In partial epilepsies, seizures are due to an electrographic focal discharge localized in one part of the brain. Electroclinical evaluation of seizures comprises clinical background, neuroradiological lesions, interictal and ictal EEG patterns and correlations between ictal EEG and semeiology of seizures. Ictal EEG patterns recorded from scalp electrodes may pose problem of interpretation. Ictal focal discharges may be undetectable or well localized, diffuse or generalized. Moreover, ictal EEG spread may precede or follow ictal clinical onset. Video-EEG monitoring is nowadays considered mandatory in the study of focal epileptic seizures. During Video-EEG recording patients are submitted to a particularly detailed clinical examination; the convergency between anatomo-electro-clinical data obtained permits to choose further presurgical investigations, if needed, in the aim to define the correct tailored surgical strategy for each patient, since ictal discharges are not classified in a systematic order and numerous types of initial ictal electrical pattern have been described. Nevertheless a low voltage fast activity, described during deep recordings, seems to be the most localizing ictal discharge.
