   • 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.
