Abstract

Summary: Purpose: We wished to determine incidence, clinical features, and prognosis of benign rolandic seizures (BRS) and benign rolandic epilepsy (BRE) in a total population.

Methods: Cases were ascertained through review of all EEG records, and diagnosis was verified by review of medical records. Follow-up information regarding seizures and treatment was obtained from parents and treating physicians.

Results: In the Icelandic population aged 3–15 years, the incidence of BRS is 6.2 and BRE 4.7 in 100,000. Five years after onset 95% were seizure-free. At last follow-up, all were seizure free and had not been treated with antiepileptic drugs (AEDs) for at least 1 year.

Conclusions: Our study demonstrates that BRS is a common entity in children. The prognosis is excellent and treatment is not necessary in all cases. It is important to identify BREBRS correctly and distinguish it from other types of epilepsy.
