•• This article is a special report of the ILAE on the definition and classification of status epilepticus. The experts propose a new definition of status epilepticus, with two operational dimensions: the length of the seizure and the time point (t1) beyond which the seizure should be regarded as “continuous seizure activity”; and the second time point (t2) representing the time of ongoing seizure activity associated with a risk of long-term consequences
