A new definition and classification of status epilepticus (SE) was recently published as Report of the ILAE Task Force on Classification of Status Epilepticus.
The new definition is applicable to all sorts of status. It includes two operational dimensions, first the time point t1 at which the abnormal prolonged seizure results and second time point 2 after which long term consequences may occur. These dimensions vary for different types of status. Furthermore, these dimension can be adapted if respective time periods will be better defined through scientific research results. Currently in most kinds of status the best estimate is given. A new diagnostic classification system is proposed, which is based on 4 axis: semiology, etiology, EEG correlates and age.
This classification will have direct impact on diagnosis and treatment of SE. In particular the timelines will change treatment of status and in particular in other then convulsive SE.
