First seizure presentation: Do multiple seizures within 24 hours predict recurrence?

We compared clinical features and prognosis of 72 adults with a first-ever seizure presentation comprising multiple discrete seizures within 24 hours to 425 patients presenting with a single seizure. Those presenting with multiple seizures were no more likely to have seizure recurrence, irrespective of etiology or treatment. Hence, a presentation with multiple seizures within 24 hours should be regarded as a single event, in keeping with the International League Against Epilepsy recommendations.
