Background: According to statistics, at least four percent of people experience one or more nonfebrile seizures in their life span. Continuous Electroencephalography (cEEG) Monitoring is a useful diagnostic tool for seizure detection. The purpose of this study was to investigate EEG findings in first-time seizure patients referred to emergency department (ED). Methods: The present cross-sectional study was conducted on 80 first-time seizure patients admitted to ED, who were selected by convenience sampling method. The inclusion criteria were all patients aged more than 17 years with first-time seizure and informed written consent to participate in the study, and the exclusion criteria were cases where the seizure was not confirmed by a neurologist. An EEG was taken in the ED from the patient within 24 hours of the first attack. Finally, the frequency of pathological changes in EEG findings was determined in these patients. The statistical data were analyzed by SPSS software using descriptive statistics (measures of central tendency and dispersion and frequency distribution) and inferential statistics. Results: The patients consisted of 35 (43.8%) males and 45 (56.2%) females. The patients had a mean age of 52.54±19.33 years and a median of 53 years. Among the patients, 46 (57.5%) had normal EEG findings, and 34 (42.5%) had abnormal (pathological) EEG findings. Conclusion: According to the results of this study, 42.5% of patients had abnormal EEG findings, but it seems that accurate examination would require the use of other diagnostic tools along with EEG to diagnose patients with epilepsy and seizure more precisely.

Abnormal hyperexcitable electrical discharges of the cerebral cortex lead to the disturbance between the inhibitory and excitatory balance of the neural network. Seizure is caused by four main mechanisms, including metabolic, structural, inflammatory, and infectious mechanisms. Seizures are classified as partial and generalized based on the isolation in a specific area in one brain hemisphere or passing through the nerve fibers and spreading to the other hemisphere as well. Epilepsy is defined as the occurrence of more than two unprovoked and unpredicted repeated seizures. Epilepsy affects more than three million individuals in the United States and approximately 50 million individuals worldwide. Epilepsy may be of an unknown origin, while it could also be associated with certain syndromes. General and specific approaches to seizure treatment encompass a wide range of factors. The general approach should be focused on reassurance and raising the awareness of the patients and their family, and the specific treatment is focused on utilizing pharmacological and surgical approaches. In general, the surgical approaches used for medication-refractory seizures are both palliative and curative, showing promising results if the epileptogenic area is localized using a multidisciplinary approach via live video-electroencephalography monitoring or direct intracranial electrode placement. In addition, the utilization of live modern imaging modalities coupled with surgical approaches could enhance the success rate of the treatment and increase the seizure-free duration.
