[Seizures in the emergency service: the clinical and therapeutic characteristics of 122 patients].

Introduction: Epileptic seizures are a common cause of admission in emergency services at hospitals. Performing the correct diagnosis can be difficult, and deciding when and which anti-seizure medication (ASM) to prescribe is critical. Our objective is to detail the characteristics of patients treated in a medium-sized hospital for this reason.

Patients and methods: A retrospective observational study was performed, including all the adult patients treated by the emergency service of the Lucus Augusti University Hospital between January 2022 and January 2023 with a diagnosis of epileptic seizure on discharge. The study recorded their demographic variables, history, whether it was their first seizure, the number of seizures, whether an anti-seizure medication was administered and which one, the diagnosis, the tests performed, and whether the patient was referred to the neurology service.

Results: A total of 122 patients were diagnosed with epileptic seizures in the emergency service. 50.8% of the patients were women. The mean age was 69.8 years. Neurological assessment was requested for 47.6%. 50.8% presented their first seizure. No diagnosis was performed in 46% of the cases, of which only 10 were evaluated by the neurology service. The most common etiology was vascular. An electroencephalogram was performed on 41.8%. Levetiracetam was practically the only drug administered when the neurology department was not consulted.

Conclusions: Early evaluation of patients with their first seizure in the emergency service by a neurological specialist is crucial for the diagnosis of epilepsy. The same anti-seizure medication is almost always prescribed when no cross-consultation takes place.
