ObjectivesThere is little information available from the Middle Eastern region on adult patients presenting with first seizure. The objectives of this study were to describe epidemiological characteristics of patients presenting to the emergency department (ED) in Doha, Qatar, with first seizure and to determine the incidence of computed tomographic (CT) scan abnormalities.MethodsA retrospective cohort study was conducted on all adult patients with first seizure presenting to Hamad General Hospital ED over a 1-year period (June 2012 through May 2013). Electronic patient records were reviewed for demographics, neuroimaging, electroencephalography, laboratory test results, and medications administered.ResultsThere were 439 patients who satisfied inclusion criteria. Patients were aged a mean of 35.3 years (95% confidence interval [CI] = 33.92 to 36.69 years) with a male-to-female ratio of five to one. CT abnormalities were detected in 154 patients (35.3%; 95% CI = 30.81% to 39.82%). Out of reported abnormal scans, 14.7% patients had significant abnormalities such as neurocysticercosis (9.2%); brain metastasis and neoplasm (3.4%); and subarachnoid and subdural hemorrhage, cavernous sinus thrombosis, acute stroke, and brain edema (2.0%). None of the patients had any electrolyte abnormalities, and three patients had hypoglycemia. Patients with initial abnormal CT brain results were more likely to have recurrent seizures (OR = 1.65; 95% CI = 1.11 to 2.45) within 6 months.ConclusionsAdults who presented with first seizure to the ED in Qatar had a young male predominance, and a high proportion of brain CT scans were reported as abnormal. It is recommended that all such patients in this population should undergo prompt CT scanning in the ED, but the utility of routine electrolyte tests requires further investigation.© 2014 by the Society for Academic Emergency Medicine.
