ObjectivesHospital admission in otherwise healthy patients following a first unprovoked seizure is controversial. We aimed to evaluate the influence of admission in a neurology department on the identification of risk factors for seizure recurrence in patients with a first unprovoked seizure.Materials And MethodsWe retrospectively reviewed the medical records of patients with a first unprovoked seizure, who were admitted to the neurology departments at two medical centers between 2007 and 2009. Risk factors for seizure recurrence included the following: abnormal neurological examination, abnormal brain CT scan, and epileptiform discharges on the EEG.ResultsThe study group included 97 patients (52 men) aged 18-85 years (mean 42). Eighty-seven (90%) patients were admitted following a generalized tonic-clonic seizure. Risk factors were identified in the emergency room (ER) in 36 (37%) patients, mainly including abnormalities of the neurological examination and brain CT scan. Nineteen (20%) patients had a risk factor which was not apparent during ER evaluation, consisting of epileptiform activity on the EEG. Five (5%) patients had recurrent seizures during admission, three of them without risk factors during the ER evaluation.ConclusionsRisk factors for seizure recurrence were detected during admission in nearly a quarter of the patients who presented to the emergency room with a first unprovoked seizure. Because the main advantage of admission is the EEG recording, we suggest that an early EEG should be obtained in these patients either during admission or through a special accelerated outpatient arrangement.© 2013 John Wiley & Sons A/S.
