title: Mortality after a first episode of status epilepticus in the United States and Europe.
abstract: OBJECTIVE
  In the last decade several studies have been published on incidence, etiology, and prognosis of status epilepticus (SE) with population-based data from the United States and Europe. The aim of this review is to summarize the available information on the epidemiology of SE and to outline the sources of the variability in reported mortality after SE.
  
  
  METHODS
  Comparison of mortality studies in SE from the United States and Europe.
  
  
  RESULTS
  The incidence of SE is lower in Europe (9.9-15.8/10,000) than in the United States (18.3-41/100,000). The overall mortality after SE is similar in the two U.S. studies: the case fatality is 21% in Rochester, and 22% in Richmond. All European studies excluded SE after anoxic encephalopathy following cardiac arrest. This exclusion may partly explain the lower case fatality (around 10%) found in two of the European studies. The study from Bologna showed the highest case fatality (33%) even after exclusion of anoxic encephalopathy. The mortality in acute symptomatic SE was higher than for other forms of SE across all studies.
  
  
  CONCLUSIONS
  Short-term mortality after SE occurs mainly in the acute symptomatic group. Based on published data, it is not clear if differences in early management and medical treatment have any impact on prognosis or whether the differences can be attributed only to differences in distribution of the underlying causes in acute symptomatic SE. Future studies should address this issue.
