Adult-onset epileptic aphasia.

Aphasia is a language disorder characterised by loss of ability to produce or comprehend written or spoken language. In majority of the cases, it is due to stroke. Aphasia may also present as an ictal or postictal state of temporal or frontal lobe seizures. Nevertheless, its isolated occurrence in individuals without a clear-cut history of seizures raises diagnostic difficulties with important therapeutic implications.A case of epileptic aphasia is reported in which the diagnosis was confirmed by electroencephalogram with a dramatic therapeutic response to an antiepileptic drug. © BMJ Publishing Group Limited 2018.
