Status epilepticus (SE) is an abnormally prolonged seizure state with a high risk of mortality and functional decline. The short-term case fatality rate is 7.6–33% across all seizure types (1). At hospital discharge, 23–58% of survivors have increased need for help in daily living (2–4). Of intensive care patients with refractory SE, less than half recover to baseline function, 20% die and 30% show new functional deficits (5). Aggressive treatment should be aimed at patients who are at a high risk of death or functional deterioration and who may benefit from intensive care.
