Nonconvulsive status epilepticus presenting as a subacute progressive aphasia.
We report a 62-year-old man with non-convulsive status epilepticus (NCSE) presenting as a progressive aphasia that developed insidiously over 5 weeks. On video-EEG monitoring, aggravation of the aphasia coincided with occurrence of seizure activities arising from the left fronto-temporal area. Brain MRI was noncontributory but a fluorodeoxyglucose-PET scan revealed a hypometabolism in the left anterior temporal area. Following anticonvulsant treatment, aphasia recovered gradually over several weeks despite prompt resolution of epileptic discharges on EEG. Our patient's findings, gradual onset of isolated aphasia with gradual resolution after initiation of treatment, may differ from previously reported cases with aphasic status epilepticus because their aphasia showed abrupt onset and rapid resolution with anticonvulsant medication.
