Electroencephalography (EEG) is the gold standard for analyzing electrophysiological processes involved in epilepsy, as well as in several other dysfunctions of the central nervous system. Firstly, to properly interpret the EEG record, one must clearly have in mind the elements of a normal EEG. Secondly, to assist in producing useful information for clinical and research purposes, it is recommended to use standardized terminolo-gies and to follow an orderly EEG reporting approach. The EEG report gives a clinical interpretation in light of the diagnosis and must meet the expectations of the clinician. The EEG terminology should be understandable to other physicians who are not specialized in EEG. The review aims to provide a standardized format for reporting the results of adult routine scalp EEG.

Objective: Focal cortical dysplasia (FCD) is the most common cause of focal epilepsy in children and adults. The long-term seizure outcome has been reported in children, but very limited data are available for adults. The aim of this retrospective study is to provide long-term seizure outcome in adults with isolated FCD.Methods: A total of 23 adult patients operated on type I and II FCD were included. Medical history, seizure semiology, and radiological features were reviewed from the patients’ charts. Long-term seizure outcome was obtained with telephone interviews and last follow-up data available in archive.Results: At the last follow-up, 16 patients (69.6%) were totally seizure free even without aura and 7 patients (30.4%) continued to have seizure. Both type I (75%) and type II FCD (63.7%) showed higher seizure-free rate, and no significant difference was found (p=0.6).Conclusion: Surgery is safe and results in high seizure-free rate in adult patients with isolated FCD, but it is not enough because we cannot still explain why some patients continue to have seizure after complete removal of the dysplastic area.
