Background: Postictal encephalopathy is well known after status epilepticus (SE), but its prognostic impact and triggers are unknown. Here, we aimed to establish risk factors for the development of postictal encephalopathy and to study its impact on survival after discharge.
Methods: This retrospective cohort study comprised adult patients diagnosed with first nonanoxic SE at Odense University Hospital between January 2008 and December 2017.
Objective: In patients with status epilepticus (SE), the clinical significance of ictal changes on magnetic resonance imaging (MRI) is insufficiently understood. We here studied whether the presence of ictal MRI changes was associated with neurological deterioration at discharge.
Methods: The retrospective cohort comprised all identifiable patients treated at Odense University Hospital in the period 2008-2017.
Purpose: To investigate differences in long-term survival and short-term neurological deficits in adult patients fulfilling either sub-criterion of the Salzburg Consensus Criteria (SC) for non-convulsive status epilepticus (NCSE).
Methods: We retrospectively identified a cohort of patients with first-time NCSE epilepticus at Odense University Hospital from 2014 to 2017. Results of electroencephalograms at admission were dichotomized according to the SC (more than 25 epileptiform discharges/10 s was defined as the fast criterion), and groups were compared statistically through survival analysis and in a logistic regression model adjusting for established prognostic determinants in status epilepticus.
Importance: Early prediction of long-term mortality in status epilepticus is important given the high fatality rate in the years after diagnosis.
Objective: To improve prognostication of long-term mortality after status epilepticus diagnosis.
Design, Settings, And Participants: This retrospective, multicenter, multinational cohort study analyzed adult patients who were diagnosed with and treated for status epilepticus at university hospitals in Odense, Denmark, between January 1, 2008, and December 31, 2017, as well as in Oslo, Norway; Marburg, Germany; and Frankfurt, Germany.
