Classification and management of epilepsy and epileptic syndromes in a cohort of 202 school children- a 2 year follow up study- Sudan

BACKGROUND: In this paper, seizure types, and epilepsy syndromes are elucidated as per ILAE (2010) classification. A brief outline of the antiepileptic drug regimens used and the outcome of seizure control in a two -year period is presented. The applicability of the ILAE classification in resource limited countries has been revisited. METHODS: This is a descriptive prospective study, in which 202 patients were enrolled. The Cohort group was seen and evaluated by a pediatric neurologist at the Pediatric neurology Outpatients Department (OPD). Epilepsy was classified using the International League Against Epilepsy (ILAE) classification (2005–2009) report. All patients had an Electroencephalogram (EEG) at the start of the study, and this was repeated as deemed appropriate. Brain imaging (MRI) was done to patients when indicated. Treatment decisions were made by pediatric neurologists. Outcomes were categorized into four groups: fully recovered, well controlled, partially controlled and uncontrolled. RESULTS: The mean age is 10.5 + 2.7 years. Male to female ratio was 1.7: 1. Thirty five (17.3%) patients had generalized onset seizures, 46(22.8%) had focal onset seizures, 104(51.5%) had a specific epilepsy syndrome, and 17(8.4%) patients were unclassified. 170 (84.2%) patients were on mono-therapy on their initial visit, 30(14.8%) were on two Antiepileptic Drugs (AEDs) while two (1.0%) patients were on poly-therapy. After 2 years; 155(76.7%) patients were on mono-therapy, 36(17.8%) on two AEDs while ten were (4.0%) on polytherapy. One eighty (88.2%) patients were controlled. Fifteen (7.4%) of them were off medication after being seizure free for 2 years. Twenty (9.8%) have partial control, while two (1.0%) patients were uncontrolled. Patients with focal epilepsy, those on polytherapy and those with abnormal imaging had poor prognosis. CONCLUSIONS: The ILAE classification can be used in resource limited countries. Childhood epilepsies have a good prognosis provided they are well classified and treated.
