New-onset refractory status epilepticus (NORSE) is defined as a sudden onset of refractory status epilepticus in patients who do not have a history of epilepsy. It is a neurologic emergency, and determining the underlying etiology is an important factor for effectively managing and predicting the prognosis of NORSE. We describe the case of a 28-year-old woman who was hospitalized with NORSE secondary to an unknown etiology. ⋯ The patient failed to respond to traditional anticonvulsant therapy alone. With the addition of high-dose corticosteroids to aggressive anticonvulsant therapy, seizure control was achieved. Further studies are needed to determine the effectiveness of high-dose corticosteroid and anticonvulsant therapy followed by antibiotics in patients with NORSE secondary to CSD.
