The Electroencephalogram in Status Epilepticus

  • Susan T. Herman
Part of the Current Clinical Neurology book series (CCNEU)

Abstract

Status epilepticus (SE) occurs when a continuous epileptic seizure lasts for more than 30 min, or intermittent epileptic seizures recur without intervening recovery to baseline neurologic function (1). For practical clinical purposes, 10 min of continuous seizure activity is often used as a criterion for diagnosis of SE (2). While most cases of convulsive SE are easy to diagnose by clinical criteria alone, the electroencephalogram (EEG) is an essential tool for the diagnosis and classification of nonconvulsive SE (NCSE). EEG is also valuable in classifying SE and in monitoring the response to therapy. The clinical manifestations and treatment of SE are discussed thoroughly in other chapters; this chapter will focus on the electrographic patterns of SE and the utility of EEG for diagnosis, classification, and management of SE.
