Risk Factors of Intractable in Childhood with Generalized Epilepsy

Research output: Contribution to journalArticlepeer-review

Abstract

Background: Generalized epilepsy is the most common type of epilepsy in children. Limited datas of intractable epilepsy risk factors are available at present. Therefore, more studies are needed to investigate the risk factors of intractable epilepsy in order to manage and educate both patients and parents. Objective: (1) to describe characteristic and frequency of intractable epilepsy in children with generalized epilepsy, (2) to investigate the role of age onset of seizure, initial seizure frequency, type of seizure, early gross motor developmental status, early therapeutic response, early EEG description and cerebral MRI/CT scan as risk factors of intractable epilepsy in children with generalized epilepsy, (3) to investigate the role of gross motor developmental status evolution and epileptiform EEG evolution as risk factors of intractable epilepsy. Methods: Retrospective cohort study was conducted at neurology outpatient pediatric RSCM and private outpatient clinic between September to December 2014. The inclusion criteria was generalized epilepsy children age 1 month of corrected age to 18 years old which has been treated with antiepileptic drugs for at least 6 months. Risk factors were analyze with bivariate and multivariate analysis. Results: Prevalence of intractable generalized epilepsy is 21%. Most subject are >3 years old 85(83%) subject. Bivariate analysis showed that age onset of seizure (OR 11,4 CI95% 3,45-37,62), initial seizure frequency ≥5 times/day (OR 8,5 CI 95% 2,90-24,80), non-responder of early treatment (OR 160 CI 95% 19,12-1339,06), unfavorable gross motor development evolution (OR 4,9 CI 95% 1,79-13,67) and unfavorable epileptiform EEG evolution (OR 10 CI 3,25-30,92) are significantly associated with intractable epilepsy. The most important among those risk factors based on multivariate analysis are non responder of early treatment with OR 144,3 (CI95% 15,47-1345,59) and age onset < 1 year old with OR 9,6 (CI 1,78-51,92). Conclusions: Prevalence of intractable generalized epilepsy is 21%. Non-responder early treatment and age onset of seizure < 1 year old are strongly associated with intractable generalized epilepsy.;Background: Generalized epilepsy is the most common type of epilepsy in children. Limited datas of intractable epilepsy risk factors are available at present. Therefore, more studies are needed to investigate the risk factors of intractable epilepsy in order to manage and educate both patients and parents.
