In 2015 the ILAE Task Force on Classification of Status Epilepticus concluded that the evidence to define time points 1 and 2 in humans was incomplete. For tonic-clonic status epilepticus t1 is defined as 5 minutes and t2 as 30 minutes. For focal status epilepticus with impaired consciousness t1 is defined as 10 minutes and t2 over 60 minutes. For absence status epilepticus t1 is defined as 10-15 minutes and t2 is unknown. Status epilepticus is a condition that can have long-term consequences (after time point t2), including neuronal death, neuronal injury, and alteration of neuronal networks, depending on the type and duration of seizures.

Status epilepticus is a type of prolonged seizure. The definition is based on both the length of the seizure and the time point (t1) beyond which the seizure should be regarded as continuous seizure activity. The second time point (t2) is the time of ongoing seizure activity after which there is a risk of long-term consequences. See the comment for information on t1 and t2.
