Nonconvulsive status epilepticus presenting as epileptic nystagmus in a patient with herpes encephalitis.

Epileptic nystagmus (EN) is characterized by rhythmic ocular oscillations or quick, repetitive eye movements secondary to seizure activity. The fast component of EN is known to be contralateral to the epileptogenic focus. There are few reports EN occurring patients in nonconvulsive status epilepticus (NCSE). We report such a patient in the setting of herpes encephalitis.
