Abstract
- A 44-year-old man showed recurrent paroxysmal amnesic attacks following viral encephalitis which, despite antiepileptic treatment, developed into status epilepticus. Interestingly, the amnesic attacks mainly consisted of amnesia for retrograde events. After recovery from status, he showed a persistent amnesia which was characterized as disproportionate retrograde amnesia for the past 20 years. We attribute the amnesic attacks in the acute stage to a transient epileptic amnesia and the profound retrograde amnesia in the chronic stage to status- or infection-related focal brain damage.
