        Considering these data, the spatial relationships between lesions and the localization of interictal spikes can vary and seem to depend on the lesion type.

        The diagnosis of epilepsy is primarily clinical; however, routine interictal EEG plays a crucial role in the diagnosis and management of patients with this paroxysmal neurological disorder (Binnie and Stefan 1999; Pillai and Sperling 2006).

        This sleep disruption may, in part, be related to the interictal discharge. The interictal discharge is the electrical signature typically associated with epilepsy between seizures.

        This may be the reason why most authorities in the field recommend relying mainly on the ictal data, and less on the interictal EEG.
