New-onset refractory status epilepticus: a retrospective cohort study

Status epilepticus (SE) is a neurological emergency with more than 180 described causes; common causes include medication change or noncompliance in patients with known epilepsy, toxic-metabolic disturbances, sedative/hypnotic withdrawal, acute/remote stroke, and brain tumor [1]. The term new-onset refractory SE (NORSE) is applied to a patient without a prior diagnosis of epilepsy or other preexisting relevant neurological disorder, with new onset of refractory SE (RSE) that does not respond to first- and second-line antiseizure drugs and no clear acute or active structural, toxic, or metabolic cause.
