Auras are frequent in idiopathic generalized epilepsy.

The occurrence of an aura is often considered evidence of a partial rather than an idiopathic generalized epilepsy syndrome. The authors examined this hypothesis by prospectively recording reports of auras by patients being admitted for video-EEG monitoring. Auras were equally common (70%) among patients with idiopathic generalized epilepsy as they were among those with localization-related epilepsy. Presence of an aura is not a reliable indicator of localization-related epilepsy.
