age, it is necessary for this category to comprise not only women and adolescents, but girls as well. Notwithstanding the fact that so called benign forms of epilepsy pass before the pubescence period (idiopathic focal epilepsies, several forms of idiopathic generalized epilepsy, in many cases the epilepsy, which has started in childhood, continues in the adult age as well. In the same time there can be possible remote negative consequences of the antiepileptic therapy, which can show at a woman of a reproductive age. The data, given in the article, witnesses the need of the right AED selection at women of reproductive age, suffering from epilepsy. The AED should be selected not only depending on the form of the

    Full Text Available Objective: Epilepsy is a most common serious neurological disorder and is one of the world’s most prevalent non-communicable diseases. The aim of this study was to determine the prevalence and risk factors of epilepsy in 0–17 year old children in Trabzon, Turkey.Methods: A cross-sectional epidemiological investigation was performed in two phases, a screening phase and a confirmation of the diagnosis phase. The gold standard was a clinical investigation and neurological examination. The diagnosis of epilepsy followed clinical guidelines proposed by the International League against Epilepsy (ILAE. The chi-square test was used in analysis of the results and P-value <0.05 was calculated.Findings: The prevalence per 1000 participants of epilepsy was 8.6 (5.9–11.4; 95%CI. We detected 37 cases(18 males and 19 females of epilepsy. The male/female ratio was 0.95. This study showed an increased risk for epilepsy with low socioeconomic level, a history of postpartum seizure, meningitis, head trauma, febrile convulsion and family history of epilepsy. More than one seizure type was present in 15 (40.5% of epileptic children. Generalized tonic-clonic seizures were determined in 24 patients (64.9% and absence type in 9 (24.3%. It was found that 25.0% of children with epilepsy had never visited the school at the time the study was performed due to the disease and attendant seizures.Conclusion: The prevalence of epilepsy in Trabzon is low compared to other parts of Turkey and other developing countries.

    Full Text Available Introduction: Epilepsy is one of the most common neurological illnesses occurring in children. In approximately 20–30% of cases it is drug-resistant. Aim of the research: To assess the already-known risk factors, analyse the rarely described ones, and find new causes of epilepsy drug resistance in children, taking into account the level of impact of each factor. Material and methods : The study comprised 152 of all 383 children hospitalised in 2012 at the Neurology Department of the Polish Mother’s Memorial Hospital in Lodz due to epilepsy. Based on medical documentation, neurological examination, and our own questionnaire, we divided patients into two groups: drug-resistant epilepsy or drug-sensitive epilepsy. We compared the type, level of influence, and prevalence of different factors. For statistical analysis, the 2 test was used. Statistical significance was set at p < 0.05. Results: Drug-resistant epilepsy was found in 64 patients (42.1%, and drug-sensitive epilepsy was found in 88 patients (57.9%. Factors that were most probable to cause drug resistance included: high prevalence of seizures (Cramer’s V = 0.66, type of epileptic syndrome (V = 0.62, psychomotor developmental delay (V = 0.62, and occurrence of status epilepticus (V = 0.6. Factors such as infections of CNS in early childhood, repeated severe infections of airways in childhood, and mother’s infectious diseases with high fever during pregnancy were rare or non occurring (Cramer’s V = 0.41, 0.32, and 0.31, respectively. Conclusions : The study confirmed the previously known causes of drug resistance and indicated the significance of underestimated inflammatory and infectious factors involving pyrexia, in children and also in mothers during pregnancy.

    Full Text Available Psychiatrische Erkrankungen treten bei Epilepsiepatienten signifikant häufiger auf als in der Allgemeinbevölkerung und als bei Patienten mit anderen chronischen Erkrankungen. Die Depression stellt die häufigste psychiatrische Begleiterkrankung bei Epilepsie dar. Die Häufigkeit von Depressionen korreliert mit der Anfallskontrolle: Sie liegt zwischen 3 und 9 % bei gut kontrollierter Epilepsie, jedoch zwischen 20 und 55 % bei Patienten mit therapieresistenten Epilepsien. Umgekehrt ist bei Patienten mit neu diagnostizierten Epilepsien anamnestisch signifikant häufiger eine Depression zu erheben als in einem Vergleichskollektiv. Diese bidirektionale Beziehung zwischen Epilepsie und Depression könnte durch gemeinsame Pathomechanismen beider Erkrankungen erklärt werden. Obwohl das Vorliegen und der Schweregrad einer Depression die wichtigsten Prädiktoren für die Lebensqualität bei Epilepsiepatienten darstellen, werden Depressionen bei Epilepsiepatienten unterdiagnostiziert und unterbehandelt. Eine psychopharmakologische Behandlung sollte bei Vorliegen einer Begleitdepression deshalb unverzüglich initiiert werden, das epileptogene Potential von Antidepressiva stellt dabei ein vernachlässigbares Risiko dar. Die Prävalenz psychotischer Störungen bei Epilepsiepatienten liegt zwischen 2 und 8 %, wobei sogenannte episodische Psychosen (iktale, postiktale und Alternativpsychosen, die in einem zeitlichen Bezug zum Anfallsgeschehen stehen, und chronische Psychosen (interiktale Psychosen ohne zeitlichen Bezug zu den Anfällen, unterschieden werden können. Die Prävalenz von Angststörungen bei Epilepsiepatienten liegt zwischen 15 und 25 %. Man kann zwischen präiktaler, iktaler, postiktaler und interiktaler Angst unterscheiden.

    Epilepsy is surgically curable if the seizure focus can be localized and does not include areas of eloquent cortex. Because epileptic cells are indistinct from surrounding brain, resection typically includes normal tissue. Using the rat kindling model of epilepsy, we evaluated Photodynamic Therapy (PDT) as a super-selective lesioning technique. We present a series of pilot studies to evaluate: 1) Protoporphyrin IX (PpIX) fluorescence, 2) the efficacy of PDT to raise seizure thresholds, 3) the safety of PDT using behavioral studies, and 4) histologic results. Bipolar electrodes were chronically implanted into the cortex and animals received successive low-level stimulation generating seizures of increasing severity. Following 5-aminolevulinic acid (ALA) administration, fully kindled rats received electrical stimulation to induce a generalized seizure. Animals were irradiated with laser light focused onto a temporal craniectomy. Our results show: 1) an increase in PpIX fluorescence in the seizure group, 2) PDT treated animals failed to demonstrate seizure activity following repeat stimulation, 3) no statistically significant difference between treated and control animals were observed on behavioral tests, 4) histology showed pyknotic hippocampal pyramidal cells in the CA3 region without areas of obvious necrosis. In conclusion, this is the first report of heightened PpIX-mediated fluorescence in epileptic brain. The selective accumulation of PpIX with laser PDT may provide a less invasive and more precise technique for obliteration of epileptic foci. PDT warrants additional research to determine if this technique may augment or replace existing procedures for the surgical management of epilepsy.

A higher trait-anxiety score (chronic anxiety than that of controls was found for the epileptic group. For the epileptic group higher levels of the A-trait occurred in patients with EEG abnormalities with left temporal localization. We have also observed that the shorter the epilepsy lasts (less than two years, the higher the trait-anxiety levels. Convulsions and awareness loss during epileptic seizures do not modify state and trait-anxiety scores.

    Epilepsy is one of the most frequent neurological disorders, both in children and adult persons. About 0.5-1% of general population suffer from epilepsy, which means that about 50 million people in the world are affected. First years of life and very late adulthood are periods in human's life particularly predisposing to epilepsy. Repetitive epileptic seizures may cause many life-threatening situations and significantly lower patient's quality of life. To the most serious complications belong status epilepticus and sudden unexpected deaths due to epilepsy (SUDEP). Absences from work or school caused by seizures, difficulties in social life, frequent injuries and necessity of polytherapy are also important for patients. All these factors result in low self-esteem and poor quality of life. The main aim of the treatment was control of epileptic seizures. However, despite of new antiepileptic drugs developed almost every year, in one third of all patients with epilepsy seizures remain out of control. Those patients are regarded to have "drug-resistant epilepsy". Despite of significant scale of the problem, there is no one definition of the phenomenon. In the presented review the authors outline current definitions, recent opinions on pathogenesis and risk factors, and provide practical rules of pharmacotherapy of epilepsy, which should help to restrict drug-resistancy.

    Full Text Available Benign childhood epilepsy with centro-temporal spikes (BECTS is a form of epilepsy with no demonstrable anatomical lesion showing spontaneous seizure remission. During the active phase of the disease the children may show cognitive deficits. The objective of this study was to assess, in children with BECTS, the relationship between clinical-EEG aspects and performance in the school performance test (SPT, Raven's progressive matrixes test and the Wechsler Intelligence Scale for Children (WISC-III. Forty-two 7 to 11 year old children were included and the following tests carried out: anamnesis, neurological examination, electroencephalogram (EEG, SPT, Raven's test and WISC-III. The children with BECTS had normal IQ values but showed inferior performance in the SPT more frequently than "healthy" children, paired with respect to age and maternal scholastic level. There was moderate positive correlation between WISC-III results and the age when the seizures started and the educational level of the parents. On the other hand, aspects linked to the epileptic nature of BECTS, such as the number of seizures, time since last seizure and the number and lateralization of the centro-temporal spikes on the EEG, showed no correlation with the neuropsychological tests.A epilepsia benigna da infância com pontas centrotemporais (EBICT é uma forma de epilepsia na qual não existem lesões anatômicas demonstráveis e há remissão espontânea das crises.

    Epilepsy care in Ireland is shared between primary, secondary and tertiary care services with the General Practitioner (GP) managing the process. Barriers to effective epilepsy care in Irish general practice remain undocumented although sub-optimal and fragmented services are frequently anecdotally reported. This survey of Irish GPs reports on such barriers to epilepsy care and on the Information & Communication Technology (ICT) issues potentially relevant to the use of an epilepsy specific Electronic Patient Record (EPR). The response rate was 247\\/700 (35.3%). Respondents supported the concept of shared care for epilepsy 237 (96%) however they were very dissatisfied with existing neurology services, including pathways of referral 207 (84%) and access to specialist neurology advice and investigations 232 (94%). They reported that neurology services and investigations may be accessed more expeditiously by patients with private health insurance than those without 178 (72%). Consequently many patients are referred to the emergency department for assessment and treatment 180 (73%). A deficit in epilepsy care expertise among GPs was acknowledged 86 (35%). While computerisation of GP practices appears widespread 230 (93%), just over half the respondents utilise available electronic functionalities specific to chronic disease management. GP specific electronic systems infrequently link or communicate with external electronic sources 133 (54%). While the current pathways of care for epilepsy in Ireland appear fragmented and inadequate, further investigations to determine the quality and cost effectiveness of the current service are required.

  20. Genetic Causes of Generalized Epilepsies.

    2015-06-01

    Generalized epilepsies, particularly the idiopathic or genetic generalized epilepsies (GGEs), represent some of the most common epilepsies. Clinical genetic data including family studies and twin studies provide compelling evidence for a prominent genetic impact. The first decade of the 21st century was marked by progress in understanding the basic biology of generalized epilepsies including generalized/genetic epilepsies with febrile seizures plus (GEFS+) and GGE through studies of large families, discovering causative mutations in SCN1A, SCN1B, GABRG2, and GABRA1. Subsequently, recurrent microdeletions at 15q13.3, 16p13.11, and 15q11.2 were found to be relevant risk factors for nonfamilial GGE. Genes for epileptic encephalopathies such as SLC2A1 were rediscovered in GGE, highlighting the biological continuum between different epilepsies. Genome-wide studies examining common genetic risk factors identified common variants in SCN1A, indicating a convergence of shared pathophysiological pathways in various types of epilepsies. In the era of next-generation sequencing, however, the GGEs appear more complex than expected, and small or moderately sized studies give only a limited genetic perspective. Thus, there is a strong impetus for large collaborative investigations on an international level. PMID:26060908

    Full Text Available Brain perfusion changes during seizures were first observed in the 1930s. Single Photon Emission Computed Tomography (SPECT was developed in the 1970s, and tracers suitable for the imaging of regional cerebral perfusion (rCP became available in the 1980s. The method was first used to study rCP in the interictal phase, and this showed areas of low perfusion in a proportion of cases, mainly in patients with temporal lobe epilepsies. However, the trapping paradigm of tracers such as hexamethyl propyleneamine oxime (HMPAO provided a practicable method of studying changes in rCP during seizures, and a literature was established in the late 1980s and early 1990s showing a typical sequence of changes during and after seizures of mesial temporal lobe origin; the ictal phase was associated with large increases in perfusion throughout the temporal lobe, with first the lateral, then the mesial temporal lobe becoming hypoperfused in the postictal phase. Activation and inhibition of other structures, such as the basal ganglia and frontal cortex, were also seen. Studies of seizures originating elsewhere in the brain have shown a variety of patterns of change, according to the structures involved. These changes have been used practically to aid the process of localisation of the epileptogenic zone so that epilepsy surgery can be planned.

    This article reviews research on the use of diet, nutritional supplements, and hormones in the treatment of epilepsy. Potentially beneficial dietary interventions include identifying and treating blood glucose dysregulation, identifying and avoiding allergenic foods, and avoiding suspected triggering agents such as alcohol, aspartame, and monosodium glutamate. The ketogenic diet may be considered for severe, treatment-resistant cases. The Atkins diet (very low in carbohydrates) is a less restrictive type of ketogenic diet that may be effective in some cases. Nutrients that may reduce seizure frequency include vitamin B6, magnesium, vitamin E, manganese, taurine, dimethylglycine, and omega-3 fatty acids. Administration of thiamine may improve cognitive function in patients with epilepsy. Supplementation with folic acid, vitamin B6, biotin, vitamin D, and L-carnitine may be needed to prevent or treat deficiencies resulting from the use of anticonvulsant drugs. Vitamin K1 has been recommended near the end of pregnancy for women taking anticonvulsants. Melatonin may reduce seizure frequency in some cases, and progesterone may be useful for women with cyclic exacerbations of seizures. In most cases, nutritional therapy is not a substitute for anticonvulsant medications. However, in selected cases, depending on the effectiveness of the interventions, dosage reductions or discontinuation of medications may be possible.

  3. Radiological diagnosis in epilepsy

    International Nuclear Information System (INIS)

    Results: Hippocampal sclerosis, the most frequent cause of focal epilepsy, can be detected with 90-98% sensitivity by visual analysis and quantitative signal and volume measurement of the hippocampi in high-resolution coronal T2-weighted MR images. Benign tumors, such as gangliogliomas and dysembryoplastic neuoepithelial tumors (DNT), as well as cortical dysplasias are frequently composed of cystic and solid parts, which may show calcification, but never edema. Bloodbrain-barrier disruption as seen in approximately 40% of the benign tumors are the only feature that allows to differentiate them from non-neoplastic dysplasias. In rare cases of totally calcified lesions, CT may be the only diagnostic imaging modality. Proton-density-weighted or FLAIR imaging is essential for the detection of small solid cortical lesion components, because they provide sufficient contrast with adjacent CSF. T1-weighted inversion recovery images are most sensitive for the detection of migration and gyration abnormalities. The depiction of calcified lesions and hemosiderin deposits after trauma is most efficient with T2* weighted gradient echo sequences. Conclusions: With further rapid improvent of high resolution MRI techniques, the near future will probably show that nearly 100% of focal epilepsies are caused by structural brain abnormalities. With refined imaging techniques applied, the sensitivity of neuroradiological evaluation is 90% at present. Therefore presurgical MRI plays a key role in epilespy surgery. (orig.)

    Winawer, Melodie R

    2006-05-01

    Phenotype definition consists of the use of epidemiologic, biological, molecular, or computational methods to systematically select features of a disorder that might result from distinct genetic influences. By carefully defining the target phenotype, or dividing the sample by phenotypic characteristics, we can hope to narrow the range of genes that influence risk for the trait in the study population, thereby increasing the likelihood of finding them. In this article, fundamental issues that arise in phenotyping in epilepsy and other disorders are reviewed, and factors complicating genotype-phenotype correlation are discussed. Methods of data collection, analysis, and interpretation are addressed, focusing on epidemiologic studies. With this foundation in place, the epilepsy subtypes and clinical features that appear to have a genetic basis are described, and the epidemiologic studies that have provided evidence for the heritability of these phenotypic characteristics, supporting their use in future genetic investigations, are reviewed. Finally, several molecular approaches to phenotype definition are discussed, in which the molecular defect, rather than the clinical phenotype, is used as a starting point.

    Full Text Available There are close to one and half million women with epilepsy (WWE in reproductive age group in India. WWE have several unique gender-specific problems in the biological and social domains. Women experience more social stigma from epilepsy and have more difficulty with education and employment. They have more difficulty to get married and sustain successful family life. Reproductive hormones like estrogen and progesterone have opposing effect on seizure threshold. WWE have increased risk of infertility. About 10% of their babies may have major congenital malformations. Most of the adverse biological outcomes for WWE are related to adverse effects of antiepileptic drugs (AEDs. Traditional AEDs like phenobarbitone and sodium valproate are probably associated with increased risk of fetal malformations or other adverse fetal outcomes. Polytherapy and use of high dose of any AED is associated with higher risk fetal complications. It is very important that all WWE have a preconception evaluation done by a neurologist, when the need to continue AEDs or possibility of reducing AED load could be assessed. All WWE need to take folic acid 5 mg daily during preconception period and pregnancy. They should undergo a detailed screening for fetal malformations between 12 and 18 weeks of pregnancy. The neurologist, gynecologist, imageologist and pediatrician need to work as a team while managing pregnancy in WWE. It is important to reassure WWE and their relatives that pregnancy is safe in WWE and their children are healthy in more than 90% instances.

Potentially beneficial dietary interventions include identifying and treating blood glucose dysregulation, identifying and avoiding allergenic foods, and avoiding suspected triggering agents such as alcohol, aspartame, and monosodium glutamate. The ketogenic diet may be considered for severe, treatment-resistant cases. The Atkins diet (very low in carbohydrates) is a less restrictive type of ketogenic diet that may be effective in some cases. Nutrients that may reduce seizure frequency include vitamin B6, magnesium, vitamin E, manganese, taurine, dimethylglycine, and omega-3 fatty acids. Administration of thiamine may improve cognitive function in patients with epilepsy. Supplementation with folic acid, vitamin B6, biotin, vitamin D, and L-carnitine may be needed to prevent or treat deficiencies resulting from the use of anticonvulsant drugs. Vitamin K1 has been recommended near the end of pregnancy for women taking anticonvulsants. Melatonin may reduce seizure frequency in some cases, and progesterone may be useful for women with cyclic exacerbations of seizures. In most cases, nutritional therapy is not a substitute for anticonvulsant medications. However, in selected cases, depending on the effectiveness of the interventions, dosage reductions or discontinuation of medications may be possible. PMID:17397265

  7. Modern management of juvenile myoclonic epilepsy.

    2016-06-01

    Juvenile myoclonic epilepsy (JME) is a common genetic epilepsy syndrome usually presenting in adolescence and characterized by myoclonic jerks, predominately in the arms, associated with tonic-clonic seizures and less often generalized absences. Although the evidence base for treating JME is weak, most experts regard sodium valproate as drug of first choice. The recent diktat from the European regulatory agency - recommending that sodium valproate should not be prescribed to female children, adolescents or women of childbearing potential unless other treatments were ineffective or not tolerated - has substantially changed the way JME is being managed in this population. This paper reviews the literature underpinning the pharmacological treatment of JME. Data reporting associated symptoms of frontal lobe dysfunction in some patients with JME are discussed, as is the importance of counselling on lifestyle issues as an essential component of management. Long-term studies examining pharmacological and quality-of-life outcomes are reviewed, indicating a range of different phenotypes and likely genotypes underpinning this fascinating disorder. Lastly, a practical approach to managing JME in young men and women is summarized. PMID:27082040

    Glutathione-S-transferases enzymes are involved in the detoxification of several endogenous and exogenous substances. In this present study, we evaluated the effects of two glutathione-S-transferase polymorphisms, (GSTM1 and GSTT1) on epilepsy risk susceptibility in a Tunisian population. These polymorphisms were analyzed in 229 healthy subjects and 98 patients with epilepsy, using a polymerase chain reaction (PCR). Odds ratio (ORs) was used for analyzing results. The study results demonstrated that individuals with the GSTM1 null genotype were at an increased risk of developing epilepsy [OR=3.80, 95% confidence interval (CI) (2.15-4.78)], whereas no significant effects were observed between individuals with GSTT1 null genotype and epilepsy risk [OR=1.15, 95% CI (0.62-2.12)]. These genotyping finding revealed that the absence of GSTM1 activity could be contributor factor for the development of epilepsy disease.

  10. Uncovering genomic causes of co-morbidity in epilepsy: gene-driven phenotypic characterization of rare microdeletions.

    Directory of Open Access Journals (Sweden)

    Dalia Kasperavičiūtė

    Full Text Available BACKGROUND: Patients with epilepsy often suffer from other important conditions. The existence of such co-morbidities is frequently not recognized and their relationship with epilepsy usually remains unexplained. METHODOLOGY/PRINCIPAL FINDINGS: We describe three patients with common, sporadic, non-syndromic epilepsies in whom large genomic microdeletions were found during a study of genetic susceptibility to epilepsy. We performed detailed gene-driven clinical investigations in each patient. Disruption of the function of genes in the deleted regions can explain co-morbidities in these patients. CONCLUSIONS/SIGNIFICANCE: Co-morbidities in patients with epilepsy can be part of a genomic abnormality even in the absence of (known congenital malformations or intellectual disabilities. Gene-driven phenotype examination can also reveal clinically significant unsuspected condition.

    To improve the well-being of adolescents with epilepsy, research is needed on how adolescents cope. In this study, Lazarus' model of stress and coping and Antonovsky's Theory of Sense of Coherence were used as the theoretical framework. The aim was to describe the lived experience of adolescents with epilepsy and their coping skills. The participants were 13-19 years old with an epilepsy diagnosis but without mental retardation or cerebral palsy. The study was performed in southern Sweden at the pediatric department of a university hospital. Semistructured and open-ended interviews were conducted with 13 adolescents. The transcripts were analyzed with manifest and latent content analysis. All the adolescents had developed strategies to cope with the emotional strains caused by epilepsy. They experienced strains from the seizures, limitation of leisure activities, side effects of medication, and feelings of being different. The coping strategies described were finding support, being in control, and experimenting.

    Problems of systematization of remissions of epileptic seizures and epilepsy are discussed on the basis of clinical examination of 341 epileptic patients with seizures suppressed for many years and international classifications of epilepsy. A classification, developed by the authors, is presented. It reflects stages of regress of the disease in achievement of prolonged (for years) control of seizures. The possibility of drug dependence development in these therapeutic remissions is also taken into consideration.

  16. Epilepsy in Dante's poetry.

    Science.gov (United States)

    Mula, Marco

    2016-04-01

    Dante Alighieri is the greatest Italian poet and one of the most important writers in Western literature. He is best known for the epic poem "Commedia", later named "La Divina Commedia" that has profoundly influenced not only poetic imagination but also all subsequent allegorical creations of imaginary worlds in literature. This paper examines the poetic description of some episodes of loss of consciousness in Dante's poetry discussing how and why typical elements of epileptic seizures have been used. On the 750th anniversary of Dante's birth, his poetry still remains to be an inspiring source of debate and reflection. This article is part of a Special Issue entitled "Epilepsy, Art, and Creativity". PMID:26907926

  17. Imaging of intractable paediatric epilepsy

    Sanjay Prabhu

    2015-10-01

    Full Text Available Approximately 20% of paediatric patients with epilepsy are refractory to medical therapies. In this subgroup of patients, neuroimaging plays an important role in identifying an epileptogenic focus. Successful identification of a structural lesion results in a better outcome following epilepsy surgery. Advances in imaging technologies, methods of epileptogenic region localisation and refinement of clinical evaluation of this group of patients in epilepsy centres have helped to widen the spectrum of children who could potentially benefit from surgical treatment. In this review, we discuss ways to optimise imaging techniques, list typical imaging features of common pathologies that can cause epilepsy, and potential pitfalls to be aware of whilst reviewing imaging studies in this challenging group of patients. The importance of multidisciplinary meetings to analyse and synthesise all the non-invasive data is emphasised. Our objectives are: to describe the four phases of evaluation of children with drug-resistant localisation-related epilepsy; to describe optimal imaging techniques that can help maximise detection of epileptogenic foci; to describe a systematic approach to reviewing magnetic resonance imaging of children with intractable epilepsy; to describe the features of common epileptogenic substrates; to list potential pitfalls whilst reviewing imaging studies in these patients; and to highlight the value of multimodality and interdisciplinary approaches to the management of this group of children.

    2014-01-01

    Evidence of Absence software (EoA) is a user-friendly application used for estimating bird and bat fatalities at wind farms and designing search protocols. The software is particularly useful in addressing whether the number of fatalities has exceeded a given threshold and what search parameters are needed to give assurance that thresholds were not exceeded. The software is applicable even when zero carcasses have been found in searches. Depending on the effectiveness of the searches, such an absence of evidence of mortality may or may not be strong evidence that few fatalities occurred. Under a search protocol in which carcasses are detected with nearly 100 percent certainty, finding zero carcasses would be convincing evidence that overall mortality rate was near zero. By contrast, with a less effective search protocol with low probability of detecting a carcass, finding zero carcasses does not rule out the possibility that large numbers of animals were killed but not detected in the searches. EoA uses information about the search process and scavenging rates to estimate detection probabilities to determine a maximum credible number of fatalities, even when zero or few carcasses are observed.

  3. Injuries in epilepsy: a review of its prevalence, risk factors, type of injuries and prevention

    Directory of Open Access Journals (Sweden)

    Jose Tellez-Zenteno

    2009-12-01

    Full Text Available Currently, there is intense clinical research into various aspects of the medical risks relating to epilepsy, including total and cause-specific mortality, accidents and injuries in patients with epilepsy and mortality related with seizures. Seizures occurring in precarious situations and resulting in injuries are still an important concern for patients with epilepsy, their employers and their caregivers. Submersion injuries, motor vehicle accidents, burns, and head injuries are among the most feared epilepsy-related injuries. These concerns seem valid because the hallmark of epilepsy, episodic impairment of consciousness and motor control, may occur during interictal EEG epileptiform discharges, even in the absence of a clinical seizure. In addition, psychomotor comorbidity and side effects of antiepileptic drugs may contribute to the risk of injuries in patients with epilepsy. Published risk factors for injuries include the number of antiepileptic drugs, history of generalized seizures, and seizure frequency. In general, epidemiological information about incidence of injuries has been conflicting and sparse. In general, studies focusing on populations with more severe forms of epilepsy tend to report substantially higher risks of injuries than those involving less selected populations. On the other hand, studies based on non-selected populations of people with epilepsy have not shown an increased frequency of injuries in people with epilepsy compared with the general population. Some studies have shown that patients with epilepsy are more frequently admitted to the hospital following an injury. Possible explanations include: more cautious attitude of clinicians toward injuries occurring in the setting of seizures; hospitalization required because of seizures and not to the injuries themselves; and hospitalization driven by other issues, such as comorbidities, which are highly prevalent in patients with epilepsy. Potentially the high rate of

    Childhood ischemic strokes can lead to problems like hemiplegias, epilepsies, cognitive changes (memory and mathematical solutions), and language ability (reading, writing, and aphasias). The purpose of this study was to evaluate language and its aspects in children with unilateral ischemic stroke and associate them with the age during the event, injured side, and occurrence of epilepsy. Thirty-two children between 8 months and 19 years of age were evaluated. Among them, 21 (65%) had a change in their language skills, there being a connection between age and the time of injury (P < .05). The most impaired aspects were their phonology, semantics, and syntax. In this sample, there was a persistent change in the semantic aspect, which is an alert for the early detection of learning and future development problems.

    Chromodomain helicase DNA-binding protein 2 (CHD2) gene mutations have been reported in patients with myoclonic-atonic epilepsy (MAE), as well as in patients with Lennox-Gastaut, Dravet, and Jeavons syndromes and other epileptic encephalopathies featuring generalized epilepsy and intellectual disability. The aim of this study was to assess the impact of CHD2 mutations in a series of patients with MAE. Twenty patients affected by MAE were included in the study. We analyzed antecedents, age at onset, seizure semiology and frequency, EEG, treatment, and neuropsychological outcome. We sequenced the CHD2 gene with Sanger technology. We identified a CHD2 frameshift mutation in one patient (c.4256del19). He was a 17-year-old boy with no familial history for epilepsy and normal development before epilepsy onset. Epilepsy onset was at 3years and 5months: he presented with myoclonic-atonic seizures, head drops, myoclonic jerks, and absences. Interictal EEGs revealed slow background activity associated with generalized epileptiform abnormalities and photoparoxysmal response. His seizures were highly responsive to valproic acid, and an attempt to withdraw it led to seizure recurrence. Neuropsychological evaluation revealed moderate intellectual disability. Chromodomain-helicase-DNA-binding protein 2 is not the major gene associated with MAE. Conversely, CHD2 could be responsible for a proper phenotype characterized by infantile-onset generalized epilepsy, intellectual disability, and photosensitivity, which might overlap with MAE, Lennox-Gastaut, Dravet, and Jeavons syndromes.

  10. Increased expression of Notch1 in temporal lobe epilepsy:animal models and clinical evidence

    Temporal lobe epilepsy is associated with astrogliosis. Notch1 signaling can induce astrogliosis in glioma. However, it remains unknown whether Notch1 signaling is involved in the pathogenesis of epilepsy. This study investigated the presence of Notch1, hairy and enhancer of split-1, and glial fibrillary acidic protein in the temporal neocortex and hippocampus of lithium-pilocar-pine-treated rats. The presence of Notch1 and hairy and enhancer of split-1 was also explored in brain tissues of patients with intractable temporal lobe epilepsy. Quantitative electroencephalo-gram analysis and behavioral observations were used as auxiliary measures. Results revealed that the presence of Notch1, hairy and enhancer of split-1, and glial ifbrillary acidic protein were en-hanced in status epilepticus and vehicle-treated spontaneous recurrent seizures rats, but remain unchanged in the following groups:control, absence of either status epilepticus or spontaneous recurrent seizures, and zileuton-treated spontaneous recurrent seizures. Compared with patient control cases, the presences of Notch1 and hairy and enhancer of split-1 were upregulated in the temporal neocortex of patients with intractable temporal lobe epilepsy. Therefore, these results suggest that Notch1 signaling may play an important role in the onset of temporal lobe epilepsy via astrogliosis. Furthermore, zileuton may be a potential therapeutic strategy for temporal lobe epilepsy by blocking Notch1 signaling.

    A previous study has suggested that epilepsy is commoner in prisons than in the general population. We devised a standard definition of "epilepsy" and then interviewed a representative sample of the "epileptics" in prisons. The results confirmed the initial conclusion, and showed the point prevalence of epilepsy in prison and Borstals to be at least 7.1/1,000 men. PMID:5386266

    The concept of symptomatic epilepsy and the difficulties in assigning cause in epilepsy are described. A historical review is given, emphasizing aspects of the history which are relevant today. The historical review is divided into three approximately semicentenial periods (1860-1910, 1910-1960, 1960-present). A definition of symptomatic epilepsy and this is followed by listing of causes of symptomatic epilepsy. The fact that not all the causes of idiopathic epilepsy are genetic is discussed. A category of provoked epilepsy is proposed. The complexities in assigning cause include the following: the multifactorial nature of epilepsy, the distinction between remote and proximate causes, the role of nongenetic factors in idiopathic epilepsy, the role of investigation in determining the range of causes, the fact that not all symptomatic epilepsy is acquired, the nosological position of provoked epilepsy and the view of epilepsy as a process, and the differentiation of new-onset and established epilepsy. The newly proposed ILAE classification of epilepsy and its changes in terminologies and the difficulties in the concept of acute symptomatic epilepsy are discussed, including the inconsistencies and gray areas and the distinction between idiopathic, symptomatic, and provoked epilepsies. Points to be considered in future work are listed.

    The aetiology and outcome of dogs with juvenile-onset seizures were investigated. One hundred and thirty-six dogs whose first seizure occurred before the age of one year were investigated. One hundred and two dogs were diagnosed with idiopathic epilepsy (IE), 23 with symptomatic epilepsy (SE), nine with reactive seizures (RS) and two with probable symptomatic epilepsy (pSE). The outcome was known in 114 dogs; 37 per cent died or were euthanased as a consequence of seizures. The mean survival time of this population of dogs was 7.1 years. Factors that were significantly associated with survival outcome included the diagnosis of SE and the number of antiepileptic drugs (AEDs) used before investigation. The use of one AED before investigation and a diagnosis of SE were associated with a negative outcome, whereas receiving no AED medications before referral was associated with a longer survival. For dogs with IE, survival time was shortened if the dog was a border collie or with a history of status epilepticus;receiving no AEDs before referral in the IE group was associated with a positive outcome. Seizure-free status was achieved in 22 per cent of dogs diagnosed with IE. While the survival times were longer than previously reported in canine epilepsy, similar remission rates to those reported in childhood epilepsy, where a 70 per cent remission rate is documented, were not seen in the canine juvenile population.

This article reviews the indications, the various surgical options available and the outcome of surgery for drug resistant epilepsy based on current evidence. Epilepsy surgery is a well-established option for patients who have been diagnosed to have drug resistant epilepsy (DRE (on at least two appropriate, adequate anti-epileptic drugs (AEDs (either in monotherapy or in combination with continuing seizures, where the presurgical work-up has shown concordance of structural imaging (magnetic resonance imaging and electrical mapping data (electroencephalography (EEG, video EEG. There may be a requirement of functional imaging techniques in a certain number of DRE like positron emission tomography (PET, single photon emission tomography, (SPECT. Invasive monitoring should be restricted to a few when all noninvasive investigations are inconclusive, there is a dual pathology or there is a discordance of noninvasive data. The types of surgery could be curative (resective surgeries: amygdalo hippocampectomy, lesionectomy and multilobar resections; functional surgeries: hemispherotomy and palliative (multiple subpial transaction, corpus callosotomy, vagal nerve stimulation. Epilepsy surgery in indicated cases has a success range from 50 to 86% in achieving seizure freedom as compared with < 5% success rate with AEDs only in persons with DRE. Centers performing surgery should be categorized into Level I and Level II.

    While genetic causes of epilepsy have been hypothesized from the time of Hippocrates, the advent of new genetic technologies has played a tremendous role in elucidating a growing number of specific genetic causes for the epilepsies. This progress has contributed vastly to our recognition of the epilepsies as a diverse group of disorders, the genetic mechanisms of which are heterogeneous. Genotype-phenotype correlation, however, is not always clear. Nonetheless, the developments in genetic diagnosis raise the promise of a future of personalized medicine. Multiple genetic tests are now available, but there is no one test for all possible genetic mutations, and the balance between cost and benefit must be weighed. A genetic diagnosis, however, can provide valuable information regarding comorbidities, prognosis, and even treatment, as well as allow for genetic counseling. In this review, we will discuss the genetic mechanisms of the epilepsies as well as the specifics of particular genetic epilepsy syndromes. We will include an overview of the available genetic testing methods, the application of clinical knowledge into the selection of genetic testing, genotype-phenotype correlations of epileptic disorders, and therapeutic advances as well as a discussion of the importance of genetic counseling.

    Alzheimer’s disease (AD) and epilepsy are separated in the medical community, but seizures occur in some patients with AD, and AD is a risk factor for epilepsy. Furthermore, memory impairment is common in patients with epilepsy. The relationship between AD and epilepsy remains an important question because ideas for therapeutic approaches could be shared between AD and epilepsy research laboratories if AD and epilepsy were related. Here we focus on one of the many types of epilepsy, temporal ...

  20. Brain SPECT in childhood

    International Nuclear Information System (INIS)

    The modalities and the indications of perfusion and neurotransmission SPECT in childhood are presented. The perfusion as well as neurotransmission tracers have not yet authorization for use in children; they have to be used by prescription of magistral preparation or in research protocols. The radioprotection rules have to be strictly respected. The most frequent indication of perfusion SPECT is pharmacologically resistant epilepsy; the ictal SPECT before surgery allows the localization of the epileptogenic focus. Other indications are relevant in the prognosis of neonatal anoxia and encephalitis. In psychiatric disorders, especially in autism, the interest is the physiopathological approach of the brain dysfunctions. The neurotransmission SPECT is emerging as a consequence of the development of new radiotracer, as the dopaminergic system ligands. The decrease of the dopamine D2 receptors in the striatum can be imaged and quantified in the neonate. The lesions of dopamine system seem to be a consequence of the neonatal hypoxia-ischemia and it is predictive of motor sequelae. Brain SPECT should become a routine examination in child neurologic and psychiatric disorders. (authors)

  1. Epilepsy and driving

    Full Text Available Epilepsy is a disease with high prevalence, which interferes driving and may lead to car accident; This case-control study has been done on 100 epileptic patients and 100 persons as control group, who had history of driving. We gathered our patients with face to face interview and registering their information in special forms which were prepared for this study. There were three times more accidents among epileptic cases comparing with control group and this difference was more considerable in men and in patients under 35 years old. The cause of accident were not seizure attack in more than 60% of the patients and these ordinary accidents were also more in case group. Epileptic patients with history of car accidents during driving had poor drug compliance comparing with the epileptics without history of an accident so drug compliance may be valuable in predicting accident in these patients. We have also found poor drug compliance in whom seizure attacks caused accident for them. 58% of the epileptics had not consulted their physician about driving. 43.3% of seizures during driving were of generalized type and none of the patients had inform police about their disease during getting driving license.

    Toxoplasma gondii is a zoonotic parasite can be seen in all the vital organ; in the acute phase, it can be found in the blood, cerebrospinal fluid, semen, tears, saliva, urine, and in almost all body fluids. Transplasental infection can lead to fetal damage and miscarriage. Its last hosts are felines and intermediate hosts are all mammals, including humans. People infected by the ingestion of meat containing cysts in undercooked or raw, are thrown oocysts with cat felines By taking in water and food, from mother to fetus transplacental way, the infected organ transplantation, blood transfusion, laboratory accidents and kaprofaj transmitted by mechanical vectors of the invertebrates. Suppression of the immune system is being transformed to the shape and texture of the cysts with bradyzoite. The parasite settles in the cells of the tissue cysts and causes change in the cellular mechanisms, such as cytokinin task. Depending on changes and type of neurotransmitter (GABA, glutamate, serotonin, dopamine) levels in CSF in ions (Ca, K, Cl, Mg), it is believed that there is a change in their concentration. In this review, literature about the relationship between T. gondii and epilepsy and epileptiform activity the importance of parasites, which settle in the brain, will be highlighted. PMID:27594290

  3. Photosensitivity and epilepsy.

    2004-08-01

    Photosensitive epilepsy is a well-known condition characterized by seizures in patients who show photoparoxysmal responses on electroencephalography (EEG) elicited by intermittent photic stimulation. Photoparoxysmal responses can be defined as epileptiform EEG responses to intermittent photic stimulation or to other visual stimuli of everyday life and are frequently found in nonepileptic children. The modern technologic environment has led to a dramatic increase in exposure to potential trigger stimuli; nowadays, television and video games are among the most common triggers in daily life. There is ample evidence for genetic transmission of photoparoxysmal responses; systematic family studies have provided data for an autosomal dominant mode of inheritance with age-dependent penetrance for photosensitivity. The age of maximum penetrance is between 5 and 15 years. The prognosis for control of seizures induced by visual stimulation is generally very good. The large majority of patients do not need anticonvulsant therapy, but, when needed, the drug of choice is valproate. Stimulus avoidance and stimulus modification can be an effective treatment in some patients and can sometimes be combined with antiepileptic drug treatment. PMID:15605465

  4. Epilepsy and metaphors in literature.

    Science.gov (United States)

    Wolf, Peter

    2016-04-01

    This topic has two different aspects: seizures and epilepsy used as metaphors and seizures described in metaphors. Whereas some metaphors are unique and have high literary value, others can be categorized in prototypical groups. These include sexual metaphors; metaphors of strong emotions, of life crises and breakdown, and also of exultation; religious metaphors; and metaphors of weakness which mostly belong to older literature. Writers with epilepsy, in their literary texts, rarely talk about seizures in metaphors. Authors who do this sometimes seem to use reports that they have received from afflicted persons. The most common metaphors for seizures belong to the realms of dreams and of strong sensory impressions (visual, auditory). More rarely, storm and whirlwind are used as literary metaphors for seizures. This article is part of a Special Issue entitled "Epilepsy, Art, and Creativity".

    Introduccion. Los conocimientos que la neurociencia basica y el neurometabolismo estan aportando en epilepsia pediatrica, y en concreto en mecanismos de comunicacion sinaptica, crecen rapidamente. Existe, no obstante, una desconexion entre estos avances y una vision que los integre de manera global y en la practica clinica y terapeutica. Objetivos. Ofrecer una vision integradora de los diferentes mecanismos moleculares y metabolicos que se conocen y postulan en epilepsia pediatrica, y sugerir conceptos como el de 'metabolismo sinaptico' y 'fenotipos sinapticos' como herramientas utiles para desarrollar este enfoque. Desarrollo. Se revisan los estudios mas destacados que intentan explicar las caracteristicas esenciales de la comunicacion sinaptica en el cerebro en desarrollo, a traves de diferentes moleculas, basicamente proteinas sinapticas, canales ionicos (cotransportadores de cloro, sodio y potasio), la compartimentalizacion pre y postsinaptica, y los principales actores metabolicos (neurotransmisores, metabolismo energetico, factores de crecimiento y lipidos). A partir de esta combinacion de mecanismos biologicos se sugieren ejemplos de 'fenotipos sinapticos' en dos casos concretos de epilepsia genetica (SCN1A) y metabolica (epilepsia con respuesta a la piridoxina). Conclusiones. Una perspectiva holistica, entendiendo la diversidad de elementos relacionados y que suceden en determinados momentos del neurodesarrollo, puede ayudar a delinear fenotipos, vias de metabolismo sinaptico y conectividad cerebral, que faciliten no solo la comprension de la fisiopatologia, sino nuevas aproximaciones terapeuticas en epilepsia pediatrica.

  9. Charles Dickens (1812-1870) and epilepsy.

    2012-08-01

    To coincide with the bicentenary of the birth of Charles Dickens (1812-1870), accounts of epilepsy found in his novels and journalism have been collated and analyzed. From these, it may be inferred that Dickens was clearly aware of the difference between epilepsy and syncope and recognized different types of epilepsy and that seizures could be fatal. Speculations that Dickens himself suffered from epilepsy are not corroborated. Dickens's novelistic construction of epilepsy as a marker of criminality, as in the characters of Monks in Oliver Twist and Bradley Headstone in Our Mutual Friend, and perhaps of mental abnormality, was in keeping with conventional contemporary views of epilepsy, but his journalistic descriptions of individuals with epilepsy confined in the workhouse system indicate an awareness of the inadequacy of their care.

    2011-11-12

    Despite the introduction of many second-generation antiepileptic drugs (AEDs) in the last 2 decades, the proportion of individuals with pharmacoresistant epilepsy has not been reduced substantially compared with the late 1960s. All currently available AEDs also have limitations in terms of adverse effects and susceptibility to be involved in clinically important drug-drug interactions. Therefore, the search for potentially more effective and better tolerated agents is continuing. This article reviews the pharmacological and clinical profile of the latest compounds to receive marketing authorization. Since the beginning of 2008, three novel AEDs, lacosamide, eslicarbazepine acetate and retigabine (also known as ezogabine), have become commercially available in Europe, with lacosamide and retigabine also being licensed in the US. All three agents are indicated for the adjunctive treatment of focal seizures in adults. Eslicarbazepine acetate is a produg for eslicarbazepine, which acts by blocking voltage-dependent sodium channels. Lacosamide enhances the slow inactivation phase of voltage-dependent sodium channels, and retigabine potentiates neuronal M-currents by opening Kv 7.2-7.5 potassium channels. All three agents, which are well absorbed from the gastrointestinal tract, exhibit linear pharmacokinetics. Lacosamide is also available as an intravenous formulation intended as replacement therapy for patients temporarily unable to take oral medications. All three drugs are eliminated partly unchanged in urine and partly by biotransformation through glucuronide conjugation (eslicarbazepine, retigabine), N-acetylation (retigabine) and oxidative demethylation (lacosamide). The half-life is in the order of 8-20 hours for eslicarbazepine, 12-16 hours for lacosamide and 6-10 hours for retigabine. Based on the limited information available to date, the ability of these agents to cause pharmacokinetic drug interactions appears to be relatively modest, although

  11. Quantifying interictal metabolic activity in human temporal lobe epilepsy

    International Nuclear Information System (INIS)

    The majority of patients with complex partial seizures of unilateral temporal lobe origin have interictal temporal hypometabolism on [18F]fluorodeoxyglucose positron emission tomography (FDG PET) studies. Often, this hypometabolism extends to ipsilateral extratemporal sites. The use of accurately quantified metabolic data has been limited by the absence of an equally reliable method of anatomical analysis of PET images. We developed a standardized method for visual placement of anatomically configured regions of interest on FDG PET studies, which is particularly adapted to the widespread, asymmetric, and often severe interictal metabolic alterations of temporal lobe epilepsy. This method was applied by a single investigator, who was blind to the identity of subjects, to 10 normal control and 25 interictal temporal lobe epilepsy studies. All subjects had normal brain anatomical volumes on structural neuroimaging studies. The results demonstrate ipsilateral thalamic and temporal lobe involvement in the interictal hypometabolism of unilateral temporal lobe epilepsy. Ipsilateral frontal, parietal, and basal ganglial metabolism is also reduced, although not as markedly as is temporal and thalamic metabolism

    Approximately 10% of children are obese. Twin and adoption studies demonstrate a large genetic component to obesity, especially in adults. However, the increasing prevalence of obesity over the last 20 years can only be explained by environmental factors. In most obese individuals, no measurable differences in metabolism can be detected. Few children engage in regular physical activity. Obese children and adults uniformly underreport the amount of food they eat. Obesity is particularly related to increased consumption of high-fat foods. BMI is a quick and easy way to screen for childhood obesity. Treating childhood obesity relies on positive family support and lifestyle changes involving the whole family. Food preferences are influenced early by parental eating habits, and when developed in childhood, they tend to remain fairly constant into adulthood. Children learn to be active or inactive from their parents. In addition, physical activity (or more commonly, physical inactivity) habits that are established in childhood tend to persist into adulthood. Weight loss is usually followed by changes in appetite and metabolism, predisposing individuals to regain their weight. However, when the right family dynamics exist--a motivated child with supportive parents--long-term success is possible.
