Recent developments in the diagnosis and treatment of status epilepticus.

Despite increased understanding of its potential complications, status epilepticus (SE) frequently remains difficult to diagnose and treat. Advances in continuous electroencephalogram (EEG) monitoring facilitate more rapid identification of SE, even without visible clinical signs of seizures. EEG monitoring assists in modifying SE treatment and in making a prognosis. Despite the improved recognition of SE, some patients continue to seize after treatment with intravenous benzodiazepines and other medications. There are new uses for valproic acid, levetiracetam, and topiramate, and they have evidence of efficacy in treating different forms of SE. If medical treatments do not terminate SE, other interventions, such as surgery and stimulation procedures, may promote seizure cessation. This article reviews recent studies evaluating the use of continuous EEG monitoring in the setting of SE, new uses of anticonvulsants, and nonpharmacologic interventions for SE.
