[Non-convulsive status epilepticus manifesting as ictal catatonia: a case report].

A 66 year-old right-handed female was admitted to our hospital presenting with recurrent episodes of catatonic symptoms consisting of stupor, waxy flexibility, and catalepsy lasting about 5-20 minutes. A brain MRI showed no significant abnormalities. An scalp-electroencephalography (EEG) concurrent with the symptoms showed ictal EEG activities arising from the left fronto-central area, which evolved into the bilateral frontal and bilateral parietal areas together.
