Diagnostic criteria vary, though most practitioners diagnose as<unk>  for: one continuous, unremitting<unk> izure lasting longer than five minutes, or recurrent<unk> izures without regaining consciousness between<unk> izures for greater than five minutes. Previous definitions used a 30-minute time limit. Nonconvulsive<unk>  is believed to be under-diagnosed. New-onset refractory<unk>  (NORSE) is defined as<unk>  that does not respond to an anticonvulsant and lacks an obvious cause after two days of investigation.
