title: Prolonged ictal aphasia: a diagnosis to consider.
abstract: Aphasia is a common symptom encountered by clinical neurologists. It is usually caused by strokes or lesions involving language regions of the brain, yet prolonged aphasia is rarely the sole manifestation of a simple partial status epilepticus. We report six patients, who suffered from prolonged ictal aphasia. All but one patient had a structural lesion in the left hemisphere, only three suffered from clinical seizures during or shortly prior to the aphasic episode. All patients had ictal patterns on the electroencephalogram (EEG), four of whom had periodic lateralized epileptiform discharges, and five showed frequent recurrent electrographic seizures during the aphasic state. The aphasia lasted several days in all patients, and it resolved after administration of antiepileptic drug treatment. In conclusion, prolonged ictal aphasia is a rare but important treatable cause of aphasia. Surface EEG recordings should be obtained in all patients with unexplained prolonged aphasia to diagnose this rare but treatable entity.
