Frontal lobe nonconvulsive status epilepticus: a case of epileptic stuttering, aphemia, and aphasia--not a sign of psychogenic nonepileptic seizures.

Stuttering is a repetitive, iterative disfluency of speech, and is usually seen as a developmental problem in childhood. Acquired causes in adults include strokes and medications. When stuttering occurs with seizure-like events, it is usually attributed to psychogenic nonepileptic seizures. We describe an elderly man who experienced personality change and bouts of stuttering, followed by anarthria with preserved writing and then aphasia affecting written and uttered language, and ending with confusion. EEG recordings showed nonconvulsive status epilepticus (NCSE) with focality in the left frontal region followed by bifrontal NCSE. This case enlarges our understanding of the behavioral correlates of focal frontal seizures to include simple partial seizures with speech and then language output disturbances (aphemia, then aphasia), progressing to complex partial phenomenology in the setting of frontal NCSE.
