Summary
Benign rolandic seizures (BRS) and benign rolandic epilepsy (BRE) are common in children, with an excellent prognosis. Most children with BRS/BRE achieve seizure freedom without antiepileptic drugs.
Area of Science:
- Pediatric Neurology
- Epileptology
- Epidemiology
Background:
- Benign rolandic epilepsy (BRE) and benign rolandic seizures (BRS) are common childhood epilepsy syndromes.
- Accurate incidence and prognosis data are crucial for clinical management.
Purpose of the Study:
- To determine the incidence, clinical features, and prognosis of BRS and BRE in a defined population.
- To provide data to aid in the correct diagnosis and management of these conditions.
Main Methods:
- Population-based ascertainment of cases through EEG records.
- Verification of diagnosis via medical records review.
- Follow-up data collected from parents and physicians.
Main Results:
- Incidence of BRS: 6.2 per 100,000; BRE: 4.7 per 100,000 in Icelandic children (3-15 years).
- 95% of patients were seizure-free within 5 years of onset.
- All patients achieved seizure freedom, with no need for antiepileptic drugs at long-term follow-up.
Conclusions:
- BRS is a frequent diagnosis in pediatric epilepsy.
- The prognosis for BRS/BRE is excellent, with most children becoming seizure-free.
- Correct identification and differentiation from other epilepsies are important; treatment is not always necessary.
