Initial ictal aphasia without epilepsy history is rare. This disorder is recognized hardly, because it is obscured by the lack of other seizure manifestations. A60 year-old woman acutely developed a motor aphasia. Presented manifestations were like transient ischemic attack and so, we initially treated as stroke. But motor aphasia repetitively occurred, and then EEG was performed. EEG revealed repetitive sharp discharges from the left temporoparietal area and after injection of valium, epileptiform discharge ceased and the aphasia disappeared.
