    The seizures constitute one of the first causes of consultation in neurology and medical emergencies in all etary groups. The partial seizures are the most frequent form of clinical presentation specially those originated in the temporal lobes. In this revision article the author offers an update of the fisiopathogeny, the etiology and MRI findings in temporal epilepsy, and actualizes concepts derived from basic sciences. Selected cases of frequent pathologic causes contribute to illustrate this paper. In the physiopathology of the generalized seizures, alterations of the nets or thalamus cortical neuronal circuits and anomaly in the ionic canals functions have been demonstrated; in the partial seizures, particularly in the Mesial Temporal Sclerosis, alterations in the conformation of excitatory neo circuits have been verified. There are evidences of specific genetic seizures that express or appear sometime after birth, and others acquired, in which there is a variable time lapse between the action of a determined noxa and the installation of the clinical status, which suggest the existence of an epileptogenic mechanism as a gradual process in its development, and open a promissory field of investigation in search of preventive therapies. In many cases of acquired lesions seizures are related to the excitotoxicity mediated by glutamate as a possible trigger of the process. Besides, neuronal division has been demonstrated in the hippocampus, which could explain a neurogenic mechanism in the development of the seizures. The pathologic molecular findings in cortical malformations and the function of the glial cells in the neuronal homeostasis, contribute with data that sustain the neuro genesis of the seizures. The MRI provides a valuable information in Mesial Temporal Sclerosis, CNS tumoral lesions, neuronal migration disorders, vascular malformation, trauma and infections. Conclusion. The knowledge derived from areas as molecular biology, genetic and

    To compare the frequency of intrathecal immunoglobulin (Ig) synthesis in patients with symptomatic epilepsy and epilepsy of unknown etiology ('cryptogenic'). Patients with epileptic (n = 301) and non-epileptic (n = 10) seizures were retrospectively screened for autochthonous intrathecal Ig synthesis and oligoclonal bands (OCBs) in the cerebrospinal fluid. Intrathecal IgG/OCBs were detected in 8% of patients with epilepsies of unknown etiology, 5% of patients with first seizures of unknown cause and 0-4% of patients with epilepsy due to brain tumors, cerebrovascular disease or other etiologies. Intrathecal IgG/OCBs were not seen in patients with psychogenic seizures. Identical OCBs in serum and cerebrospinal fluid were more common in all patient groups (10-40% depending on underlying etiology). Intrathecal IgG synthesis/OCBs were observed slightly more frequently in patients with 'cryptogenic' epilepsy and with first seizures of unknown etiology than in other patient groups. However, this remained an infrequent finding and thus we could not confirm humoral immunity as a leading disease mechanism in patients with epilepsy in general or with unknown etiology in particular. © 2017 EAN.

  4. The causes of epilepsy: changing concepts of etiology of epilepsy over the past 150 years.

    This paper provides a survey of the changing concepts of the etiology of epilepsy from 1860 to 2010, focusing on the first two 50-year periods and outlining more briefly major developments in the past 50 years. Among the concepts reviewed in the first 100 years are: the division between predisposing and exciting causes, idiopathic and genuine epilepsy, organic epilepsy, the concept of "cause" being equivalent to "causal mechanism," Russell Reynolds etiological classification, the neurological taint and theories of degeneration, the self-perpetuating nature of seizures, reflex theories of etiology, autointoxication, heredity and eugenics, epilepsy due to brain disorders, the role of EEG and of hippocampal sclerosis, psychological theories of causation, and the multifactorial view of epilepsy etiology. In the past 50 years, the major advances in studying causation in epilepsy have been: clinical biochemistry, neuroimaging, molecular genetics, studies of mechanisms of epilepsy, better statistical methodologies and classification. A number of general observations can be made: the identification of "cause" is not as simple as it might at first appear; progress in the study of causation has been often erratic and travelled up many cul-de-sacs; theories of causation are heavily influenced by societal influences and fashion, and is also heavily dependent on applied methodologies; the recently explored possibility that the underlying inherited mechanisms of epilepsy are shared with other neuropsychiatric conditions is in effect a reinvention of the concept of the neurological trait, and this has ethical and social implications. Considering and classifying cause in terms of causal mechanism, as was suggested by Hughlings Jackson, is an ultimate goal. Wiley Periodicals, Inc. © 2011 International League Against Epilepsy.

    Autoimmune epilepsy is an underrecognized condition, and its true incidence is unknown. Identifying patients with an underlying autoimmune origin is critical because these patients' condition may remain refractory to conventional antiseizure medications but may respond to immunotherapy. To determine the prevalence of neurological autoantibodies (Abs) among adult patients with epilepsy of unknown etiology. Consecutive patients presenting to neurology services with new-onset epilepsy or established epilepsy of unknown etiology were identified. Serum samples were tested for autoimmune encephalitis Abs as well as thyroperoxidase (TPO) and glutamic acid decarboxylase 65 (GAD65) Abs. An antibody prevalence in epilepsy (APE) score based on clinical characteristics was assigned prospectively. Data were collected from June 1, 2015, to June 1, 2016. Presence of neurological Abs. A score based on clinical characteristics was assigned to estimate the probability of seropositivity prior to antibody test results. Good seizure outcome was estimated on the basis of significant reduction of seizure frequency at the first follow-up or seizure freedom. Of the 127 patients (68 males and 59 females) enrolled in the study, 15 were subsequently excluded after identification of an alternative diagnosis. Serum Abs suggesting a potential autoimmune etiology were detected in 39 (34.8%) cases. More than 1 Ab was detected in 7 patients (6.3%): 3 (2.7%) had TPO-Ab and voltage-gated potassium channel complex (VGKCc) Ab, 2 (1.8%) had GAD65-Ab and VGKCc-Ab, 1 had TPO-Ab and GAD65-Ab, and 1 had anti-Hu Ab and GAD65-Ab. Thirty-two patients (28.6%) had a single Ab marker. Among 112 patients included in the study, 15 (13.4%) had TPO-Ab, 14 (12.5%) had GAD65-Ab, 12 (10.7%) had VGKCc (4 of whom were positive for leucine-rich glioma-inactivated protein 1 [LGI1] Ab), and 4 (3.6%) had N-methyl-D-aspartate receptor (NMDAR) Ab. Even after excluding TPO-Ab and low-titer GAD65-Ab, Abs strongly suggesting an

    This study aimed to evaluate vestibular function in adults with chronic epilepsy of unknown etiology in the inter-ictal period. Epilepsy is a chronic medical disorder. Life-long therapy may be required in one-third of patients. Epilepsy is associated with comorbid somatic conditions which impairs patients' quality of life. This cross-sectional study included 28 with generalized tonic clonic (GTC) convulsions and 14 and 3 with temporal (TLE) and frontal lobe (FLE) epilepsies with secondary generalization (all were on regular carbamazepine therapy) and 40 healthy control subjects. The patients' mean age was 34.97 ± 7.35 years and the duration of illness was 18.75 ± 7.99 years. All underwent videonystagmography (VNG). Compared with controls, patients had frequent vestibular symptoms including dizziness (62.22%) (p = 0.0001) and sense of imbalance (44.44%) (p = 0.0001). Eleven patients (24.44%) had central vestibular dysfunction (p = 0.0001); 9 (20%) had mixed vestibular dysfunction and one (2.22%) had peripheral vestibular dysfunction (p = 0.0001). Abnormalities were observed in saccadic (44.4%) and pursuit (42.2%) eye movements, optokinetic nystagmus (42.2%) and positioning/positional (11.11%) and caloric (13.33%) testing. TLE and FLE were associated with more VNG abnormalities than GTC. No significant differences were observed in the demographic and clinical characteristics between patients with and without VNG abnormalities. Vestibular manifestations are frequent in patients with epilepsy. This may be a result of the permanent damaging effect of chronic epilepsy on the vestibular cortical areas and/or a toxic effect from prolonged carbamazepine therapy on the peripheral and central vestibular systems.

    Epilepsy represents a substantial personal and social burden worldwide. When addressing the multifaceted issues of epilepsy care, updated epidemiologic studies using recent guidelines are essential. The aim of this study was to find the prevalence and causes of epilepsy in a representative Norwegian county, implementing the new guidelines and terminology suggested by the International League Against Epilepsy (ILAE). Included in the study were all patients from Buskerud County in Norway with a diagnosis of epilepsy at Drammen Hospital and the National Center for Epilepsy at Oslo University Hospital. The study period was 1999-2014. Patients with active epilepsy were identified through a systematic review of medical records, containing information about case history, electroencephalography (EEG), cerebral magnetic resonance imaging (MRI), genetic tests, blood samples, treatment, and other investigations. Epilepsies were classified according to the revised terminology suggested by the ILAE in 2010. In a population of 272,228 inhabitants, 1,771 persons had active epilepsy. Point prevalence on January 1, 2014 was 0.65%. Of the subjects registered with a diagnostic code of epilepsy, 20% did not fulfill the ILAE criteria of the diagnosis. Epilepsy etiology was structural-metabolic in 43%, genetic/presumed genetic in 20%, and unknown in 32%. Due to lack of information, etiology could not be determined in 4%. Epilepsy is a common disorder, affecting 0.65% of the subjects in this cohort. Every fifth subject registered with a diagnosis of epilepsy was misdiagnosed. In those with a reliable epilepsy diagnosis, every third patient had an unknown etiology. Future advances in genetic research will probably lead to an increased identification of genetic and hopefully treatable causes of epilepsy.

    The incidences of seizures and epilepsy in the population show a peak after 60 years of age. Due to the lack of reported clinical aspects of seizure and epilepsy in the older patients in our region in Iran, this study was conducted to describe the clinical manifestation, etiology, differential diagnosis, and epilepsy subtypes of epilepsy and seizure. A cross-sectional retrospective study was performed on all consecutively elderly seizure and epilepsy patients, referred to the Epilepsy Association in the city of Qom, Iran over a 10-year period. A total of 466 patients aged >60 years were admitted. 31 % of the patients had epilepsy or seizure and 69 % of them had non-epileptic events. The most prevalent differential diagnoses in the beginning were syncope and cardiovascular disorders. The most frequent clinical symptom of epilepsy was generalized tonic-clonic seizures (75 %). The most common cause of seizure was systemic metabolic disorder (27 %). In epileptic elderly patients, no cause was ascertained for 38 % and the most frequently observed pathological factors were cerebrovascular diseases, which accounted for 24 %. The most common type of epileptic seizure was generalized epileptic seizures (75 %). 10 % of elderly epileptic patients suffered from status epilepticus, which was primarily caused by anoxia. Despite the rising rate and potentially profound physical and psychosocial effects of seizures and epilepsy, these disorders have received surprisingly little research focus and attention in Iran. Referring older patients to a specialist or a specialist epilepsy center allows speedy assessment, appropriate investigation and treatment, and less likely to miss the diagnosis.

    To report the increasing frequency with which temporal anteroinferior encephalocele is a cause of adult temporal lobe epilepsy, to illustrate the clinical and imaging characteristics of this condition, and to report its surgical treatment in a series of 23 adult patients. Epilepsy patients diagnosed with temporal anteroinferior encephalocele from January 2006 to December 2013 in a national epilepsy reference center were included in this noninterventional study. Twenty-three epilepsy patients (14 female, mean age 43.8 years) were diagnosed with temporal anteroinferior encephalocele in our institute. Thirteen patients had ≥2 encephaloceles; 7 cases presented bilaterally. The estimated frequency of this condition was 0.3% among MRI examinations performed due to newly diagnosed epilepsy (n = 6) and 1.9% among drug-resistant patients referred to our center (n = 17). Nine patients with local encephalocele disconnection (n = 4) or anterior temporal lobectomy and amygdalohippocampectomy (n = 5) have become seizure-free (Engel 1) for a mean 2.8 years (range 3 months-6.2 years) of follow-up. Three patients with local encephalocele disconnection were almost seizure-free or exhibited worthwhile improvement. Histologically, all 12 surgical patients had gliosis at the base of the encephalocele; some had cortical laminar disorganization (n = 5) or mild hippocampal degeneration (n = 1). The possibility of a temporal encephalocele should be considered when interpreting MRI examinations of patients with medically intractable focal epilepsy. These patients can significantly benefit from unitemporal epilepsy surgery, even in cases with bilateral encephaloceles. © 2015 American Academy of Neurology.

    This study aimed to identify long-term seizure outcome in pediatric nonsyndromic focal epilepsy after failure of serial antiepileptic drugs (AEDs) due to lack of efficacy. Children (1 month-17 years) with new-onset focal epilepsy not meeting the criteria for a defined electroclinical syndrome diagnosed between 1980 and 2009 while residing in Olmsted County, MN, were retrospectively identified. Medical records of those followed for ≥2 years were reviewed to assess etiology, the number of AEDs that failed due to lack of efficacy, and seizure outcome at final follow-up. Etiology was classified into structural/metabolic, genetic, or unknown. Favorable outcome was defined as seizure freedom ≥1 year, on or off AEDs, without prior epilepsy surgery. Poor outcome was defined as ongoing seizures in the preceding year or having undergone prior epilepsy surgery. Nonsyndromic focal epilepsy accounted for 275/468 (59%) of all patients with newly diagnosed epilepsy--of these, 256 (93%) were followed for a minimum of two years and were included in the study. Median duration of follow-up was 10.0 years. At least one AED had failed due to lack of efficacy in 100 (39.1%) children. Favorable outcomes occurred in 149/156 (95.5%) children with no AED failure, 16/30 (53.3%) with one AED failure, 8/25 (32%) with two AED failures, and only 2/45 (4.4%) with three AED failures. After two AED failures, the seizures of nearly one-quarter of children who had epilepsy with an unknown cause responded favorably to the third AED compared with only 7.8% of the cohort that had epilepsy with a structural/metabolic cause. Children with a remote brain insult had a significantly higher likelihood of favorable outcome with serial AEDs than those with other structural abnormalities. Etiology is an important determinant of pharmacoresistance in nonsyndromic focal epilepsy. Surgical evaluation should be considered after failure of 1-2 AEDs in those who have epilepsy with structural causes, excluding

    With improvement in magnetic resonance (MR) imaging techniques, the ability to identify lesions responsible for temporal lobe epilepsy has increased. MR imaging has also enabled the in vivo diagnosis of hippocampal sclerosis. Brain tumors are responsible for 2-4% of epilepsies in adult population and 10-20% of medically intractable epilepsy. The sensitivity of MR imaging in the diagnosis of tumors and other lesions of the temporal lobe (vascular malformations, etc.) is around 90%. Both hippocampal sclerosis and other temporal lobe lesions are amenable to surgical therapy with excellent postsurgical seizure outcome. In this article, we characterize and underline distinguishing features of the different pathological entities. We also suggest an approach to reviewing the MR images of an epileptic patient.

    Chronic epilepsy is estimated to affect more than 2 million people in China. However, data of its clinical characteristics was rarely reported in China. In the present study, we summarized the etiologic features and utilization patterns of antiepileptic drugs (AEDs) in people with chronic epilepsy in a tertiary medical center in China. We prospectively recruited people with chronic epilepsy treated at the Epilepsy Outpatient Clinic of Huashan Hospital during October 2009 to August 2013. Demographic data, clinical characteristics, AED treatment, epilepsy-associated risk factors and medical history, and results of supplementary examinations of each participant were collected retrospectively via an interviewer-administered questionnaire and confirmed by the medical records. Among 554 people with chronic epilepsy, 58.0% of them were male, 66.8% had focal seizure, and 29.2% had symptomatic cause. Developmental anomalies of cerebral structure (16.7%) and cerebral trauma (16.7%) shared the leading cause of symptomatic epilepsy among children with epilepsy. While cerebral trauma (29.1%) and cerebrovascular disorder (36.4%) were the most common causes in groups of adults and elderly. Fifty percent of participants were taking AED monotherapy. Proportions of people with idiopathic, cryptogenic and symptomatic epilepsy treated by multitherapy were 35%, 46% and 45.6%, respectively. Valproic acid (VPA) was the most frequently utilized AED as monotherapy (32.7%) and within multitherapy (62.5%). This hospital-based study reported that etiologic features were diverse in different age groups of people with chronic epilepsy. VPA was widely utilized to treat chronic epilepsy in mainland China.

    The understanding of causation of epilepsy, especially in resource poor African countries where prevalence rates are very high, would aid strategies for primary prevention. This study sought to determine the causes of epilepsy in Nigerian Africans and health-itinerary of patients with epilepsy. This was an observational, cross-sectional descriptive study of consecutive newly diagnosed adult patients with epilepsy using a mixed-methods approach of face-to-face in-depth interview of patients' parents and relations, health care personnel who had given medical attention at any time and telephone interview. A structured interview schedule was used to obtain demographic information, details of seizure variables, health seeking itinerary and history of previous hospitalizations. Data was analyzed descriptively with SPSS version 17. Three hundred and forty-two patients with epilepsy with a mean age of 31.4±11.98 years participated in the study. Most of the patients (68.1%; 233/342) were unemployed and students. There were 270 (78.9%) patients with generalized epilepsy. No identifiable etiology was found in 37.7%, but of the remaining 62.3%, the commonest causes included post traumatic (19.6%), recurrent childhood febrile convulsions (13.2%), post-stroke (6.7%), brain tumors (5.9%), neonatal jaundice (5.3%), birth-related asphyxia (5%) and history of previous CNS infections (4.7%). Family history of epilepsy was obtained in 9.9%, all of whom had primarily generalized seizures. 61.4% of them sought initial attention from the traditional healers or in prayer houses. This study showed the pattern of causes of epilepsy in Nigerian Africans. The health seeking behavior and itinerary of the PWE revealed a preference for traditional healers. There is need for health policies and epilepsy awareness campaigns to prevent causes of seizures and improve the knowledge of the public respectively. Copyright © 2013 British Epilepsy Association.

    Noninvasive brain stimulation, particularly transcranial magnetic stimulation (TMS) and transcranial direct current stimulation (tDCS), are emerging as realistic tools for seizure control. Numerous open-label trials and a few recent randomized controlled trials suggest the capacity of both techniques to suppress seizures. Additionally, specialized TMS protocols aimed to map cortical function and to measure cortical excitability may have realistic roles as diagnostic tools in epilepsy. As the prevalence of drug-resistant epilepsy has not changed in recent years, TMS and tDCS offer noninvasive and nonpharmacological options to improve control of intractable seizures. © 2013 Elsevier B.V.

    PET has added valuable information to our knowledge of the human epilepsies. The most important observations have been the identification of localized regions of interictal cerebral dysfunction in patients with partial epilepsy, revealed with PET as local hypometabolism, hypoperfusion, or (in one study) enhanced {mu}opiate receptor binding. The following general conclusions about the anatomy of epilepsy can be drawn from interictal PET studies: (1) interictal neuronal dysfunction is not limited to the site of ictal onset, nor to brain areas immediately adjacent to structural damage, (2) temporal lobe dysfunction is most commonly encountered, usually in association with primary epileptogenic lesions in mesial temporal structures, but also on occasion with lateral temporal or extratemporal epileptogenic lesions which preferentially propagate to mesial temporal structures to give rise to complex partial seizures. It is now accepted that interictal {sup 18}F-FDG PET correctly lateralises the primarily epileptic temporal lobe in approximately 70% of patients. As a consequence of inclusion of PET into the UCLA presurgical evaluation protocol, Engel et al. were able to operate on 28% of the patients without using invasive methods, (3) local isolated neocortical dysfunction associated with simple partial seizures is only rarely revealed by PET, (4) remote interictal cerebral dysfunction associated with complex partial seizures is not necessarily limited to the involved TL, since contralateral temporal, extemporal neocortical and cerebral dysfunction may also be seen, (5) a variety of anatomical patterns of interictal cerebral dysfunction occur in secondary generalized epilepsies, which may be related to symptoms and signs, (6) no diffuse or localized interictal cerebral dysfunction has been identified by PET in patients with primary generalized childhood absence seizures.

    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.

    It has been reported that epilepsy patients had higher risk of sudden death than that of the general population. However, in Japan, there is very little literature on the observational research conducted on sudden fatal events in epilepsy. We performed a single-center, retrospective study on all the out-of-hospital cardiac arrest (OHCA) patients treated in our emergency department between 2007 and 2013. Among the OHCA patients, we extracted those with a history of epilepsy and then analyzed the characteristics of the fatal events and the background of epilepsy. From 1,823 OHCA patients, a total of 10 cases were enrolled in our study. The median age was 34 years at the time of the incident [9-52 years; interquartile range (IQR), 24-45]. We determined that half of our cases resulted from external causes of death such as drowning and suffocation and the other half were classified as sudden unexpected death in epilepsy (SUDEP). In addition, asphyxia was implicated as the cause in eight cases. Only the two near-drowning patients were immediately resuscitated, but the remaining eight patients died. The median age of first onset of epilepsy was 12 years (0.5-30; IQR, 3-21), and the median disease duration was 25 years (4-38; IQR, 6-32). Patients with active epilepsy accounted for half of our series and they were undergoing poly anti-epileptic drug therapy. The fatal events related to epilepsy tended to occur in the younger adult by external causes. An appropriate therapeutic intervention and a thorough observation were needed for its prevention.

    Epilepsy affects people in all ages with the highest incidence in small children, particularly before age one year, and in elderly aged 65 years and older. In Sweden, between 4500-5000 persons develop epilepsy annually. Based on studies from North America and Europe, including the Nordic countries, the number of people with active epilepsy in Sweden is between 60000-70000. The lifetime risk for epilepsy up to age 85 years is 4-5 %, i.e. approximately every 25th person. The new epilepsy classification divides etiology into the following groups: structural, genetic, infectious, metabolic, immune and unknown. The majority (70%) of people with epilepsy eventually become seizure free. Epilepsy increases the risk of psychosocial problems and accidents. People with epilepsy have up to a 3-fold increase in mortality, mainly due to the underlying causes and epilepsy related deaths, e.g. status epilepticus, SUDEP and accidents. Somatic, psychiatric and neuropsychiatric comorbidities are common in epilepsy.

    Epilepsy is a common clinical entity in neurology clinics. The understanding of the genetics of epilepsy has undergone a sea change prompting re-classification by the International league against epilepsy recently. The prevalence rates of epilepsy in India are similar to those of developed nations. However, the large treatment gap is a major challenge to our public health system. Perinatal injuries are a major causative factor in pediatric group. We have discussed a few common etiologies such as neurocysticercosis and newer genetic epilepsy syndromes. We have also briefly touched upon the Indian experience in pediatric epilepsy surgery.

  12. Epilepsy and Mood Disorders

    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.

  13. Epilepsy and Mitochondrial Dysfunction

    Directory of Open Access Journals (Sweden)

    Russell P. Saneto DO, PhD

    2017-10-01

    Full Text Available Epilepsy is a common manifestation of mitochondrial disease. In a large cohort of children and adolescents with mitochondrial disease (n = 180, over 48% of patients developed seizures. The majority (68% of patients were younger than 3 years and medically intractable (90%. The electroencephalographic pattern of multiregional epileptiform discharges over the left and right hemisphere with background slowing occurred in 62%. The epilepsy syndrome, infantile spasms, was seen in 17%. Polymerase γ mutations were the most common genetic etiology of seizures, representing Alpers-Huttenlocher syndrome (14%. The severity of disease in those patients with epilepsy was significant, as 13% of patients experienced early death. Simply the loss of energy production cannot explain the development of seizures or all patients with mitochondrial dysfunction would have epilepsy. Until the various aspects of mitochondrial physiology that are involved in proper brain development are understood, epilepsy and its treatment will remain unsatisfactory.

  14. Comparisons of childhood trauma, alexithymia, and defensive styles in patients with psychogenic non-epileptic seizures vs. epilepsy: Implications for the etiology of conversion disorder.

    It has been theorized that conversion disorder is the result of emotion that cannot be experienced consciously as feeling states or put into words (i.e., alexithymia), but there is little confirming empirical evidence. We sought to characterize subjects with conversion disorder compared to subjects with a distinct medical illness, using the model of psychogenic non-epileptic seizures (PNES) vs. epilepsy (ES), on measures of childhood traumatic experience, alexithymia and maturity of psychological defensive strategies. All subjects admitted to the Epilepsy Monitoring Unit of the University of Cincinnati Medical Center were offered self-report questionnaires (Childhood Trauma Questionnaire, Toronto Alexithymia Scale-20 and Response Evaluation Measure-71) at the outset of evaluation. Diagnosis of each subject was confirmed by video-EEG and we compared subjects with PNES to those with ES on these measures. 82 subjects had ES AND 96 had PNES. Those with PNES were significantly more likely to have experienced childhood trauma in all domains (p=.005 to p=.05), and were significantly more likely to have alexithymia (p=.0267). There was a significant difference in the capacity to identify feelings, and a trend towards significance in capacity to describe feelings. There were no differences in defensive styles between the two groups. PNES diagnosis was associated with female sex, higher alexithymia scores and higher rates of childhood trauma, but not with differences in defensive styles compared to ES. These findings add empirical evidence for theories regarding the cause of conversion disorder and may aid in the design of prospective treatment trials in patients with conversion disorder.

    Hitiris, Nikolas; Mohanraj, Rajiv; Norrie, John; Brodie, Martin J

    2007-05-01

    All studies report an increased mortality risk for people with epilepsy compared with the general population. Population-based studies have demonstrated that the increased mortality is often related to the cause of the epilepsy. Common etiologies include neoplasia, cerebrovascular disease, and pneumonia. Deaths in selected cohorts, such as sudden unexpected death in epilepsy (SUDEP), status epilepticus (SE), suicides, and accidents are more frequently epilepsy-related. SUDEP is a particular cause for concern in younger people, and whether and when SUDEP should be discussed with patients with epilepsy remain problematic issues. Risk factors for SUDEP include generalized tonic-clonic seizures, increased seizure frequency, concomitant learning disability, and antiepileptic drug polypharmacy. The overall incidence of SE may be increasing, although case fatality rates remain constant. Mortality is frequently secondary to acute symptomatic disorders. Poor compliance with treatment in patients with epilepsy accounts for a small proportion of deaths from SE. The incidence of suicide is increased, particularly for individuals with epilepsy and comorbid psychiatric conditions. Late mortality figures in patients undergoing epilepsy surgery vary and are likely to reflect differences in case selection. Future studies of mortality should be prospective and follow agreed guidelines to better quantify risk and causation in individual populations.

    Full Text Available Management of epilepsy in elderly requires understanding the unique biochemical and pharmacological characteristics of these patients. Management decisions must be based on accurate classification of seizures or epilepsy syndromes, a thorough neurological assessment to define etiology, and a comprehensive assessment of the patient’s health and living situation. Concomitant illnesses such as neurological, psychiatric, metabolic, or cardiac disorders will require individualization of plans and instructions. Specific problems of treatment of epilepsy in the elderly compared to childhood patients are as follows: distinctive range of causes of epilepsy, distinctive differential diagnosis, concurrent pathologies unrelated to epilepsy, pharmacokinetic and pharmacodynamic differences, and distinctive psychosocial effects.

    Epilepsy, a disorder of unprovoked seizures is a multifaceted disease affecting individuals of all ages with a particular predilection for the very young and old. In addition to seizures, many patients often report cognitive and psychiatric problems associated with both the seizures themselves and its therapy. Epilepsy has numerous etiologies both idiopathic and acquired with a wide range of therapeutic responses. Despite numerous treatments available to control repetitive seizures including medications, diets, immunotherapy, surgery, and neuromodulatory devices, a large percentage of patients continue to suffer the consequences of uncontrolled seizures, which include psychosocial stigma and death.

    Status epilepticus is treated as a neurologic emergency and only later are the potential etiologies assessed. While sometimes the cause for status epilepticus is apparent (e.g., antiepileptic drug withdrawal), all too often it is not identified, even after extensive diagnostic testing has been performed. With emphasis on the less-common etiologies, this review will cover various probable and known causes of status epilepticus among adults, children, and those patients with refractory epilepsy.

    Human epilepsy is a common and heterogeneous condition in which genetics play an important etiological role. We begin by reviewing the past history of epilepsy genetics, a field that has traditionally included studies of pedigrees with epilepsy caused by defects in ion channels and neurotransmitters. We highlight important recent discoveries that have expanded the field beyond the realm of channels and neurotransmitters and that have challenged the notion that single genes produce single disorders. Finally, we project toward an exciting future for epilepsy genetics as large-scale collaborative phenotyping studies come face to face with new technologies in genomic medicine. PMID:21277190

A large treatment gap is still a public health problem. Benign epilepsies and West syndrome appear to be underrepresented in studies on classification of seizures/syndromes. Febrile seizures prevalence in India is similar to other countries and appear to be as benign. Risk factors of intractable epilepsy (IE) in Indian studies include early age of onset, neurodevelopmental abnormalities and certain seizure types. Perinatal injuries underlie many IE. Many IE are not truly intractable and respond to simple therapeutic measures. The ketogenic diet and surgery are other methods now being used in Indian centers. Neurocysticercosis and neonatal hypoglycemic brain injury, two widely prevalent etiologies are reviewed in detail.

    Objective: To define the clinical spectrum and etiology of progressive myoclonic epilepsies (PMEs) in Italy using a database developed by the Genetics Commission of the Italian League against Epilepsy. Methods: We collected clinical and laboratory data from patients referred to 25 Italian epilepsy centers regardless of whether a positive causative factor was identified. PMEs of undetermined origins were grouped using 2-step cluster analysis. Results: We collected clinical data from 204 patients, including 77 with a diagnosis of Unverricht-Lundborg disease and 37 with a diagnosis of Lafora body disease; 31 patients had PMEs due to rarer genetic causes, mainly neuronal ceroid lipofuscinoses. Two more patients had celiac disease. Despite extensive investigation, we found no definitive etiology for 57 patients. Cluster analysis indicated that these patients could be grouped into 2 clusters defined by age at disease onset, age at myoclonus onset, previous psychomotor delay, seizure characteristics, photosensitivity, associated signs other than those included in the cardinal definition of PME, and pathologic MRI findings. Conclusions: Information concerning the distribution of different genetic causes of PMEs may provide a framework for an updated diagnostic workup. Phenotypes of the patients with PME of undetermined cause varied widely. The presence of separate clusters suggests that novel forms of PME are yet to be clinically and genetically characterized.

    Epilepsy is the most prevalent chronic brain disease manifesting with epileptic seizures. Epilepsy itself is not one nosological entity, it rather includes several diseases with various etiology, clinics, course and therapy. Antiepileptic therapy aims seizure freedom without affecting psychical and physical functions. The therapy is in first line pharmacological. The choice of antiepileptic drug depends not only on the seizure phenomenology, but also on the respective type of epilepsy syndrome. Most patients achieve seizure freedom or at least significant seizure frequency reduction. In 20-30% of the patients is the pharmacotherapy ineffective. In these cases of refractory epilepsy therapeutical options include epilepsy surgery, vagal stimulation or ketogenic diet. Despite recent advances in the diagnostics and therapy, epilepsy remains a serious medical and social issue. (author)

  7. Epilepsy in the Elderly

    Directory of Open Access Journals (Sweden)

    2012-06-01

    Full Text Available Elderly people are the largest and continuously fastest growing population among patients with epilepsy. Elderly patients with epilepsy are very different from other age groups in many respects and clinicians shouldn’t treat them in the same way as younger adults. Accurate diagnosis of epilepsy in the elderly is much more difficult and atypical manifestations and misdiagnoses are certainly not the exception. Syncope is probably the most important differential diagnosis. High clinical suspicion and proper investigation are the best tools for prompt diagnosis. Etiologies of late-onset epilepsy are mainly symptomatic and cerebrovascular diseases are the most common causes in this age group, followed by degenerative diseases such as Alzheimer’s disease. It is appropriate to consider starting antiepileptic drug (AED treatment at the first-ever seizure in elderly patients who have remote symptomatic causes such as stroke and dementia. According to the high recurrence rate of seizure and the good response to AEDs in elderly patients, the proper choice from various AEDs for seizure control is very important. Decision-making for AED choice depends on many different factors, including pharmacological properties, efficacy, tolerability from side effects, drug interactions, and medical comorbidities. The newer AEDs with lesser adverse effects and fewer drug interactions appear to be reasonable treatment options for elderly patients. However, more evidence from clinical trials in this specific age group is warranted.

    Epilepsy represents a diverse group of disorders with primary and secondary genetic etiologies, as well as non-genetic causes. As more causative genes are identified, genetic testing is becoming increasingly important in the evaluation and management of epilepsy. This article outlines the clinical approach to epilepsy patients, with emphasis on genetic testing. Specific targeted tests are available for numerous individual genetic causes of epilepsy. Broader screening tests, such as chromosome microarray analysis and whole exome sequencing, have also been developed. As a standardized protocol for genetic testing has not been established, individualized diagnostic approaches to epilepsy patients should be used. Copyright © 2013 Elsevier Inc. All rights reserved.

    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.

    Epilepsy is a major public health problem worldwide. There are many misconceptions about people's knowledge and attitudes about epilepsy, which influence people's behavior towards patients with epilepsy. We conducted a cross-sectional study in Sohag University, a public Egyptian University, in Upper Egypt. We used an Arabic language designed questionnaire to assess people's knowledge about epilepsy and their attitudes towards patients with epilepsy. We included a total of 920 students in the study. 12.4% of study respondents had never heard of or read about epilepsy. Moreover, there was much misunderstanding about the etiology of epilepsy, as 68.2% of epileptic and 74.5% of nonepileptic respondents believe epilepsy is caused by evil spirits and evil eyes or due to psychiatric disorders. There were also many people who held negative attitudes towards patients with epilepsy in regards to major life milestones such as marriage and having children. Among nonepileptics, 54.5% believe epileptics should not marry and 49.9% believe they should not have children. Among patients with epilepsy, these percentages are 27.3% and 36.4% respectively. Knowledge about epilepsy is insufficient and should be increased. The attitudes towards patients with epilepsy are negative and should be changed in Upper Egypt. Copyright © 2018 Elsevier B.V.

    St Louis, Erik K; Cascino, Gregory D

    2016-02-01

    This review identifies the diverse and variable clinical presentations associated with epilepsy that may create challenges in diagnosis and treatment. Epilepsy has recently been redefined as a disease characterized by one or more seizures with a relatively high recurrence risk (ie, 60% or greater likelihood). The implication of this definition for therapy is that antiepileptic drug therapy may be initiated following a first seizure in certain situations.EEG remains the most commonly used study in the evaluation of people with epilepsy. Routine EEG may assist in diagnosis, classification of seizure type(s), identification of treatment, and monitoring the efficacy of therapy. Video-EEG monitoring permits seizure classification, assessment of psychogenic nonepileptic seizures, and evaluation of candidacy for epilepsy surgery. MRI is pivotal in elucidating the etiology of the seizure disorder and in suggesting the localization of seizure onset. This article reviews the new International League Against Epilepsy practical clinical definition for epilepsy and the differential diagnosis of other physiologic paroxysmal spells, including syncope, parasomnias, transient ischemic attacks, and migraine, as well as psychogenic nonepileptic seizures. The initial investigational approaches to new-onset epilepsy are considered, including neuroimaging and neurophysiologic investigations with interictal and ictal video-EEG. Neurologists should maintain a high index of suspicion for epilepsy when children or adults present with a single paroxysmal spell or recurrent episodic events.

    To obtain perspective on epilepsy in patients referred to tertiary centers in France, and describe etiology, epilepsy syndromes, and identify factors of drug resistance and comorbidities. We performed a cross-sectional analysis of the characteristics of 5,794 pediatric and adult patients with epilepsy included in a collaborative database in France between 2007 and 2013. Comparisons between groups used Student's t-test or Fisher's exact test for binary or categorical variables. Factors associated with drug resistance and intellectual disability were evaluated in multi-adjusted logistic regression models. Mean age at inclusion was 17.9 years; children accounted for 67%. Epilepsy was unclassified in 20% of patients, and etiology was unknown in 65%, including those with idiopathic epilepsies. Etiologies differed significantly in adult- when compared to pediatric-onset epilepsy; however, among focal structural epilepsies, mesial temporal lobe epilepsy with hippocampal sclerosis began as often in the pediatric as in adult age range. Drug resistance concerned 53% of 4,210 patients evaluable for seizure control and was highest in progressive myoclonic epilepsy (89%), metabolic diseases (84%), focal cortical dysplasia (70%), other cortical malformations (69%), and mesial temporal lobe epilepsy with hippocampal sclerosis (67%). Fifty-nine percent of patients with focal structural epilepsy and 69% with epileptic encephalopathies were drug resistant; however, 40-50% of patients with West syndrome and epileptic encephalopathy with continuous spike-and-waves during sleep were seizure-free. Ages at onset in infancy and in young adults shared the highest risk of drug resistance. Epilepsy onset in infancy comprised the highest risk of intellectual disability, whereas specific cognitive impairment affected 36% of children with idiopathic focal epilepsy. Our study provides a snapshot on epilepsy in patients referred to tertiary centers and discloses needs for diagnosis and treatment

    Abdominal epilepsy (AE) is a rather uncommon clinical entity in children that might create diagnostic confusion especially when it lacks the typical manifestations of an epileptic seizure. We report the case of a young boy having apparently unexplained episodes of paroxysmal abdominal symptoms with no other suggestion of an underlying epileptic disorder. The case also explains how the clinical presentation can be misleading unless a high index of suspicion is maintained to reach the ultimate diagnosis. (author)

    Learning Disorders (LD) are defined as disorders that interfere with academic performance or with daily activities that require reading, writing or mathematical skills in subjects with a normal intelligence quotient (IQ). The prevalence of LD in the general population has been found to be 2-10%, and reading disorders are the most frequent subtype. Epilepsy is one of the most common serious neurological disorders in childhood. LD are more common in children with epilepsy than in the general population. As a consequence, the risk of cognitive impairment in children with epilepsy is high, and a review of the literature needs to be fully presented. Narrative review including articles regarding LD in children with various epileptic syndromes published in the international medical literature. LD are more frequent among children with epilepsy. The etiology is multifactorial, being affected by the type of epileptic syndrome, the age of onset and the antiepileptic treatment being selected. LD can be either permanent or state-dependent. Each category has different treatment protocols and prognosis. Despite the fact that the findings of the studies discussed in our article support the evidence that epilepsy in childhood impairs the cognitive function, we should not underestimate the role of demographic and psychosocial factors on academic performance of children with epilepsy. Despite the high prevalence of LD, a healthy family and school environment can help reduce its impact on the patient's quality of life. © Springer-Verlag 2010

    Qatar is a small country on the Eastern coast of the Arabian Peninsula. Its population is a unique mixture of native citizens and immigrants. We aimed to describe the features of epilepsy in Qatar as such information is virtually lacking from the current literature. We summarized information retrospectively collected from 468 patients with epilepsy seen through the national health system adult neurology clinic. Epilepsy was classified as focal in 65.5% of the cases and generalized in 23%. Common causes of epilepsy were as follows: stroke (9%), hippocampal sclerosis (7%), infections (6%), and trauma (6%). Sixty-six percent of patients were receiving a single antiepileptic drug, with levetiracetam being the most frequently prescribed drug (41% of subjects). When the patients were divided by geographical background, remote infections caused the epilepsy in 15% of Asian patients (with neurocysticercosis accounting for 10%) but only in 1% of Qatari and 3% of Middle East/North African subjects (with no reported neurocysticercosis) (pepilepsy in Qatar. The geographical origin of patients adds to the heterogeneity of this disorder. Neurocysticercosis should be in the etiological differential diagnosis of epilepsy in patients coming from Southeast Asian countries, despite the fact that it is not endemic to Qatar. The choice of antiepileptic drugs is influenced by the availability of individual agents in the patients' native countries but had no bearing on the final seizure outcome.

    Full Text Available Autism and the other disorders in the autism spectrum are behaviorally defined syndromes that can be a prolonged disorder. The specific underlying neurophysiologic mechanisms simply not known, but probably several causes lead to disorders in the autism spectrum. This article is summary of recent research about etiology of autism but the search must continue. 1 Neurobiological origin, the neurobiological investigations show the role of dopamine and serotonin in pathogenesis of autism. 2 Genetic, studies in autism was established the hypothesis that genetic factors can be etiologically significant in subsets of patients. 3 With the Regional cerebral glucose metabolism measurement, autistic children had a left> right anterior rectal gyrus asymmetry as opposed to the normal right> left asymmetry in that region. 4 With the Regional cerebral blood flow measurement no cortical regional abnormalities were found. 5 Association of epilepsy and autism pediatric epilepsy lead to autistic regression. 6 Association of tuberous sclerosis and autism the number of tubers was significantly greater in individuals with a diagnosis of autism than in those without this diagnosis. 7 Embryological origin for autism, the results and two new lines of evidence that place the initiating injury for autism around the time of neural tube closure. 8 Obstetric complications and later autistic disorder, these data do not support the view that obstetric complications increase the risk for later autism. 9 Food allergy, recent findings show a relationship between food allergy and infantile autism. 10 Head circumferences measurement in children with autism show the large head circumference and increased growth.

    Purpose To determine the incidence and classification of new-onset epilepsy, as well as the distribution of epilepsy syndromes in a population-based group of children, using the newly proposed Report of the ILAE Commission on Classification and Terminology 2005–2009. Methods We identified all children residing in Olmsted County, MN, 1 month through 17 years with newly diagnosed epilepsy from 1980–2004. For each patient, epilepsy was classified into mode of onset, etiology, and syndrome or constellation (if present). Incidence rates were calculated overall and also separately for categories of mode of onset and etiology. Results The adjusted incidence rate of new-onset epilepsy in children was 44.5 cases per 100,000 persons per year. Incidence rates were highest in the first year of life and diminished with age. Mode of onset was focal in 68%, generalized/bilateral in 23%, spasms in 3% and unknown in 5%. Approximately half of children had an unknown etiology for their epilepsy, and of the remainder, 78 (22%) were genetic and 101 (28%) were structural/metabolic. A specific epilepsy syndrome could be defined at initial diagnosis in 99/359 (28%) children, but only 9/359 (3%) had a defined constellation. Conclusion Nearly half of childhood epilepsy is of “unknown” etiology. While a small proportion of this group met criteria for a known epilepsy syndrome, 41% of all childhood epilepsy is of “unknown” cause with no clear syndrome identified. Further work is needed to define more specific etiologies for this group. PMID:21482075

    At least one third of patients with active epilepsy suffer from significant impairment of their emotional well-being. A targeted examination for possible depression (irrespective of any social, financial or personal burdens) can identify patients who may benefit from medical attention and therapeutic support. Reliable screening instruments such as the Neurological Disorders Depression Inventory for Epilepsy (NDDI-E) are suitable for the timely identification of patients needing help. Neurologists should be capable of managing mild to moderate comorbid depression but referral to mental health specialists is mandatory in severe and difficult-to-treat depression, or if the patient is acutely suicidal. In terms of the therapeutic approach, it is essential first to optimize seizure control and minimize unwanted antiepileptic drug-related side effects. Psychotherapy for depression in epilepsy (including online self-treatment programs) is underutilized although it has proven effective in ten well-controlled trials. In contrast, the effectiveness of antidepressant drugs for depression in epilepsy is unknown. However, if modern antidepressants are used (e.g. SSRI, SNRI, NaSSA), concerns about an aggravation of seizures and or problematic interactions with antiepileptic drugs seem unwarranted. Epilepsy-related stress ("burden of epilepsy") explains depression in many patients but acute and temporary seizure-related states of depression or suicidality have also been reported. Limbic encephalitits may cause isolated mood alteration without any recognizable psychoetiological background indicating a possible role of neuroinflammation. This review will argue that, overall, a bio-psycho-social model best captures the currently available evidence relating to the etiology and treatment of depression as a comorbidity of epilepsy.

    Several chromosomal syndromes include brain dysfunction symptoms as mental retardation, developmental speech disorders and epilepsy. Authors present a case report of Angelman syndrome – neuro behavioral disorder associated with deletion in the maternal chromosome 15q 11-g13 causing mutation of the UBE3A gene. The main features consist of psychomotor retardation, developmental speech disorder, ataxia, tremor, hyperactivity, clapping hands, inadequate laughter and happiness, attention deficit and epilepsy. The later starts before the 3rd year of age in form of atypical absences, myoclonic and generalized tonic-clonic seizures. EEG typically shows episodes of slow activity with sharp waves occipitally. Prognosis is poor. Genetic syndromes importantly contribute to the etiology of epilepsy with early seizures. (author)

    To assess the yield of diagnostic exome sequencing (DES) and to characterize the molecular findings in characterized and novel disease genes in patients with epilepsy. In an unselected sample of 1,131 patients referred for DES, overall results were compared between patients with and without epilepsy. DES results were examined based on age of onset and epilepsy diagnosis. Positive/likely positive results were identified in 112/293 (38.2%) epilepsy patients compared with 210/732 (28.7%) patients without epilepsy (P = 0.004). The diagnostic yield in characterized disease genes among patients with epilepsy was 33.4% (105/314). KCNQ2, MECP2, FOXG1, IQSEC2, KMT2A, and STXBP1 were most commonly affected by de novo alterations. Patients with epileptic encephalopathies had the highest rate of positive findings (43.4%). A likely positive novel genetic etiology was proposed in 14/200 (7%) patients with epilepsy; this frequency was highest in patients with epileptic encephalopathies (17%). Three genes (COQ4, DNM1, and PURA) were initially reported as likely positive novel disease genes and were subsequently corroborated in independent peer-reviewed publications. DES with analysis and interpretation of both characterized and novel genetic etiologies is a useful diagnostic tool in epilepsy, particularly in severe early-onset epilepsy. The reporting on novel genetic etiologies may further increase the diagnostic yield.Genet Med 18 9, 898-905.

    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)

    2017-11-01

    Neurocysticercosis (NCC) is the most common parasitic infection of the central nervous system and a major risk factor for seizures and epilepsy. Seizure types in NCC vary largely across studies and seizure semiology is poorly understood. We discuss here the studies regarding seizure types and seizure semiology in NCC, and examine the clinical presentation in patients with NCC and drug-resistant epilepsy. We also provide evidence of the role of MRI and EEG in the diagnosis of NCC-related epilepsy. Focal seizures are reported in 60-90% of patients with NCC-related epilepsy, and around 90% of all seizures registered prospectively are focal not evolving to bilateral tonic-clonic seizures. A great number of cases suggest that seizure semiology is topographically related to NCC lesions. Patients with hippocampal sclerosis and NCC have different clinical and neurophysiological characteristics than those with hippocampal sclerosis alone. Different MRI protocols have allowed to better differentiate NCC from other etiologies. Lesions' stages might account on the chances of finding an interictal epileptiform discharge. Studies pursuing the seizure onset in patients with NCC are lacking and they are specially needed to determine both whether the reported events of individual cases are seizures, and whether they are related to the NCC lesion or lesions.

    Musicogenic reflex seizures (MRS) are a rare form of seizures described in patients with temporal lobe epilepsy (TLE), mainly of unknown etiology. Epilepsy with antibodies against glutamic acid decarboxylase (GAD-ab) is a form of autoimmune epilepsy for which no specific semiology has been described. To retrospectively review the incidence of MRS in the general epileptic population and in the series of patients with epilepsy and GAD-ab and to describe its clinical and paraclinical characteristics. Patients recorded between January 2010 and January 2016 in the Database of Bellvitge Hospital Epilepsy Unit were reviewed. From a group of 1510 epileptic patients, three reported MRS (0.0019%) (two patients with epilepsy and GAD-ab and one patient with cryptogenic TLE). The incidence of MRS in patients with epilepsy and GAD-ab was 2 of 22 (9%). Both patients had a normal magnetic resonance Imaging (MRI), but FDG-PET showed medial temporal lobe hypometabolism (unilateral or bilateral) in both and also in the insula in one of them. MRS (recorded via video-EEG[electroencephalography] in one patient) arose from the right temporal lobe. MRS may be a distinctive seizure type in patients with epilepsy and antiGADab. Determination of GAD-ab should be carried out in all cases of MRS, even those with normal structural MRI. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

  18. Next Generation Sequencing Methods for Diagnosis of Epilepsy Syndromes

    Directory of Open Access Journals (Sweden)

    2018-02-01

    Full Text Available Epilepsy is a neurological disorder characterized by an increased predisposition for seizures. Although this definition suggests that it is a single disorder, epilepsy encompasses a group of disorders with diverse aetiologies and outcomes. A genetic basis for epilepsy syndromes has been postulated for several decades, with several mutations in specific genes identified that have increased our understanding of the genetic influence on epilepsies. With 70-80% of epilepsy cases identified to have a genetic cause, there are now hundreds of genes identified to be associated with epilepsy syndromes which can be analyzed using next generation sequencing (NGS techniques such as targeted gene panels, whole exome sequencing (WES and whole genome sequencing (WGS. For effective use of these methodologies, diagnostic laboratories and clinicians require information on the relevant workflows including analysis and sequencing depth to understand the specific clinical application and diagnostic capabilities of these gene sequencing techniques. As epilepsy is a complex disorder, the differences associated with each technique influence the ability to form a diagnosis along with an accurate detection of the genetic etiology of the disorder. In addition, for diagnostic testing, an important parameter is the cost-effectiveness and the specific diagnostic outcome of each technique. Here, we review these commonly used NGS techniques to determine their suitability for application to epilepsy genetic diagnostic testing.

    2017-01-01

    Summary The ILAE Classification of the Epilepsies has been updated to reflect our gain in understanding of the epilepsies and their underlying mechanisms following the major scientific advances which have taken place since the last ratified classification in 1989. As a critical tool for the practising clinician, epilepsy classification must be relevant and dynamic to changes in thinking, yet robust and translatable to all areas of the globe. Its primary purpose is for diagnosis of patients, but it is also critical for epilepsy research, development of antiepileptic therapies and communication around the world. The new classification originates from a draft document submitted for public comments in 2013 which was revised to incorporate extensive feedback from the international epilepsy community over several rounds of consultation. It presents three levels, starting with seizure type where it assumes that the patient is having epileptic seizures as defined by the new 2017 ILAE Seizure Classification. After diagnosis of the seizure type, the next step is diagnosis of epilepsy type, including focal epilepsy, generalized epilepsy, combined generalized and focal epilepsy, and also an unknown epilepsy group. The third level is that of epilepsy syndrome where a specific syndromic diagnosis can be made. The new classification incorporates etiology along each stage, emphasizing the need to consider etiology at each step of diagnosis as it often carries significant treatment implications. Etiology is broken into six subgroups, selected because of their potential therapeutic consequences. New terminology is introduced such as developmental and epileptic encephalopathy. The term benign is replaced by the terms self-limited and pharmacoresponsive, to be used where appropriate. It is hoped that this new framework will assist in improving epilepsy care and research in the 21st century. PMID:28276062

    BACKGROUND: The etiology of inguinal hernias remains uncertain even though the lifetime risk of developing an inguinal hernia is 27% for men and 3% for women. The aim was to summarize the evidence on hernia etiology, with focus on differences between lateral and medial hernias. RESULTS: Lateral...... and medial hernias seem to have common as well as different etiologies. A patent processus vaginalis and increased cumulative mechanical exposure are risk factors for lateral hernias. Patients with medial hernias seem to have a more profoundly altered connective tissue architecture and homeostasis compared...... mechanisms why processus vaginalis fails to obliterate in certain patients should also be clarified. Not all patients with a patent processus vaginalis develop a lateral hernia, but increased intraabdominal pressure appears to be a contributing factor....

    Professor LAI Xinsheng 's experience of acupuncture combined with medication for epilepsy is summarized, which is explained from epilepsy's etiology and pathogenesis, diagnosis and treatment of acupuncture and medication, respectively. Besides, the theoretical foundation and use instruction of acupuncture technique " tong - yuan " for epilepsy are introduced. Professor LAI highly values the adherence to etiology and pathogenesis, pays attention to syndrome differentiation and searches for the primary disease cause. He proposes the wind, phlegm, stasis and deficiency are the pathogenesis of epilepsy, and points out acupuncture could be applied during attack stage and remittent stage, but electroacupuncture should be used with caution. Regulating spirit is the key for treating epilepsy. The combination of acupuncture and medication could regulate the governor vessel and guide qi to the origin, which have significant curative effect.

    The transition from a pediatric to adult health care system is challenging for many youths with epilepsy and their families. Recently, the Ministry of Health and Long-Term Care of the Province of Ontario, Canada, created a transition working group (TWG) to develop recommendations for the transition process for patients with epilepsy in the Province of Ontario. Herein we present an executive summary of this work. The TWG was composed of a multidisciplinary group of pediatric and adult epileptologists, psychiatrists, and family doctors from academia and from the community; neurologists from the community; nurses and social workers from pediatric and adult epilepsy programs; adolescent medicine physician specialists; a team of physicians, nurses, and social workers dedicated to patients with complex care needs; a lawyer; an occupational therapist; representatives from community epilepsy agencies; patients with epilepsy; parents of patients with epilepsy and severe intellectual disability; and project managers. Three main areas were addressed: (1) Diagnosis and Management of Seizures; 2) Mental Health and Psychosocial Needs; and 3) Financial, Community, and Legal Supports. Although there are no systematic studies on the outcomes of transition programs, the impressions of the TWG are as follows. Teenagers at risk of poor transition should be identified early. The care coordination between pediatric and adult neurologists and other specialists should begin before the actual transfer. The transition period is the ideal time to rethink the diagnosis and repeat diagnostic testing where indicated (particularly genetic testing, which now can uncover more etiologies than when patients were initially evaluated many years ago). Some screening tests should be repeated after the move to the adult system. The seven steps proposed herein may facilitate transition, thereby promoting uninterrupted and adequate care for youth with epilepsy leaving the pediatric system. Wiley

There is currently no cure or prevention for epilepsy, and 30% of affected persons are not controlled by current treatments, stressing the need for pursuing research efforts in the field within Horizon 2020. Priorities should include (1) development of innovative biomarkers and therapeutic targets and strategies, from gene and cell-based therapies to technologically advanced surgical treatment; (2) addressing issues raised by pediatric and aging populations, as well as by specific etiologies and comorbidities such as traumatic brain injury (TBI) and cognitive dysfunction, toward more personalized medicine and prevention; and (3) translational studies and clinical trials built upon well-established European consortia.

    Purpose To compare long-term outcome in a population-based group of children with cryptogenic vs symptomatic focal epilepsy diagnosed from 1980–2004 and to define the course of epilepsy in the cryptogenic group. Methods We identified all children residing in Olmsted County, MN, 1 month through 17 years with newly diagnosed, non-idiopathic focal epilepsy from 1980–2004. Children with idiopathic partial epilepsy syndromes were excluded. Medical records were reviewed to determine etiology, results of imaging and EEG studies, treatments used, and long-term outcome. Children were defined as having symptomatic epilepsy if they had a known genetic or structural/metabolic etiology, and as cryptogenic if they did not. Key Findings Of 359 children with newly-diagnosed epilepsy, 215 (60%) had non-idiopathic focal epilepsy. Of these, 206 (96%) were followed for more than 12 months. Ninety five children (46%) were classified as symptomatic. Median follow-up from diagnosis was similar in both groups, being 157 months (25%ile, 75%ile 89, 233) in the cryptogenic group vs 134 months (25%ile, 75%ile 78, 220) in the symptomatic group (p=0.26). Of 111 cryptogenic cases, 66% had normal cognition. Long-term outcome was significantly better in those with cryptogenic vs symptomatic etiology (intractable epilepsy at last follow-up, 7% vs 40%, p<0.001; seizure-freedom at last follow-up, 81% vs 55%, p<0.001). Of those who achieved seizure-freedom at final follow-up, 68% of the cryptogenic group versus only 46% of the symptomatic group were off antiepileptic medications (p=0.01). One third of the cryptogenic group had a remarkably benign disorder, with no seizures seen after initiation of medication, or in those who were untreated, after the second afebrile seizure. A further 5% had seizures within the first year but remained seizure-free thereafter. With the exception of perinatal complications, which predicted against seizure remission, no other factors were found to significantly

    Epidemiologic studies have shown that the incidence of epilepsy is the highest in the elderly population. Because the elderly constitutes the most rapidly growing population, epilepsy in this group is an important health issue worldwide. To identify the characteristics of epilepsy in the elderly, we reviewed our experience at a tertiary referral center in Japan. We searched all electronic medical records of the past 6 years at the epilepsy clinic of the hospital affiliated to our University-affiliated hospital. We defined an elderly person as an individual aged 65 years and above. All patients underwent history and physical examinations, 3T magnetic resonance imaging and/or computer tomography, and electroencephalogram (EEG). The diagnosis of epilepsy, age of onset, etiology, and antiepileptic medication were recorded. We identified 70 patients who developed epilepsy after the age of 65 years. The mean age of seizure onset was 73.1 years and 52.9% patients were males. Complex partial seizures (CPS) without secondarily generalization (n=33, 47.1%) were most frequent. The most frequent diagnosis was temporal lobe epilepsy (n=50, 71.4%). Etiological diagnosis was possible in nearly 50% patients, including those with cerebrovascular disease. A clear cause of epilepsy was not found (i.e., non-lesional epilepsy) in 52.8% patients. Interictal EEG revealed focal epileptiform discharges in 72.9% (n=51) patients. Of the 54 patients who were followed more than 1 year, 42 patients (77.8%) were on antiepileptic monotherapy and 52 patients (96.3%) had been seizure-free for more than 1 year. The most frequent diagnosis in our cohort of elderly persons with new-onset epilepsy was temporal lobe epilepsy. Non-lesional temporal lobe epilepsy was not uncommon. Epileptogenecity was relatively low in elderly patients and they responded well to antiepileptic medication. Copyright © 2013 British Epilepsy Association. Published by Elsevier Ltd.

  9. Clinical Application of Epilepsy Genetics in Africa: Is Now the Time?

    Directory of Open Access Journals (Sweden)

    Alina I. Esterhuizen

    2018-05-01

    Full Text Available Over 80% of people with epilepsy live in low- to middle-income countries where epilepsy is often undiagnosed and untreated due to limited resources and poor infrastructure. In Africa, the burden of epilepsy is exacerbated by increased risk factors such as central nervous system infections, perinatal insults, and traumatic brain injury. Despite the high incidence of these etiologies, the cause of epilepsy in over 60% of African children is unknown, suggesting a possible genetic origin. Large-scale genetic and genomic research in Europe and North America has revealed new genes and variants underlying disease in a range of epilepsy phenotypes. The relevance of this knowledge to patient care is especially evident among infants with early-onset epilepsies, where early genetic testing can confirm the diagnosis and direct treatment, potentially improving prognosis and quality of life. In Africa, however, genetic epilepsies are among the most under-investigated neurological disorders, and little knowledge currently exists on the genetics of epilepsy among African patients. The increased diversity on the continent may yield unique, important epilepsy-associated genotypes, currently absent from the North American or European diagnostic testing protocols. In this review, we propose that there is strong justification for developing the capacity to offer genetic testing for children with epilepsy in Africa, informed mostly by the existing counseling and interventional needs. Initial simple protocols involving well-recognized epilepsy genes will not only help patients but will give rise to further clinically relevant research, thus increasing knowledge and capacity.

  10. Effects of Epilepsy on Language Functions: Scoping Review and Data Mining Findings.

    2018-03-01

    This study involved a scoping review to identify possible gaps in the empirical description of language functioning in epilepsy in adults. With access to social network data, data mining was used to determine if individuals with epilepsy are expressing language-related concerns. For the scoping review, scientific databases were explored to identify pertinent articles. Findings regarding the nature of epilepsy etiologies, patient characteristics, tested language modalities, and language measures were compiled. Data mining focused on social network databases to obtain a set of relevant language-related posts. The search yielded 66 articles. Epilepsy etiologies except temporal lobe epilepsy and older adults were underrepresented. Most studies utilized aphasia tests and primarily assessed single-word productions; few studies included healthy control groups. Data mining revealed several posts regarding epilepsy-related language problems, including word retrieval, reading, writing, verbal memory difficulties, and negative effects of epilepsy treatment on language. Our findings underscore the need for future specification of the integrity of language in epilepsy, particularly with respect to discourse and high-level language abilities. Increased awareness of epilepsy-related language issues and understanding the patients' perspectives about their language concerns will allow researchers and speech-language pathologists to utilize appropriate assessments and improve quality of care.

    2017-12-01

    Recent advances in the field of epilepsy genetics have led to an increased fraction of patients with epilepsies where the etiology of the disease could be identified. Nevertheless, there is some criticism regarding the use of epilepsy genetics because in many cases the identification of a pathogenetic mutation does not lead to an adaptation of therapy or to an improved prognosis. In addition, the interpretation of genetic results might be complicated due to the considerable numbers of variants of unclear significance. This publication presents the arguments in favour of a broad use of genetic investigations for children with epilepsies. Several diseases where a genetic diagnosis does in fact have direct therapeutic consequences are mentioned. In addition, the indirect impact of an established etiology, encompassing the avoidance of unnecessary diagnostic measures, possibility of genetic counselling, and the easing of the psychologic burden for the caregivers, should not be underestimated. The arguments in favour of broad genetic diagnostics prevail notwithstanding the lack of relevant new developments regarding the therapy.

  13. New comments on the epilepsy of Fyodor Dostoevsky.

    Gastaut, H

    1984-08-01

    Based on recent data on the symptomatology of epileptic seizures and the interictal behavior shown by Dostoevsky, the author considers the debate open as to whether Dostoevsky presented primary generalized epilepsy or temporal lobe epilepsy. It is concluded that the most reasonable hypothesis on this subject is an eclectic one, wherein both etiologies of epilepsy would have been present with Dostoevsky displaying both of the following: a lesion of the temporal lobe of very discreet magnitude, thus lacking mental or somatic expression in the interictal period; and a constitutional predisposition to epilepsy of sufficient magnitude to render epileptogenic this otherwise silent temporal lesion, thus leading to a practically immediate secondary generalization of each seizure.

  14. Compression etiology in tendinopathy.

    2003-10-01

    Recent studies have emphasized that the etiology of tendinopathy is not as simple as was once thought. The etiology is likely to be multifactorial. Etiologic factors may include some of the traditional factors such as overuse, inflexibility, and equipment problems; however, other factors need to be considered as well, such as age-related tendon degeneration and biomechanical considerations as outlined in this article. More research is needed to determine the significance of stress-shielding and compression in tendinopathy. If they are confirmed to play a role, this finding may significantly alter our approach in both prevention and in treatment through exercise therapy. The current biomechanical studies indicate that certain joint positions are more likely to place tensile stress on the area of the tendon commonly affected by tendinopathy. These joint positions seem to be different than the traditional positions for stretching exercises used for prevention and rehabilitation of tendinopathic conditions. Incorporation of different joint positions during stretching exercises may exert more uniform, controlled tensile stress on these affected areas of the tendon and avoid stresshielding. These exercises may be able to better maintain the mechanical strength of that region of the tendon and thereby avoid injury. Alternatively, they could more uniformly stress a healing area of the tendon in a controlled manner, and thereby stimulate healing once an injury has occurred. Additional work will have to prove if a change in rehabilitation exercises is more efficacious that current techniques.

    Full Text Available Of the 70 million persons with epilepsy (PWE worldwide, nearly 12 million PWE are expected to reside in India; which contributes to nearly one-sixth of the global burden. This paper (first of the two part series provides an in-depth understanding of the epidemiological aspects of epilepsy in India for developing effective public health prevention and control programs. The overall prevalence (3.0-11.9 per 1,000 population and incidence (0.2-0.6 per 1,000 population per year data from recent studies in India on general population are comparable to the rates of high-income countries (HICs despite marked variations in population characteristics and study methodologies. There is a differential distribution of epilepsy among various sociodemographic and economic groups with higher rates reported for the male gender, rural population, and low socioeconomic status. A changing pattern in the age-specific occurrence of epilepsy with preponderance towards the older age group is noticed due to sociodemographic and epidemiological transition. Neuroinfections, neurocysticercosis (NCC, and neurotrauma along with birth injuries have emerged as major risk factors for secondary epilepsy. Despite its varied etiology (unknown and known, majority of the epilepsy are manageable in nature. This paper emphasizes the need for focused and targeted programs based on a life-course perspective and calls for a stronger public health approach based on equity for prevention, control, and management of epilepsy in India.

    It is seen at the results presented that in a high percentage of the patients suffering from posttraumatic epilepsia whom we examined pathological computertomographical and EEG-findings had to be compiled at the time of the examination. There was a discrepancy between this and the neurological findings, but in 80% of the cases, the pathological computer-tomographical and the EEG-findings were correspondent. These findings coincide with the results obtained by other examiners (Scollo-Lavizzari et al. 1976; Wessely et al. 1978). In our cases, the cause for the pathological findings consisted in covered craniocerebral traumata; in only 18% of the patients severe injuries such as durapenetrating traumata and sub- or epidural bleedings respectively were existent. In the case of computer-tomography, however, especially if the examination takes place only in the chronic stage, years after the trauma, problems occur in the causal classification of various lesion patterns. The typical focus of contusion - especially in connection with a one-sided ventricle extraction and expansion - can be easily classified ethiologically (Lanksch et al. 1978), as was the case in 38 of our patients. A hypodense region in the cerebral medulla or an atrophy afflicting the ventricle regularly cannot be placed in a traumatic etiology because of the individual computer-tomographical finding; under certain circumstances, however, an atrophy can be observed coming into existence on the development of an oedema to a defect in the substance by slow demacation can be seen.

    We assessed the outcome of patients with drug resistant epilepsy and neuronal antibodies who underwent epilepsy surgery. Retrospective study, information collected with a questionnaire sent to epilepsy surgery centers. Thirteen patients identified, with antibodies to GAD (8), Ma2 (2), Hu (1), LGI1 (1) or CASPR2 (1). Mean age at seizure onset: 23 years. Five patients had an encephalitic phase. Three had testicular tumors and five had autoimmune diseases. All had drug resistant temporal lobe epilepsy (median: 20 seizures/month). MRI showed unilateral temporal lobe abnormalities (mainly hippocampal sclerosis) in 9 patients, bilateral abnormalities in 3, and was normal in 1. Surgical procedures included anteromesial temporal lobectomy (10 patients), selective amygdalohippocampectomy (1), temporal pole resection (1) and radiofrequency ablation of mesial structures (1). Perivascular lymphocytic infiltrates were seen in 7/12 patients. One year outcome available in all patients, at 3 years in 9. At last visit 5/13 patients (38.5%) (with Ma2, Hu, LGI1, and 2 GAD antibodies) were in Engel's classes I or II. Epilepsy surgery may be an option for patients with drug resistant seizures associated with neuronal antibodies. Outcome seems to be worse than that expected in other etiologies, even in the presence of unilateral HS. Intracranial EEG may be required in some patients. Copyright © 2016 Elsevier B.V.

    Full Text Available Epilepsy is a highly prevalent chronic neurologic disorder and leads to social, behavioural, health and economic consequences. 'Treatment gap' varies from 10 per cent in developed countries to 75 per cent in low-income countries. Stigma and discrimination related to epilepsy are prevalent worldwide. Electroencephalography (EEG is considered the most important tool for evaluating the patient with epilepsy. Video-EEG monitoring is an important tool for confirming the seizure type and estimating the epileptogenic zone in the brain. Neuroimaging evaluation is important to determine the aetiology of the epilepsies. Genetic testing has increased the probability of identifying the causes of some types of epilepsies. Epilepsy can be treated in an affordable way with low-cost medications. Refractory epilepsies occur in approximately one-third of recently diagnosed patients with epilepsy. For this group of patients, there are options of surgical treatment, diets and neurostimulation to improve seizure control and quality of life. In poorly organized societies, there is a lack of prioritization of epilepsy in national health policies, limited resources for trained personnel and a shortage of basic antiepileptic medications. There is evidence of improvement in the understanding of epilepsy and a clear progress in the management of epileptic seizures in recent times.

    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.

RE may have different subtypes depending on the stimulus characteristic. There are significant clinical and electrophysiologic differences between different RE types. Visual stimuli-sensitive or photosensitive epilepsies constitute a large proportion of the RE and are mainly related to genetic causes. Reflex epilepsies may present with focal or generalized seizures due to specific triggers, and sometimes seizures may occur spontaneously. The stimuli can be external (light flashes, hot water, internal (emotion, thinking, or both and should be distinguished from triggering precipitants, which most epileptic patients could report such as emotional stress, sleep deprivation, alcohol, and menstrual cycle. Different genetic and acquired factors may play a role in etiology of RE. This review will provide a current overview of the triggering factors and management of reflex seizures.

    Full Text Available Juan José PozaDepartment of Neurology, Hospital Donostia, San Sebastián, SpainAbstract: Epilepsy among the elderly is a frequently occurring pathology, differing in etiology, clinical presentation and prognosis from those of young people. In addition, beyond a certain age, physiological modifications are produced in the metabolism which alter the pharmacokinetics of antiepileptic drugs (AEDs, increasing the risk of pharmacological interactions, already greater in these patients due to the frequency of poly-pharmacy. Furthermore, elderly patients are particularly sensitive to certain secondary effects of AEDs, as for example, cognitive disturbances, osteoporosis or weight increase. Given that the efficacy of the major AEDs is a priori quite similar, and that the epilepsies occurring in this age-group generally have a good prognosis, the selection of an AED will depend more upon its pharmacokinetics and ability to induce certain secondary effects than on its efficacy. In this respect, levetiracetam and pregabalin, followed by oxcarbazepine and lamotrigine have the most favorable pharmocokinetical profile. Moreover, on the whole these drugs have very few cognitive effects, do not induce osteoporosis and, with the exception of pregabalin, do not affect weight, making them the first selection for use in the treatment of epilepsy in the elderly.Keywords: epilepsy, the elderly, antiepileptic drugs

    Epileptic seizures have been known from time immemorial. Throughout the ages, however, ideas concerning the aetiology and treatment of epilepsy have changed considerably. Epilepsy is mentioned many times in the Pentateuch, where it is portrayed as a mysterious condition, whose symptoms, course and contingencies evade rational laws and explanations. In the Middle Ages, the accepted view which prevailed in social consciousness was that patients with epilepsy were possessed by Satan and other impure spirits. One common method of treatment of epileptic seizures was to submit the patient to cruel exorcisms. Patients were frequently injured in the process and some of them even died. Our understanding of epilepsy and its social consequences has improved considerably within the last century. The most significant progress as far as diagnosis and treatment of epilepsy is concerned took place in the last four decades of the twentieth century. Although we now know much more about epilepsy than we used to, this knowledge is still insufficiently popularized.

    Population-based studies on infantile epilepsy syndromes are scarce. Our aim was to provide syndrome-specific data on the incidence and outcome of epilepsy in a population-based cohort of infants with epilepsy onset in the first year. Included were all infants born in 1997 through 2006 whose epileptic seizures started before 12 months of age and who were residents of the Helsinki University Hospital district at the time of seizure onset. Patients were ascertained from hospital statistics, and all patient charts were reviewed. A reevaluation of the epilepsy syndromes, age at onset, etiology, and outcome at 24 months of age was based on data abstracted from the patient files. Inclusion criteria were fulfilled by 158 infants, of whom 92% were followed until age 24 months or death. The incidence of epilepsy in the first year was 124 of 100,000. An epilepsy syndrome recognized by the revised organization of epilepsies by ILAE was identified in 58% of the patients. The most common syndromes were West syndrome (41/100,000) and benign familial or nonfamilial infantile epilepsy (22/100,000). Etiology was structural-metabolic in 35%, genetic in 17%, and unknown in 48%. Early age at onset was associated with structural-metabolic etiology. Seven infants (4.4%) died before age 2 years. One infant with an SCN2A mutation died of sudden unexplained death in epilepsy (SUDEP). At 24 months, 58% of all children included in the cohort were seizure-free, and 46% had both seizure freedom and age-appropriate cognitive development. Age at onset was not associated with outcome when etiology was controlled for. Benign familial and nonfamilial infantile epilepsy appears to be more common than previously suggested, second only to West syndrome. Early age at onset is not an independent risk factor for poor outcome. Wiley Periodicals, Inc. © 2016 International League Against Epilepsy.

    The risk of premature mortality is increased in people with epilepsy. The reasons for this and how it may relate to epilepsy etiology remain unclear. The National General Practice Study of Epilepsy is a prospective, community-based cohort that includes 558 people with recurrent unprovoked seizures of whom 34% died during almost 25 years of follow-up. We assessed the underlying and immediate causes of death and their relationship to epilepsy etiology. Psychiatric and somatic comorbidities of epilepsy as predictors of mortality were scrutinized using adjusted Cox proportional hazards models. The 3 most common underlying causes of death were noncerebral neoplasm, cardiovascular, and cerebrovascular disease, accounting for 59% (111/189) of deaths, while epilepsy-related causes (e.g., sudden unexplained death in epilepsy) accounted for 3% (6/189) of deaths. In 23% (43/189) of individuals, the underlying cause of death was directly related to the epilepsy etiology; this was significantly more likely if death occurred within 2 years of the index seizure (percent ratio 4.28 [95% confidence interval 2.63-6.97]). Specific comorbidities independently associated with increased risk of mortality were neoplasms (primary cerebral and noncerebral neoplasm), certain neurologic diseases, and substance abuse. Comorbid diseases are important causes of death, as well as predictors of premature mortality in epilepsy. There is an especially strong relationship between cause of death and epilepsy etiology in the first 2 years after the index seizure. Addressing these issues may help stem the tide of premature mortality in epilepsy. © 2016 American Academy of Neurology.

    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.

  8. Pharmacogenomics in epilepsy.

    There is high variability in the response to antiepileptic treatment across people with epilepsy. Genetic factors significantly contribute to such variability. Recent advances in the genetics and neurobiology of the epilepsies are establishing the basis for a new era in the treatment of epilepsy, focused on each individual and their specific epilepsy. Variation in response to antiepileptic drug treatment may arise from genetic variation in a range of gene categories, including genes affecting drug pharmacokinetics, and drug pharmacodynamics, but also genes held to actually cause the epilepsy itself. From a purely pharmacogenetic perspective, there are few robust genetic findings with established evidence in epilepsy. Many findings are still controversial with anecdotal or less secure evidence and need further validation, e.g. variation in genes for transporter systems and antiepileptic drug targets. The increasing use of genetic sequencing and the results of large-scale collaborative projects may soon expand the established evidence. Precision medicine treatments represent a growing area of interest, focussing on reversing or circumventing the pathophysiological effects of specific gene mutations. This could lead to a dramatic improvement of the effectiveness and safety of epilepsy treatments, by targeting the biological mechanisms responsible for epilepsy in each specific individual. Whilst much has been written about epilepsy pharmacogenetics, there does now seem to be building momentum that promises to deliver results of use in clinic. Copyright © 2017 The Authors.

    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.

    2008-09-01

    Epilepsy directly affects 50 million people worldwide. Most can achieve excellent seizure control; however, people living with epilepsy continue to suffer from enacted or perceived stigma that is based on myths, misconceptions and misunderstandings that have persisted for thousands of years. This paper reviews the frequency and nature of stigma toward epilepsy. Significant negative attitudes prevail in the adolescent and adult public worldwide leading to loneliness and social avoidance both in school and in the workplace. People with epilepsy are often wrongly viewed as having mental health and antisocial issues and as being potentially violent toward others. Twenty-five percent of adults having epilepsy describe social stigma as a result of their epilepsy. They fear rejection and often feel shame or loneliness from this diagnosis. The psychosocial and social impact of epilepsy is significant. Yet few specific interventions have been demonstrated to alter this perception. The effect on public education is primarily short-term, while change over the long-term in attitudes and inaccurate beliefs have not presently been proven effective. School education programming demonstrates improved knowledge and attitude a month after a classroom intervention, but persisting change over a longer period of time has not been evaluated. In-depth adult psycho-educational programs for adults with epilepsy improves knowledge, coping skills and level of felt stigma. However these gains have not demonstrated persistence over time. Myths, misconceptions and misunderstandings about epilepsy continue and programs aimed at increasing knowledge and reducing negative public attitudes should be enhanced.

    The review of the literature on sleep disorders in epilepsy over the last two decades is presented. Paroxysmal phenomena of epileptic origin, nonepileptic paroxysms, antiepileptic drugs, polypragmasia and comorbid depression may affect sleep in epilepsy.Shortening of sleep time may cause seizures, hallucinations and depression because sleep plays an important role in the regulation of excitatory and inhibitory processes in the brain both in healthy people and in patients with epilepsy. According to the literature data, drugs (short treatment courses of hypnotics) or nonpharmacological methods should be used for treatment insomnia inpatients with epilepsy.

  14. Approaches to refractory epilepsy

    2014-01-01

    Full Text Available Epilepsy is one of the most common serious neurological conditions, and 30 to 40% of people with epilepsy have seizures that are not controlled by medication. Patients are considered to have refractory epilepsy if disabling seizures continue despite appropriate trials of two antiseizure drugs, either alone or in combination. At this point, patients should be referred to multidisciplinary epilepsy centers that perform specialized diagnostic testing to first determine whether they are, in fact, pharmacoresistant, and then, if so, offer alternative treatments. Apparent pharmacoresistance can result from a variety of situations, including noncompliance, seizures that are not epileptic, misdiagnosis of the seizure type or epilepsy syndrome, inappropriate use of medication, and lifestyle issues. For patients who are pharmacoresistant, surgical treatment offers the best opportunity for complete freedom from seizures. Surgically remediable epilepsy syndromes have been identified, but patients with more complicated epilepsy can also benefit from surgical treatment and require more specialized evaluation, including intracranial EEG monitoring. For patients who are not surgical candidates, or who are unwilling to consider surgery, a variety of other alternative treatments can be considered, including peripheral or central neurostimulation, ketogenic diet, and complementary and alternative approaches. When such alternative treatments are not appropriate or effective, quality of life can still be greatly improved by the psychological and social support services offered by multidisciplinary epilepsy centers. A major obstacle remains the fact that only a small proportion of patients with refractory epilepsy are referred for expert evaluation and treatment.

    This study assessed the prevalence rate of epilepsy and its causes in children and adolescents in one area of high deprivation in São Paulo, São Paulo, in Southeast Brazil. Between July 2005 and June 2006, 4947 families from a population of 22,013 inhabitants (including 10,405 children and adolescents between the ages of 0 and 16 years) living in the shantytown of Paraisópolis, were interviewed. In the first phase, a validated questionnaire was administered, to identify the occurrence of seizures. In the second phase, clinical history, neurologic examination, electroencephalography, and structural neuroimaging were performed. The diagnosis of epilepsy, including etiology, seizure types, and epileptic syndrome classification, was according to criteria of the International League Against Epilepsy. The screening phase identified 353 presumptive cases. In the second phase, 101 of these cases (33.8%) received the diagnosis of epilepsy. Crude prevalence of epilepsy was 9.7/1000 and prevalence of active epilepsy was 8.7/1000. Partial seizures were the most frequent seizure type (62/101). Symptomatic focal epilepsy was the most common form, and hypoxic-ischemic encephalopathy the most common etiology, reflecting the socioeconomic conditions of this specific population. Adequate public policies regarding perinatal assistance could help reduce the prevalence of epilepsy.

    The Burning Mouth Syndrome (BMS) is an oral mucosa pain--with or without inflammatory signs--without any specific lesion. It is mostly observed in women aged 40-60 years. This pain feels like a moderate/severe burning, and it occurs more frequently on the tongue, but it may also be felt at the gingiva, lips and jugal mucosa. It may worsen during the day, during stress and fatigue, when the patient speaks too much, or through eating of spicy/hot foods. The burning can be diminished with cold food, work and leisure. The goal of this review article is to consider possible BMS etiologies and join them in 4 groups to be better studied: local, systemic, emotional and idiopathic causes of pain. Knowing the different diagnoses of this syndrome, we can establish a protocol to manage these patients. Within the local pain group, we must investigate dental, allergic and infectious causes. Concerning systemic causes we need to look for connective tissue diseases, endocrine disorders, neurological diseases, nutritional deficits and salivary glands alterations that result in xerostomia. BMS etiology may be of difficult diagnosis, many times showing more than one cause for oral pain. A detailed interview, general physical examination, oral cavity and oropharynx inspection, and lab exams are essential to avoid a try and error treatment for these patients.

    Full Text Available Background Epilepsy affects 1% of children worldwide. The highest incidence is in the first year of life, and perinatal factors, such as hypoxic-ischemic injury, infection, and cortical malformation may play etiologic roles. Breast milk contains optimal nutrients for human brain in early life. Breastfeeding has been associated with lower risk of infections, better cognitive and psychomotor development. However, the role of breastfeeding in preventing childhood epilepsy remains unclear. Objective To evaluate an association between exclusive breastfeeding and childhood epilepsy. Methods A case-control study conducted from 1 May to 3 July 2013 involving children with epilepsy aged 6 months to 18 years who were attending pediatric outpatient clinic of Dr. Sardjito Hospital, Yogyakarta. Neurologically normal children, individually matched by age and sex, visiting the same clinic were considered as controls. Exclusion criteria were children with structural brain abnormality, history of epilepsy in family, and who had history of neonatal seizure, intracranial infection, febrile seizure, and head trauma before onset of epilepsy. History of breastfeeding was obtained by interviewing the parents. The difference of exclusively breastfeeding proportion between cases and controls was analyzed by McNemar test. Results The total number of participants was 68 cases and controls each. Subjects with epilepsy had lower proportion of exclusively breastfed (48.5% compared with controls (54.4%, but the difference was not statistically significant (P=0.541. Exclusively breastfeeding showed no statistical significance in decreasing risk of epilepsy (OR=0.71; 95%CI 0.32 to 1.61. Conclusions Exclusive breastfeeding for 4-6 months has no effect against childhood epilepsy.

    The mechanisms of the ketogenic diet remain unclear, but several predictors of response have been proposed. We aimed is to study the relationship between the etiology of epilepsy, cerebrospinal fluid neurotransmitters, pterins, and amino acids, and response to a ketogenic diet. We studied 60 patients who began classic ketogenic diet treatment for refractory epilepsy. In 24 of 60 individuals, we analyzed cerebrospinal fluid neurotransmitters, pterins, and amino acids in baseline conditions. Mean age at epilepsy onset was 24 months, 83.3% were focal epilepsies, and in 51.7% the etiology of the epilepsy was unknown. Six months after initiating the ketogenic diet, it was effective (greater than a 50% reduction in seizure frequency) in 31.6% of patients. We did not find a link between rate of efficacy for the ketogenic diet and etiologies of epilepsy, nor did we find a link between the rate of efficacy for the ketogenic diet and cerebrospinal fluid pterins and biogenic amines concentrations. However, we found statistically significant differences for lysine and arginine values in the cerebrospinal fluid between ketogenic diet responders and nonresponders, but not for the other amino acids analyzed. The values of some amino acids were significantly different in relationship with the ketogenic diet efficacy; however, the epilepsy etiology and the cerebrospinal fluid biogenic amine and pterin values were not.

    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.

    Is epilepsy truly an "African ailment"? We aimed to determine this, since international health agencies often refer to epilepsy as an African disease and the scientific literature has spoken the same tone. Various published materials, mainly reports, articles, were used to gather Asian and African evidence on various aspects of epilepsy and many of its risk and associated factors. Our results suggest that in no way can epilepsy be considered as an African ailment and such characterization is most likely based on popular beliefs rather than scientific evidence. In comparison to Africa, Asia has a 5.0% greater burden from all diseases, and is 17.0% more affected from neuropsychiatric disorders (that include epilepsy). Given that more countries in Asia are transitioning, there may be large demographic and lifestyle changes in the near future. However these changes are nowhere close to those expected in Africa. Moreover, 23 million Asians have epilepsy in comparison to 3.3 million Africans and 1.2 million sub-Saharan Africans. In comparison to Africa, Asia has more untreated patients, 55.0% more additional epilepsy cases every year, because of its larger population, with greater treatment cost and possibly higher premature mortality. Of several associated factors discussed herein, many have more importance for Asia than Africa. The current state of epilepsy in Asia is far less than ideal and there is an urgent need to recognize and accept the importance of epilepsy in Asia. In no way can epilepsy be considered as an African ailment. This is most likely based on popular beliefs rather than scientific evidence.

    Studies using relative measures, such as standardized mortality ratios, have shown that patients with epilepsy have an increased mortality. Reports on more direct and absolute measure such as life expectancy are sparse. We report potential years lost and how life expectancy has changed over 40 years in a cohort of patients with newly diagnosed epilepsy. We analyzed life expectancy in a cohort of adult patients diagnosed with definite epilepsy between 1970 and 2010. Those with brain tumor as cause of epilepsy were excluded. By retrospective probabilistic record linkage, living or death status was derived from the national death registry. We estimated life expectancy by a Weibull regression model using gender, age at diagnosis, epilepsy etiology, and year of diagnosis as covariates at time of epilepsy diagnosis, and 5, 10, 15, and 20 years after diagnosis. Results were compared to the general population, and 95% confidence intervals are given. There were 249 deaths (105 women, age at death 19.0-104.0 years) in 1,112 patients (11,978.4 person-years, 474 women, 638 men). A substantial decrease in life expectancy was observed for only a few subgroups, strongly depending on epilepsy etiology and time of diagnosis: time of life lost was highest in patients with symptomatic epilepsy diagnosed between 1970 and 1980; the impact declined with increasing time from diagnosis. Over half of the analyzed subgroups did not differ significantly from the general population. This effect was reversed in the later decades, and life expectancy was prolonged in some subgroups, reaching a maximum in those with newly diagnosed idiopathic and cryptogenic epilepsy between 2001 and 2010. Life expectancy is reduced in symptomatic epilepsies. However, in other subgroups, a prolonged life expectancy was found, which has not been reported previously. Reasons may be manifold and call for further study. © 2017 The Authors. Epilepsia published by Wiley Periodicals, Inc. on behalf of International

  2. Epilepsy and driving

    2015-05-01

    Full Text Available Epilepsy poses a risk for all participants in road traffic; therefore people with epilepsy do not meet the criteria for an unlimited driving license. Their driving is affected not only by epileptic seizures causing impaired consciousness and involuntary movements, but also by antiepileptic drugs with their many unwanted affects. The experts have not yet agreed on whether people with epilepsy have an increased risk of experiencing a road traffic accident. However, recent data suggests that the overall risk is lower compared to other medical conditions. Scientific evidence forms the basis of legislation, which by limiting people with epilepsy, enables all participants in road traffic to drive in the safest possible environment. The legislation that governs epilepsy and driving in Slovenia has been recently thoroughly reformed and thus allows a less discriminatory management of people with epilepsy. Although people with epilepsy experience many issues in their daily life, including their personal relationships and employment, they often list the need for driving as a top concern in surveys. General physicians play an important role in managing the issues of people with epilepsy.

    2018-01-01

    This article discusses etiology, pathogenesis, symptoms, and treatment of epilepsy, as described in Charaka Samhitā (translation: Charaka's Compendium) and Sushruta Samhitā, the two core texts of Ayurveda, an ancient system of medicine. Ayurveda emphasized amnesia and loss of consciousness as core features of epileptic seizures (Sanskrit: apasmar; translation: apa negation, smaran memory) and recognized that seizures occur due to a disturbance in brain function or flow of "humors" to the brain. Semiology of various seizure types was well described. Epilepsy was attributed to both internal and multiple exogenous factors. Treatment of epilepsy with formulations of naturally occurring substances, their compounding and use, is described in remarkable detail. Lifestyle modifications to protect people with epilepsy are also documented. Cognitive comorbidities of epilepsy were recognized. Although none of the Ayurveda formulations have any empirical evidence supporting their safety or efficacy in the treatment of epilepsy, studies are needed to generate relevant evidence, to recognize their hazards, and to integrate traditional and complementary systems of medicine with modern health care in an informed and safe manner.

    2015-08-01

    The aim of the study is to determine whether certain demographic, clinical, and psychosocial traits are associated with higher levels of felt stigma among persons with epilepsy (PWE) patients followed at a level 4 epilepsy center. We performed a direct survey of 182 consenting patients that included the Epilepsy Stigma Scale. On univariate analysis, higher levels of perceived stigma were associated with age, marital status, race, driving, work status, seizure etiology, Quality of Life in Epilepsy-10 (QOLIE-10) scores, and health literacy. Among coping reactions, the use of denial, behavioral disengagement and venting were also associated with higher degrees of felt stigma. Using multiple linear regression, being single, poorer QOLIE-10 scores, difficulties understanding written information, and the use of behavioral disengagement were independently associated with poorer scores on the Epilepsy Stigma Scale. Our study paints a compelling profile of a PWE who has greater perceived stigma. Programs that increase the level of social support, improve health literacy, and enhance quality of life may also help decrease the amount of felt stigma among PWE.

    Epilepsy is one of the commonest medical conditions affecting women of childbearing age1. In the most recent triennial report into maternal deaths in Ireland and the UK, two thirds of women who died had a medical condition. In this report, 14 maternal deaths during pregnancy and up to 42 days postpartum were attributable to epilepsy or seizures; a rate of 0.4 per 100,000 maternities. In 12 of these women’ the cause was sudden unexplained death in epilepsy. Thus, epilepsy remains a high-risk condition in pregnancy. The gold standard of care is a multidisciplinary approach involving obstetricians, a neurologist and an epilepsy nurse specialist2. Like other units in Ireland this multidisciplinary service is currently provided in the National Maternity Hospital’s maternal medicine clinic, in conjunction with neurology services in Beaumont Hospital.

    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

    Creativity can be defined as the ability to understand, develop, and express, in a systematic fashion, novel orderly relationships. It is sometimes difficult to separate cognitive skills requisite for the creative process from the drive that generates unique new ideas and associations. Epilepsy itself may affect the creative process. The treatment of epilepsy and its comorbidities, by altering or disrupting the same neural networks through antiseizure drugs (ASDs), treatment of epilepsy comorbidities, ablative surgery, or neurostimulation may also affect creativity. In this review, we discuss the potential mechanisms by which treatment can influence the creative process and review the literature on the consequences of therapy on different aspects of creativity in people with epilepsy.

    2014-09-01

    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.

  17. ADHD in idiopathic epilepsy

    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.

    Development of epilepsy was studied prospectively in a group of 77 consecutive stroke patients. Included were stroke patients less than 75 years old admitted within the first 3 days after the stroke. Excluded were patients with subarachnoid hemorrhage, vertebrobasilar stroke, and patients...... with other severe diseases. Cerebral angiography, CT, and EEG were performed in all patients. The patients were followed clinically for 2 to 4 years. Seven patients (9%) developed epilepsy. Of 23 patients with lesions involving the cortex, 6 (26%) developed epilepsy. Of 54 patients in whom the cortex...... was not involved, only 1 (2%) developed epilepsy. Patients with persisting paresis and cortical involvement seem to be at particularly high risk of developing epilepsy, as 50% of such patients (6 of 12) developed the disease....

    Epilepsy is the tendency to have unprovoked epileptic seizures. Anything causing structural or functional derangement of brain physiology may lead to seizures, and different conditions may express themselves solely by recurrent seizures and thus be labelled “epilepsy.” Worldwide, epilepsy is the most common serious neurological condition. The range of risk factors for the development of epilepsy varies with age and geographic location. Congenital, developmental and genetic conditions are mostly associated with the development of epilepsy in childhood, adolescence and early adulthood. Head trauma, infections of the central nervous system (CNS) and tumours may occur at any age and may lead to the development of epilepsy. Infections of the CNS are a major risk factor for epilepsy. The reported risk of unprovoked seizures in population-based cohorts of survivors of CNS infections from developed countries is between 6.8 and 8.3 %, and is much higher in resource-poor countries. In this review, the various viral, bacterial, fungal and parasitic infectious diseases of the CNS which result in seizures and epilepsy are discussed. The pathogenesis of epilepsy due to brain infections, as well as the role of experimental models to study mechanisms of epileptogenesis induced by infectious agents, is reviewed. The sterile (non-infectious) inflammatory response that occurs following brain insults is also discussed, as well as its overlap with inflammation due to infections, and the potential role in epileptogenesis. Furthermore, autoimmune encephalitis as a cause of seizures is reviewed. Potential strategies to prevent epilepsy resulting from brain infections and non-infectious inflammation are also considered.

    Knowledge about epilepsy and attitudes towards patients with epilepsy can affect measures taken to manage epilepsy and seizures. Support and understanding of mothers is invaluable in enabling children with epilepsy to develop normal life skills in living with epilepsy. In order to identify the educational needs of mothers of children with epilepsy, their knowledge, attitudes, and practices should be assessed. Therefore, we interviewed a group of mothers of children with epilepsy who were referred to a pediatric neurology clinic in a teaching hospital. The objective of this study was to assess knowledge, attitudes, and practices among mothers of children with epilepsy in order to identify their educational needs. In the period of August 2014 to January 2015, mothers whose children were diagnosed with epilepsy for at least six months participated in this cross sectional study, while returning to the neurology clinic of a pediatric hospital for usual follow-up. Data were collected through face-to-face interviews, held by trained female general practitioners. The interviewer used questions from a questionnaire. The knowledge section of the questionnaire included questions regarding prevalence and general knowledge about epilepsy, its etiology, symptoms, and seizure provoking factors. The attitudes section included statements regarding the mother's attitudes towards epilepsy and patients with the disease. The practice section included questions about first-aid measures taken by mothers who had witnessed generalized seizures by the time of interview. Responses of 206 participants were analyzed. At least 83% of mothers knew that epilepsy is a noncontagious neurological disorder which can be treated by regular drug therapy. In spite of demonstrating good knowledge scores, the majority of mothers felt the need for further training in epilepsy. More than 98% of mothers were against the idea that patients with epilepsy should hide their disease. Though having been referred to

  5. Professional liability. Etiology.

    Once again, I find Mr. Cooper quote-worthy for his statement, "It is incumbent upon the trial bar not to support the status quo merely because it is in our economic interest. Change is in the wind, and our tort system will be blown away on the winds of change for change's sake unless we participate in correcting deficiencies in the tort system and civil jury trial process." I suggest that we cannot ask for change for our own economic interest, nor can we lay blame exclusively to the other etiologic elements. We must improve those elements within our purview. The prayer of serenity may serve us well: God, grant me the serenity to accept the things I cannot change, the courage to change the things I can, and the wisdom to know the difference. In the game of professional liability litigation as played by the rules extant there are clearly winners and losers. The winners are the legal profession, both plaintiff and defense, and the insurers, who in the face of adversity simply increase premiums or withdraw from the market. The losers are the medical profession, the patients for whom they care and, in the broadest sense, our society as a whole. So as not to close on a note of gloom, one last quote. Lawrence H. Cooke, former Chief Judge of New York State, in remarks to the April 1986 National Symposium on Civil Justice Issues stated, "Our justice systems are beset with very real problems.(ABSTRACT TRUNCATED AT 250 WORDS)

    The impact of health and disease has led many artists to depict these themes for thousands of years. Specifically, epilepsy has been the subject of many famous works, likely because of the dramatic and misunderstood nature of the clinical presentation. It often evokes religious and even mythical processes. Epilepsy surgical treatment has revolutionized the care of selected patients and is a relatively recent advance. Epilepsy surgery has been depicted in very few artistic works. The first portrait showing a potential surgical treatment for patients with epilepsy was painted in the 12th century. During the Renaissance, Bosch famously provided artistic commentary on traditional beliefs in "The stone of madness". Several of these works demonstrate a surgeon extracting a stone from a patient's head, at one time believed to be the source of all "folly", including epileptic seizures, psychosis, intellectual disability, depression, and a variety of other illnesses. There are some contemporary art pieces including themes around epilepsy surgery, all of them depicting ancient Inca Empire procedures such as trepanning. This article reviews the most relevant artistic works related with epilepsy surgery and also its historical context at the time the work was produced. We also present a painting from the Mexican artist Eduardo Urbano Merino that represents the patient's journey through refractory epilepsy, investigations, and ultimately recovery. Through this work, the artist intends to communicate hope and reassurance to patients going through this difficult process. © 2013.

  7. Epilepsy is Dancing.

    2015-10-01

    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. Copyright © 2015 Elsevier Inc.

  8. [Tropical causes of epilepsy].

    Science.gov (United States)

    Carod-Artal, F J

    Eighty-five percent of all epileptics live in tropical regions. Prenatal risk factors, traumatic brain injuries and different parasitic infestations of the central nervous system (CNS) are the reasons behind the high prevalence of epilepsy. This work reviews the main parasitic infestations causing epilepsy in the tropics. Neurocysticercosis is the main cause of focal epilepsy in early adulthood in endemic areas (30-50%). All the phases of cysticerci (viable, transitional and calcified) are associated with epileptic seizures. Anti-cysticercus treatment helps get rid of cysticerci faster and reduces the risk of recurrence of seizures in patients with viable cysts. Symptomatic epilepsy can be the first manifestation of neuroschistosomiasis in patients without any systemic symptoms. The pseudotumoral form can trigger seizures secondary to the presence of granulomas and oedemas in the cerebral cortex. The eggs of Schistosoma japonicum are smaller, reach the CNS more easily and trigger epileptic seizures more frequently. Toxocariasis and sparganosis are other parasitic infestations that can give rise to symptomatic seizures. The risk factors for suffering chronic epilepsy after cerebral malaria are a positive familial history of epilepsy and a history of episodes of fever and cerebral malaria that began with coma or which progressed with multiple, prolonged epileptic seizures. About 20% of patients with cerebral infarction secondary to Chagas disease present late vascular epilepsy as a complication. Very few studies have been conducted to examine the prognosis, risk of recurrence and modification of the natural course of seizures associated with tropical parasitic infestations, except for the case of neurocysticercosis.

  11. The idiosyncratic aspects of the epilepsy of Fyodor Dostoevsky.

    Hughes, John R

    2005-11-01

    The goal of this article is to review the idiosyncratic aspects of the epilepsy of Fyodor Dostoevsky, one of the greatest writers of all time. The onset of his seizures is controversial, with some evidence pointing to his childhood and other reports that would place the onset in his teens or his twenties. His life in prison in Siberia and then in the Russian army is reviewed. His lifestyle included many factors that exacerbated his epilepsy, especially stress and sleep deprivation. His compulsion for gambling played an important role in producing great stress in his life, as he tried to reverse his poverty in the casinos. The most idiosyncratic aspect of his epilepsy was his so-called ecstatic aura. The etiology of his seizures was probably inherited as revealed by the seizures of his father and the status epilepticus and death of his young son. This great writer died from lung hemorrhages in 1891. Discussed in this review is that he did not likely have an aura of ecstasy; only a few such possible cases can be found in the world literature. For those few cases, evidence from electrical self-stimulation studies in animals and humans, investigating "pleasure centers," can be found to involve the limbic system, especially the septal nucleus. Data from the human amygdala provide evidence why almost all auras are, in fact, unpleasant and not pleasant. A review of recent data on the risks to offspring of epileptic fathers confirms that the etiology of Dostoevsky's epilepsy was probably inherited and that he probably had an idiopathic generalized epilepsy with minor involvement of the temporal lobe. A relationship is seen between his severe obsession with gambling and his epilepsy. Finally, Fyodor Dostoevsky is an excellent example of the "temporal lobe personality."

    Full Text Available Epilepsy and epileptic seizures are common brain disorders in the elderly and are associated with increased mortality that may be ascribed to the underlying disease or epilepsy-related causes.Objective To describe mortality predictors of epilepsy and epileptic seizures in elderly inpatients.Method Retrospective analysis was performed on hospitalized elderly who had epilepsy or epileptic seizures, from January 2009 to December 2010. One hundred and twenty patients were enrolled.Results The most common etiology was ischemic stroke (37%, followed by neoplasias (13%, hemorrhagic stroke (12%, dementias (11.4% and metabolic disturbances (5.5%. In a univariate analysis, disease duration (p = 0.04, status epilepticus (p < 0.001 and metabolic etiology (p = 0.005 were associated with mortality. However after adjustment by logistic regression, only status epilepticus remained an independent predictor of death (odds ratio = 13; 95%CI = 2.3 to 72; p = 0.004.Conclusion In this study status epilepticus was an independent risk factor for death during hospitalization.

  13. Memory Functioning in Children with Epilepsy: Frontal Lobe Epilepsy, Childhood Absence Epilepsy, and Benign Epilepsy with Centrotemporal Spikes

    Directory of Open Access Journals (Sweden)

    Ana Filipa Lopes

    2014-01-01

    Full Text Available Specific cognitive deficits have been identified in children with epilepsy irrespective of results on intelligence tests. Memory deficits are traditionally attributed to temporal lobe epilepsy, whereas the impact of frontal lobe epilepsy on memory functions has remained controversial. The aim of this study was the examination of memory abilities in other childhood common epilepsy syndromes (frontal lobe epilepsy (FLE, childhood absence epilepsy (CAE, and benign epilepsy with centrotemporal spikes (BECTS and the influence of epilepsy-related variables. Memory was examined in 90 children with epilepsy (each epilepsy group consisted of 30 children, aged 6–15, and compared with 30 control children. Children with FLE showed significant deficits in verbal and visual memory. In addition, type of epilepsy, earlier age at epilepsy onset, and longer active duration of epilepsy were associated with memory problems. 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.

    We investigated the voltage topography of interictal spikes in patients with temporal lobe epilepsy (TLE) to see whether topography was related to etiology for TLE. Adults with TLE, who had epilepsy surgery for drug-resistant seizures from 2011 until 2014 at Jefferson Comprehensive Epilepsy Center were selected. Two groups of patients were studied: patients with mesial temporal sclerosis (MTS) on MRI and those with other MRI findings. The voltage topography maps of the interictal spikes at the peak were created using BESA software. We classified the interictal spikes as polar, basal, lateral, or others. Thirty-four patients were studied, from which the characteristics of 340 spikes were investigated. The most common type of spike orientation was others (186 spikes; 54.7%), followed by lateral (146; 42.9%), polar (5; 1.5%), and basal (3; 0.9%). Characteristics of the voltage topography maps of the spikes between the two groups of patients were somewhat different. Five spikes in patients with MTS had polar orientation, but none of the spikes in patients with other MRI findings had polar orientation (odds ratio=6.98, 95% confidence interval=0.38 to 127.38; p=0.07). Scalp topographic mapping of interictal spikes has the potential to offer different information than visual inspection alone. The present results do not allow an immediate clinical application of our findings; however, detecting a polar spike in a patient with TLE may increase the possibility of mesial temporal sclerosis as the underlying etiology.

    Objective: To analyze the clinical syndromes and inheritance patterns of multiplex families with epilepsy toward the ultimate aim of uncovering the underlying molecular genetic basis. Methods: Following the referral of families with 2 or more relatives with epilepsy, individuals were classified into epilepsy syndromes. Families were classified into syndromes where at least 2 family members had a specific diagnosis. Pedigrees were analyzed and molecular genetic studies were performed as appropriate. Results: A total of 211 families were ascertained over an 11-year period in Israel. A total of 169 were classified into broad familial epilepsy syndrome groups: 61 generalized, 22 focal, 24 febrile seizure syndromes, 33 special syndromes, and 29 mixed. A total of 42 families remained unclassified. Pathogenic variants were identified in 49/211 families (23%). The majority were found in established epilepsy genes (e.g., SCN1A, KCNQ2, CSTB), but in 11 families, this cohort contributed to the initial discovery (e.g., KCNT1, PCDH19, TBC1D24). We expand the phenotypic spectrum of established epilepsy genes by reporting a familial LAMC3 homozygous variant, where the predominant phenotype was epilepsy with myoclonic-atonic seizures, and a pathogenic SCN1A variant in a family where in 5 siblings the phenotype was broadly consistent with Dravet syndrome, a disorder that usually occurs sporadically. Conclusion: A total of 80% of families were successfully classified, with pathogenic variants identified in 23%. The successful characterization of familial electroclinical and inheritance patterns has highlighted the value of studying multiplex families and their contribution towards uncovering the genetic basis of the epilepsies.

  18. [Economic aspects of epilepsy].

    Argumosa, A; Herranz, J L

    2000-06-01

    The economic magnitude of epilepsy is determined by its effect on the employment status of the patients, the cost of drug treatment for them and the healthcare system and the repercussion worldwide. Studies of the cost of the disease show that it has economic importance due to the sum of the direct and indirect costs caused by it. In the case of epilepsy, the results of studies in various countries led to the creation of a Commission on Economic Aspects of Epilepsy. The lack of epidemiological studies regarding epilepsy in Spain may explain the lack of publications on this subject in our country. The percentage of the total cost due to antiepileptic drugs is considerable and will probably increase in the future. The pharmaco-economic evaluation made by cost-benefit, cost-effectiveness, cost-usefulness analysis and studies to minimize costs should serve to use healthcare resources in the most effective manner and justify the rational use of the new antiepileptic drugs. The economic impact of epilepsy is added to the repercussion of the disease itself on the patient and his family. The different distribution of costs in children and adults with epilepsy suggest the need for intervention at an early age to try to reduce the long term economic and personal repercussions. The pharmaco-economic evaluation of the new antiepileptic drugs will make it clear whether their considerable cost is worth paying for their greater effectivity.

  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.

    2002-01-01

    In the article, the author develops an analysis of external and intrapsychic factors related to adults' insomnia. First she undertakes a literature review to describe semiological, evolutive and etiological levels of insomnia. From a semiological point of view, it is usual to differenciate initial insomnia (associated to the first phase of sleeping), intermittent insomnia (related to frequent awakenings) and final insomnia (related to early morning awakenings). From an evolutive point of view, we can identify transitory insomnia (characterized by frequent awakenings) and chronic insomnia. On the other hand, we are allowed to distinguish organic insomnia (disorder where an organic cerebral injury is demonstrated or suspected) from insomnias related to psychiatric or somatic disease or idiopathic one. Then, the author makes a literary review to identify various insomnia causes and points out. Social factors: insomnia rates are higher by divorced, separated or widowed people. Percentages are higher when scholastic level is weak, domestic income is less then 915 O a month, or by unemployed people. Besides, sleep quality is deteriorated by ageing. Sleeping and waking rhythm is able to loose its synchronization. Complaints about insomnia occur far frequently from women than men. Environmental factors: working constraints increase sleep disorders. It is possible to make the same conclusion when we have to face overcharge of external events, deep intrapsychic conflicts (related to grief, unemployment, damage or hospitalization) or interpersonal conflicts' situations where we are confronted to stress related to socio-affective environment, lack of social support or conjugal difficulties. Medical and physiologic causes: legs impatience syndrome, recurrent limbs shakings syndrome, breathe stop during sleep, narcolepsy, excessive medicine or hypnotic drugs use, some central nervous system injuries, every nocturnal awakening (related to aches.), surgical operation

We conducted a case-control study of 55 children with epilepsy (mean age 10y, range 4 to 16y; 27 males, 28 females) and their nearest-aged non-epileptic sibling (mean age 10y, range 4 to 18y; 26 males, 29 females). Epilepsy was idiopathic generalized in eight children (15%), symptomatic generalized in seven (13%), and focal in 40 (73%); the mean duration was 5 years 8 months. Parents or caregivers completed the Sleep Behavior Questionnaire (SBQ) and Child Behavior Checklist (CBCL) for patients and controls, and the Quality of Life in Childhood Epilepsy (QOLCE) for patients. Patients had a higher (more adverse) Total Sleep score (p<0.001) and scored worse than controls on nearly all subscales of the SBQ. In patients, higher Total Sleep scores were correlated with higher scores on the Withdrawn, Somatic complaints, Social problems, and Attention subscales of the CBCL, and significantly lower Total Quality of Life Scores. Refractory epilepsy, mental retardation, and remote symptomatic etiology predicted greater sleep problems in those with epilepsy. We conclude that children with epilepsy in this current study had significantly greater sleep problems than their non-epileptic siblings.

    The aim of this study was to explore information about epilepsy found on Arabic websites. The researchers collected information from the internet between November 2016 and January 2017. Information was obtained using Google and Yahoo search engines. Keywords used were the Arabic equivalent of the following two keywords: epilepsy (Al-saraa) and convulsion (Tashanoj). A total of 144 web pages addressing epilepsy in Arabic were reviewed. The majority of web pages were websites of medical institutions and general health websites, followed by informational and educational websites, others, blogs and websites of individuals, and news and media sites. Topics most commonly addressed were medical treatments for epilepsy (50% of all pages) followed by epilepsy definition (41%) and epilepsy etiology (34.7%). The results also revealed that the vast majority of web pages did not mention the source of information. Many web pages also did not provide author information. Only a small proportion of the web pages provided adequate information. Relatively few web pages provided inaccurate information or made sweeping generalizations. As a result, it is concluded that the findings of the present study suggest that development of more credible Arabic websites on epilepsy is needed. These websites need to go beyond basic information, offering more evidence-based and updated information about epilepsy. Copyright © 2017 Elsevier Inc. All rights reserved.

    Neurobehavioral comorbidities can be related to underlying etiology of epilepsy, epilepsy itself, and adverse effects of antiepileptic drugs. We examined the relationship between neurobehavioral comorbidities and putative risk factors for epilepsy in children with newly diagnosed epilepsy. We conducted a retrospective analysis of children aged ≤18years in 50 states and the District of Columbia, using the Truven Health MarketScan® commercial claims and encounters database from January 1, 2009 to December 31, 2013. The eligible study cohort was continuously enrolled throughout 2013 as well as enrolled for any days during a baseline period of at least the prior 2years. Newly diagnosed cases of epilepsy were defined by International Classification of Diseases, Ninth Revision, Clinical Modification-coded diagnoses of epilepsy or recurrent seizures and evidence of prescribed antiepileptic drugs during 2013, when neither seizure codes nor seizure medication claims were recorded during baseline periods. Twelve neurobehavioral comorbidities and eleven putative risk factors for epilepsy were measured. More than 6 million children were analyzed (male, 51%; mean age, 8.8years). A total of 7654 children were identified as having newly diagnosed epilepsy (125 per 100,000, 99% CI=122-129). Neurobehavioral comorbidities were more prevalent in children with epilepsy than children without epilepsy (60%, 99% CI=58.1-61.0 vs. 23%, CI=23.1-23.2). Children with epilepsy were far more likely to have multiple comorbidities (36%, 99% CI=34.3-37.1) than those without epilepsy (8%, 99% CI=7.45-7.51, Pepilepsy were detected in 28% (99% CI=26.9-29.6) of children with epilepsy. After controlling for demographics, neurobehavioral comorbidities, family history of epilepsy, and other risk factors than primary interest, neonatal seizures had the strongest independent association with the development of epilepsy (OR=29.8, 99% CI=23.7-37.3, Pepilepsy, those with both epilepsy and risk factors were

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

Early linkage studies have localized multiple loci that may harbor susceptibility genes to epilepsy, and mutational analyses have detected a number of mutations involved in both ion channel and nonion channel genes in patients with idiopathic epilepsy. Genome-wide studies of epilepsy have found copy number variants at 2q24.2-q24.3, 7q11.22, 15q11.2-q13.3, and 16p13.11-p13.2, some of which disrupt multiple genes, such as NRXN1, AUTS2, NLGN1, CNTNAP2, GRIN2A, PRRT2, NIPA2, and BMP5, implicated for neurodevelopmental disorders, including intellectual disability and autism. Unfortunately, only a few common genetic variants have been associated with epilepsy. Recent exome-sequencing studies have found some genetic mutations, most of which are located in nonion channel genes such as the LGI1, PRRT2, EFHC1, PRICKLE, RBFOX1, and DEPDC5 and in probands with rare forms of familial epilepsy, and some of these genes are involved with the neurodevelopment. Since epigenetics plays a role in neuronal function from embryogenesis and early brain development to tissue-specific gene expression, epigenetic regulation may contribute to the genetic mechanism of neurodevelopment through which a gene and the environment interacting with each other affect the development of epilepsy. This review focused on the analytic tools used to identify epilepsy and then provided a

    Fyodor M. Dostoevsky (Moscow, 1821-Saint Petersburg, 1881) suffered epilepsy throughout his whole literary career. The aim here is to understand his condition in light of his novels, correspondence, and his contemporaries' accounts as well as through the eyes of later generations of neurologists. From Murin (The landlady, 1847) to Smerdyakov (The brothers Karamazov, 1880), Dostoevsky portrayed up to six characters with epilepsy in his literature. The first symptoms of the disease presented in early adulthood, but he was only diagnosed with epilepsy a decade later. In 1863 he went abroad seeking expert advice from the famous neurologists Romberg and Trousseau. Dostoevsky made an intelligent use of epilepsy in his literature (of his experiential auras or dreamy states particularly) and through it found a way to freedom from perpetual military servitude. His case offers an insight into the natural history of epilepsy (a cryptogenic localization related one of either fronto-medial or temporal lobe origin using contemporary medical terms), thus inspiring later generations of writers and neurologists. Furthermore, it illustrates the good use of an ordinary neurological disorder by an extraordinary writer who transformed adversity into opportunity. © 2013 Elsevier B.V. All rights reserved.

    This study evaluated etiologic and risk factors affecting long-term prognoses of neurologic outcomes in newborns with neonatal seizures. We enrolled patients at chronologic ages of 23-44 months, referred to the Department of Pediatric Neurology, Istanbul Medical Faculty, from January 1, 2007-December 31, 2009, after manifesting seizures in their first postnatal 28 days. Of 112 newborns, 41 were female, 71 were male, 33 were preterm, and 79 were full-term. Perinatal asphyxia (28.6%) and intracranial hemorrhage (17%) were the most common causes of neonatal seizures. Cerebral palsy developed in 27.6% of patients during follow-up. The incidence of epilepsy was 35.7%. Almost 50% of patients manifested developmental delay in one or more areas. Global developmental delay was the most common (50.8%) neurologic disorder. The correlation between gestational age or birth weight and adverse outcomes was nonsignificant. Etiology, Apgar score, need for resuscitation at birth, background electroencephalogram, neonatal status epilepticus, cranial imaging findings, type/duration of antiepileptic treatment, and response to acute treatment were all strong prognostic factors in neurologic outcomes. Neonatal seizures pose a threat of neurologic sequelae for preterm and full-term infants. Although the number of recognized etiologic factors in neonatal seizures has increased because of improvements in neonatology and diagnostic methods, perinatal asphyxia remains the most common factor.

    It has been reported that patients with epilepsy often have insomnia and/or daytime sleepiness; the symptomatologic features differ in seizure types. Not only the administration of anti-epileptics, but also inappropriate sleep hygiene cause daytime sleepiness. In subjective assessment of sleepiness, we need to pay attention if it can correctly assess or not. The prevalence of obstructive sleep apnea in patients with epilepsy is approximately 10-30%. Sleep apnea deteriorates the seizure control because of worsen sleep condition by sleep apnea, especially in elderly patients. Some researchers report that continuous positive airway pressure was effective for seizure control. Patients with epilepsy occasionally have REM sleep behavior disorder as comorbidity. Examination using polysomnography is required for differential diagnosis.

    Full Text Available OBJECTIVE: Perfectionism has been recognized as a transdiagnostic factor that is relevant to anxiety disorders, eating disorders and depression. Despite the importance of perfectionism in psychopathology to date there has been no empirical test of an etiological model of perfectionism. METHOD: The present study aimed to address the paucity of research on the etiology of perfectionism by developing and testing an etiological model using a sample of 311 clients seeking treatment. RESULTS: Structural equation modeling showed a direct relationship between high Parental Expectations and Criticism, and Perfectionism. There was also an indirect relationship between Parental Bonding and Perfectionism that was mediated by core schemas of disconnection and rejection. Finally, it was found that Neuroticism had both an indirect relationship, which was mediated by core schemas, and a direct relationship with perfectionism. CONCLUSIONS: The study provided the first direct test of an etiological model of perfectionism to date. Clinical implications include investigating whether the inclusion of etiological factors in the understanding and treatment of perfectionism is effective.

    Full Text Available Cognitive impairments in epilepsy are a current problem in neurology. The basis of the idea on the pathogenesis of higher nervous system dysfunctions is the interaction of a few factors that include the form and duration of the disease, gender differences, and the impact of antiepileptic therapy. The role of interattack epileptiform changes in the development of cognitive deficit in adults and epileptic encephalopathies in children is discussed. Up-to-date neurophysiological and neuroimaging diagnostic methods allow the detection of new features in the course and progression of higher nervous system dysfunctions in epilepsy.

    Positron emission tomography (PET) was performed with the 18 F-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.

    In last few years there has been rapid increase in the knowledge of epilepsy genetics. Nowadays, it is estimated that genetic epilepsies include over than 30% of all epilepsy syndromes. Several genetic tests are now available for diagnostic purposes in clinical practice. In particular, next-generation sequencing has proven to be effective in revealing gene mutations causing epilepsies in up to a third of the patients. This has lead also to functional studies that have given insight into disease pathophysiology and consequently to the identification of potential therapeutic targets opening the way of precision medicine for epilepsy patients. This minireview is focused on the most recent advances in genetics of epilepsies. We will also overview the modern genomic technologies and illustrate the diagnostic pathways in patients with genetic epilepsies. Finally, the potential implications for a personalized treatment (precision medicine) are also discussed. Copyright © 2017 Elsevier B.V. All rights reserved.

    Educational outcomes for young people with epilepsy (YPE) in Hai District, Tanzania, are poor, as is commonly observed elsewhere in Sub-Saharan Africa. The reasons for this finding are not well understood, though stigma arising from supernatural concepts of epilepsy is frequently cited as a barrier to YPE accessing education. In this study, we aimed to explore the reasons why many YPE in Tanzania experience poor access to education, and elicit ways in which education could be improved for YPE according to teachers, parents and YPE. Ten focus group discussions with teachers were organized in Hai schools between March and May 2016. The themes arising from these discussions were identified, coded, analyzed and tested in semi-structured interviews with 19 YPE and 17 parents identified from a prevalent cohort of YPE identified in 2009. Behavioral problems and learning difficulties were cited as the main barriers to education for YPE. Other barriers included parental stigmatization, teachers' inadequate seizure management, and limited access to specialist schools. Teachers perceived that parents and YPE believe in spiritual etiology and traditional management for epilepsy. However, the majority of teachers, parents, and YPE cited biological etiology and management options, although understanding of epilepsy etiology and management could be improved amongst all groups. A multidimensional approach is needed to improve educational access, and hence outcomes, for YPE. Widespread community education is needed to improve knowledge of epilepsy etiology and management. Teachers require seizure management training, and parents need help to recognize YPE's right to education. Educational needs assessments would help to identify YPE requiring specialist schooling, and access to this could be improved. These interventions will likely reduce stigma, ensure appropriate academic and pastoral care at school, and thus enable YPE to attend, and succeed, in education. Copyright © 2017

    Previous studies examining seizures in patients with 22q11.2 deletion syndrome (22q11.2DS) have focused primarily on children and adolescents. In this study we investigated the prevalence and characteristics of seizures and epilepsy in an adult 22q11.2DS population. The medical records of 202 adult patients with 22q11.2DS were retrospectively reviewed for documentation of seizures, electroencephalography (EEG) reports, and magnetic resonance imaging (MRI) findings. Epilepsy status was assigned in accordance with 2010 International League Against Epilepsy Classification. Of 202 patients, 32 (15.8%) had a documented history of seizure. Of these 32, 23 (71.8%) had acute symptomatic seizures, usually associated with hypocalcemia and/or antipsychotic or antidepressant use. Nine patients (9/32, 28%; 9/202, 4%) met diagnostic criteria for epilepsy. Two patients had genetic generalized epilepsy; two patients had focal seizures of unknown etiology; two had epilepsy due to malformations of cortical development; in two the epilepsy was due to acquired structural changes; and in one patient the epilepsy could not be further classified. Similarly to children, the prevalence of epilepsy and acute symptomatic seizures in adults with 22q11.2DS is higher than in the general population. Hypocalcemia continues to be a risk factor for adults, but differently from kids, the main cause of seizures in adults with 22q11.2DS is exposure to antipsychotics and antidepressants. Further prospective studies are warranted to investigate how 22q11.2 microdeletion leads to an overall decreased seizure threshold.

    Full Text Available Mesial temporal sclerosis is the main pathological substrate present in refractory temporal lobe epilepsy and its presence is often related to the occurrence of febrile seizures in infancy. There is an on-going discussion on the nature of mesial temporal sclerosis as it related to epilepsy: cause or consequence. A previously normal child developed hyperosmolar coma after abdominal surgery at the age of 6. Three months afterwards he developed simple and complex partial seizures with an increasing frequency and refractory to multiple mono-and polytherapic drug regimens. He was evaluated for surgery at the age of 13. Ictal and interictal recordings showed left temporal lobe abnormalities. Early CT scaning suggested left temporal atrophy. MRI showed mesial temporal sclerosis. Neuropsichological testing showed verbal memory deficits and he passed a left carotid artery amytal injection. He was submitted to a cortico-amygdalo-hippocampectomy and has been seizure-free since then. The clinical data obtained from this patient suggest that at least in this case mesial temporal sclerosis would be related to the cause of epilepsy and not resultant from repeated seizure activity.A esclerose mesial temporal é o principal substrato anatomo-patológico envolvido na epilepsia refratária do lobo temporal e está frequentemente associada à ocorrência de convulsões febris na infância. Persiste até o momento intensa discussão se a esclerose mesial seria causa ou consequência da síndrome epiléptica. Uma criança previamente normal, desenvolveu coma hiperosmolar após intercorrência em cirurgia abdominal aos 6 anos de idade. Após 3 meses iniciaram-se crises parciais simples e complexas em frequência ascendente e refratárias a múltiplos esquemas terapêuticos em mono- e politerapia. Ele realizou investigação pré-operatória para epilepsia aos 13 anos de idade. Registros eletrencefalográficos de superfície ictais e interictais mostraram anormalidades

    To define the clinical spectrum and etiology of progressive myoclonic epilepsies (PMEs) in Italy using a database developed by the Genetics Commission of the Italian League against Epilepsy. We collected clinical and laboratory data from patients referred to 25 Italian epilepsy centers regardless of whether a positive causative factor was identified. PMEs of undetermined origins were grouped using 2-step cluster analysis. We collected clinical data from 204 patients, including 77 with a diagnosis of Unverricht-Lundborg disease and 37 with a diagnosis of Lafora body disease; 31 patients had PMEs due to rarer genetic causes, mainly neuronal ceroid lipofuscinoses. Two more patients had celiac disease. Despite extensive investigation, we found no definitive etiology for 57 patients. Cluster analysis indicated that these patients could be grouped into 2 clusters defined by age at disease onset, age at myoclonus onset, previous psychomotor delay, seizure characteristics, photosensitivity, associated signs other than those included in the cardinal definition of PME, and pathologic MRI findings. Information concerning the distribution of different genetic causes of PMEs may provide a framework for an updated diagnostic workup. Phenotypes of the patients with PME of undetermined cause varied widely. The presence of separate clusters suggests that novel forms of PME are yet to be clinically and genetically characterized.

    Epilepsy is a frequently misunderstood and highly stigmatized condition. Major treatment gaps exist across the world, most so in areas of financial constraint. Classification permits the best approaches to treatment and to ascertaining prognosis. The International League Against Epilepsy's new classification system emphasizes clinical aspects and utilizes all available resources to determine whether it is a focal or generalized epilepsy. The most important tools are a careful history, clinical examination, electroencephalography, and appropriate neuroimaging. Inadequate, delayed, and incomplete evaluation may lead to misdiagnosis and costly mismanagement. Treatment is generally pharmacological, with approximately 20 to 30% of patients eventually proving refractory to medications and thus becoming potential surgical candidates. The type of epilepsy, age, gender, comorbidities, drug interactions, and drug cost are important factors in choosing an antiepileptic drug (AED). The teratogenic potential of some AEDs, weight gain, and menstrual hormone-related issues are important considerations in women. The impact of AEDs on bone health is critical in all age groups, particularly in the elderly. Psychiatric problems, mostly depression and anxiety, can have a great impact on seizure control and overall quality of life. Finally, effective partnerships and collaborations can bring resources, both human and financial, to regions that would otherwise find it impossible to effect change on their own.

    Seizures are common in patients with brain tumors, and epilepsy can significantly impact patient quality of life. Therefore, a thorough understanding of rates and predictors of seizures, and the likelihood of seizure freedom after resection, is critical in the treatment of brain tumors. Among all tumor types, seizures are most common with glioneuronal tumors (70–80%), particularly in patients with frontotemporal or insular lesions. Seizures are also common in individuals with glioma, with the highest rates of epilepsy (60–75%) observed in patients with low-grade gliomas located in superficial cortical or insular regions. Approximately 20–50% of patients with meningioma and 20–35% of those with brain metastases also suffer from seizures. After tumor resection, approximately 60–90% are rendered seizure-free, with most favorable seizure outcomes seen in individuals with glioneuronal tumors. Gross total resection, earlier surgical therapy, and a lack of generalized seizures are common predictors of a favorable seizure outcome. With regard to anticonvulsant medication selection, evidence-based guidelines for the treatment of focal epilepsy should be followed, and individual patient factors should also be considered, including patient age, sex, organ dysfunction, comorbidity, or cotherapy. As concomitant chemotherapy commonly forms an essential part of glioma treatment, enzyme-inducing anticonvulsants should be avoided when possible. Seizure freedom is the ultimate goal in the treatment of brain tumor patients with epilepsy, given the adverse effects of seizures on quality of life. PMID:26948360

    The onset of epilepsy in brain systems involved in social communication and/or recognition of emotions can occasionally be the cause of autistic symptoms or may aggravate preexisting autistic symptoms. Knowing that cognitive and/or behavioral abnormalities can be the presenting and sometimes the only symptom of an epileptic disorder or can even be caused by paroxysmal EEG abnormalities without recognized seizures, the possibility that this may apply to autism has given rise to much debate. Epilepsy and/or epileptic EEG abnormalities are frequently associated with autistic disorders in children but this does not necessarily imply that they are the cause; great caution needs to be exercised before drawing any such conclusions. So far, there is no evidence that typical autism can be attributed to an epileptic disorder, even in those children with a history of regression after normal early development. Nevertheless, there are several early epilepsies (late infantile spasms, partial complex epilepsies, epilepsies with CSWS, early forms of Landau-Kleffner syndrome) and with different etiologies (tuberous sclerosis is an important model of these situations) in which a direct relationship between epilepsy and some features of autism may be suspected. In young children who primarily have language regression (and who may have autistic features) without evident cause, and in whom paroxysmal focal EEG abnormalities are also found, the possible direct role of epilepsy can only be evaluated in longitudinal studies.

    Cognitive impairment is frequently observed in patients with temporal lobe epilepsy. It is hypothesized that cumulative seizure exposure causes accelerated cognitive decline in patients with epilepsy. We investigated the influence of seizure frequency on cognitive decline in a rodent model for temporal lobe epilepsy. Neurobehavioral assessment was performed before and after surgery, after the induction of self-sustaining limbic status epilepticus (SSLSE), and in the chronic phase in which rats experienced recurrent seizures. Furthermore, we assessed potential confounders of memory performance. Rats showed a deficit in spatial working memory after the induction of the SSLSE, which endured in the chronic phase. A progressive decline in recognition memory developed in SSLSE rats. Confounding factors were absent. Seizure frequency and also the severity of the status epilepticus were not correlated with the severity of cognitive deficits. The effect of the seizure frequency on cognitive comorbidity in epilepsy has long been debated, possibly because of confounders such as antiepileptic medication and the heterogeneity of epileptic etiologies. In an animal model of temporal lobe epilepsy, we showed that a decrease in spatial working memory does not relate to the seizure frequency. This suggests for other mechanisms are responsible for memory decline and potentially a common pathophysiology of cognitive deterioration and the occurrence and development of epileptic seizures. Identifying this common denominator will allow development of more targeted interventions treating cognitive decline in patients with epilepsy. The treatment of interictal symptoms will increase the quality of life of many patients with epilepsy. Copyright © 2016 Elsevier Inc. All rights reserved.

    Four cases of double monsters are reported, including a rare case of craniofacial duplication (diprosopus). Based on the findings observed, etiological factors of these malformations are discussed. We suggest that exogenous (environmental) factors such as habits, way of life or religious practices of certain populations can influence the development of double monsters.

  11. The etiology of thyroid tumours

    1983-01-01

    The etiology of thyroid tumors is a complex subject, complicated by the fact that these tumors are not one entity, but separate neoplasms with different histology, evolution and prognosis. The recognized etiological factors of thyroid cancer include the iodine content of the diet, the inheritance, racial predispositions, the presence of an autoimmune thyroiditis and mostly, the exposure of the thyroid gland to external radiation following radiotherapy. The role played by these factors varies from one type of tumor to another. Thyroid radiation probably represents the most important factor in the development of a papillary carcinoma, with other factors (iodine-rich diet, inheritance, racial predispositions) having a minor role. The follicular carcinoma is more common in regions with low-iodine diet, therefore suggesting that TSH stimulation could be an etiological factor of these tumors. Thyroid radiation may also be carcinogenic for follicular carcinoma although less than for papillary carcinoma. Anaplastic carcinoma appears to originate from a papillary carcinoma already in the thyroid gland. In medullary carcinoma, inheritance plays a major role (autosomal dominant) and lymphomas occur in thyroids already affected by autoimmune thyroiditis. Recent experimental studies have suggested other possible cellular factors as responsible for the development of thyroid tumors. They include an alteration of the responsivity of TSH cellular receptors and the monoclonal mutation of C-cells. These new factors could provide a new insight on the etiology of thyroid tumors

    1992-01-01

    The present study investigated magnetic resonance imaging (MRI) features in temporal lobe epilepsy and correlated them with clinical variables, such as age, illness duration, past history, and the frequency of seizure. Cerebral MRI was performed in 45 patients with temporal lobe epilepsy of unknown etiology, using a 0.5 T and/or a 1.5 T MRI systems. The temporal lobe was seen as high signal intensity on T2-weighted images and/or proton density-weighted images in 6 patients, although it was missed on CT and T1-weighted images. The high intensity area seemed to reflect sclerosis of the temporal lobe. This finding was significantly associated with partial seizure. Of these patients, 3 had a history of febrile convulsions. Ten patients had slight dilatation of the inferior horn of the lateral ventricle. They were significantly old at the time of onset and examination, as compared with those without dilatation. Furthermore, 6 patients with unilateral dilatation were significantly younger than the other 4 with bilateral dilatation. Nine patients had small multiple high signal areas in white matter, mainly in the parietal lobe, which suggested vascular origin. These patients were significantly old at the time of onset and examination, as compared with those having no such findings. In depicting high signal intensity areas, a 1.5 T MRI system was not always superior to a 0.5 T MRI system. Proton density-weighted images were better than T2-weighted images in some patients.

    2015-06-01

    The association between autism spectrum disorder (ASD) and epilepsy has been described for decades, and yet we still lack the full understanding of this relationship both clinically and at the pathophysiologic level. This review evaluates the available data in the literature pertaining to the clinical characteristics of patients with autism spectrum disorder who develop epilepsy and, conversely, patients with epilepsy who develop autism spectrum disorder. Many studies demonstrate an increased risk of epilepsy in individuals with ASD, but rates vary widely. This variability is likely secondary to the different study methods employed, including the study population and definitions of the disorders. Established risk factors for an increased risk of epilepsy in patients with ASD include intellectual disability and female gender. There is some evidence of an increased risk of epilepsy associated with other factors such as ASD etiology (syndromic), severity of autistic features, developmental regression, and family history. No one epilepsy syndrome or seizure type has been associated, although focal or localization-related seizures are often reported. The age at seizure onset can vary from infancy to adulthood with some evidence of a bimodal age distribution. The severity and intractability of epilepsy in populations with ASD have not been well studied, and there is very little investigation of the role that epilepsy plays in the autism behavioral phenotype. There is evidence of abnormal EEGs (especially epileptiform abnormalities) in children with ASD even in the absence of clinical seizures, but very little is known about this phenomenon and what it means. The development of autism spectrum disorder in patients with epilepsy is less well studied, but there is evidence that the ASD risk is greater in those with epilepsy than in the general population. One of the risk factors is intellectual disability, and there is some evidence that the presence of a particular seizure

    Summary Preclinical research has facilitated the discovery of valuable drugs for the symptomatic treatment of epilepsy. Yet, despite these therapies, seizures are not adequately controlled in a third of all affected individuals, and comorbidities still impose a major burden on quality of life. The introduction of multiple new therapies into clinical use over the past two decades has done little to change this. There is an urgent demand to address the unmet clinical needs for: (a) new symptomatic anti-seizure treatments for drug-resistant seizures with improved efficacy/tolerability profiles, (b) disease modifying treatments that prevent or ameliorate the epileptogenic state, and (c) treatments for the common comorbidities that contribute to disability in people with epilepsy. New therapies also need to address the special needs of certain subpopulations, i.e. age- or gender-specific treatments. Preclinical development in these treatment areas is complex due to heterogeneity in presentation and etiology, and may need to be formulated with a specific seizure, epilepsy syndrome or comorbidity in mind. The aim of this report is to provide a framework that will help define future guidelines that improve and standardize the design, reporting, and validation of data across preclinical anti-epilepsy therapy development studies targeting drug-resistant seizures, epileptogenesis and comorbidities.

    Eleven epileptic men who complained of epilepsy and sexual dysfunction were submitted to a multidisciplinary evaluation. Mean age was 27 years (20-34), mean epilepsy duration was 19 years (0.5-32) and the mean seizure frequency was two by week (0-7). Ten patients had partial seizures and one other had myoclonic epilepsy. Ten patients were treated with antiepileptic drugs (phenytoin--1, carbamazepine--8, clonazepam--3, clobazam--2, valproic acid--3, vigabatrin--1). As defined in the DSM III-R, the complaints were: erectile disorder (9), hypoactive sexual desire disorder (4), frotteurism (4), inhibited orgasm (3), premature ejaculation (3), fetishism (2), voyeurism (2), exhibitionism (2), pedophilia (1) and sexual aversion disorder (1). Two patients showed hypogonadotropic hypogonadism on endocrinologic screening. Urological evaluation disclosed organic erectile dysfunction in other two. One patient had a diagnosis of psychogenic sexual disorder. In six patients a conclusive etiologic diagnosis was not reached. This report shows the multifactorial nature of sexual disorder in epilepsy and underlies the need of a multidisciplinar evaluation.

  20. Confronting the stigma of epilepsy

    2011-01-01

    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.

    2009-05-01

    Work on the classification of epileptic syndromes is ongoing, and many syndromes are still under discussion. In particular, special difficulty still persists in correctly classifying epilepsies with myoclonic seizures. The existence of special familial epileptic syndromes primarily showing myoclonic features has been recently suggested on the basis of a clear pattern of inheritance or on the identification of new chromosomal genetic loci linked to the disease. These forms in development include familial infantile myoclonic epilepsy (FIME), benign adult familial myoclonic epilepsy (BAFME), or autosomal dominant cortical myoclonus and epilepsy (ADCME), and, maybe, adult-onset myoclonic epilepsy (AME). In the future, the identification of responsible genes and the protein products will contribute to our understanding of the molecular pathways of epileptogenesis and provide neurobiologic criteria for the classification of epilepsies, beyond the different phenotypic expression.

    2013-01-01

    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)

    Ictal fear is a semiological feature which is commonly associated with mesial temporal lobe epilepsy. Here, we describe fear as a leading symptom in cryptogenic occipital lobe epilepsy. In a patient with negative MRI findings, intracranial EEG recordings documented a strict correlation between habitual ictal anxiety attacks and both spontaneous and stimulation-induced epileptic activity in a right occipital epileptogenic area with subsequent spreading to the symptomatogenic zone in the amygdala. Circumscribed occipital topectomy led to seizure freedom. Episodes of non-epileptic fear ceased shortly afterwards. This report provides insight into pathways of propagation of epileptic activity, illustrates different etiologies of pathologic fear and underlines the importance of ictal EEG recordings.

    2015-08-01

    In individuals with a comorbid autistic spectrum disorder and medically refractory epilepsy, vagus nerve stimulation may offer the potential of seizure control and a positive behavioral side effect profile. We aimed to examine the behavioral side effect profile using longitudinal and quantitative data and review the potential mechanisms behind behavioral changes. We present a case report of a 10-year-old boy with autistic spectrum disorder and epilepsy, who underwent vagus nerve stimulation subsequent to unsuccessful treatment with antiepileptic medication. Following vagus nerve stimulation implantation, initial, if temporary, improvement was observed in seizure control. Modest improvements were also observed in behavior and development, improvements which were observed independent of seizure control. Vagus nerve stimulation in autistic spectrum disorder is associated with modest behavioral improvement, with unidentified etiology, although several candidates for this improvement are evident.

    Reports of childhood epilepsies in temporal association with vaccination have had a great impact on the acceptance of vaccination programs by health care providers, but little is known about this possible temporal association and about the types of seizures following vaccinations. For these reasons the Italian League Against Epilepsy (LICE), in collaboration with other Italian scientific societies, has decided to generate Guidelines on Vaccinations and Epilepsy. The aim of Guidelines on Vaccinations and Epilepsy is to present recent unequivocal evidence from published reports on the possible relationship between vaccines and epilepsy in order to provide information about contraindications and risks of vaccinations in patients with epilepsy. The following main issues have been addressed: (1) whether contraindications to vaccinations exist in patients with febrile convulsions, epilepsy, and/or epileptic encephalopathies; and (2) whether any vaccinations can cause febrile seizures, epilepsy, and/or epileptic encephalopathies. Diphtheria-tetanus-pertussis (DTP) vaccination and measles, mumps, and rubella vaccination (MMR) increase significantly the risk of febrile seizures. Recent observations and data about the relationships between vaccination and epileptic encephalopathy show that some cases of apparent vaccine-induced encephalopathy could in fact be caused by an inherent genetic defect with no causal relationship with vaccination.

    Etiological diagnosis of leg ulcers must be the first step of treatment, even if we know that veinous disease is often present. We can build a clinical decisional diagram, which helps us to understand and not forget the other causes of chronic wounds and choose some basic examination, like ultrasound and histological findings. This diagnosis helps to choose the right treatment in order to cure even the oldest venous ulcers. Educational programs should be improved to prevent recurrence.

    2005-03-01

    Chronic diarrhea is a common syndrome. An etiological diagnosis is often reached through clinical history, physical examination and simple tests. In some cases, when the etiology is not found, the syndrome is called functional diarrhea, even though established criteria are often not fulfilled. We present the case of a patient with diarrhea for several months. The most common causes were ruled out through clinical history, physical examination, radiographic studies and laboratory tests, and the patient was diagnosed with functional diarrhea. Three months later, the patient presented a neck mass, and biopsy revealed medullary carcinoma of the thyroid. A review of recommendations for the systematic evaluation of chronic diarrhea is presented. A general approach should include careful history taking characteristics of diarrhea (onset, associated symptoms, epidemiological factors, iatrogenic causes such as laxative ingestion), a thorough physical examination with special attention to the anorectal region, and routine laboratory tests (complete blood count and serum chemistry). In addition, stool analysis including electrolytes (fecal osmotic gap), leukocytes, fecal occult blood, excess stool fat and laxative screening can yield important objective information to classify the diarrhea as: osmotic (osmotic gaps > 125 mOsm/Kg), secretory (osmotic gaps diarrhea described above. A systematic approach to the evaluation of chronic diarrhea is warranted. Medullary thyroid carcinoma and other endocrine syndromes causing chronic diarrhea are very rare. Measurement of serum peptide concentrations should only be performed when clinical presentation and findings in stool or radiographic studies suggest this etiology.

    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.

    Epilepsy is a common problem in the paediatric age group. Imaging plays a vital role in identifying the seizure focus. Cross-sectional imaging modalities like CT and MRI have had a major impact on the management of seizure disorders. MRI, because of its high contrast resolution and multiplanar capability is the ideal imaging modality but its use is restricted due to high cost. Computed tomography is cheaper and is the first, and often, the only modality used, especially in the under privileged areas of the world. In the tropical countries inflammatory granuloma are a common cause of epilepsy and CT is adequate to detect these lesions. Other causes include congenital abnormalities, neoplastic and vascular causes. (author)

    To review population-based studies of the prevalence and incidence of epilepsy worldwide and use meta-analytic techniques to explore factors that may explain heterogeneity between estimates. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses standards were followed. We searched MEDLINE and EMBASE for articles published on the prevalence or incidence of epilepsy since 1985. Abstract, full-text review, and data abstraction were conducted in duplicate. Meta-analyses and meta-regressions were used to explore the association between prevalence or incidence, age group, sex, country level income, and study quality. A total of 222 studies were included (197 on prevalence, 48 on incidence). The point prevalence of active epilepsy was 6.38 per 1,000 persons (95% confidence interval [95% CI] 5.57-7.30), while the lifetime prevalence was 7.60 per 1,000 persons (95% CI 6.17-9.38). The annual cumulative incidence of epilepsy was 67.77 per 100,000 persons (95% CI 56.69-81.03) while the incidence rate was 61.44 per 100,000 person-years (95% CI 50.75-74.38). The prevalence of epilepsy did not differ by age group, sex, or study quality. The active annual period prevalence, lifetime prevalence, and incidence rate of epilepsy were higher in low to middle income countries. Epilepsies of unknown etiology and those with generalized seizures had the highest prevalence. This study provides a comprehensive synthesis of the prevalence and incidence of epilepsy from published international studies and offers insight into factors that contribute to heterogeneity between estimates. Significant gaps (e.g., lack of incidence studies, stratification by age groups) were identified. Standardized reporting of future epidemiologic studies of epilepsy is needed. © 2016 American Academy of Neurology.

  14. Disruptions in cortico-subcortical covariance networks associated with anxiety in new-onset childhood epilepsy

    Camille Garcia-Ramos

    2016-01-01

    Full Text Available Anxiety disorders represent a prevalent psychiatric comorbidity in both adults and children with epilepsy for which the etiology remains controversial. Neurobiological contributions have been suggested, but only limited evidence suggests abnormal brain volumes particularly in children with epilepsy and anxiety. Since the brain develops in an organized fashion, covariance analyses between different brain regions can be investigated as a network and analyzed using graph theory methods. We examined 46 healthy children (HC and youth with recent onset idiopathic epilepsies with (n = 24 and without (n = 62 anxiety disorders. Graph theory (GT analyses based on the covariance between the volumes of 85 cortical/subcortical regions were investigated. Both groups with epilepsy demonstrated less inter-modular relationships in the synchronization of cortical/subcortical volumes compared to controls, with the epilepsy and anxiety group presenting the strongest modular organization. Frontal and occipital regions in non-anxious epilepsy, and areas throughout the brain in children with epilepsy and anxiety, showed the highest centrality compared to controls. Furthermore, most of the nodes correlating to amygdala volumes were subcortical structures, with the exception of the left insula and the right frontal pole, which presented high betweenness centrality (BC; therefore, their influence in the network is not necessarily local but potentially influencing other more distant regions. In conclusion, children with recent onset epilepsy and anxiety demonstrate large scale disruptions in cortical and subcortical brain regions. Network science may not only provide insight into the possible neurobiological correlates of important comorbidities of epilepsy, but also the ways that cortical and subcortical disruption occurs.

    This study was designed to assess knowledge and attitude with respect to epilepsy among secondary school students (epileptic and none) in Assiut city, Egypt. A cross sectional study was applied among secondary school students in Assiut city, Egypt. A 13-item questionnaire was self administered by 2226 students who selected randomly. All students either epileptic or non-epileptic had been heard about epilepsy. Only 7.1% of epileptic students and 8.5% of non-epileptic students thought that the epilepsy is a brain disease. Out of 2198 non-epileptic students, 28.4% thought that person with epilepsy (PWE) should not marry and 92% of them refused to marry from PWE. The correct knowledge of epilepsy was significantly positive correlated with positive attitude towards PWE. However, students still feel persons with epilepsy are stigmatized and are different from others. Secondary school students in Egypt have a vague knowledge about the etiology of epilepsy. Misconceptions about and negative attitudes towards epilepsy are unexpectedly high among those students. Copyright © 2011 Elsevier B.V. All rights reserved.

    A total of 132 women with epilepsy were confined in the period from 1978-1989. Their pregnancies and outcomes were analysed. The special aim was to find out if the anticonvulsive therapy has any correlation with the occurrence of fetal malformations in the studied group of women. In 43.9% of pregnant women with epilepsy, methyl-phenobarbitone as an anticonvulsive drug was administered, while carbamazepine was applied in 13.6% cases. A combination of phenytoin and phenobarbitone was prescribed in 18.9% of cases. Primidone was the drug of choice in 8% cases and 5.3% of patients were treated with various combinations of anticonvulsive drugs. Hyperemesis, threatened spontaneous abortion and premature labor complicated significantly more pregnancies in patients with epilepsy than on controls. Pregnancies from the studied group were terminated by the cesarean section in significantly more cases (11.2%) than in the control group (5.4%). Newborns from mothers with epilepsy had a statistically lower birthweight (3173 +/- 575 g) than those born from healthy mothers (3376 +/- 510g). Fifteen newborns or 11.2% were born with congenital malformations, while among the control group of newborns only two were malformed. It is noticed that the newborns from mothers treated with phenitoin and phenobarbitone had dysmorphic anomalies of the face more frequently. The drugs mentioned above interfere with the metabolism of K vitamin and as a result of this interreaction, mothers and newborns can suffer from coagulation disorders. In conclusion it is important to mention that no anticonvulsant drug seems to be absolutely safe when used during pregnancy since each of them has a teratogenic effect on the fetus.

    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.

  18. Neuroreceptor imaging in epilepsy

    1991-01-01

    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. [ 11 C]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 [ 11 C]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

    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.

  20. Dietary Therapies for Epilepsy

    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.

  1. Epilepsy and radiological investigations

    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 [et

    Extratemporal lobe epilepsies (ETLE) are characterized by the epileptogenic foci outside the temporal lobe. They have a wide spectrum of semiological presentation depending upon the site of origin. They can arise from frontal, parietal, occipital lobes and from hypothalamic hamartoma. We discuss in this review the semiology of different types of ETLE encountered in the epilepsy monitoring unit. PMID:24791090

    We assessed the relationship between adherence to epilepsy quality measures (EQM) and seizure control over 2-3 years in a retrospective cohort study. 6150 patients were identified at two large academic medical centers with a primary or secondary diagnosis of epilepsy, were 18-85 years old and seen in outpatient general neurology or epilepsy units between June 2011 and May 2014. Patients were included if: their initial visit was between June 2011 and June 2012, treatment was with ≥1 anti-seizure drug, there was ≥1 visit per year during the timeframe, and seizure frequency was documented at initial and final visits, yielding 162 patients/1055 visits from which socio-demographic, clinical and care quality data were abstracted. Quality care was assessed as (1) percent adherence to up to 8 eligible EQM, and (2) defect-free care (DFC: adherence to all eligible EQM). Seizure control (SC) was defined as ≥50% reduction in average seizures/month between initial and final visits. Chi-square and t-test compared care quality with seizure control. Logistic regression was used to assess the relationships between SC, quality of care and subspecialist involvement. Care quality, reflected by documentation of seizure frequency, addressing therapeutic interventions, and referral to a comprehensive epilepsy center, all exceeded 80% adherence. Care quality as reflected by documentation of seizure type, etiology or syndrome; assessment of side effects, counseling about epilepsy safety and women's issues, and screening for psychiatric disorders ranged from 40 to 57%. Mean EQM adherence across all applicable measures was associated with greater seizure control (p=0.0098). DFC was low (=8%) and did not covary with seizure control (p=0.55). The SC and non-SC groups only differed on epilepsy etiology (p=0.04). Exploratory analysis showed that mean quality scores are associated with seizure control (OR=4.9 [1.3-18.5], p=0.017) while controlling for the effect of subspecialty involvement

    Marijuana appears to have anti-epileptic effects in animals. It is not currently known if it is effective in patients with epilepsy. Some states in the United States of America have explicitly approved its use for epilepsy. To assess the efficacy and safety of cannabinoids when used as monotherapy or add-on treatment for people with epilepsy. We searched the Cochrane Epilepsy Group Specialized Register (9 September 2013), Cochrane Central Register of Controlled Trials (CENTRAL) in The Cochrane Library (2013, Issue 8), MEDLINE (Ovid) (9 September 2013), ISI Web of Knowledge (9 September 2013), CINAHL (EBSCOhost) (9 September 2013), and ClinicalTrials.gov (9 September 2013). In addition, we included studies we personally knew about that were not found by the searches, as well as searched the references in the identified studies. Randomized controlled trials (RCTs) whether blinded or not. Two authors independently selected trials for inclusion and extracted the data. The primary outcome investigated was seizure freedom at one year or more, or three times the longest interseizure interval. Secondary outcomes included responder rate at six months or more, objective quality of life data, and adverse events. We found four randomized trial reports that included a total of 48 patients, each of which used cannabidiol as the treatment agent. One report was an abstract and another was a letter to the editor. Anti-epileptic drugs were continued in all studies. Details of randomisation were not included in any study report. There was no investigation of whether the control and treatment participant groups were the same or different. All the reports were low quality.The four reports only answered the secondary outcome about adverse effects. None of the patients in the treatment groups suffered adverse effects. No reliable conclusions can be drawn at present regarding the efficacy of cannabinoids as a treatment for epilepsy. The dose of 200 to 300 mg daily of cannabidiol was

    To determine the prevalence and describe clinical characteristics of seizure disorders and epilepsy as causes of apparent life- threatening event (ALTE) in children admitted at the emergency and followed in a tertiary hospital. Cross-sectional study with prospective data collection using specific guidelines to determine the etiology of ALTE. During the study, 30 (4.2%) children admitted to the hospital had a diagnosis of ALTE. There was a predominance of males (73%) and term infants (70%). Neonatal neurological disorders and neuropsychomotor development delay were found respectively in 13.4% and 10% of the cases. Etiological investigation revealed that 50% of the cases were idiopathic, and 13.4% were caused by epilepsy or seizure disorders. Although all patients had recurrent ALTE events, epilepsy had not been previously suspected. Epilepsy should be included in the differential diagnosis of ALTE, particularly when events are recurrent.

    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. Forty four (61% children had hypocalcemia (less than 9 mg%, fifty seven (79% children had raised alkaline phosphatase levels (more than 270 IU.

The objective of the present work was to evaluate the clinical, EEG and brain imaging aspects in patients showing late-onset epilepsy. Fifty-five patients with late-onset epilepsy (older than 50 years were evaluated. They were composed of two groups according to the onset age of the epilepsy seizure (ES: 51-60 (G51-60 and over 60 (G60+ years. Focal ES predominated although they were less frequent in G60+. The occurrence of status epilepticus was high and more frequent in G60+ whereas seizures in series predominated in G51-60. Symptomatic epilepsy was more frequent and the vascular etiology predominated. Epileptiform activity was associated with a greater number of ES, and background activity abnormalities were more frequent in G60+. In conclusion, epilepsy with onset at over 50 was predominantly focal and symptomatic, with a high occurrence of status epilepticus and of seizures in series.

    Hypothyroidism is the result of inadequate production of thyroid hormone or inadequate action of thyroid hormone in target tissues. Primary hypothyroidism is the principal manifestation of hypothyroidism, but other causes include central deficiency of thyrotropin-releasing hormone or thyroid-stimulating hormone (TSH), or consumptive hypothyroidism from excessive inactivation of thyroid hormone. Subclinical hypothyroidism is present when there is elevated TSH but a normal free thyroxine level. Treatment involves oral administration of exogenous synthetic thyroid hormone. This review presents an update on the etiology and types of hypothyroidism, including subclinical disease; drugs and thyroid function; and diagnosis and treatment of hypothyroidism.

    Language and social skills are essential for intrapersonal and interpersonal functioning and quality of life. Since epilepsy impacts these important domains of individuals' functioning, understanding the psychosocial and biological factors involved in the relationship among epilepsy, language, and social skills has important theoretical and clinical implications. This review first describes the psychosocial and biological factors involved in the association between language and social behavior in children and in adults and their relevance for epilepsy. It reviews the findings of studies of social skills and the few studies conducted on the inter-relationship of language and social skills in pediatric and adult epilepsy. The paper concludes with suggested future research and clinical directions that will enhance early identification and treatment of epilepsy patients at risk for impaired language and social skills.

    Stroke and epilepsy are two of the most common neurological disorders and share a complicated relationship. It is well established that stroke is one of the most important causes of epilepsy, particularly new-onset epilepsy among the elderly. However, post-epilepsy stroke has been overlooked. In recent years, it has been demonstrated that epilepsy patients have increased risk and mortality from stroke when compared with the general population. Additionally, it was proposed that post-epilepsy stroke might be associated with antiepileptic drugs (AEDs), epileptic seizures and the lifestyle of epileptic patients. Here, we comprehensively review the epidemiology, causes and interventions for post-epilepsy stroke.

    1984-01-01

    The glucose metabolism of interictal epileptic foci in human brains were analyzed by positron emission tomography. The seizure patterns of 29 epileptic patients were as follows; complex partial 13 cases, elementary partial 9 cases, and generalized 7 cases. 11 C was produced by a JSW medical cyclotron BC105 and was randomly tagged to glucose prepared by photosynthesis. Data sampling by PET was started 15 minutes after peroral administration of 11 C-glucose to the patients. Three slices with 1.75 cm distance were obtained by a single scanning. In temporal lobe epilepsy, three slices were selected as 2.0 cm, 3.75 cm and 5.5 cm above orbitomeatal line. The basal ganglia were scanned 4.5 -- 5.0 cm and the motor and sensory strips were 5.0 -- 9.0 cm above OML. The glucose metabolic rate was expressed with color scales and qualitatively estimated. The results disclosed an obvious hypometabolic zone around a focus area in 22 cases (76%) out of the 29 subjects. This hypometabolic zone was observed in 12 cases (92%) of 13 complex partial, 9 cases (78%) of 9 elementary partial, and 3 cases (43%) of 7 generalized seizure patterns. In temporal lobe epilepsy, the location of the hypometabolic zone was different according to the clinical symptoms. The patients with automatism, pseudoabsence, autonomic, and emotional symptoms had its foci in the mesial portion of the temporal lobe. On the other hand, the patients with psychical seizure revealed its low metabolic area in the lateral temporal cortex. In the elementary partial epilepsy, the hypoactive zones were observed in the motor, sensory, and visual cortical area in accordance with the clinical symptoms. Very interestingly, an explicit cortical focus was discovered in two cases of the generalized epilepsy. In these cases the mechanism of secondary generalization was supposed to proceed in the expression of their clinical symptoms. In one Lennox-Gastaut case, a unilateral temporal lobe was involved as the seizure focus. (J.P.N.)

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.

    Although differences in illness perceptions between neurologists and patients with epilepsy or psychogenic nonepileptic seizures (PNES) are likely to be clinically relevant, this is the first study to attempt a direct comparison. In addition, this study compares the illness perceptions of patients with epilepsy with those of patients with PNES. Thirty-four patients with epilepsy, 40 patients with PNES, and 45 neurologists were recruited. All patient participants completed versions of the illness perception questionnaire revised (IPQ-R) adapted for epileptic or nonepileptic seizure disorders, single-item symptom attribution question (SAQ), Hospital Anxiety and Depression Scale (HADS), Quality of Life in Epilepsy-31 (QOLIE-31), and Liverpool Seizure Severity Scale (LSSS). Participating neurologists completed two versions of the IPQ-R and two SAQs for epileptic and nonepileptic seizure disorders. Differences in illness perceptions between patients with epilepsy and patients with PNES were minor compared to those between patients with either seizure disorder and neurologists. Neurologists considered both seizure disorders more treatable and more amenable to personal control than did the patients themselves. Neurologists had much more polarized views of the etiology of both conditions; whereas patients mostly considered the causes of their seizure disorders as partially "physical" and partially "psychological," neurologists perceived epilepsy as an essentially "physical" and PNES as a clearly "psychological" problem. There are considerable differences between the illness perceptions of patients with seizure disorders and their doctors, which could represent barriers to successful clinical management. In particular, a discrepancy between neurologists' and patients' beliefs about the personal control that patients may be able to exert over PNES could contribute to the confusion or anger some patients report after the diagnosis has been explained to them.

    Full Text Available Until recently, genetic generalized epilepsy (GGE was believed to be of presumed genetic etiology with no identifiable genetic mutation or demonstrable epigenetic abnormality. A wide range of epileptic disorders has clue for an inherited susceptibility. Monogenic disorders associated with epilepsy mental retardation and structural brain lesion typified by heterotopias, tuberous sclerosis, and progressive myoclonus epilepsies account for about 1% of epilepsies. This review focuses on the role of genetic mutations and epigenetic rearrangements in the pathophysiologic mechanism of GGE. To achieve this; PubMed, EMBASE, and Google Scholar were systematically and comprehensively searched using keywords (“epilepsy” “juvenile myoclonic epilepsy (JME,” “typical absences,” “idiopathic generalized epilepsy,” “JME,” “juvenile absence epilepsy,” “childhood absence epilepsy” “generalized tonic-clonic seizure” “GTCS”. Most GGE has evidence of underlying genetic inheritance. Recent animal studies have shown that early detection and treatment of genetic generalized epilepsies can alter the phenotypic presentation in rodents. These findings suggest a critical period in epileptogenesis, during which spike-and-wave seizures can be suppressed, leading to chronic changes in the brain (epileptogenesis and the preceding dysfunctions may, therefore, be targeted using therapeutic approaches that may either delay or inhibit the transition to active epileptic attack. The interplay between genetic mutations and epigenetic rearrangements play important roles in the development of GCE and that this process, especially at crucial developmental periods, is very susceptible to environmental modulations.

    Voice disorders affect adults and children and have different causes in different age groups. The aim of the study is to present the etiology and diagnosis dysphonia in a large population of patients with this voice disorder.for dysphonia of a large population of dysphonic patients. We evaluated 2019 patients with dysphonia who attended the Voice Disease ambulatories of a university hospital. Parameters assessed were age, gender, profession, associated symptoms, smoking, and videolaryngoscopy diagnoses. Of the 2019 patients with dysphonia who were included in this study, 786 were male (38.93%) and 1233 were female (61.07). The age groups were as follows: 1-6 years (n = 100); 7-12 years (n = 187); 13-18 years (n = 92); 19-39 years (n = 494); 41-60 years (n = 811); and >60 years (n = 335). Symptoms associated with dysphonia were vocal overuse (n = 677), gastroesophageal symptoms (n = 535), and nasosinusal symptoms (n = 497). The predominant professions of the patients were domestic workers, students, and teachers. Smoking was reported by 13.6% patients. With regard to the etiology of dysphonia, in children (1-18 years old), nodules (n = 225; 59.3%), cysts (n = 39; 10.3%), and acute laryngitis (n = 26; 6.8%) prevailed. In adults (19-60 years old), functional dysphonia (n = 268; 20.5%), acid laryngitis (n = 164; 12.5%), and vocal polyps (n = 156; 12%) predominated. In patients older than 60 years, presbyphonia (n = 89; 26.5%), functional dysphonia (n = 59; 17.6%), and Reinke's edema (n = 48; 14%) predominated. In this population of 2019 patients with dysphonia, adults and women were predominant. Dysphonia had different etiologies in the age groups studied. Nodules and cysts were predominant in children, functional dysphonia and reflux in adults, and presbyphonia and Reinke's edema in the elderly. Copyright © 2016 The Voice Foundation.

    Social bonds are at the center of our daily living and are an essential determinant of our quality of life. In people with epilepsy, numerous factors can impede cognitive and affective functions necessary for smooth social interactions. Psychological and psychiatric complications are common in epilepsy and may hinder the processing of social information. In addition, neuropsychological deficits such as slowed processing speed, memory loss or attentional difficulties may interfere with enjoyable reciprocity of social interactions. We consider societal, psychological, and neuropsychological aspects of social life with particular emphasis on socio-cognitive functions in temporal lobe epilepsy. Deficits in emotion recognition and theory of mind, two main aspects of social cognition, are frequently observed in individuals with mesial temporal lobe epilepsy. Results from behavioural studies targeting these functions will be presented with a focus on their relevance for patients' daily life. Furthermore, we will broach the issue of pitfalls in current diagnostic tools and potential directions for future research. By giving a broad overview of individual and interpersonal determinants of social functioning in epilepsy, we hope to provide a basis for future research to establish social cognition as a key component in the comprehensive assessment and care of those with epilepsy.

    Most individuals with epilepsy will respond to pharmacologic treatment; however, approximately 20-30% will develop medically refractory epilepsy. Cognitive side effects of antiepileptic drugs are common and can negatively affect tolerability, compliance, and long-term retention of the treatment. Ketogenic diet is an effective and well-tolerated treatment for these children with refractory epilepsy without any negative effect on cognition or behavior. To review the current state of experimental and clinical data concerning the neuroprotective and cognitive effects of the ketogenic diet in both humans and animals. In different animal models, with or without epilepsy, the ketogenic diet seems to have neuroprotective and mood-stabilizing effects. In the observational studies in pediatric epilepsy, improvements during treatment with the ketogenic diet are reported in behavior and cognitive function, particularly with respect to attention, alertness, activity level, socialization, and sleep quality. One randomized controlled trial in patients with pediatric refractory epilepsy showed a mood and cognitive activation during ketogenic diet treatment. Ketogenic diet shows a positive impact on behavioral and cognitive functioning in children and adolescents with refractory epilepsy. More specifically, an improvement is observed in mood, sustained attention, and social interaction.

  13. Epilepsy care in general practice.

    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.

    The results of the clinical neurological investigation were compared with those of electroencephalography (EEG) and computed tomography (CT) in 64 patients suffering from verified posttraumatic epilepsy. Only 18 patients (28%) showed central neurological features with corresponding focal disorders on CT (15 cases) and EEG (11 cases). EEG results were normal in 12 cases (19%), CT in 14 cases (22%). The combined application of both methods led to positive results in 94% on the part of at least one accessory examination. The clinical neurological investigation as well as the EEG and CT were normal in only 3 cases, although the traumatic etiology of epilepsy was beyond doubt. In addition to the clinical neurological investigation, EEG and CT are most important accessory examinations for the diagnosis and followup studies in cases of posttraumatic epilepsy. (orig.) [de

  15. Does abnormal glycogen structure contribute to increased susceptibility to seizures in epilepsy?

    Science.gov (United States)

    DiNuzzo, Mauro; Mangia, Silvia; Maraviglia, Bruno; Giove, Federico

    2015-02-01

    Epilepsy is a family of brain disorders with a largely unknown etiology and high percentage of pharmacoresistance. The clinical manifestations of epilepsy are seizures, which originate from aberrant neuronal synchronization and hyperexcitability. Reactive astrocytosis, a hallmark of the epileptic tissue, develops into loss-of-function of glutamine synthetase, impairment of glutamate-glutamine cycle and increase in extracellular and astrocytic glutamate concentration. Here, we argue that chronically elevated intracellular glutamate level in astrocytes is instrumental to alterations in the metabolism of glycogen and leads to the synthesis of polyglucosans. Unaccessibility of glycogen-degrading enzymes to these insoluble molecules compromises the glycogenolysis-dependent reuptake of extracellular K(+) by astrocytes, thereby leading to increased extracellular K(+) and associated membrane depolarization. Based on current knowledge, we propose that the deterioration in structural homogeneity of glycogen particles is relevant to disruption of brain K(+) homeostasis and increased susceptibility to seizures in epilepsy.

  16. SPECT in Focal Epilepsies

    Directory of Open Access Journals (Sweden)

    Roderick Duncan

    2000-01-01

    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.

  17. Epilepsy in Dostoevsky's novels.

    Voskuil, Piet H A

    2013-01-01

    Fyodor Mikhailovich Dostoevsky (1821-1881) suffered from epilepsy. Some type of psychopathology can be found in about 25% of the characters of his novels. Some of them have seizures. In at least five of them Dostoevsky clearly intends them to have epilepsy. Others are more likely to be created as people with hysteria or sometimes, for instance, possession. In this essay an inventory is given by more or less comprehensive quotes of different types of seizures in five novels. The seizures are named in the novels with a varying vocabulary based on the concepts of nosology in the 19th century, the knowledge of Dostoevsky of these concepts, his own experiences, and problems in translation and transliteration. In the discussion, analysis of the role these factors played in the understanding of what Dostoevsky really expressed is given attention. Special attention is given to the so-called ecstatic aura. This element of focal epileptic seizures is so rare that in the past the description of it raised doubts on its existence as such and therefore the embellishment by Dostoevsky, describing his own experience and/or that of his epileptic characters Kirillov and Myshkin. The consequence of this analytic approach, however, should not be losing one's amazement of the genius polyphonic creativity of Dostoevsky to integrate so many profound aspects of the human and especially the Russian soul in the characters of his novels.

    Bonello, M; Michael, B D; Solomon, T

    2015-06-01

    A wide range of infections of the central nervous system are responsible for both acute seizures and epilepsy. The pathogenesis and clinical semiology of the seizure disorders vary widely between the infective pathogens. The exact mechanisms underlying this are poorly understood, but appear, at least in part, to relate to the pathogen; the degree of cortical involvement; delays in treatment; and the host inflammatory response. The treatment of infective causes of seizures involves both symptomatic treatment with antiepileptic drugs and direct treatment of the underlying condition. In many cases, early treatment of the infection may affect the prognosis of the epilepsy syndrome. The greatest burden of acute and long-term infection-related seizures occurs in resource-poor settings, where both clinical and research facilities are often lacking to manage such patients adequately. Nevertheless, education programs may go a long way toward addressing the stigma, leading to improved diagnosis, management, and ultimately to better quality of life.

    Latkany, Robert

    2008-07-01

    Until recently, the cause of dry eye syndrome was uncertain and the treatment was palliative. Since discovering that dry eyes are caused by inflammation, there has been an abundance of research focusing on anti-inflammatory therapies, other contributing causes, and better diagnostic testing. This review summarizes some of the interesting published research on ocular surface disease over the past year. The definition of dry eye now highlights the omnipresent symptom of blurry vision. The re-evaluation of ocular surface staining, tear meniscus height, and visual change will allow for a better diagnosis and understanding of dry eyes. Punctal plugs, and oral and topical anti-inflammatory use will strengthen our arsenal against ocular surface disease. Major progress has occurred in the past few years in gaining a better understanding of the etiology of dry eye syndrome, which will inevitably lead to more effective therapeutic options.

    2016-04-01

    The aim of this qualitative study was to explore the challenges that parents of children with epilepsy experienced when engaging in dialog with their child about epilepsy and epilepsy-related issues. Using a qualitative exploratory approach, interviews were conducted with 34 parents of children with epilepsy (aged 6-16 years), consisting of 27 mothers and 7 fathers. Data were transcribed verbatim and thematically analyzed. Findings revealed five main themes: normalizing epilepsy, the invisibility of epilepsy, information concealment, fear of misinforming the child, and difficulty in discussing particular epilepsy-related issues. Many of the communicative challenges experienced by parents impacted on their ability to engage openly in parent-child dialog about epilepsy in the home. Parents face specific challenges when choosing to communicate with their child about epilepsy, relating to creating a sense of normality, reducing fear of causing their child worry, and having a lack of epilepsy-related knowledge. Healthcare professionals who work closely with families living with epilepsy should remain mindful of the importance of discussing family communication surrounding epilepsy and the challenges parents of children with epilepsy face when talking about epilepsy within the home.

    Full Text Available Objective: Psoas abscess (PA is a rare infection disease, which is difficult to diagnose. In the present study, we aimed to evaluate etiological factors and treatment results of patients with PA. Methods: Files of 20 patients who were diagnosed as PA between December 2006 and January 2013, were retrospectively analyzed. Patient’s whose data were entirely reached and diagnosed by Ultrasonography and/or Computed Tomography as an exact PA were included to the study. Results: The mean age of the 20 patients was 48.8 (range 17-82 year, and 6 of them were female and remaining were male. Psoas abscess were on the right side in 12 patients (60%, on the left side in seven patients (35%, and bilateral in one (5%. According to data records four patients had Diabetes Mellitus (20%, two had Hypertension (10%, one had cerebrovascular disease (5%, one had tuberculosis (5%, one had hyperthyroidism (5%, one had mental retardation (5%, and one had paraplegia (5%. Six case (30% were diagnosed as a primary psoas abscess (pPA, sPA and remaining (n=14, %70 were diagnosed as secondary. Percutaneous drainage was performed to 13 patients (65% and exploration was performed to three patients (15% as a treatment modality. Remaining four patients (20% were followed by medical treatment. Conclusion: Psoas abscess is rare and have variable and non-specific clinical characteristic, which may lead to difficulty in diagnosis. In developed and developing countries, it has been reported that the most common causes of sPA are Pott's disease, and Crohn's disease, also it should be taken into account that open surgery and urinary tract stone disease can receive a significant portion of the etiological factors.

    Rapid advances in genetic research and increased use of genetic testing have increased the emphasis on genetic causes of epilepsy in patient encounters. Research in other disorders suggests that genetic causal attributions can influence patients' psychological responses and coping strategies, but little is known about how epilepsy patients and their relatives will respond to genetic attributions of epilepsy. We investigated the possibility that among members of families containing multiple individuals with epilepsy, depression, the most frequent psychiatric comorbidity in the epilepsies, might be related to the perception that epilepsy has a genetic cause. A self-administered survey was completed by 417 individuals in 104 families averaging 4 individuals with epilepsy per family. Current depression was measured with the Patient Health Questionnaire. Genetic causal attribution was assessed by three questions addressing the following: perceived likelihood of having an epilepsy-related mutation, perceived role of genetics in causing epilepsy in the family, and (in individuals with epilepsy) perceived influence of genetics in causing the individual's epilepsy. Relatives without epilepsy were asked about their perceived chance of developing epilepsy in the future, compared with the average person. Prevalence of current depression was 14.8% in 182 individuals with epilepsy, 6.5% in 184 biologic relatives without epilepsy, and 3.9% in 51 individuals married into the families. Among individuals with epilepsy, depression was unrelated to genetic attribution. Among biologic relatives without epilepsy, however, prevalence of depression increased with increasing perceived chance of having an epilepsy-related mutation (p = 0.02). This association was not mediated by perceived future epilepsy risk among relatives without epilepsy. Depression is associated with perceived likelihood of carrying an epilepsy-related mutation among individuals without epilepsy in families containing

    Antithyroid antibodies (Abs) are associated with epilepsy in steroid-responsive encephalopathy, but have been rarely studied in unselected epilepsy patients. This study aimed to characterize the prevalence and associated factors of antithyroid Abs and other auto-Abs in adult patients with epilepsy.Epilepsy patients without autoimmune disorders were surveyed for antinuclear antibody (ANA), anti-β2 glycoprotein 1 antibody (aβ2GP1), anticardiolipin IgG Ab, antimicrosomal antibody (AMA), antithyroglobulin antibody (ATA), and thyroid function test.Of 319 patients, 75 (23.5%) were positive for at least 1 Ab. The most common Ab was anticardiolipin antibody (aCL) (30/319, 9.4%), followed by AMA (24/319, 7.5%), ANA (18/319, 5.6%), aβ2GP1 (18/319, 6.5%), and ATA (6/319, 3.25%). Antimicrosomal Abs were significantly more frequent in patients who were female, older at disease onset, older at the time of study, and had unknown seizure etiology. The presence of aCL was significantly associated with more frequent seizures. Most patients with antithyroid Ab were female and had focal seizures with unknown etiology.The association of different auto-Abs with different factors suggests that they may have different roles in adult patients with epilepsy. Recurrent seizures and certain antiepileptic medications may cause the production of aCL. The role of antithyroid Abs in adult focal epilepsy with unknown cause, especially in females, warrants further evaluation because of the potential implications on treatment.

    2007-09-01

    The etiologic profile and possible predictors of etiology in children with spastic quadriplegia were assessed in a consecutive cohort of children with this motor impairment. Medical records from a single pediatric neurology practice over a 14-year interval were retrospectively and systematically reviewed. Variables comprised possible demographic, prenatal, perinatal, and postnatal risk factors. Of the 99 patients included in the study, 39 were premature (quadriplegia was 83%, with differing underlying etiologies depending on gestational age. These results should help guide physicians in investigating possible underlying etiologies in patients with spastic quadriplegia.

    Non-traumatic coma (NTC) is a serious condition requiring swift medical or surgical decision making upon arrival at the emergency department. Knowledge of the most frequent etiologies of NTC and associated mortality might improve the management of these patients. Here, we present the results of a systematic literature search on the etiologies and prognosis of NTC. Two reviewers independently performed a systematic literature search in the Pubmed, Embase and Cochrane databases with subsequent reference and citation checking. Inclusion criteria were retrospective or prospective observational studies on NTC, which reported on etiologies and prognostic information of patients admitted to the emergency department or intensive care unit. Eventually, 14 studies with enough data on NTC, were selected for this systematic literature review. The most common causes of NTC were stroke (6-54%), post-anoxic coma (3-42%), poisoning (coma (54-89%) and lowest for poisoning (0-39%) and epilepsy (0-10%). NTC represents a challenge to the emergency and the critical care physicians with an important mortality and moderate-severe disability rate. Even though, included studies were very heterogeneous, the most common causes of NTC are stroke, post anoxic, poisoning and various metabolic etiologies. The best outcome is achieved for patients with poisoning and epilepsy, while the worst outcome was seen in patients with stroke and post-anoxic coma. Adequate knowledge of the most common causes of NTC and prioritizing the causes by mortality ensures a swift and adequate work-up in diagnosis of NTC and may improve outcome.

    It is a general rule today, after a relevant diagnostics of an epilepsy, to start a monotherapy treatment, depending on a kind of a seizure, a life age and a general health condition. First line of monotherapy epilepsy drugs remain carbamazapine and sodium valproat. New drugs that are being introduced are: felbamat, gabapentin, lamotrigin, oxcarbazepin, tiagabin, topiramat, vigabatin and zanisamid. These are commonly used as add-on therapy, or as an addition for previously used antiepileptic. Their indicated areas are complex resistant partial seizures with or without generalization. Attention should be paid on proper dosage, interactions and toxicity. Regardless on the new epileptic era, according to reports of International League against epilepsy, most of the patients do not receive the drug that is the most appropriate for them concerning the price (cost-benefit). Neurosurgical methods in epilepsy treatment are: selective amygdalo-hyppocampotomy, temporal lobotomy, subpial resection, hemispherectomy, corpus callosotomy, removal of lesions like tumors or cysts provide encouraging results in reduction of epileptic seizures that can be followed by reduction of drug therapy. N. vagus stimulation is being wider introduced in resident epileptics. Treatment of epilepsy in women requires an approach to sexuality, conception, pregnancy, introduction of medicaments, antiepileptic terratogenity, contraception, motherhood and menopause. A special significance of modern approach to epilepsy is in treatment of elderly who have cerebrovascular and neurodegenerative disease as a cause of seizures. A complex treatment of epilepsy using pharmacological and neurosurgical approach requires supportive psychotherapy, socio-therapy, the work with a family, education about epilepsy and living a life with more quality having one.

    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)

    Epilepsy, a complex spectrum of disorders, affects about 2.9 million people in the U.S. Similar to other chronic disorders, people with epilepsy face challenges related to management of the disorder, its treatment, co-occurring depression, disability, social disadvantages, and stigma. Two national conferences on public health and epilepsy (1997, 2003) and a 2012 IOM report on the public health dimensions of epilepsy highlighted important knowledge gaps and emphasized the need for evidence-based, scalable epilepsy self-management programs. The Centers for Disease Control and Prevention translated recommendations on self-management research and dissemination into an applied research program through the Prevention Research Centers Managing Epilepsy Well (MEW) Network. MEW Network objectives are to advance epilepsy self-management research by developing effective interventions that can be broadly disseminated for use in people's homes, healthcare providers' offices, or in community settings. The aim of this report is to provide an update on the MEW Network research pipeline, which spans efficacy, effectiveness, and dissemination. Many of the interventions use e-health strategies to eliminate barriers to care (e.g., lack of transportation, functional limitations, and stigma). Strengths of this mature research network are the culture of collaboration, community-based partnerships, e-health methods, and its portfolio of prevention activities, which range from efficacy studies engaging hard-to-reach groups, to initiatives focused on provider training and knowledge translation. The MEW Network works with organizations across the country to expand its capacity, help leverage funding and other resources, and enhance the development, dissemination, and sustainability of MEW Network programs and tools. Guided by national initiatives targeting chronic disease or epilepsy burden since 2007, the MEW Network has been responsible for more than 43 scientific journal articles, two

    Seizures that are resistant to standard medications remain a major clinical problem. One underutilized option for patients with medication-resistant seizures is the high-fat, low-carbohydrate ketogenic diet. The diet received its name based on the observation that patients consuming this diet produce ketone bodies (e.g., acetoacetate, β-hydroxybutyrate, and acetone). Although the exact mechanisms of the diet are unknown, ketone bodies have been hypothesized to contribute to the anticonvulsant and antiepileptic effects. In this review, anticonvulsant properties of ketone bodies and the ketogenic diet are discussed (including GABAergic and glutamatergic effects). Because of the importance of ketone body metabolism in the early stages of life, the effects of ketone bodies on developing neurons in vitro also are discussed. Understanding how ketone bodies exert their effects will help optimize their use in treating epilepsy and other neurological disorders. © 2012 The Authors.

  13. Vigilance, sleep and epilepsy.

    The correlations between vigilance and epilepsy are manifold. Nearly all epileptic seizures cause a diminution of vigilance extending to unconsciousness. Many of the influences triggering or inhibiting epileptic seizures produce alterations of vigilance or are produced by them. Nearly all chemical influences more or less cause diminution of vigilance. The enhancement of vigilance may inhibit seizures. Decreasing vigilance may act vice versa. As a means to enhance vigilance afferent stimuli are able to trigger seizures. This may be accomplished when singular or rhythmic stimulation of afferents gets the already excited neuronal system oscillating. This principle is also responsible for the strong correlation between triggering of seizures and the sleep/waking cycle with its different grades of neuronal synchronization. On the other hand, inhibition of seizures is possible by a continuously applied stimulation load, which may disturb the increasing excitatory oscillation. Also, conditioning may trigger or inhibit seizures. But the EEG biofeedback only is used to decrease abnormal neuronal activity.

    1995-01-01

    In an retrospective uncontrolled long-term study in 30 children with intractable epilepsy, it was found that treatment with vigabatrin resulted in a seizure reduction of more than 50% at 1-year follow-up in 40% of the children. The responders were all children with partial seizures. Side effects...... were mild and did not lead to discontinuation of the drug. Increased numbers of seizures were seen in three cases. A moderate weight increase was seen in 27% of the children. At 5-year follow-up 7 children (23%) still maintained a seizure reduction of more than 50%. Trials of monotherapy in three...... seizure-free patients were unsuccessful. No further side effects were observed. A study of evoked potentials in 12 children showed no alteration in latency and amplitudes of VEP following treatment with vigabatrin. Our results show that in children vigabatrin seems to have a stable effect even though...

    Nine patients who had epileptic attacks while playing computer games were studied in the laboratory. Patients had an EEG recorded as well as their response to intermittent photic stimulation (IPS) at flash rates of 1-60 fps. In addition, pattern sensitivity was assessed in all patients by a gratings pattern. Only 2 patients had no previous history of convulsions, and only 2 had a normal basic EEG. All but 1 were sensitive to IPS, and all but 1 were pattern sensitive. Most patients were male, but although this appears to conflict with previously published literature results regarding the sex ratio in photosensitivity, it was due to the male predominance of video game usage. We compared our results with those reported in the literature. Diagnosing video game epilepsy requires performing an EEG with IPS and pattern stimulation. We propose a standard method of testing.

    2003-01-01

    Full Text Available The understanding of erectile physiology has improved the prompt diagnosis and treatment of priapism. Priapism is defined as prolonged and persistent erection of the penis without sexual stimulation and failure to subside despite orgasm. Numerous etiologies of this condition are considered. Among others a disturbed detumescence mechanism, which may due to excess release of contractile neurotransmitters, obstruction of draining venules, malfunction of the intrinsic detumescence mechanism or prolonged relaxation of intracavernosal smooth muscle are postulated. Treatment of priapism varies from a conservative medical to a drastic surgical approach. Two main types of priapism; veno-occlusive low flow (ischemic and arterial high flow (non-ischemic, must be distinguished to choose the correct treatment option for each type. Patient history, physical examination, penile hemodynamics and corporeal metabolic blood quality provides distinction between a static or dynamic pathology. Priapism can be treated effectively with intracavernous vasoconstrictive agents or surgical shunting. Alternative options, such as intracavernous injection of methylene blue (MB or selective penile arterial embolization (SPEA, for the management of high and low flow priapism are described and a survey on current treatment modalities is given.

  17. [New etiological concepts in uveitis].

    Bodaghi, B

    2005-05-01

    Uveitis remains an important cause of visual impairment, particularly in young patients. Idiopathic forms of intraocular inflammation should no longer be regarded as a presumed clinical entity, and the ophthalmologist must reconsider the specific etiology of primary uveitis when the clinical examination does not yield a definitive diagnosis or when the course of the disease on corticosteroids remains atypical. Laboratory tests based on serum analysis have limited value and should not be considered as diagnostic proof in different clinical presentations. The diagnostic management of infectious uveitis has been greatly improved by the use of molecular techniques applied to ocular fluids and tissues. Polymerase chain reaction (PCR) technology is a powerful tool that should be proposed in atypical cases of uveitis or retinitis of unclear but potentially infectious origin. This strategy is a major step before using unconventional and new immunomodulatory agents such as anti-TNF-alpha molecules. Under strict experimental conditions including adequate testing to rule out a possible contamination, PCR and its variants have changed our practical approach to intraocular inflammatory disorders and have provided new details for the understanding of infectious uveitis. The concept of pathogen-induced intraocular inflammation can be revisited in the light of molecular data obtained after anterior chamber paracentesis or diagnostic vitrectomy.

    Intellectual disability (ID) is a prevailing neurodevelopmental condition associated with impaired cognitive and adaptive behaviors. Many chromatin-modifying enzymes and other epigenetic regulators have been genetically associated with ID disorders (IDDs). Here we review how alterations in the function of histone modifiers, chromatin remodelers, and methyl-DNA binding proteins contribute to neurodevelopmental defects and altered brain plasticity. We also discuss how progress in human genetics has led to the generation of mouse models that unveil the molecular etiology of ID, and outline the direction in which this field is moving to identify therapeutic strategies for IDDs. Importantly, because the chromatin regulators linked to IDDs often target common downstream genes and cellular processes, the impact of research in individual syndromes goes well beyond each syndrome and can also contribute to the understanding and therapy of other IDDs. Furthermore, the investigation of these disorders helps us to understand the role of chromatin regulators in brain development, plasticity, and gene expression, thereby answering fundamental questions in neurobiology.

    The objective of the study was to assess common practice in pediatric epilepsy surgery in Italy between 2008 and 2014. A survey was conducted among nine Italian epilepsy surgery centers to collect information on presurgical and postsurgical evaluation protocols, volumes and types of surgical interventions, and etiologies and seizure outcomes in pediatric epilepsy surgery between 2008 and 2014. Retrospective data on 527 surgical procedures were collected. The most frequent surgical approaches were temporal lobe resections and disconnections (133, 25.2%) and extratemporal lesionectomies (128, 24.3%); the most frequent etiologies were FCD II (107, 20.3%) and glioneuronal tumors (105, 19.9%). Volumes of surgeries increased over time independently from the age at surgery and the epilepsy surgery center. Engel class I was achieved in 73.6% of patients (range: 54.8 to 91.7%), with no significant changes between 2008 and 2014. Univariate analyses showed a decrease in the proportion of temporal resections and tumors and an increase in the proportion of FCDII, while multivariate analyses revealed an increase in the proportion of extratemporal surgeries over time. A higher proportion of temporal surgeries and tumors and a lower proportion of extratemporal and multilobar surgeries and of FCD were observed in low (epilepsy surgery in Italy between 2008 and 2014, associated with a stable seizure outcome.

    Animal models have provided a wealth of information on mechanisms of epileptogenesis and comorbidogenesis, and have significantly advanced our ability to investigate the potential of new therapies. Processes implicating brain inflammation have been increasingly observed in epilepsy research. Herein we discuss the progress on animal models of epilepsy and comorbidities that inform us on the potential role of inflammation in epileptogenesis and comorbidity pathogenesis in rodent models of West syndrome and the Theiler's murine encephalomyelitis virus (TMEV) mouse model of viral encephalitis-induced epilepsy. Rat models of infantile spasms were generated in rat pups after right intracerebral injections of proinflammatory compounds (lipopolysaccharides with or without doxorubicin, or cytokines) and were longitudinally monitored for epileptic spasms and neurodevelopmental and cognitive deficits. Anti-inflammatory treatments were tested after the onset of spasms. The TMEV mouse model was induced with intracerebral administration of TMEV and prospective monitoring for handling-induced seizures or seizure susceptibility, as well as long-term evaluations of behavioral comorbidities of epilepsy. Inflammatory processes are evident in both models and are implicated in the pathogenesis of the observed seizures and comorbidities. A common feature of these models, based on the data so far available, is their pharmacoresistant profile. The presented data support the role of inflammatory pathways in epileptogenesis and comorbidities in two distinct epilepsy models. Pharmacoresistance is a common feature of both inflammation-based models. Utilization of these models may facilitate the identification of age-specific, syndrome- or etiology-specific therapies for the epilepsies and attendant comorbidities, including the drug-resistant forms.

    Full Text Available Comorbidities are often associated with chronic neurological diseases, such as headache and epilepsy. OBJECTIVES: To identify comorbidities associated with epilepsy and headaches, and to determine possible drug interactions. METHODS: A standardized questionnaire with information about type of epilepsy/headache, medical history, and medication was administered to 80 adult subjects (40 with epilepsy and 40 with chronic headache. RESULTS: Patients with epilepsy had an average of two comorbidities and those with headache of three. For both groups, hypertension was the most prevalent. On average, patients with epilepsy were taking two antiepileptic medications and those with headache were taking only one prophylactic medication. Regarding concomitant medications, patients with epilepsy were in use, on average, of one drug and patients with headache of two. CONCLUSIONS: Patients with chronic neurological diseases, such as epilepsy and headaches, have a high number of comorbidities and they use many medications. This may contribute to poor adherence and interactions between different medications.

    Full Text Available Problems related to pregnancy and birth defects in the baby are major concerns for women with epilepsy. Hardly any data from this country is available in this regards to provide factual information to people with epilepsy. This study was undertaken to survey the outcome of pregnancies in women with epilepsy in this part of the country. Women with epilepsy (20to55 year of age who had attended this institute between March 1997 and march 1997 were sent a questionnaire by post regarding their martial status, reproductive history and outcome of pregnancies including any birth defects in their children. The data on clinical aspects and treatment were extracted from their medical records. 184 women (mean age 28.5 + 8 years were included in this study. 108 (58.7% of them were married. Women with epilepsy had three times higher rate of abortions (24.1% than general population(8%. Their mean family size (1.6 was lower than that is Kerala State (2.3. The proportion of women without children (13.9% was also higher than that for the state (9.8%. The frequency of birth defects among their children was twice (4% that in the community (2%. Women taking sodium valproate had higher frequency of birth defects in their children (15% as compared to other drugs but this was not statistically significant. There is a tendency for lower fertility among women with epilepsy. There is a slight increase in the frequency of birth defects among children born to mothers with epilepsy.

    Full Text Available Chronic urticaria is defined as a skin disease with central induration (wheal and erythema formation around it (flare that appears at least twice a week and remains at least for 6 weeks continually. The incidence of urticaria in children is about 0.1-3%. Most cases of chronic urticaria occur in children between 6-11 years. Autoimmune and allergy immaturity is one of the reasons of lower incidence of chronic urticaria in younger children. Quality of life impairment in children with urticaria has been known to be similar to diseases with severe atopic dermatitis, epilepsy, diabetes mellitus and asthma. There are several causes for chronic urticaria in children in different reports. In most of cases the known etiologic agents are varies from 21 to 83%. Overall, infectious causes of chronic urticaria in children are more common and obvious than other in adults .In most cases, the cause of chronic urticaria are idiopathic or autoimmune. Urticaria severity divided to mild, moderate and severe was based on the number of wheals and severity of pruritus. Diagnosis of chronic urticaria is based on a good history and physical examination. The treatment of chronic urticaria is a patient education that is to remove the triggering and aggravating agents, resolving and treating of the known disease and the use of various medicines based on the history and clinical findings. The first medical therapeutics lines in children are anti-histamines, beta-blocker H1 and new generation of non-sedating agents.

  11. Thermography Examination of Abdominal Area Skin Temperatures in Individuals With and Without Focal-Onset Epilepsy.

    Science.gov (United States)

    King, Hollis H; Cayce, Charles Thomas; Herrin, Jeph

    Early osteopathic theory and practice, and the work of the medical intuitive Edgar Cayce suggested that the abdominal areas of individuals with epilepsy would manifest "cold spots." The etiology for this phenomenon was thought to be abdominal adhesions caused by inflammation and viscero-somatic reflexes caused by adhesions or injury to visceral or musculoskeletal system structures. Indeed, until that advent of electroencephalography in the 1930s, medical practice regarding epilepsy focused on abdominal neural and visceral structures. Following two hypotheses were formulated to evaluate any abdominal temperature phenomena: (1) an abdominal quadrant division analysis would find one or more quadrants "colder" in the focal-onset epilepsy group (ICD9-CM 345.4 and 345.5) compared to controls. (2) Total abdominal areas of individuals with focal-onset epilepsy wound be colder than a control group. Overall, 50 patients with the diagnosis of focal-onset epilepsy were recruited from the office of the Epilepsy Foundation of Florida and 50 control subjects with no history of epilepsy were recruited through advertising to the public. Under controlled room conditions all subjects had infrared thermographic images made and recorded by Med-Hot Model MH-731 FLIR equipment. There were no significant demographic difference between experimental patients and control subjects, though the control group tended to be younger and more often male; however, these were controlled for in all analyses. In the quadrant analysis, there were significant differences in that more epileptic patients had colder left upper abdominal quadrant temperatures than the control group (66.8% versus 44.9%; P = .030). In the total abdominal analysis, however, there were no significant differences. The results support the hypothesis that individuals with focal-onset epilepsy have colder abdominal areas. If substantiated in further research, present study results will require further examination of the mechanisms of

    Various PET studies, such as measurements of glucose, serotonin and oxygen metabolism, cerebral blood flow and receptor bindings are availabe for epilepsy. 18Fluoro-2-deoxyglucose (18F-FDG) PET imaging of brain glucose metabolism is a well established and widely available technique. Studies have demonstrated that the sensitivity of interictal FDG-PET is higher than interictal SPECT and similar to ictal SPECT for the lateralization and localization of epileptogenic foci in presurgical patients refractory to medical treatments who have noncontributory EEG and MRI. In addition to localizing epileptogenic focus, FDG-PET provide additional important information on the functional status of the rest of the brain. The main limitation of interictal FDG-PET is that it cannot precisely define the surgical margin as the area of hypometabolism usually extends beyond the epileptogenic zone. Various neurotransmitters (GABA, glutamate, opiates, serotonin, dopamine, acethylcholine, and adenosine) and receptor subtypes are involved in epilepsy. PET receptor imaging studies performed in limited centers help to understand the role of neurotransmitters in epileptogenesis, identify epileptic foci and investigate new treatment approaches. PET receptor imaging studies have demonstrated reduced 11C-flumazenil (GABAA-cBDZ) and 18F-MPPF (5-HT1A serotonin) and increased 11C-cerfentanil (mu opiate) and 11C-MeNTI (delta opiate) bindings in the area of seizure. 11C-flumazenil has been reported to be more sensitive than FDG-PET for identifying epileptic foci. The area of abnormality on GABAAcBDZ and opiate receptor images is usually smaller and more circumscribed than the area of hypometabolism on FDG images. Studies have demonstrated that 11C-alpha-methyl-L-tryptophan PET (to study synthesis of serotonin) can detect the epileptic focus within malformations of cortical development and helps in differentiating epileptogenic from non-epileptogenic tubers in patients with tuberous sclerosis complex

    2014-03-01

    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. Copyright © 2013 Elsevier Inc. All rights reserved.

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.

    In 1769, William Cullen introduced the word "urticaria" (transient edematous papules, plaque with itching). Urticaria affects 15-25% of people at least once in their life time. It is a clinical reaction pattern triggered by many factors causing the liberation of vasoactive substances such as histamine, prostaglandins and kinins. Urticaria is classified according to its duration into acute (6 weeks duration). Various clinical investigations may be initiated to diagnosis the cause. To evaluate the types of chronic urticaria with reference to etiology from history and investigations. A total of 150 patients with chronic urticaria of more than six weeks were studied. Autologous serum skin test (ASST) was performed after physical urticarias were excluded. Standard batteries of tests were performed after ASST in all patients; and other specific investigations were done where necessary. Skin prick test was done in idiopathic urticaria. The study sample consisted of 62 male and 88 female patients with a mean age of 21-40 years. About 50% of patients showed an ASST positive reaction, 3.9% were positive for antinuclear antibody (ANA), IgE titer was elevated in 37%, H. pylori antibodies was positive in 26.7%.

    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.

    In its 2010 report, the International League Against Epilepsy Commission on Classification and Terminology had made a number of changes to the organization, terminology, and classification of seizures and epilepsies. This study aims to test the usefulness of this revised classification scheme on children with epilepsies aged between 0 and 18 years old. Of 527 patients, 75.1% only had 1 type of seizure and the commonest was focal seizure (61.9%). A specific electroclinical syndrome diagnosis could be made in 27.5%. Only 2.1% had a distinctive constellation. In this cohort, 46.9% had an underlying structural, metabolic, or genetic etiology. Among the important causes were pre-/perinatal insults, malformation of cortical development, intracranial infections, and neurocutaneous syndromes. However, 23.5% of the patients in our cohort were classified as having "epilepsies of unknown cause." The revised classification scheme is generally useful for pediatric patients. To make it more inclusive and clinically meaningful, some local customizations are required.

    The concept of etiology is analyzed and the possibilities and limitations of deterministic, probabilistic, and fuzzy etiology are explored. Different kinds of formal structures for the relation of causation are introduced which enable us to explicate the notion of cause on qualitative, comparative, and quantitative levels. The conceptual framework developed is an approach to a theory of causality that may be useful in etiologic research, in building nosological systems, and in differential diagnosis, therapeutic decision-making, and controlled clinical trials. The bearings of the theory are exemplified by examining the current Chlamydia pneumoniae hypothesis on the incidence of myocardial infarction.

    Full Text Available Epilepsy’s overall prevalence in Colombia is 1.13%. Its prevalence in patients aged over 65 could be around 1.5%. Objective: describe demographic and clinical characteristics of patients older than 65 years of age with epilepsy. Materials and methods: A cross-sectional descriptive study was carried out in two high complexity hospitals in Bogotá, Colombia during 2005-2008. Demographic data were compiled and patients characterized regarding the type, frequency and diagnosis of seizures (based on ILAE classification, probable etiology, having a family background of epilepsy, and current pharmacological management. Results: 211 clinical histories were reviewed and 179 of them selected. Mean patient age was 75 (65-98 and average age at onset of epilepsy was 67.5 (7-93. 84% of the seizures were classified as being focal. The most frequently occurring diagnosis was symptomatic focal epilepsy (94.4%. 74 cases (41.3% had an etiological diagnosis. The most important cause was cerebrovascular disease (61 patients. First generation anti-epileptic drugs were the most used ones (99%. 81/104 patients were found not to be free from epileptic episodes. Conclusions: Most seizures have a partial beginning, resulting from symptomatic partial epilepsy as a consequence of a vascular lesion. Pharmacological treatment must be considered following the first seizure. Treatment with second generation anti-epileptic drugs such as Lamotrigine, Gabapentin, Levetiracetam and Topiramate must be begun for minimizing secondary effects and low doses must be maintained from the start of treatment. Costs may limit the use of the above antiepileptic drugs, in such cases Phenytoin and Carbamazepine may be used with extreme caution.

    Objective: To study the characteristics of the epileptics and the risk factors contributing to the development of epilepsy. Results: Majority of the subjects were single (77.84%), 1st born among their siblings (25.95%), belonged to low social class (50.63%), and unemployed(25.31%). The major risk factors were family history of illness (23.52%) and positive medical problem around birth (12.66%). The presence of family history of illness, positive medical problem around birth and advanced maternal age at birth were associated with early onset of epilepsy. Vulnerability for the epilepsy also increases among hospital deliveries. Conclusion: Although the present study has identified various risk factors, yet the results need to be further confirmed through case-control studies. (author)

    Full Text Available People with epilepsy are prone to be sedentary compared with the general population. The causes of inactivity are ignorance, prejudice, overprotection, fear and shame. There is no scientific evidence supporting a limitation of physical exercise in persons with epilepsy. The benefits of exercise in these patients are huge. Positive aspects are: physical conditioning, prevention of seizures, emotional wellbeing, social interaction, drug treatment adherence, osteoporosis prevention and better quality of life for patients and their families. Having in mind the individual characteristics, physical exercise should be prescribed and guided. Available evidence underlies the complementary therapeutic effects of physical activity with large positive results at a low cost. Sports or regular physical activity should be a standard indication for persons with epilepsy.

    The psychiatrist should be given also their share in the prevetion of epilepsy by means of raising the psychiatric culture of the society and teaching the population the principles of mental hygiene and psychoprophylaxia. The possibilities of psychiatry in prophylactic management of patients with developed epilepsy include: 1. Energetic measures for controlling attacks which has many psychoprophylactic aspects. 2. Prevention of psychotraumatizing situations leading to secondary neurotic, psychotic and other reactions and behaviour disorders of the type of homilopathy and sociopathy, 3. Counteracting the development of mental and social disability in epileptics. Treatment of epilepsy should be conducted from its very beginning in cooperation with psychiatrists and therapeutic psychologists. The probems of prophylaxis cannot be separated from prophylactic treatment, psychotherapy sociotherapy and rehabilitation.

    Full Text Available Most isolated episodes of apparent life-threatening events (ALTEs do not lead to the diagnosis of serious conditions, and their prognoses are generally benign. However, recurrent ALTEs are often associated with a risk of future serious adverse events and should be evaluated for appropriate management. Here we present ALTE case in which gastric volvulus associated gastroesophageal reflux disease was detected as an etiology initially, followed by the detection of epilepsy as another etiology. Clinicians should consider possibility of two or more etiologies in a single recurrent ALTE case.

    Full Text Available Background: In 1769, William Cullen introduced the word "urticaria" (transient edematous papules, plaque with itching. Urticaria affects 15-25% of people at least once in their life time. It is a clinical reaction pattern triggered by many factors causing the liberation of vasoactive substances such as histamine, prostaglandins and kinins. Urticaria is classified according to its duration into acute (< 6 weeks duration and chronic (>6 weeks duration. Various clinical investigations may be initiated to diagnosis the cause. Aims: To evaluate the types of chronic urticaria with reference to etiology from history and investigations . Materials and Methods: A total of 150 patients with chronic urticaria of more than six weeks were studied. Autologous serum skin test (ASST was performed after physical urticarias were excluded. Standard batteries of tests were performed after ASST in all patients; and other specific investigations were done where necessary. Skin prick test was done in idiopathic urticaria. Results: The study sample consisted of 62 male and 88 female patients with a mean age of 21-40 years. About 50% of patients showed an ASST positive reaction, 3.9% were positive for antinuclear antibody (ANA, IgE titer was elevated in 37%, H. pylori antibodies was positive in 26.7%. Thyroid antibodies were positive in 6.2%.

    In the majority of neuropsychiatric conditions, marked gender-based differences have been found in the epidemiology, clinical manifestations, and therapy of disease. Emerging data suggest that gender differences exist also in the epidemiology, and pathophysiology of epilepsy. The present review summarizes the current information regarding gender and epilepsy. These differences are regarded from the perspective of innate sex differences in cerebral morphology, structural and functional connections, and assuming that these differences may render men and women differently vulnerable to epileptogenicity.

    CT diagnosis of infantile epilepsy was evaluated. High incidence of abnormal CT findings in infantile spasms and Lennox-Gastaut syndrome was same as in other reports. Comparison between CT findings and neurological complications and that between CT findings and electroencephalogram findings revealed a stronger relationship existing in the former. This suggested that CT is more useful as a measure to detect underlying diseases which are due to organic change of the brain to cause epilepsy, rather than as that to disclose epileptic primary lesions of functional change.

    Restless legs syndrome (RLS) is a common neurological movement disorder occurring in approximately 10% of the general population. The prevalence of moderately severe RLS is 2.7% overall (3.7% for women and 1.7% for men). Epilepsy is also a common neurological disorder with significant associated morbidity and impact on quality of life. We evaluated the severity and frequency of primary RLS in patients with localization-related temporal lobe epilepsy (TLE) and investigated the role of prodromal RLS symptoms as a warning sign and lateralizing indicator. All epilepsy patients seen in the outpatient clinic were screened for movement disorders from 2005 to 2015. Ninety-eight consecutive patients with localization-related TLE (50 right TLE and 48 left TLE) who met inclusion criteria were seen in the outpatient clinic. The control group consisted of 50 individuals with no history or immediate family history of epilepsy. Each patient was evaluated with the International Restless Legs Study Group (IRLSSG) questionnaire, NIH RLS diagnostic criteria, ferritin level, and comprehensive sleep screening including polysomnography. Furthermore, patients with obstructive sleep apnea or a definite cause of secondary restless legs syndrome such as low serum ferritin or serum iron levels were also excluded from the study. There was a significant association between the type of epilepsy and whether or not patients had RLS χ 2 (1)=10.17, p<.01, using the χ 2 Goodness of Fit Test. Based on the odds ratio, the odds of patients having RLS were 4.60 times higher if they had right temporal epilepsy than if they had left temporal epilepsy, serving as a potential lateralizing indicator. A prodromal sensation of worsening RLS occurred in some patients providing the opportunity to intervene at an earlier stage in this subgroup. We identified frequent moderate to severe RLS in patients with epilepsy. The frequency of RLS was much more common than would typically be seen in patients of similar

    The present study aimed to determine the level of felt stigma, overprotection, concealment, and concerns related to epilepsy in different life domains by using culturally-specific scales for Turkish individuals with epilepsy. Also, it aimed to detect relations among the study variables and to determine the variables which predict felt stigma. For this purpose, felt stigma scale, overprotection scale, concealment of epilepsy scale, and concerns of epilepsy scale were administered to two hundred adult persons with epilepsy (PWE). The results showed that almost half of the participants reported felt stigma, overprotection, concealment of epilepsy, concerns related to future occupation, and concerns related to social life. Almost all the study variables show correlations with each other. Concealment of epilepsy, concerns related to social life, and concerns related to future occupation were found as the predictors of felt stigma. Copyright © 2016 Elsevier Inc. All rights reserved.

    Hospital readmissions can be detrimental to patients and may interfere with the potential benefits of the therapeutic procedure. Government agencies have begun to focus on reducing readmissions; however, the etiology of readmissions is lacking. To report the national rates, risk factors, and outcomes associated with 30- and 90-d readmissions following surgery for intractable epilepsy. We queried the Nationwide Readmissions Database from January to September 2013 using International Classification of Diseases, Ninth Edition, Clinical Modification codes to identify all patients with intractable epilepsy, who underwent hemispherectomy (01.52), brain lobectomy (01.53), amydalohippocampectomy, or partial lobectomy (01.59). Predictor variables included epilepsy type, presurgical diagnostic testing, surgery type, medical complications, surgical complications, and discharge disposition. In 1587 patients, the 30- and 90-d readmission rates were 11.5% and 16.8%, respectively. The most common reasons for readmission were persistent epilepsy, video electroencephalography monitoring, postoperative infection, and postoperative central nervous system complication. In multivariable analysis, risk factors associated with both 30- and 90-d readmission were Medicare payer status, lowest quartile of median income, depression, hemispherectomy, and postoperative complications (P < .05). The only unique predictor of 30-d readmission was small bedsize hospital (P = .001). Readmissions within 30 d were associated with longer length of stay (6.8 vs 5.8 d), greater costs ($18 660 vs $15 515), and increased adverse discharges (26.4% vs 21.8%). Following epilepsy surgery, most readmissions that occurred within 30 d can be attributed to management of persistent epilepsy and predicted by Medicare payer status, depression, and complications. These data can assist the clinician in preventing readmissions and assist policy makers determine which admissions are potentially avoidable.

  1. Epilepsy and astrocyte energy metabolism.

    Science.gov (United States)

    Boison, Detlev; Steinhäuser, Christian

    2018-06-01

    Epilepsy is a complex neurological syndrome characterized by neuronal hyperexcitability and sudden, synchronized electrical discharges that can manifest as seizures. It is now increasingly recognized that impaired astrocyte function and energy homeostasis play key roles in the pathogenesis of epilepsy. Excessive neuronal discharges can only happen, if adequate energy sources are made available to neurons. Conversely, energy depletion during seizures is an endogenous mechanism of seizure termination. Astrocytes control neuronal energy homeostasis through neurometabolic coupling. In this review, we will discuss how astrocyte dysfunction in epilepsy leads to distortion of key metabolic and biochemical mechanisms. Dysfunctional glutamate metabolism in astrocytes can directly contribute to neuronal hyperexcitability. Closure of astrocyte intercellular gap junction coupling as observed early during epileptogenesis limits activity-dependent trafficking of energy metabolites, but also impairs clearance of the extracellular space from accumulation of K + and glutamate. Dysfunctional astrocytes also increase the metabolism of adenosine, a metabolic product of ATP degradation that broadly inhibits energy-consuming processes as an evolutionary adaptation to conserve energy. Due to the critical role of astroglial energy homeostasis in the control of neuronal excitability, metabolic therapeutic approaches that prevent the utilization of glucose might represent a potent antiepileptic strategy. In particular, high fat low carbohydrate "ketogenic diets" as well as inhibitors of glycolysis and lactate metabolism are of growing interest for the therapy of epilepsy. © 2017 Wiley Periodicals, Inc.

    Epilepsy is characterized by paroxysmal alterations in behavior and psychological functions, associated with increased neural discharge that is detectable by EEG. In between these paroxysmal events patients may appear superficially normal, but may have neurological signs and neurpsychological deficits. The neurological signs are sometimes correlated with radiologically detectable lesions, but there is little correlation between the CT abnormalities and the EEG focus, and CT abnormalities are rarely found in ''primary'' or ''idiopathic'' forms of epilepsy. Thus, seizure foci documented by ictal EEG can occur in regions that appear normal on CT. Since brain abnormalities implicated in epilepsy are more clearly reflected in measures of neural activity than in measures of anatomy, PET has particular potential for the study of epileptic pathophysiology. It provides the ability to measure local alterations in brain blood flow and metabolism, which are highly coupled with neural activity, and this makes possible the characterization of metabolic changes associated with epilepsy. Thus PET has the potential for contributing to the localization of epileptic activity as well as to the understanding of its pathophysiology

    Epilepsy surgery has become an accepted treatment for drug resistant epilepsy in infants and children. It has gained ground in India over the last decade. Certain epilepsy surgically remediable syndromes have been delineated and should be offered surgery earlier rather than later, especially if cognitive/behavioral development is being compromised. Advances in imaging, particularly in MRI has helped identify surgical candidates. Pre-surgical evaluation includes clinical assessment, structural and functional imaging, inter-ictal EEG, simultaneous video -EEG, with analysis of seizure semiology and ictal EEG and other optional investigations like neuropsychology and other newer imaging techniques. If data are concordant resective surgery is offered, keeping in mind preservation of eloquent cortical areas subserving motor, language and visual functions. In case of discordant data or non-lesional MRI, invasive EEG maybe useful using a two-stage approach. With multi-focal / generalized disease, palliative surgery like corpus callosotomy and vagal nerve stimulation maybe useful. A good outcome is seen in about 2/3rd of patients undergoing resective surgery with a low morbidity and mortality. This review outlines important learning aspects of pediatric epilepsy surgery for the general pediatrician.

    There is a complex, bidirectional interdependence between sex steroid hormones and epilepsy; hormones affect seizures, while seizures affect hormones thereby disturbing reproductive endocrine function. Both female and male sex steroid hormones influence brain excitability. For the female sex steroid hormones, progesterone and its metabolites are anticonvulsant, while estrogens are mainly proconvulsant. The monthly fluctuations in hormone levels of estrogen and progesterone are the basis for catamenial epilepsy described elsewhere in this issue. Androgens are mainly anticonvulsant, but the effects are more varied, probably because of its metabolism to, among others, estradiol. The mechanisms for the effects of sex steroid hormones on brain excitability are related to both classical, intracellularly mediated effects, and non-classical membrane effects due to binding to membrane receptors. The latter are considered the most important in relation to epilepsy. The different sex steroids can also be further metabolized within the brain to different neurosteroids, which are even more potent with regard to their effect on excitability. Estrogens potentiate glutamate responses, primarily by potentiating NMDA receptor activity, but also by affecting GABA-ergic mechanisms and altering brain morphology by increasing dendritic spine density. Progesterone and its main metabolite 5α-pregnan-3α-ol-20-one (3α-5α-THP) act mainly to enhance postsynaptic GABA-ergic activity, while androgens enhance GABA-activated currents. Seizures and epileptic discharges also affect sex steroid hormones. There are close anatomical connections between the temporolimbic system and the hypothalamus controlling the endocrine system. Several studies have shown that epileptic activity, especially mediated through the amygdala, alters reproductive function, including reduced ovarian cyclicity in females and altered sex steroid hormone levels in both genders. Furthermore, there is an asymmetric

    Aside from brain injury and genetic causes, there is emerging information on brain infection and inflammation as a common cause of epilepsy. Neurocysticercosis (NCC), the most common cause of epilepsy worldwide, is caused by brain cysts from the Taenia solium tapeworm. In this article, we provide a critical analysis of current and emerging information on the relationship between NCC infection and epilepsy occurrence. We searched PubMed and other databases for reports on the prevalence of NCC and incidence of epilepsy in certain regions worldwide. NCC is caused by brain cysts from the T. solium and related tapeworms. Many people with NCC infection may develop epilepsy but the rates are highly variable. MRI imaging shows many changes including localization of cysts as well as the host response to treatment. Epilepsy, in a subset of NCC patients, appears to be due to hippocampal sclerosis. Serologic and brain imaging profiles are likely diagnostic biomarkers of NCC infection and are also used to monitor the course of treatments. Limited access to these tools is a key limitation to identify and treat NCC-related epilepsy in places with high prevalence of this parasite infestation. Overall, NCC is a common infection in many patients with epilepsy worldwide. Additional clinical and animal studies could confirm common pathology of NCC as a postinfectious epilepsy that is curable.

  12. Sleep and Epilepsy: Strange Bedfellows No More.

    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.

  13. [Building epilepsy care network in Japan].

    2012-01-01

    Number of epilepsy patient in Japan officially surveyed by our government in 2008 is 219,000, which is only 0.17% of the total population and less than one third of the prevalence rate reported in Western countries. Number of epilepsy surgery per year in Japan is also low and less than half of other countries such as US, UK and Korea. These numbers may suggest that epilepsy care in Japan is not sufficient to cover all hidden medical needs of people with epilepsy at present. To solve this issue, our research group funded by the government have started to build an epilepsy care network among primary care physicians, secondary care neurology specialists and tertiary care epilepsy centers by utilizing a web site: Epilepsy Care Network-Japan (http://www.ecn-japan.com/) from July 2012. We are also proposing an epilepsy care algorithm suitable for our complex medical community consisted with various neurology specialists such as pediatric and adult neurologists, neurosurgeons and psychiatrists. Building Epilepsy Care Network in Japan may facilitate better medical and social support for people with epilepsy in Japan.

    The objective of this observational study was to evaluate the efficacy of medical cannabis for the treatment of refractory epilepsy. Fifty-seven patients (age 1-20 years) with epilepsy of various etiologies were treated with Cannabis oil extract (CBD/THC ratio of 20:1) for at least 3 months (Median follow up time-18 months). Forty-Six Patients were included in the efficacy analysis. Average CBD dose was11.4 mg/kg/d. Twenty-six patients (56%) had ≤50% reduction in mean monthly seizure frequency. There was no statistically significant difference in response rate among various epilepsy etiologies, and cannabis strain used. Younger age at treatment onset (CBD dose (>11 mg/kg/d) were associated with better response to treatment. Adverse reactions were reported in 46% of patients and were the main reason for treatment cessation. Our results suggest that adding CBD-enriched cannabis extract to the treatment regimen of patients with refractory epilepsy may result in a significant reduction in seizure frequency according to parental reports. Randomized controlled trials are necessary to assess its true efficacy. Copyright © 2018 Elsevier B.V. All rights reserved.

    Full Text Available Abstract Background Multiple sclerosis (MS is considered an autoimmune disease of the central nervous system and therapeutic inhibition of leukocyte migration with natalizumab, an anti-alpha4 integrin antibody, is highly effective in patients with MS. Recent studies performed in experimental animal models with relevance to human disease suggested a key role for blood-brain barrier damage and leukocyte trafficking mechanisms also in the pathogenesis of epilepsy. In addition, vascular alterations and increased leukocyte accumulation into the brain were recently documented in patients with refractory epilepsy independently on the disease etiology. Case report Here we describe the clinical course of a 24-year-old patient with MS in whom abrupt tonic-clonic generalized seizures manifested at disease onset. Although MS had a more favorable course, treatment with glatiramer acetate and antiepileptic drugs for 7 years had no control on seizure generation and the patient developed severe refractory epilepsy. Interestingly, generalized seizures preceded new MS relapses suggesting that seizure activity may contribute to MS worsening creating a positive feedback loop between the two disease conditions. Notably, treatment with natalizumab for 12 months improved MS condition and led to a dramatic reduction of seizures. Conclusion Our case report suggests that inhibition of leukocyte adhesion may represent a new potential therapeutic approach in epilepsy and complement the traditional therapy with anti-epileptic drugs.

    Discourse skills - in which the right hemisphere has an important role - enables verbal communication by selecting contextually relevant information and integrating it coherently to infer the correct meaning. However, language research in epilepsy has focused on single word analysis related mainly to left hemisphere processing. The purpose of this study was to investigate discourse abilities in patients with right lateralized medial temporal lobe epilepsy (RTLE) by comparing their performance to that of patients with left temporal lobe epilepsy (LTLE). 74 pharmacoresistant temporal lobe epilepsy (TLE) patients were evaluated: 34 with RTLE and 40 with LTLE. Subjects underwent a battery of tests that measure comprehension and production of conversational and narrative discourse. Disease related variables and general neuropsychological data were evaluated. The RTLE group presented deficits in interictal conversational and narrative discourse, with a disintegrated speech, lack of categorization and misinterpretation of social meaning. LTLE group, on the other hand, showed a tendency to lower performance in logical-temporal sequencing. RTLE patients showed discourse deficits which have been described in right hemisphere damaged patients due to other etiologies. Medial and anterior temporal lobe structures appear to link semantic, world knowledge, and social cognition associated areas to construct a contextually related coherent meaning.

    Objective To examine differences in health care charges following a pediatric epilepsy diagnosis based on changes in health-related quality of life (HRQOL). Methods Billing records were obtained for 171 youth [M (SD) age = 8.9 (4.1) years] newly diagnosed with epilepsy. Differences in health care charges among HRQOL groups (stable low, declining, improving, or stable high as determined by PedsQL™ scores at diagnosis and 12 months after diagnosis) were examined. Results Patients with persistently low or declining HRQOL incurred higher total health care charges in the year following diagnosis (g = .49, g = .81) than patients with stable high HRQOL after controlling for epilepsy etiology, seizure occurrence, and insurance type. These relationships remained consistent after excluding health care charges for behavioral medicine or neuropsychology services (g = .49, g = .80). Conclusions Monitoring HRQOL over time may identify youth with epilepsy at particular risk for higher health care charges. PMID:26503299

    The widespread patient use of artisanal cannabis preparations has preceded quality validation of cannabis use for epilepsy. Neurologists and cannabinoid specialists are increasingly in a position to monitor and guide the use of herbal cannabis in epilepsy patients. We report the retrospective data on efficacy and adverse effects of artisanal cannabis in Patients with medically refractory epilepsy with mixed etiologies in Washington State, California, and Maine. Clinical considerations, including potential risks and benefits, challenges related to artisanal preparations, and cannabinoid dosing, are discussed. Of 272 combined patients from Washington State and California, 37 (14%) found cannabis ineffective at reducing seizures, 29 (15%) experienced a 1-25% reduction in seizures, 60 (18%) experienced a 26-50% reduction in seizures, 45 (17%) experienced a 51-75% reduction in seizures, 75 (28%) experienced a 76-99% reduction in seizures, and 26 (10%) experienced a complete clinical response. Overall, adverse effects were mild and infrequent, and beneficial side effects such as increased alertness were reported. The majority of patients used cannabidiol (CBD)-enriched artisanal formulas, some with the addition of delta-9-tetrahydrocannabinol (THC) and tetrahydrocannabinolic acid (THCA). Four case reports are included that illustrate clinical responses at doses prevention, the use of THC for seizure rescue, and the synergy of cannabinoids and terpenoids in artisanal preparations.

    The aim of the study was to evaluate the influence of precipitating factors and therapy on the outcome of epilepsy with generalized tonic-clonic seizures. Retrospective analysis of data from 34 patients (mean age at seizure onset 19 years; mean duration of follow-up 9.2 years) suffering from epilepsy of either cryptogenic or remote symptomatic (n = 19), or idiopathic (n = 15) etiology. The total number of seizures in all patients was 146. Without treatment 97 seizures manifested during 90.5 years without treatment (1.07 seizures/year), during treatment with carbamazepine or valproate 49 seizures occurred within 224 years (0.2 seizures/year). The frequency of seizures was significantly lower during treatment. Precipitating factors were found in relation to 31% of seizures in patients with remote symptomatic or cryptogenic epilepsy, and for 51% of seizures in patients with idiopathic epilepsy. There was a low frequency of seizures in patients with generalized tonic-clonic seizures. Precipitating factors are common. Antiepileptic drug treatment is effective.

    Reoperations account for >10% in pediatric epilepsy surgery cohorts, and they are especially relevant in young children with catastrophic epilepsy. To determine surgical outcomes and their predictive factors in reoperations for refractory epilepsy in childhood. We retrospectively analyzed presurgical findings, resections, and outcomes of 23 consecutive children who underwent reoperations from 2000 to 2011. Etiology included cortical dysplasia with/without glioneuronal tumor in 19 patients (83%), sole glioneuronal tumor in 2, and tuberous sclerosis and Rasmussen encephalitis in 1 each. The reasons for the failure of the initial surgery were functional considerations in 8 (35%), incorrect delineation of the epileptogenic zone in 8 (35%), and resection not performed as initially planned in 7 (30%) cases. Final procedures included 8 (35%) intralobar, 8 (35%) multilobar resections, and 7 (30%) hemispherotomies. Following reoperations, 14 (61%) patients were seizure free, 6 (26%) showed significant or worthwhile improvement, and 3 (13%) did not respond to surgery. Six of 8 patients who underwent the first resection before the age of 3 years, 6 of 8 whose first resection was limited by functional considerations, and all 7 with hemispherotomy as the final resection achieved seizure freedom after reoperation. Reoperation is particularly beneficial for selected children with refractory epilepsy associated with cortical dysplasia that did not respond to an initial limited and/or early resection but achieved seizure freedom after extensive procedures. When indicated, reoperation should be performed at the youngest possible age to profit from higher functional plasticity in compensating for neurological deficit.

    and had follow-up beyond the time of epilepsy diagnosis. Children were followed for a median of 7.87 years after the time of diagnosis (range 0.04–29.49 years) for a total of 4558.5 person-years. Sixteen (3.4%) of the children died, or 3.51 deaths per 1000 person-years. Two deaths were epilepsy-related (12.5%) for a rate of 0.44 per 1000 person years. One of these children died of probable SUDEP and one died of aspiration during a seizure. The remaining 14 deaths (87.5%) were due to other complications of underlying disease. Several risk factors for mortality were found, including abnormal cognition, abnormal neurologic exam, structural/metabolic etiology for epilepsy, and poorly controlled epilepsy. PMID:22989286

    Epilepsy is a heterogeneous group of disorders, often associated with significant comorbidity, such as intellectual disability and skin disorder. The genetic underpinnings of many epilepsies are still being elucidated, and we expect further advances over the coming 5 years, as genetic technology improves and prices fall for whole exome and whole genome sequencing. At present, there are several well-characterized complex epilepsies associated with single gene disorders; we review some of these here. They include well-recognized syndromes such as tuberous sclerosis complex, epilepsy associated with Rett syndrome, some of the progressive myoclonic epilepsies, and novel disorders such as epilepsy associated with mutations in the PCDH 19 gene. These disorders are important in informing genetic testing to confirm a diagnosis and to permit better understanding of the variability in phenotype-genotype correlation.

    In the 19th century, Hughlings Jackson relied on clinical history, seizure semiology, and the neurologic examination as methods for seizure localization to inform the first epilepsy surgeries. In the 20th century, psychological and neuropsychological tests were first employed as both diagnostic and prognostic measures. The contemporary practice of epilepsy evaluation and management includes neuropsychology as a critical component of epilepsy care and research, and epilepsy and neuropsychology have enjoyed a very special and synergistic relationship. This paper reviews how epilepsy has shaped the practice of neuropsychology as a clinical service by asking critical questions that only neuropsychologists were in a position to answer, and how clinical care of epilepsy patients has been significantly improved based on neuropsychology's unique contributions.

    Epilepsy is, of course, not one disease but rather a huge number of disorders that can present with seizures. In common, they all reflect brain dysfunction. Moreover, they can affect the mind and, of course, behavior. While animals too may suffer from epilepsy, as far as we know, the electrical discharges are less likely to affect the mind and behavior, which is not surprising. While the epileptic seizures themselves are episodic, the mental and behavioral changes continue, in many cases, interictally. The episodic mental and behavioral manifestations are more dramatic, while the interictal ones are easier to study with anatomical and functional studies. The following extended summaries complement those presented in Part 1. PMID:23764496

    Full Text Available Background: Vocal fold polyp is one of the most common causes for hoarseness. Many different etiological factors contribute to vocal fold polyp formation. The aim of the study was to find out whether the etiological factors for polyp formation have changed in the last 30 years.Methods: Eighty-one patients with unilateral vocal fold polyp were included in the study. A control group was composed of 50 volunteers without voice problems who matched the patients by age and gender. The data about etiological factors and the findings of phoniatric examination were obtained from the patients' medical documentation and from the questionnaires for the control group. The incidence of etiological factors was compared between the two groups. The program SPSS, Version 18 was used for statistical analysis.Results: The most frequent etiological factors were occupational voice load, GER, allergy and smoking. In 79% of patients 2 – 6 contemporary acting risk factors were found. Occupational voice load (p=0,018 and GER (p=0,004 were significantly more frequent in the patients than in the controls. The other factors did not significantly influence the polyp formation.Conclusions: There are several factors involved simultaneously in the formation of vocal fold polyps both nowadays and 30 years ago. Some of the most common factors remain the same (voice load, smoking, others are new (GER, allergy, which is probably due to the different lifestyle and working conditions than 30 years ago. Occupational voice load and GER were significantly more frequently present in the patients with polyp than in the control group. Regarding the given results it is important to instruct workers with professional vocal load about etiological factors for vocal fold polyp formation.

    2016-01-01

    Full Text Available Among drug-resistant epilepsies, epileptic syndromes, characterized by combination of several types of seizures, are considered to be the most difficult in terms of treatment. Lennox–Gastaut syndrome is one of them. It manifests with polymorphic seizures (tonic axial, myatonic, atypical absence seizures, status epilepticus of minor motor seizures, myoclonic, generalized convulsive, and focal seizures. This is a heterogeneous disease, represented by a complex of clinical and electroencephalographic manifestations with various etiology. Current review is devoted to a novel antiepileptic drug rufinamide, which has a new mechanism of action. The drug has been registered in Russia in 2015. The authors also describe their own experience of rufinamide usage in the treatment of drug-resistant focal epilepsy as a part of multicomponent therapy for polymorphic seizures. One patient achieved clinical remission for 16 months; the second one had more than 50 % decrease in seizures frequency with a remission of drop-attacks.

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.

    Positron emission tomography (PET) and single photon emission computed tomography (SPECT) imaging are very useful for the management of patients with medically refractory partial epilepsy. Presurgical evaluation of patients with medically refractory partial epilepsy often included PET imaging using FDG. The use of SPECT in these patients adds some more information and gives the clinicians the possibility of having ictal imaging. Furthermore, PET and SPECT imaging are performed to better understand the pathophysiology of epilepsy. (authors)

    Temporal lobe epilepsy is diagnosed by clinical symptoms and signs and by localization of an epileptogenic focus. A brain SPECT study of two patients with temporal lobe epilepsy, using 99m Tc-HMPAO, was used to demonstrate a perfusion abnormality in the temporal lobe, while brain CT and MRI were non-contributory. The electroencephalogram, though abnormal, did not localize the diseased area. The potential role of the SPECT study in diagnosis and localization of temporal lobe epilepsy is discussed. (orig.)

    1994-01-01

    We retrospectively examined the MR imaging (MRI) findings in 144 patients with epilepsy (31 with temporal lobe epilepsy and 113 with other epilepsies). 110 cases (76.4%) showed abnormal findings such as spotty lesions in white matter, hippocampal atrophy and/or signal change, ventricular dilatation and/or deformity, developmental lesions, brain tumors and so on. Hippocampal atrophy and/or signal change was shown in 74.1% of temporal lobe epilepsy, a remarkably high percentage (p<0.01) compared with the other types of epilepsies (18.1%). This finding means that hippocampal lesions may play a large part in the cause of temporal lobe epilepsy. Investigation of the relationship between clinical term and abnormal findings revealed that the longer the clinical term, the large the number of hippocampal lesions, regardless of whether it is temporal lobe epilepsy or not. Thus hippocampal lesions may occur as a result of hypoxia accompanied with seizure. Therefore we recommend horizontal and/or vertical sections of hippocampus in MR imaging of all patients with epilepsy. Even though MR finding may reflect some secondary lesions, MRI will shed some light on the proper understanding of epilepsy. (author)

    Because of its sensitivity and high tissue contrast, magnetic resonance imaging (MRI) is the technique of choice for structural imaging in epilepsy. In this review the effect of using optimised scanning protocols and the use of high field MR systems on detection sensitivity is discussed. Also, the clinical relevance of adequate imaging in patients with focal epilepsy is highlighted. The most frequently encountered MRI findings in epilepsy are reported and their imaging characteristics depicted. Imaging focus will be on the diagnosis of hippocampal sclerosis and malformations of cortical development, two major causes of medically intractable focal epilepsy. (orig.)

    Epilepsy is a type of chronic brain disease that results from an abnormally high synchronization of neuronal discharge. The typical clinical features of epilepsy are paroxysms and transient and stereotyped brain dysfunction. Many cases of epileptic seizures occurring during anesthesia have been reportedx. Recently, risk assessment of epileptic seizures during surgery and anesthesia has gained increasing attention. In this review, we systematically summarize the influence of anesthesia on epileptic seizures; the types, durations and frequencies of seizures related to anesthesia; and the epidemiology, prevention, treatment and prognosis of epilepsy. We also explore the possible mechanism of epilepsy and provide guidance for anesthesia during surgeries.

    Epileptic encephalopathy with continuous diffuse spike-waves during slow-wave sleep (ECSWS) presents clinically with infrequent nocturnal focal seizures, atypical absences related to secondary bilateral synchrony, negative myoclonia, and atonic and rare generalized tonic-clonic seizures. The unique electroencephalography (EEG) pattern found in ECSWS consists of continuous, diffuse, bilateral spike-waves during slow-wave sleep. Despite the eventual disappearance of clinical seizures and EEG abnormalities by adolescence, the prognosis is guarded in most cases because of neuropsychological and behavioral deficits. ECSWS has a heterogeneous etiology (genetic, structural, and unknown). Because epilepsy and electroencephalography (EEG) abnormalities in epileptic encephalopathy with continuous diffuse spike-waves during slow-wave sleep (ECSWS) are self-limited and age related, the need for ongoing medical care and transition to adult care might be questioned. For adolescents in whom etiology remains unknown (possibly genetic) and who experience the disappearance of seizures and EEG abnormalities, there is rarely need for long-term neurologic follow-up, because often a relatively normal cognitive and social evolution follows. However, the majority of patients with structural and possibly "genetic syndromic" etiologies will have persistent cognitive deficits and will need suitable socioeducative care. Therefore, the transition process in ECSWS will depend mainly on etiology and its related features (epileptic active phase duration, and cognitive and behavioral evolution) and revolve around neuropsychological and social support rather than medical and pharmacologic follow-up.

    2017-09-05

    Pannexin-1 (Panx1) expression is raised in several animal seizure models and in resected human epileptic brain tissue, suggesting relevance to epilepsy. Multiple factors that are characteristic of seizures are thought to regulate Panx1 channel opening, including elevated levels of extracellular K + . Panx1, when open, 1) releases ATP, glutamate, and other metabolites into the extracellular medium, and 2) may depolarize the membrane due to a channel reversal potential around 0mV. Resultant ATP release from stimulated Panx1 can activate purinergic receptors, including P2X7 receptors. Glutamate and other signaling molecules released by Panx1 opening may have both excitatory and inhibitory actions on seizure generation. This review examines the critical and complex roles of Panx1 channels in epilepsy, which could provide a basis for future therapeutics. Copyright © 2017 Elsevier B.V. All rights reserved.

  5. Temporal Lobe Epilepsy in Children

    2012-01-01

    The temporal lobe is a common focus for epilepsy. Temporal lobe epilepsy in infants and children differs from the relatively homogeneous syndrome seen in adults in several important clinical and pathological ways. Seizure semiology varies by age, and the ictal EEG pattern may be less clear cut than what is seen in adults. Additionally, the occurrence of intractable seizures in the developing brain may impact neurocognitive function remote from the temporal area. While many children will respond favorably to medical therapy, those with focal imaging abnormalities including cortical dysplasia, hippocampal sclerosis, or low-grade tumors are likely to be intractable. Expedient workup and surgical intervention in these medically intractable cases are needed to maximize long-term developmental outcome. PMID:22957247

    Full Text Available ABSTRACT The ketogenic diet (KD, a high-fat, low-carbohydrate, and adequate-protein diet is an established, effective nonpharmacologic treatment option for intractable childhood epilepsy. The KD was developed in 1921 and even though it has been increasingly used worldwide in the past decade, many neurologists are not familiar with this therapeutic approach. In the past few years, alternative and more flexible KD variants have been developed to make the treatment easier and more palatable while reducing side effects and making it available to larger group of refractory epilepsy patients. This review summarizes the history of the KD and the principles and efficacy of the classic ketogenic diet, medium-chain triglyceride(s (MCT ketogenic diet, modified Atkins diet, and low glycemic index treatment.

    Mozart's Sonata for Two Pianos in D major, K.448 (Mozart K.448), has been shown to improve mental function, leading to what is known as the Mozart Effect. Our previous work revealed that epileptiform discharges in children with epilepsy decrease during and right after listening to Mozart K.448. However, the duration of the effect was not studied. In the study described here, we evaluated the long-term effect of Mozart K.448 on epileptiform discharges in children with epilepsy. Eighteen children with epilepsy whose seizures were clinically well controlled with antiepileptic drugs were included. For each child, EEGs had revealed persistent epileptiform discharges for at least 6 months. These patients listened to Mozart K.448 for 8 minutes once a day before bedtime for 6 months. Epileptiform discharges were recorded and compared before and after 1, 2, and 6 months of listening to Mozart K.448. All of the children remained on the same antiepileptic drug over the 6 months. Relationships between number of epileptiform discharges and foci of discharges, intelligence, epilepsy etiology, age, and gender were analyzed. Epileptiform discharges significantly decreased by 53.2±47.4, 64.4±47.1, and 71.6±45.8%, respectively, after listening to Mozart K.448 for 1, 2, and 6 months. All patients except those with occipital discharges showed a significant decrease in epileptiform discharges. Patients with normal intelligence and idiopathic epilepsy had greater decreases than those with mental retardation and symptomatic epilepsy. Age and gender did not affect the results. We conclude that long-term listening to Mozart K.448 may be effective in decreasing epileptiform discharges in children with epilepsy in a chronologically progressive manner.

  9. Etiology of Inguinal Hernias: A Comprehensive Review

    2017-09-01

    Full Text Available BackgroundThe etiology of inguinal hernias remains uncertain even though the lifetime risk of developing an inguinal hernia is 27% for men and 3% for women. The aim was to summarize the evidence on hernia etiology, with focus on differences between lateral and medial hernias.ResultsLateral and medial hernias seem to have common as well as different etiologies. A patent processus vaginalis and increased cumulative mechanical exposure are risk factors for lateral hernias. Patients with medial hernias seem to have a more profoundly altered connective tissue architecture and homeostasis compared with patients with lateral hernias. However, connective tissue alteration may play a role in development of both subtypes. Inguinal hernias have a hereditary component with a complex inheritance pattern, and inguinal hernia susceptible genes have been identified that also are involved in connective tissue homeostasis.ConclusionThe etiology of lateral and medial hernias are at least partly different, but the final explanations are still lacking on certain areas. Further investigations of inguinal hernia genes may explain the altered connective tissue observed in patients with inguinal hernias. The precise mechanisms why processus vaginalis fails to obliterate in certain patients should also be clarified. Not all patients with a patent processus vaginalis develop a lateral hernia, but increased intraabdominal pressure appears to be a contributing factor.

    This study aims to define symptoms and etiology and determine how to prevent chronic rhinosinusitis in children. Between February 2003 and February 2005, 50 pediatric patients (25 girls and 25 boys; mean age 8.22 years; range 4 to 14 years) with chronic rhinosinusitis were included in the study. The patients were questioned about anterior/posterior nasal dripping, night cough, headache, nausea, vomiting and nasal obstruction for symptomatology; about school condition, smoking behavior of parents and history of asthma for etiology. Hemogram, serum biochemistry, allergy test, nasal smear, chest and lateral neck radiography and sweat test were performed. Symptomatologic examination revealed that 48% had anterior nasal dripping, 62% with postnasal dripping, 70% with headache and 90% with nasal obstruction. Evaluation of etiological factors revealed that 68% were going to school, 48% of the parents had the history of smoking, 42% with allergy test-positivity and 60% with adenoid vegetation. Our study results indicated that environmental factors are important as etiological factors in rhinosinusitis. For prevention, we recommend restriction of close relationship at school, not to smoke at home and vaccination in each year with influenza and S. pneumonia vaccine.

    Epidemics of CKD of uncertain etiology (CKDu) are emerging around the world. Highlighting common risk factors for CKD of uncertain etiology across various regions and populations may be important for health policy and public health responses. We searched PubMed, Embase, Scopus and Web of Science databases to identify published studies on CKDu. The search was generated in January of 2015; no language or date limits were used. We used a vote-counting method to evaluate exposures across all studies. We identified 1607 articles, of which 26 met inclusion criteria. Eighteen (69%) were conducted in known CKDu-endemic countries: Sri Lanka (38%), Nicaragua (19%), and El Salvador (12%). The other studies were from India, Japan, Australia, Mexico, Sweden, Tunisia, Tanzania, and the United States. Heavy metals, heat stress, and dietary exposures were reported across all geographic regions. In south Asia, family history, agrochemical use, and heavy metal exposures were reported most frequently, whereas altitude and temperature were reported only in studies from Central America. Across all regions, CKDu was most frequently associated with a family history of CKDu, agricultural occupation, men, middle age, snake bite, and heavy metal exposure. Studies examining etiologies of CKDu have reported many exposures that are heterogeneous and vary by region. To identify etiologies of CKDu, designing consistent and comparative multisite studies across high-risk populations may help elucidate the importance of region-specific versus global risk factors.

    Sexual behavior changes as well as depression, anxiety, and organic mood/personality disorders have been reported in temporal lobe epilepsy (TLE) patients before and after epilepsy surgery. The authors describe a 14-year-old girl with symptoms of excessive masturbation in inappropriate places, social withdrawal, irritability, aggressive behavior, and crying spells after selective amygdalohippocampectomy for medically intractable TLE with hippocampal sclerosis. Since the family members felt extremely embarrassed, they were upset and angry with the patient which, in turn, increased her depressive symptoms. Both her excessive masturbation behavior and depressive symptoms remitted within 2 months of psychoeducative intervention and treatment with citalopram 20mg/day. Excessive masturbation is proposed to be related to the psychosocial changes due to seizure-free status after surgery as well as other possible mechanisms such as Kluver-Bucy syndrome features and neurophysiologic changes associated with the cessation of epileptic discharges. This case demonstrates that psychiatric problems and sexual changes encountered after epilepsy surgery are possibly multifactorial and in adolescence hypersexuality may be manifested as excessive masturbation behavior.

  18. Epilepsy and recommendations for breastfeeding.

    2015-05-01

    The objective of this paper is to provide a synopsis of benefits and potential harmful effects of exposure to antiepileptic drugs (AEDs) via breastmilk, and present recommendations for breastfeeding in women with epilepsy. The article is based on a discretionary selection of English language articles retrieved by a literature search in the PubMed database, the LactMed database, and the authors' clinical experience. Breastfeeding is associated with benefits for the infant, including nutrition, protection against infectious and immunological disease, and promotion of development and psychological attachment. Exposure to AEDs via breastmilk could potentially produce side effects or negatively affect development. Most studies on AED transfer through breastmilk report infant serum levels well below the limit of an expected pharmacological effect. Some drugs have the potential to reach significant serum levels in breastfed infants, such as barbiturates, benzodiazepines, lamotrigine, and ethosuximide. Thus, breastfed infants should be monitored for side effects. Still, adverse symptoms are rarely reported in breastfed infants of mothers taking AEDs, and prospective studies have failed to demonstrate any negative developmental effects in children that have been exposed to AEDs via breastmilk. The nursing infant's degree of drug exposure can be minimized by breastfeeding when drug concentrations in the milk are low, reducing maternal AED dosage to prepregnancy levels, and administering mixed nutrition. Most AEDs are considered safe or moderately safe during breastfeeding. Mothers with epilepsy should be encouraged to breastfeed, provided careful monitoring of the infant.

  19. Epilepsy and music: practical notes.

    Science.gov (United States)

    Maguire, M

    2017-04-01

    Music processing occurs via a complex network of activity far beyond the auditory cortices. This network may become sensitised to music or may be recruited as part of a temporal lobe seizure, manifesting as either musicogenic epilepsy or ictal musical phenomena. The idea that sound waves may directly affect brain waves has led researchers to explore music as therapy for epilepsy. There is limited and low quality evidence of an antiepileptic effect with the Mozart Sonata K.448. We do not have a pathophysiological explanation for the apparent dichotomous effect of music on seizures. However, clinicians should consider musicality when treating patients with antiepileptic medication or preparing patients for epilepsy surgery. Carbamazepine and oxcarbazepine each may cause a reversible altered appreciation of pitch. Surgical cohort studies suggest that musical memory and perception may be affected, particularly following right temporal lobe surgery, and discussion of this risk should form part of presurgical counselling.

    To investigate the effects of temporal lobe epilepsy and idiopathic epilepsy on cognitive function and emotion in children and the risk factors for cognitive impairment. A retrospective analysis was performed for the clinical data of 38 children with temporal lobe epilepsy and 40 children with idiopathic epilepsy. The controls were 42 healthy children. All subjects received the following neuropsychological tests: Montreal Cognitive Assessment (MoCA) scale, verbal fluency test, digit span test, block design test, Social Anxiety Scale for Children (SASC), and Depression Self-rating Scale for Children (DSRSC). Compared with the control group, the temporal lobe epilepsy and idiopathic epilepsy groups showed significantly lower scores of MoCA, verbal fluency, digit span, and block design (Pepilepsy group, the temporal lobe epilepsy group showed significantly lower scores of MoCA, verbal fluency, digit span, and block design (Ptemporal lobe epilepsy group, MoCA score was negatively correlated with SASC score, DSRSC score, and seizure frequency (r=-0.571, -0.529, and -0.545 respectively; Pepilepsy group, MoCA score was also negatively correlated with SASC score, DSRSC score, and seizure frequency (r=-0.542, -0.487, and -0.555 respectively; Ptemporal lobe epilepsy and idiopathic epilepsy show impaired whole cognition, verbal fluency, memory, and executive function and have anxiety and depression, which are more significant in children with temporal lobe epilepsy. High levels of anxiety, depression, and seizure frequency are risk factors for impaired cognitive function.

  1. Understanding Death in Children With Epilepsy.

    Death in children with epilepsy is profoundly disturbing, with lasting effects on the family, community, and health care providers. The overall risk of death for children with epilepsy is about ten times that of the general population. However, the risk of premature death for children without associated neurological comorbidities is similar to that of the general population, and most deaths are related to the cause of the epilepsy or associated neurological disability, not seizures. The most common cause of seizure-related death in children with epilepsy is sudden unexpected death in epilepsy (SUDEP). SUDEP is relatively uncommon in childhood, but the risk increases if epilepsy persists into adulthood. Although the direct cause of SUDEP remains unknown, most often death follows a generalized convulsive seizure and the risk of SUDEP is strongly related to drug-resistant epilepsy and frequent generalized tonic-clonic seizures. The most effective SUDEP prevention strategy is to reduce the frequency of seizures, although a number of seizure detection devices are under development and in the future may prove to be useful for seizure detection for those at particularly high risk. There are distinct benefits for health care professionals to discuss mortality with the family soon after the diagnosis of epilepsy. An individual approach is appropriate. When a child with epilepsy dies, particularly if the death was unexpected, family grief may be profound. Physicians and other health care professionals have a critical role in supporting families that lose a child to epilepsy. This review will provide health care providers with information needed to discuss the risk of death in children with epilepsy and support families following a loss. Copyright © 2017 Elsevier Inc.

  2. Dictator Perpetuus: Julius Caesar--did he have seizures? If so, what was the etiology?

    Science.gov (United States)

    Hughes, John R

    2004-10-01

    The "Dictator Perpetuus" of the Roman Empire, the great Julius Caesar, was not the one for whom the well-known cesarean operation was named; instead, this term is derived from a Latin word meaning "to cut." Caesar likely had epilepsy on the basis of four attacks that were probably complex partial seizures: (1) while listening to an oration by Cicero, (2) in the Senate while being offered the Emperor's Crown, and in military campaigns, (3) near Thapsus (North Africa) and (4) Corduba (Spain). Also, it is possible that he had absence attacks as a child and as a teenager. His son, Caesarion, by Queen Cleopatra, likely had seizures as a child, but the evidence is only suggestive. His great-great-great grandnephews Caligula and Britannicus also had seizures. The etiology of these seizures in this Julio-Claudian family was most likely through inheritance, with the possibility of sudden unexpected death in epilepsy (SUDEP) in his great grandfather and also his father. Our best evidence comes from the ancient sources of Suetonius, Plutarch, Pliny, and Appianus.

  3. Febrile Infection-Related Epilepsy Syndrome (FIRES): An Overview of Treatment and Recent Patents.

    2018-05-08

    New-onset refractory status epilepticus (NORSE) refers to a clinical presentation in a patient without active epilepsy or other existing relevant neurological disorder, with new onset of refractory status epilepticus in the absence of a clear acute or active structural, metabolic, or toxic cause. Febrile infection-related epilepsy syndrome (FIRES) is a subset of NORSE that requires a febrile infection between 24 hours and 2 weeks prior to the onset of refractory status epilepticus, with or without fever at the onset of status epilepticus, and with no restriction to the age of the patient. The literature on FIRES is scarce. This article reviews the pathophysiology, clinical features, and various treatment modalities in the treatment of FIRES. A Medline/Pubmed search was conducted using Clinical Queries with the key terms "febrile infection-related epilepsy syndrome", "FIRES", "new-onset refractory status epilepticus" and "NORSE". The search strategy included meta-analyses, randomized controlled trials, clinical trials, reviews and pertinent references. Patents were searched using the key term "FIRES", "NORSE" and "febrile epilepsy syndrome" from www.google.com/patents, www.uspto.gov, and www.freepatentsonline.com. FIRES almost invariably begins with a mild nonspecific febrile illness in an otherwise healthy individual. Twenty four hours to two weeks later, seizures begin and quickly become very frequent and worsen, becoming status epilepticus. Seizures can be simple motor, complex partial or secondary generalized. The exact etiology is no known. It is possible that the syndrome is caused by an inflammatory or autoimmune mechanism. Seizures in FIRES are notoriously very difficult to treat. Treatment modalities include, among others, various antiepileptic drugs, ketogenic diet, intravenous corticosteroids, intravenous immunoglobulin, and burst-suppression coma. Outcome is poor; most children are left with significant cognitive disability and refractory epilepsy

    We aimed to investigate the long-term seizure outcome of children and adolescents who were undergoing epilepsy surgery in the parietooccipital cortex and determine their predictive factors. We retrospectively analyzed the data of 50 consecutive patients aged 11.1 (mean) ± 5.1 (standard deviation) years at surgery. All patients but one had a magnetic resonance imaging (MRI)-visible lesion. Resections were parietal in 40%, occipital in 32%, and parietooccipital in 28% cases; 24% patients additionally underwent a resection of the posterior border of the temporal lobe. Etiology included focal cortical dysplasia in 44%, benign tumors (dysembryoplastic neuroepithelial tumor, ganglioglioma, angiocentric glioma, and pilocystic astrocytoma) in 32%, peri- or postnatal ischemic lesions in 16%, and tuberous sclerosis in 8% cases. At last follow-up (mean 8 years, range 1.5-18 years), 60% patients remained seizure-free (Engel class I): 30% had discontinued and 20% had reduced antiepileptic drugs. Most seizure recurrences (71%) occurred within the first 6 months, and only three patients presented with seizures ≥2 years after surgery. Independent predictors of seizure recurrence included left-sided as well as parietal epileptogenic zones and resections. Longer epilepsy duration to surgery was identified as the only modifiable independent predictor of seizure recurrence. Our study demonstrates that posterior cortex epilepsy surgery is highly effective in terms of lasting seizure control and antiepileptic drug cessation in selected pediatric candidates. Most importantly, our data supports the early consideration of surgical intervention in children and adolescents with refractory posterior cortex epilepsy.

    There is accumulating evidence to suggest psychiatric disorders, such as bipolar disorder and schizophrenia, share common etiologies, pathophysiologies, genetics, and drug responses with many of the epilepsies. Here, we explored overlaps in cellular/molecular, electrophysiological, and behavioral phenotypes between putative mouse models of bipolar disorder/schizophrenia and epilepsy. We tested the hypothesis that an immature dentate gyrus (iDG), whose association with psychosis in patients has recently been reported, represents a common phenotype of both diseases. Behaviors of calcium/calmodulin-dependent protein kinase II alpha (α-CaMKII) heterozygous knock-out (KO) mice, which are a representative bipolar disorder/schizophrenia model displaying iDG, and pilocarpine-treated mice, which are a representative epilepsy model, were tested followed by quantitative polymerase chain reaction (qPCR)/immunohistochemistry for mRNA/protein expression associated with an iDG phenotype. In vitro electrophysiology of dentate gyrus granule cells (DG GCs) was examined in pilocarpine-treated epileptic mice. The two disease models demonstrated similar behavioral deficits, such as hyperactivity, poor working memory performance, and social withdrawal. Significant reductions in mRNA expression and immunoreactivity of the mature neuronal marker calbindin and concomitant increases in mRNA expression and immunoreactivity of the immature neuronal marker calretinin represent iDG signatures that are present in both mice models. Electrophysiologically, we have confirmed that DG GCs from pilocarpine-treated mice represent an immature state. A significant decrease in hippocampal α-CaMKII protein levels was also found in both models. Our data have shown iDG signatures from mouse models of both bipolar disorder/schizophrenia and epilepsy. The evidence suggests that the iDG may, in part, be responsible for the abnormal behavioral phenotype, and that the underlying pathophysiologies in epilepsy

  6. Mechanisms of prickle1a function in zebrafish epilepsy and retinal neurogenesis

    Directory of Open Access Journals (Sweden)

    Xue Mei

    2013-05-01

    Epilepsy is a complex neurological disorder characterized by unprovoked seizures. The etiology is heterogeneous with both genetic and environmental causes. Genes that regulate neurotransmitters and ion channels in the central nervous system have been associated with epilepsy. However, a recent screening in human epilepsy patients identified mutations in the PRICKLE1 (PK1 locus, highlighting a potentially novel mechanism underlying seizures. PK1 is a core component of the planar cell polarity network that regulates tissue polarity. Zebrafish studies have shown that Pk1 coordinates cell movement, neuronal migration and axonal outgrowth during embryonic development. Yet how dysfunction of Pk1 relates to epilepsy is unknown. To address the mechanism underlying epileptogenesis, we used zebrafish to characterize Pk1a function and epilepsy-related mutant forms. We show that knockdown of pk1a activity sensitizes zebrafish larva to a convulsant drug. To model defects in the central nervous system, we used the retina and found that pk1a knockdown induces neurite outgrowth defects; yet visual function is maintained. Furthermore, we characterized the functional and biochemical properties of the PK1 mutant forms identified in human patients. Functional analyses demonstrate that the wild-type Pk1a partially suppresses the gene knockdown retinal defects but not the mutant forms. Biochemical analysis reveals increased ubiquitylation of one mutant form and decreased translational efficiency of another mutant form compared with the wild-type Pk1a. Taken together, our results indicate that mutation of human PK1 could lead to defects in neurodevelopment and signal processing, providing insight into seizure predisposition in these patients.

  7. Preventing cognitive impairment in children with epilepsy

    Full Text Available It is well known that there is high quality evidence of epilepsy surgery as an effective and safe option for patients with drug refractory epilepsy by advanced imaging technology and computerized electrophysiological facilities during recent three decades. However, it still remains debate regarding necessities of epilepsy surgery in terms of less satisfactory surgical outcome, especially in non-lesional neocortical epilepsies. This review is for the role of epileptic neurosurgeon rather than the role of epilepsy surgery, namely, the necessity of neurosurgeon's positive participation starting from the first visit of epilepsy patients followed by pertaining process by stages and its degree of contribution. All experienced epilepsy centers also need innovative or challenging trial absolutely through this kind of standpoint, because all of the present protocols and techniques are coming from the past. In any event, the interdepartmental and interpersonal cooperation is inevitable especially for improving patient's quality of life. Serious neurosurgical considerations are needed for patients with intractable epilepsies, especially in referred cases from other center for the purpose of double check, and incongruent cases with contrary opinions by epileptologist.

  11. The representation of epilepsy in popular music.

    Baxendale, Sallie

    2008-01-01

    Much can be learned about the contemporary stereotypes associated with epilepsy by studying the representation of the disorder in paintings, literature, and movies. Popular music is arguably the most accessible and ubiquitous of the creative art forms, touching most of us on a daily basis. Reviewed here are the ways in which epilepsy and seizures are used in the lyrics of musicians from a wide variety of musical genres, from hip-hop to rhythm and blues. Many of the ancient associations of epilepsy with madness, horror, and lunacy can be found in these lyrics. However, the language of epilepsy has also been appropriated by some musical artists to represent a state of sexual ecstasy and dance euphoria. The references to these states as "epilepsy" or a "seizure" in numerous songs suggest that this shorthand is widely recognized within some subcultures. Although epilepsy has frequently been associated with female sexual availability in other creative art forms, this novel use of the language of epilepsy represents a contemporary departure in the artistic application of epilepsy-related images and associations in the 21st century.

  1. Epilepsy classification and additional definitions in occipital lobe epilepsy.

    Science.gov (United States)

    Yilmaz, Kutluhan; Karatoprak, Elif Yüksel

    2015-09-01

    To evaluate epileptic children with occipital lobe epilepsy (OLE) in the light of the characteristics of Panayiotopoulos syndrome and late-onset occipital lobe epilepsy of Gastaut (OLE-G). Patients were categorized into six groups: primary OLE with autonomic symptoms (Panayiotopoulos syndrome), primary OLE with visual symptoms (OLE-G), secondary OLE with autonomic symptoms (P-type sOLE), secondary OLE with visual symptoms (G-type sOLE), and non-categorized primary OLE and non-categorized secondary OLE according to characteristic ictal symptoms of both Panayiotopoulos syndrome and OLE-G, as well as aetiology (primary or secondary). Patients were compared with regards to seizure symptoms, aetiology, cranial imaging, EEG, treatment and outcome. Of 108 patients with OLE (6.4±3.9 years of age), 60 patients constituted primary groups (32 with Panayiotopoulos syndrome, 11 with OLE-G, and 17 with non-categorized primary OLE); the other 48 patients constituted secondary groups (eight with P-type sOLE, three with G-type sOLE, and 37 with non-categorized sOLE). Epileptiform activity was restricted to the occipital area in half of the patients. Generalized epileptiform activity was observed in three patients, including a patient with Panayiotopoulos syndrome (PS). Only one patient had refractory epilepsy in the primary groups while such patients made up 29% in the secondary groups. In OLE, typical autonomic or visual ictal symptoms of Panayiotopoulos syndrome and OLE-G do not necessarily indicate primary (i.e. genetic or idiopathic) aetiology. Moreover, primary OLE may not present with these symptoms. Since there are many patients with OLE who do not exhibit the characteristics of Panayiotopoulos syndrome or OLE-G, additional definitions and terminology appear to be necessary to differentiate between such patients in both clinical practice and studies.

  2. Dendritic ion channelopathy in acquired epilepsy

    Science.gov (United States)

    Poolos, Nicholas P.; Johnston, Daniel

    2012-01-01

    Summary Ion channel dysfunction or “channelopathy” is a proven cause of epilepsy in the relatively uncommon genetic epilepsies with Mendelian inheritance. But numerous examples of acquired channelopathy in experimental animal models of epilepsy following brain injury have also been demonstrated. Our understanding of channelopathy has grown due to advances in electrophysiology techniques that have allowed the study of ion channels in the dendrites of pyramidal neurons in cortex and hippocampus. The apical dendrites of pyramidal neurons comprise the vast majority of neuronal surface membrane area, and thus the majority of the neuronal ion channel population. Investigation of dendritic ion channels has demonstrated remarkable plasticity in ion channel localization and biophysical properties in epilepsy, many of which produce hyperexcitability and may contribute to the development and maintenance of the epileptic state. Here we review recent advances in dendritic physiology and cell biology, and their relevance to epilepsy. PMID:23216577

  3. Maternal Mortality in Women with Epilepsy

    LENUS (Irish Health Repository)

    Holohan, M

    2016-10-01

    It is estimated that, in Ireland, there are 10,000 women with epilepsy of childbearing potential1. In this paper the maternal mortality rate for women with epilepsy attending the Rotunda Hospital Epilepsy Clinic 2004 - 2013 was determined. There were 3 maternal deaths in women with epilepsy during this time, which represents a mortality rate of 0.8%. In those women who died, there were concerns in relation to risks to the foetus by taking Anti-Epileptic Drugs (AED) and also issues with access to neurology services before pregnancy, acceptance of specialist support and lack of consistency in advice from health care professionals outside of Ireland. Implementing the nationally agreed care plan for women with epilepsy will improve the quality of care given and potentially we will see a reduction in maternal mortality in these women.

    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

    2008-01-01

    To determine the causes of short stature in children with special emphasis on growth hormone deficiency. Two hundred and fourteen children (140 boys and 74 girls), ranging from 02 to 15 years presenting with short stature were studied. Height and weight were plotted on appropriate growth charts and centiles determined. Relevant hematological and biochemical investigations including thyroid profile were done. Bone age was determined in all cases. Growth hormone axis was investigated after excluding other causes. Karyotyping was done in selected cases. Data was analyzed by SPSS 10.0 by descriptive statistics. Mean values were compared using t-test. In this study, the five most common etiological factors in order of frequency were Constitutional Growth Delay (CGD), Familial Short Stature (FSS), malnutrition, coeliac disease and Growth Hormone Deficiency (GHD). In 37.4% of patients, the study revealed normal variants of growth - CGD, FSS or combination of both, 46.7% cases had nonendocrinological and 15.9% had endocrinological etiology. CGD (22.1%) in males and FSS (27%) in females were the most common etiology. GHD was found in 6.1% children and it comprised 38.2% of all endocrinological causes. Children with height falling below 0.4th centile were more likely to have a pathological short stature (79.2%) compared to 39.3% whose height was below 3rd centile but above 0.4th centile (p<0.05). CGD and FSS are most common causes of short stature in boys and girls respectively, whereas, GHD is a relatively uncommon etiology. (author)

    2014-05-01

    Full Text Available Leslie A Sadownik University of British Columbia, Department of Obstetrics and Gynecology, Vancouver, BC, Canada Abstract: Chronic vulvar pain or discomfort for which no obvious etiology can be found, ie, vulvodynia, can affect up to 16% of women. It may affect girls and women across all age groups and ethnicities. Vulvodynia is a significant burden to society, the health care system, the affected woman, and her intimate partner. The etiology is multifactorial and may involve local injury or inflammation, and peripheral and or central sensitization of the nervous system. An approach to the diagnosis and management of a woman presenting with chronic vulvar pain should address the biological, psychological, and social/interpersonal factors that contribute to her illness. The gynecologist has a key role in excluding other causes for vulvar pain, screening for psychosexual and pelvic floor dysfunction, and collaborating with other health care providers to manage a woman's pain. An important component of treatment is patient education regarding the pathogenesis of the pain and the negative impact of experiencing pain on a woman's overall quality of life. An individualized, holistic, and often multidisciplinary approach is needed to effectively manage the woman's pain and pain-related distress.

Etiological factors, lesion localization, symptoms and findings and relationship with prognosis of our patients with cerebellar infarct were investigated in our study. For this purpose, 32 patients were evaluated who were admitted to the Dicle University Medical School Department of Neurology in 1995-2001 hospitalized with the diagnosis of clinically and radiological confirmed cerebellar infarction.All of patients in the study group, 21 (%65.6 were male and 11 (%34.3 female. Age of overall patients ranged between 40 and 75 years with a mean of 57.8±10.2 years. Atherothrombotic infarct was the most frequent reason at the etiologic clinical classification. The most frequently found localization was the posterior inferior cerebellar artery infarct (%50. The leading two risk factors were hypertension (%78.1 and cigarette smoking (%50. The most common sign and symptoms were vertigo (%93.7, vomiting (%75, headache (%68.7 and cerebellar dysfunction findings (%50. The mean duration of hospitalization was 16.3±7.6 days. Overall mortality rate was found to be % 6.2. Finally, the most remarkable risk factors at cerebellar infarct patients are hypertension and atherosclerosis at etiology. We are considering that, controlling of these factors will reduce the appearance frequency of cerebellar infarcts.

  16. Genetic association analysis of ATP binding cassette protein family reveals a novel association of ABCB1 genetic variants with epilepsy risk, but not with drug-resistance.

    Directory of Open Access Journals (Sweden)

    Shabeesh Balan

    Full Text Available Epilepsy constitutes a heterogeneous group of disorders that is characterized by recurrent unprovoked seizures due to widely different etiologies. Multidrug resistance remains a major issue in clinical epileptology, where one third of patients with epilepsy continue to have seizures. Role of efflux transporters in multidrug resistant epilepsy has been attributed to drug-resistant epilepsy although, with discrepant observation in genetic studies. These discrepancies could be attributed to variety of factors such as variable definition of the anti-epileptic drug (AED-resistance, variable epilepsy phenotypes and ethnicities among the studies. In the present study we inquired the role of multidrug transporters ABCB1 and ABCG2 variants in determining AED-resistance and susceptibility to epilepsy in three well-characterized cohorts comprising of mesial temporal lobe epilepsy with hippocampal sclerosis (MTLE-HS (prototype for AED-resistant epilepsy; juvenile myoclonic epilepsy (JME (prototype for AED-responsive epilepsy; and healthy non-epileptic controls, in 738 subjects of Malayalam speaking south Indian ancestry. ABCB1 and ABCG2 variants were not found to be associated with drug resistance when AED-resistant and AED-responsive cohorts were compared. However, a significant association was observed between ABCB1 (C3435T rs1045642 and risk of having epilepsy (MTLE-HS and JME pooled cohort; genotypic p-value = 0.0002; allelic p-value = 0.004. This association was seen persistent with MTLE-HS (genotypic p-value = 0.0008; allelic p-value = 0.004 and also with JME (genotypic p-value = 0.01; allelic p-value = 0.05 cohort individually. In-silico functional prediction indicated that ABCB1 rs1045642 has a deleterious impact on protein coding function and in splicing regulation. We conclude that the ABCB1 and ABCG2 variants do not confer to AED-resistance in the study population. However, ABCB1 rs1045642 increases vulnerability to epilepsy with greater tendency

    2006-01-01

    Full Text Available Epilepsy is recognized as the commonest serious neurological disorder in the world. Women with epilepsy (WWE experience several gender-related physical and social problems. They constitute high obstetric risk because of reduced fertility, risk of seizures during pregnancy, and complications of pregnancy. Hormonal and other factors can alter the pharmacokinetics of antiepileptic drugs (AED during pregnancy and puerperium. Antenatal exposure to AEDs, particularly at higher dosage and in polytherapy, increases the risk of fetal malformation. Recent reports raise the possibility of selective developmental language deficits and neurocognitive deficits with antenatal exposure to AEDs. There are concerns regarding the effect of traces of AEDs that pass to the infant during breast-feeding. The pre conception management is the cornerstone for epilepsy care in WWE. A careful reappraisal of each case should ascertain the diagnosis, the need for continued AED therapy, selection of appropriate AEDs, optimization of the dosage, and prescription of folic acid. During pregnancy, the fetal status needs to be monitored with estimation of serum a-feto-protein and ultrasound screening for malformations. The dosage of AEDs can be adjusted according to clinical requirement and blood levels of AEDs. Several institutions recommend oral vitamin K toward the end of pregnancy when enzyme-inducing AEDs are prescribed because the latter may potentially predispose the new born to hemorrhagic disease, but recent reports indicate that such a risk is practically negligible. WWE who are using enzyme-inducing AEDs (phenobarbitone, primidone, phenytoin, carbamazepine, and oxcarbazepine need to know that these AEDs may lead to failure of oral contraception.

  18. Musical and poetic creativity and epilepsy.

    Science.gov (United States)

    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. The lack of association between recognizable neuropsychiatric disorders and these skills is a gateway to

    2016-01-01

    Background: Mesial temporal lobe epilepsy (TLE) is a remediable epileptic syndrome. About 40% of patients continue to have seizures after standard temporal lobectomy. It has been suggested that some of these patients could actually suffer from a more complex epileptogenic network. Because a few papers have been dedicated to this topic, we decided to write an article updating this theme. Methods: We performed a literature search using the following terminology: “temporal plus epilepsy and networks,” “temporal plus epilepsy,” “orbito-temporal epilepsy,” “temporo-insular epilepsy,” “temporo-parieto-occipital (TPO) epilepsy,” “parieto-temporal epilepsy,” “intracortical evoked potential and temporal plus epilepsy,” “temporal lobe connectivity and epilepsy,” “intracortical evoked potential and epilepsy surgery,” “role of extratemporal structures in TLE,” “surgical failure after temporal lobectomy,” “Diffusion tensor imaging (DTI) and temporal epilepsy,” and “positron emission tomography (PET) in temporal plus lobe epilepsy” in the existing PubMed databases. We searched only English and Spanish literature. Only papers that fit with the above-mentioned descriptors were included as part of the evidence. Other articles were used to reference some aspects of the temporal plus epilepsy. Results: A total of 48 papers from 2334 were revised. The most frequently reported auras in these groups of patients are gustatory hallucinations, vestibular illusions, laryngeal and throat constriction, atypical distribution of somatosensory symptoms (perioral and hands, bilaterally hands paresthesias, trunk and other). The most common signs are tonic posturing, hemifacial twist, and frequent bilateral clonic movements. Interictal electroencephalographic (EEG) patterns exhibit regional and frequently bilateral spikes and/or slow waves. The first ictal electrographic change is mostly regional. It is important to note that the evidence is

    Objectives The burden of epilepsy, in terms of both morbidity and mortality, is likely to vary depending on the etiology (primary [genetic/unknown] vs. secondary [structural/metabolic]) and with the use of antiepileptic drugs (AEDs). We estimated the disability-adjusted life years (DALYs) and modeled the remission rates of active convulsive epilepsy (ACE) using epidemiologic data collected over the last decade in rural Kilifi, Kenya. Methods We used measures of prevalence, incidence, and mortality to model the remission of epilepsy using disease-modeling software (DisMod II). DALYs were calculated as the sum of Years Lost to Disability (YLD) and Years of Life Lost (YLL) due to premature death using the prevalence approach, with disability weights (DWs) from the 2010 Global Burden of Disease (GBD) study. DALYs were calculated with R statistical software with the associated uncertainty intervals (UIs) computed by bootstrapping. Results A total of 1,005 (95% UI 797–1,213) DALYs were lost to ACE, which is 433 (95% UI 393–469) DALYs lost per 100,000 people. Twenty-six percent (113/100,000/year, 95% UI 106–117) of the DALYs were due to YLD and 74% (320/100,000/year, 95% UI 248–416) to YLL. Primary epilepsy accounted for fewer DALYs than secondary epilepsy (98 vs. 334 DALYs per 100,000 people). Those taking AEDs contributed fewer DALYs than those not taking AEDs (167 vs. 266 DALYs per 100,000 people). The proportion of people with ACE in remission per year was estimated at 11.0% in males and 12.0% in females, with highest rates in the 0–5 year age group. Significance The DALYs for ACE are high in rural Kenya, but less than the estimates of 2010 GBD study. Three-fourths of DALYs resulted from secondary epilepsy. Use of AEDs was associated with 40% reduction of DALYs. Improving adherence to AEDs may reduce the burden of epilepsy in this area. PMID:25131901

    To assess the frequency and clinical features of childhood-onset intractable epilepsy caused by the most common mutations in the POLG gene, which encodes the catalytic subunit of mitochondrial DNA polymerase gamma. Children presenting with nonsyndromic intractable epilepsy of unknown etiology but without documented liver dysfunction at presentation were eligible for this prospective, population-based study. Blood samples were analyzed for the three most common POLG mutations. If any of the three tested mutations were found, all the exons and the exon-intron boundaries of the POLG gene were sequenced. In addition, we retrospectively reviewed the notes of patients presenting with intractable epilepsy in which we had found POLG mutations. All available clinical data were collected by questionnaire and by reviewing the medical records. We analyzed 213 blood DNA samples from patients fulfilling the inclusion criteria of the prospective study. Among these, five patients (2.3%) were found with one of the three common POLG mutations as homozygous or compound heterozygous states. In addition, three patients were retrospectively identified. Seven of the eight patients had either raised cerebrospinal fluid (CSF) lactate (n = 3) or brain magnetic resonance imaging (MRI) changes (n = 4) at presentation with intractable epilepsy. Three patients later developed liver dysfunction, progressing to fatal liver failure in two without previous treatment with sodium valproate (VPA). Furthermore, it is worth mentioning that one patient presented first with an autism spectrum disorder before seizures emerged. Mutations in POLG are an important cause of early and juvenile onset nonsyndromic intractable epilepsy with highly variable associated manifestations including autistic features. This study emphasizes that genetic testing for POLG mutations in patients with nonsyndromic intractable epilepsies is very important for clinical diagnostics, genetic counseling, and treatment decisions

    Effective chronic disease management (CDM) requires the ready availability and communication of accurate, clinical disease specific information. Using epilepsy as a probe into CDM, we report on the availability and reliability of clinical information in the primary care records of people with epilepsy (PWE). The medical records of 374 PWE from 53 general practices in the Mid-West region of Ireland were examined. Confirmation of an epilepsy diagnosis by a neurologist was documented for 132 (35%) patients. 282 (75%) patients had no documented evidence of receiving specialist neurology review while 149 (40%) had not been reviewed by their GP in the previous two years for their epilepsy. Significant variation in documentation of epilepsy specific information together with an inadequacy and inconsistency of existing epilepsy services was highlighted.

    2010-01-01

    Although epilepsy is defined by the occurrence of spontaneous epileptic seizures, a large body of evidence indicates that epilepsy is linked to a spectrum behavioral, psychiatric, and cognitive disorders as well as to sudden death. Explanations for these associations include: (1) The effects of structural lesions which may impair the functions subserved by the regions of the brain involved in the lesion. (2) The effects of seizure activity which may begin well before a clinical seizure occurs and may persist long after it is over raising questions about what truly constitutes “interictal.” In addition, encephalopathic effects of epilepsy in infancy during critical periods in development may be particularly severe and potentially irreversible. (3) Shared mechanisms underlying seizures as well as these other disorders in the absence of structural lesions or separate diseases of the CNS. Epidemiological and clinical studies demonstrate the elevated risk of cognitive, psychiatric, and behavioral disorders not just during but also prior to the onset of epilepsy (seizures) itself. These may outlast the active phase of epilepsy as well. The mounting evidence argues strongly for the recognition of epilepsy as part of a spectrum of disorders and against the notion that even uncomplicated epilepsy can a priori be considered benign.

    Objective Functional connectivity (FC) among language regions is decreased in adults with epilepsy compared to controls, but less is known about FC in children with epilepsy. We sought to determine if language FC is reduced in pediatric epilepsy, and examined clinical factors that associate with language FC in this population. Methods We assessed FC during an age-adjusted language task in children with left-hemisphere focal epilepsy (n=19) compared to controls (n=19). Time series data were extracted for three left ROIs and their right homologues: inferior frontal gyrus (IFG), middle frontal gyrus (MFG), and Wernicke's area (WA) using SPM8. Associations between FC and factors such as cognitive performance, language dominance, and epilepsy duration were assessed. Results Children with epilepsy showed decreased interhemispheric connectivity compared to controls, particularly between core left language regions (IFG, WA) and their right hemisphere homologues, as well as decreased intrahemispheric right frontal FC. Increased intrahemispheric FC between left IFG and left WA was a positive predictor of language skills overall, and naming ability in particular. FC of language areas was not affected by language dominance, as the effects remained when only examining study participants with left language dominance. Overall FC did not differ according to duration of epilepsy or age of onset. Significance FC during a language task is reduced in children, similar to findings in adults. In specific, children with left focal epilepsy demonstrated decreased interhemispheric FC in temporal and frontal language connections and decreased intrahemispheric right frontal FC. These differences were present near the onset of epilepsy. Greater FC between left language centers is related to better language ability. Our results highlight that connectivity of language areas has a developmental pattern and is related to cognitive ability. PMID:25516399

    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

    Altered sensory sensitivity is generally linked to seizure-susceptibility in childhood epilepsy but may also be associated to the highly prevalent problems in behavioral adaptation. This association is further suggested by the frequent overlap of childhood epilepsy with autism spectrum disorder (ASD) and attention deficit hyperactivity disorder (ADHD), conditions in which altered behavioral responses to sensory stimuli have been firmly established. A continuum of sensory processing defects due to imbalanced neuronal inhibition and excitation across these disorders has been hypothesizedthat may lead to common symptoms of inadequate modulation of behavioral responses to sensory stimuli. Here, we investigated the prevalence of sensory modulation disorders among children with epilepsy and their relation with symptomatology of neurodevelopmental disorders. We used the Sensory Profile questionnaire to assess behavioral responses to sensory stimuli and categorize sensory modulation disorders in children with active epilepsy (aged 4-17 years). We related these outcomes to epilepsy characteristics and tested their association with comorbid symptoms of ASD (Social Responsiveness Scale) and ADHD (Strengths and Difficulties Questionnaire). Sensory modulation disorders were reported in 49 % of the 158 children. Children with epilepsy reported increased behavioral responses associated with sensory "sensitivity," "sensory avoidance," and "poor registration" but not "sensory seeking." Comorbidity of ASD and ADHD was associated with more severe sensory modulation problems, although 27 % of typically developing children with epilepsy also reported a sensory modulation disorder. Sensory modulation disorders are an under-recognized problem in children with epilepsy. The extent of the modulation difficulties indicates a substantial burden on daily functioning and may explain an important part of the behavioral distress associated with childhood epilepsy.

    Full Text Available The association between neurocysticercosis (NCC and epilepsy is well known and NCC is an important risk factor for epileptic seizures in many Taenia solium-endemic regions of the world. However, while the relationship between NCC and epilepsy is well known, the association between NCC and medically refractory (or surgically remediable epilepsy has received little attention in the past. Our experience and review of the sparse literature available suggests that NCC is causally related to surgically remediable epilepsy albeit uncommonly so and that association derives its underpinnings from several different scenarios: (1 Medically refractory lesional epilepsy, in which seizures arise from the vicinity of the calcified neurocysticercus lesion (CNL, (2 Medically refractory epilepsy with dual pathology type of relationship between the hippocampal sclerosis (HS and CNL in which both have been unequivocally demonstrated to give rise to independent seizures and (3 Mesial temporal lobe epilepsy due to HS with a distantly-located CNL, which is in itself not epileptogenic. A major point of controversy revolves around whether or not there exists a causal association between the CNL and HS. We believe that an association exists between NCC and HS and the most important factor influencing this association is the location of the CNL. Furthermore, NCC is a risk factor for medically-refractory epilepsy and that this might account for a considerable proportion of the intractable epilepsy population in endemic regions; the association has been largely ignored owing to the lack of availability of presurgical work-up facilities in these regions. Finally, from a clinical standpoint of presurgical evaluation, patients with CNL and HS should be evaluated on a case by case basis owing to disparate settings underlying the association.

    The revolution in theory, swift technological developments, and invention of new devices have driven tremendous progress in neurostimulation as a third-line treatment for epilepsy. Over the past decades, neurostimulation took its place in the field of epilepsy as an advanced treatment technique and opened up a new world. Numerous animal studies have proven the physical efficacy of stimulation of the brain and peripheral nerves. Based on this optimistic fundamental research, new advanced techniques are being explored in clinical practice. Over the past century, drawing on the benefits brought about by vagus nerve stimulation for the treatment of epilepsy, various new neurostimulation modalities have been developed to control seizures. Clinical studies including case reports, case series, and clinical trials have been booming in the past several years. This article gives a comprehensive review of most of these clinical studies. In addition to highlighting the advantages of neurostimulation for the treatment of epilepsy, concerns with this modality and future development directions are also discussed. The biggest advantage of neurostimulation over pharmacological treatments for epilepsy is the modulation of the epilepsy network by delivering stimuli at a specific target or the "hub." Conversely, however, a lack of knowledge of epilepsy networks and the mechanisms of neurostimulation may hinder further development. Therefore, theoretical research on the mechanism of epileptogenesis and epilepsy networks is needed in the future. Within the multiple modalities of neuromodulation, the final choice should be made after full discussion with a multidisciplinary team at a presurgical conference. Furthermore, the establishment of a neurostimulation system with standardized parameters and rigorous guidelines is another important issue. To achieve this goal, a worldwide collaboration of epilepsy centers is also suggested in the future.

  14. Occipital lobe seizures and epilepsies.

    Adcock, Jane E; Panayiotopoulos, Chrysostomos P

    2012-10-01

    Occipital lobe epilepsies (OLEs) manifest with occipital seizures from an epileptic focus within the occipital lobes. Ictal clinical symptoms are mainly visual and oculomotor. Elementary visual hallucinations are common and characteristic. Postictal headache occurs in more than half of patients (epilepsy-migraine sequence). Electroencephalography (EEG) is of significant diagnostic value, but certain limitations should be recognized. Occipital spikes and/or occipital paroxysms either spontaneous or photically induced are the main interictal EEG abnormalities in idiopathic OLE. However, occipital epileptiform abnormalities may also occur without clinical relationship to seizures particularly in children. In cryptogenic/symptomatic OLE, unilateral posterior EEG slowing is more common than occipital spikes. In neurosurgical series of symptomatic OLE, interictal EEG abnormalities are rarely strictly occipital. The most common localization is in the posterior temporal regions and less than one-fifth show occipital spikes. In photosensitive OLE, intermittent photic stimulation elicits (1) spikes/polyspikes confined in the occipital regions or (2) generalized spikes/polyspikes with posterior emphasis. In ictal EEG, a well-localized unifocal rhythmic ictal discharge during occipital seizures is infrequent. A bioccipital field spread to the temporal regions is common. Frequency, severity, and response to treatment vary considerably from good to intractable and progressive mainly depending on underlying causes.

    Hippocampal sclerosis (HS) and focal cortical dysplasia (FCD) are among the most common neuropathological findings in those undergoing surgery for refractory mesial temporal lobe epilepsy. Existing data regarding differences among the most recent International League Against Epilepsy (ILAE) HS subtypes remain limited. This study sought to characterize the roles of HS subtype and coexistent FCD. Epilepsy surgery pathologic specimens in 307 cases of temporal lobe epilepsy with HS were reviewed (mean age±SD, 37±15years; 56% women). HS and coexistent FCD were classified according to ILAE guidelines. Medical records were reviewed for data on seizure recurrence and seizure burden (clinical follow-up mean duration ± SD, 5±4years). Cases of typical HS (ILAE type I) predominated (ILAE type Ia: 41%, Ib: 47%, II: 11%, and III: 0.7%]. The HS subtypes shared similar demographic and etiologic characteristics, as well as associated pathology and postoperative seizure outcomes. Individuals with type Ib HS were more likely to remain seizure free at long-term follow-up when compared with other subtypes, and they had a later age of seizure onset. Two hundred forty-three cases (79%) demonstrated FCD within the adjacent temporal lobe. Its presence was associated with a significantly decreased risk of seizure recurrence (P=.02). When present, FCD was predominantly type I (98%). HS subtype does not appear to affect epilepsy surgery outcomes despite some clinical differences between the subgroups. FCD is often observed in association with HS in mesial temporal lobe epilepsy; the finding of FCD was associated with better postoperative outcomes. Copyright © 2017 Elsevier Inc.

    The Managing Epilepsy Well (MEW) Network was established in 2007 by the Centers for Disease Control and Prevention Epilepsy Program to expand epilepsy self-management research. The network has employed collaborative research strategies to develop, test, and disseminate evidence-based, community-based, and e-Health interventions (e-Tools) for epilepsy self-management for people with epilepsy, caregivers, and health-care providers. Since its inception, MEW Network collaborators have conducted formative studies (n=7) investigating the potential of e-Health to support epilepsy self-management and intervention studies evaluating e-Tools (n=5). The MEW e-Tools (the MEW website, WebEase, UPLIFT, MINDSET, and PEARLS online training) and affiliated e-Tools (Texting 4 Control) are designed to complement self-management practices in each phase of the epilepsy care continuum. These tools exemplify a concerted research agenda, shared methodological principles and models for epilepsy self-management, and a communal knowledge base for implementing e-Health to improve quality of life for people with epilepsy. © 2013.

    Positron emission tomography (PET) with [ 18 F]fluoro-D-deoxyglucose (FDG) has been used to detect seizure foci and evaluate surgical resection with localization related epilepsies. However, few investigations have focused on generalized epilepsy in children. To reveal the pathophysiology of generalized epilepsy, we studied 11 patients with generalized epilepsy except West syndrome, and 11 patients with localization related epilepsy without organic disease. The FDG PET was performed by simultaneous emission and transmission scanning. We placed regions of interest (ROI) on bilateral frontal lobe, parietal lobe, occipital lobe, temporal lobe, basal ganglia, thalamus and cerebellum. Standardized uptake value (SUV) was measured and normalized to SUV of ipsilateral cerebellum. Then, we compared the data of generalized epilepsy to those of localization related epilepsy. FDG PET revealed significant interictal glucose hypometabolism in bilateral basal ganglia in generalized epilepsy compared to that in localization related epilepsy (right side: p=0.0095, left side: p=0.0256, Mann-Whitney test). No other region showed any significant difference (p>0.05) between the two groups. These findings indicate that the basal ganglia is involved in the outbreak of generalized seizures or is affected secondarily by the epileptogenicity itself. (author)

    Full Text Available Introduction and objective: The neonatal hearing loss is one of the most common disabilities, with lifelong implications for the child and his family. The implementation of the universal newborn hearing screening and the development in molecular medicine, genetic and integrative neuroscience has perfected the early diagnosis of the hearing loss children and consequently its intervention. With this work, we want to clarify the audiological aspects and causes of the permanent hearing loss diagnosed during the past 20 years. Method: We reviewed retrospectively the records of the children diagnosed with less than 3 years of age of permanent hearing loss, during the period 1994-2015, in a tertiary center. Evaluate the time of home, laterality, type and degree of hearing loss. Depending on the background, genetic testing and other complementary explorations, we present the results of our diagnostic study. Results: In the study-population (n = 183, 71% of the permanent hearing loss > 30 dB HL was diagnosed at birth (congenital. Its main features are the bilaterality (81%, the predominance sensorineural (85% and the grade profound (42% or moderate (30%, more prevalent in the unilateral forms. About the etiologic diagnosis, a 47% of the cases are of origin genetic (29% of which are syndromic, a 25% of cause environmental and a 28% unknown. Discussion: Our results are consistent for the generally accepted distribution of causes, but there are discrepancies in the literature. Despite the different tests used, we had to infer the etiology in 62% of children with hearing loss, finally unknown by 28%. Conclusions: We consider fundamental the monitoring for a consensus standardized etiological protocol that orient in the diagnostic process of hearing loss in children.

    Xerostomia is defined as the complaint of oral dryness. It is a condition that primarily affects older adults and can have a significant negative effect on one's quality of life. Patients with xerostomia often do not have objective signs of hyposalivation. The underlying etiology of xerostomia includes a variety of systemic diseases and local factors. Our aim is to provide a comprehensive review of the differential diagnosis, evaluation, and management of xerostomia. Prompt diagnosis and management can alleviate the clinical manifestations of this debilitating condition. Copyright © 2017 Elsevier Inc. All rights reserved.

    Full Text Available Sexual dysfunction is the impairment or disruption of any of the three phases of normal sexual functioning, including loss of libido, impairment of physiological arousal and loss, delay or alteration of orgasm. Each one of these can be affected by an orchestra of factors like senility, medical and surgical illnesses, medications and drugs of abuse. Non-pharmacological therapy is the main stay in the treatment of sexual dysfunction and drugs are used as adjuncts for a quicker and better result. Management in many of the cases depends on the primary cause. Here is a review of the major etiological factors of sexual dysfunction and its management

    Full Text Available Pediatric acute liver failure (PALF is a complex syndrome with rapid progression, and the cause of PALF is age-dependent. This article analyzes the common causes of PALF in clinical practice, including infection factors, inherited metabolic factors, poisoning and drugs, abnormal perfusion, and autoimmune diseases, among which infection factors are the most common cause. With the improvement in diagnosis and treatment techniques, the diagnostic rate of PALF caused by inherited metabolic diseases and autoimmune diseases keeps increasing. Due to the small number of PALF patients, there lacks experience in etiological diagnosis. This article summarizes related reports, in order to provide a reference for screening the causes of PALF.

    The current study aimed to evaluate the clinical characteristics and outcome of hemispherotomy in children with refractory hemispherical epilepsy. Retrospective analysis of data in twenty one children aged ≤12 years who underwent hemispherotomy and had at least two years post surgery follow-up was performed. Sixteen children underwent Delalande's vertical para-sagittal hemispherotomy (VPH), while lateral peri-insular functional hemispherotomy was performed in the rest. The average age of onset for epilepsy in the study population was 2.9 ± 2.4 years; the average duration of epilepsy was 4.0 ± 2.9 years. The mean age at surgery of the study population was 6.8 ± 2.8 years. Six (28.5%) children were girls. Gliosis due to presumed childhood infarct was most common etiology, observed in 13 (62.0%) of the children, followed by Rasmussen's encephalitis in six (28.5%). There was no significant difference between the surgery groups for the reported acute post operative seizures (APOS) (20.0% vs. 25.0%; p = 1.000). At last follow up 90.5% patients were seizure free; there was no difference between the groups for seizure freedom (60.0% vs. 87.5%; p = 0.228). When analyzed for outcome between the etiologies, seizure freedom was similar for gliosis due to infarct (76.9%), Rassmussens encephalitis (83.3%) and malformations of cortical development (MCD) (100.0%). Moreover, improved quality of life in epilepsy (QOLIE) scores was observed in 80.0% of the lateral peri-insular functional hemispherotomy group and 87.5% children in VPH group at the last follow-up. Gliosis due to presumed childhood infarct was the leading cause of medically refractory epilepsy caused by hemispheric lesions in the current study. Encouragingly, hemispherotomy offers seizure freedom (in 90.5% patients) and improvement in QOLIE scores at two years follow up. Copyright © 2015 IJS Publishing Group Ltd. Published by Elsevier Ltd.

    PURPOSE: To validate the diagnosis of epilepsy in the Danish National Hospital Register. METHODS: We randomly selected 200 patients registered with epilepsy in the Danish National Hospital Register between 1977 and 2002 and validated the diagnosis according to the guidelines developed...... by the International League Against Epilepsy. RESULTS: We reviewed the medical records of 188 (94%) persons from 57 departments at 41 hospitals. The epilepsy diagnoses were confirmed in 153 patients, providing a positive predictive value for epilepsy of 81% (95% confidence interval (95% CI): 75-87%). Among the 35...... for syndrome classification was 60% (95% CI: 44-74%) for epilepsy with complex focal seizures and 35% (95% CI: 22-51%) for primary generalized epilepsy. CONCLUSION: The validity of the epilepsy diagnoses in the Danish National Hospital Register has a moderate to high positive predictive value for epilepsy...

    This is the first of a two-part primer on the genetics of the epilepsies within the Genetic Literacy Series of the Genetics Commission of the International League Against Epilepsy. In Part 1, we cover the foundations of epilepsy genetics including genetic epidemiology and the range of genetic variants that can affect the risk for developing epilepsy. We discuss various epidemiologic study designs that have been applied to the genetics of the epilepsies including population studies, which provide compelling evidence for a strong genetic contribution in many epilepsies. We discuss genetic risk factors varying in size, frequency, inheritance pattern, effect size, and phenotypic specificity, and provide examples of how genetic risk factors within the various categories increase the risk for epilepsy. We end by highlighting trends in epilepsy genetics including the increasing use of massive parallel sequencing technologies. Wiley Periodicals, Inc. © 2016 International League Against Epilepsy.

    To investigate the possible influence of risk factors on seizure outcome after surgery for drug-resistant temporal lobe epilepsy (TLE) and mesial temporal sclerosis (MTS). This retrospective study recruited patients with drug-resistant MTS-TLE who underwent epilepsy surgery at Jefferson Comprehensive Epilepsy Center and were followed for a minimum of 1 year. Patients had been prospectively registered in a database from 1986 through 2014. After surgery outcome was classified into 2 groups: seizure-free or relapsed. The possible risk factors influencing long-term outcome after surgery were investigated. A total of 275 patients with MTS-TLE were studied. Two thirds of the patients had Engel's class 1 outcome and 48.4% of the patients had sustained seizure freedom, with no seizures since surgery. Patients with a history of tonic-clonic seizures in the year preceding surgery were more likely to experience seizure recurrence (odds ratio, 2.4; 95% confidence interval 1.19-4.80; P = 0.01). Gender, race, family history of epilepsy, history of febrile seizure, history of status epilepticus, duration of disease before surgery, intelligence quotient, and seizure frequency were not predictors of outcome. Many patients with drug-resistant MTS-TLE respond favorably to surgery. It is critical to distinguish among different types and etiologies of TLE when predicting outcome after surgery.

    Objective: To study the different patterns of hippocampal atrophy by MRI segmental analysis and to investigate the etiology and pathogenesis of temporal lobe epilepsy. Methods: GE 1.5 T Signa Horizon LX MRI scanner was used. Oblique coronal T 1 weighted images perpendicular to the long axis of the hippocampus were obtained. The mesial temporal structures were divided into four parts: the amygdala, hippocampal head, body and tail. MRI patterns of atrophy in 50 patients with histologically confirmed hippocampal sclerosis were investigated by MRI volumetric measurement and segmental analysis, and the differences of clinical features and surgical outcome in different groups were compared. Results: Diffuse hippocampal atrophy was found in 22 of 50 patients (44%), 5 of the 50 patients (10%) showed diffuse atrophy involving both the amygdala and hippocampus. 20 of the 50 patients (40%) had hippocampal focal atrophy and 8 of 50 patients (16%) had no obvious atrophy. 38 of 50 (76%) hippocampal sclerosis had atrophy in the hippocampal body, 29 of 50 (58%) had hippocampal head atrophy, 24 of 50 (48%) had hippocampal tail atrophy, and the least involved part was the amygdala (16%, 8/50). 10 patients who had normal hippocampal volume showed focal hippocampal atrophy by segmental analysis. Various patterns of hippocampal atrophy were found to be statistically related to the duration of epilepsy, the frequency of seizure and the outcome of surgery, respectively (P 0.05). Conclusion: MRI segmental analysis can improve the diagnostic sensitivity of temporal lobe epilepsy and help to investigate its etiology and pathogenesis. (author)

    Full Text Available Cognitive and mental disorders often occur in patients with epilepsy and significantly reduce the quality of life of patients and their families. Approximately in 35 % of patients, despite treatment, various violations of intelligence, behavior, affective sphere of different degree of seve rity are preserved. In general, mental (affective, anxious and psychotic disorders occur in epilepsy 2–3 times more often than in the general population. The most common is depression: the occurrence of depression and anxiety in epilepsy varies from 20 to 55 % (and more than 50 % of patients with refractory focal epilepsy, especially epilepsy of the temporal lobe of the brain. Children are a particularly vulnerable category of patients: in addition to persistent intellectual disabilities (mental retardation, they may have specific impairments in the form of mental and speech development delay, learning difficulties, attention deficit hyperactivity disorder.Causes of cognitive and mental disorders in epilepsy can directly be the factor underlying epilepsy (genetic disease, structural brain defect, etc., epileptic seizures, interictal epileptiform activity, side effects of antiepileptic drugs (AED. In many cases, a patient with epilepsy combines several of these causes, and it is often difficult to determine which one cause is leading. The contribution of specific factors is difficult to estimate, because different factors can have an independent different effect on cognitive impairment. Some of causes underlying cognitive and mental disorders in epilepsy can be influenced and thus reduce the existing risk. Such measures include early diagnosis and effective adequate treatment of epileptic encephalopathy, as early as possible control of seizures, justified appointment of AED in children with cognitive impairment of unknown etiology and frequent epileptiform discharges on the electroencephalogram, careful monitoring of cognitive side effects of AED and

    AIM To investigate different etiologies and management of the rhabdomyolysis in children. METHODS Eight pediatric rhabdomyolysis cases who applied to the Dokuz Eylul University Faculty of Medicine Department of Pediatric Nephrology with different etiologies between January 2004 and January 2012 were evaluated in terms of age, gender, admission symptoms, physical examination findings, factors provoking rhabdomyolysis, number of rhabdomyolysis attacks, laboratory results, family history and the final diagnosis received after the treatment. RESULTS Average diagnosis ages of eight cases were 129 (24-192) ± 75.5 mo and five of them were girls. All of them had applied with the complaint of muscle pain, calf pain, and dark color urination. Infection (pneumonia) and excessive physical activity were the most important provocative factors and excessive licorice consumption was observed in one case. In 5 cases, acute kidney injury was determined and two cases needed hemodialysis. As a result of the further examinations; the cases had received diagnoses of rhabdomyolysis associated with mycoplasma pneumoniae, sepsis associated rhabdomyolysis, licorice-induced hypokalemic rhabdomyolysis, carnitine palmitoyltransferase II deficiency, very long-chain acyl-CoA dehydrogenase deficiency, congenital muscular dystrophy and idiopathic paroxysmal rhabdomyolysis (Meyer-Betz syndrome). CONCLUSION It is important to distinguish the sporadic and recurrent rhabdomyolysis cases from each other. Recurrent rhabdomyolysis cases should follow up more regardful and attentive. PMID:29184760

    2018-06-01

    Childhood obesity is an important public health issue worldwide. Urbanization, sedentary lifestyle and change in food habits are the chief reasons behind this pandemic. In a small proportion of children, obesity is the result of endocrine, syndromic or monogenic causes. The present paper summarizes the methods, definitions and cut-offs for identification of obesity in children. We have briefly reviewed the various techniques used for estimation of body fat in children and the cut-offs for defining obesity based on body fat percentage, and the reference curves based on body mass index and waist circumference. The etiology of obesity in children, including individual behaviors, macro- and micro-environmental influences, and endocrine causes have been discussed, and an approach to etiological assessment of obese children has been presented. Special emphasis has been laid on clinical pointers that suggest the presence of syndromic, endocrine or monogenic forms of obesity, such as, short stature, dysmorphism, neurocognitive impairment and early age at onset.

    Over the last decade, the National Wildlife Health Center of the United States Geological Survey has documented various largescale mortalities of birds caused by infectious and non-infectious disease agents. Some of these mortality events have unusual or unidentified etiologies and have been recurring. While some of the causes of mortalities have been elucidated, others remain in various stages of investigation and identification. Two examples are discussed: 1) Leyogonimus polyoon (Class: Trematoda), not found in the New World until 1999, causes severe enteritis and has killed over 15 000 American Coot Fulica americana in the upper mid-western United States. The geographic range of this parasite within North America is predicted to be limited to the Great Lakes Basin. 2) In the early 1990s, estimates of up to 6% of the North American population of the Eared Grebe Podiceps nigricollis died at Salton Sea, California, with smaller mortalities occurring throughout the 1990s. Birds were observed to have unusual preening behaviour, and to congregate at freshwater drains and move onto land. Suggested etiologies included interactions of contaminants, immuno-suppression, an unusual form of a bacterial disease, and an unknown biotoxin. During studies carried out from 2000 to 2003, Eared Grebe mortality did not approach the level seen in the early 1990s and, although bacteria were identified as minor factors, the principal cause of mortality remains undetermined. The potential population impact of these emerging and novel disease agents is currently unknown.

    Emperor John III Ducas Vatatzes (ruled from 1222-1254) and his son Theodore II Lascaris (ruled from 1254-1258) both suffered from epilepsy. On his journeys to Nicaea, St Sava visited emperors Theodore I Lascaris (ruled from 1204-1222) and John II Vatatzes, who richly rewarded him, which was probably of crucial importance for the foundation of hospitals in the Monastery of Hilandar and the Monastery of Studenica These hospitals had special departments for the treatment of patints with epilepsy. According to researches conducted up-to-date, these departments are considered to be the oldest institutions for epilepsy treatment. Monastery hospitals in the West served primarily as a shelter for the poor and patients with chronic incurable diseases. The development of Serbian monastery hospitals was a long process and it included institutions that lasted for a long time (for over two centuries) in which, among others, those affected by epilepsy were cured.

    OBJECTIVE: To assess the influence of parental rheumatoid arthritis (RA) on risk of epilepsy. METHODS: We performed a nationwide cohort study including all singletons born in Denmark from 1977 to 2008 (n = 1,917,723) through individual linkage to nationwide Danish registries. The children were...... followed for an average of 16 years. Main outcome measures were adjusted hazard ratios (HRs) for epilepsy with onset in early childhood (29 days-4 years), late childhood (5-15 years), adolescence/adulthood (≥15 years), and at any age until the end of follow-up (December 31, 2010). RESULTS: Compared...... to unexposed children, children exposed to maternal RA had an increased risk of early and late childhood epilepsy (adjusted HRs 1.34 [95% confidence interval (CI) 1.13-1.60] and 1.26 [95% CI 1.13-1.41]), while children exposed to maternal RA had no increased risk of epilepsy in adolescence/adulthood (HR 1...

    We performed principal component analysis (PCA) of the Epilepsy Foundation Concerns Index scale in 189 patients undergoing evaluation for epilepsy surgery. We identified a five-factor solution in which there were no varimax-rotated factors consisting of fewer than two questions. Factor 1 reflects affective impact on enjoyment of life, Factor 2 reflects general autonomy concerns, Factor 3 reflects fear of seizure recurrence, Factor 4 reflects concern of being a burden to one's family, and Factor 5 reflects a perceived lack of understanding by others. Multiple regression using the Quality of Life in Epilepsy--89 question version; Minnesota Multiphasic Personality Inventory--2; Wechsler Adult Intelligence Scale--third edition; and verbal and visual memory tests as predictors demonstrated a different pattern of association with the factor and summary scores. We conclude that the Epilepsy Foundation Concerns Index is multidimensional, and using a global score based on all items may mask specific concerns that may be relevant when applied to individual patients.

  20. Epilepsy: legal discrimination from negative to positive.

    Mani, K S

    1997-01-01

    Indian law equates epilepsy with temporary insanity and also prohibits a legally valid marriage for a person with epilepsy with inherent risk of divorce. This absurd law, unique to India and possibly Brazil, must be excised in toto. Repeated petitions, by the Indian Epilepsy Association, to the Federal Government, have resulted in only vague assurances and alternate methods are under consideration. There are no legal impediments to education or work. Strict regulations against driving have yielded place to lax rules wherein a person can drive a vehicle, even after a recent fit, provided he gets a certificate from any registered medical practitioner. The nascent medical insurance specifically excludes epilepsy from its ambit. The cost of anti-epileptic drugs includes a 40% tax akin to Value Added Tax in the West. We must consider the impact of these legal impediments on the social fabric of the individual in his/her milieu and vis-a-vis priorities in national development.

    2017-04-01

    Temporal lobe resection is the most prevalent epilepsy surgery procedure. However, there is no consensus on the best surgical approach to treat temporal lobe epilepsy. Complication rates are low and efficacy is very high regarding seizures after such procedures. However, there is still ample controversy regarding the best surgical approach to warrant maximum seizure control with minimal functional deficits. We describe the most frequently used microsurgical techniques for removal of both the lateral and mesial temporal lobe structures in the treatment of medically intractable temporal lobe epilepsy (TLE) due to mesial temporal sclerosis (corticoamygdalohippocampectomy and selective amygdalohippocampectomy). The choice of surgical technique appears to remain a surgeon's preference for the near future. Meticulous surgical technique and thorough three-dimensional microsurgical knowledge are essentials for obtaining the best results.

    Pharmacogenetics (PGX) is the study of how genetic variants influence individual responses to drugs. Although numerous candidate gene studies in epilepsy PGX have been published, to date only two validated associations exist: the association of the *2 and *3 alleles of CYP2C9 with phenytoin metabolism and the association of HLA-B*1502 with serious hypersensitivity reactions to carbamazepine. The advent of novel technologies such as genomewide association studies and next generation sequencing will likely lead to the identification of additional genetic biomarkers. The potential benefits of epilepsy PGX are multiple: epilepsy treatment in individual patients would become more rationalized, clinical trials could be stratified according to patients' genetic profiles and novel therapeutic pathways may be uncovered. Ultimately, it is hoped that PGX will improve the quality of life for people suffering from epilepsy worldwide. © 2013 médecine/sciences – Inserm / SRMS.

  3. Aging models of acute seizures and epilepsy.

    Kelly, Kevin M

    2010-01-01

    Aged animals have been used by researchers to better understand the differences between the young and the aged brain and how these differences may provide insight into the mechanisms of acute seizures and epilepsy in the elderly. To date, there have been relatively few studies dedicated to the modeling of acute seizures and epilepsy in aged, healthy animals. Inherent challenges to this area of research include the costs associated with the purchase and maintenance of older animals and, at times, the unexpected and potentially confounding comorbidities associated with aging. However, recent studies using a variety of in vivo and in vitro models of acute seizures and epilepsy in mice and rats have built upon early investigations in the field, all of which has provided an expanded vision of seizure generation and epileptogenesis in the aged brain. Results of these studies could potentially translate to new and tailored interventional approaches that limit or prevent the development of epilepsy in the elderly.

  4. Autosomal dominant cortical tremor, myoclonus and epilepsy.

    Striano, Pasquale; Zara, Federico

    2016-09-01

    The term 'cortical tremor' was first introduced by Ikeda and colleagues to indicate a postural and action-induced shivering movement of the hands which mimics essential tremor, but presents with the electrophysiological findings of cortical reflex myoclonus. The association between autosomal dominant cortical tremor, myoclonus and epilepsy (ADCME) was first recognized in Japanese families and is now increasingly reported worldwide, although it is described using different acronyms (BAFME, FAME, FEME, FCTE and others). The disease usually takes a benign course, although drug-resistant focal seizures or slight intellectual disability occur in some cases. Moreover, a worsening of cortical tremor and myoclonus is common in advanced age. Although not yet recognized by the International League Against Epilepsy (ILAE), this is a well-delineated epilepsy syndrome with remarkable features that clearly distinguishes it from other myoclonus epilepsies. Moreover, genetic studies of these families show heterogeneity and different susceptible chromosomal loci have been identified.

  9. FUNCTION IN BIOLOGY: ETIOLOGICAL AND ORGANIZATIONAL PERSPECTIVES

    Directory of Open Access Journals (Sweden)

    Charbel Niño El-Hani

    2009-10-01

    Full Text Available ABSTRACT. In this paper, we argue for a taxonomy of approaches to function based on different epistemological perspectives assumed with regard to the treatment of this central concept in the life sciences. We distinguish between etiological and organizational perspectives on function, analyzing two distinct theories related to each perspective: Wright’s selectionist etiological approach and Godfrey-Smith’s modern history theory of functions, in the case of the etiological perspective; and Cummins’ functional analysis and Collier’s interactivist approach to function, among organizational accounts. We explain differences and similarities between these theories and the broader perspectives on function, arguing for a particular way of understanding the consensus without unity in debates about function. While explaining the accounts of function, we also deal with the relationship between this concept and other important biological concepts, such as adaptation, selection, complexity, and autonomy. We also advance an argument for the limits and prospects of the explanatory role of function in evolution. By arguing that changes in functionality are always grounded on changes in systems’ organization, we show that function can never explain the origins of traits. Nevertheless, it can explain the spread of traits in populations, but only when we are dealing with functionally novel traits. Finally, we stress that organizational accounts of function are needed to understand how new functions appear by means of changes in systems’ organization. KEYWORDS: Function; Teleology; Explanation; Etiology; Organization.   RESUMEN. En este artículo, argumentamos a favor de una taxonomía de abordajes sobre función basada en diferentes perspectivas epistemológicas a cerca del tratamiento de este concepto central en las ciencias de la vida.

    Strzelczyk, Adam; Reese, Jens Peter; Dodel, Richard; Hamer, Hajo M

    2008-01-01

    The objective of this review was to overview published cost-of-illness (COI) studies of epilepsy and their methodological approaches. Epilepsy imposes a substantial burden on individuals and society as a whole. The mean prevalence of epilepsy is estimated at 0.52% in Europe, 0.68% in the US, and peaks up to 1.5% in developing countries. Estimation of the economic burden of epilepsy is of pivotal relevance to enable a rational distribution of healthcare resources. This is especially so with the introduction of the newer antiepileptic drugs (AEDs), the marketing of vagal-nerve stimulators and the resurgence of new surgical treatment options, which have the potential to considerably increase the costs of treating epilepsy.A systematic literature review was performed to identify studies that evaluated direct and indirect costs of epilepsy. Using a standardized assessment form, information on the study design, methodological framework and data sources were extracted from each publication and systematically reported. We identified 22 studies worldwide on costs of epilepsy. The majority of the studies reflected the costs of epilepsy in Europe (three studies each for the UK and Italy, one study each for Germany, the Netherlands, Switzerland, France and the EU) and the US (four studies), but studies were also available from India (two), Hong Kong, Oman, Burundi, Chile and Mexico. The studies utilized different frameworks to evaluate costs. All used a bottom-up approach; however, only 12 studies (55%) evaluated direct as well as indirect costs. The range for the mean annual direct costs lay between 40 International Dollar purchasing power parities (PPP-$) in rural Burundi and PPP-$4748 (adjusted to 2006 values) in a German epilepsy centre. Recent studies suggest AEDs are becoming the main contributor to direct costs. The mean indirect costs ranged between 12% and 85% of the total annual costs. Epilepsy is a cost-intensive disorder.

Median knowledge score about epilepsy was 5 (out of 13, while median attitude score was 10 (out of 15. Both knowledge and attitude median scores were significantly higher in senior teachers with longer teaching experience and in respondents who dealt with a person with epilepsy. There was significant association between knowledge score and attitude score (p<0.01. Logistic regression showed that significant variables, independently associated with poor knowledge after adjusting for possible confounders, were not having a family member with epilepsy (p=0.009, unawareness of life circumstances of persons with epilepsy (p=0.048, and a poor attitude score (p<0.001. Conclusion. School teachers in Kuwait have relatively poor knowledge about epilepsy but have positive attitudes toward students with epilepsy. A number of historical and stigmatizing ideas about epilepsy still exist. It is recommended to provide teachers with information about handling seizures in the educational setting through development and implementation of epilepsy education programs.

  12. Polycystic Ovary Syndrome in Patients with Epilepsy

    OpenAIRE

    Goltz, Christoph Freiherr von der

    2010-01-01

    Epilepsy has been associated with an increased frequency of reproductive endocrine disorders including polycystic ovary syndrome (PCOS). Some study groups claim that epilepsy itself plays a pathogenic role, whereas others propose that PCOS may be attributable to the use of antiepileptic drugs (AEDs), particularly sodium valproate (VPA). Estimates regarding the prevalence of PCOS in this patient group vary, among other reasons, because of different definitions of PCOS. The aim of the present c...

    The contribution of MR imaging in patients with drug-resistant epilepsy considered for surgical therapy is discussed. In this review we focus on: (a) focal abnormalities (mesial temporal sclerosis, focal migration disorders, hamartomatous lesions and low-grade tumours, phakomatosis and vascular malformations) associated with therapy-resistant partial epilepsy, requiring resective surgery; (b) abnormalities leading to generalized seizures that require more drastic surgical procedures, such as callosotomy and functional hemispherectomy; and (c) localisation of implanted depth-electrodes.

    2003-04-01

    The results of epidemiologic investigations have clearly indicated that the development of lipodystrophy is multifactorial. Factors related to HIV infection, hormonal influences, mitochondrial dysfunction, cytokine activation related to immune reconstitution, and individual genetic predisposition all have been hypothesized as etiologic. Recent studies suggest that immune dysregulation rather than HIV infection per se may be the predominant factor in the development of lipodystrophy.

    2017-10-01

    Approximately 25 million individuals older than age 15 identify as transgender, representing about 0.3-0.9% of the world's population. The aim of this paper is to identify and describe important medical and social considerations facing transgender persons with epilepsy. We performed literature searches on the following terms: transgender AND epilepsy, transgender AND neurology, gender dysphoria AND epilepsy, gender dysphoria AND neurology. We also performed literature searches for common feminizing or masculinizing treatment regimens, and searched for interactions of those treatment regimens with antiepileptic drugs (AEDs) and with seizures. There are multiple bidirectional interactions between AEDs and the commonly used treatments for aligning external sex characteristics with identified gender. The scope of the transgender population with epilepsy remains to be elucidated. Transgender patients with epilepsy face significant social and medical challenges. Interactions between medical gender-affirming treatments and AEDs are common, and management must depend on knowledge of these interactions to provide appropriate treatment.

  18. Neurobehavioral comorbidities of epilepsy: Role of inflammation.

    Science.gov (United States)

    Mazarati, Andrey M; Lewis, Megan L; Pittman, Quentin J

    2017-07-01

    Epilepsy is associated with a high incidence of comorbid neurologic and psychiatric disorders. This review focuses on the association of epilepsy with autism spectrum disorder (ASD) and depression. There is high concordance of these behavioral pathologies with epilepsy. We review data that unambiguously reveal that epilepsy, ASD, and depression are associated with elevated brain inflammatory markers and that these may interact with serotoninergic pathways. Interference with inflammatory pathways or actions can reduce the severity of seizures, depression, and ASD-like behavior. Inflammation in the brain can be induced by seizure activity as well as by behavioral, environmental, and physiologic stressors. Furthermore, induction of inflammation at an early time point during gestation and in early neonatal life can precipitate both an ASD-like phenotype as well as a more excitable brain. It appears likely that priming of the brain due to early inflammation could provide a means by which subsequent inflammatory processes associated with epilepsy, ASD, and depression may lead to comorbidity.

    Full Text Available Laura M Borgelt,1 Felecia M Hart,2 Jacquelyn L Bainbridge2 1Departments of Clinical Pharmacy and Family Medicine, 2Departments of Clinical Pharmacy and Neurology, University of Colorado Anschutz Medical Campus, Skaggs School of Pharmacy and Pharmaceutical Sciences, Aurora, CO, USA Abstract: In the US, more than one million women with epilepsy are of childbearing age and have over 20,000 babies each year. Patients with epilepsy who become pregnant are at risk of complications, including changes in seizure frequency, maternal morbidity and mortality, and congenital anomalies due to antiepileptic drug exposure. Appropriate management of epilepsy during pregnancy may involve frequent monitoring of antiepileptic drug serum concentrations, potential preconception switching of antiepileptic medications, making dose adjustments, minimizing peak drug concentration with more frequent dosing, and avoiding potentially teratogenic medications. Ideally, preconception planning will be done to minimize risks to both the mother and fetus during pregnancy. It is important to recognize benefits and risks of current and emerging therapies, especially with revised pregnancy labeling in prescription drug product information. This review will outline risks for epilepsy during pregnancy, review various recommendations from leading organizations, and provide an evidence-based approach for managing patients with epilepsy before, during, and after pregnancy.

  20. Temporal Lobe Epilepsy Surgery Failures: A Review

    Science.gov (United States)

    Harroud, Adil; Bouthillier, Alain; Weil, Alexander G.; Nguyen, Dang Khoa

    2012-01-01

    Patients with temporal lobe epilepsy (TLE) are refractory to antiepileptic drugs in about 30% of cases. Surgical treatment has been shown to be beneficial for the selected patients but fails to provide a seizure-free outcome in 20–30% of TLE patients. Several reasons have been identified to explain these surgical failures. This paper will address the five most common causes of TLE surgery failure (a) insufficient resection of epileptogenic mesial temporal structures, (b) relapse on the contralateral mesial temporal lobe, (c) lateral temporal neocortical epilepsy, (d) coexistence of mesial temporal sclerosis and a neocortical lesion (dual pathology); and (e) extratemporal lobe epilepsy mimicking TLE or temporal plus epilepsy. Persistence of epileptogenic mesial structures in the posterior temporal region and failure to distinguish mesial and lateral temporal epilepsy are possible causes of seizure persistence after TLE surgery. In cases of dual pathology, failure to identify a subtle mesial temporal sclerosis or regions of cortical microdysgenesis is a likely explanation for some surgical failures. Extratemporal epilepsy syndromes masquerading as or coexistent with TLE result in incomplete resection of the epileptogenic zone and seizure relapse after surgery. In particular, the insula may be an important cause of surgical failure in patients with TLE. PMID:22934162

    Literature, cinema and television have often portrayed stereotypical images of people that have epilepsy and have helped foster false beliefs about the disease. To examine the image of epilepsy presented by literature, cinema and television over the years. Epilepsy has frequently been portrayed in literary works, films and television series, often relating it with madness, delinquency, violent behaviours or possession by the divine or the diabolical, all of which has helped perpetuate our ancestral beliefs. The literary tales and the images that appear in films and on television cause an important emotional impact and, bearing in mind that many people will only ever see an epileptic seizure in a film or in a TV series or might gain some information about the disorder from a literary text, what they see on the screen or read in the novels will be their only points of reference. Such experiences will therefore mark the awareness and knowledge they will have about epilepsy and their attitudes towards the people who suffer from it. Novels and films are fiction, but it is important to show realistic images of the disease that are no longer linked to the false beliefs of the past and which help the general public to have a more correct view of epilepsy that is free from prejudices and stereotypes. Literature, cinema and television have often dealt with the subject of epilepsy, sometimes realistically, but in many cases they have only helped to perpetuate false beliefs about this disease.

    Ideal epilepsy surgery would eliminate seizures without causing any functional deficits. The aim of the present study was to assess seizure outcomes and complications after epilepsy surgery in children with intractable epilepsy. Data obtained in 134 children (75 boys and 59 girls) age 17 years or younger who underwent epilepsy surgery at Seoul National University Children's Hospital between 1993 and 2005 were retrospectively reviewed. Epilepsy surgery included temporal resection (59 cases), extratemporal resection (56 cases), functional hemispherectomy (7 cases), callosotomy (9 cases), multiple subpial transection (1 case), and disconnection of a hamartoma (2 cases). The mean follow-up duration was 62.3 months (range 12-168 months). The overall seizure-free rate was 69% (93 of 134 cases). The seizure-free rate was significantly higher in children who underwent temporal resection than in those in whom extratemporal resection was performed (88 vs 55%, p surgery is an effective and safe therapeutic modality in childhood. In children with extratemporal epilepsy, more careful interpretation of clinical and investigative data is needed to achieve favorable seizure outcome.

    Thyroid hormones (THs) L-thyroxine and L-triiodothyronine, primarily known as metabolism regulators, are tyrosine-derived hormones produced by the thyroid gland. They play an essential role in normal central nervous system development and physiological function. By binding to nuclear receptors and modulating gene expression, THs influence neuronal migration, differentiation, myelination, synaptogenesis and neurogenesis in developing and adult brains. Any uncorrected THs supply deficiency in early life may result in irreversible neurological and motor deficits. The development and function of GABAergic neurons as well as glutamatergic transmission are also affected by THs. Though the underlying molecular mechanisms still remain unknown, the effects of THs on inhibitory and excitatory neurons may affect brain seizure activity. The enduring predisposition of the brain to generate epileptic seizures leads to a complex chronic brain disorder known as epilepsy. Pathologically, epilepsy may be accompanied by mitochondrial dysfunction, oxidative stress and eventually dysregulation of excitatory glutamatergic and inhibitory GABAergic neurotransmission. Based on the latest evidence on the association between THs and epilepsy, we hypothesize that THs abnormalities may contribute to the pathogenesis of epilepsy. We also review gender differences and the presumed underlying mechanisms through which TH abnormalities may affect epilepsy here. Copyright © 2015 British Epilepsy Association.

  4. EPILEPSY IN ELDERLY PATIENTS (DIAGNOSTIC FEATURES

    Directory of Open Access Journals (Sweden)

    S. A. Gulyaev

    2014-01-01

    Full Text Available Physicians frequently consider that epilepsy is a disease in children and young adults; however, its incidence in elderly patients is not lower and commonly higher than those among children and young people. Among the causes of epilepsy in elderly patients, there is a predominance of acute and chronic cerebral circulatory disorders (50 % of all cases. Other causes of epilepsy (neurodegenerative processes, tumors, etc. are rarely encountered in the elderly. However, there is actually no real pattern of incidence of epilepsy in the elderly since the diversity and features of its clinical manifestations in these patients, as well as difficulties in describing their status make the diagnosis of the disease very hard in this category of patients. Seizures without loss of consciousness, which are especially associated with the development of transient muscle tone disorders and autonomic dysfunction, are commonly regarded as benign vertigo, autonomic or mental disorders. This study has indicated that the development of epilepsy in the elderly, which results from cerebrovascular and neurodegenerative pathology, is not a rare, but relatively common neurological disorder. By taking into account the aging tendency in economically developed countries, the increasing number of elderly patients with epilepsy is an important medical and economic problem that calls for in-depth investigation, timely diagnosis,and treatment.

  5. History of epilepsy: nosological concepts and classification.

    Science.gov (United States)

    Wolf, Peter

    2014-09-01

    The purpose of this review is to provide insight into the development of the nosological views of the epilepsies, from prehistoric times to the present, and highlight how these views are reflected by terminology and classification. Even the earliest written documents reveal awareness that there are multiple forms of epilepsy, and it is surprising that they should be included under the same disease concept, perhaps because the generalised tonic-clonic seizure served as a common denominator. The Hippocratic doctrine that the seat of epilepsy is in the brain may be rooted in earlier knowledge of traumatic seizures. Galenus differentiated cases where the brain was the primary site of origin from others where epilepsy was concomitant with illness in other parts of the body. This laid the fundament for the distinction between idiopathic and symptomatic epilepsies, the definition of which changed considerably over time. The description of the multiple seizure types as they are known at present started in the late 18th century. Attempts to classify seizure types began in the late 19th century, when Jackson formulated a comprehensive pathophysiological definition of epilepsy. Electroencephalography supported a second dichotomy, between seizures with localised onset and others with immediate involvement of both hemispheres which became known as "generalised". In recent years, advanced methods of studying brain function in vivo, including the generation of both spontaneous and reflex epileptic seizures, have revolutionised our understanding of focal and "generalised" human ictogenesis. Both involve complex neuronal networks which are currently being investigated.

    Full Text Available Abstract Background Left ventricular hypertrabeculation/noncompaction (LVHT is a cardiac abnormality of unknown etiology which has been described in children as well as in adults with and without chromosomal aberrations. LVHT has been reported in association with various cardiac and extracardiac abnormalities like epilepsy and facial dysmorphism. Case presentation A unique combination of LVHT, atrial septal defect, pulmonary valve stenosis, aortic stenosis, epilepsy and minor facial anomalies is presented in a 5.5 years old girl. Microarray-based genomic hybridization (array-CGH detected six previously not described copy number variants (CNVs inherited from a clinically unaffected father and minimally affected mother, thus, most likely, not clinically significant but rare benign variants. Conclusions Despite this complex phenotype de novo microdeletions or microduplications were not detected by array CGH. Further investigations, such as whole exome sequencing, could reveal point mutations and small indels as the possible cause.

    Idiopathic epilepsies (IEs) are a group of disorders characterized by recurrent seizures in the absence of detectable brain lesions or metabolic abnormalities. IEs include common disorders with a complex mode of inheritance and rare Mendelian traits suggesting the occurrence of several alleles with variable penetrance. We previously described a large family with a recessive form of idiopathic epilepsy, named familial infantile myoclonic epilepsy (FIME), and mapped the disease locus on chromosome 16p13.3 by linkage analysis. In the present study, we found that two compound heterozygous missense mutations (D147H and A509V) in TBC1D24, a gene of unknown function, are responsible for FIME. In situ hybridization analysis revealed that Tbc1d24 is mainly expressed at the level of the cerebral cortex and the hippocampus. By coimmunoprecipitation assay we found that TBC1D24 binds ARF6, a Ras-related family of small GTPases regulating exo-endocytosis dynamics. The main recognized function of ARF6 in the nervous system is the regulation of dendritic branching, spine formation, and axonal extension. TBC1D24 overexpression resulted in a significant increase in neurite length and arborization and the FIME mutations significantly reverted this phenotype. In this study we identified a gene mutation involved in autosomal-recessive idiopathic epilepsy, unveiled the involvement of ARF6-dependent molecular pathway in brain hyperexcitability and seizures, and confirmed the emerging role of subtle cytoarchitectural alterations in the etiology of this group of common epileptic disorders. 2010 The American Society of Human Genetics.

    BACKGROUND: Mood disorders have been described as the commonest psychiatric disorders in patients with temporal lobe epilepsy. Secondary depression in temporal lobe epilepsy could be interpreted either as an adjustment reaction to a chronic disease or as a limbic dysfunction. To clarify this issue, a controlled study of psychiatric disorders was conducted in different forms of epileptic and non-epileptic chronic conditions. METHODS: Twenty outpatients with temporal lobe epilepsy, 18 outpatients with juvenile myoclonic epilepsy--a primary generalised seizure disorder--20 matched type I diabetic patients, and 20 matched normal controls were assessed by a structured interview (SADS) and by self rating scales (Beck depression inventory (BDI) and the state and trait anxiety scales STAIX1 and STAIX2). RESULTS: Sixteen (80%) patients with temporal lobe epilepsy fulfilled the criteria for a psychiatric diagnosis at the SADS interview with a significantly higher frequency than patients with juvenile myoclonic epilepsy (22%) and diabetic patients (10%) (P personality or anxiety disorder. Patients with temporal lobe epilepsy scored significantly higher on BDI, STAIX1, and STAIX2 than the three control groups (P personality disorders, often in comorbidity, than patients with juvenile myoclonic epilepsy and diabetic patients suggesting that these psychiatric disorders are not an adjustment reaction to a chronic disease but rather reflect a limbic dysfunction.

    The aim of this study was to investigate life satisfaction in women with epilepsy during and after pregnancy. The study was based on the Norwegian Mother and Child Cohort Study, including 102,265 women with and without epilepsy from the general population. Investigation took place at pregnancy weeks 15-19 and 6 and 18months postpartum. Women with epilepsy were compared with a reference group without epilepsy. The proportion of women with epilepsy was 0.6-0.7% at all three time points. Women with epilepsy reported lower life satisfaction and self-esteem both during and after pregnancy compared with the references. Single parenting correlated negatively with life satisfaction in epilepsy during the whole study period. Epilepsy was associated with lower levels of relationship satisfaction and higher levels of work strain during pregnancy and lower levels of self-efficacy and satisfactory somatic health 18months postpartum. Adverse life events, such as divorce, were more common in women with epilepsy compared with the references, and fewer women with epilepsy had a paid job 18months postpartum. Reduced life satisfaction associated with epilepsy during and after pregnancy showed that, even in a highly developed welfare society, women with epilepsy struggle. Mothers with epilepsy and their partners should be examined for emotional complaints and partnership satisfaction during and after pregnancy.

  16. [Chronic diarrhea: etiologies and diagnostic evaluation].

    Schoepfer, A

    2008-04-30

    Chronic diarrhea is defined as a decrease in fecal consistency lasting for four or more weeks. A myriad of disorders are associated with chronic diarrhea. In developed countries, chronic diarrhea is mostly caused by non-infectious diseases. There are four pathogenic mechanisms leading to chronic diarrhea: osmotic diarrhea, secretory diarrhea, inflammatory diarrhea, and dysmotility. Overlaps between these mechanisms are possible. A 72-hour fecal collection as well as the fasting test are important diagnostic tools to identify the underlying pathomechanism. The identification of the pathomechanism narrows down the possible etiologies of chronic diarrhea and allows therefore a cost-saving diagnostic workup. The endoscopy is well established in the workup of chronic diarrhea. This article gives an overview about the main causes and mechanisms leading to chronic diarrhea and proposes an algorithm for the diagnostic evalution.

    2017-11-01

    Acute pancreatitis is a fascinating disease. In the United States, the two most common etiologies of acute pancreatitis are gallstones and excessive alcohol consumption. The diagnosis of acute pancreatitis is made with a combination of history, physical examination, computed tomography scan, and laboratory evaluation. Differentiating patients who will have a benign course of their pancreatitis from patients who will have severe pancreatitis is challenging to the clinician. C-reactive protein, pro-calcitonin, and the Bedside Index for Severity of Acute Pancreatitis appeared to be the best tools for the early and accurate diagnosis of severe pancreatitis. Early laparoscopic cholecystectomy is indicated for patients with mild gallstone pancreatitis. For patients who are going to have a prolonged hospitalization, enteral nutrition is preferred. Total parenteral nutrition should be reserved for patients who cannot tolerate enteral nutrition. Prophylactic antibiotics are not indicated for patients with pancreatic necrosis. Surgical intervention for infected pancreatic necrosis should be delayed as long as possible to improve patient outcomes.

  18. Etiology and Pathogenesis of Epithelial Ovarian Cancer

    Directory of Open Access Journals (Sweden)

    Samuel C. Mok

    2007-01-01

    Full Text Available Ovarian cancer is complex disease composed of different histological grades and types. However, the underlying molecular mechanisms involved in the development of different phenotypes remain largely unknown. Epidemiological studies identified multiple exogenous and endogenous risk factors for ovarian cancer development. Among them, an inflammatory stromal microenvironment seems to play a critical role in the initiation of the disease. The interaction between such a microenvironment, genetic polymorphisms, and different epithelial components such as endosalpingiosis, endometriosis, and ovarian inclusion cyst in the ovarian cortex may induce different genetic changes identified in the epithelial component of different histological types of ovarian tumors. Genetic studies on different histological grades and types provide insight into the pathogenetic pathways for the development of different disease phenotypes. However, the link between all these genetic changes and the etiological factors remains to be established.

    2006-04-01

    Millions of reproductive-age U.S. women experience premenstrual symptoms with varying degrees of severity. The large number and variety of premenstrual symptoms reported have made premenstrual disorders difficult to characterize. A number of mechanisms have been proposed to explain the etiology of premenstrual symptoms. Some women appear to have a genetic predisposition toward severe premenstrual symptoms or to have vulnerability traits that increase their risk. It has been suggested that 1 or more neurotransmitters and/or neurohormonal systems in certain women may have an abnormal response to normal fluctuations in gonadal hormones across the menstrual cycle. Premenstrual disorders can have a significant negative impact on a woman's quality of life and work productivity.

    Full Text Available In Latin America, community-acquired pneumonia remains a major cause of morbidity and mortality among children. Few studies have examined the etiology of pneumonia in Ecuador.This observational study was part of a randomized, double blind, placebo-controlled clinical trial conducted among children aged 2-59 months with severe pneumonia in Quito, Ecuador. Nasopharyngeal and blood samples were tested for bacterial and viral etiology by polymerase chain reaction. Risk factors for specific respiratory pathogens were also evaluated.Among 406 children tested, 159 (39.2% had respiratory syncytial virus (RSV, 71 (17.5% had human metapneumovirus (hMPV, and 62 (15.3% had adenovirus.
