Factors precipitating breakthrough seizures in childhood epilepsy

Abstract

Abstract Background: Breakthrough seizures occur in 37% of epilepsy patients even though remission has been attained. Counseling on precipitating factors form an integral part of treatment along with anti-epileptic drugs (AEDs). Identification of precipitating factors may help in reducing unnecessary hospitalization and complications of breakthrough seizures. Materials and Methods: This retrospective study was conducted in a tertiary healthcare center in Puducherry. All children with epilepsy admitted with breakthrough seizures from January 2017 to December 2019 were included in the study. Those with neonatal seizures, diagnosis of either Neurocysticercosis or tuberculoma, cases without seizure free period of 6 months and case records without adequate details were excluded. Data regarding precipitating factors were collected from case records and analyzed using SPSS version 24.0 software. Results: Of the 80 children included in the study, mean age was 4.98 (±3.52) years and 56.3% were less than 5 years of age. In total, 90% (n = 72) of the participants had generalized epilepsy, of which 67 had generalized seizures, four had absence seizures and one had atonic seizures. Majority (85%) reported at least one possible precipitating factor for breakthrough seizures and common ones were fever (27.5%) and non-compliance to medication (26.25%). Most common reason for non-compliance was forgetting to take medication (38%). Also illiterate mothers and multiple AEDs had a significant association with non-compliance (P < 0.05). Conclusion: The results of our study stress the need on adequate counseling about possible precipitants and prescription on minimum AEDs whenever possible. Parents need to ensure strict adherence to AEDs and avoidance of trigger factors.
