[source] Evidence-based Treatment of Idiopathic Generalized Epilepsies with Older Antiepileptic DrugsEPILEPSIA, Issue 2005Nikolas Hitiris Summary:, Older antiepileptic drugs continue to play a major role in the treatment of the idiopathic generalized epilepsies. Comparative studies of ethosuximide and valproate have demonstrated equivalence in the treatment of childhood absence epilepsy. Valproate can be regarded as the recommended first-line treatment for juvenile myoclonic epilepsy based on case series reports. Studies in patients with generalized tonic-clonic seizures have not separated out idiopathic from secondary generalized events. Treatment for the other idiopathic generalized epilepsy syndromes lacks evidence other than a few case reports and diverse expert opinion. Further randomized controlled trials of older antiepileptic drugs are recommended to solidify the evidence-based treatment of the idiopathic generalized epilepsies. [source] Depression and Anxiety Disorders in Pediatric EpilepsyEPILEPSIA, Issue 5 2005Rochelle Caplan Summary:,Purpose: This study examined affective disorders, anxiety disorders, and suicidality in children with epilepsy and their association with seizure-related, cognitive, linguistic, family history, social competence, and demographic variables. Methods: A structured psychiatric interview, mood self-report scales, as well as cognitive and language testing were administered to 100 children with complex partial seizures (CPSs), 71 children with childhood absence epilepsy (CAE), and 93 normal children, aged 5 to 16 years. Parents provided behavioral information on each child through a structured psychiatric interview and behavior checklist. Results: Significantly more patients had affective and anxiety disorder diagnoses (33%) as well as suicidal ideation (20%) than did the normal group, but none had made a suicide attempt. Anxiety disorder was the most frequent diagnosis among the patients with a diagnosis of affective or anxiety disorders, and combined affective/anxiety and disruptive disorder diagnoses, in those with suicidal ideation. Only 33% received some form of mental health service. Age, verbal IQ, school problems, and seizure type were related to the presence of a diagnosis of affective or anxiety disorder, and duration of illness, to suicidal ideation. Conclusions: These findings together with the high rate of unmet mental health underscore the importance of early detection and treatment of anxiety disorders and suicidal ideation children with CPSs and CAE. [source] Genetic Architecture of Idiopathic Generalized Epilepsy: Clinical Genetic Analysis of 55 Multiplex FamiliesEPILEPSIA, Issue 5 2004Carla Marini Summary: Purpose: In families with idiopathic generalized epilepsy (IGE), multiple IGE subsyndromes may occur. We performed a genetic study of IGE families to clarify the genetic relation of the IGE subsyndromes and to improve understanding of the mode(s) of inheritance. Methods: Clinical and genealogic data were obtained on probands with IGE and family members with a history of seizures. Families were grouped according to the probands' IGE subsyndrome: childhood absence epilepsy (CAE), juvenile absence epilepsy (JAE), juvenile myoclonic epilepsy (JME), and IGE with tonic,clonic seizures only (IGE-TCS). The subsyndromes in the relatives were analyzed. Mutations in genes encoding ,1 and ,2 ,-aminobutyric acid (GABA)-receptor subunits, ,1 and ,1 sodium channel subunits, and the chloride channel CLC-2 were sought. Results: Fifty-five families were studied. 122 (13%) of 937 first- and second-degree relatives had seizures. Phenotypic concordance within families of CAE and JME probands was 28 and 27%, respectively. JAE and IGE-TCS families had a much lower concordance (10 and 13%), and in the JAE group, 31% of relatives had CAE. JME was rare among affected relatives of CAE and JAE probands and vice versa. Mothers were more frequently affected than fathers. No GABA-receptor or sodium or chloride channel gene mutations were identified. Conclusions: The clinical genetic analysis of this set of families suggests that CAE and JAE share a close genetic relation, whereas JME is a more distinct entity. Febrile seizures and epilepsy with unclassified tonic,clonic seizures were frequent in affected relatives of all IGE individuals, perhaps representing a nonspecific susceptibility to seizures. A maternal effect also was seen. Our findings are consistent with an oligogenic model of inheritance. [source] Prognostic Significance of Failure of the Initial Antiepileptic Drug in Children with Absence EpilepsyEPILEPSIA, Issue 6 2001Elaine Wirrell Summary: ,Purpose: In children with childhood absence epilepsy (CAE) and juvenile absence epilepsy (JAE), to determine the impact of failure of initial antiepileptic drug (AED) for lack of efficacy in eventual seizure control and long-term remission of epilepsy. Methods: Centralized EEG records for the province of Nova Scotia allowed identification of all children seen with CAE or JAE between 1977 and 1985. Information regarding success or failure of initial AED in fully controlling seizures and long-term seizure control and remission of epilepsy was collected by patient questionnaire and chart review. Results: Eighty-six of 92 eligible patients were followed up (75 CAE, 11 JAE). Initial AED treatment was successful in 52 (60%) of 86. Success tended to be greater for valproate (VPA) than for other AEDs (p = 0.07), and lower if generalized tonic,clonic or myoclonic seizures coexisted (p < 0.004 and p < 0.03). Terminal remission was more likely if the initial AED was successful than if it had failed (69% vs. 41%; p < 0.02). Compared with those in whom the initial AED was successful, subjects whose initial AED had failed were more likely to progress to juvenile myoclonic epilepsy (JME) at last follow-up (32% vs. 10%; p < 0.02) and to develop intractable epilepsy (17% vs. 2%; p < 0.04). Conclusions: Initial AED was successful in 60% of children with AE. If the first AED failed, the outcome was less favorable, with a lower rate of terminal remission and a higher rate of progression to JME and intractable epilepsy. [source] The health-related quality of life of childhood epilepsy syndromesJOURNAL OF PAEDIATRICS AND CHILD HEALTH, Issue 9 2003M Sabaz Objective: There is increasing awareness of the importance of assessing physical, psychological, social and behavioural well-being in chronic disease. The aim of this study was to examine the health-related quality of life (HRQoL) of children with common epilepsy syndromes and to explore if there are HRQoL differences between those syndromes. Methods: Each child had their epilepsy syndrome defined according to the International League Against Epilepsy classification. Epilepsy syndromes included symptomatic frontal, temporal, parietal/occipital lobe and partial unlocalized epilepsy, and two idiopathic epilepsies, childhood absence epilepsy (CAE) and benign rolandic epilepsy (BRE). Seizure semiology and ictal/interictal electroencephalogram (EEG) were determined for symptomatic partial epilepsy syndromes by video-EEG monitoring. HRQoL was evaluated with an epilepsy-specific instrument, the Quality of Life in Childhood Epilepsy Questionnaire, and two generic instruments, the Child Health Questionnaire and Child Behavior Checklist. Results: Children with symptomatic partial epilepsy syndromes were affected by epilepsy in a similar way and did not have unique HRQoL profiles. However, these children had significantly lower HRQoL scores compared to those with CAE or BRE. All children with epilepsy regardless of syndrome had a higher frequency of behavioural problems compared to normative data. Conclusion: These results indicate that children with epilepsy regardless of syndrome require evaluation of the psychosocial implications. There is a greater impact on HRQoL in symptomatic epilepsy compared to idiopathic epilepsy. Specific symptomatic partial syndromes did not differ in the degree they affect HRQoL. These findings have important implications for clinicians caring for children with epilepsy. [source] | ||||||||||
