, 2009 in the department of Neurology at Rostock University were identi fied. The first EEG of each treatment episode, in which an EEG was recorded, was evaluated. Sta tistical analyses were performed in order to find out whether there is an association of a certain EEG pattern with a particular subtype of SE or whether some EEG patterns signify a worse out come than others. Results: In 35 treatment episodes of an SE at least one EEG was obtained during the actual treatment. There was no association of a cer tain EEG pattern with a particular subtype of SE. Periodic epileptiform discharges were seen more often in nonlimbic complex partial status epilepticus and cases of coma due to acute brain injury with epileptiform EEG changes than in nonconvulsive status epilepticus (NCSE) in the postictal phase of tonic-clonic seizures. These results are at variance with the published litera ture, where the frequent occurrence of periodic epileptiform discharges in NCSE in the postictal phase of tonicclonic seizures is reported. Back ground slowing with a frequency in the theta range or lower was associated with disability to perform the activities of daily life without any help. On discharge patients with periodic epi leptic discharges were more disabled than those without this pattern.
