Benign Epilepsy of Childhood With Rolandic Spikes: Typical and Atypical Variants

Clinical course and outcome were compared for 126 children with typical and atypical features of benign epilepsy of childhood with rolandic spikes (BECRS). A retrospective case series design was used, in the setting of a tertiary-care pediatric hospital. The subjects were subdivided into two groups, based on clinical presentation. Group A comprised children with typical features of BECRS (n = 66; 52%) and Group B, those with atypical features (n = 60; 48%). Patients’ charts were reviewed for demographic data, family history, comorbid conditions, atypical clinical features, anti-epileptic drugs, and outcome data. Comorbid disorders (e.g., attention deficit hyperactivity disorder, behavioral problems) were slightly more frequent in the atypical group. Overall, there was no difference between the time to become seizure free between the groups: by two years, 41 of 66 in Group A (62%) and 44 of 60 in Group B (71%) were controlled on medication and seizure free. Twenty of the 126 children (16%) required trial of a second anti-epileptic drug: 7 in Group A and 13 in Group B. Resolution of the epilepsy occurred in about the same length of time in both groups (but at different ages, consistent with different age of onset). Both groups had similar long-term outcome.
