Summary. Epileptic seizures are one of the main reasons for neurological visits in an emergency department. Convulsions represent a traumatic event for the patient and the family, with signifi cant medical and social consequences. Due to their prevalence and impact, the initial management is of vital importance. Although following the fi rst epileptic seizure, early recurrence diminishes after establishing treatment with antiepileptic drugs, the forecast for developing epilepsy and longterm outcomes are not altered by any early intervention. Detailed questioning based on the symptoms of the convulsions, the patient’s medical history and a full electroencephalogram and neuroimaging study make it possible to defi ne the risk of recurrence of the seizure and the possible diagnosis of epilepsy. Epileptic abnormalities, the presence of old or new potentially epileptogenic brain lesions, as well as nocturnal seizures, increase the risk of recurrence. Physicians must assess
each patient on an individual basis to determine the most suitable treatment, and explain the risk of not being treated versus the risk that exists if treatment with antiepileptic drugs is established.
