The mean duration of a secondarily generalized tonic-clonic (GTC) seizure is 53 to 62 seconds, and rarely lasts longer than 2 minutes.2,3 However, some seizures do not stop and progress to status epilepticus (SE), which may be convulsive (CSE), with clinically apparent motor (clonic) rhythmic jerking and/or (tonic) stiffening, or nonconvulsive (NCSE), with seizure activity on electroencephalography (EEG), and subtle or no obvious clinical signs. Status epilepticus is a neurological emergency often requiring management in the intensive care unit (ICU) for causes or complications of SE, or both.
